It was one of the first publications to focus solely on role-playing games. + +History +In 1964, Bruce Pelz of the Los Angeles Science Fiction Society (LASFS) began a weekly amateur press association named APA-L. In 1974, with the publication of Dungeons & Dragons by TSR, Inc., articles and comments about the new roleplaying game began to fill the pages of APA-L, a development to which Pelz objected. Lee Gold took note of this and started a new APA, Alarums and Excursions (the title taken from an Elizabethan drama stage direction that moved soldiers across a stage), to focus entirely on roleplaying games, attracting such material away from APA-L. The first issue appeared in June 1975. + +In addition to removing roleplaying games discussion out of APA-L, the initial aim of the publication was to prevent roleplaying games from becoming so divergent that people from different cities could not participate in games together. + +The June 2017 issue of Alarums and Excursions was number 500, with a color cover drawn by Lee Moyer and printed by Rob Heinsoo. + +Contents +Each issue is a collection of contributions from different authors, often featuring game design discussions, rules variants, write-ups of game sessions, reviews, and comments on others contributions. + +Although game reports and social reactions are common parts of many A&E contributions, it has also, over the years, become a testing ground for new ideas on the development of the RPG as a genre and an art form.

Although Gygax felt some of the contributors were "woefully lacking in background", and the quality of printing varied dramatically from issue to issue, he concluded, "For all of its faults, it is far and away the best D&D 'zine, and well worth reading. See for yourself why it rates a Major Triumph." + +In the June 1981 edition of Dragon (Issue #50), Dave Nalle reviewed Alarums and Excursions after its 63rd issue (November 1980), and although he found the writing style "a bit stuffy", with a "tendency for the writers to pat each other on the back", he still called it "the top APA publication...

He also coined the term and philosophical concept of 'pataphysics. + +Jarry was born in Laval, Mayenne, France, and his mother was from Brittany. He wrote in a variety of hybrid genres and styles, prefiguring the postmodern, including novels, poems, short plays and opéras bouffes, absurdist essays and speculative journalism. His texts are considered examples of absurdist literature and postmodern philosophy. + +Biography and works + +His father Anselme Jarry (1837–1895) was a salesman who descended into alcoholism; his mother Caroline, née Quernest (1842–1893), was interested in music and literature, but her family had a streak of insanity, and her mother and brother were institutionalized. The couple had two surviving children, a daughter Caroline-Marie, called Charlotte (1865–1925), and Alfred. In 1879 Caroline left Anselme and took the children to Saint-Brieuc in Brittany. + +In 1888 the family moved to Rennes, where Jarry entered the lycée at 15. There he led a group of boys who enjoyed poking fun at their well-meaning, but obese and incompetent physics teacher, a man named Hébert. Jarry and his classmate, Henri Morin, wrote a play they called Les Polonais and performed it with marionettes in the home of one of their friends. The main character, Père Heb, was a blunderer with a huge belly, three teeth (one of stone, one of iron and one of wood), a single, retractable ear and a misshapen body. In Jarry's later work Ubu Roi, Père Heb would develop into Ubu, one of the most monstrous and astonishing characters in French literature. + +At 17 Jarry passed his baccalauréat and moved to Paris to prepare for admission to the École Normale Supérieure. Though he was not admitted, he soon gained attention for his original poems and prose-poems. A collection of his work, Les minutes de sable mémorial, was published in 1893. + +That same year, Jarry contracted influenza. His mother and sister tended him, but once he recovered his mother fell ill of the disease and died; two years later his father perished from influenza as well, leaving Jarry a small inheritance which he quickly spent. + +Jarry had meantime discovered the pleasures of alcohol, which he called "my sacred herb" or, when referring to absinthe, the "green goddess". A story is told that he once painted his face green and rode through town on his bicycle in its honour (and possibly under its influence). + +When he was drafted into the army in 1894, his gift for turning notions upside down defeated attempts to instill military discipline. The sight of the diminutive Jarry in a uniform much too large for his less than 5-foot frame – the army did not issue uniforms small enough – was so disruptively funny that he was excused from parades and marching drills. Eventually the army discharged him for medical reasons. His military experience eventually inspired his novel Days and Nights. + +In his youth, Jarry was homosexually inclined, although like many bohemians he disavowed sexual categorization. A brief but passionate relationship with future poet Léon-Paul Fargue inspired his semi-autobiographical play Haldernablou (1894). + +Jarry returned to Paris and applied himself to writing, drinking and the company of friends who appreciated his witty, sweet-tempered and unpredictable conversation. This period is marked by his intense involvement with Remy de Gourmont in the publication of L'Ymagier , a luxuriously produced "art" magazine devoted to the symbolic analysis of medieval and popular prints. Symbolism as an art movement was in full swing at this time, and L'Ymagier provided a nexus for many of its key contributors. Jarry's play Caesar Antichrist (1895) drew on this movement for material. This is a work that bridges the gap between serious symbolic meaning and the type of critical absurdity with which Jarry would soon become associated. Using the biblical Book of Revelation as a point of departure, Caesar Antichrist presents a parallel world of extreme formal symbolism in which Christ is resurrected not as an agent of spirituality but as an agent of the Roman Empire that seeks to dominate spirituality. It is a unique narrative that effectively links the domination of the soul to contemporaneous advances in the field of Egyptology such as the 1894 excavation of the Narmer Palette, an ancient artifact used for situating the rebus within hermeneutics. The character Ubu Roi first appears in this play. + +The spring of 1896 saw the publication, in Paul Fort's review Le Livre d'art, of Jarry's 5-act play Ubu Roi, the rewritten and expanded Les Polonais of his school days. Ubu Rois savage humour and monstrous absurdity, unlike anything thus far performed in French theatre, seemed unlikely to ever actually be performed on stage. However, impetuous theatre director Aurélien-Marie Lugné-Poe took the risk, producing the play at his Théâtre de l'Œuvre. + +On opening night (10 December 1896), with traditionalists and the avant-garde in the audience, King Ubu (played by Firmin Gémier) stepped forward and intoned the opening word, "Merdre!" (often translated as "Pshit" or "Shittr!" in English). A quarter of an hour of pandemonium ensued: outraged cries, booing, and whistling by the offended parties, countered by cheers and applause by the more bohemian contingent. Such interruptions continued through the evening. At the time, only the dress rehearsal and opening night performance were held, and the play was not revived until after Jarry's death. + +The play brought fame to the 23-year-old Jarry, and he immersed himself in the fiction he had created. Gémier had modelled his portrayal of Ubu on Jarry's own staccato, nasal vocal delivery, which emphasized each syllable (even the silent ones). From then on, Jarry would always speak in this style. He adopted Ubu's ridiculous and pedantic figures of speech; for example, he referred to himself using the royal we, and called the wind "that which blows" and the bicycle he rode everywhere "that which rolls." + +Jarry moved into a flat which the landlord had created through the unusual expedient of subdividing a larger flat by means of a horizontal rather than a vertical partition. The diminutive Jarry could just manage to stand up in the place, but guests had to bend or crouch. Jarry also took to carrying a loaded revolver. In response to a neighbour's complaint that his target shooting endangered her children, he replied, "If that should ever happen, ma-da-me, we should ourselves be happy to get new ones with you." + +With Franc-Nohain and Claude Terrasse he co-founded the Théâtre des Pantins, which in 1898 was the site of marionette performances of Ubu Roi. + +Living in worsening poverty, neglecting his health and drinking excessively, Jarry went on to write the novel Le Surmâle (The Supermale), which is partly a satire on the Symbolist ideal of self-transcendence. + +Unpublished until after his death, his fiction Exploits and Opinions of Dr. Faustroll, Pataphysician (Gestes et opinions du docteur Faustroll, pataphysicien) describes the exploits and teachings of a sort of antiphilosopher who, born at age 63, travels through a hallucinatory Paris in a sieve and subscribes to the tenets of 'pataphysics. 'Pataphysics deals with "the laws which govern exceptions and will explain the universe supplementary to this one." In 'pataphysics, every event in the universe is accepted as an extraordinary event. + +Jarry once wrote, expressing some of the bizarre logic of 'pataphysics, "If you let a coin fall and it falls, the next time it is just by an infinite coincidence that it will fall again the same way; hundreds of other coins on other hands will follow this pattern in an infinitely unimaginable fashion." + +In his final years, he was a legendary and heroic figure to some of the young writers and artists in Paris. Guillaume Apollinaire, André Salmon and Max Jacob sought him out in his truncated apartment. Pablo Picasso was fascinated with Jarry. After Jarry's death Picasso acquired his revolver and wore it on his nocturnal expeditions in Paris. He later bought many of his manuscripts as well as executing a fine drawing of him. + +Jarry died in Paris on 1 November 1907 of tuberculosis, aggravated by drug and alcohol misuse. When he could not afford alcohol, he drank ether. It is recorded that his last request was for a toothpick. He was interred in the Cimetière de Bagneux, near Paris. + +The complete works of Alfred Jarry are published in three volumes by Gallimard in the collection Bibliothèque de la Pléiade. + +Selected works + +Plays + César-Antéchrist (1895) – (Caesar Antichrist) – which introduces Père Ubu and his symbolic meaning. + Ubu Roi (1896, revised from 1888) – (Ubu Rex) – which portrays the ambition of Père Ubu. + Ubu Cocu, ou l'Archeopteryx (1897) – (Ubu Cuckolded) – which portrays the inconstancy of Ubu's closest. + Ubu Enchaíné (1899) – (Ubu in Chains) – which portrays Père Ubu in service. + Ubu Sur La Butte (1906) + +Novels + Les Jours et Les Nuits, roman d'un déserteur (1897) – (Days and Nights, novel of a deserter).

He was the father of three future rulers of Jerusalem, Sibylla, Baldwin IV, and Isabella I. + +Older scholarship mistook the two names Amalric and Aimery as variant spellings of the same name, so these historians erroneously added numbers, making Amalric to be Amalric I (1163–74) and King Aimery (1197–1205) to be "Amalric II". Now scholars recognize that the two names were not the same and no longer add the number for either king. Confusion between the two names was common even among contemporaries. + +Youth +Amalric was born in 1136 to King Fulk, the former count of Anjou married to the heiress of the kingdom, Queen Melisende. After the death of Fulk in a hunting accident in 1143, the throne passed jointly to Melisende and Amalric's older brother Baldwin III, who was still only 13 years old. Melisende did not step down when Baldwin came of age two years later, and by 1150 the two were becoming increasingly hostile towards each other. In 1152 Baldwin had himself crowned sole king, and civil war broke out, with Melisende retaining Jerusalem while Baldwin held territory further north. Amalric, who had been given the County of Jaffa as an apanage when he reached the age of majority in 1151, remained loyal to Melisende in Jerusalem, and when Baldwin invaded the south, Amalric was besieged in the Tower of David with his mother. Melisende was defeated in this struggle and Baldwin ruled alone thereafter. In 1153 Baldwin captured the Egyptian fortress of Ascalon, which was then added to Amalric's fief of Jaffa (see Battle of Ascalon). + +Amalric married Agnes of Courtenay in 1157. Agnes, daughter of Joscelin II of Edessa, had lived in Jerusalem since the western regions of the former crusader County of Edessa were lost in 1150. Patriarch Fulcher objected to the marriage on grounds of consanguinity, as the two shared a great-great-grandfather, Guy I of Montlhéry, and it seems that they waited until Fulcher's death to marry. Agnes bore Amalric three children: Sibylla, the future Baldwin IV (both of whom would come to rule the kingdom in their own right), and Alix, who died in childhood. + +Succession +Baldwin III died on 10 February 1163 and the kingdom passed to Amalric, although there was some opposition among the nobility to Agnes; they were willing to accept the marriage in 1157 when Baldwin III was still capable of siring an heir, but now the Haute Cour refused to endorse Amalric as king unless his marriage to Agnes was annulled. The hostility to Agnes, it must be admitted, may be exaggerated by the chronicler William of Tyre, whom she prevented from becoming Latin Patriarch of Jerusalem decades later, as well as from William's continuators like Ernoul, who hints at a slight on her moral character: "car telle n'est que roine doie iestre di si haute cite comme de Jherusalem" ("there should not be such a queen for so holy a city as Jerusalem"). Nevertheless, consanguinity was enough for the opposition. Amalric agreed and ascended the throne without a wife, although Agnes continued to hold the title Countess of Jaffa and Ascalon and received a pension from that fief's income. Agnes soon thereafter married Hugh of Ibelin, to whom she had been engaged before her marriage with Amalric. The church ruled that Amalric and Agnes' children were legitimate and preserved their place in the order of succession. Through her children Agnes would exert much influence in Jerusalem for almost 20 years. + +Conflicts with the Muslim states + +During Baldwin III's reign, the County of Edessa, the first crusader state established during the First Crusade, was conquered by Zengi, the Turkic emir of Aleppo. Zengi united Aleppo, Mosul, and other cities of northern Syria, and intended to impose his control on Damascus in the south. The Second Crusade in 1148 had failed to conquer Damascus, which soon fell to Zengi's son Nur ad-Din. Jerusalem also lost influence to Byzantium in northern Syria when the Empire imposed its suzerainty over the Principality of Antioch. Jerusalem thus turned its attention to Egypt, where the Fatimid dynasty was suffering from a series of young caliphs and civil wars. The crusaders had wanted to conquer Egypt since the days of Baldwin I, who died during an expedition there. The capture of Ascalon by Baldwin III made the conquest of Egypt more feasible. + +Invasions of Egypt + +Amalric led his first expedition into Egypt in 1163, claiming that the Fatimids had not paid the yearly tribute that had begun during the reign of Baldwin III. The vizier, Dirgham, had recently overthrown the vizier Shawar, and marched out to meet Amalric at Pelusium, but was defeated and forced to retreat to Bilbeis. The Egyptians then opened up the Nile dams and let the river flood, hoping to prevent Amalric from invading any further. Amalric returned home but Shawar fled to the court of Nur ad-Din, who sent his general Shirkuh to settle the dispute in 1164. In response Dirgham sought help from Amalric, but Shirkuh and Shawar arrived before Amalric could intervene and Dirgham was killed. Shawar, however, feared that Shirkuh would seize power for himself, and he too looked to Amalric for assistance. Amalric returned to Egypt in 1164 and besieged Shirkuh in Bilbeis until Shirkuh retreated to Damascus. + +Amalric could not follow up on his success in Egypt because Nur ad-Din was active in Syria, having taken Bohemund III of Antioch and Raymond III of Tripoli prisoner at the Battle of Harim during Amalric's absence. Amalric rushed to take up the regency of Antioch and Tripoli and secured Bohemund's ransom in 1165 (Raymond remained in captivity until 1173). The year 1166 was relatively quiet, but Amalric sent envoys to the Byzantine Empire seeking an alliance and a Byzantine wife, and throughout the year had to deal with raids by Nur ad-Din, who captured Banias. + +In 1167, Nur ad-Din sent Shirkuh back to Egypt and Amalric once again followed him, establishing a camp near Cairo; Shawar again allied with Amalric and a treaty was signed with the caliph al-Adid himself. Shirkuh encamped on the opposite side of the Nile. After an indecisive battle, Amalric retreated to Cairo and Shirkuh marched north to capture Alexandria; Amalric followed and besieged Shirkuh there, aided by a Pisan fleet from Jerusalem. Shirkuh negotiated for peace and Alexandria was handed over to Amalric. However, Amalric could not remain there indefinitely, and returned to Jerusalem after exacting an enormous tribute. + +Byzantine alliance + +After his return to Jerusalem in 1167, Amalric married Maria Comnena, a great-grandniece of Byzantine emperor Manuel I Comnenus. The negotiations had taken two years, mostly because Amalric insisted that Manuel return Antioch to Jerusalem. Once Amalric gave up on this point he was able to marry Maria in the Cathedral of Tyre on August 29, 1167. During this time the queen dowager, Baldwin III's widow Theodora, eloped with her cousin Andronicus to Damascus, and Acre, which had been in her possession, reverted into the royal domain of Jerusalem. It was also around this time that William of Tyre was promoted to archdeacon of Tyre, and was recruited by Amalric to write a history of the kingdom. + +In 1168 Amalric and Manuel negotiated an alliance against Egypt, and William of Tyre was among the ambassadors sent to Constantinople to finalize the treaty. Although Amalric still had a peace treaty with Shawar, Shawar was accused of attempting to ally with Nur ad-Din, and Amalric invaded. The Knights Hospitaller eagerly supported this invasion, while the Knights Templar refused to have any part in it. In October, without waiting for any Byzantine assistance (and in fact without even waiting for the ambassadors to return), Amalric invaded and seized Bilbeis. The inhabitants were either massacred or enslaved. Amalric then marched to Cairo, where Shawar offered Amalric two million pieces of gold. Meanwhile, Nur ad-Din sent Shirkuh back to Egypt as well, and upon his arrival Amalric retreated. + +Rise of Saladin +In January 1169 Shirkuh had Shawar assassinated. Shirkuh became vizier, although he himself died in March, and was succeeded by his nephew Saladin. Amalric became alarmed and sent Frederick de la Roche, Archbishop of Tyre, to seek help from the kings and nobles of Europe, but no assistance was forthcoming. Later that year however a Byzantine fleet arrived, and in October Amalric launched yet another invasion and besieged Damietta by sea and by land. The siege was long and famine broke out in the Christian camp; the Byzantines and crusaders blamed each other for the failure, and a truce was signed with Saladin. Amalric returned home. + +Now Jerusalem was surrounded by hostile enemies. In 1170 Saladin invaded Jerusalem and took the city of Eilat, severing Jerusalem's connection with the Red Sea. Saladin, who was set up as Vizier of Egypt, was declared Sultan in 1171 upon the death of the last Fatimid caliph. Saladin's rise to Sultan was an unexpected reprieve for Jerusalem, as Nur ad-Din was now preoccupied with reining in his powerful vassal. Nevertheless, in 1171 Amalric visited Constantinople himself, leaving Jobert of Syria as regent, and envoys were sent to the kings of Europe for a second time, but again no help was received. Over the next few years the kingdom was threatened not only by Saladin and Nur ad-Din, but also by the Assassins. In one episode, the Knights Templar murdered some Assassin envoys, leading to further disputes between Amalric and the Templars. + +Death +Nur ad-Din died in 1174, upon which Amalric immediately besieged Banias. On the way back after giving up the siege he fell ill from dysentery, which was ameliorated by doctors but turned into a fever in Jerusalem. William of Tyre explains that "after suffering intolerably from the fever for several days, he ordered physicians of the Greek, Syrian, and other nations noted for skill in diseases to be called and insisted that they give him some purgative remedy." Neither they nor Latin doctors could help, and he died on July 11, 1174. + +Maria Comnena had borne Amalric two daughters: Isabella, who would eventually marry four husbands in turn and succeed as queen, was born in 1172; and a stillborn child some time later. On his deathbed Amalric bequeathed Nablus to Maria and Isabella, both of whom would retire there. The leprous child Baldwin IV succeeded his father and brought his mother Agnes of Courtenay (now married to her fourth husband) back to court. + +Physical characteristics +William was a good friend of Amalric and described him in great detail. "He had a slight impediment in his speech, not serious enough to be considered as a defect but sufficient to render him incapable of ready eloquence. He was far better in counsel than in fluent or ornate speech." Like his brother Baldwin III, he was more of an academic than a warrior, who studied law and languages in his leisure time: "He was well skilled in the customary law by which the kingdom was governed – in fact, he was second to no one in this respect." He was probably responsible for an assize making all rear-vassals directly subject to the king and eligible to appear at the Haute Cour. Amalric had an enormous curiosity, and William was reportedly astonished to find Amalric questioning, during an illness, the resurrection of the body. He especially enjoyed reading and being read to, spending long hours listening to William read early drafts of his history. He did not enjoy games or spectacles, although he liked to hunt. He was trusting of his officials, perhaps too trusting, and it seems that there were many among the population who despised him, although he refused to take any action against those who insulted him publicly. + +He was tall and fairly handsome; "he had sparkling eyes of medium size; his nose, like that of his brother, was becomingly aquiline; his hair was blond and grew back somewhat from his forehead. A comely and very full beard covered his cheeks and chin. He had a way of laughing immoderately so that his entire body shook." He did not overeat or drink to excess, but his corpulence grew in his later years, decreasing his interest in military operations; according to William, he "was excessively fat, with breasts like those of a woman hanging down to his waist." +Amalric was pious and attended mass every day, although he also "is said to have absconded himself without restraint to the sins of the flesh and to have seduced married women..." Despite his piety he taxed the clergy, which they naturally opposed. + +As William says, "he was a man of wisdom and discretion, fully competent to hold the reins of government in the kingdom." He is considered the last of the early kings of Jerusalem. Within a few years, Emperor Manuel died as well, and Saladin remained the only strong leader in the east. + +Sources + + Bernard Hamilton, "Women in the Crusader States: The Queens of Jerusalem", in Medieval Women, edited by Derek Baker.

He also reigned as the King of Jerusalem from his marriage to Isabella I in 1197 to his death. He was a younger son of Hugh VIII of Lusignan, a nobleman in Poitou. After participating in a rebellion against Henry II of England in 1168, he went to the Holy Land and settled in the Kingdom of Jerusalem. + +His marriage to Eschiva of Ibelin (whose father was an influential nobleman) strengthened his position in the kingdom. His younger brother, Guy, married Sibylla, the sister of and heir presumptive to Baldwin IV of Jerusalem. Baldwin made Aimery the constable of Jerusalem at around 1180. He was one of the commanders of the Christian army in the Battle of Hattin, which ended with decisive defeat at the hands of the army of Saladin, the Ayyubid sultan of Egypt and Syria, on 4 July 1187. + +Aimery supported Guy even after he lost his claim to the Kingdom of Jerusalem according to most barons of the realm, because of the death of Sibylla and their two daughters. The new King of Jerusalem, Henry II of Champagne, arrested Aimery for a short period. After his release, he retired to Jaffa which was the fief of his elder brother, Geoffrey of Lusignan, who had left the Holy Land. + +After Guy died in May 1194, his vassals in Cyprus elected Aimery as their lord. He accepted the suzerainty of the Holy Roman emperor, Henry VI. With the emperor's authorization, Aimery was crowned King of Cyprus in September 1197. He soon married Henry of Champagne's widow, Isabella I of Jerusalem. He and his wife were crowned King and Queen of Jerusalem in January 1198. He signed a truce with Al-Adil I, the Ayyubid sultan of Egypt, which secured the Christian possession of the coastline from Acre to Antioch. His rule was a period of peace and stability in both of his realms. + +Early life + +Aimery was born before 1155. He was the fifth son of Hugh VIII of Lusignan and his wife, Burgundia of Rancon. His family had been noted for generations of crusaders in their native Poitou. His great-grandfather, Hugh VI of Lusignan, died in the Battle of Ramla in 1102; Aimery's grandfather, Hugh VII of Lusignan, took part in the Second Crusade. Aimery's father also came to the Holy Land and died in a Muslim prison in the 1160s. Earlier scholarship erroneously referred to him as Amalric (or Amaury, its French form), but evidences from documentaries shows he was actually called Aimericus, which is a distinct name (although it was sometimes confused with Amalricus already in the Middle Ages). Runciman and other modern historians erroneously refer to him as Amalric II of Jerusalem, because they confused his name with that of Amalric "I" of Jerusalem. + +Aimery joined a rebellion against Henry II of England (who also ruled Poitou) in 1168, according to Robert of Torigni's chronicle, but Henry crushed the rebellion. Aimery left for the Holy Land and settled in the Kingdom of Jerusalem. He was captured in a battle and held in captivity in Damascus. A popular tradition (which was first recorded by the 13th-century Philip of Novara and John of Ibelin) held, the King of Jerusalem, Amalric, ransomed him personally. + +Ernoul (whose reliability is questioned) claimed Aimery was a lover of Amalric of Jerusalem's former wife, Agnes of Courtenay. Aimery married Eschiva of Ibelin, a daughter of Baldwin of Ibelin, who was one of the most powerful noblemen in the Kingdom of Jerusalem. Amalric of Jerusalem, who died on 11 July 1174, was succeeded by his thirteen-year-old son by Agnes of Courtenay, Baldwin IV who suffered from leprosy. Aimery became a member of the royal court with his father-in-law's support. + +Aimery's youngest brother, Guy, married Baldwin IV's widowed sister, Sibylla, in April 1180. Ernoul wrote, it was Aimery who had spoken of his brother to her and her mother, Agnes of Courtenay, describing him as a handsome and charming young man. Aimery, continued Ernoul, hurried back to Poitou and persuaded Guy to come to the kingdom, although Sibylla had promised herself to Aimery's father-in-law. Another source, William of Tyre, did not mention that Aimery had played any role in the marriage of his brother and the King's sister. Consequently, many elements of Ernoul's report (especially Aimery's alleged journey to Poitou) were most probably invented. + +Constable of Jerusalem + +Aimery was first mentioned as Constable of Jerusalem on 24 February 1182. According to Steven Runciman and Malcolm Barber, he had already been granted the office shortly after his predecessor, Humphrey II of Toron, died in April 1179. Historian Bernard Hamilton writes that Aimery's appointment was the consequence of the growing influence of his brother and he was appointed only around 1181. + +Saladin, the Ayyubid sultan of Egypt and Syria, launched a campaign against the Kingdom of Jerusalem on 29 September 1183. Aimery defeated the sultan's troops in a minor skirmish with the support of his father-in-law and his brother, Balian of Ibelin. After the victory, the crusaders' main army could advance as far as a spring near Saladin's camp, forcing him to retreat nine days later. During the campaign, it turned out that most barons of the realm were unwilling to cooperate with Aimery's brother, Guy, who was the designated heir to Baldwin IV. The ailing King dismissed Guy and made his five-year-old nephew (Guy's stepson), Baldwin V, his co-ruler on 20 November 1183. + +In early 1185, Baldwin IV decreed that the Pope, the Holy Roman Emperor and the Kings of France and England were to be approached to choose between his sister, Sybilla, and their half-sister, Isabella, if Baldwin V died before reaching the age of majority. The leper King died in April or May 1185, his nephew in late summer of 1186. Ignoring Baldwin IV's decree, Sybilla was proclaimed queen by her supporters and she crowned her husband, Guy, king. Aimery was not listed among those who were present at the ceremony, but he obviously supported his brother and sister-in-law, according to Hamilton. + +As Constable, Aimery organised the army of the Kingdom of Jerusalem into units before the Battle of Hattin, which ended with the decisive victory of Saladin on 4 July 1187. Along with most commanders of the Christian army, Aimery was captured in the battlefield. During the siege of Ascalon, Saladin promised the defenders that he would set free ten persons whom they named if they surrendered. Aimery and Guy were among those whom the defenders named before surrendering on 4 September, but Saladin postponed their release until the spring of 1188. + +Most barons of the realm thought that Guy lost his claim to the Kingdom of Jerusalem when Sybilla and their two daughters died in late 1190, but Aimery remained loyal to his brother. Guy's opponents supported Conrad of Montferrat who married Sybilla's half-sister, Isabella in late November. An assembly of the noblemen of the realm unanimously declared Conrad the lawful king on 16 April 1192. Although Conrad was murdered twelve days later, his widow soon married Henry of Champagne, who was elected King of Jerusalem. To compensate Guy for the loss of Jerusalem, Richard I of England authorized him to purchase the island of Cyprus (that Richard had conquered in May 1191) from the Knights Templar. He was also to pay 40,000 bezants to Richard who donated the right to collect the sum from Guy to Henry of Champagne. Guy settled in Cyprus in early May. + +Aimery remained in the Kingdom of Jerusalem, which was reduced to a narrow strip of land along the coast of the Mediterranean Sea from Jaffa to Tyre. Henry of Champagne ordered the expulsion of the merchants from Pisa from Acre in May, because he accused them of plotting with Guy of Lusignan. After Aimery intervened on behalf of the merchants, the King had him arrested. Aimery was only released at the demand of the grand masters of the Templars and the Hospitallers. He retired to Jaffa that Richard of England had granted to Aimery's eldest brother, Geoffrey of Lusignan. + +Reign + +Lord of Cyprus + +Guy died in May 1194, and bequeathed Cyprus to his elder brother, Geoffrey. However Geoffrey had already returned to Poitou, thus Guy's vassals elected Aimery their new lord. Henry of Champagne demanded the right to be consulted about the succession in Cyprus, but the Cypriote noblemen ignored him. Around the same time, Henry of Champagne replaced Aimery with John of Ibelin as constable of Jerusalem. + +Aimery realized that the treasury of Cyprus was almost empty, because his brother had granted most landed property in the island to his supporters, according to Ernoul. He summoned his vassals to an assembly. After emphasizing that each of them owned more land than he had, he persuaded them one by one "either by force, or by friendship, or by agreement" to surrender some their rents and lands. + +Aimery dispatched an embassy to Pope Celestine III, asking him to set up Roman Catholic dioceses in Cyprus. He also sent his representative, Rainier of Gibelet, to the Holy Roman Emperor, Henry VI, proposing that he would acknowledge the emperor's suzerainty, if the emperor sent a royal crown to him. Aimery primarily wanted to secure the emperor's assistance against a potential Byzantine invasion of Cyprus, but he also wanted to strengthen his own legitimacy as king. Rainier of Gibelet swore loyalty to Henry VI on behalf of Aimery in Gelnhausen in October 1196. The emperor who had decided to lead a crusade to the Holy Land promised that he would personally crown Aimery king. He dispatched the archbishops of Brindisi and Trani to take a golden sceptre to Aimery as a symbol of his right to rule Cyprus. + +King of Cyprus + +Henry VI's two envoys landed in Cyprus in April or May 1196. Aimery may have adopted the title of king around that time, because Pope Celestin styled him as king already in a letter in December 1196. In the same month, the Pope set up a Roman Catholic archdiocese in Nicosia with three suffragan bishops in Famagusta, Limassol and Paphos. The Greek Orthodox bishops were not expelled, but their property and income was seized by the new Catholic prelates. + +Henry VI's chancellor, Conrad, Bishop of Hildesheim, crowned Aimery king in Nicosia in September 1197. Aimery did homage to the chancellor. The noblemen who owned fiefs in both Cyprus and the Kingdom of Jerusalem wanted to bring about a reconciliation between Aimery and Henry of Champagne. One of them, Baldwin of Beisan, Constable of Cyprus, persuaded Henry of Champage to visit Cyprus in early 1197. The two kings made peace, agreeing that Aimery's three sons were to marry Henry's three daughters. Henry also renounced the debt that Aimery still owed to him for Cyprus and allowed Aimery to garrison his troops at Jaffa. Aimery sent Reynald Barlais to take possession of Jaffa. Aimery again used the title of Constable of Jerusalem in November 1197, which suggests that he had also recovered that office as a consequence of his treaty with Henry of Champagne. + +King of two realms + +Henry of Champagne fell from the window in his palace and died in Acre on 10 September 1197. The aristocratic-yet-impoverished Raoul of Saint Omer was one of the possible candidates to succeed him, but the grand masters of the military orders opposed him vehemently. A few days later, Al-Adil I, the Ayyubid sultan of Egypt, occupied Jaffa. + +Conrad of Wittelsbach, Archbishop of Mainz, who arrived to Acre on 20 September, was the first to propose that the crown should be offered to Aimery. Since Aimery's first wife had died, he could marry the widowed Isabella I of Jerusalem, who was the queen. Although Aymar, Patriarch of Jerusalem, stated that the marriage would be uncanonical, Joscius, Archbishop of Tyre, started negotiations with Aimery who accepted the offer. The patriarch also withdrew his objections and crowned Aimery and Isabella king and queen in Tyre in January 1198. + +The Cypriot Army fought for the Kingdom of Jerusalem during Aimery's rule, but otherwise he administered his two realms separately. Even before his coronation, Aimery united his forces with the German crusaders who were under the command of Duke Henry I of Brabant to launch a campaign against the Ayyubid troops. They forced Al-Adil to withdraw and captured Beirut on 21 October. He laid siege to Toron, but he had to lift the siege on 2 February, because the German crusaders decided to return to the Holy Roman Empire after learning that Emperor Henry VI had died. + +Aimery was riding at Tyre when four German knights attacked him in March 1198. His retainers rescued him and captured the four knights. Aimery accused Raoul of Saint Omer of hiring the assailants and sentenced him to banishment without a trial by his peers. At Raoul's demand, the case was submitted to the High Court of Jerusalem which held that Aimery had unlawfully banished Raoul. Nevertheless, Raoul voluntarily left the kingdom and settled in Tripoli, because he knew that he had lost Aimery's goodwill. + +Aimery signed a truce with Al-Adil on 1 July 1198, securing the possession of the coast from Acre as far as to Antioch for the crusaders for five years and eight months. The Byzantine emperor, Alexios III Angelos, did not abandon the idea of recovering Cyprus. He promised that he would help a new crusade if Pope Innocent III excommunicated Aimery to enable a Byzantine invasion in 1201, but Innocent refused him, stating that the Byzantines had lost their right to Cyprus when Richard I conquered the island in 1191. + +Aimery kept the peace with the Muslims, even when Reynald II of Dampierre, who arrived at the head of 300 French crusaders, demanded that he launch a campaign against the Muslims in early 1202. After Aimery reminded him that more than 300 soldiers were needed to wage war against the Ayyubids, Reynald left the Kingdom of Jerusalem for the Principality of Antioch. An Egyptian emir seized a fortress near Sidon and made plundering raids against the neighboring territory. As Al-Adil failed to force the emir to respect the truce, Aimery's fleet seized 20 Egyptian ships and he invaded Al-Adil's realm. In retaliation, Al-Adil's son, Al-Mu'azzam Isa plundered the region of Acre. In May 1204, Aimery's fleet sacked a small town in the Nile Delta in Egypt. The envoys of Aimery and Al-Adil signed a new truce for six years in September 1204. Al-Adil ceded Jaffa and Ramleh to the Kingdom of Jerusalem and simplified the Christian pilgrims' visits in Jerusalem and Nazareth. + +After eating an excess of white mullet, Aimery fell seriously ill. He died after a short illness on 1 April 1205. His six-year-old son, Hugh I, succeeded him in Cyprus; and his widow ruled the Kingdom of Jerusalem until her own death four days later. + +Legacy + +Historian Mary Nickerson Hardwicke described Aimery as a "self-assured, politically astute, sometimes hard, seldom sentimentally indulgent" ruler. His rule was a period of peace and consolidation. He initiated the revision of the laws of the Kingdom of Jerusalem to specify royal prerogatives. The lawyers of the Kingdom of Jerusalem held him in high esteem. One of them, John of Ibelin emphasized that Aimery had governed both Cyprus and Jerusalem "well and wisely" until his death. + +Family + +Aimery's first wife, Eschiva of Ibelin, was the elder daughter of Baldwin of Ibelin, Lord of Mirabel and Ramleh, and Richelda of Beisan.

With Isidore of Miletus, he designed the Hagia Sophia for Justinian I. + +Life +Anthemius was one of the five sons of Stephanus of Tralles, a physician. His brothers were Dioscorus, Alexander, Olympius, and Metrodorus. Dioscorus followed his father's profession in Tralles; Alexander did so in Rome and became one of the most celebrated medical men of his time; Olympius became a noted lawyer; and Metrodorus worked as a grammarian in Constantinople. + +Anthemius was said to have annoyed his neighbor Zeno in two ways: first, by engineering a miniature earthquake by sending steam through leather tubes he had fixed among the joists and flooring of Zeno's parlor while he was entertaining friends and, second, by simulating thunder and lightning and flashing intolerable light into Zeno's eyes from a slightly hollowed mirror. In addition to his familiarity with steam, some dubious authorities credited Anthemius with a knowledge of gunpowder or other explosive compound. + +Mathematics +Anthemius was a capable mathematician. In the course of his treatise On Burning Mirrors, he intended to facilitate the construction of surfaces to reflect light to a single point, he described the string construction of the ellipse and assumed a property of ellipses not found in Apollonius of Perga's Conics: the equality of the angles subtended at a focus by two tangents drawn from a point. His work also includes the first practical use of the directrix: having given the focus and a double ordinate, he used the focus and directrix to obtain any number of points on a parabola. This work was later known to Arab mathematicians such as Alhazen. + +Eutocius's commentary on Apollonius's Conics was dedicated to Anthemius. + +Architecture + +As an architect, Anthemius is best known for his work designing the Hagia Sophia.

He endowed several church institutions, most prominently his family's Sorø Abbey. He was granted lands by the crown, and built the first fortification of the city that evolved into modern-day Copenhagen. His titles were passed on to his nephews Anders Sunesen and Peder Sunesen. He died in 1201, and was interred at Sorø Abbey. + +Early life +Absalon was born around 1128 near Sorø, Zealand. Due to his name being unusual in Denmark, it is speculated that he was baptized on the Danish "Absalon" name day, 30 October. He was the son of Asser Rig, a magnate of the Hvide clan from Fjenneslev on Zealand, and Inger Eriksdotter. He was also a kinsman of Archbishop Eskil of Lund. He grew up at the castle of his father, and was brought up alongside his older brother Esbern Snare and the young prince Valdemar, who later became King Valdemar I of Denmark. During the civil war following the death of Eric III of Denmark in 1146, Absalon travelled abroad to study theology in Paris, while Esbern fought for Valdemar's ascension to the throne. In Paris, he was influenced by the Gregorian Reform ideals of churchly independence from monarchical rule. He also befriended the canon William of Æbelholt at the Abbey of St Genevieve, whom he later made abbot of Eskilsø Abbey. + +Absalon first appears in Saxo Grammaticus's contemporary chronicle Gesta Danorum at the end of the civil war, in the brokering of the peace agreement between Sweyn III and Valdemar at St. Alban's Priory in Odense. He was a guest at the subsequent Roskilde banquet given in 1157 by Sweyn for his rivals Canute V and Valdemar. Both Absalon and Valdemar narrowly escaped assassination by Sweyn on this occasion, and escaped to Jutland, whither Sweyn followed them. Absalon probably did not take part in the following battle of Grathe Heath in 1157, where Sweyn was defeated and slain. This led to Valdemar ascending to the Danish throne. On Good Friday 1158, bishop died, and Absalon was eventually elected bishop of Roskilde on Zealand with the help of Valdemar, as the king's reward for Hvide family support. + +Bishop and advisor +Absalon was a close counsellor of Valdemar, and chief promoter of the Danish crusades against the Wends. During the Danish civil war, Denmark had been open to coastal raids by the Wends. It was Absalon's intention to clear the Baltic Sea of the Wendish pirates who inhabited its southern littoral zone, which was later called Pomerania. The pirates had raided the Danish coasts during the civil war of Sweyn III, Canute V, and Valdemar, to the point where at the accession of Valdemar one-third of Denmark lay wasted and depopulated. Absalon formed a guardian fleet, built coastal defenses, and led several campaigns against the Wends. He even advocated forgiving the earlier enemies of Valdemar, which helped stabilize Denmark internally. + +Wendish campaigns + +The first expedition against the Wends conducted by Absalon in person, set out in 1160. These expeditions were successful, but brought no lasting victories. What started out as mere retribution, eventually evolved into full-fledged campaigns of expansion with religious motives. In 1164 began twenty years of crusades against the Wends, sometimes with the help of German duke Henry the Lion, sometimes in opposition to him. + +In 1168 the chief Wendish fortress at Arkona in Rügen, containing the sanctuary of their god Svantevit, was conquered. The Wends agreed to accept Danish suzerainty and the Christian religion at the same time. From Arkona, Absalon proceeded by sea to Charenza, in the midst of Rügen, the political capital of the Wends and an all but impregnable stronghold. But the unexpected fall of Arkona had terrified the garrison, which surrendered unconditionally at the first appearance of the Danish ships. Absalon, with only Bishop Sweyn of Aarhus and twelve "housecarls", thereupon disembarked, passed between a double row of Wendish warriors, 6000 strong, along the narrow path winding among the morasses, to the gates of the fortress, and, proceeding to the temple of the seven-headed god Rugievit, caused the idol to be hewn down, dragged forth and burnt. The whole population of Garz was then baptized, and Absalon laid the foundations of twelve churches in the isle of Rügen. Rügen was then subjected to Absalon's Bishopric of Roskilde. + +The destruction of this chief sally-port of the Wendish pirates enabled Absalon to considerably reduce the Danish fleet. But he continued to keep a watchful eye over the Baltic, and in 1170 destroyed another pirate stronghold, farther eastward, at Dziwnów on the isle of Wolin. Absalon's last military exploit came in 1184, off Stralsund at Whitsun, when he soundly defeated a Pomeranian fleet that had attacked Denmark's vassal, Jaromar of Rügen. + +Policies +Absalon's main political goal was to free Denmark from entanglements with the Holy Roman Empire. Absalon reformed the Danish church organisation to closer match Holy See praxis, and worked to keep Denmark a close ally of the Holy See. However, during the schism between Pope Alexander III and Antipope Victor IV, Absalon stayed loyal to Valdemar even as he joined the Holy Roman Emperor Frederick Barbarossa in supporting Victor IV. This caused a split within the Danish church, as it possibly forced Eskil of Lund into exile around 1161, despite Abaslon's attempts to keep the Danish church united. It was contrary to Absalon's advice and warnings that Valdemar I rendered fealty to the emperor Frederick Barbarossa at Dole in 1162. When Valdemar returned to Denmark, he was convinced to strengthen the Danevirke fortifications at the German border, with the support of Absalon. + +Absalon built churches and monasteries, supporting international religious orders like the Cistercians and Augustinians, founding schools and doing his utmost to promote civilization and enlightenment. In 1162, Absalon transformed the Sorø Abbey of his family from Benedictine to Cistercian, granting it lands from his personal holdings. In 1167, Absalon was granted the land around the city of Havn (English: "Harbour"), and built there a castle for coastal defense against the Wends. Havn quickly expanded into one of Scandinavia's most important centers of trade, and eventually evolved into modern-day Copenhagen. It was also Absalon who held the first Danish Synod at Lund in 1167. He was interested in history and culture, and commissioned Saxo Grammaticus to write Gesta Danorum, a comprehensive chronicle of the history of the Danes. In 1171, Absalon issued the "Zealand church law" (), which reduced the number of Canonical Law offenses for which the church could fine the public, while instituting the tithe payment system. Violation of the law was specified as subject to a secular legal process. + +Archbishop of Lund +Archbishop Eskil returned from exile in 1167. Eskil agreed on canonizing Valdemar's father Knud Lavard in 1170, with Absalon assisting him at the feast. When Eskil stepped down as Archbishop of Lund in 1177, he chose Absalon as his successor. Absalon initially resisted the new position, as he did not want to lose his power position on Zealand, but complied with Papal orders to do so in 1178. By a unique Papal dispensation, Absalon was allowed to simultaneously maintain his post as Bishop of Roskilde. As the Archbishop of Lund, Absalon utilized ombudsmen from Zealand, demanded unfree labour from the peasantry, and instituted tithes. He was a harsh and effective ruler, who cleared all Orthodox Christian liturgical remnants in favour of Papal standards. A rebellion in the Scanian peasantry forced him to flee to Zealand in 1180, but he returned and subdued the Scanians with the help of Valdemar. + +Valdemar died in 1182 and was succeeded by his son, Canute VI, whom Absalon also served as counsellor. Under Canute VI, Absalon was the chief policymaker in Danish politics. Absalon kept his hostile attitude to the Holy Roman Empire. On the accession of Canute VI in 1182, an imperial ambassador arrived at Roskilde to get the new king to swear fealty to Frederick Barbarossa, but Absalon resolutely withstood him. + +Death +When Absalon retired from military service in 1184 at the age of fifty-seven, he resigned the command of fleets and armies to younger men, like Duke Valdemar, the later king Valdemar II. He instead confined himself to the administration of the Danish empire. In 1192, Absalon made his nephew his successor as Bishop of Roskilde, while his other nephew Anders Sunesen was named the chancellor of Canute VI. Absalon died at Sorø Abbey on 21 March 1201, 73 years old, with his last will granting his personal holdings to the Abbey, apart from Fjenneslev which went to Esbern Snarre. He had already given Copenhagen to the Bishopric of Roskilde. Absalon was interred at Sorø Abbey, and was succeeded as Archbishop of Lund by Anders Sunesen. + +Legacy + +Saxo Grammaticus' Gesta Danorum was not finished until after the death of Absalon, but Absalon was one of the chief heroic figures of the chronicle, which was to be the main source of knowledge about early Danish history. Absalon left a legacy as the foremost politician and churchfather of Denmark in the 12th century. Absalon was equally great as churchman, statesman, and warrior. His policy of expansion was to give Denmark the dominion of the Baltic for three generations. That he enjoyed warfare there can be no doubt; yet he was not like the ordinary fighting bishops of the Middle Ages, whose sole indication of their religious role was to avoid the shedding of blood by using a mace in battle instead of a sword. Absalon never neglected his ecclesiastical duties. + +In the 2000s, "Absalon" was adopted as the name for a class of Royal Danish Navy vessels, and the lead vessel of the class. HDMS Absalon (L16) and Esbern Snare (L17) were launched and commissioned by Denmark in 2004 and 2005. + +References + +Further reading + Saxo, Gesta Danorum, ed.

He was the chosen representative of Pope Urban II for the expedition to the Holy Land. Remembered for his martial prowess, he led knights and men into battle and fought beside them, particularly at the Battle of Dorylaeum and Siege of Antioch. Adhemar is said to have carried the Holy Lance in the Crusaders’ desperate breakout at Antioch on 28 June 1098, in which superior Islamic forces under the atabeg Kerbogha were routed, securing the city for the Crusaders. He died in 1098 due to illness. + +Life +Born around 1045 into the family of the Counts of Valentinois and elected Bishop of Le Puy around 1080, he was an advocate of the Gregorian Reform. Among his supporters were the future Pope Urban II and Raymond of Saint-Gilles, Count of Toulouse and the richest, most powerful nobleman in France. He was also said to have gone on pilgrimage to Jerusalem around 1086. He was the brother of William Hugh of Monteil, who was also a Crusader in the First Crusade. Adhemar most likely met Pope Urban II, when he visited Puy in August 1095. + +At the Council of Clermont in 1095, Adhemar showed great zeal for the crusade (there is evidence that Urban II had conferred with Adhemar before the council). Adhemar was named apostolic legate and appointed to lead the crusade by Pope Urban II on 27 November 1095. In part, Adhemar was selected to lead because he had already undertaken a pilgrimage to Jerusalem in 1086 and 1087. Following the announcement of the Crusade Adhemar spent the next year raising money and recruiting men. Departing on 15 August 1096, he accompanied Raymond of Toulouse and his army to the east. Whilst Raymond and the other leaders often quarrelled with each other over the leadership of the crusade, Adhemar was always recognized as the spiritual leader of the crusade and was widely respected by the majority of the Crusaders. + +During the leg of the trip from Durazzo to Constantinople, in the Valley of Pelagonia, Adhemar was set upon by a group of Pecheneg mercenaries, when he had wandered too far from the majority of the Crusader forces. The Pechenegs beat and robbed Adhemar, but began to fight among themselves over his belongings; Adhemar was saved by Crusader forces who had noticed the disturbance. Once the army had reached Thessalonica, Adhemar decided to stay there for some time, due to sickness, whilst the Crusader forces moved onward. Adhemar eventually was able to rejoin the Crusaders. + +Adhemar negotiated with Alexius I Comnenus at Constantinople, reestablished some discipline among the crusaders at Nicaea, fought a crucial role at the Battle of Dorylaeum and was largely responsible for sustaining morale during the siege of Antioch through various religious rites including fasting and special observances of holy days. One such time he did this, was after an earthquake during the siege of Antioch, he had the Crusaders fast for three days and had the priests and clergy perform mass and prayers. Adhemar also ordered the Crusaders to shave and wear a cross in an attempt to stop Crusaders from attacking one another by accident. After the capture of the city in June 1098 and the subsequent siege led by Kerbogha, Adhemar organized a procession through the streets and had the gates locked so that the Crusaders, many of whom had begun to panic, would be unable to leave the city. He was extremely skeptical of Peter Bartholomew's discovery in Antioch of the Holy Lance, especially because he knew such a relic already existed in Constantinople; however, he was willing to let the Crusader army believe it was real if it raised their morale. Adhemar was protected by a band of Crusaders led by Henry of Esch to preserve the (albeit suspect) relic. In June 1098 Adhemar fell prey to sickness and in the following months his condition would deteriorate. + +When Kerbogha was defeated, Adhemar organized a council in an attempt to settle the leadership disputes, but died on 1 August 1098, probably of typhus. Adhemar was buried in Antioch within the Basilica of St Peter. The disputes among the higher nobles went unsolved and the march to Jerusalem was delayed for months. However, the lower-class soldiers continued to think of Adhemar as a leader. Following his death, Adhemar reportedly appeared in several visions of various Crusaders. One of the first was reported by Peter Bartholomew who stated that Adhemar appeared to him stating that, due to his skepticism of the Holy Lance, he had spent a few days in hell and was only rescued because a candle had been burned in his memory, he had given a gift to the Shrine where the Holy Lance was kept, and due to the prayers of Bohemond. At the siege of Jerusalem, Peter Desiderius claimed that to have received a vision from Adhemar himself. Peter also claimed that, in this vision, Adhemar had instructed him to have the Crusaders fast and lead a procession around the Walls of Jerusalem. This was done and Jerusalem was taken by the Crusaders in 1099. Later, Stephen of Valence also claimed to have had visions featuring Adhemar in which Adhemar spoke to Stephen of several relics. Adhemar told Stephen great reverence should be given to the cross Adhemar had taken with him on the crusade. He also told Stephen how the Holy Lance should be treated and told Stephen to give Stephen's ring to Count Raymond. He told Stephen that, through this ring, Count Raymond would be able to call upon the power of Mary. + +References + +Sources + +Murray, Alan V., "The Army of Godfrey of Bouillon, 1096–1099: Structure and Dynamics of a Contingent on the First Crusade" (PDF), Revue belge de philologie et d'histoire, 1992 +Runciman, Steven, A History of the Crusades, Volume I: The First Crusade and the Foundation of the Kingdom of Jerusalem, Cambridge University Press, Cambridge, 1951 +Riley-Smith, The First Crusaders, 1095–1131, Cambridge University Press, Cambridge, 1997 +Edgington, Susan, Albert of Aachen: Historia Ierosolimitana, History of the Journey to Jerusalem, Clarendon Press, 2007 (available on Google Books) + +External links + Medieval Sourcebook: Speech by Urban II at Council of Clermont, 1095 (Five versions of the Speech) + +Christians of the First Crusade +11th-century French Roman Catholic bishops +Bishops of Le Puy-en-Velay +1098 deaths +Year of birth unknown +1040s births +Alphonse or Alfonso (11 November 122021 August 1271) was the count of Poitou from 1225 and count of Toulouse (as such called Alphonse II) from 1249. As count of Toulouse, he also governed the Marquisate of Provence. + +Birth and early life +Born at Poissy, Alphonse was a son of King Louis VIII of France and Blanche of Castile. He was a younger brother of King Louis IX of France and an older brother of Count Charles I of Anjou. In 1229, his mother, who was regent of France, forced the Treaty of Paris on Count Raymond VII of Toulouse after his rebellion. It stipulated that a brother of King Louis was to marry Joan, daughter of Raymond VII of Toulouse, and so in 1237 Alphonse married her. Since she was Raymond's only child, they became rulers of Toulouse at Raymond's death in 1249. + +By the terms of his father's will Alphonse received an appanage of Poitou and Auvergne. To enforce this Louis IX won the battle of Taillebourg in the Saintonge War together with Alphonse against a revolt allied with King Henry III of England, who also participated in the battle. + +Crusades +Alphonse took part in two crusades with his brother, St Louis, in 1248 (the Seventh Crusade) and in 1270 (the Eighth Crusade). For the first of these, he raised a large sum and a substantial force, arriving in Damietta on 24 October 1249, after the town had already been captured. He sailed for home on 10 August 1250. His father-in-law had died while he was away, and he went directly to Toulouse to take possession. There was some resistance to his accession as count, which was suppressed with the help of his mother Blanche of Castile who was acting as regent in the absence of Louis IX. + +Later life +In 1252, on the death of his mother, Blanche of Castile, Alphonse was joint regent with Charles of Anjou until the return of Louis IX. During that time he took a great part in the campaigns and negotiations which led to the Treaty of Paris in 1259, under which King Henry III of England recognized his loss of continental territory to France (including Normandy, Maine, Anjou, and Poitou) in exchange for France withdrawing support from English rebels. + +Aside from the crusades, Alphonse stayed primarily in Paris, governing his estates by officials, inspectors who reviewed the officials' work, and a constant stream of messages. His main work was on his own estates. There he repaired the evils of the Albigensian war and made a first attempt at administrative centralization, thus preparing the way for union with the crown. On 8 October 1268, Alphonse had all Jews throughout his lands arrested and their property confiscated. + +When Louis IX formed the Eighth Crusade, Alphonse again raised a large sum of money and accompanied his brother. This time, however, he did not return to France, dying while on his way back, at Savona in Italy, on 21 August 1271. + +Death and legacy +Alphonse's death without heirs raised some questions as to the succession to his lands. One possibility was that they should revert to the crown, another that they should be redistributed to his family. The latter was claimed by Charles of Anjou, but in 1283 Parlement decided that the County of Toulouse should revert to the crown, if there were no male heirs. Alphonse's wife Joan (who died four days after Alphonse) had attempted to dispose of some of her inherited lands in her will. Joan was the only surviving child and heiress of Raymond VII, Count of Toulouse, Duke of Narbonne, and Marquis of Provence, so under Provençal and French law, the lands should have gone to her nearest male relative. But, her will was invalidated by Parlement in 1274. One specific bequest in Alphonse's will, giving his wife's lands in the Comtat Venaissin to the Holy See, was allowed, and it became a Papal territory, a status that it retained until 1791. + +See also + Abraham of Aragon + +References + +Sources + + + +|- + +|- + +1220 births +1271 deaths +People from Poissy +Counts of Toulouse +Counts of Poitiers +Christians of the Seventh Crusade +Christians of the Eighth Crusade +13th-century peers of France +Children of Louis VIII of France +Prisoners and detainees of the Abbasid Caliphate +Sons of kings +Alfonso Jordan, also spelled Alfons Jordan or Alphonse Jourdain (1103–1148), was the Count of Tripoli (1105–09), Count of Rouergue (1109–48) and Count of Toulouse, Margrave of Provence and Duke of Narbonne (1112–48). + +Life +Alfonso was the son of Raymond IV of Toulouse by his third wife, Elvira of Castile. He was born in the castle of Mont Pèlerin in Tripoli while his father was on the First Crusade. He was given the name "Jourdain" after being baptised in the Jordan River. +Alfonso's father died when he was two years old and he remained under the guardianship of his cousin, William Jordan, Count of Cerdagne, until he was five. He was then taken to Europe, where his half-brother Bertrand had given him the county of Rouergue. Upon Bertrand's death in 1112, Alfonso succeeded to the county of Toulouse and marquisate of Provence. + +In 1114, Duke William IX of Aquitaine, who claimed Toulouse by right of his wife Philippa, daughter of Count William IV, invaded the county and conquered it. Alfonso recovered a part in 1119, but he was not in full control until 1123. When at last successful, he was excommunicated by Pope Callixtus II for having damaged the abbey of Saint-Gilles and assaulting the monks. + +Alfonso next had to fight for his rights in Provence against Count Raymond Berengar III of Barcelona. Not until September 1125 did their war end in "peace and concord" (pax et concordia). At this stage, Alfonso was master of the regions lying between the Pyrenees and the Alps, the Auvergne and the sea. His ascendancy was, according to one commentator, an unmixed good to the country, for during a period of fourteen years art and industry flourished. + +In March 1126, Alfonso was at the court of Alfonso VII of León when he acceded to the throne. According to the Chronica Adefonsi imperatoris, Alfonso and Suero Vermúdez took the city of León from opposition magnates and handed it over to Alfonso VII. Among those who may have accompanied Alfonso on one of his many extended stays in Spain was the troubadour Marcabru. + +By 1132, Alfonso was embroiled in a succession war over the county of Melgueil against Berenguer Ramon, Count of Provence. This brief conflict was resolved with Alfonso's defeat and Berenguer marrying Beatrice, heiress of Melgueil. + +Alfonso seized the viscounty of Narbonne in 1134, and ruled it during the minority of the Viscountess Ermengarde, only restoring it to her in 1143. +In 1141 King Louis VII pressed the claim of Philippa on behalf of his wife, Eleanor of Aquitaine, even besieging Toulouse, but without result. +That same year Alfonso Jordan was again in Spain, making a pilgrimage to Saint James of Compostela, when he proposed a peace between the king of León and García VI of Navarre, which became the basis for subsequent negotiations. + +In 1144, Alfonso again incurred the displeasure of the church by siding with the citizens of Montpellier against their lord. +In 1145, Bernard of Clairvaux addressed a letter to him full of concern about a heretic named Henry in the diocese of Toulouse. Bernard even went there to preach against the heresy, an early expression of Catharism. A second time he was excommunicated; but in 1146 he took the cross (i.e., vowed to go on crusade) at a meeting in Vézelay called by Louis VII. In August 1147, he embarked for the near east on the Second Crusade. +He lingered on the way in Italy and probably in Constantinople, where he may have met the Emperor Manuel I. + +Alfonso finally arrived at Acre in 1148. He died at Caesarea, which was followed by accusations of poisoning, levelled against either Eleanor of Aquitaine, wife of Louis VII of France, or Melisende, the mother of King Baldwin III of Jerusalem, who may have wanted to eliminate him as a rival to her brother-in-law Raymond II. + +Alfonso and Faydiva d'Uzès had: + + Raymond, who succeeded him + Alphonse + Faydiva (died 1154), married to Count Humbert III of Savoy + Agnes (died 1187) + Laurentia, who married Count Bernard III of Comminges + +He also had an illegitimate son, Bertrand. + +Notes + +Sources + +156 + + + + + + + +1103 births +1148 deaths +People temporarily excommunicated by the Catholic Church +Counts of Tripoli +Counts of Toulouse +Dukes of Narbonne +Margraves of Provence +Occitan nobility +House of Rouergue +Christians of the Second Crusade +Ambroise, sometimes Ambroise of Normandy, (flourished ) was a Norman poet and chronicler of the Third Crusade, author of a work called , which describes in rhyming Old French verse the adventures of as a crusader.

He speaks as an eyewitness of the king's doings at Messina, in Cyprus, at the siege of Acre, and in the abortive campaign which followed the capture of that city. + +Ambroise is surprisingly accurate in his chronology; though he did not complete his work before 1195, it is evidently founded upon notes which he had taken in the course of his pilgrimage. He shows no greater political insight than we should expect from his position; but relates what he had seen and heard with a naïve vivacity which compels attention. He is by no means an impartial source: he is prejudiced against the Saracens, against the French, and against all the rivals or enemies of his master, including the Polein party which supported Conrad of Montferrat against Guy of Lusignan. He is rather to be treated as a biographer than as a historian of the Crusade in its broader aspects. Nonetheless he is an interesting primary source for the events of the years 1190–1192 in the Kingdom of Jerusalem. + +Books 2–6 of the Itinerarium Regis Ricardi, a Latin prose narrative of the same events apparently compiled by Richard, a canon of Holy Trinity, London, are closely related to Ambroise's poem.

Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. + +Art Deco got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined the styles of early 20th century Modernist avant-garde, with the fine craftsmanship and rich materials of French historic design, but also sometimes with motifs taken from non-Western cultures. From its outset, Art Deco was influenced by the bold geometric forms of Cubism and the Vienna Secession; the bright colours of Fauvism and of the Ballets Russes; the updated craftsmanship of the furniture of the eras of Louis XVI and Louis Philippe I; and the exoticized styles of China, Japan, India, Persia, ancient Egypt and Maya art. + +During its heyday, Art Deco represented luxury, glamour, exuberance, and faith in social and technological progress. The movement featured rare and expensive materials, such as ebony and ivory, and exquisite craftsmanship. The Empire State Building, Chrysler Building, and other skyscrapers of New York City built during the 1920s and 1930s are monuments to the style. + +In the 1930s, during the Great Depression, Art Deco gradually became more subdued, paving the way for the International Style and Mid-century modern. New materials arrived, including chrome plating, stainless steel and plastic. A sleeker form of the style, called Streamline Moderne, appeared in the 1930s, featuring curving forms and smooth, polished surfaces. Art Deco was a truly international style, but its dominance ended with the beginning of World War II and the rise of the strictly functional and unadorned styles of modern architecture and the International Style of architecture that followed. + +Etymology +Art Deco took its name, short for , from the Exposition Internationale des Arts Décoratifs et Industriels Modernes held in Paris in 1925, though the diverse styles that characterised it had already appeared in Paris and Brussels before World War I. + +Arts décoratifs was first used in France in 1858 in the Bulletin de la Société française de photographie. In 1868, the Le Figaro newspaper used the term objets d'art décoratifs for objects for stage scenery created for the Théâtre de l'Opéra. In 1875, furniture designers, textile, jewellers, glass-workers, and other craftsmen were officially given the status of artists by the French government. In response, the École royale gratuite de dessin (Royal Free School of Design), founded in 1766 under King Louis XVI to train artists and artisans in crafts relating to the fine arts, was renamed the École nationale des arts décoratifs (National School of Decorative Arts). It took its present name, ENSAD (École nationale supérieure des arts décoratifs), in 1927. + +At the 1925 Exposition, architect Le Corbusier wrote a series of articles about the exhibition for his magazine L'Esprit Nouveau, under the title "1925 EXPO. ARTS. DÉCO.", which were combined into a book, L'art décoratif d'aujourd'hui (Decorative Art Today). The book was a spirited attack on the excesses of the colourful, lavish objects at the Exposition, and on the idea that practical objects such as furniture should not have any decoration at all; his conclusion was that "Modern decoration has no decoration". + +The actual term art déco did not appear in print until 1966, in the title of the first modern exhibition on the subject, held by the Museum of Decorative Arts in Paris, Les Années 25 : Art déco, Bauhaus, Stijl, Esprit nouveau, which covered a variety of major styles in the 1920s and 1930s. The term was then used in a 1966 newspaper article by Hillary Gelson in The Times (London, 12 November), describing the different styles at the exhibit. + +Art Deco gained currency as a broadly applied stylistic label in 1968 when historian Bevis Hillier published the first major academic book on it, Art Deco of the 20s and 30s. He noted that the term was already being used by art dealers, and cites The Times (2 November 1966) and an essay named Les Arts Déco in Elle magazine (November 1967) as examples. In 1971, he organized an exhibition at the Minneapolis Institute of Arts, which he details in his book The World of Art Deco. + +It's also important to mention that, in its time, Art Deco was not only tagged with other names, like style moderne, Moderne, modernistic or style contemporain, but it was also not recognized at the theoretical level as a distinct and homogenous style. + +Origins + +Society of Decorative Artists (1901–1945) +The emergence of Art Deco was closely connected with the rise in status of decorative artists, who until late in the 19th century were considered simply artisans. The term had been invented in 1875, giving the designers of furniture, textiles, and other decoration official status. The Société des artistes décorateurs (Society of Decorative Artists), or SAD, was founded in 1901, and decorative artists were given the same rights of authorship as painters and sculptors. A similar movement developed in Italy. The first international exhibition devoted entirely to the decorative arts, the Esposizione Internazionale d'Arte Decorativa Moderna, was held in Turin in 1902. Several new magazines devoted to decorative arts were founded in Paris, including Arts et décoration and L'Art décoratif moderne. Decorative arts sections were introduced into the annual salons of the Sociéte des artistes français, and later in the Salon d'Automne. French nationalism also played a part in the resurgence of decorative arts, as French designers felt challenged by the increasing exports of less expensive German furnishings. In 1911, SAD proposed a major new international exposition of decorative arts in 1912. No copies of old styles would be permitted, only modern works. The exhibit was postponed until 1914; and then, because of the war, until 1925, when it gave its name to the whole family of styles known as "Déco". + +Parisian department stores and fashion designers also played an important part in the rise of Art Deco. Prominent businesses such as silverware firm Christofle, glass designer René Lalique, and the jewellers Louis Cartier and Boucheron began designing products in more modern styles. Beginning in 1900, department stores recruited decorative artists to work in their design studios. The decoration of the 1912 Salon d'Automne was entrusted to the department store Printemps, and that year it created its own workshop, Primavera. By 1920 Primavera employed more than 300 artists, whose styles ranged from updated versions of Louis XIV, Louis XVI, and especially Louis Philippe furniture made by Louis Süe and the Primavera workshop, to more modern forms from the workshop of the Au Louvre department store. Other designers, including Émile-Jacques Ruhlmann and Paul Follot, refused to use mass production, insisting that each piece be made individually. The early Art Deco style featured luxurious and exotic materials such as ebony, ivory and silk, very bright colours and stylized motifs, particularly baskets and bouquets of flowers of all colours, giving a modernist look. + +Vienna Secession and Wiener Werkstätte (1897–1912) +The architects of the Vienna Secession (formed 1897), especially Josef Hoffmann, had a notable influence on Art Deco. His Stoclet Palace, in Brussels (1905–1911), was a prototype of the Art Deco style, featuring geometric volumes, symmetry, straight lines, concrete covered with marble plaques, finely-sculpted ornament, and lavish interiors, including mosaic friezes by Gustav Klimt. Hoffmann was also a founder of the Wiener Werkstätte (1903–1932), an association of craftsmen and interior designers working in the new style. This became the model for the Compagnie des arts français, created in 1919, which brought together André Mare, and Louis Süe, the first leading French Art Deco designers and decorators. + +New materials and technologies +New materials and technologies, especially reinforced concrete, were key to the development and appearance of Art Deco. The first concrete house was built in 1853 in the Paris suburbs by François Coignet. In 1877 Joseph Monier introduced the idea of strengthening the concrete with a mesh of iron rods in a grill pattern. In 1893 Auguste Perret built the first concrete garage in Paris, then an apartment building, house, then, in 1913, the Théâtre des Champs-Élysées. The theatre was denounced by one critic as the "Zeppelin of Avenue Montaigne", an alleged Germanic influence, copied from the Vienna Secession. Thereafter, the majority of Art Deco buildings were made of reinforced concrete, which gave greater freedom of form and less need for reinforcing pillars and columns. Perret was also a pioneer in covering the concrete with ceramic tiles, both for protection and decoration. The architect Le Corbusier first learned the uses of reinforced concrete working as a draftsman in Perret's studio. + +Other new technologies that were important to Art Deco were new methods in producing plate glass, which was less expensive and allowed much larger and stronger windows, and for mass-producing aluminium, which was used for building and window frames and later, by Corbusier, Warren McArthur, and others, for lightweight furniture. + +Théâtre des Champs-Élysées (1910–1913) + +The Théâtre des Champs-Élysées (1910–1913), by Auguste Perret, was the first landmark Art Deco building completed in Paris. Previously, reinforced concrete had been used only for industrial and apartment buildings, Perret had built the first modern reinforced-concrete apartment building in Paris on rue Benjamin Franklin in 1903–04. Henri Sauvage, another important future Art Deco architect, built another in 1904 at 7, rue Trétaigne (1904). From 1908 to 1910, the 21-year-old Le Corbusier worked as a draftsman in Perret's office, learning the techniques of concrete construction. Perret's building had clean rectangular form, geometric decoration and straight lines, the future trademarks of Art Deco. The décor of the theatre was also revolutionary; the façade was decorated with high reliefs by Antoine Bourdelle, a dome by Maurice Denis, paintings by Édouard Vuillard, and an Art Deco curtain by Ker-Xavier Roussel. The theatre became the venue for many of the first performances of the Ballets Russes. Perret and Sauvage became the leading Art Deco architects in Paris in the 1920s. + +Salon d'Automne (1903–1914) + +At its birth between 1910 and 1914, Art Deco was an explosion of colours, featuring bright and often clashing hues, frequently in floral designs, presented in furniture upholstery, carpets, screens, wallpaper and fabrics. Many colourful works, including chairs and a table by Maurice Dufrêne and a bright Gobelin carpet by Paul Follot were presented at the 1912 Salon des artistes décorateurs. In 1912–1913 designer Adrien Karbowsky made a floral chair with a parrot design for the hunting lodge of art collector Jacques Doucet. The furniture designers Louis Süe and André Mare made their first appearance at the 1912 exhibit, under the name of the Atelier français, combining polychromatic fabrics with exotic and expensive materials, including ebony and ivory. After World War I, they became one of the most prominent French interior design firms, producing the furniture for the first-class salons and cabins of the French transatlantic ocean liners. + +The vivid hues of Art Deco came from many sources, including the exotic set designs by Léon Bakst for the Ballets Russes, which caused a sensation in Paris just before World War I. Some of the colours were inspired by the earlier Fauvism movement led by Henri Matisse; others by the Orphism of painters such as Sonia Delaunay; others by the movement known as Les Nabis, and in the work of symbolist painter Odilon Redon, who designed fireplace screens and other decorative objects. Bright shades were a feature of the work of fashion designer Paul Poiret, whose work influenced both Art Deco fashion and interior design. + +Cubism + +The art movement known as Cubism appeared in France between 1907 and 1912, influencing the development of Art Deco. In Art Deco Complete: The Definitive Guide to the Decorative Arts of the 1920s and 1930s Alastair Duncan writes "Cubism, in some bastardized form or other, became the lingua franca of the era's decorative artists." The Cubists, themselves under the influence of Paul Cézanne, were interested in the simplification of forms to their geometric essentials: the cylinder, the sphere, the cone. + +In 1912, the artists of the Section d'Or exhibited works considerably more accessible to the general public than the analytical Cubism of Picasso and Braque. The Cubist vocabulary was poised to attract fashion, furniture and interior designers. + +The 1912 writings of André Vera, Le Nouveau style, published in the journal L'Art décoratif, expressed the rejection of Art Nouveau forms (asymmetric, polychrome and picturesque) and called for simplicité volontaire, symétrie manifeste, l'ordre et l'harmonie, themes that would eventually become common within Art Deco; though the Deco style was often extremely colourful and often complex. + +In the Art Décoratif section of the 1912 Salon d'Automne, an architectural installation was exhibited known as La Maison Cubiste. The façade was designed by Raymond Duchamp-Villon. The décor of the house was by André Mare. La Maison Cubiste was a furnished installation with a façade, a staircase, wrought iron banisters, a bedroom, a living room—the Salon Bourgeois, where paintings by Albert Gleizes, Jean Metzinger, Marie Laurencin, Marcel Duchamp, Fernand Léger and Roger de La Fresnaye were hung. Thousands of spectators at the salon passed through the full-scale model. + +The façade of the house, designed by Duchamp-Villon, was not very radical by modern standards; the lintels and pediments had prismatic shapes, but otherwise the façade resembled an ordinary house of the period. For the two rooms, Mare designed the wallpaper, which featured stylized roses and floral patterns, along with upholstery, furniture and carpets, all with flamboyant and colourful motifs. It was a distinct break from traditional décor. The critic Emile Sedeyn described Mare's work in the magazine Art et Décoration: "He does not embarrass himself with simplicity, for he multiplies flowers wherever they can be put. The effect he seeks is obviously one of picturesqueness and gaiety. He achieves it." The Cubist element was provided by the paintings. The installation was attacked by some critics as extremely radical, which helped make for its success. This architectural installation was subsequently exhibited at the 1913 Armory Show, New York City, Chicago and Boston. Thanks largely to the exhibition, the term "Cubist" began to be applied to anything modern, from women's haircuts to clothing to theater performances." + +The Cubist influence continued within Art Deco, even as Deco branched out in many other directions. In 1927, Cubists Joseph Csaky, Jacques Lipchitz, Louis Marcoussis, Henri Laurens, the sculptor Gustave Miklos, and others collaborated in the decoration of a Studio House, rue Saint-James, Neuilly-sur-Seine, designed by the architect Paul Ruaud and owned by the French fashion designer Jacques Doucet, also a collector of Post-Impressionist art by Henri Matisse and Cubist paintings (including Les Demoiselles d'Avignon, which he bought directly from Picasso's studio). Laurens designed the fountain, Csaky designed Doucet's staircase, Lipchitz made the fireplace mantel, and Marcoussis made a Cubist rug. + +Besides the Cubist artists, Doucet brought in other Deco interior designers to help in decorating the house, including Pierre Legrain, who was in charge of organizing the decoration, and Paul Iribe, Marcel Coard, André Groult, Eileen Gray and Rose Adler to provide furniture. The décor included massive pieces made of macassar ebony, inspired by African art, and furniture covered with Morocco leather, crocodile skin and snakeskin, and patterns taken from African designs. + +Cubism's adumbrated geometry became coin of the realm in the 1920s. Art Deco's development of Cubism's selective geometry into a wider array of shapes carried Cubism as a pictorial taxonomy to a much broader audience and wider appeal. (Richard Harrison Martin, Metropolitan Museum of Art) + +Influences + +Pre-WW1 past + +Art Deco was not a single style, but a collection of different and sometimes contradictory styles. In architecture, Art Deco was the successor to and reaction against Art Nouveau, a style which flourished in Europe between 1895 and 1900, and coexisted with the Beaux-Arts and neoclassical that were predominant in European and American architecture. In 1905 Eugène Grasset wrote and published Méthode de Composition Ornementale, Éléments Rectilignes, in which he systematically explored the decorative (ornamental) aspects of geometric elements, forms, motifs and their variations, in contrast with (and as a departure from) the undulating Art Nouveau style of Hector Guimard, so popular in Paris a few years earlier. Grasset stressed the principle that various simple geometric shapes like triangles and squares are the basis of all compositional arrangements. The reinforced-concrete buildings of Auguste Perret and Henri Sauvage, and particularly the Théâtre des Champs-Élysées, offered a new form of construction and decoration which was copied worldwide. + +Ancient and non-European civilizations + +In decoration, many different styles were borrowed and used by Art Deco. They included pre-modern art from around the world and observable at the Musée du Louvre, Musée de l'Homme and the Musée national des Arts d'Afrique et d'Océanie. There was also popular interest in archaeology due to excavations at Pompeii, Troy, and the tomb of the 18th dynasty Pharaoh Tutankhamun. Artists and designers integrated motifs from ancient Egypt, Africa, Mesopotamia, Greece, Rome, Asia, Mesoamerica and Oceania with Machine Age elements. + +Early 20th century avant-garde movements + +Other styles borrowed included Futurism, Orphism, Functionalism, and Modernism in general. Cubism discovers its decorative potential within the Art Deco aesthetic, when transposed from the canvas onto a textile material or wallpaper. Sonia Delaunay conceives her dress models in an abstract and geometric style, "as live paintings or sculptures of living forms". Cubist-like designs are created by Louis Barrilet in the stained-glass windows of the American bar at the Atrium Casino in Dax (1926), but also including names of fashionable cocktails. In architecture, the clear contrast between horizontal and vertical volumes, specific both to Russian Constructivism and the Frank Lloyd Wright-Willem Marinus Dudok line, becomes a common device in articulating Art Deco façades, from individual homes and tenement buildings to cinemas or oil stations. Art Deco also used the clashing colours and designs of Fauvism, notably in the work of Henri Matisse and André Derain, inspired the designs of art deco textiles, wallpaper, and painted ceramics. It took ideas from the high fashion vocabulary of the period, which featured geometric designs, chevrons, zigzags, and stylized bouquets of flowers. It was influenced by discoveries in Egyptology, and growing interest in the Orient and in African art. From 1925 onwards, it was often inspired by a passion for new machines, such as airships, automobiles and ocean liners, and by 1930 this influence resulted in the style called Streamline Moderne. + +Style of luxury and modernity + +Art Deco was associated with both luxury and modernity; it combined very expensive materials and exquisite craftsmanship put into modernistic forms. Nothing was cheap about Art Deco: pieces of furniture included ivory and silver inlays, and pieces of Art Deco jewellery combined diamonds with platinum, jade, coral and other precious materials. The style was used to decorate the first-class salons of ocean liners, deluxe trains, and skyscrapers. It was used around the world to decorate the great movie palaces of the late 1920s and 1930s. Later, after the Great Depression, the style changed and became more sober. + +A good example of the luxury style of Art Deco is the boudoir of the fashion designer Jeanne Lanvin, designed by Armand-Albert Rateau (1882–1938) made between 1922 and 1925. It was located in her house at 16 rue Barbet de Jouy, in Paris, which was demolished in 1965. The room was reconstructed in the Museum of Decorative Arts in Paris. The walls are covered with moulded lambris below sculpted bas-reliefs in stucco. The alcove is framed with columns of marble on bases and a plinth of sculpted wood. The floor is of white and black marble, and in the cabinets decorative objects are displayed against a background of blue silk. Her bathroom had a tub and washstand made of sienna marble, with a wall of carved stucco and bronze fittings. + +By 1928 the style had become more comfortable, with deep leather club chairs. The study designed by the Paris firm of Alavoine for an American businessman in 1928–30, is now in the Brooklyn Museum. + +By the 1930s, the style had been somewhat simplified, but it was still extravagant. In 1932 the decorator Paul Ruaud made the Glass Salon for Suzanne Talbot. It featured a serpentine armchair and two tubular armchairs by Eileen Gray, a floor of mat silvered glass slabs, a panel of abstract patterns in silver and black lacquer, and an assortment of animal skins. + +International Exhibition of Modern Decorative and Industrial Arts (1925) + +The event that marked the zenith of the style and gave it its name was the International Exhibition of Modern Decorative and Industrial Arts which took place in Paris from April to October in 1925. This was officially sponsored by the French government, and covered a site in Paris of 55 acres, running from the Grand Palais on the right bank to Les Invalides on the left bank, and along the banks of the Seine. The Grand Palais, the largest hall in the city, was filled with exhibits of decorative arts from the participating countries. There were 15,000 exhibitors from twenty different countries, including Austria, Belgium, Czechoslovakia, Denmark, Great Britain, Italy, Japan, the Netherlands, Poland, Spain, Sweden, and the new Soviet Union. Germany was not invited because of tensions after the war; The United States, misunderstanding the purpose of the exhibit, declined to participate. The event was visited by sixteen million people during its seven-month run. The rules of the exhibition required that all work be modern; no historical styles were allowed. The main purpose of the Exhibit was to promote the French manufacturers of luxury furniture, porcelain, glass, metalwork, textiles, and other decorative products. To further promote the products, all the major Paris department stores, and major designers had their own pavilions. The Exposition had a secondary purpose in promoting products from French colonies in Africa and Asia, including ivory and exotic woods. + +The Hôtel du Collectionneur was a popular attraction at the Exposition; it displayed the new furniture designs of Emile-Jacques Ruhlmann, as well as Art Deco fabrics, carpets, and a painting by Jean Dupas. The interior design followed the same principles of symmetry and geometric forms which set it apart from Art Nouveau, and bright colours, fine craftsmanship rare and expensive materials which set it apart from the strict functionality of the Modernist style. While most of the pavilions were lavishly decorated and filled with hand-made luxury furniture, two pavilions, those of the Soviet Union and Pavilion de L'Esprit Nouveau, built by the magazine of that name run by Le Corbusier, were built in an austere style with plain white walls and no decoration; they were among the earliest examples of modernist architecture. + +Late Art Deco + +In 1925, two different competing schools coexisted within Art Deco: the traditionalists, who had founded the Society of Decorative Artists; included the furniture designer Emile-Jacques Ruhlmann, Jean Dunand, the sculptor Antoine Bourdelle, and designer Paul Poiret; they combined modern forms with traditional craftsmanship and expensive materials. On the other side were the modernists, who increasingly rejected the past and wanted a style based upon advances in new technologies, simplicity, a lack of decoration, inexpensive materials, and mass production. The modernists founded their own organisation, The French Union of Modern Artists, in 1929. Its members included architects Pierre Chareau, Francis Jourdain, Robert Mallet-Stevens, Corbusier, and, in the Soviet Union, Konstantin Melnikov; the Irish designer Eileen Gray; the French designer Sonia Delaunay; and the jewellers Georges Fouquet and Jean Puiforcat. They fiercely attacked the traditional art deco style, which they said was created only for the wealthy, and insisted that well-constructed buildings should be available to everyone, and that form should follow function. The beauty of an object or building resided in whether it was perfectly fit to fulfil its function. Modern industrial methods meant that furniture and buildings could be mass-produced, not made by hand. + +The Art Deco interior designer Paul Follot defended Art Deco in this way: "We know that man is never content with the indispensable and that the superfluous is always needed...If not, we would have to get rid of music, flowers, and perfumes..!" However, Le Corbusier was a brilliant publicist for modernist architecture; he stated that a house was simply "a machine to live in", and tirelessly promoted the idea that Art Deco was the past and modernism was the future. Le Corbusier's ideas were gradually adopted by architecture schools, and the aesthetics of Art Deco were abandoned. The same features that made Art Deco popular in the beginning, its craftsmanship, rich materials and ornament, led to its decline. The Great Depression that began in the United States in 1929, and reached Europe shortly afterwards, greatly reduced the number of wealthy clients who could pay for the furnishings and art objects. In the Depression economic climate, few companies were ready to build new skyscrapers. Even the Ruhlmann firm resorted to producing pieces of furniture in series, rather than individual hand-made items. The last buildings built in Paris in the new style were the Museum of Public Works by Auguste Perret (now the French Economic, Social and Environmental Council), the Palais de Chaillot by Louis-Hippolyte Boileau, Jacques Carlu and Léon Azéma, and the Palais de Tokyo of the 1937 Paris International Exposition; they looked out at the grandiose pavilion of Nazi Germany, designed by Albert Speer, which faced the equally grandiose socialist-realist pavilion of Stalin's Soviet Union. + +After World War II, the dominant architectural style became the International Style pioneered by Le Corbusier, and Mies van der Rohe. A handful of Art Deco hotels were built in Miami Beach after World War II, but elsewhere the style largely vanished, except in industrial design, where it continued to be used in automobile styling and products such as jukeboxes. In the 1960s, it experienced a modest academic revival, thanks in part to the writings of architectural historians such as Bevis Hillier. In the 1970s efforts were made in the United States and Europe to preserve the best examples of Art Deco architecture, and many buildings were restored and repurposed. Postmodern architecture, which first appeared in the 1980s, like Art Deco, often includes purely decorative features. Deco continues to inspire designers, and is often used in contemporary fashion, jewellery, and toiletries. + +Painting + +There was no section set aside for painting at the 1925 Exposition. Art deco painting was by definition decorative, designed to decorate a room or work of architecture, so few painters worked exclusively in the style, but two painters are closely associated with Art Deco. Jean Dupas painted Art Deco murals for the Bordeaux Pavilion at the 1925 Decorative Arts Exposition in Paris, and also painted the picture over the fireplace in the Maison du Collectionneur exhibit at the 1925 Exposition, which featured furniture by Ruhlmann and other prominent Art Deco designers. His murals were also prominent in the décor of the French ocean liner SS Normandie. His work was purely decorative, designed as a background or accompaniment to other elements of the décor. + +The other painter closely associated with the style is Tamara de Lempicka. Born in Poland, she emigrated to Paris after the Russian Revolution. She studied under Maurice Denis and André Lhote, and borrowed many elements from their styles. She painted portraits in a realistic, dynamic and colourful Art Deco style. + +In the 1930s a dramatic new form of Art Deco painting appeared in the United States. During the Great Depression, the Federal Art Project of the Works Progress Administration was created to give work to unemployed artists. Many were given the task of decorating government buildings, hospitals and schools. There was no specific art deco style used in the murals; artists engaged to paint murals in government buildings came from many different schools, from American regionalism to social realism; they included Reginald Marsh, Rockwell Kent and the Mexican painter Diego Rivera. The murals were Art Deco because they were all decorative and related to the activities in the building or city where they were painted: Reginald Marsh and Rockwell Kent both decorated U.S. postal buildings, and showed postal employees at work while Diego Rivera depicted automobile factory workers for the Detroit Institute of Arts. Diego Rivera's mural Man at the Crossroads (1933) for 30 Rockefeller Plaza featured an unauthorized portrait of Lenin. When Rivera refused to remove Lenin, the painting was destroyed and a new mural was painted by the Spanish artist Josep Maria Sert. + +Sculpture + +Monumental and public sculpture + +Sculpture was a very common and integral feature of Art Deco architecture. In France, allegorical bas-reliefs representing dance and music by Antoine Bourdelle decorated the earliest Art Deco landmark in Paris, the Théâtre des Champs-Élysées, in 1912. The 1925 Exposition had major sculptural works placed around the site, pavilions were decorated with sculptural friezes, and several pavilions devoted to smaller studio sculpture. In the 1930s, a large group of prominent sculptors made works for the 1937 at Chaillot. Alfred Janniot made the relief sculptures on the façade of the Palais de Tokyo. The Musée d'Art Moderne de la Ville de Paris, and the esplanade in front of the Palais de Chaillot, facing the Eiffel Tower, was crowded with new statuary by Charles Malfray, Henry Arnold, and many others. + +Public art deco sculpture was almost always representational, usually of heroic or allegorical figures related to the purpose of the building or room. The themes were usually selected by the patrons, not the artist. Abstract sculpture for decoration was extremely rare. + +In the United States, the most prominent Art Deco sculptor for public art was Paul Manship, who updated classical and mythological subjects and themes in an Art Deco style. His most famous work was the statue of Prometheus at Rockefeller Center in New York City, a 20th-century adaptation of a classical subject. Other important works for Rockefeller Center were made by Lee Lawrie, including the sculptural façade and the Atlas statue. + +During the Great Depression in the United States, many sculptors were commissioned to make works for the decoration of federal government buildings, with funds provided by the WPA, or Works Progress Administration. They included sculptor Sidney Biehler Waugh, who created stylized and idealized images of workers and their tasks for federal government office buildings. In San Francisco, Ralph Stackpole provided sculpture for the façade of the new San Francisco Stock Exchange building. In Washington D.C., Michael Lantz made works for the Federal Trade Commission building. + +In Britain, Deco public statuary was made by Eric Gill for the BBC Broadcasting House, while Ronald Atkinson decorated the lobby of the former Daily Express Building in London (1932). + +One of the best known and certainly the largest public Art Deco sculpture is the Christ the Redeemer by the French sculptor Paul Landowski, completed between 1922 and 1931, located on a mountain top overlooking Rio de Janeiro, Brazil. + +Studio sculpture + +Many early Art Deco sculptures were small, designed to decorate salons. One genre of this sculpture was called the Chryselephantine statuette, named for a style of ancient Greek temple statues made of gold and ivory. They were sometimes made of bronze, or sometimes with much more lavish materials, such as ivory, onyx, alabaster, and gold leaf. + +One of the best-known Art Deco salon sculptors was the Romanian-born Demétre Chiparus, who produced colourful small sculptures of dancers. Other notable salon sculptors included Ferdinand Preiss, Josef Lorenzl, Alexander Kelety, Dorothea Charol and Gustav Schmidtcassel. Another important American sculptor in the studio format was Harriet Whitney Frishmuth, who had studied with Auguste Rodin in Paris. + +Pierre Le Paguays was a prominent Art Deco studio sculptor, whose work was shown at the 1925 Exposition. He worked with bronze, marble, ivory, onyx, gold, alabaster and other precious materials. + +François Pompon was a pioneer of modern stylised animalier sculpture. He was not fully recognised for his artistic accomplishments until the age of 67 at the Salon d'Automne of 1922 with the work Ours blanc, also known as The White Bear, now in the Musée d'Orsay in Paris. + +Parallel with these Art Deco sculptors, more avant-garde and abstract modernist sculptors were at work in Paris and New York City. The most prominent were Constantin Brâncuși, Joseph Csaky, Alexander Archipenko, Henri Laurens, Jacques Lipchitz, Gustave Miklos, Jean Lambert-Rucki, Jan et Joël Martel, Chana Orloff and Pablo Gargallo. + +Graphic arts + +The Art Deco style appeared early in the graphic arts, in the years just before World War I. It appeared in Paris in the posters and the costume designs of Léon Bakst for the Ballets Russes, and in the catalogues of the fashion designers Paul Poiret. The illustrations of Georges Barbier, and Georges Lepape and the images in the fashion magazine La Gazette du bon ton perfectly captured the elegance and sensuality of the style. In the 1920s, the look changed; the fashions stressed were more casual, sportive and daring, with the woman models usually smoking cigarettes. American fashion magazines such as Vogue, Vanity Fair and Harper's Bazaar quickly picked up the new style and popularized it in the United States. It also influenced the work of American book illustrators such as Rockwell Kent. In Germany, the most famous poster artist of the period was Ludwig Hohlwein, who created colourful and dramatic posters for music festivals, beers, and, late in his career, for the Nazi Party. + +During the Art Nouveau period, posters usually advertised theatrical products or cabarets. In the 1920s, travel posters, made for steamship lines and airlines, became extremely popular. The style changed notably in the 1920s, to focus attention on the product being advertised. The images became simpler, precise, more linear, more dynamic, and were often placed against a single-color background. In France, popular Art Deco designers included Charles Loupot and Paul Colin, who became famous for his posters of American singer and dancer Josephine Baker. Jean Carlu designed posters for Charlie Chaplin movies, soaps, and theatres; in the late 1930s he emigrated to the United States, where, during the World War, he designed posters to encourage war production. The designer Charles Gesmar became famous making posters for the singer Mistinguett and for Air France. Among the best-known French Art Deco poster designers was Cassandre, who made the celebrated poster of the ocean liner SS Normandie in 1935. + +In the 1930s a new genre of posters appeared in the United States during the Great Depression. The Federal Art Project hired American artists to create posters to promote tourism and cultural events. + +Architecture + +The architectural style of art deco made its debut in Paris in 1903–04, with the construction of two apartment buildings in Paris, one by Auguste Perret on rue Benjamin Franklin and the other on rue Trétaigne by Henri Sauvage. The two young architects used reinforced concrete for the first time in Paris residential buildings; the new buildings had clean lines, rectangular forms, and no decoration on the façades; they marked a clean break with the art nouveau style. Between 1910 and 1913, Perret used his experience in concrete apartment buildings to construct the Théâtre des Champs-Élysées, 15 avenue Montaigne. Between 1925 and 1928 Sauvage constructed the new art deco façade of La Samaritaine department store in Paris. + +The Art Deco style was not limited to buildings on land; the ocean liner SS Normandie, whose first voyage was in 1935, featured Art Deco design, including a dining room whose ceiling and decoration were made of glass by Lalique. + +Skyscrapers + +American skyscrapers marked the summit of the Art Deco style; they became the tallest and most recognizable modern buildings in the world. They were designed to show the prestige of their builders through their height, their shape, their color, and their dramatic illumination at night. The American Radiator Building by Raymond Hood (1924) combined Gothic and Deco modern elements in the design of the building. Black brick on the frontage of the building (symbolizing coal) was selected to give an idea of solidity and to give the building a solid mass. Other parts of the façade were covered in gold bricks (symbolizing fire), and the entry was decorated with marble and black mirrors. Another early Art Deco skyscraper was Detroit's Guardian Building, which opened in 1929. Designed by modernist Wirt C. Rowland, the building was the first to employ stainless steel as a decorative element, and the extensive use of colored designs in place of traditional ornaments. + +New York City's skyline was radically changed by the Chrysler Building in Manhattan (completed in 1930), designed by William Van Alen. It was a giant seventy-seven-floor tall advertisement for Chrysler automobiles. The top was crowned by a stainless steel spire, and was ornamented by deco "gargoyles" in the form of stainless steel radiator cap decorations. The base of the tower, thirty-three stories above the street, was decorated with colorful art deco friezes, and the lobby was decorated with art deco symbols and images expressing modernity. + +The Chrysler Building was soon surpassed in height by the Empire State Building by William F. Lamb (1931), in a slightly less lavish Deco style and the RCA Building (now 30 Rockefeller Plaza) by Raymond Hood (1933) which together completely changed New York City's skyline. The tops of the buildings were decorated with Art Deco crowns and spires covered with stainless steel, and, in the case of the Chrysler building, with Art Deco gargoyles modeled after radiator ornaments, while the entrances and lobbies were lavishly decorated with Art Deco sculpture, ceramics, and design. Similar buildings, though not quite as tall, soon appeared in Chicago and other large American cities. Rockefeller Center added a new design element: several tall buildings grouped around an open plaza, with a fountain in the middle. + +"Cathedrals of Commerce" + +The grand showcases of American Art Deco interior design were the lobbies of government buildings, theaters, and particularly office buildings. Interiors were extremely colorful and dynamic, combining sculpture, murals, and ornate geometric design in marble, glass, ceramics and stainless steel. An early example was the Fisher Building in Detroit, by Joseph Nathaniel French; the lobby was highly decorated with sculpture and ceramics. The Guardian Building (originally the Union Trust Building) in Detroit, by Wirt Rowland (1929), decorated with red and black marble and brightly colored ceramics, highlighted by highly polished steel elevator doors and counters. The sculptural decoration installed in the walls illustrated the virtues of industry and saving; the building was immediately termed the "Cathedral of Commerce". The Medical and Dental Building called 450 Sutter Street in San Francisco by Timothy Pflueger was inspired by Mayan architecture, in a highly stylized form; it used pyramid shapes, and the interior walls were covered with highly stylized rows of hieroglyphs. + +In France, the best example of an Art Deco interior during this period was the Palais de la Porte Dorée (1931) by Albert Laprade, Léon Jaussely and Léon Bazin. The building (now the National Museum of Immigration, with an aquarium in the basement) was built for the Paris Colonial Exposition of 1931, to celebrate the people and products of French colonies. The exterior façade was entirely covered with sculpture, and the lobby created an Art Deco harmony with a wood parquet floor in a geometric pattern, a mural depicting the people of French colonies; and a harmonious composition of vertical doors and horizontal balconies. + +Movie palaces + +Many of the best surviving examples of Art Deco are cinemas built in the 1920s and 1930s. The Art Deco period coincided with the conversion of silent films to sound, and movie companies built large display destinations in major cities to capture the huge audience that came to see movies. Movie palaces in the 1920s often combined exotic themes with art deco style; Grauman's Egyptian Theatre in Hollywood (1922) was inspired by ancient Egyptian tombs and pyramids, while the Fox Theater in Bakersfield, California attached a tower in California Mission style to an Art Deco Hall. The largest of all is Radio City Music Hall in New York City, which opened in 1932. Originally designed as theatrical performance space, it quickly transformed into a cinema, which could seat 6,015 customers. The interior design by Donald Deskey used glass, aluminum, chrome, and leather to create a visual escape from reality. The Paramount Theatre in Oakland, California, by Timothy Pflueger, had a colorful ceramic façade, a lobby four stories high, and separate Art Deco smoking rooms for gentlemen and ladies. Similar grand palaces appeared in Europe. The Grand Rex in Paris (1932), with its imposing tower, was the largest cinema in Europe after the 6,000 seats of the Gaumont-Palace (1931-1973). The Gaumont State Cinema in London (1937) had a tower modelled on the Empire State building, covered with cream ceramic tiles and an interior in an Art Deco-Italian Renaissance style. The Paramount Theatre in Shanghai, China (1933) was originally built as a dance hall called The gate of 100 pleasures; it was converted to a cinema after the Communist Revolution in 1949, and now is a ballroom and disco. In the 1930s Italian architects built a small movie palace, the Cinema Impero, in Asmara in what is now Eritrea. Today, many of the movie theatres have been subdivided into multiplexes, but others have been restored and are used as cultural centres in their communities. + +Streamline Moderne + +In the late 1930s, a new variety of Art Deco architecture became common; it was called Streamline Moderne or simply Streamline, or, in France, the Style Paquebot, or Ocean Liner style. Buildings in the style had rounded corners and long horizontal lines; they were built of reinforced concrete and were almost always white; and they sometimes had nautical features, such as railings and portholes that resembled those on a ship. The rounded corner was not entirely new; it had appeared in Berlin in 1923 in the Mossehaus by Erich Mendelsohn, and later in the Hoover Building, an industrial complex in the London suburb of Perivale. In the United States, it became most closely associated with transport; Streamline moderne was rare in office buildings but was often used for bus stations and airport terminals, such as the terminal at La Guardia airport in New York City that handled the first transatlantic flights, via the PanAm Clipper flying boats; and in roadside architecture, such as gas stations and diners. In the late 1930s a series of diners, modelled upon streamlined railroad cars, were produced and installed in towns in New England; at least two examples still remain and are now registered historic buildings. + +Decoration and motifs + +Decoration in the Art Deco period went through several distinct phases. Between 1910 and 1920, as Art Nouveau was exhausted, design styles saw a return to tradition, particularly in the work of Paul Iribe. In 1912 André Vera published an essay in the magazine L'Art Décoratif calling for a return to the craftsmanship and materials of earlier centuries and using a new repertoire of forms taken from nature, particularly baskets and garlands of fruit and flowers. A second tendency of Art Deco, also from 1910 to 1920, was inspired by the bright colours of the artistic movement known as the Fauves and by the colourful costumes and sets of the Ballets Russes. This style was often expressed with exotic materials such as sharkskin, mother of pearl, ivory, tinted leather, lacquered and painted wood, and decorative inlays on furniture that emphasized its geometry. This period of the style reached its high point in the 1925 Paris Exposition of Decorative Arts. In the late 1920s and the 1930s, the decorative style changed, inspired by new materials and technologies. It became sleeker and less ornamental. Furniture, like architecture, began to have rounded edges and to take on a polished, streamlined look, taken from the streamline modern style. New materials, such as nickel or chrome-plated steel, aluminium and bakelite, an early form of plastic, began to appear in furniture and decoration. + +Throughout the Art Deco period, and particularly in the 1930s, the motifs of the décor expressed the function of the building. Theatres were decorated with sculpture which illustrated music, dance, and excitement; power companies showed sunrises, the Chrysler building showed stylized hood ornaments; The friezes of Palais de la Porte Dorée at the 1931 Paris Colonial Exposition showed the faces of the different nationalities of French colonies. The Streamline style made it appear that the building itself was in motion. The WPA murals of the 1930s featured ordinary people; factory workers, postal workers, families and farmers, in place of classical heroes. + +Furniture + +French furniture from 1910 until the early 1920s was largely an updating of French traditional furniture styles, and the art nouveau designs of Louis Majorelle, Charles Plumet and other manufacturers. French furniture manufacturers felt threatened by the growing popularity of German manufacturers and styles, particularly the Biedermeier style, which was simple and clean-lined. The French designer Frantz Jourdain, the President of the Paris Salon d'Automne, invited designers from Munich to participate in the 1910 Salon. French designers saw the new German style and decided to meet the German challenge. The French designers decided to present new French styles in the Salon of 1912. The rules of the Salon indicated that only modern styles would be permitted. All of the major French furniture designers took part in Salon: Paul Follot, Paul Iribe, Maurice Dufrêne, André Groult, André Mare and Louis Suë took part, presenting new works that updated the traditional French styles of Louis XVI and Louis Philippe with more angular corners inspired by Cubism and brighter colours inspired by Fauvism and the Nabis. + +The painter André Mare and furniture designer Louis Süe both participated the 1912 Salon. After the war the two men joined to form their own company, formally called the Compagnie des Arts Française, but usually known simply as Suë and Mare. Unlike the prominent art nouveau designers like Louis Majorelle, who personally designed every piece, they assembled a team of skilled craftsmen and produced complete interior designs, including furniture, glassware, carpets, ceramics, wallpaper and lighting. Their work featured bright colors and furniture and fine woods, such as ebony encrusted with mother of pearl, abalone and silvered metal to create bouquets of flowers. They designed everything from the interiors of ocean liners to perfume bottles for the label of Jean Patou.The firm prospered in the early 1920s, but the two men were better craftsmen than businessmen. The firm was sold in 1928, and both men left. + +The most prominent furniture designer at the 1925 Decorative Arts Exposition was Émile-Jacques Ruhlmann, from Alsace. He first exhibited his works at the 1913 Autumn Salon, then had his own pavilion, the "House of the Rich Collector", at the 1925 Exposition. He used only most rare and expensive materials, including ebony, mahogany, rosewood, ambon and other exotic woods, decorated with inlays of ivory, tortoise shell, mother of pearl, Little pompoms of silk decorated the handles of drawers of the cabinets. His furniture was based upon 18th-century models, but simplified and reshaped. In all of his work, the interior structure of the furniture was completely concealed. The framework usually of oak, was completely covered with an overlay of thin strips of wood, then covered by a second layer of strips of rare and expensive woods. This was then covered with a veneer and polished, so that the piece looked as if it had been cut out of a single block of wood. Contrast to the dark wood was provided by inlays of ivory, and ivory key plates and handles. According to Ruhlmann, armchairs had to be designed differently according to the functions of the rooms where they appeared; living room armchairs were designed to be welcoming, office chairs comfortable, and salon chairs voluptuous. Only a small number of pieces of each design of furniture was made, and the average price of one of his beds or cabinets was greater than the price of an average house. + +Jules Leleu was a traditional furniture designer who moved smoothly into Art Deco in the 1920s; he designed the furniture for the dining room of the Élysée Palace, and for the first-class cabins of the steamship Normandie. his style was characterized by the use of ebony, Macassar wood, walnut, with decoration of plaques of ivory and mother of pearl. He introduced the style of lacquered art deco furniture in the late 1920s, and in the late 1930s introduced furniture made of metal with panels of smoked glass. In Italy, the designer Gio Ponti was famous for his streamlined designs. + +The costly and exotic furniture of Ruhlmann and other traditionalists infuriated modernists, including the architect Le Corbusier, causing him to write a famous series of articles denouncing the arts décoratif style. He attacked furniture made only for the rich and called upon designers to create furniture made with inexpensive materials and modern style, which ordinary people could afford. He designed his own chairs, created to be inexpensive and mass-produced. + +In the 1930s, furniture designs adapted to the form, with smoother surfaces and curved forms. The masters of the late style included Donald Deskey, who was one of the most influential designers; he created the interior of the Radio City Music Hall. He used a mixture of traditional and very modern materials, including aluminium, chrome, and bakelite, an early form of plastic. Other top designers of Art Deco furniture of the 1930s in the United States included Gilbert Rohde, Warren McArthur, and Kem Weber. + +The Waterfall style was popular in the 1930s and 1940s, the most prevalent Art Deco form of furniture at the time. Pieces were typically of plywood finished with blond veneer and with rounded edges, resembling a waterfall. + +Design + +Streamline was a variety of Art Deco which emerged during the mid-1930s. It was influenced by modern aerodynamic principles developed for aviation and ballistics to reduce aerodynamic drag at high velocities. The bullet shapes were applied by designers to cars, trains, ships, and even objects not intended to move, such as refrigerators, gas pumps, and buildings. One of the first production vehicles in this style was the Chrysler Airflow of 1933. It was unsuccessful commercially, but the beauty and functionality of its design set a precedent; meant modernity. It continued to be used in car design well after World War II. + +New industrial materials began to influence the design of cars and household objects. These included aluminium, chrome, and bakelite, an early form of plastic. Bakelite could be easily moulded into different forms, and soon was used in telephones, radios and other appliances. + +Ocean liners also adopted a style of Art Deco, known in French as the Style Paquebot, or "Ocean Liner Style". The most famous example was the SS Normandie, which made its first transatlantic trip in 1935. It was designed particularly to bring wealthy Americans to Paris to shop. The cabins and salons featured the latest Art Deco furnishings and decoration. The Grand Salon of the ship, which was the restaurant for first-class passengers, was bigger than the Hall of Mirrors of the Palace of Versailles. It was illuminated by electric lights within twelve pillars of Lalique crystal; thirty-six matching pillars lined the walls. This was one of the earliest examples of illumination being directly integrated into architecture. The style of ships was soon adapted to buildings. A notable example is found on the San Francisco waterfront, where the Maritime Museum building, built as a public bath in 1937, resembles a ferryboat, with ship railings and rounded corners. The Star Ferry Terminal in Hong Kong also used a variation of the style. + +Textiles + +Textiles were an important part of the Art Deco style, in the form of colourful wallpaper, upholstery and carpets, In the 1920s, designers were inspired by the stage sets of the Ballets Russes, fabric designs and costumes from Léon Bakst and creations by the Wiener Werkstätte. The early interior designs of André Mare featured brightly coloured and highly stylized garlands of roses and flowers, which decorated the walls, floors, and furniture. Stylized Floral motifs also dominated the work of Raoul Dufy and Paul Poiret, and in the furniture designs of J.E. Ruhlmann. The floral carpet was reinvented in Deco style by Paul Poiret. + +The use of the style was greatly enhanced by the introduction of the pochoir stencil-based printing system, which allowed designers to achieve crispness of lines and very vivid colours. Art Deco forms appeared in the clothing of Paul Poiret, Charles Worth and Jean Patou. After World War I, exports of clothing and fabrics became one of the most important currency earners of France. + +Late Art Deco wallpaper and textiles sometimes featured stylized industrial scenes, cityscapes, locomotives and other modern themes, as well as stylized female figures, metallic finishes and geometric designs. + +Fashion + +The new woman of pre-WW1 days became the Amazon of the Art Deco era. Fashion changed dramatically during this period, thanks in particular to designers Paul Poiret and later Coco Chanel. Poiret introduced an important innovation to fashion design, the concept of draping, a departure from the tailoring and patternmaking of the past. He designed clothing cut along straight lines and constructed of rectangular motifs. His styles offered structural simplicity The corseted look and formal styles of the previous period were abandoned, and fashion became more practical, and streamlined. with the use of new materials, brighter colours and printed designs. The designer Coco Chanel continued the transition, popularising the style of sporty, casual chic. + +A particular typology of the era was the Flapper, a woman who cut her hair into a short bob, drank cocktails, smoked in public, and danced late into the night at fashionable clubs, cabarets or bohemian dives. Of course, most women didn't live like this, the Flapper being more a character present in popular imagination than a reality. Another female Art Deco style was the androgynous garçonne of the 1920s, with flattened bosom, dispelled waist and revealed legs, reducing the silhouette to a short tube, topped with a head-hugging cloche hat. + +Jewelry + +In the 1920s and 1930s, designers including René Lalique and Cartier tried to reduce the traditional dominance of diamonds by introducing more colourful gemstones, such as small emeralds, rubies and sapphires. They also placed greater emphasis on very elaborate and elegant settings, featuring less-expensive materials such as enamel, glass, horn and ivory. Diamonds themselves were cut in less traditional forms; the 1925 Exposition saw many diamonds cut in the form of tiny rods or matchsticks. Other popular Art Deco cuts include: + + emerald cut, with long step-cut facets; + asscher cut, more square-shaped than emerald with a high crown and the first diamond cut to ever be patented; + marquise cut, to give the illusion of being bigger and bolder; + baguette cut: small, rectangular step-cut shapes often used to outline bolder stones. + +The settings for diamonds also changed; More and more often jewellers used platinum instead of gold, since it was strong and flexible, and could set clusters of stones. Jewellers also began to use more dark materials, such as enamels and black onyx, which provided a higher contrast with diamonds. + +Jewellery became much more colourful and varied in style. Cartier and the firm of Boucheron combined diamonds with colourful other gemstones cut into the form of leaves, fruit or flowers, to make brooches, rings, earrings, clips and pendants. Far Eastern themes also became popular; plaques of jade and coral were combined with platinum and diamonds, and vanity cases, cigarette cases and powder boxes were decorated with Japanese and Chinese landscapes made with mother of pearl, enamel and lacquer. + +Rapidly changing fashions in clothing brought new styles of jewellery. Sleeveless dresses of the 1920s meant that arms needed decoration, and designers quickly created bracelets of gold, silver and platinum encrusted with lapis-lazuli, onyx, coral, and other colourful stones; Other bracelets were intended for the upper arms, and several bracelets were often worn at the same time. The short haircuts of women in the twenties called for elaborate deco earring designs. As women began to smoke in public, designers created very ornate cigarette cases and ivory cigarette holders. The invention of the wristwatch before World War I inspired jewelers to create extraordinary, decorated watches, encrusted with diamonds and plated with enamel, gold and silver. Pendant watches, hanging from a ribbon, also became fashionable. + +The established jewellery houses of Paris in the period, Cartier, Chaumet, Georges Fouquet, Mauboussin, and Van Cleef & Arpels all created jewellery and objects in the new fashion. The firm of Chaumet made highly geometric cigarette boxes, cigarette lighters, pillboxes and notebooks, made of hard stones decorated with jade, lapis lazuli, diamonds and sapphires. They were joined by many young new designers, each with his own idea of deco. Raymond Templier designed pieces with highly intricate geometric patterns, including silver earrings that looked like skyscrapers. Gerard Sandoz was only 18 when he started to design jewelry in 1921; he designed many celebrated pieces based on the smooth and polished look of modern machinery. The glass designer René Lalique also entered the field, creating pendants of fruit, flowers, frogs, fairies or mermaids made of sculpted glass in bright colors, hanging on cords of silk with tassels. The jeweller Paul Brandt contrasted rectangular and triangular patterns, and embedded pearls in lines on onyx plaques. Jean Despres made necklaces of contrasting colours by bringing together silver and black lacquer, or gold with lapis lazuli. Many of his designs looked like highly polished pieces of machines. Jean Dunand was also inspired by modern machinery, combined with bright reds and blacks contrasting with polished metal. + +Glass art + +Like the Art Nouveau period before it, Art Deco was an exceptional period for fine glass and other decorative objects, designed to fit their architectural surroundings. The most famous producer of glass objects was René Lalique, whose works, from vases to hood ornaments for automobiles, became symbols of the period. He had made ventures into glass before World War I, designing bottles for the perfumes of François Coty, but he did not begin serious production of art glass until after World War I. In 1918, at the age of 58, he bought a large glass works in Combs-la-Ville and began to manufacture both artistic and practical glass objects. He treated glass as a form of sculpture, and created statuettes, vases, bowls, lamps and ornaments. He used demi-crystal rather than lead crystal, which was softer and easier to form, though not as lustrous. He sometimes used coloured glass, but more often used opalescent glass, where part or the whole of the outer surface was stained with a wash. Lalique provided the decorative glass panels, lights and illuminated glass ceilings for the ocean liners in 1927 and the SS Normandie in 1935, and for some of the first-class sleeping cars of the French railroads. At the 1925 Exposition of Decorative Arts, he had his own pavilion, designed a dining room with a table setting and matching glass ceiling for the Sèvres Pavilion, and designed a glass fountain for the courtyard of the Cours des Métiers, a slender glass column which spouted water from the sides and was illuminated at night. + +Other notable Art Deco glass manufacturers included Marius-Ernest Sabino, who specialized in figurines, vases, bowls, and glass sculptures of fish, nudes, and animals. For these he often used an opalescent glass which could change from white to blue to amber, depending upon the light. His vases and bowls featured molded friezes of animals, nudes or busts of women with fruit or flowers. His work was less subtle but more colourful than that of Lalique. + +Other notable Deco glass designers included Edmond Etling, who also used bright opalescent colours, often with geometric patterns and sculpted nudes; Albert Simonet, and Aristide Colotte and Maurice Marinot, who was known for his deeply etched sculptural bottles and vases. The firm of Daum from the city of Nancy, which had been famous for its Art Nouveau glass, produced a line of Deco vases and glass sculpture, solid, geometric and chunky in form. More delicate multi-coloured works were made by Gabriel Argy-Rousseau, who produced delicately shaded vases with sculpted butterflies and nymphs, and Francois Decorchemont, whose vases were streaked and marbled. + +The Great Depression ruined a large part of the decorative glass industry, which depended upon wealthy clients. Some artists turned to designing stained glass windows for churches. In 1937, the Steuben glass company began the practice of commissioning famous artists to produce glassware. Louis Majorelle, famous for his Art Nouveau furniture, designed a remarkable Art Deco stained glass window portraying steel workers for the offices of the Aciéries de Longwy, a steel mill in Longwy, France. + +Amiens Cathedral has a rare example of Art Deco stained glass windows in the Chapel of the Sacred Heart, made in 1932-34 by the Paris glass artist Jean Gaudin based on drawings by Jacques Le Breton. + +Metal art + +Art Deco artists produced a wide variety of practical objects in the Art Deco style, made of industrial materials from traditional wrought iron to chrome-plated steel. The American artist Norman Bel Geddes designed a cocktail set resembling a skyscraper made of chrome-plated steel. Raymond Subes designed an elegant metal grille for the entrance of the Palais de la Porte Dorée, the centre-piece of the 1931 Paris Colonial Exposition. The French sculptor Jean Dunand produced magnificent doors on the theme "The Hunt", covered with gold leaf and paint on plaster (1935). + +Animation +Art Deco visuals and imagery was used in multiple animated films including Batman, Night Hood, All's Fair at the Fair, Merry Mannequins, Page Miss Glory, Fantasia and Sleeping Beauty. The architecture is featured in the fictitious underwater city of Rapture in the Bioshock video game series. + +Art Deco architecture around the world +Art Deco architecture began in Europe, but by 1939 there were examples in large cities on every continent and in almost every country. This is a selection of prominent buildings on each continent. + +For a comprehensive list of existing buildings by country, see: List of Art Deco architecture. + +Africa + +Most Art Deco buildings in Africa were built during European colonial rule, and often designed by Italian, French and Portuguese architects. + +Asia + +Many Art Deco buildings in Asia were designed by European architects. But in the Philippines, local architects such as Juan Nakpil, Juan Arellano, Pablo Antonio and others were preeminent. Many Art Deco landmarks in Asia were demolished during the great economic expansion of Asia the late 20th century, but some notable enclaves of the architecture still remain, particularly in Shanghai and Mumbai. + +Australia and New Zealand + +Melbourne and Sydney, Australia, have several notable Art Deco buildings, including the Manchester Unity Building and the former Russell Street Police Headquarters in Melbourne, the Castlemaine Art Museum in Castlemaine, central Victoria and the Grace Building, AWA Tower and Anzac Memorial in Sydney. + +Several towns in New Zealand, including Napier and Hastings were rebuilt in Art Deco style after the 1931 Hawke's Bay earthquake, and many of the buildings have been protected and restored. Napier has been nominated for UNESCO World Heritage Site status, the first cultural site in New Zealand to be nominated. Wellington has retained a sizeable number of Art Deco buildings. + +North America + +In Canada, surviving Art Deco structures are mainly in the major cities; Montreal, Toronto, Hamilton, Ontario, and Vancouver. They range from public buildings like Vancouver City Hall to commercial buildings (College Park) to public works (R. C. Harris Water Treatment Plant). + +In Mexico, the most imposing Art Deco example is interior of the Palacio de Bellas Artes (Palace of Fine Arts), finished in 1934 with its elaborate décor and murals. Examples of Art Deco residential architecture can be found in the Condesa district, many designed by Francisco J. Serrano. + +In the United States, Art Deco buildings are found from coast to coast, in all the major cities. It was most widely used for office buildings, train stations, airport terminals, and cinemas; residential buildings are rare. During the 1920s and 1930s architects in the Southwestern United States, particularly in the US state of New Mexico, combined Pueblo Revival with Territorial Style and Art Deco to create Pueblo Deco, as seen in the KiMo Theater in Albuquerque. In the 1930s, the more austere streamline style became popular. Many buildings were demolished between 1945 and the late 1960s, but then efforts began to protect the best examples. The City of Miami Beach established the Miami Beach Architectural District to preserve the fine collection of Art Deco buildings found there. + +Central America and the Caribbean + +Art Deco buildings can be found throughout Central America, including in Cuba. + +Europe + +The architectural style first appeared in Paris with the Théâtre des Champs-Élysées (1910–13) by Auguste Perret but then spread rapidly around Europe, until examples could be found in nearly every large city, from London to Moscow. In Germany two variations of Art Deco flourished in the 1920s and 30s: The Neue Sachlichkeit style and Expressionist architecture. Notable examples include Erich Mendelsohn's Mossehaus and Schaubühne in Berlin, Fritz Höger's Chilehaus in Hamburg and his Kirche am Hohenzollernplatz in Berlin, the in Hanover and the in Berlin. + +One of the largest Art Deco buildings in Western Europe is the National Basilica of the Sacred Heart in Koekelberg, Brussels. In 1925, architect Albert van Huffel won the Grand Prize for Architecture with his scale model of the basilica at the Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris. + +Spain and Portugal have some striking examples of Art Deco buildings, particularly movie theaters. Examples in Portugal are the Capitólio Theater (1931) and the Éden Cine-Theatre (1937) in Lisbon, the Rivoli Theater (1937) and the Coliseu (1941) in Porto and the Rosa Damasceno Theater (1937) in Santarém. An example in Spain is the Cine Rialto in Valencia (1939). + +During the 1930s, Art Deco had a noticeable effect on house design in the United Kingdom, as well as the design of various public buildings. Straight, white-rendered house frontages rising to flat roofs, sharply geometric door surrounds and tall windows, as well as convex-curved metal corner windows, were all characteristic of that period. + +The London Underground is famous for many examples of Art Deco architecture, and there are a number of buildings in the style situated along the Golden Mile in Brentford. Also in West London is the Hoover Building, which was originally built for The Hoover Company and was converted into a superstore in the early 1990s. + +Bucharest, Romania +Bucharest, once known as the "Little Paris" of the 19th century, engaged in a new design after World War I, redirected its inspiration towards New York City. The 1930s brought a new fashion which echoed in the cinema, theatre, dancing styles, art and architecture. Bucharest during the 1930s was marked by more and more art deco architecture from the bigger boulevards like Bulevardul Magheru to the private houses and smaller districts. The Telephone Palace, an early landmark of modern Bucharest, was the first skyscraper of the city. It was the tallest building between 1933 and the 1950s, with a height of . The architects were Louis Weeks and Edmond van Saanen Algi and engineer Walter Troy. The art deco monuments are a crucial part of the character of Bucharest since they describe and mark an important period from its history, the interbellic life (World War I–World War II). Most of the buildings from those years are prone to catastrophe, as Bucharest is located in an earthquake zone. + +India + +The Indian Institute of Architects, founded in Mumbai in 1929, played a prominent role in propagating the Art Deco movement. In November 1937, this institute organised the 'Ideal Home Exhibition' held in the Town Hall in Mumbai which spanned over 12 days and attracted about one hundred thousand visitors. As a result, it was declared a success by the 'Journal of the Indian Institute of Architects'. The exhibits displayed the 'ideal', or better described as the most 'modern' arrangements for various parts of the house, paying close detail to avoid architectural blunders and present the most efficient and well-thought-out models. The exhibition focused on various elements of a home ranging from furniture, elements of interior decoration as well as radios and refrigerators using new and scientifically relevant materials and methods. +Guided by their desire to emulate the west, the Indian architects were fascinated by the industrial modernity that Art Deco offered. The western elites were the first to experiment with the technologically advanced facets of Art Deco, and architects began the process of transformation by the early 1930s. + +Mumbai's expanding port commerce in the 1930s resulted in the growth of educated middle class population. It also saw an increase of people migrating to Mumbai in search of job opportunities. This led to the pressing need for new developments through Land Reclamation Schemes and construction of new public and residential buildings. Parallelly, the changing political climate in the country and the aspirational quality of the Art Deco aesthetics led to a whole-hearted acceptance of the building style in the city's development. Most of the buildings from this period can be seen spread throughout the city neighbourhoods in areas such as Churchgate, Colaba, Fort, Mohammed Ali Road, Cumbala Hill, Dadar, Matunga, Bandra and Chembur. + +South America + +Art Deco in South America is especially present in countries which received a great wave of immigration in the first half of the 20th century, with notable works in their richest cities, like São Paulo and Rio de Janeiro in Brazil and Buenos Aires in Argentina. The Kavanagh Building in Buenos Aires (1934), by Sánchez, Lagos and de la Torre, was the tallest reinforced-concrete structure when it was completed and is a notable example of late Art Deco style. + +Preservation and Neo Art Deco + +In many cities, efforts have been made to protect the remaining Art Deco buildings. In many U.S. cities, historic art deco cinemas have been preserved and turned into cultural centres. Even more modest art deco buildings have been preserved as part of America's architectural heritage; an art deco café and gas station along Route 66 in Shamrock, Texas is an historic monument. The Miami Beach Architectural District protects several hundred old buildings, and requires that new buildings comply with the style. In Havana, Cuba, many Art Deco buildings have badly deteriorated. Efforts are underway to bring the buildings back to their original appearance. + +In the 21st century, modern variants of Art Deco, called Neo Art Deco (or Neo-Art Deco), have appeared in some American cities, inspired by the classic Art Deco buildings of the 1920s and 1930s. Examples include the NBC Tower in Chicago, inspired by 30 Rockefeller Plaza in New York City; and Smith Center for the Performing Arts in Las Vegas, Nevada, which includes art deco features from Hoover Dam, 80 km (50 miles) away. + +Gallery + +See also + + Art Deco in Paris + Roaring Twenties + 1920s in Western fashion + Années folles + 1933 Chicago World's Fair Century of Progress + 1936 Fair Park built for Texas Centennial Exposition + Art Deco stamps + Pueblo Deco architecture + Art Nouveau + +References + +Bibliography + +External links + + Art Deco Miami Beach + Art Deco Mumbai + Art Deco Montreal + Art Deco Society of Washington + living room interior design + Art Deco Society of California + Art Deco Rio de Janeiro + Art Deco Shanghai + Art Deco Museum in Moscow + Art Deco Society New York + Art Deco Society of Los Angeles + Art Deco Walk in Montreal + + +20th century in the arts +20th-century architectural styles +Art movements +Decorative arts +Modern art +ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII). The term is also loosely used to refer to text-based visual art in general. ASCII art can be created with any text editor, and is often used with free-form languages. Most examples of ASCII art require a fixed-width font (non-proportional fonts, as on a traditional typewriter) such as Courier for presentation. + +Among the oldest known examples of ASCII art are the +creations by computer-art pioneer Kenneth Knowlton from around 1966, who was working for Bell Labs at the time. "Studies in Perception I" by Knowlton and Leon Harmon from 1966 shows some examples of their early ASCII art. + +ASCII art was invented, in large part, because early printers often lacked graphics ability and thus, characters were used in place of graphic marks. Also, to mark divisions between different print jobs from different users, bulk printers often used ASCII art to print large banner pages, making the division easier to spot so that the results could be more easily separated by a computer operator or clerk. ASCII art was also used in early e-mail when images could not be embedded. + +History + +Typewriter art + +Since 1867, typewriters have been used for creating visual art. + +TTY and RTTY +TTY stands for "TeleTYpe" or "TeleTYpewriter", and is also known as Teleprinter or Teletype. +RTTY stands for Radioteletype; character sets such as Baudot code, which predated ASCII, were used. According to a chapter in the "RTTY Handbook", text images have been sent via teletypewriter as early as 1923. However, none of the "old" RTTY art has been discovered yet. What is known is that text images appeared frequently on radioteletype in the 1960s and the 1970s. + +Line-printer art +In the 1960s, Andries van Dam published a representation of an electronic circuit produced on an IBM 1403 line printer. At the same time, Kenneth Knowlton was producing realistic images, also on line printers, by overprinting several characters on top of one another. +Note that it was not ASCII art in a sense that the 1403 was driven by an EBCDIC-coded platform and the character sets and trains available on the 1403 were derived from EBCDIC rather than ASCII, despite some glyphs commonalities. + +ASCII art +The widespread usage of ASCII art can be traced to the computer bulletin board systems of the late 1970s and early 1980s. The limitations of computers of that time period necessitated the use of text characters to represent images. Along with ASCII's use in communication, however, it also began to appear in the underground online art groups of the period. An ASCII comic is a form of webcomic which uses ASCII text to create images. In place of images in a regular comic, ASCII art is used, with the text or dialog usually placed underneath. + +During the 1990s, graphical browsing and variable-width fonts became increasingly popular, leading to a decline in ASCII art. Despite this, ASCII art continued to survive through online MUDs, an acronym for "Multi-User Dungeon", (which are textual multiplayer role-playing video games), Internet Relay Chat, Email, message boards, and other forms of online communication which commonly employ the needed fixed-width. + +It is seen to this day on the CLI app Neofetch, which displays the logo of the OS on which it is invoked. + +ANSI +ASCII and more importantly, ANSI were staples of the early technological era; terminal systems relied on coherent presentation using color and control signals standard in the terminal protocols. + +Over the years, warez groups began to enter the ASCII art scene. Warez groups usually release .nfo files with their software, cracks or other general software reverse-engineering releases. The ASCII art will usually include the warez group's name and maybe some ASCII borders on the outsides of the release notes, etc. + +BBS systems were based on ASCII and ANSI art, as were most DOS and similar console applications, and the precursor to AOL. + +Uses + +ASCII art is used wherever text can be more readily printed or transmitted than graphics, or in some cases, where the transmission of pictures is not possible. This includes typewriters, teleprinters, non-graphic computer terminals, printer separators, in early computer networking (e.g., BBSes), email, and Usenet news messages. ASCII art is also used within the source code of computer programs for representation of company or product logos, and flow control or other diagrams. In some cases, the entire source code of a program is a piece of ASCII art – for instance, an entry to one of the earlier International Obfuscated C Code Contest is a program that adds numbers, but visually looks like a binary adder drawn in logic ports. + +Some electronic schematic archives represent the circuits using ASCII art. + +Examples of ASCII-style art predating the modern computer era can be found in the June 1939, July 1948 and October 1948 editions of Popular Mechanics. + +Early computer games played on terminals frequently used ASCII art to simulate graphics, most notably the roguelike genre using ASCII art to visually represent dungeons and monsters within them. "0verkill" is a 2D platform multiplayer shooter game designed entirely in color ASCII art. MPlayer and VLC media player can display videos as ASCII art through the AAlib library. ASCII art is used in the making of DOS-based ZZT games. + +Many game walkthrough guides come as part of a basic .txt file; this file often contains the name of the game in ASCII art. Such as below, word art is created using backslashes and other ASCII values in order to create the illusion of 3D. + +Types and styles +Different techniques could be used in ASCII art to obtain different artistic effects. + +"Typewriter-style" lettering, made from individual letter characters: +Line art, for creating shapes: + .--. /\ + '--' /__\ (^._.^)~ <(o.o )> + +Solid art, for creating filled objects: + .g@8g. db + 'Y8@P' d88b + +Shading, using symbols with various intensities for creating gradients or contrasts: + :$#$: "4b.

They are commonly referred to as 'emoticon', 'smilie', or 'smiley'. There is another type of one-line ASCII art that does not require the mental rotation of pictures, which is widely known in Japan as kaomoji (literally "face characters".) + +More complex examples use several lines of text to draw large symbols or more complex figures. Hundreds of different text smileys have developed over time, but only a few are generally accepted, used and understood. + +ASCII comic +An ASCII comic is a form of webcomic. + +The Adventures of Nerd Boy +The Adventures of Nerd Boy, or just Nerd Boy, was an ASCII comic, published by Joaquim Gândara between 5 August 2001 and 17 July 2007, and consisting of 600 strips. They were posted to ASCII art newsgroup alt.ascii-art and on the website. Some strips have been translated to Polish and French. + +Styles of the computer underground text art scene + +Atari 400/800 ATASCII +The Atari 400/800, which were released in 1979, did not follow the ASCII standard and had their own character set, called ATASCII. The emergence of ATASCII art coincided with the growing popularity of BBS Systems caused by availability of the acoustic couplers that were compatible with the 8-bit home computers. ATASCII text animations are also referred to as "break animations" by the Atari sceners. + +C-64 PETSCII +The Commodore 64, which was released in 1982, also did not follow the ASCII standard. The C-64 character set is called PETSCII, an extended form of ASCII-1963. As with the Atari's ATASCII art, C-64 fans developed a similar scene that used PETSCII for their creations. + +"Block ASCII" / "High ASCII" style ASCII art on the IBM PC + +So-called "block ASCII" or "high ASCII" uses the extended characters of the 8-bit code page 437, which is a proprietary standard introduced by IBM in 1979 (ANSI Standard x3.16) for the IBM PC DOS and MS-DOS operating systems. "Block ASCIIs" were widely used on the PC during the 1990s until the Internet replaced BBSes as the main communication platform. Until then, "block ASCIIs" dominated the PC Text Art Scene. + +The first art scene group that focused on the extended character set of the PC in their art work was called "Aces of ANSI Art" (). Some members left in 1990, and formed a group called "ANSI Creators in Demand" (ACiD). In that same year the second major underground art scene group was founded, ICE, "Insane Creators Enterprise". + +There is some debate between ASCII and block ASCII artists, with "Hardcore" ASCII artists maintaining that block ASCII art is in fact not ASCII art, because it does not use the 128 characters of the original ASCII standard. On the other hand, block ASCII artists argue that if their art uses only characters of the computers character set, then it is to be called ASCII, regardless if the character set is proprietary or not. + +Microsoft Windows does not support the ANSI Standard x3.16. One can view block ASCIIs with a text editor using the font "Terminal", but it will not look exactly as it was intended by the artist. With a special ASCII/ANSI viewer, such as ACiDView for Windows (see ASCII and ANSI art viewers), one can see block ASCII and ANSI files properly. An example that illustrates the difference in appearance is part of this article. Alternatively, one could look at the file using the TYPE command in the command prompt. + +"Amiga"/"Oldskool" style ASCII art + +In the art scene one popular ASCII style that used the 7-bit standard ASCII character set was the so-called "Oldskool" style. It is also called "Amiga style", due to its origin and widespread use on the Commodore Amiga computers. The style uses primarily the characters: _/\-+=.()<>:. The "oldskool" art looks more like the outlined drawings of shapes than real pictures. +This is an example of "Amiga style" (also referred to as "old school" or "oldskool" style) scene ASCII art. + +The Amiga ASCII scene surfaced in 1992, seven years after the introduction of the Commodore Amiga 1000. The Commodore 64 PETSCII scene did not make the transition to the Commodore Amiga as the C64 demo and warez scenes did. Among the first Amiga ASCII art groups were ART, Epsilon Design, Upper Class, Unreal (later known as "DeZign"). This means that the text art scene on the Amiga was actually younger than the text art scene on the PC. The Amiga artists also did not call their ASCII art style "Oldskool". That term was introduced on the PC. When and by whom is unknown and lost in history. + +The Amiga style ASCII artwork was most often released in the form of a single text file, which included all the artwork (usually requested), with some design parts in between, as opposed to the PC art scene where the art work was released as a ZIP archive with separate text files for each piece. Furthermore, the releases were usually called "ASCII collections" and not "art packs" like on the IBM PC. + +In text editors + _ ___ _ _ +| ___|_ _/ ___| | ___| |_ +| |_ | | | _| |/ _ \ __| +| _| | | |_| | | __/ |_ +|_| |___\|_|\___|\__| +This kind of ASCII art is handmade in a text editor. Popular editors used to make this kind of ASCII art include Microsoft Notepad, CygnusEditor aka. CED (Amiga), and EditPlus2 (PC). + +Oldskool font example from the PC, which was taken from the ASCII editor FIGlet. + +Newskool style ASCII art + +"Newskool" is a popular form of ASCII art which capitalizes on character strings like "$#Xxo". In spite of its name, the style is not "new"; on the contrary, it was very old but fell out of favor and was replaced by "Oldskool" and "Block" style ASCII art. It was dubbed "Newskool" upon its comeback and renewed popularity at the end of the 1990s. + +Newskool changed significantly as the result of the introduction of extended proprietary characters. The classic 7-bit standard ASCII characters remain predominant, but the extended characters are often used for "fine tuning" and "tweaking". The style developed further after the introduction and adaptation of Unicode. + +Methods for generating ASCII art + +While some prefer to use a simple text editor to produce ASCII art, specialized programs, such as JavE have been developed that often simulate the features and tools in bitmap image editors. For Block ASCII art and ANSI art the artist almost always uses a special text editor, because to generate the required characters on a standard keyboard, one needs to know the Alt code for each character. For example, + will produce ▓, + will produce ▒, and + will produce ◘. + +The special text editors have sets of special characters assigned to existing keys on the keyboard. Popular DOS-based editors, such as TheDraw and ACiDDraw had multiple sets of different special characters mapped to the function keys to make the use of those characters easier for the artist who can switch between individual sets of characters via basic keyboard shortcuts. PabloDraw is one of the very few special ASCII/ANSI art editors that were developed for Windows. + +Image to text conversion +Other programs allow one to automatically convert an image to text characters, which is a special case of vector quantization. A method is to sample the image down to grayscale with less than 8-bit precision, and then assign a character for each value. Such ASCII art generators often allow users to choose the intensity and contrast of the generated image. + +Three factors limit the fidelity of the conversion, especially of photographs: + + depth (solutions: reduced line spacing; bold style; block elements; colored background; good shading); + sharpness (solutions: a longer text, with a smaller font; a greater set of characters; variable width fonts); + ratio (solutions with compatibility issues: font with a square grid; stylized without extra line spacing). + +Examples of converted images are given below. + +This is one of the earliest forms of ASCII art, dating back to the early days of the 1960s minicomputers and teletypes. During the 1970s, it was popular in US malls to get a t-shirt with a photograph printed in ASCII art on it from an automated kiosk containing a computer, and London's Science Museum had a similar service to produce printed portraits. With the advent of the web, HTML and CSS, many ASCII conversion programs will now quantize to a full RGB colorspace, enabling colorized ASCII images. + +Still images or movies can also be converted to ASCII on various UNIX and UNIX-like systems using the AAlib (black and white) or libcaca (colour) graphics device driver, or the VLC media player or mpv under Windows, Linux or macOS; all of which render the screen using ASCII symbols instead of pixels. + +There are also a number of smartphone applications, such as ASCII cam for Android, that generate ASCII art in real-time using input from the phone's camera. These applications typically allow the ASCII art to be saved as either a text file or as an image made up of ASCII text. + +Non fixed-width ASCII +Most ASCII art is created using a monospaced font, such as Courier, where all characters are identical in width. Early computers in use when ASCII art came into vogue had monospaced fonts for screen and printer displays. Today, most of the more commonly used fonts in word processors, web browsers and other programs are proportional fonts, such as Helvetica or Times Roman, where different widths are used for different characters. ASCII art drawn for a fixed width font will usually appear distorted, or even unrecognizable when displayed in a proportional font. + +Some ASCII artists have produced art for display in proportional fonts. These ASCIIs, rather than using a purely shade-based correspondence, use characters for slopes and borders and use block shading. These ASCIIs generally offer greater precision and attention to detail than fixed-width ASCIIs for a lower character count, although they are not as universally accessible since they are usually relatively font-specific. + +Animated ASCII art +Animated ASCII art started in 1970 from so-called VT100 animations produced on VT100 terminals. These animations were simply text with cursor movement instructions, deleting and erasing the characters necessary to appear animated. Usually, they represented a long hand-crafted process undertaken by a single person to tell a story. + +Contemporary web browser revitalized animated ASCII art again. It became possible to display animated ASCII art via JavaScript or Java applets. Static ASCII art pictures are loaded and displayed one after another, creating the animation, very similar to how movie projectors unreel film reel and project the individual pictures on the big screen at movie theaters. A new term was born: "ASCIImation" – another name of animated ASCII art. A seminal work in this arena is the Star Wars ASCIImation. More complicated routines in JavaScript generate more elaborate ASCIImations showing effects like Morphing effects, star field emulations, fading effects and calculated images, such as mandelbrot fractal animations. + +There are now many tools and programs that can transform raster images into text symbols; some of these tools can operate on streaming video. For example, the music video for American singer Beck's song "Black Tambourine" is made up entirely of ASCII characters that approximate the original footage. VLC, a media player software, can render any video in colored ASCII through the libcaca module. + +Other text-based visual art +There are a variety of other types of art using text symbols from character sets other than ASCII and/or some form of color coding. Despite not being pure ASCII, these are still often referred to as "ASCII art". The character set portion designed specifically for drawing is known as the line drawing characters or pseudo-graphics. + +ANSI art + +The IBM PC graphics hardware in text mode uses 16 bits per character. It supports a variety of configurations, but in its default mode under DOS they are used to give 256 glyphs from one of the IBM PC code pages (Code page 437 by default), 16 foreground colors, eight background colors, and a flash option. Such art can be loaded into screen memory directly. ANSI.SYS, if loaded, also allows such art to be placed on screen by outputting escape sequences that indicate movements of the screen cursor and color/flash changes. If this method is used then the art becomes known as ANSI art. The IBM PC code pages also include characters intended for simple drawing which often made this art appear much cleaner than that made with more traditional character sets. Plain text files are also seen with these characters, though they have become far less common since Windows GUI text editors (using the Windows ANSI code page) have largely replaced DOS-based ones. + +Shift_JIS and Japan + +In Japan, ASCII art (AA) is mainly known as Shift_JIS art. Shift JIS offers a larger selection of characters than plain ASCII (including characters from Japanese scripts and fullwidth forms of ASCII characters), and may be used for text-based art on Japanese websites. + +Often, such artwork is designed to be viewed with the default Japanese font on a platform, such as the proportional MS P Gothic. + +Kaomoji + +Users on ASCII-NET, in which the word ASCII refers to the ASCII Corporation rather than the American Standard Code for Information Interchange, popularised a style of in which the face appears upright rather than rotated. + +Unicode + +Unicode would seem to offer the ultimate flexibility in producing text based art with its huge variety of characters. However, finding a suitable fixed-width font is likely to be difficult if a significant subset of Unicode is desired. (Modern UNIX-style operating systems do provide complete fixed-width Unicode fonts, e.g. for xterm. Windows has the Courier New font, which includes characters like ┌╥─╨┐♥☺Ƹ̵̡Ӝ̵̨̄Ʒ). Also, the common practice of rendering Unicode with a mixture of variable width fonts is likely to make predictable display hard, if more than a tiny subset of Unicode is used. ≽ʌⱷ҅ᴥⱷʌ≼ is an adequate representation of a cat's face in a font with varying character widths. + +Control and combining characters + +The combining characters mechanism of Unicode provides considerable ways of customizing the style, even obfuscating the text (e.g. via an online generator like Obfuscator, which focuses on the filters). Glitcher is one example of Unicode art, initiated in 2012: These symbols, intruding up and down, are made by combining lots of diacritical marks. It’s a kind of art. There’s quite a lot of artists who use the Internet or specific social networks as their canvas. The corresponding creations are favored in web browsers (thanks to their always better support), as geekily stylized usernames for social networks. With a fair compatibility, and among different online tools, [Facebook symbols] showcases various types of Unicode art, mainly for aesthetic purpose (Ɯıḳĭƥḙȡḯả Wîkipêȡıẚ Ẉǐḳîṗȅḍȉā Ẃįḵįṗẻḑìẵ Ẉĭḵɪṕḗdïą Ẇïƙỉpểɗĭà Ẅȉḱïṕȩđĩẵ etc.). Besides, the creations can be hand-crafted (by programming), or pasted from mobile applications (e.g. the category of 'fancy text' tools on Android). The underlying technique dates back to the old systems that incorporated control characters, though. E.g. the German composite ö would be imitated on ZX Spectrum by overwriting " after backspace and o. + +Overprinting (surprint) +In the 1970s and early 1980s it was popular to produce a kind of text art that relied on overprinting. This could be produced either on a screen or on a printer by typing a character, backing up, and then typing another character, just as on a typewriter. This developed into sophisticated graphics in some cases, such as the PLATO system (circa 1973), where superscript and subscript allowed a wide variety of graphic effects. A common use was for emoticons, with WOBTAX and VICTORY both producing convincing smiley faces. Overprinting had previously been used on typewriters, but the low-resolution pixelation of characters on video terminals meant that overprinting here produced seamless pixel graphics, rather than visibly overstruck combinations of letters on paper. + +Beyond pixel graphics, this was also used for printing photographs, as the overall darkness of a particular character space dependent on how many characters, as well as the choice of character, were printed in a particular place. Thanks to the increased granularity of tone, photographs were often converted to this type of printout. Even manual typewriters or daisy wheel printers could be used. The technique has fallen from popularity since all cheap printers can easily print photographs, and a normal text file (or an e-mail message or Usenet posting) cannot represent overprinted text. However, something similar has emerged to replace it: shaded or colored ASCII art, using ANSI video terminal markup or color codes (such as those found in HTML, IRC, and many internet message boards) to add a bit more tone variation. In this way, it is possible to create ASCII art where the characters only differ in color. + +See also + Micrography + Types and styles: Alt code, ASCII stereogram, box-drawing characters, emoticon, FILE ID.DIZ, .nfo (release info file) + Pre-ASCII history: Calligram, Concrete poetry, Typewriter, Typewriter mystery game, Teleprinter, Radioteletype + Related art: ANSI art, ASCII porn, ATASCII, Fax art, PETSCII, Shift JIS art, Text semigraphics + Related context: Bulletin board system (BBS), Computer art scene, :Category:Artscene groups + Software: AAlib, cowsay + Unicode: Homoglyph, Duplicate characters in Unicode + +References + +Further reading + + + + + + (Polish translators: Ania Górecka [ag], Asia Mazur [as], Błażej Kozłowski [bug], Janusz [jp], Łukasz Dąbrowski [luk], Łukasz Tyrała [lt.], Łukasz Wilk [wilu], Marcin Gliński [fsc]) + +External links + + + media4u.ch - ASCII Art (ASCII Art Movie.

English is the most widely spoken language in the United States and in most circumstances is the de facto common language used in government, education and commerce. Since the late 20th century, American English has become the most influential form of English worldwide. + +American English varieties include many patterns of pronunciation, vocabulary, grammar and particularly spelling that are unified nationwide but distinct from other English dialects around the world. Any American or Canadian accent perceived as lacking noticeably local, ethnic or cultural markers is known in linguistics as General American, a fairly uniform accent continuum native to certain regions of the U.S. and associated nationally with broadcast mass media and highly educated speech. However, historical and present linguistic evidence does not support the notion of there being one single mainstream American accent. The sound of American English continues to evolve, with some local accents disappearing, but several larger regional accents having emerged in the 20th century. + +History +The use of English in the United States is a result of British colonization of the Americas. The first wave of English-speaking settlers arrived in North America during the early 17th century, followed by further migrations in the 18th and 19th centuries. During the 17th and 18th centuries, dialects from many different regions of England and the British Isles existed in every American colony, allowing a process of extensive dialect mixture and leveling in which English varieties across the colonies became more homogeneous compared with the varieties in Britain. English thus predominated in the colonies even by the end of the 17th century's first immigration of non-English speakers from Western Europe and Africa. Additionally, firsthand descriptions of a fairly uniform American English (particularly in contrast to the diverse regional dialects of British English) became common after the mid-18th century, while at the same time speakers' identification with this new variety increased. +Since the 18th century, American English has developed into some new varieties, including regional dialects that retain minor influences from waves of immigrant speakers of diverse languages, primarily European languages. + +Some racial and regional variation in American English reflects these groups' geographic settlement, their de jure or de facto segregation, and patterns in their resettlement. This can be seen, for example, in the influence of the Scotch-Irish immigration in Appalachia developing Appalachian English and the Great Migration bringing African-American Vernacular English to the Great Lakes urban centers. + +Phonology + +Any phonologically unmarked North American accent is known as "General American" (akin to Received Pronunciation in British English, which has been referred to as "General British"). This section mostly refers to such General American features. + +Conservative phonology +Studies on historical usage of English in both the United States and the United Kingdom suggest that spoken American English did not simply deviate away from period British English, but is conservative in some ways, preserving certain features contemporary British English has since lost. + +Full rhoticity (or R-fulness) is typical of American accents, pronouncing the phoneme (corresponding to the letter ) in all environments, including after vowels, such as in pearl, car and court. Non-rhotic American accents, those that do not pronounce except before a vowel, such as some Eastern New England, New York, a specific few (often older) Southern, and African American vernacular accents, are often quickly noticed by General American listeners and perceived to sound especially ethnic, regional or "old-fashioned". + +Rhoticity is common in most American accents, although it is now rare in England, because during the 17th-century British colonization nearly all dialects of English were rhotic, and most North American English simply remained that way. The preservation of rhoticity in North America was also supported by continuing waves of rhotic-accented Scotch-Irish immigrants, most intensely during the 18th century (and moderately during the following two centuries) when the Scotch-Irish eventually made up one-seventh of the colonial population. Scotch-Irish settlers spread from Delaware and Pennsylvania throughout the larger Mid-Atlantic region, the inland regions of both the South and North and throughout the West: American dialect areas that were all uninfluenced by upper-class non-rhoticity and that consequently have remained consistently rhotic. The pronunciation of is a postalveolar approximant or retroflex approximant , but a unique "bunched tongue" variant of the approximant r sound is also associated with the United States, perhaps mostly in the Midwest and the South. + +American accents that have not undergone the cot–caught merger (the lexical sets and ) have instead retained a – split: a 17th-century distinction in which certain words (labeled as the lexical set) separated away from the set. The split, which has now reversed in most British English, simultaneously shifts this relatively recent set into a merger with the (caught) set. Having taken place prior to the unrounding of the cot vowel, it results in lengthening and perhaps raising, merging the more recently separated vowel into the vowel in the following environments: before many instances of , , and particularly (as in Austria, cloth, cost, loss, off, often, etc.), a few instances before (as in strong, long, wrong), and variably by region or speaker in gone, on, and certain other words. + +The standard accent of southern England, Received Pronunciation (RP), has evolved in other ways compared to which General American has remained relatively conservative. Examples include the modern RP features of a trap–bath split and the fronting of , neither of which is typical of General American accents. Moreover, American dialects do not participate in H-dropping, an innovative feature that now characterizes perhaps a majority of the regional dialects of England. + +Innovative phonology +However, General American is also innovative in a number of ways: + Unrounded : The American phenomenon of the vowel (often spelled in words like box, don, clock, notch, pot, etc.) being produced without rounded lips, like the vowel, allows father and bother to rhyme, the two vowels now unified as the single phoneme . The father–bother vowel merger is in a transitional or completed stage in nearly all North American English. Exceptions are in northeastern New England English (such as the Boston accent), the Pittsburgh accent, and variably in some older New York accents, which may retain a rounded articulation. +Cot–caught merger in transition: There is no single American way to pronounce the vowels in words like cot (the ah vowel) versus caught (the aw vowel), largely because of a merger occurring between the two sounds in some parts of North America, but not others. American speakers with a completed merger pronounce the two historically separate vowels with the same sound (especially in the West, northern New England, West Virginia, western Pennsylvania, and the Upper Midwest), but other speakers have no trace of a merger at all (especially in the South, the Great Lakes region, southern New England, and the Mid-Atlantic and New York metropolitan areas) and so pronounce each vowel with distinct sounds . Among speakers who distinguish between the two, the vowel of cot (usually transcribed in American English as ), is often a central or advanced back , while is pronounced with more rounded lips and/or phonetically higher in the mouth, close to or , but with only slight rounding. Among speakers who do not distinguish between them, thus producing a cot–caught merger, usually remains a back vowel, , sometimes showing lip rounding as . Therefore, even mainstream Americans vary greatly with this speech feature, with possibilities ranging from a full merger to no merger at all. A transitional stage of the merger is also common in scatterings throughout the United States, most consistently in the American Midlands lying between the historical dialect regions of the North and the South, while younger Americans, in general, tend to be transitioning toward the merger. According to a 2003 dialect survey carried out across the United States, about 61% of participants perceive themselves as keeping the two vowels distinct and 39% do not. A 2009 follow-up survey put the percentages at 58% non-merging speakers and 41% merging. + in special words: The vowel, rather than the one in or (as in Britain), is used in function words and certain other words like was, of, from, what, everybody, nobody, somebody, anybody, and, for many speakers because and rarely even want, when stressed. + Vowel mergers before intervocalic : The mergers of certain vowels before are typical throughout North America, the only exceptions existing primarily along the East Coast: +Mary–marry–merry merger in transition: According to the 2003 dialect survey, nearly 57% of participants from around the country self-identified as merging the sounds (as in the first syllable of parish), (as in the first syllable of perish), and (as in pear or pair). The merger is already complete everywhere except along some areas of the Atlantic Coast. +Hurry–furry merger: The pre- vowels in words like hurry and furry are merged in most American accents to or a syllabic consonant . Roughly only 10% of American English speakers acknowledge the distinct hurry vowel before , according to the same dialect survey aforementioned. +Mirror–nearer merger in transition: The pre- vowels in words like mirror and nearer are merged or very similar in most American accents. The quality of the historic mirror vowel in the word miracle is quite variable. +Americans vary slightly in their pronunciations of R-colored vowels such as those in and , which sometimes monophthongizes towards and or tensing towards and respectively. That causes pronunciations like for pair/pear and for peer/pier. Also, is often reduced to , so that cure, pure, and mature may all end with the sound , thus rhyming with blur and sir. The word sure is also part of the rhyming set as it is commonly pronounced . + Yod-dropping: Dropping of after a consonant is much more extensive than in most of England. In most North American accents, is "dropped" or "deleted" after all alveolar and interdental consonants (that is: everywhere except after /p/, /b/, /f/, /h/, /k/, and /m/) and so new, duke, Tuesday, assume are pronounced , , , (compare with Standard British , , , ). + + T-glottalization: is normally pronounced as a glottal stop when both after a vowel or a liquid and before a syllabic or any non-syllabic consonant, as in button or fruitcake . In absolute final position after a vowel or liquid, is also replaced by, or simultaneously articulated with, glottal constriction: thus, what or fruit . (This innovation of /t/ glottal stopping may occur in British English as well.) + Flapping: or becomes a flap both after a vowel or and before an unstressed vowel or a syllabic consonant other than , including water , party and model . This results in pairs such as ladder/latter, metal/medal, and coating/coding being pronounced the same. Flapping of or before a full stressed vowel is also possible but only if that vowel begins a new word or morpheme, as in what is it? and twice in not at all . Other rules apply to flapping to such a complex degree in fact that flapping has been analyzed as being required in certain contexts, prohibited in others, and optional in still others. For instance, flapping is prohibited in words like seduce , retail , and monotone , yet optional in impotence . +Both intervocalic and may commonly be realized as (a nasalized alveolar flap) (flapping) or simply , making winter and winner homophones in fast or informal speech. + L-velarization: England's typical distinction between a "clear L" (i.e. ) and a "dark L" (i.e. ) is much less noticeable in nearly all dialects of American English; it is often altogether absent, with all "L" sounds tending to be "dark", meaning having some degree of velarization, perhaps even as dark as (though in the initial position, perhaps less dark than elsewhere among some speakers). The only notable exceptions to this velarization are in some Spanish-influenced American English varieties (such as East Coast Latino English, which typically shows a clear "L" in syllable onsets) and in older, moribund Southern speech, where "L" is clear in an intervocalic environment between front vowels. + Weak vowel merger: The vowel in unstressed syllables generally merges with and so effect is pronounced like affect, and abbot and rabbit rhyme. The quality of the merged vowel varies considerably based on the environment but is typically more open, like [ə], in word-initial or word-final position, but more close, like [ɪ~ɨ], elsewhere. + Raising of pre-voiceless : Many speakers split the sound based on whether it occurs before a voiceless consonant and so in rider, it is pronounced , but in writer, it is raised to (because is a voiceless consonant while is not). Thus, words like bright, hike, price, wipe, etc. with a following voiceless consonant (such as ) use a more raised vowel sound compared to bride, high, prize, wide, etc. Because of this sound change, the words rider and writer , for instance, remain distinct from one another by virtue of their difference in height (and length) of the diphthong's starting point (unrelated to both the letters d and t being pronounced in these words as alveolar flaps ). The sound change also applies across word boundaries, though the position of a word or phrase's stress may prevent the raising from taking place. For instance, a high school in the sense of "secondary school" is generally pronounced ; however, a high school in the literal sense of "a tall school" would be pronounced . The sound change began in the Northern, New England, and Mid-Atlantic regions of the country, and is becoming more common across the nation. + Many speakers in the Inland North, Upper Midwestern, and Philadelphia dialect areas raise before voiced consonants in certain words as well, particularly , and . Hence, words like tiny, spider, cider, tiger, dinosaur, beside, idle (but sometimes not idol), and fire may contain a raised nucleus. The use of , rather than , in such words is unpredictable from the phonetic environment alone, but it may have to do with their acoustic similarity to other words that with before a voiceless consonant, per the traditional Canadian-raising system. Some researchers have argued that there has been a phonemic split in those dialects, and the distribution of the two sounds is becoming more unpredictable among younger speakers. + Many speakers from California, other Western states including those in the Pacific Northwest, and the Upper Midwest realize final as when ("short i") is raised to become ("long ee") before the underlying is converted to , so that coding, for example, is pronounced , homophonous with codeine. + Conditioned /æ/ raising (especially before and ): The raising of the or vowel occurs in specific environments that vary widely from region to region but most commonly before and . With most American speakers for whom the phoneme operates under a somewhat-continuous system, has both a tense and a lax allophone (with a kind of "continuum" of possible sounds between both extremes, rather than a definitive split). In those accents, is overall realized before nasal stops as tenser (approximately ), while other environments are laxer (approximately the standard ); for example, note the vowel sound in for mass, but for man). In the following audio clip, the first pronunciation is the tensed one for the word camp, much more common in American English than the second . +In some American accents, however, specifically those from Baltimore, Philadelphia, and New York City, and are indeed entirely separate (or "split") phonemes, for example, in planet vs. plan it . They are called Mid-Atlantic split-a systems. The vowels move in the opposite direction (high and forward) in the mouth compared to the backed Standard British "broad a", but both a systems are probably related phonologically, if not phonetically since a British-like phenomenon occurs among some older speakers of the eastern New England (Boston) area for whom changes to before alone or when preceded by a homorganic nasal. + + "Short o" before r before a vowel: In typical North American accents (both U.S. and Canada), the historical sequence (a short o sound followed by r and then another vowel, as in orange, forest, moral, and warrant) is realized as , thus further merging with the already-merged (horse–hoarse) set. In the U.S., a small number of words (namely, tomow, sy, sow, bow, and mow) usually contain the sound instead and thus merge with the set (thus, sorry and sari become homophones, both rhyming with starry). + +Some mergers found in most varieties of both American and British English include the following: + Horse–hoarse merger: This merger makes the vowels and before homophones, with homophonous pairs like horse/hoarse, corps/core, for/four, morning/mourning, war/wore, etc. homophones. Many older varieties of American English still keep the sets of words distinct, particularly in the extreme Northeast, the South (especially along the Gulf Coast), and the central Midlands, but the merger is evidently spreading and younger Americans rarely show the distinction. + Wine–whine merger: This produces pairs like wine/whine, wet/whet, Wales/whales, wear/where, etc. homophones, in most cases eliminating , also transcribed , the voiceless labiovelar fricative. However, scatterings of older speakers who do not merge these pairs still exist nationwide, perhaps most strongly in the South. + +Vocabulary + +The process of coining new lexical items started as soon as English-speaking British-American colonists began borrowing names for unfamiliar flora, fauna, and topography from the Native American languages. Examples of such names are opossum, raccoon, squash, moose (from Algonquian), wigwam, and moccasin. American English speakers have integrated traditionally non-English terms and expressions into the mainstream cultural lexicon; for instance, en masse, from French; cookie, from Dutch; kindergarten from German, and rodeo from Spanish. Landscape features are often loanwords from French or Spanish, and the word corn, used in England to refer to wheat (or any cereal), came to denote the maize plant, the most important crop in the U.S. + +Most Mexican Spanish contributions came after the War of 1812, with the opening of the West, like ranch (now a common house style). Due to Mexican culinary influence, many Spanish words are incorporated in general use when talking about certain popular dishes: cilantro (instead of coriander), queso, tacos, quesadillas, enchiladas, tostadas, fajitas, burritos, and guacamole. These words usually lack an English equivalent and are found in popular restaurants. New forms of dwelling created new terms (lot, waterfront) and types of homes like log cabin, adobe in the 18th century; apartment, shanty in the 19th century; project, condominium, townhouse, mobile home in the 20th century; and parts thereof (driveway, breezeway, backyard). Industry and material innovations from the 19th century onwards provide distinctive new words, phrases, and idioms through railroading (see further at rail terminology) and transportation terminology, ranging from types of roads (dirt roads, freeways) to infrastructure (parking lot, overpass, rest area), to automotive terminology often now standard in English internationally. Already existing English words—such as store, shop, lumber—underwent shifts in meaning; others remained in the U.S. while changing in Britain. Science, urbanization, and democracy have been important factors in bringing about changes in the written and spoken language of the United States. From the world of business and finance came new terms (merger, downsize, bottom line), from sports and gambling terminology came, specific jargon aside, common everyday American idioms, including many idioms related to baseball. The names of some American inventions remained largely confined to North America (elevator [except in the aeronautical sense], gasoline) as did certain automotive terms (truck, trunk). + +New foreign loanwords came with 19th and early 20th century European immigration to the U.S.; notably, from Yiddish (chutzpah, schmooze, bupkis, glitch) and German (hamburger, wiener). A large number of English colloquialisms from various periods are American in origin; some have lost their American flavor (from OK and cool to nerd and 24/7), while others have not (have a nice day, for sure); many are now distinctly old-fashioned (swell, groovy). Some English words now in general use, such as hijacking, disc jockey, boost, bulldoze and jazz, originated as American slang. + +American English has always shown a marked tendency to use words in different parts of speech and nouns are often used as verbs. Examples of nouns that are now also verbs are interview, advocate, vacuum, lobby, pressure, rear-end, transition, feature, profile, hashtag, head, divorce, loan, estimate, X-ray, spearhead, skyrocket, showcase, bad-mouth, vacation, major, and many others. Compounds coined in the U.S. are for instance foothill, landslide (in all senses), backdrop, teenager, brainstorm, bandwagon, hitchhike, smalltime, and a huge number of others. Other compound words have been founded based on industrialization and the wave of the automobile: five-passenger car, four-door sedan, two-door sedan, and station-wagon (called an estate car in British English). Some are euphemistic (human resources, affirmative action, correctional facility). Many compound nouns have the verb-and-preposition combination: stopover, lineup, tryout, spin-off, shootout, holdup, hideout, comeback, makeover, and many more. Some prepositional and phrasal verbs are in fact of American origin (win out, hold up, back up/off/down/out, face up to and many others). + +Noun endings such as -ee (retiree), -ery (bakery), -ster (gangster) and -cian (beautician) are also particularly productive in the U.S. Several verbs ending in -ize are of U.S. origin; for example, fetishize, prioritize, burglarize, accessorize, weatherize, etc.; and so are some back-formations (locate, fine-tune, curate, donate, emote, upholster and enthuse). Among syntactical constructions that arose are outside of, headed for, meet up with, back of, etc. Americanisms formed by alteration of some existing words include notably pesky, phony, rambunctious, buddy, sundae, skeeter, sashay and kitty-corner. Adjectives that arose in the U.S. are, for example, lengthy, bossy, cute and cutesy, punk (in all senses), sticky (of the weather), through (as in "finished"), and many colloquial forms such as peppy or wacky. + +A number of words and meanings that originated in Middle English or Early Modern English and that have been in everyday use in the United States have since disappeared in most varieties of British English; some of these have cognates in Lowland Scots. Terms such as fall ("autumn"), faucet ("tap"), diaper ("nappy"; itself unused in the U.S.), candy ("sweets"), skillet, eyeglasses, and obligate are often regarded as Americanisms. Fall for example came to denote the season in 16th century England, a contraction of Middle English expressions like "fall of the leaf" and "fall of the year." Gotten (past participle of get) is often considered to be largely an Americanism. Other words and meanings were brought back to Britain from the U.S., especially in the second half of the 20th century; these include hire ("to employ"), I guess (famously criticized by H. W. Fowler), baggage, hit (a place), and the adverbs overly and presently ("currently"). Some of these, for example, monkey wrench and wastebasket, originated in 19th century Britain. The adjectives mad meaning "angry", smart meaning "intelligent", and sick meaning "ill" are also more frequent in American (and Irish) English than British English. + +Linguist Bert Vaux created a survey, completed in 2003, polling English speakers across the United States about their specific everyday word choices, hoping to identify regionalisms. The study found that most Americans prefer the term sub for a long sandwich, soda (but pop in the Great Lakes region and generic coke in the South) for a sweet and bubbly soft drink, you or you guys for the plural of you (but y'all in the South), sneakers for athletic shoes (but often tennis shoes outside the Northeast), and shopping cart for a cart used for carrying supermarket goods. + +Differences between American and British English + +American English and British English (BrE) often differ at the levels of phonology, phonetics, vocabulary, and, to a much lesser extent, grammar and orthography. The first large American dictionary, An American Dictionary of the English Language, known as Webster's Dictionary, was written by Noah Webster in 1828, codifying several of these spellings. + +Differences in grammar are relatively minor, and do not normally affect mutual intelligibility; these include: typically a lack of differentiation between adjectives and adverbs, employing the equivalent adjectives as adverbs he ran quick/he ran quickly; different use of some auxiliary verbs; formal (rather than notional) agreement with collective nouns; different preferences for the past forms of a few verbs (for example, AmE/BrE: learned/learnt, burned/burnt, snuck/sneaked, dove/dived) although the purportedly "British" forms can occasionally be seen in American English writing as well; different prepositions and adverbs in certain contexts (for example, AmE in school, BrE at school); and whether or not a definite article is used, in very few cases (AmE to the hospital, BrE to hospital; contrast, however, AmE actress Elizabeth Taylor, BrE the actress Elizabeth Taylor). Often, these differences are a matter of relative preferences rather than absolute rules; and most are not stable since the two varieties are constantly influencing each other, and American English is not a standardized set of dialects. + +Differences in orthography are also minor. The main differences are that American English usually uses spellings such as flavor for British flavour, fiber for fibre, defense for defence, analyze for analyse, license for licence, catalog for catalogue and traveling for travelling. Noah Webster popularized such spellings in America, but he did not invent most of them. Rather, "he chose already existing options on such grounds as simplicity, analogy or etymology." Other differences are due to the francophile tastes of the 19th century Victorian era Britain (for example they preferred programme for program, manoeuvre for maneuver, cheque for check, etc.). AmE almost always uses -ize in words like realize. BrE prefers -ise, but also uses -ize on occasion (see: Oxford spelling). + +There are a few differences in punctuation rules. British English is more tolerant of run-on sentences, called "comma splices" in American English, and American English requires that periods and commas be placed inside closing quotation marks even in cases in which British rules would place them outside. American English also favors the double quotation mark ("like this") over the single ('as here'). + +Vocabulary differences vary by region. For example, autumn is used more commonly in the United Kingdom, whereas fall is more common in American English. Some other differences include: aerial (United Kingdom) vs. antenna, biscuit (United Kingdom) vs. cookie/cracker, car park (United Kingdom) vs. parking lot, caravan (United Kingdom) vs. trailer, city centre (United Kingdom) vs. downtown, flat (United Kingdom) vs. apartment, fringe (United Kingdom) vs. bangs, and holiday (United Kingdom) vs. vacation. + +AmE sometimes favors words that are morphologically more complex, whereas BrE uses clipped forms, such as AmE transportation and BrE transport or where the British form is a back-formation, such as AmE burglarize and BrE burgle (from burglar). However, while individuals usually use one or the other, both forms will be widely understood and mostly used alongside each other within the two systems. + +Varieties + +While written American English is largely standardized across the country and spoken American English dialects are highly mutually intelligible, there are still several recognizable regional and ethnic accents and lexical distinctions. + +Regional accents + +The regional sounds of present-day American English are reportedly engaged in a complex phenomenon of "both convergence and divergence": some accents are homogenizing and leveling, while others are diversifying and deviating further away from one another. + +Having been settled longer than the American West Coast, the East Coast has had more time to develop unique accents, and it currently comprises three or four linguistically significant regions, each of which possesses English varieties both different from each other as well as quite internally diverse: New England, the Mid-Atlantic states (including a New York accent as well as a unique Philadelphia–Baltimore accent), and the South. As of the 20th century, the middle and eastern Great Lakes area, Chicago being the largest city with these speakers, also ushered in certain unique features, including the fronting of the vowel in the mouth toward and tensing of the vowel wholesale to . These sound changes have triggered a series of other vowel shifts in the same region, known by linguists as the "Inland North". The Inland North shares with the Eastern New England dialect (including Boston accents) a backer tongue positioning of the vowel (to ) and the vowel (to ) in comparison to the rest of the country. Ranging from northern New England across the Great Lakes to Minnesota, another Northern regional marker is the variable fronting of before , for example, appearing four times in the stereotypical Boston shibboleth Park the car in Harvard Yard. + +Several other phenomena serve to distinguish regional U.S. accents. Boston, Pittsburgh, Upper Midwestern, and Western U.S. accents have fully completed a merger of the vowel with the vowel ( and , respectively): a cot–caught merger, which is rapidly spreading throughout the whole country. However, the South, Inland North, and a Northeastern coastal corridor passing through Rhode Island, New York City, Philadelphia, and Baltimore typically preserve an older cot–caught distinction. For that Northeastern corridor, the realization of the vowel is particularly marked, as depicted in humorous spellings, like in tawk and cawfee (talk and coffee), which intend to represent it being tense and diphthongal: . A split of into two separate phonemes, using different a pronunciations for example in gap versus gas , further defines New York City as well as Philadelphia–Baltimore accents. + +Most Americans preserve all historical sounds, using what is known as a rhotic accent. The only traditional r-dropping (or non-rhoticity) in regional U.S. accents variably appears today in eastern New England, New York City, and some of the former plantation South primarily among older speakers (and, relatedly, some African-American Vernacular English across the country), though the vowel-consonant cluster found in "bird", "work", "hurt", "learn", etc. usually retains its r pronunciation, even in these non-rhotic American accents. Non-rhoticity among such speakers is presumed to have arisen from their upper classes' close historical contact with England, imitating London's r-dropping, a feature that has continued to gain prestige throughout England from the late 18th century onwards, but which has conversely lost prestige in the U.S. since at least the early 20th century. Non-rhoticity makes a word like car sound like cah or source like sauce. + +New York City and Southern accents are the most prominent regional accents of the country, as well as the most stigmatized and socially disfavored. Southern speech, strongest in southern Appalachia and certain areas of Texas, is often identified by Americans as a "country" accent, and is defined by the vowel losing its gliding quality: , the initiation event for a complicated Southern vowel shift, including a "Southern drawl" that makes short front vowels into distinct-sounding gliding vowels. The fronting of the vowels of , , , and tends to also define Southern accents as well as the accents spoken in the "Midland": a vast band of the country that constitutes an intermediate dialect region between the traditional North and South. Western U.S. accents mostly fall under the General American spectrum. + +Below, ten major American English accents are defined by their particular combinations of certain vowel sounds: + +General American + +In 2010, William Labov noted that Great Lakes, Philadelphia, Pittsburgh, and West Coast accents have undergone "vigorous new sound changes" since the mid-nineteenth century onwards, so they "are now more different from each other than they were 50 or 100 years ago", while other accents, like of New York City and Boston, have remained stable in that same time-frame. However, a General American sound system also has some debated degree of influence nationwide, for example, gradually beginning to oust the regional accent in urban areas of the South and at least some in the Inland North. Rather than one particular accent, General American is best defined as an umbrella covering an American accent that does not incorporate features associated with some particular region, ethnicity, or socioeconomic group. Typical General American features include rhoticity, the father–bother merger, Mary–marry–merry merger, pre-nasal "short a" tensing, and other particular vowel sounds. General American features are embraced most by Americans who are highly educated or in the most formal contexts, and regional accents with the most General American native features include North Midland, Western New England, and Western accents. + +Other varieties +Although no longer region-specific, African-American Vernacular English, which remains the native variety of most working- and middle-class African Americans, has a close relationship to Southern dialects and has greatly influenced everyday speech of many Americans, including hip hop culture. Hispanic and Latino Americans have also developed native-speaker varieties of English. The best-studied Latino Englishes are Chicano English, spoken in the West and Midwest, and New York Latino English, spoken in the New York metropolitan area. Additionally, ethnic varieties such as Yeshiva English and "Yinglish" are spoken by some American Orthodox Jews, Cajun Vernacular English by some Cajuns in southern Louisiana, and Pennsylvania Dutch English by some Pennsylvania Dutch people. American Indian Englishes have been documented among diverse Indian tribes. The island state of Hawaii, though primarily English-speaking, is also home to a creole language known commonly as Hawaiian Pidgin, and some Hawaii residents speak English with a Pidgin-influenced accent. American English also gave rise to some dialects outside the country, for example, Philippine English, beginning during the American occupation of the Philippines and subsequently the Insular Government of the Philippine Islands; Thomasites first established a variation of American English in these islands. + +Statistics on usage + +In 2020, about 243 million Americans, aged 5 or above, spoke English at home: a majority of the United States total population of roughly 330 million people. The United States has never had an official language at the federal level, but English is commonly used at the federal level and in states without an official language. Thirty-one of the fifty states, in some cases as part of what has been called the English-only movement, have adopted legislation granting official status to English. Typically only "English" is specified, not a particular variety like American English. (From 1923 to 1969, the state of Illinois recognized its official language as "American", meaning American English.) Puerto Rico is the largest example of a United States territory in which a language other than English – Spanish – is the common language at home, in public, and in government. + +See also + + American and British English spelling differences + Canadian English + Dictionary of American Regional English + International English + International Phonetic Alphabet chart for English dialects + International Phonetic Alphabet chart for the English Language + List of English words from indigenous languages of the Americas + Phonological history of English + Regional accents of English + Transatlantic accent + +Notes + +References + +Bibliography + +Further reading + Bailey, Richard W.

Spalding sporting goods company. He was born and raised in Byron, Illinois, yet graduated from Rockford Central High School in Rockford, Illinois. He played major league baseball between 1871 and 1878. Spalding set a trend when he started wearing a baseball glove. + +After his retirement as a player, Spalding remained active with the Chicago White Stockings as president and part-owner. In the 1880s, he took players on the first world tour of baseball. With William Hulbert, Spalding organized the National League. He later called for the commission that investigated the origins of baseball and falsely credited Abner Doubleday with creating the game. + +He was inducted into the Baseball Hall of Fame in 1939. + +Baseball career + +Player +Having played baseball throughout his youth, Spalding first played competitively with the Rockford Pioneers, a youth team, which he joined in 1865. After pitching his team to a 26–2 victory over a local men's amateur team (the Mercantiles), he was approached at the age of 15 by the Rockford Forest Citys, for whom he played for five years. Following the formation of baseball's first professional organization, the National Association of Professional Base Ball Players (which became known as the National Association, the Association, or NA) in 1871, Spalding joined the Boston Red Stockings (precursor club to the modern Atlanta Braves) and was highly successful; winning 206 games (and losing only 53) as a pitcher and batting .323 as a hitter. + +William Hulbert, principal owner of the Chicago White Stockings, did not like the loose organization of the National Association and the gambling element that influenced it, so he decided to create a new organization, which he dubbed the National League of Baseball Clubs. To aid him in this venture, Hulbert enlisted the help of Spalding. Playing to the pitcher's desire to return to his Midwestern roots and challenging Spalding's integrity, Hulbert convinced Spalding to sign a contract to play for the White Stockings (now known as the Chicago Cubs) in 1876. Spalding then coaxed teammates Deacon White, Ross Barnes and Cal McVey, as well as Philadelphia Athletics players Cap Anson and Bob Addy, to sign with Chicago. This was all done under complete secrecy during the playing season because players were all free agents in those days and they did not want their current club and especially the fans to know they were leaving to play elsewhere the next year. News of the signings by the Boston and Philadelphia players leaked to the press before the season ended and all of them faced verbal abuse and physical threats from the fans of those cities. + +He was "the premier pitcher of the 1870s", leading the league in victories for each of his six full seasons as a professional. During each of those years he was his team's only pitcher. In 1876, Spalding won 47 games as the prime pitcher for the White Stockings and led them to win the first-ever National League pennant by a wide margin. + +In 1877, Spalding began to use a glove to protect his catching hand. People had used gloves previously, but they were not popular, and Spalding himself was skeptical of wearing one at first. However, once he began donning gloves, he influenced other players to do so. + +Spalding retired from playing baseball in 1878 at the age of 27, although he continued as president and part owner of the White Stockings and a major influence on the National League. Spalding's .796 career winning percentage (from an era when teams played about once or twice a week) is the highest ever by a baseball pitcher, .058 ahead of Negro league star Dave Brown's .738. Spalding was the first pitcher to reach 200 wins. + +Organizer and executive +In the months after signing for Chicago, Hulbert and Spalding organized the National League by enlisting the two major teams in the East and the four other top teams in what was then considered to be the West, also known as the jungle. Joining Chicago initially were the leading teams from Cincinnati, Louisville, and St. Louis. The owners of these western clubs accompanied Hulbert and Spalding to New York where they secretly met with owners from New York City, Philadelphia, Hartford, and Boston. Each signed the league's constitution, and the National League was officially born. "Spalding was thus involved in the transformation of baseball from a game of gentlemen athletes into a business and a professional sport." Although the National Association held on for a few more seasons, it was no longer recognized as the premier organization for professional baseball. Gradually, it faded out of existence and was replaced by myriad minor leagues and associations around the country. + +In 1886, with Spalding as president of the franchise, the Chicago White Stockings (today's Chicago Cubs), began holding spring training in Hot Springs, Arkansas, which subsequently has been called the "birthplace" of spring training baseball. The location and the training concept was the brainchild of Spalding and his player/manager Cap Anson, who saw that the city and the natural springs created positives for their players. They first played in an area called the Hot Springs Baseball Grounds. Many other teams followed the concept and began training in Hot Springs and other locations. + +In 1905, after Henry Chadwick wrote an article saying that baseball grew from the British sports of cricket and rounders, Spalding called for a commission to find out the real source of baseball. The commission called for citizens who knew anything about the founding of baseball to send in letters. After three years of searching, on December 30, 1907, Spalding received a letter that (erroneously) declared baseball to be the invention of Abner Doubleday. The commission was biased, as Spalding would not appoint anyone to the commission if they believed the sport was somewhat related to rounders or cricket. Just before the commission issued its findings, in a letter to sportswriter Tim Murnane, Spalding noted, "Our good old American game of baseball must have an American Dad." The project, later called the Mills Commission, concluded that "Base Ball had its origins in the United States" and "the first scheme for playing baseball, according to the best evidence available to date, was devised by Abner Doubleday at Cooperstown, N.Y., in 1839." + +Receiving the archives of Henry Chadwick in 1908, Spalding combined these records with his own memories (and biases) to write America's National Game (published 1911) which, despite its flaws, was probably the first scholarly account of the history of baseball. + +In 1912, Spalding wrote "Neither our wives, our sisters, our daughters, our sweethearts, may play Base Ball on the field... they may play Basket Ball, and achieve laurels; they may play Golf, and receive trophies, but Base Ball is too strenuous for womankind, except as she may take part in grandstands, with applause for the brilliant play, with waiving kerchief to the hero of the three-bagger." + +Businessman +In 1876 while Spalding was playing and organizing the league, Spalding and his brother Walter began a sporting goods store in Chicago, which grew rapidly (14 stores by 1901) and expanded into a manufacturer and distributor of all kinds of sporting equipment. The company became "synonymous with sporting goods" and is still a going concern. + +Spalding Athletic Library + +Spalding, from 1892. +to 1941. +sold books under the name Spalding Athletic Library on many different sports. + +Tour +In 1888–1889, Spalding took a group of major league players around the world to promote baseball and Spalding sporting goods. This was the first-ever world baseball tour. Playing across the western U.S., the tour made stops in Hawaii (although no game was played), New Zealand, Australia, Ceylon, Egypt, Italy, France, and England. The tour returned to grand receptions in New York, Philadelphia, and Chicago. The tour included future Hall of Famers Cap Anson and John Montgomery Ward. + +The tour was also touted by Spalding as a launching point for baseball to reach the global stage. At a celebratory dinner in Manhattan, he celebrated the tour – perhaps prematurely – for establishing “our national game throughout the world.” Following Spalding's statements, Mark Twain proclaimed that the tour “carried the American name to the outermost parts of the earth, and covered it with glory every time.” + +While Spalding and company gushed about their schlep around the world, waxing lyrical about baseball’s future as a global sport, in reality, the tour had very little impact on the sport’s hold overseas. Sports like soccer, rugby, and cricket had already been established in many other countries due to the presence of European imperialism so baseball had a difficult time gaining popularity in these regions. While baseball did reach a wider global audience, it was due to a larger scale diffusion of the sport rather than the efforts of one magnate, like Spalding envisioned. + +While the players were on the tour, the National League instituted new rules regarding player pay that led to a revolt of players, led by Ward, who started the Players' League the following season (1890). The league lasted one year, partially due to the anti-competitive tactics of Spalding to limit its success. The tour and formation of the Player's League is depicted in the 2015 movie Deadball. + +1900 Olympics +In 1900 Spalding was appointed by President McKinley as the USA's Commissioner at that year's Summer Olympic Games. + +Other activities +Spalding had been a prominent member of the Theosophical Society under William Quan Judge. In 1900, Spalding moved to San Diego with his newly acquired second wife, Elizabeth and became a prominent member and supporter of the Theosophical community Lomaland, which was being developed on Point Loma by Katherine Tingley. He built an estate in the Sunset Cliffs area of Point Loma where he lived with Elizabeth for the rest of his life. The Spaldings raised race horses and collected Chinese fine furniture and art. + +The Spaldings had an extensive library which included many volumes on Theosophy, art, and literature. In 1907–1909 he was the driving force behind the development of a paved road, known as the "Point Loma boulevard," from downtown San Diego to Point Loma and Ocean Beach; the road also provided good access to Lomaland. It later provided the basis for California State Route 209. He proposed the project, supervised it on behalf of the city, and paid a portion of the cost out of his own pocket. He joined with George Marston and other civic-minded businessmen to purchase the site of the original Presidio of San Diego, which they developed as a historic park and eventually donated to the city of San Diego. He ran unsuccessfully for the United States Senate in 1910 as a Republican, but lost to eventual winner John D. Works by a vote of 92–21 in the California legislature. He helped to organize the 1915 Panama–California Exposition, serving as second vice-president. + +Death +He died of a stroke on September 9, 1915, in San Diego, one week after his 66th birthday. His ashes were scattered at his request. + +Legacy +He was elected to the Baseball Hall of Fame by the Veterans Committee in 1939, as one of the first inductees from the 19th century at that summer's opening ceremonies.

It was initially developed in 1928 by the International Institute of African Languages and Cultures from a combination of the English alphabet and the International Phonetic Alphabet (IPA). Development was assisted by native speakers of African languages and led by Diedrich Hermann Westermann, who served as director of the organization from 1926 to 1939. The aim of the International Institute of African Languages and Cultures, later renamed the International African Institute (IAI), was to enable people to write for practical and scientific purposes in all African languages without the need of diacritics. + +The Africa Alphabet influenced the development of orthographies of many African languages, serving "as the basis for the transcription" of about 60 by one count. Discussion of how to harmonize these with other systems led to several largely abortive proposals such as the African reference alphabet and the World Orthography. + +Overview +The Africa Alphabet was built from the consonant letters of the English alphabet and the vowel letters, and any additional consonants, of the IPA. Capital forms of IPA letters were invented as necessary. Thus J and Y are pronounced and as in English, while Ɔ, Ɛ and Ŋ are pronounced , and as in the IPA. + +Characters + +See also +African reference alphabet +Latin-script alphabet +Dinka alphabet +ISO 6438 +Pan-Nigerian alphabet +Standard Alphabet by Lepsius +Writing systems of Africa + +Notes + +References +Coulmas, Florian, The Blackwell Encyclopedia of Writing Systems, 1996, Blackwell, Oxford +IIACL, Practical Orthography of African Languages, Revised Edition, London: Oxford University Press, 1930 +Sow, Alfa I., and Mohamed H.

It was one of the most popular games in the 3M Bookshelf games series published in the 1960s, and the only one still published in the United States. + +Description +Acquire is a board game for 2–6 players in which players attempt to earn the most money by developing and merging hotel chains. When a chain in which a player owns stock is acquired by a larger chain, players earn money based on the size of the acquired chain. At the end of the game, all players liquidate their stock in order to determine which player has the most money. It is played with play money, stock certificates, and tiles representing hotels that are arranged on the board. The components of the game have varied over the years. In particular, the tiles have been made from wood, plastic, and cardboard in various editions of the game. + +Set up +Before play begins, the players must decide whether the numbers of players' shares will be public or private information. Keeping this information private can greatly extend the game since players will be less certain of their status, and therefore less willing to end the game. + +Each player receives play cash and a small random set of playing tiles and becomes the founder of a nascent hotel chain by drawing and placing a tile representing a hotel on the board. Tiles are ordered, and correspond to spaces on the board. Position of the starting tiles determines order of play. + +Gameplay +Play consists of placing a tile on the board and optionally buying stock. The placed tile may found a new hotel chain, grow an existing one or merge two or more chains. Chains are sets of edge-wise adjacent tiles. Founders receive a share of stock in new chains. A chain can become "safe", immune to acquisition, by attaining a specified size. Following placement of a tile, the player may then buy a limited number of shares of stock in existing chains. Shares have a market value determined by the size and stature of the hotel chain. At the end of his or her turn, the player receives a new tile to replace the one played. + +When mergers occur, the smaller chain becomes defunct, and its tiles are then part of the acquiring chain. The two largest shareholders in the acquired chain receive cash bonuses; players may sell their shares in the defunct chain, trade them in for shares of the acquiring chain, or keep them. Mergers between 3 or more chains are handled in order from larger to smaller. + +Ending the game +A player during their turn may declare the game at an end if the largest chain exceeds a specified size (about 40% of the board), or all chains on the board are too large to be acquired. When the game ends, shareholder bonuses +are paid to the two largest shareholders of each chain, and players cash out their shares at market price (shares in any defunct chains are worthless). The player with the most money wins. + +Publication history +When Sid Sackson was a child, he played a Milton Bradley gambling-themed board game titled Lotto. When he became a game designer, Sackson reworked the game into a wargame he called Lotto War. In 1962, Sackson and Alex Randolph were commissioned by 3M to start a new games division. When Sackson submitted Lotto War to 3M the following year, he retitled the game Vacation. 3M suggested changing the name to Acquire, and Sackson agreed. The game was test marketed in several U.S. cities in 1963, and production began in 1964 as a part of the 3M Bookshelf games series. + +In 1976, the 3M game division was sold to Avalon Hill and Acquire became part of their bookcase game series. Four years later, Avalon Hill published the computer game Computer Acquire for the PET, Apple II and TRS-80. + +In 1998, Avalon Hill became part of Hasbro. The new owners reissued a slightly revised version of Acquire in 2000, in which the hotel chains were replaced by fictitious corporations, though the actual gameplay was unchanged. Hasbro soon thereafter discontinued it. In the mid-2000s, the game was transferred to a Hasbro subsidiary, Wizards of the Coast (WotC). In 2008, WotC celebrated "50 years of Avalon Hill Games" with the release of a new edition of Acquire, although the game was not yet 50 years old. In 2016, the game was transferred back to the Hasbro games division and republished in 2016 under the Avalon label, with hotels chains reinstated. + +Reception +In The Playboy Winner's Guide to Board Games, game designer Jon Freeman compared Cartel (A Gamut of Games) and Acquire, noting that both were "better games which focus on the joining of companies into conglomerates." Freeman thought Acquire had an edge over Cartel "in the quality of its components [...] Acquires higher price is unquestionably reflected in its packaging and presentation [and deserves] a place in your game library."Games Magazine included Acquire in their "Top 100 Games" in four consecutive years: + In 1980 the editors praised it as a "classic game of getting in on the ground floor" and "proof that you need money to make money", noting that "a delicate sense of timing is important, but greed and a lust for power also help." + In 1981, the editors noted that it "combines the flavors of Monopoly and the stock market" and cautioned that "Since the object is to acquire cash, careful timing of investments (and raids on competitors' chains!) is critical to winning". + In 1982, the editors commented that "Among family games, this is one of the most strategic." + In 1983, the editors commented "Adding to chains increases their value, but you must anticipate mergers, which occur when someone plays the right connecting tile at the right time." + +In the December 1993 edition of Dragon (Issue 200), Allen Varney advised readers to ignore the hotel theme: "Supposedly a game of hotel acquisitions and mergers, this is actually a superb abstract game of strategy and capital." Varney called the game "An early masterpiece from [Sid] Sackson, game historian and one of the great designers of our time." + + Awards +The game was short-listed for the first Spiel des Jahres board game awards in 1979.GAMES magazine inducted Acquire into their buyers' guide Hall of Fame. The magazine's stated criteria for the Hall of Fame encompasses "games that have met or exceeded the highest standards of quality and play value and have been continuously in production for at least 10 years; i.e., classics."Acquire was inducted into the Academy of Adventure Gaming Arts & Design's Hall of Fame, along with game designer Sid Sackson, in 2011.

It is the country's common language and de facto national language; while Australia has no official language, English is the first language of the majority of the population, and has been entrenched as the de facto national language since British settlement, being the only language spoken in the home for 72% of Australians. It is also the main language used in compulsory education, as well as federal, state and territorial legislatures and courts. + +Australian English began to diverge from British and Irish English after the First Fleet established the Colony of New South Wales in 1788. Australian English arose from a dialectal melting pot created by the intermingling of early settlers who were from a variety of dialectal regions of Great Britain and Ireland, though its most significant influences were the dialects of Southeast England. By the 1820s, the native-born colonists' speech was recognisably distinct from speakers in Britain and Ireland. + +Australian English differs from other varieties in its phonology, pronunciation, lexicon, idiom, grammar and spelling. Australian English is relatively consistent across the continent, although it encompasses numerous regional and sociocultural varieties. "General Australian" describes the de facto standard dialect, which is perceived to be free of pronounced regional or sociocultural markers and is often used in the media. + +History +The earliest Australian English was spoken by the first generation of native-born colonists in the Colony of New South Wales from the end of the 18th century. These native-born children were exposed to a wide range of dialects from across the British Isles. Similar to early American English, the process of dialect levelling and koineisation which ensued produced a relatively homogeneous new variety of English which was easily understood by all. Peter Miller Cunningham's 1827 book Two Years in New South Wales described the distinctive accent and vocabulary that had developed among the native-born colonists. + +The dialects of South East England, including most notably the traditional Cockney dialect of London, were particularly influential on the development of the new variety and constituted "the major input of the various sounds that went into constructing" Australian English. All the other regions of England were represented among the early colonists. A large proportion of early convicts and colonists were from Ireland, and spoke Irish as a sole or first language. They were joined by other non-native speakers of English from Scotland and Wales. + +The first of the Australian gold rushes in the 1850s began a large wave of immigration, during which about two percent of the population of the United Kingdom emigrated to the colonies of New South Wales and Victoria. The Gold Rushes brought immigrants and linguistic influences from many parts of the world. An example was the introduction of vocabulary from American English, including some terms later considered to be typically Australian, such as bushwhacker and squatter. This American influence was continued with the popularity of American films from the early 20th century and the influx of American military personnel during World War II; seen in the enduring persistence of such universally-accepted terms as okay and guys. + +The publication of Edward Ellis Morris's Austral English: A Dictionary Of Australasian Words, Phrases And Usages in 1898, which extensively catalogued Australian English vocabulary, started a wave of academic interest and codification during the 20th century which resulted in Australian English becoming established as an endonormative variety with its own internal norms and standards. This culminated in publications such as the 1981 first edition of the Macquarie Dictionary, a major English language dictionary based on Australian usage, and the 1988 first edition of The Australian National Dictionary, a historical dictionary documenting the history of Australian English vocabulary and idiom. + +Phonology and pronunciation + +The most obvious way in which Australian English is distinctive from other varieties of English is through its unique pronunciation. It shares most similarity with New Zealand English. Like most dialects of English, it is distinguished primarily by the phonetic quality of its vowels. + +Vowels + +The vowels of Australian English can be divided according to length. The long vowels, which include monophthongs and diphthongs, mostly correspond to the tense vowels used in analyses of Received Pronunciation (RP) as well as its centring diphthongs. The short vowels, consisting only of monophthongs, correspond to the RP lax vowels. + +There exist pairs of long and short vowels with overlapping vowel quality giving Australian English phonemic length distinction, which is also present in some regional south-eastern dialects of the UK and eastern seaboard dialects in the US. An example of this feature is the distinction between ferry and fairy . + +As with New Zealand English and General American English, the weak-vowel merger is complete in Australian English: unstressed is merged into (schwa), unless it is followed by a velar consonant. Examples of this feature are the following pairings, which are pronounced identically in Australian English: Rosa's and roses, as well as Lennon and Lenin. Other examples are the following pairs, which rhyme in Australian English: abbott with rabbit, and dig it with bigot. + +Most varieties of Australian English exhibit only a partial trap-bath split. The words bath, grass and can't are always pronounced with the "long" of father. Throughout the majority of the country, the "flat" of man is the dominant pronunciation for the a vowel in the following words: dance, advance, plant, example and answer. The exception is the state of South Australia, where a more advanced trap-bath split has taken place, and where the dominant pronunciation of all the preceding words incorporates the "long" of father. + +Consonants +There is little variation in the sets of consonants used in different English dialects but there are variations in how these consonants are used. Australian English is no exception. + +Australian English is uniformly non-rhotic; that is, the sound does not appear at the end of a syllable or immediately before a consonant. As with many non-rhotic dialects, linking can occur when a word that has a final in the spelling comes before another word that starts with a vowel. An intrusive may similarly be inserted before a vowel in words that do not have in the spelling in certain environments, namely after the long vowel and after word final . This can be heard in "law-r-and order", where an intrusive R is voiced between the AW and the A. + +As with North American English, Intervocalic alveolar flapping is a feature of Australian English: prevocalic and surface as the alveolar tap after sonorants other than as well as at the end of a word or morpheme before any vowel in the same breath group. Examples of this feature are that the following pairs are pronounced similarly or identically: latter and ladder, as well as rated and raided. + +Yod-dropping generally occurs after , , , but not after , and . Accordingly, suit is pronounced as , lute as , Zeus as and enthusiasm as . Other cases of and , as well as and , have coalesced to , , and respectively for many speakers. is generally retained in other consonant clusters. + +In common with most varieties of Scottish English and American English, the phoneme is pronounced by older Australians as a "dark" (velarised) l () in almost all positions, unlike other dialects such as Received Pronunciation, Hiberno (Irish) English and most Australians from the Millennial generation onwards, where a light l (i.e. a non-velarised l) is used in many positions. + +The wine–whine merger is complete in Australian English. + +Pronunciation +Differences in stress, weak forms and standard pronunciation of isolated words occur between Australian English and other forms of English, which while noticeable do not impair intelligibility. + +The affixes -ary, -ery, -ory, -bury, -berry and -mony (seen in words such as necessary, mulberry and matrimony) can be pronounced either with a full vowel () or a schwa (). Although some words like necessary are almost universally pronounced with the full vowel, older generations of Australians are relatively likely to pronounce these affixes with a schwa as is typical in British English. Meanwhile, younger generations are relatively likely to use a full vowel. + +Words ending in unstressed -ile derived from Latin adjectives ending in -ilis are pronounced with a full vowel, so that fertile sounds like fur tile rather than rhyming with turtle . + +In addition, miscellaneous pronunciation differences exist when compared with other varieties of English in relation to various isolated words, with some of those pronunciations being unique to Australian English. For example: + As with American English, the vowel in yoghurt and the prefix homo- (as in homosexual or homophobic) are pronounced with rather than ; + Vitamin, migraine and privacy are all pronounced with in the stressed syllable () rather than ; + Dynasty and patronise, by contrast, are usually subject to trisyllabic laxing () like in Britain, alongside US-derived ; + The prefix paedo- (as in paedophile) is pronounced rather than ; + In loanwords, the vowel spelled with is often nativized as the vowel (), as in American English, rather than the vowel (), as in British English. For example, pasta is pronounced , analogous to American English , rather than , as in British English. + Urinal is stressed on the first syllable and with the schwa for I: ; + Harass and harassment are pronounced with the stress on the second, rather than the first syllable; + The suffix -sia (as in Malaysia, Indonesia and Polynesia, but not Tunisia) is pronounced rather than ; + The word foyer is pronounced , rather than ; + Tomato, vase and data are pronounced with instead of : , with being uncommon but acceptable; + Zebra and leisure are pronounced and rather than and , both having disyllabic laxing; + Status varies between British-derived with the vowel and American-derived with the vowel; + Conversely, precedence, precedent and derivatives are mainly pronounced with the vowel in the stressed syllable, rather than : ; + Basil is pronounced , rather than ; + Conversely, cache is usually pronounced , rather than the more conventional ; + Buoy is pronounced as (as in boy) rather than ; + The E in congress and progress is not reduced: ; + Conversely, the unstressed O in silicon, phenomenon and python stands for a schwa: ; + In Amazon, Lebanon and marathon, however, the unstressed O stands for the vowel, somewhat as with American English: ; + The colour name maroon is pronounced with the vowel: . + +Variation + +Relative to many other national dialect groupings, Australian English is relatively homogeneous across the country. Some relatively minor regional differences in pronunciation exist. A limited range of word choices is strongly regional in nature. Consequently, the geographical background of individuals may be inferred if they use words that are peculiar to particular Australian states or territories and, in some cases, even smaller regions. In addition, some Australians speak creole languages derived from Australian English, such as Australian Kriol, Torres Strait Creole and Norfuk. + +Academic research has also identified notable sociocultural variation within Australian English, which is mostly evident in phonology. + +Regional variation +Although Australian English is relatively homogeneous, there are some regional variations. The dialects of English spoken in the various states and territories of Australia differ slightly in vocabulary and phonology. + +Most regional differences are in word usage. Swimming clothes are known as cossies or swimmers in New South Wales, togs in Queensland, and bathers in Victoria, Tasmania, Western Australia and South Australia. What Queensland calls a stroller is usually called a pram in Victoria, Western Australia, South Australia, New South Wales, and Tasmania. + +Preference for some synonymous words also differ between states. Garbage (i.e., garbage bin, garbage truck) dominates over rubbish in New South Wales and Queensland, while rubbish is more popular in Victoria, Tasmania, Western Australia and South Australia. + +Additionally, the word footy generally refers to the most popular football code in an area; that is, rugby league or rugby union depending on the local area, in most of New South Wales and Queensland, and Australian rules football elsewhere. In some pockets of Melbourne & Western Sydney 'football' and more rarely 'footy' will refer to Association football. Beer glasses are also named differently in different states. Distinctive grammatical patterns exist such as the use of the interrogative eh (also spelled ay or aye), which is particularly associated with Queensland. Secret Santa () and Kris Kringle are used in all states, with the former being more common in Queensland. + +South Australia +The most pronounced variation in phonology is between South Australia and the other states and territories. The trap–bath split is more complete in South Australia, in contrast to the other states. Accordingly, words such as dance, advance, plant, example and answer are pronounced with (as in father) far more frequently in South Australia while the older (as in mad) is dominant elsewhere in Australia. L-vocalisation is also more common in South Australia than other states. + +Centring diphthongs +In Western Australian and Queensland English, the vowels in near and square are typically realised as centring diphthongs (), whereas in the other states they may also be realised as monophthongs: . + +Salary–celery merger +A feature common in Victorian English is salary–celery merger, whereby a Victorian pronunciation of Ellen may sound like Alan and Victoria's capital city Melbourne may sound like Malbourne to speakers from other states. There is also regional variation in before (as in school and pool). + +Full-fool allophones +In some parts of Australia, notably Victoria, a fully backed allophone of , transcribed , is common before . As a result, the pairs full/fool and pull/pool differ phonetically only in vowel length for those speakers. The usual allophone for is further forward in Queensland and New South Wales than Victoria. + +Sociocultural variation +The General Australian accent serves as the standard variety of English across the country. According to linguists, it emerged during the 19th century. General Australian is the dominant variety across the continent, and is particularly so in urban areas. The increasing dominance of General Australian reflects its prominence on radio and television since the latter half of the 20th century. + +Recent generations have seen a comparatively smaller proportion of the population speaking with the Broad sociocultural variant, which differs from General Australian in its phonology. The Broad variant is found across the continent and is relatively more prominent in rural and outer-suburban areas. + +A largely historical Cultivated sociocultural variant, which adopted features of British Received Pronunciation and which was commonplace in official media during the early 20th century, had become largely extinct by the onset of the 21st century. + +Australian Aboriginal English is made up of a range of forms which developed differently in different parts of Australia, and are said to vary along a continuum, from forms close to Standard Australian English to more non-standard forms. There are distinctive features of accent, grammar, words and meanings, as well as language use. + +Academics have noted the emergence of numerous ethnocultural dialects of Australian English that are spoken by people from some minority non-English speaking backgrounds. These ethnocultural varieties contain features of General Australian English as adopted by the children of immigrants blended with some non-English language features, such as Afro-Asiatic languages and languages of Asia. Samoan English is also influencing Australian English. Other ethnolects include those of Lebanese and Vietnamese Australians. + +A high rising terminal in Australian English was noted and studied earlier than in other varieties of English. The feature is sometimes called Australian questioning intonation. Research published in 1986, regarding vernacular speech in Sydney, suggested that high rising terminal was initially spread by young people in the 1960s. It found that the high rising terminal was used more than twice as often by young people than older people, and is more common among women than men. In the United Kingdom, it has occasionally been considered one of the variety's stereotypical features, and its spread there is attributed to the popularity of Australian soap operas. + +Vocabulary + +Intrinsic traits + +Australian English has many words and idioms which are unique to the dialect and have been written on extensively. + +Internationally well-known examples of Australian terminology include outback, meaning a remote, sparsely populated area, the bush, meaning either a native forest or a country area in general, and g'day, a greeting. Dinkum, or fair dinkum means "true" or "is that true?", among other things, depending on context and inflection. The derivative dinky-di means "true" or devoted: a "dinky-di Aussie" is a "true Australian". + +Australian poetry, such as "The Man from Snowy River", as well as folk songs such as "Waltzing Matilda", contain many historical Australian words and phrases that are understood by Australians even though some are not in common usage today. + +Australian English, in common with British English, uses the word mate to mean friend, as well as the word bloody as a mild expletive or intensifier. Bloody is taken to be milder in Australia than it is in the UK, where the word is considered profanity. + +Several words used by Australians were at one time used in the United Kingdom but have since fallen out of usage or changed in meaning there. For example, creek in Australia, as in North America, means a stream or small river, whereas in the UK it is typically a watercourse in a marshy area; paddock in Australia means field, whereas in the UK it means a small enclosure for livestock; bush or scrub in Australia, as in North America, means a wooded area, whereas in England they are commonly used only in proper names (such as Shepherd's Bush and Wormwood Scrubs). + +Some elements of Aboriginal languages have been adopted by Australian English—mainly as names for places, flora and fauna (for example dingo) and local culture. Many such are localised, and do not form part of general Australian use, while others, such as kangaroo, boomerang, budgerigar, wallaby and so on have become international. Other examples are cooee and hard yakka. The former is used as a high-pitched call, for attracting attention, (pronounced ) which travels long distances. Cooee is also a notional distance: "if he's within cooee, we'll spot him". Hard yakka means "hard work" and is derived from yakka, from the Jagera/Yagara language once spoken in the Brisbane region. Also of Aboriginal origin is the word bung, from the Sydney pidgin English (and ultimately from the Sydney Aboriginal language), meaning "dead", with some extension to "broken" or "useless". Many towns or suburbs of Australia have also been influenced or named after Aboriginal words. The best-known example is the capital, Canberra, named after a local Ngunnawal language word thought to mean "women's breasts" or "meeting place". + +Litotes, such as "not bad", "not much" and "you're not wrong", are also used. Diminutives and hypocorisms are common and are often used to indicate familiarity. Some common examples are arvo (afternoon), barbie (barbecue), smoko (cigarette break), Aussie (Australian) and Straya (Australia). This may also be done with people's names to create nicknames (other English speaking countries create similar diminutives). For example, "Gazza" from Gary, or "Smitty" from John Smith. The use of the suffix -o originates in , which is both a postclitic and a suffix with much the same meaning as in Australian English. + +In informal speech, incomplete comparisons are sometimes used, such as "sweet as" (as in "That car is sweet as."). "Full", "fully" or "heaps" may precede a word to act as an intensifier (as in "The waves at the beach were heaps good."). This was more common in regional Australia and South Australia but has been in common usage in urban Australia for decades. The suffix "-ly" is sometimes omitted in broader Australian English. For instance, "really good" can become "real good". + +Australia's switch to the metric system in the 1970s changed most of the country's vocabulary of measurement from imperial to metric measures. Since the switch to metric, heights of individuals are listed in centimetres on official documents and distances by road on signs are listed in terms of kilometres and metres. + +Comparison with other varieties + +Where British and American English vocabulary differs, sometimes Australian English shares a usage with one of those varieties, as with petrol (AmE: gasoline) and mobile phone (AmE: cellular phone) which are shared with British English, or truck (BrE: lorry) and eggplant (BrE: aubergine) which are shared with American English. + +In other circumstances, Australian English sometimes favours a usage which is different from both British and American English as with: + +Differences exist between Australian English and other varieties of English, where different terms can be used for the same subject or the same term can be ascribed different meanings.

Grammatical differences between varieties of English are minor relative to differences in phonology and vocabulary and do not generally affect intelligibility. Examples of grammatical differences between Australian English and other varieties include: +Collective nouns are generally singular in construction, e.g., the government was unable to decide as opposed to the government were unable to decide or the group was leaving as opposed to the group were leaving. This is in common with American English. +Australian English has an extreme distaste for the modal verbs shall (in non-legal contexts), shan't and ought (in place of will, won't and should respectively), which are encountered in British English. However, shall is found in the Australian Constitution, Acts of Parliament, and other formal or legal documents such as contracts. +Using should with the same meaning as would, e.g. I should like to see you, encountered in British English, is almost never encountered in Australian English. +River follows the name of the river in question, e.g., Brisbane River, rather than the British convention of coming before the name, e.g., River Thames. This is also the case in North American and New Zealand English. In South Australian English however, the reverse applies when referring to the following three rivers: Murray, Darling and Torrens. The Derwent in Tasmania also follows this convention. +While prepositions before days may be omitted in American English, i.e., She resigned Thursday, they are retained in Australian English: She resigned on Thursday. This is shared with British English. +The institutional nouns hospital and university do not take the definite article: She's in hospital, He's at university. This is in contrast to American English where the is required: In the hospital, At the university. +On the weekend is used in favour of the British at the weekend which is not encountered in Australian English. +Ranges of dates use to, i.e., Monday to Friday, rather than Monday through Friday. This is shared with British English and is in contrast to American English. +When speaking or writing out numbers, and is always inserted before the tens, i.e., one hundred and sixty-two rather than one hundred sixty-two. This is in contrast to American English, where the insertion of and is acceptable but nonetheless either casual or informal. +The preposition to in write to (e.g. "I'll write to you") is always retained, as opposed to American usage where it may be dropped. +Australian English does not share the British usage of read (v) to mean "study" (v). Therefore, it may be said that "He studies medicine" but not that "He reads medicine". +When referring to time, Australians will refer to 10:30 as half past ten and do not use the British half ten. Similarly, a quarter to ten is used for 9:45 rather than (a) quarter of ten, which is sometimes found in American English. +Australian English does not share the British English meaning of sat to include sitting or seated. Therefore, uses such as I've been sat here for an hour are not encountered in Australian English. +To have a shower or have a bath are the most common usages in Australian English, in contrast to American English which uses take a shower and take a bath. +The past participle of saw is sawn (e.g. sawn-off shotgun) in Australian English, in contrast to the American English sawed. +The verb visit is transitive in Australian English. Where the object is a person or people, American English also uses visit with, which is not found in Australian English. +An outdoor event which is cancelled due to inclement weather is rained out in Australian English. This is in contrast to British English where it is said to be rained off. +In informal speech, sentence-final but may be used, e.g. "I don't want to go but" in place of "But I don't want to go". This is also found in Scottish English. +In informal speech, the discourse markers yeah no (or yeah nah) and no yeah (or nah yeah) may be used to mean "no" and "yes" respectively. + +Spelling and style +As in all English-speaking countries, there is no central authority that prescribes official usage with respect to matters of spelling, grammar, punctuation or style. + +Spelling + +There are several dictionaries of Australian English which adopt a descriptive approach. The Macquarie Dictionary is most commonly used by universities, governments and courts as the standard for Australian English spelling. The Australian Oxford Dictionary is another commonly-used dictionary of Australian English. + +Australian spelling is significantly closer to British than American spelling, as it did not adopt the systematic reforms promulgated in Noah Webster's 1828 Dictionary. Notwithstanding, the Macquarie Dictionary often lists most American spellings as acceptable secondary variants. + +The minor systematic differences which occur between Australian and American spelling are summarised below: + French-derived words which in American English end with or, such as color, honor, behavior and labor, are spelt with our in Australian English: colour, honour, behaviour and labour. Exceptions are the Australian Labor Party and some (especially South Australian) placenames which use Harbor, notably Victor Harbor. + Words which in American English end with ize, such as realize, recognize and apologize are spelt with ise in Australian English: realise, recognise and apologise. The British Oxford spelling, which uses the ize endings, remains a minority variant. The Macquarie Dictionary says that the -ise form as opposed to -ize sits at 3:1. The sole exception to this is capsize, which is used in all varieties. + Words which in American English end with yze, such as analyze, paralyze and catalyze are spelt with yse in Australian English: analyse, paralyse and catalyse. + French-derived words which in American English end with er, such as fiber, center and meter are spelt with re in Australian English: fibre, centre and metre (the unit of measurement only, not physical devices; so gasometer, voltmeter). + Words which end in American English end with log, such as catalog, dialog and monolog are usually spelt with logue in Australian English: catalogue, dialogue and monologue; however, the Macquarie Dictionary lists the log spelling as the preferred variant for analog. + A double-consonant l is retained in Australian English when adding suffixes to words ending in l where the consonant is unstressed, contrary to American English. Therefore, Australian English favours cancelled, counsellor, and travelling over American canceled, counselor and traveling. + Where American English uses a double-consonant ll in the words skillful, willful, enroll, distill, enthrall, fulfill and installment, Australian English uses a single consonant: skilful, wilful, enrol, distil, enthral, fulfil and instalment. However, the Macquarie Dictionary has noted a growing tendency to use the double consonant. + The American English defense and offense are spelt defence and offence in Australian English. + In contrast with American English, which uses practice and license for both nouns and verbs, practice and licence are nouns while practise and license are verbs in Australian English. + Words with ae and oe are often maintained in words such as oestrogen and paedophilia, in contrast to the American English practice of using e alone (as in estrogen and pedophilia). The Macquarie Dictionary has noted a shift within Australian English towards using e alone, and now lists some words such as encyclopedia, fetus, eon or hematite with the e spelling as the preferred variant and hence Australian English varies by word when it comes to these sets of words. + +Minor systematic difference which occur between Australian and British spelling are as follows: + Words often ending in eable in British English end in able in Australian English. Therefore, Australian English favours livable over liveable, sizable over sizeable, movable over moveable, etc., although both variants are acceptable. + Words often ending in eing in British English end in ing in Australian English. Therefore, Australian English favours aging over ageing, or routing over routeing, etc., although both variants are acceptable. + Words often ending in mme in British English end in m in Australian English. Therefore, Australian English favours program over programme (in all contexts) and aerogram over aerogramme, although both variants are acceptable. Similar to Canada, New Zealand and the United States, (kilo)gram is the only spelling. + +Other examples of individual words where the preferred spelling is listed by the Macquarie Dictionary as being different from current British spellings include analog as opposed to analogue, guerilla as opposed to guerrilla, verandah as opposed to veranda, burqa as opposed to burka, pastie (noun) as opposed to pasty, neuron as opposed to neurone, hicup as opposed to hicough, annex as opposed to annexe, raccoon as opposed to racoon etc. Unspaced forms such as onto, anytime, alright and anymore are also listed as being equally as acceptable as their spaced counterparts. + +There is variation between and within varieties of English in the treatment of -t and -ed endings for past tense verbs. The Macquarie Dictionary does not favour either, but it suggests that leaped, leaned or learned (with -ed endings) are more common but spelt and burnt (with -t endings) are more common. + +Different spellings have existed throughout Australia's history. What are today regarded as American spellings were popular in Australia throughout the late 19th and early 20th centuries, with the Victorian Department of Education endorsing them into the 1970s and The Age newspaper until the 1990s. This influence can be seen in the spelling of the Australian Labor Party and also in some place names such as Victor Harbor. The Concise Oxford English Dictionary has been attributed with re-establishing the dominance of the British spellings in the 1920s and 1930s. For a short time during the late 20th century, Harry Lindgren's 1969 spelling reform proposal (Spelling Reform 1 or SR1) gained some support in Australia and was adopted by the Australian Teachers' Federation. + +Punctuation and style +Prominent general style guides for Australian English include the Cambridge Guide to Australian English Usage, the Australian Government Style Manual (formerly the Style Manual: For Authors, Editors and Printers), the Australian Handbook for Writers and Editors and the Complete Guide to English Usage for Australian Students. + +Both single and double quotation marks are in use, with single quotation marks preferred for use in the first instance, with double quotation marks reserved for quotes of speech within speech. Logical (as opposed to typesetter's) punctuation is preferred for punctuation marks at the end of quotations. For instance, Sam said he 'wasn't happy when Jane told David to "go away"'. is used in preference to Sam said he "wasn't happy when Jane told David to 'go away.'" + +The DD/MM/YYYY date format is followed and the 12-hour clock is generally used in everyday life (as opposed to service, police, and airline applications). + +With the exception of screen sizes, metric units are used in everyday life, having supplanted imperial units upon the country's switch to the metric system in the 1970s, although imperial units persist in casual references to a person's height. Tyre and bolt sizes (for example) are defined in imperial units where appropriate for technical reasons. + +In betting, decimal odds are used in preference to fractional odds, as used in the United Kingdom, or moneyline odds in the United States. + +Keyboard layout +There are two major English language keyboard layouts, the United States layout and the United Kingdom layout. Keyboards and keyboard software for the Australian market universally uses the US keyboard layout, which lacks the pound (£), euro and negation symbols and uses a different layout for punctuation symbols from the UK keyboard layout. + +See also + + The Australian National Dictionary + Australian English vocabulary + New Zealand English + South African English + Zimbabwean English + Falkland Islands English + Diminutives in Australian English + International Phonetic Alphabet chart for English dialects + Strine + +References + +Citations + +Works cited + +Further reading + + + Mitchell, Alexander G.

The Boeing 757-223 aircraft serving the flight was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the Pentagon in Arlington County, Virginia, killing all 64 aboard and another 125 in the building. + +Flight 77 became airborne at 08:20. Thirty-one minutes after takeoff, the attackers stormed the cockpit and forced the passengers and crew to the rear of the cabin, threatening the hostages but initially sparing all of them. Lead hijacker Hani Hanjour assumed control of the aircraft after having undergone extensive flight training as part of his preparation for the attack. In the meantime, two people aboard discreetly made phone calls to family members and relayed information on the situation without the knowledge of their assailants. + +Hanjour flew the airplane into the west side of the Pentagon at 09:37 ET. Many people witnessed the impact, and news sources began reporting on the incident within minutes, but no clear footage of the crash itself is available to the public. The 757 severely damaged an area of the Pentagon and caused a large fire that took several days to extinguish. By 10:10 a.m., the damage inflicted by the plane as well as the ignited jet fuel led to a localized collapse of the Pentagon's western flank, followed forty minutes later by another five stories of the structure. Flight 77 was the third of four passenger jets to be commandeered by terrorists that morning, and the last to reach a target intended by al-Qaeda. The hijacking was to be coordinated with that of United Airlines Flight 93, which was flown in the direction of Washington, D.C., the U.S. capital. The terrorists on Flight 93 had their sights set on a federal government building not far from the Pentagon, but were forced to crash the plane in a Pennsylvania field when the passengers fought for control after being alerted to the previous suicide attacks, including Flight 77's. + +The damaged sections of the Pentagon were rebuilt in 2002, with occupants moving back into the completed areas that August. The 184 victims of the attack are memorialized in the Pentagon Memorial adjacent to the crash site. The park contains a bench for each of the victims, arranged according to their year of birth. + +Background +The flight was commandeered as part of the September 11 attacks. The attacks themselves cost somewhere in the region of $400,000 and $500,000 to execute, but the source of this financial support remains unknown. Led by Khalid Sheikh Mohammed, who was described as being the "principal architect" of the attacks in the 9/11 Commission Report, al-Qaeda was motivated by several factors, not least of which was anti-Americanism and anti-Western sentiment. Because al-Qaeda only had the resources to commandeer four passenger jets, there was disagreement between Mohammed and Osama bin Laden over which targets should be prioritized. Mohammed favored striking the Twin Towers of the World Trade Center complex in New York City, while bin-Laden was bent on toppling the United States federal government, a goal he believed could be accomplished by destroying the Pentagon, the White House and the United States Capitol. Though bin Laden himself expressed a preference for the destruction of the White House over the Capitol, his subordinates disagreed, citing its difficulty in striking from the air. Hani Hanjour―likely while in the presence of fellow Flight 77 accomplice Nawaf al-Hazmi―scoped out the DMV on July 20, 2001 by renting a plane and taking a practice flight from Fairfield, New Jersey to Gaithersburg, Maryland in order to determine the feasibility of each of the possible candidates. + +In the end, 19 terrorists participated in the attacks against the United States, consisting of three groups of five men each and one group of four. The nine hijackers on Flight 77 and United Airlines Flight 93 were assigned the task of striking governmental structures in or near the national capital of Washington, D.C., and as such, the objective was for the two hijackings to be coordinated insofar as both planes being aimed towards targets in the Washington metropolitan area. Significant complications faced by the four terrorists on Flight 93 ensured that Flight 77 was the only one to successfully attack a target intended by al-Qaeda when it struck the Pentagon in Arlington County, Virginia at 09:37, while a passenger uprising forced the hijackers aboard Flight 93 to crash the plane in rural Pennsylvania. + +Regardless, the degree of coordination between Flight 77 and Flight 93 was evidently less than that of American Airlines Flight 11 and United Airlines Flight 175, the two airliners that were flown into the Twin Towers of the World Trade Center 17 minutes apart in a joint attack on New York City. Flights 11 and 175 both departed from Logan International Airport in Boston for Los Angeles International Airport, and crashed into targets that stood next to each other, in contrast to the Pentagon and the federal government building Flight 93 was set to crash into, which were simply located in the same general area. + +One noteworthy difference between the attacks in the National Capital Region and those in New York is that the teams on Flights 77 and 93 did not follow suit with their counterparts on Flights 11 and 175 by booking planes from the same airport with the same California destination in mind. Flight 77's group hijacked a plane out of Dulles International Airport in Virginia, conveniently situated near the Pentagon and consequently the capital, on a flight path destined for LAX. Conversely, Flight 93 departed from Newark International Airport in New Jersey, nearly 200 miles northeast of D.C., bound for San Francisco International Airport. There was also no contact between Hanjour and Flight 93 hijacker pilot Ziad Jarrah on the day of the attacks, whereas Mohamed Atta and Marwan al-Shehhi spoke over the phone while preparing to board their respective flights, apparently to confirm the attacks were ready to begin. + +The reason why al-Qaeda selected four planes from three airports instead of two airports remains unknown, but it is believed that the act of hijacking two planes on the same flight path would have enabled better coordination between the teams on Flight 11 and Flight 175, both of which clearly succeeded, unlike Flight 77 and Flight 93’s only partially successful attack on the U.S. government. + +Hijackers + +The hijackers on American Airlines Flight77 were five Saudi men between the ages of 20 and 29. They were led by Hanjour, who piloted the aircraft into the Pentagon. Hanjour first arrived in the United States in 1990. + +Hanjour trained at the CRM Airline Training Center in Scottsdale, Arizona, earning his FAA commercial pilot's certificate in April 1999. He had wanted to be a commercial pilot for Saudia but was rejected when he applied to the civil aviation school in Jeddah in 1999. Hanjour's brother later explained that, frustrated at not finding a job, Hanjour "increasingly turned his attention toward religious texts and cassette tapes of militant Islamic preachers." Hanjour returned to Saudi Arabia after being certified as a pilot, but left again in late 1999, telling his family he was going to the United Arab Emirates to work for an airline. Hanjour likely went to Afghanistan, where Al-Qaeda recruits were screened for special skills they might have. Already having selected the Hamburg cell members, Al Qaeda leaders selected Hanjour to lead the fourth team of hijackers. + +In December 2000, Hanjour arrived in San Diego, joining "muscle" hijackers Nawaf al-Hazmi and Khalid al-Mihdhar, who had been there since January of that year. Alec Station, the CIA's unit dedicated to tracking Osama bin Laden, had discovered that al-Hazmi and al-Mihdhar had multiple-entry visas to the United States. An FBI agent inside the unit and his supervisor Mark Rossini (Former Federal Bureau of Investigation Supervisory Agent) sought to alert FBI headquarters, but the CIA officer supervising Rossini at Alec Station rebuffed him on the grounds that the FBI lacked jurisdiction. + +Soon after arriving in San Diego, Hanjour and Hazmi left for Mesa, Arizona, where Hanjour began refresher training at Arizona Aviation. In April 2001, they relocated to Falls Church, Virginia, where they awaited the arrival of the remaining "muscle" hijackers. One of these men, Majed Moqed, arrived on May 2, 2001, with Flight175 hijacker Ahmed al-Ghamdi from Dubai at Dulles International Airport. They moved into an apartment with Hazmi and Hanjour. + +On May 21, 2001, Hanjour rented a room in Paterson, New Jersey, where he stayed with other hijackers through the end of August. The last Flight77 "muscle" hijacker, Salem al-Hazmi, arrived on June 29, 2001, with Abdulaziz al-Omari (a hijacker of Flight11) at John F. Kennedy International Airport from the United Arab Emirates. They stayed with Hanjour. + +Hanjour received ground instruction and did practice flights at Air Fleet Training Systems in Teterboro, New Jersey, and at Caldwell Flight Academy in Fairfield, New Jersey. Hanjour moved out of the room in Paterson and arrived at the Valencia Motel in Laurel, Maryland, on September 2, 2001. While in Maryland, Hanjour and fellow hijackers trained at Gold's Gym in Greenbelt. On September 10, he completed a certification flight, using a terrain recognition system for navigation, at Congressional Air Charters in Gaithersburg, Maryland. + +On September 10 Nawaf al-Hazmi, accompanied by other hijackers, checked into the Marriott in Herndon, Virginia, near Dulles Airport. + +Suspected accomplices + +According to a U.S. State Department cable leaked in the WikiLeaks dump in February 2010, the FBI has investigated another suspect, Mohammed al-Mansoori. He had associated with three Qatari citizens who flew from Los Angeles to London (via Washington) and Qatar on the eve of the attacks, after allegedly surveying the World Trade Center and the White House. U.S. law enforcement officials said the data about the four men was "just one of many leads that were thoroughly investigated at the time and never led to terrorism charges." An official added that the three Qatari citizens had never been questioned by the FBI. Eleanor Hill, the former staff director for the congressional joint inquiry on the September 11 attacks, said the cable reinforces questions about the thoroughness of the FBI's investigation. She also said that the inquiry concluded the hijackers had a support network that helped them in different ways. + +The three Qatari men were booked to fly from Los Angeles to Washington on September 10, 2001, on the same plane that was hijacked and piloted into the Pentagon on the following day. Instead, they flew from Los Angeles to Qatar, via Washington and London. While the cable said Mansoori was currently under investigation, U.S. law enforcement officials said there was no active investigation of him or of the Qatari citizens mentioned in the cable. + +Flight + +The aircraft involved in the hijacking was a Boeing 757-223 (registration The aircraft had its first flight on April 25, 1991 and was delivered to American Airlines on May 8, 1991. The crew included Captain Charles Burlingame (51) (a Naval Academy graduate and former fighter pilot), First Officer David Charlebois (39), purser Renee May and flight attendants Michele Heidenberger, Jennifer Lewis and Kenneth Lewis. The capacity of the aircraft was 188 passengers, but with 58 passengers on September 11, the load factor was 33 percent. American Airlines said Tuesdays were the least-traveled day of the week, with the same load factor seen on Tuesdays in the previous three months for Flight77. Passenger Barbara Olson, whose husband Theodore Olson served as the 42nd Solicitor General of the United States, was en route to a recording of the TV show Politically Incorrect. A group of three 11-year-old children, their chaperones, and two National Geographic Society staff members were also on board, embarking on an educational trip west to the Channel Islands National Marine Sanctuary near Santa Barbara, California. Former Georgetown University basketball coach John Thompson had originally booked a ticket on Flight77. As he would tell the story many times in the following years, including a September 12, 2011 interview on Jim Rome's radio show, he had been scheduled to appear on that show on September 12, 2001. Thompson was planning to be in Las Vegas for a friend's birthday on September 13, and initially insisted on traveling to Rome's Los Angeles studio on the 11th. However, this did not work for the show, which wanted him to travel on the day of the show. After a Rome staffer personally assured Thompson he would be able to travel from Los Angeles to Las Vegas immediately after the show, Thompson changed his travel plans. He would later feel the impact from the crash at his home near the Pentagon. + +Boarding and departure +On the morning of September 11, 2001, the five hijackers arrived at Washington Dulles International Airport. At 07:15 AM ET, Khalid al-Mihdhar and Majed Moqed checked in at the American Airlines ticket counter for Flight77, arriving at the passenger security checkpoint a few minutes later at 07:18. Both men set off the metal detector and were put through secondary screening. Moqed continued to set off the alarm, so he was searched with a hand wand. The Hazmi brothers checked in together at the ticket counter at 07:29. Hani Hanjour checked in separately and arrived at the passenger security checkpoint at 07:35. Hanjour was followed minutes later at the checkpoint by Salem and Nawaf al-Hazmi, who also set off the metal detector's alarm. The screener at the checkpoint never resolved what set off the alarm. As seen in security footage later released, Nawaf al-Hazmi appeared to have an unidentified item in his back pocket. Utility knives up to four inches were permitted at the time by the Federal Aviation Administration (FAA) as carry-on items. The passenger security checkpoint at Dulles International Airport was operated by Argenbright Security, under contract with United Airlines. + +The hijackers were all selected for extra screening of their checked bags. Hanjour, al-Mihdhar, and Moqed were chosen by the Computer Assisted Passenger Prescreening System (CAPPS) criteria, while the brothers Nawaf and Salem al-Hazmi were selected because they did not provide adequate identification and were deemed suspicious by the airline check-in agent. Hanjour, Mihdhar, and Nawaf al-Hazmi did not check any bags for the flight. Checked bags belonging to Moqed and Salem al-Hazmi were held until they boarded the aircraft. + +Flight 77 was scheduled to depart for Los Angeles at 08:10; 58 passengers boarded through Gate D26, including the five hijackers. The 53 other passengers on board excluding the hijackers were 26 men, 22 women, and five children ranging in age from three to eleven. On the flight, Hani Hanjour was seated up front in 1B, while Salem and Nawaf al-Hazmi were likewise seated in first class, in seats 5E and 5F. Majed Moqed and Khalid al-Mihdhar were seated farther back in 12A and 12B, in economy class. Flight77 left the gate on time and took off from Runway 30 at Dulles at 08:20. The attacks were already underway by this point, as American Airlines Flight 11 had been hijacked six minutes earlier. Shortly after Flight 77 became airborne, FAA flight controller Danielle O'Brien made a routine handoff of the flight to a colleague at the FAA's Indianapolis Center. For reasons she couldn't explain and would never fully understand, O'Brien didn't use one of her normal sendoffs to the pilots: "Good day," or "Have a nice flight." Instead, she wished them, "Good luck." + +Flight 77 reached its assigned cruising altitude of at 8:46 a.m., four minutes after the hijacking of United Airlines Flight 175 commenced and the very same minute Flight 11 crashed into the North Tower of the World Trade Center. The final communication between Flight 77 and controllers on the ground occurred four minutes later at 08:50:51, as Hanjour and his team prepared to strike. + +Hijacking + +The terrorists launched their assault at 08:51, by which point the North Tower had been on fire for around five minutes and Flight 175 was within 12 minutes of striking the South Tower. Flight 93 had also become airborne from Newark at 08:42, but had been delayed on the runway for as long as 42 minutes and would not be seized until 09:28, ruining al-Qaeda's plan to harmonize its takeover with Flight 77's. Three minutes after the hijacking began, according to the commission, the attackers on Flight 77 were in full control of the aircraft. The modus operandi of Hanjour’s group was in stark contrast to the other three teams, in that while the victims were threatened with knives and box cutters, there were no reports of any injuries or deaths prior to the crash; both pilots were spared when the cockpit was breached, and the use of chemical weapons or bomb threats was not reported by either of the two people who made phone calls from the rear of the cabin. At 08:54, as the plane flew in the vicinity over Pike County, Ohio, it began deviating from its normal assigned flight path and turned south. Two minutes later, the plane's transponder was switched off. The flight's autopilot was promptly engaged and set on a course heading eastbound towards Washington, D.C. + +The FAA was aware at this point there was an emergency on board the airplane. After learning of a second hijacking involving an American Airlines aircraft and the hijacking of a United Airlines jet, American Airlines' executive vice president Gerard Arpey ordered a nationwide ground stop for the airline. For several minutes, Indianapolis Air Route Traffic Control Center and dispatchers for American Airlines made several failed attempts to contact the hijacked airliner, giving up just as Flight 175 flew into the World Trade Center's South Tower at 09:03. The plane had been flying over an area of limited radar coverage at the time of its hijacking. With air controllers unable to contact the flight by radio, an Indianapolis official declared that it had possibly crashed at 09:09, twenty-eight minutes before it actually did. Sometime between 09:17 and 09:22, Hanjour broadcast a deceptive announcement via the cabin’s public address system, advising those aboard that the plane was being hijacked and that their best chance of survival was by not resisting. This tactic was used on Flight 11 and on Flight 93 with the aim of deceiving the passengers and crew into believing the plan was to land the plane after securing a ransom; in both cases, however, the terrorists’ understanding of the internal communication systems used aboard aircraft was evidently not as good as Hanjour's, as they keyed the wrong microphone and unintentionally allowed controllers on the ground to eavesdrop. + +Calls +Two people on board the aircraft made a total of three phone calls to contacts on the ground. At 09:12, flight attendant Renee May made a phone call lasting just under two minutes to her mother, Nancy May, in Las Vegas. During the phone call, she made the erroneous claim that "six persons" had forced "us" to the rear of the airplane, but did not explain whether the people crowded together were crew members, passengers, or both. May asked her mother to contact American Airlines, which she and her husband promptly did, although the company was well-aware of the hijacking by this point. + +At 09:16, Barbara Olson made a call to her husband Ted, quietly explaining that the plane had been hijacked and that those responsible were armed with knives and box cutters. She revealed that everyone, including the pilots, had been moved to the back of the cabin and that the call was being made without the knowledge of the hostage takers. The connection dropped a minute into the conversation. Theodore Olson contacted the command center at the Department of Justice, and tried unsuccessfully to contact Attorney General John Ashcroft. Barbara Olson called again five minutes later, informing her husband of the announcement Hanjour―"the pilot"―made over the loudspeaker, and asked him, "What do I tell the pilot to do?" Inquired of her whereabouts, Barbara replied saying that they were flying low over a residential area. In the background, Ted overheard another passenger mentioning that the plane was flying northeast. He then made his wife aware of the suicide attacks on the World Trade Center, causing her to go quiet; Ted wondered if this meant she had been shocked into silence. After expressing their feelings and reassuring one another, the call cut off for the last time, at 9:26 a.m. + +Crash + + At 9:29 a.m., one minute after Flight 93 was hijacked, the terrorists aboard Flight 77 disengaged the autopilot and took manual control of the plane. Turning and descending rapidly as it made its final approach toward Washington, the airplane was detected again on radar screens by controllers at Dulles, who mistook it for a military fighter at first glance due to its high speed and maneuvering. + +While Flight77 was west-southwest of the Pentagon in Arlington County, Virginia, it made a 330-degree spiral turn clockwise. By the end of the revolution, the 757 was descending , pointed toward the Pentagon and downtown Washington. Advancing the throttles to full power, Hanjour rapidly began diving toward his target. The wings clipped five street lights as the plane flew level above the ground, while the right wing in particular struck a portable generator, creating a smoke trail seconds before smashing into the Pentagon. + +Flying at a speed of over the Navy Annex Building adjacent to Arlington National Cemetery, Flight77 crashed into the Pentagon's western flank at 09:37:46. The plane struck the establishment at the first-floor level and was rolled slightly to the left, with the right wing elevated as it crashed. The front part of the fuselage immediately disintegrated upon impact, while the mid and tail sections continued moving for another fraction of a second, with tail section debris penetrating farthest into the building. In total, the aircraft took eight-tenths of a second to pass through the three outermost of the structure's five rings and unleashed a fireball that rose above the building. The 64 people aboard the flight were killed instantly, while a further 125 people in the Pentagon were either killed outright or fatally injured. + +In the minutes leading up to the crash, Reagan Airport controllers had asked a passing Air National Guard Lockheed C-130 Hercules to identify and follow the aircraft. The pilot, Lieutenant Colonel Steven O'Brien, told them he believed it was either a Boeing757 or 767, observing that its silver fuselage meant it was most likely an American Airlines jet. O'Brien mentioned having difficulty picking out the airplane in the "East Coast haze", but moments later reported seeing a "huge" fireball. His initial assumption as he approached the crash site was that the plane had simply hit the ground, but upon closer inspection he saw the damage done to the Pentagon's west side and relayed to Reagan control, "Looks like that aircraft crashed into the Pentagon, sir." + +At the time of the attacks, approximately 18,000 people worked in the Pentagon, 4,000 fewer than before renovations began in 1998. The section of the Pentagon that was struck, which had recently been renovated at a cost of $250million (~$ in ), housed the Naval Command Center. + +The fatalities in the Pentagon included 55 military personnel and 70 civilians. Of those 125 killed, 92 were on the first floor, 31 were on the second floor, and two were on the third. Seven Defense Intelligence Agency civilian employees were killed while the Office of the Secretary of Defense lost one contractor. The U.S. Army suffered 75 fatalities53 civilians (47 employees and six contractors) and 22 soldierswhile the U.S. Navy suffered 42 fatalitiesnine civilians (six employees and three contractors) and 33 sailors. Lieutenant General Timothy Maude, an Army deputy chief of staff, was the highest-ranking military officer killed at the Pentagon; also killed was retired Rear Admiral Wilson Flagg, a passenger on the plane. LT Mari-Rae Sopper, JAGC, USNR, was also on board the flight, and was the first Navy Judge Advocate ever to be killed in action. Another 106 were injured on the ground and were treated at area hospitals. + +On the side where the plane hit, the Pentagon is bordered by Interstate 395 and Washington Boulevard. Motorist Mary Lyman, who was on I-395, saw the airplane pass over at a "steep angle toward the ground and going fast" and then saw the cloud of smoke from the Pentagon. Omar Campo, another witness, was on the other side of the road: + +Afework Hagos, a computer programmer, was on his way to work and stuck in a traffic jam near the Pentagon when the airplane flew over. "There was a huge screaming noise and I got out of the car as the plane came over. Everybody was running away in different directions. It was tilting its wings up and down like it was trying to balance. It hit some lampposts on the way in." Daryl Donley witnessed the crash and took some of the first photographs of the site. + +USA Today reporter Mike Walter was driving on Washington Boulevard when he witnessed the crash: + +Terrance Kean, who lived in a nearby apartment building, heard the noise of loud jet engines, glanced out his window, and saw a "very, very large passenger jet". He watched "it just plow right into the side of the Pentagon. The nose penetrated into the portico. And then it sort of disappeared, and there was fire and smoke everywhere." Tim Timmerman, who is a pilot himself, noticed American Airlines markings on the aircraft as he saw it hit the Pentagon. Other drivers on Washington Boulevard, Interstate 395, and Columbia Pike witnessed the crash, as did people in Pentagon City, Crystal City, and other nearby locations. + +Rescue and recovery + +Rescue efforts began immediately after the crash. Almost all the successful rescues of survivors occurred within half an hour of the impact. Initially, rescue efforts were led by the military and civilian employees within the building. Within minutes, the first fire companies arrived and found these volunteers searching near the impact site. The firemen ordered them to leave as they were not properly equipped or trained to deal with the hazards. + +The Arlington County Fire Department (ACFD) assumed command of the immediate rescue operation within ten minutes of the crash. ACFD Assistant Chief James Schwartz implemented an incident command system (ICS) to coordinate response efforts among multiple agencies. It took about an hour for the ICS structure to become fully operational. Firefighters from Fort Myer and Reagan National Airport arrived within minutes. Rescue and firefighting efforts were impeded by rumors of additional incoming planes. Chief Schwartz ordered two evacuations during the day in response to these rumors. + +As firefighters attempted to extinguish the fires, they watched the building in fear of a structural collapse. One firefighter remarked that they "pretty much knew the building was going to collapse because it started making weird sounds and creaking." Officials saw a cornice of the building move and ordered an evacuation. Minutes later, at 10:10, the upper floors of the damaged area of the Pentagon collapsed. The collapsed area was about at its widest point and at its deepest. The amount of time between impact and collapse allowed everyone on the fourth and fifth levels to evacuate safely before the structure collapsed. After 11:00, firefighters mounted a two-pronged attack against the fires. Officials estimated temperatures of up to . While progress was made against the interior fires by late afternoon, firefighters realized a flammable layer of wood under the Pentagon's slate roof had caught fire and begun to spread. Typical firefighting tactics were rendered useless by the reinforced structure as firefighters were unable to reach the fire to extinguish it. Firefighters instead made firebreaks in the roof on September 12 to prevent further spreading. At 18:00 on the 12th, Arlington County issued a press release stating the fire was "controlled" but not fully "extinguished". Firefighters continued to put out smaller fires that ignited in the succeeding days. + +Various pieces of aircraft debris were found within the wreckage at the Pentagon. While on fire and escaping from the Navy Command Center, Lt. Kevin Shaeffer observed a chunk of the aircraft's nose cone and the nose landing gear in the service road between rings B and C. Early in the morning on Friday, September 14, Fairfax County Urban Search and Rescue Team members Carlton Burkhammer and Brian Moravitz came across an "intact seat from the plane's cockpit", while paramedics and firefighters located the two black boxes near the punch out hole in the A–E drive, nearly into the building. The cockpit voice recorder was too badly damaged and charred to retrieve any information, though the flight data recorder yielded useful information. Investigators also found a part of Nawaf al-Hazmi's driver's license in the North Parking Lot rubble pile. Personal effects belonging to victims were found and taken to Fort Myer. + +Remains + +Army engineers determined by 17:30 on the first day that no survivors remained in the damaged section of the building. In the days after the crash, news reports emerged that up to 800 people had died. Army soldiers from Fort Belvoir were the first teams to survey the interior of the crash site and noted the presence of human remains. Federal Emergency Management Agency (FEMA) Urban Search and Rescue teams, including Fairfax County Urban Search and Rescue assisted the search for remains, working through the National Interagency Incident Management System (NIIMS). Kevin Rimrodt, a Navy photographer surveying the Navy Command Center after the attacks, remarked that "there were so many bodies, I'd almost step on them. So I'd have to really take care to look backwards as I'm backing up in the dark, looking with a flashlight, making sure I'm not stepping on somebody." Debris from the Pentagon was taken to the Pentagon's north parking lot for more detailed search for remains and evidence. + +Remains recovered from the Pentagon were photographed, and turned over to the Armed Forces Medical Examiner office, located at Dover Air Force Base in Delaware. The medical examiner's office was able to identify remains belonging to 179 of the victims. Investigators eventually identified 184 of the 189 people who died in the attack. The remains of the five hijackers were identified through a process of elimination, and were turned over as evidence to the Federal Bureau of Investigation (FBI). On September 21, the ACFD relinquished control of the crime scene to the FBI. The Washington Field Office, National Capital Response Squad (NCRS), and the Joint Terrorism Task Force (JTTF) led the crime scene investigation at the Pentagon. + +By October 2, 2001, the search for evidence and remains was complete and the site was turned over to Pentagon officials. In 2002, the remains of 25 victims were buried collectively at Arlington National Cemetery, with a five-sided granite marker inscribed with the names of all the victims in the Pentagon. The ceremony also honored the five victims whose remains were never found. + +Flight recorders + +About 03:40 on September 14, a paramedic and a firefighter who were searching through the debris of the impact site found two dark boxes, about long. They called for an FBI agent, who in turn called for someone from the National Transportation Safety Board (NTSB). The NTSB employee confirmed that these were the flight recorders ("black boxes") from American Airlines Flight77. Dick Bridges, deputy manager for Arlington County, Virginia, said the cockpit voice recorder was damaged on the outside and the flight data recorder was charred. Bridges said the recorders were found "right where the plane came into the building". + +The cockpit voice recorder was transported to the NTSB lab in Washington, D.C., to see what data was salvageable. In its report, the NTSB identified the unit as an L-3 Communications, Fairchild Aviation Recorders model A-100A cockpit voice recordera device which records on magnetic tape. No usable segments of tape were found inside the recorder; according to the NTSB's report, "[t]he majority of the recording tape was fused into a solid block of charred plastic". On the other hand, all the data from the flight data recorder, which used a solid-state drive, was recovered. + +Continuity of operations + +At the moment of impact, Secretary of Defense Donald Rumsfeld was in his office on the other side of the Pentagon, away from the crash site. He ran to the site and assisted the injured. Rumsfeld returned to his office, and went to a conference room in the Executive Support Center where he joined a secure videoteleconference with Vice President Dick Cheney and other officials. On the day of the attacks, DoD officials considered moving their command operations to Site R, a backup facility in Pennsylvania. Secretary of Defense Rumsfeld insisted he remain at the Pentagon, and sent Deputy Secretary Paul Wolfowitz to Site R. The National Military Command Center (NMCC) continued to operate at the Pentagon, even as smoke entered the facility. Engineers and building managers manipulated the ventilation and other building systems that still functioned to draw smoke out of the NMCC and bring in fresh air. + +During a press conference held inside the Pentagon at 18:42, Rumsfeld announced, "The Pentagon's functioning. It will be in business tomorrow." Pentagon employees returned the next day to offices in mostly unaffected areas of the building. By the end of September, more workers returned to the lightly damaged areas of the Pentagon. + +Aftermath + +Early estimates on rebuilding the damaged section of the Pentagon were that it would take three years to complete. However, the project moved forward at an accelerated pace and was completed by the first anniversary of the attack. The rebuilt section of the Pentagon includes a small indoor memorial and chapel at the point of impact. An outdoor memorial, commissioned by the Pentagon and designed by Julie Beckman and Keith Kaseman, was completed on schedule for its dedication on September 11, 2008. Since September 11, American Airlines continued to fly from Dulles International Airport to Los Angeles International Airport until 2020, when flights were permanently suspended. As of 2022, American Airlines operates the flight from Washington to LAX from Ronald Reagan Washington National Airport as Flight 1275 departing at 08:55 using an Airbus A321neo. + +Security camera videos + +The Department of Defense released filmed footage on May 16, 2006, that was recorded by a security camera of American Airlines Flight77 crashing into the Pentagon, with a plane visible in one frame, as a "thin white blur" and an explosion following. The images were made public in response to a December 2004 Freedom of Information Act request by Judicial Watch. Some still images from the video had previously been released and publicly circulated, but this was the first official release of the edited video of the crash. + +A nearby Citgo service station also had security cameras, but a video released on September 15, 2006, did not show the crash because the camera was pointed away from the crash site. + +The Doubletree Hotel, located nearby neighborhood of Crystal City, also had a security camera video. The FBI released the video on December 4, 2006, in response to a FOIA lawsuit filed by Scott Bingham. The footage is "grainy and the focus is soft, but a rapidly growing tower of smoke is visible in the distance on the upper edge of the frame as the plane crashes into the building." + +Memorials + +On September 12, 2002, Defense Secretary Donald Rumsfeld and General Richard Myers, Chairman of the Joint Chiefs of Staff, dedicated the Victims of Terrorist Attack on the Pentagon Memorial at Arlington National Cemetery. The memorial specifically honors the five individuals for whom no identifiable remains were found. This included Dana Falkenberg, age three, who was aboard American Airlines Flight77 with her parents and older sister. A portion of the remains of 25 other victims are also buried at the site. The memorial is a pentagonal granite marker high. On five sides of the memorial along the top are inscribed the words "Victims of Terrorist Attack on the Pentagon September 11, 2001". Aluminum plaques, painted black, are inscribed with the names of the 184 victims of the terrorist attack. The site is located in Section 64, on a slight rise, which gives it a view of the Pentagon. + +At the National September 11 Memorial, the names of the Pentagon victims are inscribed on six panels at the South Pool. + +The Pentagon Memorial, located just southwest of The Pentagon in Arlington County, Virginia, is a permanent outdoor memorial to the 184 people who died as victims in the building and on American Airlines Flight77 during the September11 attacks. Designed by Julie Beckman and Keith Kaseman of the architectural firm of Kaseman Beckman Advanced Strategies with engineers Buro Happold, the memorial opened on September 11, 2008, seven years after the attack. + +Nationalities of victims on the aircraft + +The 53 passengers (excluding the hijackers) and six crew were from: + +See also + American Airlines Flight 11 + United Airlines Flight 93 + United Airlines Flight 175 + List of aircraft hijackings + +References + +Works cited + +External links + + Picture of Aircraft Pre 9-11 + Arlington County After-Action Report, July 23, 2002 + (September 11, 2001) + (September 12, 2001) + + +2001 fires in the United States +2001 in Virginia +2001 murders in the United States +Accidents and incidents involving the Boeing 757 +Aircraft hijackings in the United States +Airliner accidents and incidents caused by hijacking +Airliner accidents and incidents in Virginia +Airliner accidents and incidents involving deliberate crashes +Airliners involved in the September 11 attacks +77 +Articles containing video clips +Attacks on military installations in the 2000s +Attacks in the United States in 2001 +Attacks on government buildings and structures +Aviation accidents and incidents in the United States in 2001 +Dulles International Airport +Filmed murder–suicides +Islamic terrorism in the United States +Mass murder in 2001 +Mass murder in Virginia +Mass murder in the United States +Murder–suicides in Virginia +Murder–suicides in the United States +September 2001 crimes in the United States +Suicides in Virginia +Terrorist incidents in the United States in 2001 +The Pentagon +An ambush is a surprise attack by people lying in wait in a concealed position. Ambushes have been used consistently throughout history, from ancient to modern warfare. In the 20th century, an ambush might involve thousands of soldiers on a large scale, such as over a choke point such as a mountain pass, or a small irregulars band or insurgent group attacking a regular armed force patrols. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack. Sometimes an ambush can involve the exclusive or combined use of improvised explosive devices, that allow the attackers to hit enemy convoys or patrols while minimizing the risk of being exposed to return fire. + +History +This use by early people of ambushing may date as far back as two million years when anthropologists have recently suggested that ambush techniques were used to hunt large game. + +One example from ancient times is the Battle of the Trebia river. Hannibal encamped within striking distance of the Romans with the Trebia River between them, and placed a strong force of cavalry and infantry in concealment, near the battle zone. He had noticed, says Polybius, a "place between the two camps, flat indeed and treeless, but well adapted for an ambuscade, as it was traversed by a water-course with steep banks, densely overgrown with brambles and other thorny plants, and here he proposed to lay a stratagem to surprise the enemy". When the Roman infantry became entangled in combat with his army, the hidden ambush force attacked the Roman infantry in the rear. The result was slaughter and defeat for the Romans. Nevertheless, the battle also displays the effects of good tactical discipline on the part of the ambushed force. Although most of the legions were lost, about 10,000 Romans cut their way through to safety, maintaining unit cohesion. This ability to maintain discipline and break out or maneuver away from a kill zone is a hallmark of good troops and training in any ambush situation. + +Ambushes were widely utilized by the Lusitanians, in particular by their chieftain Viriathus. Their usual tactic, called concursare, involved repeatedly charging and retreating, forcing the enemy to eventually give them chase, in order to set up ambushes in difficult terrain where allied forces would be awaiting. In his first victory, he eluded the siege of Roman praetor Gaius Vetilius and attracted him to a narrow pass next to the Barbesuda river, where he destroyed his army and killed the praetor. Viriathus's ability to turn chases into ambushes would grant him victories over a number of Roman generals. Another famous Lusitanian ambush was performed by Curius and Apuleius on Roman general Quintus Fabius Maximus Servilianus, who led a numerically superior army complete with war elephants and Numidian cavalry. The ambush allowed Curius and Apuleius to steal Servilianus's loot train, although a tactic error in their retreat led to the Romans retaking the train and putting the Lusitanians to flight. Viriathus later defeated Servilianus with a surprise attack. + +Possibly the most famous ambush in ancient warfare was that sprung by Germanic warchief Arminius against the Romans at Battle of the Teutoburg Forest. This particular ambush was to affect the course of Western history. The Germanic forces demonstrated several principles needed for a successful ambush. They took cover in difficult forested terrain, allowing the warriors time and space to mass without detection. They had the element of surprise, and this was also aided by the defection of Arminius from Roman ranks prior to the battle. They sprang the attack when the Romans were most vulnerable; when they had left their fortified camp, and were on the march in a pounding rainstorm. + +The Germans did not dawdle at the hour of decision but attacked quickly, using a massive series of short, rapid, vicious charges against the length of the whole Roman line, with charging units sometimes withdrawing to the forest to regroup while others took their place. The Germans also used blocking obstacles, erecting a trench and earthen wall to hinder Roman movement along the route of the killing zone. The result was mass slaughter of the Romans, and the destruction of three legions. The Germanic victory caused a limit on Roman expansion in the West. Ultimately, it established the Rhine as the boundary of the Roman Empire for the next four hundred years, until the decline of the Roman influence in the West. The Roman Empire made no further concerted attempts to conquer Germania beyond the Rhine. + +There are many notable examples of ambushes during the Roman-Persian Wars. A year after their victory at Carrhae, the Parthians invaded Syria but were driven back after a Roman ambush near Antigonia. Roman Emperor Julian was mortally wounded in an ambush near Samarra in 363 during the retreat from his Persian campaign. A Byzantine invasion of Persian Armenia was repelled by a small force at Anglon who performed a meticulous ambush by using the rough terrain as force multiplier and concealing in houses. Heraclius' discovery of a planned ambush by Shahrbaraz in 622 was a decisive factor in his campaign. + +Arabia during Muhammad's era + +According to Muslim tradition, Islamic Prophet Muhammad used ambush tactics in his military campaigns. His first such use was during the Caravan raids. In the Kharrar caravan raid, Sa`d ibn Abi Waqqas was ordered to lead a raid against the Quraysh. His group consisted of about twenty Muhajirs. This raid was about a month after the previous one. Sa'd, with his soldiers, set up an ambush in the valley of Kharrar on the road to Mecca and waited to raid a Meccan caravan returning from Syria. However, the caravan had already passed and the Muslims returned to Medina without any loot. + +Arab tribes during Muhammad's era also used ambush tactics. One example retold in Muslim tradition is said to have taken place during the First Raid on Banu Thalabah. The Banu Thalabah tribe were already aware of the impending attack; so they lay in wait for the Muslims, and when Muhammad ibn Maslama arrived at the site, the Banu Thalabah with 100 men ambushed the Muslims while they were making preparation to sleep and, after a brief resistance, killed them all except for Muhammad ibn Maslama, who feigned death. A Muslim who happened to pass that way found him and assisted him to return to Medina. The raid was unsuccessful. + +Procedure +In modern warfare, an ambush is most often employed by ground troops up to platoon size against enemy targets, which may be other ground troops, or possibly vehicles. However, in some situations, especially when deep behind enemy lines, the actual attack will be carried out by a platoon, a company-sized unit will be deployed to support the attack group, setting up and maintaining a forward patrol harbour from which the attacking force will deploy, and to which they will retire after the attack. + +Planning + +Ambushes are complex multi-phase operations and are therefore usually planned in some detail. First, a suitable killing zone is identified. This is the place where the ambush will be laid. It is generally a place where enemy units are expected to pass, and which gives reasonable cover for the deployment, execution and extraction phases of the ambush patrol. A path along a wooded valley floor would be a typical example. + +Ambush can be described geometrically as: + Linear, when a number of firing units are equally distant from the linear kill zone. + L-shaped, when a short leg of firing units are placed to enfilade (fire the length of) the sides of the linear kill zone. + V-shaped, when the firing units are distant from the kill zone at the end where the enemy enters, so the firing units lay down bands of intersecting and interlocking fire. This ambush is normally triggered only when the enemy is well into the kill zone. The intersecting bands of fire prevent any attempt of moving out of the kill zone. + +Viet Cong ambush techniques + +Ambush criteria: The terrain for the ambush had to meet strict criteria: + provide concealment to prevent detection from the ground or air + enable ambush force to deploy, encircle and divide the enemy + allow for heavy weapons emplacements to provide sustained fire + enable the ambush force to set up observation posts for early detection of the enemy + permit the secret movement of troops to the ambush position and the dispersal of troops during withdrawal + +One important feature of the ambush was that the target units should 'pile up' after being attacked, thus preventing them any easy means of withdrawal from the kill zone and hindering their use of heavy weapons and supporting fire. Terrain was usually selected which would facilitate this and slow down the enemy. Any terrain around the ambush site which was not favorable to the ambushing force, or which offered some protection to the target, was heavily mined and booby trapped or pre-registered for mortars. + +Ambush units: The NVA/VC ambush formations consisted of: + lead-blocking element + main-assault element + rear-blocking element + observation posts + command post + +Other elements might also be included if the situation demanded, such as a sniper screen along a nearby avenue of approach to delay enemy reinforcements. + +Command posts: When deploying into an ambush site, the NVA first occupied several observation posts, placed to detect the enemy as early as possible and to report on the formation it was using, its strength and firepower, as well as to provide early warning to the unit commander. Usually one main OP and several secondary OPs were established. Runners and occasionally radios were used to communicate between the OPs and the main command post. The OPs were located so that they could observe enemy movement into the ambush and often they would remain in position throughout the ambush in order to report routes of reinforcement and withdrawal by the enemy as well as his maneuver options. Frequently the OPs were reinforced to squad size and served as flank security. The command post was situated in a central location, often on terrain which afforded it a vantage point overlooking the ambush site. + +Recon methods: Reconnaissance elements observing a potential ambush target on the move generally stayed 300–500 meters away. Sometimes a "leapfrogging" recon technique was used. Surveillance units were echeloned one behind the other. As the enemy drew close to the first, it fell back behind the last recon team, leaving an advance group in its place. This one in turn fell back as the enemy again closed the gap, and the cycle rotated. This method helped keep the enemy under continuous observation from a variety of vantage points, and allowed the recon groups to cover one another. + +See also + Ambush predator + Viet Cong and PAVN battle tactics + Flanking maneuver + Flypaper theory (strategy) + List of military tactics + Sniper + +References + +Extract from Lt Col Anthony B.

Abzymes are usually raised in lab animals immunized against synthetic haptens, but some natural abzymes can be found in normal humans (anti-vasoactive intestinal peptide autoantibodies) and in patients with autoimmune diseases such as systemic lupus erythematosus, where they can bind to and hydrolyze DNA. To date abzymes display only weak, modest catalytic activity and have not proved to be of any practical use. They are, however, subjects of considerable academic interest. Studying them has yielded important insights into reaction mechanisms, enzyme structure and function, catalysis, and the immune system itself. + +Enzymes function by lowering the activation energy of the transition state of a chemical reaction, thereby enabling the formation of an otherwise less-favorable molecular intermediate between the reactant(s) and the product(s). If an antibody is developed to bind to a molecule that is structurally and electronically similar to the transition state of a given chemical reaction, the developed antibody will bind to, and stabilize, the transition state, just like a natural enzyme, lowering the activation energy of the reaction, and thus catalyzing the reaction. By raising an antibody to bind to a stable transition-state analog, a new and unique type of enzyme is produced. + +So far, all catalytic antibodies produced have displayed only modest, weak catalytic activity. The reasons for low catalytic activity for these molecules have been widely discussed. Possibilities indicate that factors beyond the binding site may play an important role, in particular through protein dynamics. Some abzymes have been engineered to use metal ions and other cofactors to improve their catalytic activity. + +History + +The possibility of catalyzing a reaction by means of an antibody which binds the transition state was first suggested by William P. Jencks in 1969. In 1994 Peter G. Schultz and Richard A. Lerner received the prestigious Wolf Prize in Chemistry for developing catalytic antibodies for many reactions and popularizing their study into a significant sub-field of enzymology. + +Abzymes in Human healthy Breast Milk +There are a broad range of abzymes in healthy human mothers with DNAse, RNAse, and protease activity. + +Potential HIV treatment + +In a June 2008 issue of the journal Autoimmunity Review, researchers S. Planque, Sudhir Paul, Ph.D, and Yasuhiro Nishiyama, Ph.D of the University Of Texas Medical School at Houston announced that they have engineered an abzyme that degrades the superantigenic region of the gp120 CD4 binding site. This is the one part of the HIV virus outer coating that does not change, because it is the attachment point to T lymphocytes, the key cell in cell-mediated immunity. Once infected by HIV, patients produce antibodies to the more changeable parts of the viral coat. The antibodies are ineffective because of the virus' ability to change their coats rapidly. Because this protein gp120 is necessary for HIV to attach, it does not change across different strains and is a point of vulnerability across the entire range of the HIV variant population. + +The abzyme does more than bind to the site: it catalytically destroys the site, rendering the virus inert, and then can attack other HIV viruses. A single abzyme molecule can destroy thousands of HIV viruses. + +References + +Monoclonal antibodies +Immune system +Enzymes +In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits. The prototypical example of adaptive radiation is finch speciation on the Galapagos ("Darwin's finches"), but examples are known from around the world. + +Characteristics +Four features can be used to identify an adaptive radiation: + +A common ancestry of component species: specifically a recent ancestry. Note that this is not the same as a monophyly in which all descendants of a common ancestor are included. +A phenotype-environment correlation: a significant association between environments and the morphological and physiological traits used to exploit those environments. +Trait utility: the performance or fitness advantages of trait values in their corresponding environments. +Rapid speciation: presence of one or more bursts in the emergence of new species around the time that ecological and phenotypic divergence is underway. + +Conditions +Adaptive radiations are thought to be triggered by an ecological opportunity or a new adaptive zone. Sources of ecological opportunity can be the loss of antagonists (competitors or predators), the evolution of a key innovation or dispersal to a new environment. Any one of these ecological opportunities has the potential to result in an increase in population size and relaxed stabilizing (constraining) selection. As genetic diversity is positively correlated with population size the expanded population will have more genetic diversity compared to the ancestral population. With reduced stabilizing selection phenotypic diversity can also increase. In addition, intraspecific competition will increase, promoting divergent selection to use a wider range of resources. This ecological release provides the potential for ecological speciation and thus adaptive radiation. + +Occupying a new environment might take place under the following conditions: + +A new habitat has opened up: a volcano, for example, can create new ground in the middle of the ocean. This is the case in places like Hawaii and the Galapagos. For aquatic species, the formation of a large new lake habitat could serve the same purpose; the tectonic movement that formed the East African Rift, ultimately leading to the creation of the Rift Valley Lakes, is an example of this. An extinction event could effectively achieve this same result, opening up niches that were previously occupied by species that no longer exist. +This new habitat is relatively isolated. When a volcano erupts on the mainland and destroys an adjacent forest, it is likely that the terrestrial plant and animal species that used to live in the destroyed region will recolonize without evolving greatly. However, if a newly formed habitat is isolated, the species that colonize it will likely be somewhat random and uncommon arrivals. +The new habitat has a wide availability of niche space. The rare colonist can only adaptively radiate into as many forms as there are niches. + +Relationship between mass-extinctions and mass adaptive radiations + +A 2020 study found there to be no direct causal relationship between the proportionally most comparable mass radiations and extinctions in terms of "co-occurrence of species", substantially challenging the hypothesis of "creative mass extinctions". + +Examples + +Darwin's finches +Darwin's finches are an often-used textbook example of adaptive radiation. Today represented by approximately 15 species, Darwin's finches are Galapagos endemics famously adapted for a specialized feeding behavior (although one species, the Cocos finch (Pinaroloxias inornata), is not found in the Galapagos but on the island of Cocos south of Costa Rica). Darwin's finches are not actually finches in the true sense, but are members of the tanager family Thraupidae, and are derived from a single ancestor that arrived in the Galapagos from mainland South America perhaps just 3 million years ago. Excluding the Cocos finch, each species of Darwin's finch is generally widely distributed in the Galapagos and fills the same niche on each island. For the ground finches, this niche is a diet of seeds, and they have thick bills to facilitate the consumption of these hard materials. The ground finches are further specialized to eat seeds of a particular size: the large ground finch (Geospiza magnirostris) is the largest species of Darwin's finch and has the thickest beak for breaking open the toughest seeds, the small ground finch (Geospiza fuliginosa) has a smaller beak for eating smaller seeds, and the medium ground finch (Geospiza fortis) has a beak of intermediate size for optimal consumption of intermediately sized seeds (relative to G. magnirostris and G. fuliginosa). There is some overlap: for example, the most robust medium ground finches could have beaks larger than those of the smallest large ground finches. Because of this overlap, it can be difficult to tell the species apart by eye, though their songs differ. These three species often occur sympatrically, and during the rainy season in the Galapagos when food is plentiful, they specialize little and eat the same, easily accessible foods. It was not well-understood why their beaks were so adapted until Peter and Rosemary Grant studied their feeding behavior in the long dry season, and discovered that when food is scarce, the ground finches use their specialized beaks to eat the seeds that they are best suited to eat and thus avoid starvation. + +The other finches in the Galapagos are similarly uniquely adapted for their particular niche. The cactus finches (Geospiza sp.) have somewhat longer beaks than the ground finches that serve the dual purpose of allowing them to feed on Opuntia cactus nectar and pollen while these plants are flowering, but on seeds during the rest of the year. The warbler-finches (Certhidea sp.) have short, pointed beaks for eating insects. The woodpecker finch (Camarhynchus pallidus) has a slender beak which it uses to pick at wood in search of insects; it also uses small sticks to reach insect prey inside the wood, making it one of the few animals that use tools. + +The mechanism by which the finches initially diversified is still an area of active research. One proposition is that the finches were able to have a non-adaptive, allopatric speciation event on separate islands in the archipelago, such that when they reconverged on some islands, they were able to maintain reproductive isolation. Once they occurred in sympatry, niche specialization was favored so that the different species competed less directly for resources. This second, sympatric event was adaptive radiation. + +Cichlids of the African Great Lakes +The haplochromine cichlid fishes in the Great Lakes of the East African Rift (particularly in Lake Tanganyika, Lake Malawi, and Lake Victoria) form the most speciose modern example of adaptive radiation. These lakes are believed to be home to about 2,000 different species of cichlid, spanning a wide range of ecological roles and morphological characteristics. Cichlids in these lakes fill nearly all of the roles typically filled by many fish families, including those of predators, scavengers, and herbivores, with varying dentitions and head shapes to match their dietary habits. In each case, the radiation events are only a few million years old, making the high level of speciation particularly remarkable. Several factors could be responsible for this diversity: the availability of a multitude of niches probably favored specialization, as few other fish taxa are present in the lakes (meaning that sympatric speciation was the most probable mechanism for initial specialization). Also, continual changes in the water level of the lakes during the Pleistocene (which often turned the largest lakes into several smaller ones) could have created the conditions for secondary allopatric speciation. + +Tanganyika cichlids +Lake Tanganyika is the site from which nearly all the cichlid lineages of East Africa (including both riverine and lake species) originated. Thus, the species in the lake constitute a single adaptive radiation event but do not form a single monophyletic clade. Lake Tanganyika is also the least speciose of the three largest African Great Lakes, with only around 200 species of cichlid; however, these cichlids are more morphologically divergent and ecologically distinct than their counterparts in lakes Malawi and Victoria, an artifact of Lake Tanganyika's older cichlid fauna. Lake Tanganyika itself is believed to have formed 9–12 million years ago, putting a recent cap on the age of the lake's cichlid fauna. Many of Tanganyika's cichlids live very specialized lifestyles. The giant or emperor cichlid (Boulengerochromis microlepis) is a piscivore often ranked the largest of all cichlids (though it competes for this title with South America's Cichla temensis, the speckled peacock bass). It is thought that giant cichlids spawn only a single time, breeding in their third year and defending their young until they reach a large size, before dying of starvation some time thereafter. The three species of Altolamprologus are also piscivores, but with laterally compressed bodies and thick scales enabling them to chase prey into thin cracks in rocks without damaging their skin. Plecodus straeleni has evolved large, strangely curved teeth that are designed to scrape scales off of the sides of other fish, scales being its main source of food. Gnathochromis permaxillaris possesses a large mouth with a protruding upper lip, and feeds by opening this mouth downward onto the sandy lake bottom, sucking in small invertebrates. A number of Tanganyika's cichlids are shell-brooders, meaning that mating pairs lay and fertilize their eggs inside of empty shells on the lake bottom. Lamprologus callipterus is a unique egg-brooding species, with 15 cm-long males amassing collections of shells and guarding them in the hopes of attracting females (about 6 cm in length) to lay eggs in these shells. These dominant males must defend their territories from three types of rival: (1) other dominant males looking to steal shells; (2) younger, "sneaker" males looking to fertilize eggs in a dominant male's territory; and (3) tiny, 2–4 cm "parasitic dwarf" males that also attempt to rush in and fertilize eggs in the dominant male's territory. These parasitic dwarf males never grow to the size of dominant males, and the male offspring of dominant and parasitic dwarf males grow with 100% fidelity into the form of their fathers. A number of other highly specialized Tanganyika cichlids exist aside from these examples, including those adapted for life in open lake water up to 200m deep. + +Malawi cichlids +The cichlids of Lake Malawi constitute a "species flock" of up to 1000 endemic species. Only seven cichlid species in Lake Malawi are not a part of the species flock: the Eastern happy (Astatotilapia calliptera), the sungwa (Serranochromis robustus), and five tilapia species (genera Oreochromis and Coptodon). All of the other cichlid species in the lake are descendants of a single original colonist species, which itself was descended from Tanganyikan ancestors. The common ancestor of Malawi's species flock is believed to have reached the lake 3.4 million years ago at the earliest, making Malawi cichlids' diversification into their present numbers particularly rapid. Malawi's cichlids span a similarly range of feeding behaviors to those of Tanganyika, but also show signs of a much more recent origin. For example, all members of the Malawi species flock are mouth-brooders, meaning the female keeps her eggs in her mouth until they hatch; in almost all species, the eggs are also fertilized in the female's mouth, and in a few species, the females continue to guard their fry in their mouth after they hatch. Males of most species display predominantly blue coloration when mating. However, a number of particularly divergent species are known from Malawi, including the piscivorous Nimbochromis livingtonii, which lies on its side in the substrate until small cichlids, perhaps drawn to its broken white patterning, come to inspect the predator - at which point they are swiftly eaten. + +Victoria cichlids +Lake Victoria's cichlids are also a species flock, once composed of some 500 or more species. The deliberate introduction of the Nile Perch (Lates niloticus) in the 1950s proved disastrous for Victoria cichlids, and the collective biomass of the Victoria cichlid species flock has decreased substantially and an unknown number of species have become extinct. However, the original range of morphological and behavioral diversity seen in the lake's cichlid fauna is still mostly present today, if endangered. These again include cichlids specialized for niches across the trophic spectrum, as in Tanganyika and Malawi, but again, there are standouts. Victoria is famously home to many piscivorous cichlid species, some of which feed by sucking the contents out of mouthbrooding females' mouths. Victoria's cichlids constitute a far younger radiation than even that of Lake Malawi, with estimates of the age of the flock ranging from 200,000 years to as little as 14,000. + +Adaptive radiation in Hawaii +Hawaii has served as the site of a number of adaptive radiation events, owing to its isolation, recent origin, and large land area. The three most famous examples of these radiations are presented below, though insects like the Hawaiian drosophilid flies and Hyposmocoma moths have also undergone adaptive radiation. + +Hawaiian honeycreepers +The Hawaiian honeycreepers form a large, highly morphologically diverse species group of birds that began radiating in the early days of the Hawaiian archipelago. While today only 17 species are known to persist in Hawaii (3 more may or may not be extinct), there were more than 50 species prior to Polynesian colonization of the archipelago (between 18 and 21 species have gone extinct since the discovery of the islands by westerners). The Hawaiian honeycreepers are known for their beaks, which are specialized to satisfy a wide range of dietary needs: for example, the beak of the ʻakiapōlāʻau (Hemignathus wilsoni) is characterized by a short, sharp lower mandible for scraping bark off of trees, and the much longer, curved upper mandible is used to probe the wood underneath for insects. Meanwhile, the ʻiʻiwi (Drepanis coccinea) has a very long curved beak for reaching nectar deep in Lobelia flowers. An entire clade of Hawaiian honeycreepers, the tribe Psittirostrini, is composed of thick-billed, mostly seed-eating birds, like the Laysan finch (Telespiza cantans). In at least some cases, similar morphologies and behaviors appear to have evolved convergently among the Hawaiian honeycreepers; for example, the short, pointed beaks of Loxops and Oreomystis evolved separately despite once forming the justification for lumping the two genera together. The Hawaiian honeycreepers are believed to have descended from a single common ancestor some 15 to 20 million years ago, though estimates range as low as 3.5 million years. + +Hawaiian silverswords + +Adaptive radiation is not a strictly vertebrate phenomenon, and examples are also known from among plants. The most famous example of adaptive radiation in plants is quite possibly the Hawaiian silverswords, named for alpine desert-dwelling Argyroxiphium species with long, silvery leaves that live for up to 20 years before growing a single flowering stalk and then dying. The Hawaiian silversword alliance consists of twenty-eight species of Hawaiian plants which, aside from the namesake silverswords, includes trees, shrubs, vines, cushion plants, and more. The silversword alliance is believed to have originated in Hawaii no more than 6 million years ago, making this one of Hawaii's youngest adaptive radiation events. This means that the silverswords evolved on Hawaii's modern high islands, and descended from a single common ancestor that arrived on Kauai from western North America. The closest modern relatives of the silverswords today are California tarweeds of the family Asteraceae. + +Hawaiian lobelioids +Hawaii is also the site of a separate major floral adaptive radiation event: the Hawaiian lobelioids. The Hawaiian lobelioids are significantly more speciose than the silverswords, perhaps because they have been present in Hawaii for so much longer: they descended from a single common ancestor who arrived in the archipelago up to 15 million years ago. Today the Hawaiian lobelioids form a clade of over 125 species, including succulents, trees, shrubs, epiphytes, etc. Many species have been lost to extinction and many of the surviving species endangered. + +Caribbean anoles +Anole lizards are distributed broadly in the New World, from the Southeastern US to South America. With over 400 species currently recognized, often placed in a single genus (Anolis), they constitute one of the largest radiation events among all lizards. Anole radiation on the mainland has largely been a process of speciation, and is not adaptive to any great degree, but anoles on each of the Greater Antilles (Cuba, Hispaniola, Puerto Rico, and Jamaica) have adaptively radiated in separate, convergent ways. On each of these islands, anoles have evolved with such a consistent set of morphological adaptations that each species can be assigned to one of six "ecomorphs": trunk–ground, trunk–crown, grass–bush, crown–giant, twig, and trunk. Take, for example, crown–giants from each of these islands: the Cuban Anolis luteogularis, Hispaniola's Anolis ricordii, Puerto Rico's Anolis cuvieri, and Jamaica's Anolis garmani (Cuba and Hispaniola are both home to more than one species of crown–giant). These anoles are all large, canopy-dwelling species with large heads and large lamellae (scales on the undersides of the fingers and toes that are important for traction in climbing), and yet none of these species are particularly closely related and appear to have evolved these similar traits independently. The same can be said of the other five ecomorphs across the Caribbean's four largest islands. Much like in the case of the cichlids of the three largest African Great Lakes, each of these islands is home to its own convergent Anolis adaptive radiation event. + +Other examples +Presented above are the most well-documented examples of modern adaptive radiation, but other examples are known. Populations of three-spined sticklebacks have repeatedly diverged and evolved into distinct ecotypes. On Madagascar, birds of the family Vangidae are marked by very distinct beak shapes to suit their ecological roles. Madagascan mantellid frogs have radiated into forms that mirror other tropical frog faunas, with the brightly colored mantellas (Mantella) having evolved convergently with the Neotropical poison dart frogs of Dendrobatidae, while the arboreal Boophis species are the Madagascan equivalent of tree frogs and glass frogs. The pseudoxyrhophiine snakes of Madagascar have evolved into fossorial, arboreal, terrestrial, and semi-aquatic forms that converge with the colubroid faunas in the rest of the world. These Madagascan examples are significantly older than most of the other examples presented here: Madagascar's fauna has been evolving in isolation since the island split from India some 88 million years ago, and the Mantellidae originated around 50 mya. Older examples are known: the K-Pg extinction event, which caused the disappearance of the dinosaurs and most other reptilian megafauna 65 million years ago, is seen as having triggered a global adaptive radiation event that created the mammal diversity that exists today. + +See also + + Cambrian explosion—the most notable evolutionary radiation event + Evolutionary radiation—a more general term to describe any radiation + List of adaptive radiated Hawaiian honeycreepers by form + List of adaptive radiated marsupials by form + Nonadaptive radiation + +References + +Further reading + Wilson, E. et al.

The proteins may be separated by charge and/or size (isoelectric focusing agarose electrophoresis is essentially size independent), and the DNA and RNA fragments by length. Biomolecules are separated by applying an electric field to move the charged molecules through an agarose matrix, and the biomolecules are separated by size in the agarose gel matrix. + +Agarose gel is easy to cast, has relatively fewer charged groups, and is particularly suitable for separating DNA of size range most often encountered in laboratories, which accounts for the popularity of its use. The separated DNA may be viewed with stain, most commonly under UV light, and the DNA fragments can be extracted from the gel with relative ease. Most agarose gels used are between 0.7–2% dissolved in a suitable electrophoresis buffer. + +Properties of agarose gel + +Agarose gel is a three-dimensional matrix formed of helical agarose molecules in supercoiled bundles that are aggregated into three-dimensional structures with channels and pores through which biomolecules can pass. The 3-D structure is held together with hydrogen bonds and can therefore be disrupted by heating back to a liquid state. The melting temperature is different from the gelling temperature, depending on the sources, agarose gel has a gelling temperature of 35–42 °C and a melting temperature of 85–95 °C. Low-melting and low-gelling agaroses made through chemical modifications are also available. + +Agarose gel has large pore size and good gel strength, making it suitable as an anticonvection medium for the electrophoresis of DNA and large protein molecules. The pore size of a 1% gel has been estimated from 100 nm to 200–500 nm, and its gel strength allows gels as dilute as 0.15% to form a slab for gel electrophoresis. Low-concentration gels (0.1–0.2%) however are fragile and therefore hard to handle. Agarose gel has lower resolving power than polyacrylamide gel for DNA but has a greater range of separation, and is therefore used for DNA fragments of usually 50–20,000 bp in size. The limit of resolution for standard agarose gel electrophoresis is around 750 kb, but resolution of over 6 Mb is possible with pulsed field gel electrophoresis (PFGE). It can also be used to separate large proteins, and it is the preferred matrix for the gel electrophoresis of particles with effective radii larger than 5–10 nm. A 0.9% agarose gel has pores large enough for the entry of bacteriophage T4. + +The agarose polymer contains charged groups, in particular pyruvate and sulphate. These negatively charged groups create a flow of water in the opposite direction to the movement of DNA in a process called electroendosmosis (EEO), and can therefore retard the movement of DNA and cause blurring of bands. Higher concentration gels would have higher electroendosmotic flow. Low EEO agarose is therefore generally preferred for use in agarose gel electrophoresis of nucleic acids, but high EEO agarose may be used for other purposes. The lower sulphate content of low EEO agarose, particularly low-melting point (LMP) agarose, is also beneficial in cases where the DNA extracted from gel is to be used for further manipulation as the presence of contaminating sulphates may affect some subsequent procedures, such as ligation and PCR. Zero EEO agaroses however are undesirable for some applications as they may be made by adding positively charged groups and such groups can affect subsequent enzyme reactions. Electroendosmosis is a reason agarose is used in preference to agar as the agaropectin component in agar contains a significant amount of negatively charged sulphate and carboxyl groups. The removal of agaropectin in agarose substantially reduces the EEO, as well as reducing the non-specific adsorption of biomolecules to the gel matrix. However, for some applications such as the electrophoresis of serum proteins, a high EEO may be desirable, and agaropectin may be added in the gel used. + +Migration of nucleic acids in agarose gel + +Factors affecting migration of nucleic acid in gel + +A number of factors can affect the migration of nucleic acids: the dimension of the gel pores (gel concentration), size of DNA being electrophoresed, the voltage used, the ionic strength of the buffer, and the concentration of intercalating dye such as ethidium bromide if used during electrophoresis. + +Smaller molecules travel faster than larger molecules in gel, and double-stranded DNA moves at a rate that is inversely proportional to the logarithm of the number of base pairs. This relationship however breaks down with very large DNA fragments, and separation of very large DNA fragments requires the use of pulsed field gel electrophoresis (PFGE), which applies alternating current from different directions and the large DNA fragments are separated as they reorient themselves with the changing field. + +For standard agarose gel electrophoresis, larger molecules are resolved better using a low concentration gel while smaller molecules separate better at high concentration gel. Higher concentration gels, however, require longer run times (sometimes days). + +The movement of the DNA may be affected by the conformation of the DNA molecule, for example, supercoiled DNA usually moves faster than relaxed DNA because it is tightly coiled and hence more compact. In a normal plasmid DNA preparation, multiple forms of DNA may be present. Gel electrophoresis of the plasmids would normally show the negatively supercoiled form as the main band, while nicked DNA (open circular form) and the relaxed closed circular form appears as minor bands. The rate at which the various forms move however can change using different electrophoresis conditions, and the mobility of larger circular DNA may be more strongly affected than linear DNA by the pore size of the gel. + +Ethidium bromide which intercalates into circular DNA can change the charge, length, as well as the superhelicity of the DNA molecule, therefore its presence in gel during electrophoresis can affect its movement. For example, the positive charge of ethidium bromide can reduce the DNA movement by 15%. Agarose gel electrophoresis can be used to resolve circular DNA with different supercoiling topology. + +DNA damage due to increased cross-linking will also reduce electrophoretic DNA migration in a dose-dependent way. + +The rate of migration of the DNA is proportional to the voltage applied, i.e. the higher the voltage, the faster the DNA moves. The resolution of large DNA fragments however is lower at high voltage. The mobility of DNA may also change in an unsteady field – in a field that is periodically reversed, the mobility of DNA of a particular size may drop significantly at a particular cycling frequency. This phenomenon can result in band inversion in field inversion gel electrophoresis (FIGE), whereby larger DNA fragments move faster than smaller ones. + +Migration anomalies + "Smiley" gels - this edge effect is caused when the voltage applied is too high for the gel concentration used. + Overloading of DNA - overloading of DNA slows down the migration of DNA fragments. + Contamination - presence of impurities, such as salts or proteins can affect the movement of the DNA. + +Mechanism of migration and separation + +The negative charge of its phosphate backbone moves the DNA towards the positively charged anode during electrophoresis. However, the migration of DNA molecules in solution, in the absence of a gel matrix, is independent of molecular weight during electrophoresis. The gel matrix is therefore responsible for the separation of DNA by size during electrophoresis, and a number of models exist to explain the mechanism of separation of biomolecules in gel matrix. A widely accepted one is the Ogston model which treats the polymer matrix as a sieve. A globular protein or a random coil DNA moves through the interconnected pores, and the movement of larger molecules is more likely to be impeded and slowed down by collisions with the gel matrix, and the molecules of different sizes can therefore be separated in this sieving process. + +The Ogston model however breaks down for large molecules whereby the pores are significantly smaller than size of the molecule. For DNA molecules of size greater than 1 kb, a reptation model (or its variants) is most commonly used. This model assumes that the DNA can crawl in a "snake-like" fashion (hence "reptation") through the pores as an elongated molecule. A biased reptation model applies at higher electric field strength, whereby the leading end of the molecule become strongly biased in the forward direction and pulls the rest of the molecule along. Real-time fluorescence microscopy of stained molecules, however, showed more subtle dynamics during electrophoresis, with the DNA showing considerable elasticity as it alternately stretching in the direction of the applied field and then contracting into a ball, or becoming hooked into a U-shape when it gets caught on the polymer fibres. + +General procedure + +The details of an agarose gel electrophoresis experiment may vary depending on methods, but most follow a general procedure. + +Casting of gel + +The gel is prepared by dissolving the agarose powder in an appropriate buffer, such as TAE or TBE, to be used in electrophoresis. The agarose is dispersed in the buffer before heating it to near-boiling point, but avoid boiling. The melted agarose is allowed to cool sufficiently before pouring the solution into a cast as the cast may warp or crack if the agarose solution is too hot. A comb is placed in the cast to create wells for loading sample, and the gel should be completely set before use. + +The concentration of gel affects the resolution of DNA separation. The agarose gel is composed of microscopic pores through which the molecules travel, and there is an inverse relationship between the pore size of the agarose gel and the concentration – pore size decreases as the density of agarose fibers increases. High gel concentration improves separation of smaller DNA molecules, while lowering gel concentration permits large DNA molecules to be separated. The process allows fragments ranging from 50 base pairs to several mega bases to be separated depending on the gel concentration used. The concentration is measured in weight of agarose over volume of buffer used (g/ml). For a standard agarose gel electrophoresis, a 0.8% gel gives good separation or resolution of large 5–10kb DNA fragments, while 2% gel gives good resolution for small 0.2–1kb fragments. 1% gels is often used for a standard electrophoresis. High percentage gels are often brittle and may not set evenly, while low percentage gels (0.1-0.2%) are fragile and not easy to handle. Low-melting-point (LMP) agarose gels are also more fragile than normal agarose gel. Low-melting point agarose may be used on its own or simultaneously with standard agarose for the separation and isolation of DNA. PFGE and FIGE are often done with high percentage agarose gels. + +Loading of samples +Once the gel has set, the comb is removed, leaving wells where DNA samples can be loaded. Loading buffer is mixed with the DNA sample before the mixture is loaded into the wells. The loading buffer contains a dense compound, which may be glycerol, sucrose, or Ficoll, that raises the density of the sample so that the DNA sample may sink to the bottom of the well. If the DNA sample contains residual ethanol after its preparation, it may float out of the well. The loading buffer also includes colored dyes such as xylene cyanol and bromophenol blue used to monitor the progress of the electrophoresis. The DNA samples are loaded using a pipette. + +Electrophoresis + +Agarose gel electrophoresis is most commonly done horizontally in a subaquaeous mode whereby the slab gel is completely submerged in buffer during electrophoresis. It is also possible, but less common, to perform the electrophoresis vertically, as well as horizontally with the gel raised on agarose legs using an appropriate apparatus. The buffer used in the gel is the same as the running buffer in the electrophoresis tank, which is why electrophoresis in the subaquaeous mode is possible with agarose gel. + +For optimal resolution of DNA greater than 2kb in size in standard gel electrophoresis, 5 to 8 V/cm is recommended (the distance in cm refers to the distance between electrodes, therefore this recommended voltage would be 5 to 8 multiplied by the distance between the electrodes in cm). Voltage may also be limited by the fact that it heats the gel and may cause the gel to melt if it is run at high voltage for a prolonged period, especially if the gel used is LMP agarose gel. Too high a voltage may also reduce resolution, as well as causing band streaking for large DNA molecules. Too low a voltage may lead to broadening of band for small DNA fragments due to dispersion and diffusion. + +Since DNA is not visible in natural light, the progress of the electrophoresis is monitored using colored dyes. Xylene cyanol (light blue color) comigrates large DNA fragments, while Bromophenol blue (dark blue) comigrates with the smaller fragments. Less commonly used dyes include Cresol Red and Orange G which migrate ahead of bromophenol blue. A DNA marker is also run together for the estimation of the molecular weight of the DNA fragments. Note however that the size of a circular DNA like plasmids cannot be accurately gauged using standard markers unless it has been linearized by restriction digest, alternatively a supercoiled DNA marker may be used. + +Staining and visualization + +DNA as well as RNA are normally visualized by staining with ethidium bromide, which intercalates into the major grooves of the DNA and fluoresces under UV light. The intercalation depends on the concentration of DNA and thus, a band with high intensity will indicate a higher amount of DNA compared to a band of less intensity. The ethidium bromide may be added to the agarose solution before it gels, or the DNA gel may be stained later after electrophoresis. Destaining of the gel is not necessary but may produce better images. Other methods of staining are available; examples are MIDORI Green, SYBR Green, GelRed, methylene blue, brilliant cresyl blue, Nile blue sulphate, and crystal violet. SYBR Green, GelRed and other similar commercial products are sold as safer alternatives to ethidium bromide as it has been shown to be mutagenic in Ames test, although the carcinogenicity of ethidium bromide has not actually been established. SYBR Green requires the use of a blue-light transilluminator. DNA stained with crystal violet can be viewed under natural light without the use of a UV transilluminator which is an advantage, however it may not produce a strong band. + +When stained with ethidium bromide, the gel is viewed with an ultraviolet (UV) transilluminator. The UV light excites the electrons within the aromatic ring of ethidium bromide, and once they return to the ground state, light is released, making the DNA and ethidium bromide complex fluoresce. Standard transilluminators use wavelengths of 302/312-nm (UV-B), however exposure of DNA to UV radiation for as little as 45 seconds can produce damage to DNA and affect subsequent procedures, for example reducing the efficiency of transformation, in vitro transcription, and PCR. Exposure of DNA to UV radiation therefore should be limited. Using a higher wavelength of 365 nm (UV-A range) causes less damage to the DNA but also produces much weaker fluorescence with ethidium bromide. Where multiple wavelengths can be selected in the transilluminator, shorter wavelength can be used to capture images, while longer wavelength should be used if it is necessary to work on the gel for any extended period of time. + +The transilluminator apparatus may also contain image capture devices, such as a digital or polaroid camera, that allow an image of the gel to be taken or printed. + +For gel electrophoresis of protein, the bands may be visualised with Coomassie or silver stains. + +Downstream procedures +The separated DNA bands are often used for further procedures, and a DNA band may be cut out of the gel as a slice, dissolved and purified. Contaminants however may affect some downstream procedures such as PCR, and low melting point agarose may be preferred in some cases as it contains fewer of the sulphates that can affect some enzymatic reactions. The gels may also be used for blotting techniques. + +Buffers +In general, the ideal buffer should have good conductivity, produce less heat and have a long life. There are a number of buffers used for agarose electrophoresis; common ones for nucleic acids include Tris/Acetate/EDTA (TAE) and Tris/Borate/EDTA (TBE). The buffers used contain EDTA to inactivate many nucleases which require divalent cation for their function. The borate in TBE buffer can be problematic as borate can polymerize, and/or interact with cis diols such as those found in RNA. TAE has the lowest buffering capacity, but it provides the best resolution for larger DNA. This means a lower voltage and more time, but a better product. + +Many other buffers have been proposed, e.g. lithium borate (LB), iso electric histidine, pK matched goods buffers, etc.; in most cases the purported rationale is lower current (less heat) and or matched ion mobilities, which leads to longer buffer life. Tris-phosphate buffer has high buffering capacity but cannot be used if DNA extracted is to be used in phosphate sensitive reaction. LB is relatively new and is ineffective in resolving fragments larger than 5 kbp; However, with its low conductivity, a much higher voltage could be used (up to 35 V/cm), which means a shorter analysis time for routine electrophoresis. As low as one base pair size difference could be resolved in 3% agarose gel with an extremely low conductivity medium (1 mM lithium borate). + +Other buffering system may be used in specific applications, for example, barbituric acid-sodium barbiturate or Tris-barbiturate buffers may be used for in agarose gel electrophoresis of proteins, for example in the detection of abnormal distribution of proteins. + +Applications +Estimation of the size of DNA molecules following digestion with restriction enzymes, e.g., in restriction mapping of cloned DNA. +Estimation of the DNA concentration by comparing the intensity of the nucleic acid band with the corresponding band of the size marker. +Analysis of products of a polymerase chain reaction (PCR), e.g., in molecular genetic diagnosis or genetic fingerprinting +Separation of DNA fragments for extraction and purification. +Separation of restricted genomic DNA prior to Southern transfer, or of RNA prior to Northern transfer. +Separation of proteins, for example, screening of protein abnormalities in clinical chemistry. + +Agarose gels are easily cast and handled compared to other matrices and nucleic acids are not chemically altered during electrophoresis. Samples are also easily recovered. After the experiment is finished, the resulting gel can be stored in a plastic bag in a refrigerator. + +Electrophoresis is performed in buffer solutions to reduce pH changes due to the electric field, which is important because the charge of DNA and RNA depends on pH, but running for too long can exhaust the buffering capacity of the solution. Further, different preparations of genetic material may not migrate consistently with each other, for morphological or other reasons. + +See also +Gel electrophoresis +Immunodiffusion, Immunoelectrophoresis +SDD-AGE +Northern blot +SDS-polyacrylamide gel electrophoresis +Southern blot + +References + +External links +How to run a DNA or RNA gel +Animation of gel analysis of DNA restriction fragments +Video and article of agarose gel electrophoresis +Step by step photos of running a gel and extracting DNA +Drinking straw electrophoresis! +A typical method from wikiversity +Building a gel electrophoresis chamber + +Biological techniques and tools +Molecular biology +Electrophoresis +Polymerase chain reaction +Articles containing video clips +An allele is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution. The word is a short form of "allelomorph". + +"The chromosomal or genomic location of a gene or any other genetic element is called a locus (plural: loci) and alternative DNA sequences at a locus are called alleles." + +The simplest alleles are single nucleotide polymorphisms (SNP), but they can also be insertions and deletions of up to several thousand base pairs. + +Most alleles observed result in little or no change in the function of the gene product it codes for. However, sometimes different alleles can result in different observable phenotypic traits, such as different pigmentation. A notable example of this is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of a single gene with two alleles. + +Nearly all multicellular organisms have two sets of chromosomes at some point in their biological life cycle; that is, they are diploid. In this case, the chromosomes can be paired. Each chromosome in the pair contains the same genes in the same order, and place, along the length of the chromosome. For a given gene, if the two chromosomes contain the same allele, they, and the organism, are homozygous with respect to that gene. If the alleles are different, they, and the organism, are heterozygous with respect to that gene. + +Popular definitions of 'allele' typically refer only to different alleles within genes. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants). In population genetics, nearly every living human's phenotype for the ABO gene is some combination of just these six alleles. + +Etymology +The word "allele" is a short form of allelomorph ("other form", a word coined by British geneticists William Bateson and Edith Rebecca Saunders) in the 1920s, which was used in the early days of genetics to describe variant forms of a gene detected as different phenotypes. It derives from the Greek prefix ἀλληλο-, allelo-, meaning "mutual", "reciprocal", or "each other", which itself is related to the Greek adjective ἄλλος, allos (cognate with Latin alius), meaning "other". + +Alleles that lead to dominant or recessive phenotypes + +In many cases, genotypic interactions between the two alleles at a locus can be described as dominant or recessive, according to which of the two homozygous phenotypes the heterozygote most resembles. Where the heterozygote is indistinguishable from one of the homozygotes, the allele expressed is the one that leads to the "dominant" phenotype, and the other allele is said to be "recessive". The degree and pattern of dominance varies among loci. This type of interaction was first formally-described by Gregor Mendel. However, many traits defy this simple categorization and the phenotypes are modelled by co-dominance and polygenic inheritance. + +The term "wild type" allele is sometimes used to describe an allele that is thought to contribute to the typical phenotypic character as seen in "wild" populations of organisms, such as fruit flies (Drosophila melanogaster). Such a "wild type" allele was historically regarded as leading to a dominant (overpowering – always expressed), common, and normal phenotype, in contrast to "mutant" alleles that lead to recessive, rare, and frequently deleterious phenotypes. It was formerly thought that most individuals were homozygous for the "wild type" allele at most gene loci, and that any alternative "mutant" allele was found in homozygous form in a small minority of "affected" individuals, often as genetic diseases, and more frequently in heterozygous form in "carriers" for the mutant allele. It is now appreciated that most or all gene loci are highly polymorphic, with multiple alleles, whose frequencies vary from population to population, and that a great deal of genetic variation is hidden in the form of alleles that do not produce obvious phenotypic differences. Wild type alleles are often denoted by a superscript plus sign (i.e., p for an allele p). + +Multiple alleles + +A population or species of organisms typically includes multiple alleles at each locus among various individuals. Allelic variation at a locus is measurable as the number of alleles (polymorphism) present, or the proportion of heterozygotes in the population. A null allele is a gene variant that lacks the gene's normal function because it either is not expressed, or the expressed protein is inactive. + +For example, at the gene locus for the ABO blood type carbohydrate antigens in humans, classical genetics recognizes three alleles, IA, IB, and i, which determine compatibility of blood transfusions. Any individual has one of six possible genotypes (IAIA, IAi, IBIB, IBi, IAIB, and ii) which produce one of four possible phenotypes: "Type A" (produced by IAIA homozygous and IAi heterozygous genotypes), "Type B" (produced by IBIB homozygous and IBi heterozygous genotypes), "Type AB" produced by IAIB heterozygous genotype, and "Type O" produced by ii homozygous genotype. (It is now known that each of the A, B, and O alleles is actually a class of multiple alleles with different DNA sequences that produce proteins with identical properties: more than 70 alleles are known at the ABO locus. Hence an individual with "Type A" blood may be an AO heterozygote, an AA homozygote, or an AA heterozygote with two different "A" alleles.) + +Genotype frequencies + +The frequency of alleles in a diploid population can be used to predict the frequencies of the corresponding genotypes (see Hardy–Weinberg principle). For a simple model, with two alleles; + + + + + +where p is the frequency of one allele and q is the frequency of the alternative allele, which necessarily sum to unity. Then, p2 is the fraction of the population homozygous for the first allele, 2pq is the fraction of heterozygotes, and q2 is the fraction homozygous for the alternative allele. If the first allele is dominant to the second then the fraction of the population that will show the dominant phenotype is p2 + 2pq, and the fraction with the recessive phenotype is q2. + +With three alleles: + + and + + + +In the case of multiple alleles at a diploid locus, the number of possible genotypes (G) with a number of alleles (a) is given by the expression: + +Allelic dominance in genetic disorders +A number of genetic disorders are caused when an individual inherits two recessive alleles for a single-gene trait. Recessive genetic disorders include albinism, cystic fibrosis, galactosemia, phenylketonuria (PKU), and Tay–Sachs disease. Other disorders are also due to recessive alleles, but because the gene locus is located on the X chromosome, so that males have only one copy (that is, they are hemizygous), they are more frequent in males than in females. Examples include red–green color blindness and fragile X syndrome. + +Other disorders, such as Huntington's disease, occur when an individual inherits only one dominant allele. + +Epialleles +While heritable traits are typically studied in terms of genetic alleles, epigenetic marks such as DNA methylation can be inherited at specific genomic regions in certain species, a process termed transgenerational epigenetic inheritance. The term epiallele is used to distinguish these heritable marks from traditional alleles, which are defined by nucleotide sequence. A specific class of epiallele, the metastable epialleles, has been discovered in mice and in humans which is characterized by stochastic (probabilistic) establishment of epigenetic state that can be mitotically inherited. + +Idiomorph +The term "idiomorph", from Greek 'morphos' (form) and 'idio' (singular, unique), was introduced in 1990 in place of "allele" to denote sequences at the same locus in different strains that have no sequence similarity and probably do not share a common phylogenetic relationship. It is used mainly in the genetic research of mycology. + +See also + +References and notes + +External links + + ALFRED: The ALlele FREquency Database + +Classical genetics +Genetic genealogy +Ampicillin is an antibiotic belonging to the aminopenicillin class of the penicillin family. The drug is used to prevent and treat a number of bacterial infections, such as respiratory tract infections, urinary tract infections, meningitis, salmonellosis, and endocarditis. It may also be used to prevent group B streptococcal infection in newborns. It is used by mouth, by injection into a muscle, or intravenously. + +Common side effects include rash, nausea, and diarrhea. It should not be used in people who are allergic to penicillin. Serious side effects may include Clostridium difficile colitis or anaphylaxis. While usable in those with kidney problems, the dose may need to be decreased. Its use during pregnancy and breastfeeding appears to be generally safe. + +Ampicillin was discovered in 1958 and came into commercial use in 1961. It is on the World Health Organization's List of Essential Medicines. The World Health Organization classifies ampicillin as critically important for human medicine. It is available as a generic medication. + +Medical uses + +Diseases +Bacterial meningitis; an aminoglycoside can be added to increase efficacy against gram-negative meningitis bacteria +Endocarditis by enterococcal strains (off-label use); often given with an aminoglycoside +Gastrointestinal infections caused by contaminated water or food (for example, by Salmonella) +Genito-urinary tract infections +Healthcare-associated infections that are related to infections from using urinary catheters and that are unresponsive to other medications +Otitis media (middle ear infection) +Prophylaxis (i.e. to prevent infection) in those who previously had rheumatic heart disease or are undergoing dental procedures, vaginal hysterectomies, or C-sections.

It was the first "broad spectrum" penicillin with activity against gram-positive bacteria, including Streptococcus pneumoniae, Streptococcus pyogenes, some isolates of Staphylococcus aureus (but not penicillin-resistant or methicillin-resistant strains), Trueperella, and some Enterococcus. It is one of the few antibiotics that works against multidrug resistant Enterococcus faecalis and E. faecium. Activity against gram-negative bacteria includes Neisseria meningitidis, some Haemophilus influenzae, and some of the Enterobacteriaceae (though most Enterobacteriaceae and Pseudomonas are resistant). Its spectrum of activity is enhanced by co-administration of sulbactam, a drug that inhibits beta lactamase, an enzyme produced by bacteria to inactivate ampicillin and related antibiotics. It is sometimes used in combination with other antibiotics that have different mechanisms of action, like vancomycin, linezolid, daptomycin, and tigecycline. + +Available forms +Ampicillin can be administered by mouth, an intramuscular injection (shot) or by intravenous infusion. The oral form, available as capsules or oral suspensions, is not given as an initial treatment for severe infections, but rather as a follow-up to an IM or IV injection. For IV and IM injections, ampicillin is kept as a powder that must be reconstituted. + +IV injections must be given slowly, as rapid IV injections can lead to convulsive seizures. + +Specific populations +Ampicillin is one of the most used drugs in pregnancy, and has been found to be generally harmless both by the Food and Drug Administration in the U.S. (which classified it as category B) and the Therapeutic Goods Administration in Australia (which classified it as category A). It is the drug of choice for treating Listeria monocytogenes in pregnant women, either alone or combined with an aminoglycoside. Pregnancy increases the clearance of ampicillin by up to 50%, and a higher dose is thus needed to reach therapeutic levels. + +Ampicillin crosses the placenta and remains in the amniotic fluid at 50–100% of the concentration in maternal plasma; this can lead to high concentrations of ampicillin in the newborn. + +While lactating mothers secrete some ampicillin into their breast milk, the amount is minimal. + +In newborns, ampicillin has a longer half-life and lower plasma protein binding. The clearance by the kidneys is lower, as kidney function has not fully developed. + +Contraindications +Ampicillin is contraindicated in those with a hypersensitivity to penicillins, as they can cause fatal anaphylactic reactions. Hypersensitivity reactions can include frequent skin rashes and hives, exfoliative dermatitis, erythema multiforme, and a temporary decrease in both red and white blood cells. + +Ampicillin is not recommended in people with concurrent mononucleosis, as over 40% of patients develop a skin rash. + +Side effects +Ampicillin is comparatively less toxic than other antibiotics, and side effects are more likely in those who are sensitive to penicillins and those with a history of asthma or allergies. In very rare cases, it causes severe side effects such as angioedema, anaphylaxis, and C. difficile infection (that can range from mild diarrhea to serious pseudomembranous colitis). Some develop black "furry" tongue. Serious adverse effects also include seizures and serum sickness. The most common side effects, experienced by about 10% of users are diarrhea and rash. Less common side effects can be nausea, vomiting, itching, and blood dyscrasias. The gastrointestinal effects, such as hairy tongue, nausea, vomiting, diarrhea, and colitis, are more common with the oral form of penicillin. Other conditions may develop up several weeks after treatment. + +Overdose +Ampicillin overdose can cause behavioral changes, confusion, blackouts, and convulsions, as well as neuromuscular hypersensitivity, electrolyte imbalance, and kidney failure. + +Interactions + +Ampicillin reacts with probenecid and methotrexate to decrease renal excretion. Large doses of ampicillin can increase the risk of bleeding with concurrent use of warfarin and other oral anticoagulants, possibly by inhibiting platelet aggregation. Ampicillin has been said to make oral contraceptives less effective, but this has been disputed. It can be made less effective by other antibiotic, such as chloramphenicol, erythromycin, cephalosporins, and tetracyclines. For example, tetracyclines inhibit protein synthesis in bacteria, reducing the target against which ampicillin acts. If given at the same time as aminoglycosides, it can bind to it and inactivate it. When administered separately, aminoglycosides and ampicillin can potentiate each other instead. + +Ampicillin causes skin rashes more often when given with allopurinol. + +Both the live cholera vaccine and live typhoid vaccine can be made ineffective if given with ampicillin. Ampicillin is normally used to treat cholera and typhoid fever, lowering the immunological response that the body has to mount. + +Pharmacology + +Mechanism of action + +Ampicillin is in the penicillin group of beta-lactam antibiotics and is part of the aminopenicillin family. It is roughly equivalent to amoxicillin in terms of activity. Ampicillin is able to penetrate gram-positive and some gram-negative bacteria. It differs from penicillin G, or benzylpenicillin, only by the presence of an amino group. This amino group, present on both ampicillin and amoxicillin, helps these antibiotics pass through the pores of the outer membrane of gram-negative bacteria, such as E. coli, Proteus mirabilis, Salmonella enterica, and Shigella. + +Ampicillin acts as an irreversible inhibitor of the enzyme transpeptidase, which is needed by bacteria to make the cell wall. It inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis; therefore, ampicillin is usually bacteriolytic. + +Pharmacokinetics +Ampicillin is well-absorbed from the GI tract (though food reduces its absorption), and reaches peak concentrations in one to two hours. The bioavailability is around 62% for parenteral routes. Unlike other penicillins, which usually bind 60–90% to plasma proteins, ampicillin binds to only 15–20%. + +Ampicillin is distributed through most tissues, though it is concentrated in the liver and kidneys. It can also be found in the cerebrospinal fluid when the meninges become inflamed (such as, for example, meningitis). Some ampicillin is metabolized by hydrolyzing the beta-lactam ring to penicilloic acid, though most of it is excreted unchanged. In the kidneys, it is filtered out mostly by tubular secretion; some also undergoes glomerular filtration, and the rest is excreted in the feces and bile. + +Hetacillin and pivampicillin are ampicillin esters that have been developed to increase bioavailability. + +History +Ampicillin has been used extensively to treat bacterial infections since 1961. Until the introduction of ampicillin by the British company Beecham, penicillin therapies had only been effective against gram-positive organisms such as staphylococci and streptococci. Ampicillin (originally branded as "Penbritin") also demonstrated activity against gram-negative organisms such as H. influenzae, coliforms, and Proteus spp. + +Cost +Ampicillin is relatively inexpensive.

All classes of microbes can evolve resistance where the drugs are no longer effective. Fungi evolve antifungal resistance. Viruses evolve antiviral resistance. Protozoa evolve antiprotozoal resistance, and bacteria evolve antibiotic resistance. Together all of these come under the umbrella of antimicrobial resistance. Microbes resistant to multiple antimicrobials are called multidrug resistant (MDR) and are sometimes referred to as superbugs. Although antimicrobial resistance is a naturally occurring process, it is often the result of improper usage of the drugs and management of the infections. + +Antibiotic resistance is a major subset of AMR, that applies specifically to bacteria that become resistant to antibiotics. Resistance in bacteria can arise naturally by genetic mutation, or by one species acquiring resistance from another. Resistance can appear spontaneously because of random mutations, but also arises through spreading of resistant genes through horizontal gene transfer. However, extended use of antibiotics appears to encourage selection for mutations which can render antibiotics ineffective. Antifungal resistance is a subset of AMR, that specifically applies to fungi that have become resistant to antifungals. Resistance to antifungals can arise naturally, for example by genetic mutation or through aneuploidy. Extended use of antifungals leads to development of antifungal resistance through various mechanisms. + +Clinical conditions due to infections caused by microbes containing AMR cause millions of deaths each year. In 2019 there were around 1.27 million deaths globally caused by bacterial AMR. Infections caused by resistant microbes are more difficult to treat, requiring higher doses of antimicrobial drugs, more expensive antibiotics, or alternative medications which may prove more toxic. These approaches may also cost more. + +The prevention of antibiotic misuse, which can lead to antibiotic resistance, includes taking antibiotics only when prescribed. Narrow-spectrum antibiotics are preferred over broad-spectrum antibiotics when possible, as effectively and accurately targeting specific organisms is less likely to cause resistance, as well as side effects. For people who take these medications at home, education about proper use is essential. Health care providers can minimize spread of resistant infections by use of proper sanitation and hygiene, including handwashing and disinfecting between patients, and should encourage the same of the patient, visitors, and family members. + +Rising drug resistance is caused mainly by use of antimicrobials in humans and other animals, and spread of resistant strains between the two. Growing resistance has also been linked to releasing inadequately treated effluents from the pharmaceutical industry, especially in countries where bulk drugs are manufactured. Antibiotics increase selective pressure in bacterial populations, killing vulnerable bacteria; this increases the percentage of resistant bacteria which continue growing. Even at very low levels of antibiotic, resistant bacteria can have a growth advantage and grow faster than vulnerable bacteria. Similarly, the use of antifungals in agriculture increases selective pressure in fungal populations which triggers the emergence of antifungal resistance. As resistance to antimicrobials becomes more common there is greater need for alternative treatments. Calls for new antimicrobial therapies have been issued, but there is very little development of new drugs which would lead to an improved research process. + +Antimicrobial resistance is increasing globally due to increased prescription and dispensing of antibiotic drugs in developing countries. Estimates are that 700,000 to several million deaths result per year and continues to pose a major public health threat worldwide. Each year in the United States, at least 2.8 million people become infected with bacteria that are resistant to antibiotics and at least 35,000 people die and US$55 billion is spent on increased health care costs and lost productivity. According to World Health Organization (WHO) estimates, 350 million deaths could be caused by AMR by 2050. By then, the yearly death toll will be 10 million, according to a United Nations report. + +There are public calls for global collective action to address the threat that include proposals for international treaties on antimicrobial resistance. The burden of worldwide antibiotic resistance is not completely identified, but low-and middle- income countries with weaker healthcare systems are more affected, with mortality being the highest in sub-Saharan Africa. During the COVID-19 pandemic, priorities changed with action against antimicrobial resistance slowing due to scientists and governments focusing more on SARS-CoV-2 research. At the same time the threat of AMR has increased during the pandemic. + +Definition + +The WHO defines antimicrobial resistance as a microorganism's resistance to an antimicrobial drug that was once able to treat an infection by that microorganism. A person cannot become resistant to antibiotics. Resistance is a property of the microbe, not a person or other organism infected by a microbe. All types of microbes can develop drug resistance. Thus, there are antibiotic, antifungal, antiviral and antiparasitic resistance. + +Antibiotic resistance is a subset of antimicrobial resistance. This more specific resistance is linked to bacteria and thus broken down into two further subsets, microbiological and clinical. Microbiological resistance is the most common and occurs from genes, mutated or inherited, that allow the bacteria to resist the mechanism to kill the microbe associated with certain antibiotics. Clinical resistance is shown through the failure of many therapeutic techniques where the bacteria that are normally susceptible to a treatment become resistant after surviving the outcome of the treatment. In both cases of acquired resistance, the bacteria can pass the genetic catalyst for resistance through horizontal gene transfer: conjugation, transduction, or transformation. This allows the resistance to spread across the same species of pathogen or even similar bacterial pathogens. + +Overview +WHO report released April 2014 stated, "this serious threat is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country. Antibiotic resistance—when bacteria change so antibiotics no longer work in people who need them to treat infections—is now a major threat to public health." + +Global deaths attributable to AMR numbered 1.27 million in 2019. That year, AMR may have contributed to 5 million deaths and one in five people who died due to AMR were children under five years old. + +In 2018, WHO considered antibiotic resistance to be one of the biggest threats to global health, food security and development. Deaths attributable to AMR vary by area: + +The European Centre for Disease Prevention and Control calculated that in 2015 there were 671,689 infections in the EU and European Economic Area caused by antibiotic-resistant bacteria, resulting in 33,110 deaths. Most were acquired in healthcare settings. In 2019 there were 133,000 deaths caused by AMR. + +Causes +Antimicrobial resistance is mainly caused by the overuse/misuse of antimicrobials. This leads to microbes either evolving a defense against drugs used to treat them, or certain strains of microbes that have a natural resistance to antimicrobials becoming much more prevalent than the ones that are easily defeated with medication. While antimicrobial resistance does occur naturally over time, the use of antimicrobial agents in a variety of settings both within the healthcare industry and outside of has led to antimicrobial resistance becoming increasingly more prevalent. + +Although many microbes develop resistance to antibiotics over time though natural mutation, overprescribing and inappropriate prescription of antibiotics have accelerated the problem. It is possible that as many as 1 in 3 prescriptions written for antibiotics are unnecessary. Every year, approximately 154 million prescriptions for antibiotics are written. Of these, up to 46 million are unnecessary or inappropriate for the condition that the patient has. Microbes may naturally develop resistance through genetic mutations that occur during cell division, and although random mutations are rare, many microbes reproduce frequently and rapidly, increasing the chances of members of the population acquiring a mutation that increases resistance. Many individuals stop taking antibiotics when they begin to feel better. When this occurs, it is possible that the microbes that are less susceptible to treatment still remain in the body. If these microbes are able to continue to reproduce, this can lead to an infection by bacteria that are less susceptible or even resistant to an antibiotic. + +Natural occurrence + +Antimicrobial resistance can evolve naturally due to continued exposure to antimicrobials. Natural selection means that organisms that are able to adapt to their environment, survive, and continue to produce offspring. As a result, the types of microorganisms that are able to survive over time with continued attack by certain antimicrobial agents will naturally become more prevalent in the environment, and those without this resistance will become obsolete. + +Some contemporary antimicrobial resistances have also evolved naturally before the use of antimicrobials of human clinical uses. For instance, methicillin-resistance evolved as a pathogen of hedgehogs, possibly as a co-evolutionary adaptation of the pathogen to hedgehogs that are infected by a dermatophyte that naturally produces antibiotics. Also, many soil fungi and bacteria are natural competitors and the original antibiotic Penicillin discovered by Alexander Fleming rapidly lost clinical effectiveness in treating humans and, furthermore, none of the other natural penicillins (F, K, N, X, O, U1 or U6) are currently in clinical use. + +Antimicrobial resistance can be acquired from other microbes through swapping genes in a process termed horizontal gene transfer. This means that once a gene for resistance to an antibiotic appears in a microbial community, it can then spread to other microbes in the community, potentially moving from a non-disease causing microbe to a disease-causing microbe. This process is heavily driven by the “natural selection” processes that happen during antibiotic use or misuse. + +Over time, most of the strains of bacteria and infections present will be the type resistant to the antimicrobial agent being used to treat them, making this agent now ineffective to defeat most microbes. With the increased use of antimicrobial agents, there is a speeding up of this natural process. + +Self-medication +In 89% of countries, antibiotics can only be prescribed by a doctor and supplied by a pharmacy. Self-medication by consumers is defined as "the taking of medicines on one's own initiative or on another person's suggestion, who is not a certified medical professional", and it has been identified as one of the primary reasons for the evolution of antimicrobial resistance. Self-medication with antibiotics is an unsuitable way of using them but a common practice in resource-constrained countries. The practice exposes individuals to the risk of bacteria that have developed antimicrobial resistance. Many people resort to this out of necessity, when access to a physician is unavailable due to lockdowns and GP surgery closures, or when the patients have a limited amount of time or money to see a prescribing doctor. This increased access makes it extremely easy to obtain antimicrobials and an example is India, where in the state of Punjab 73% of the population resorted to treating their minor health issues and chronic illnesses through self-medication. + +Self-medication is higher outside the hospital environment, and this is linked to higher use of antibiotics, with the majority of antibiotics being used in the community rather than hospitals. The prevalence of self-medication in low- and middle-income countries (LMICs) ranges from 8.1% to very high at 93%. Accessibility, affordability, and conditions of health facilities, as well as the health-seeking behavior, are factors that influence self-medication in low- and middle-income countries (LMICs). Two significant issues with self-medication are the lack of knowledge of the public on, firstly, the dangerous effects of certain antimicrobials (for example ciprofloxacin which can cause tendonitis, tendon rupture and aortic dissection) and, secondly, broad microbial resistance and when to seek medical care if the infection is not clearing. In order to determine the public's knowledge and preconceived notions on antibiotic resistance, a screening of 3,537 articles published in Europe, Asia, and North America was done. Of the 55,225 total people surveyed in the articles, 70% had heard of antibiotic resistance previously, but 88% of those people thought it referred to some type of physical change in the human body. With so many people around the world with the ability to self-medicate using antibiotics, and a vast majority unaware of what antimicrobial resistance is, it makes the increase of antimicrobial resistance and its global negative impact much more likely. + +Clinical misuse + +Clinical misuse by healthcare professionals is another contributor to increased antimicrobial resistance. Studies done in the US show that the indication for treatment of antibiotics, choice of the agent used, and the duration of therapy was incorrect in up to 50% of the cases studied. In 2010 and 2011 about a third of antibiotic prescriptions in outpatient settings in the United States were not necessary. Another study in an intensive care unit in a major hospital in France has shown that 30% to 60% of prescribed antibiotics were unnecessary. These inappropriate uses of antimicrobial agents promote the evolution of antimicrobial resistance by supporting the bacteria in developing genetic alterations that lead to resistance. + +According to research conducted in the USA that aimed to evaluate physicians' attitudes and knowledge on antimicrobial resistance in ambulatory settings, only 63% of those surveyed reported antibiotic resistance as a problem in their local practices, while 23% reported the aggressive prescription of antibiotics as necessary to avoid failing to provide adequate care. This demonstrates how a majority of doctors underestimate the impact that their own prescribing habits have on antimicrobial resistance as a whole. It also confirms that some physicians may be overly cautious and prescribe antibiotics for both medical or legal reasons, even when clinical indications for use of these medications are not always confirmed. This can lead to unnecessary antimicrobial use, a pattern which may have worsened during the COVID-19 pandemic. + +Studies have shown that common misconceptions about the effectiveness and necessity of antibiotics to treat common mild illnesses contribute to their overuse. + +Pandemics, disinfectants and healthcare systems +Increased antibiotic use during the early waves of the COVID-19 pandemic may exacerbate this global health challenge. Moreover, pandemic burdens on some healthcare systems may contribute to antibiotic-resistant infections. On the other hand, "increased hand hygiene, decreased international travel, and decreased elective hospital procedures may have reduced AMR pathogen selection and spread in the short term" during the COVID-19 pandemic. The use of disinfectants such as alcohol-based hand sanitizers, and antiseptic hand wash may also have the potential to increase antimicrobial resistance. Extensive use of disinfectants can lead to mutations that induce antimicrobial resistance. + +Environmental pollution +Untreated effluents from pharmaceutical manufacturing industries, hospitals and clinics, and inappropriate disposal of unused or expired medication can expose microbes in the environment to antibiotics and trigger the evolution of resistance. + +Food production + +Livestock + +The antimicrobial resistance crisis also extends to the food industry, specifically with food producing animals. With an ever-increasing human population, there is constant pressure to intensify productivity in many agricultural sectors, including the production of meat as a source of protein. Antibiotics are fed to livestock to act as growth supplements, and a preventative measure to decrease the likelihood of infections. + +This can result in the transfer of resistant bacterial strains into the food that humans eat, causing potentially fatal transfer of disease. While the practice of using antibiotics as growth promoters does result in better yields and meat products, it is a major issue and needs to be decreased in order to prevent antimicrobial resistance. Though the evidence linking antimicrobial usage in livestock to antimicrobial resistance is limited, the World Health Organization Advisory Group on Integrated Surveillance of Antimicrobial Resistance strongly recommended the reduction of use of medically important antimicrobials in livestock. Additionally, the Advisory Group stated that such antimicrobials should be expressly prohibited for both growth promotion and disease prevention in food producing animals. + +By mapping antimicrobial consumption in livestock globally, it was predicted that in 228 countries there would be a total 67% increase in consumption of antibiotics by livestock by 2030. In some countries such as Brazil, Russia, India, China, and South Africa it is predicted that a 99% increase will occur. Several countries have restricted the use of antibiotics in livestock, including Canada, China, Japan, and the US. These restrictions are sometimes associated with a reduction of the prevalence of antimicrobial resistance in humans. + +Pesticides + +Most pesticides protect crops against insects and plants, but in some cases antimicrobial pesticides are used to protect against various microorganisms such as bacteria, viruses, fungi, algae, and protozoa. The overuse of many pesticides in an effort to have a higher yield of crops has resulted in many of these microbes evolving a tolerance against these antimicrobial agents. Currently there are over 4000 antimicrobial pesticides registered with the US Environmental Protection Agency (EPA) and sold to market, showing the widespread use of these agents. It is estimated that for every single meal a person consumes, 0.3 g of pesticides is used, as 90% of all pesticide use is in agriculture. A majority of these products are used to help defend against the spread of infectious diseases, and hopefully protect public health. But out of the large amount of pesticides used, it is also estimated that less than 0.1% of those antimicrobial agents, actually reach their targets. That leaves over 99% of all pesticides used available to contaminate other resources. In soil, air, and water these antimicrobial agents are able to spread, coming in contact with more microorganisms and leading to these microbes evolving mechanisms to tolerate and further resist pesticides. The use of antifungal azole pesticides that drive environmental azole resistance have been linked to azole resistance cases in the clinical setting. The same issues confront the novel antifungal classes (e.g. orotomides) which are again being used in both the clinic and agriculture. + +Prevention + +There have been increasing public calls for global collective action to address the threat, including a proposal for an international treaty on antimicrobial resistance. Further detail and attention is still needed in order to recognize and measure trends in resistance on the international level; the idea of a global tracking system has been suggested but implementation has yet to occur. A system of this nature would provide insight to areas of high resistance as well as information necessary for evaluating programs, introducing interventions and other changes made to fight or reverse antibiotic resistance. + +Duration of antimicrobials +Delaying or minimizing the use of antibiotics for certain conditions may help safely reduce their use. Antimicrobial treatment duration should be based on the infection and other health problems a person may have. For many infections once a person has improved there is little evidence that stopping treatment causes more resistance. Some, therefore, feel that stopping early may be reasonable in some cases. Other infections, however, do require long courses regardless of whether a person feels better. + +Delaying antibiotics for ailments such as a sore throat and otitis media may have not different in the rate of complications compared with immediate antibiotics, for example. When treating respiratory tract infections, clinical judgement is required as to the appropriate treatment (delayed or immediate antibiotic use). + +Monitoring and mapping +There are multiple national and international monitoring programs for drug-resistant threats, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant S. aureus (VRSA), extended spectrum beta-lactamase (ESBL) producing Enterobacterales, vancomycin-resistant Enterococcus (VRE), and multidrug-resistant Acinetobacter baumannii (MRAB). + +ResistanceOpen is an online global map of antimicrobial resistance developed by HealthMap which displays aggregated data on antimicrobial resistance from publicly available and user submitted data. The website can display data for a radius from a location. Users may submit data from antibiograms for individual hospitals or laboratories. European data is from the EARS-Net (European Antimicrobial Resistance Surveillance Network), part of the ECDC. ResistanceMap is a website by the Center for Disease Dynamics, Economics & Policy and provides data on antimicrobial resistance on a global level. + +By comparison there is a lack of national and international monitoring programs for antifungal resistance. + +Limiting antimicrobial use in humans + +Antimicrobial stewardship programmes appear useful in reducing rates of antimicrobial resistance. The antimicrobial stewardship program will also provide pharmacists with the knowledge to educate patients that antibiotics will not work for a virus for example. + +Excessive antimicrobial use has become one of the top contributors to the evolution of antimicrobial resistance. Since the beginning of the antimicrobial era, antimicrobials have been used to treat a wide range of infectious diseases. Overuse of antimicrobials has become the primary cause of rising levels of antimicrobial resistance. The main problem is that doctors are willing to prescribe antimicrobials to ill-informed individuals who believe that antimicrobials can cure nearly all illnesses, including viral infections like the common cold. In an analysis of drug prescriptions, 36% of individuals with a cold or an upper respiratory infection (both usually viral in origin) were given prescriptions for antibiotics. These prescriptions accomplished nothing other than increasing the risk of further evolution of antibiotic resistant bacteria. Using antimicrobials without prescription is another driving force leading to the overuse of antibiotics to self-treat diseases like the common cold, cough, fever, and dysentery resulting in an epidemic of antibiotic resistance in countries like Bangladesh, risking its spread around the globe. Introducing strict antibiotic stewardship in the outpatient setting to reduce inappropriate prescribing of antibiotics may reduce the emerging bacterial resistance. + +The WHO AWaRe (Access, Watch, Reserve) antibiotic book has been introduced to guide antibiotic choice for the 30 most common infections in adults and children to reduce inappropriate prescribing in primary care and hospitals. Narrow spectrum antibiotics are preferred due to their lower resistance potential and broad-spectrum antibiotics are only recommended for people with more severe symptoms. Some antibiotics are more likely to confer resistance, so are kept as reserve antibiotics in the AWaRe book. + +Various diagnostic strategies have been employed to prevent the overuse of antifungal therapy in the clinic, proving a safe alternative to empirical antifungal therapy, and thus underpinning antifungal stewardship schemes. + +At the hospital level +Antimicrobial stewardship teams in hospitals are encouraging optimal use of antimicrobials. The goals of antimicrobial stewardship are to help practitioners pick the right drug at the right dose and duration of therapy while preventing misuse and minimizing the development of resistance. Stewardship interventions may reduce the length of stay by an average of slightly over 1 day while not increasing the risk of death. + +At the primary care level +Given the volume of care provided in primary care (general practice), recent strategies have focused on reducing unnecessary antimicrobial prescribing in this setting. Simple interventions, such as written information explaining when taking antibiotics is not necessary, for example in common infections of the upper respiratory tract, have been shown to reduce antibiotic prescribing. Various tools are also available to help professionals decide if prescribing antimicrobials is necessary. + +Parental expectations, driven by the worry for their children's health, can influence how often children are prescribed antibiotics. Parents often rely on their clinician for advice and reassurance. However a lack of plain language information and not having adequate time for consultation negatively impacts this relationship. In effect parents often rely on past experiences in their expectations rather than reassurance from the clinician. Adequate time for consultation and plain language information can help parents make informed decisions and avoid unnecessary antibiotic use. + +The prescriber should closely adhere to the five rights of drug administration: the right patient, the right drug, the right dose, the right route, and the right time. Microbiological samples should be taken for culture and sensitivity testing before treatment when indicated and treatment potentially changed based on the susceptibility report. + +Health workers and pharmacists can help tackle antibiotic resistance by: enhancing infection prevention and control; only prescribing and dispensing antibiotics when they are truly needed; prescribing and dispensing the right antibiotic(s) to treat the illness. + +At the individual level +People can help tackle resistance by using antibiotics only when prescribed by a doctor; completing the full prescription, never sharing antibiotics with others or using leftover prescriptions. + +Country examples + The Netherlands has the lowest rate of antibiotic prescribing in the OECD, at a rate of 11.4 defined daily doses (DDD) per 1,000 people per day in 2011. The defined daily dose (DDD) is a statistical measure of drug consumption, defined by the World Health Organization (WHO). + Germany and Sweden also have lower prescribing rates, with Sweden's rate having been declining since 2007. + Greece, France and Belgium have high prescribing rates for antibiotics of more than 28 DDD. + +Water, sanitation, hygiene +Infectious disease control through improved water, sanitation and hygiene (WASH) infrastructure needs to be included in the antimicrobial resistance (AMR) agenda. The "Interagency Coordination Group on Antimicrobial Resistance" stated in 2018 that "the spread of pathogens through unsafe water results in a high burden of gastrointestinal disease, increasing even further the need for antibiotic treatment." This is particularly a problem in developing countries where the spread of infectious diseases caused by inadequate WASH standards is a major driver of antibiotic demand. Growing usage of antibiotics together with persistent infectious disease levels have led to a dangerous cycle in which reliance on antimicrobials increases while the efficacy of drugs diminishes. The proper use of infrastructure for water, sanitation and hygiene (WASH) can result in a 47–72 percent decrease of diarrhea cases treated with antibiotics depending on the type of intervention and its effectiveness. A reduction of the diarrhea disease burden through improved infrastructure would result in large decreases in the number of diarrhea cases treated with antibiotics. This was estimated as ranging from 5 million in Brazil to up to 590 million in India by the year 2030. The strong link between increased consumption and resistance indicates that this will directly mitigate the accelerating spread of AMR. Sanitation and water for all by 2030 is Goal Number 6 of the Sustainable Development Goals. + +An increase in hand washing compliance by hospital staff results in decreased rates of resistant organisms. + +Water supply and sanitation infrastructure in health facilities offer significant co-benefits for combatting AMR, and investment should be increased. There is much room for improvement: WHO and UNICEF estimated in 2015 that globally 38% of health facilities did not have a source of water, nearly 19% had no toilets and 35% had no water and soap or alcohol-based hand rub for handwashing. + +Industrial wastewater treatment +Manufacturers of antimicrobials need to improve the treatment of their wastewater (by using industrial wastewater treatment processes) to reduce the release of residues into the environment. + +Limiting antimicrobial use in animals and farming +It is established that the use of antibiotics in animal husbandry can give rise to AMR resistances in bacteria found in food animals to the antibiotics being administered (through injections or medicated feeds). For this reason only antimicrobials that are deemed "not-clinically relevant" are used in these practices. + +Unlike resistance to antibacterials, antifungal resistance can be driven by arable farming, currently there is no regulation on the use of similar antifungal classes in agriculture and the clinic. + +Recent studies have shown that the prophylactic use of "non-priority" or "non-clinically relevant" antimicrobials in feeds can potentially, under certain conditions, lead to co-selection of environmental AMR bacteria with resistance to medically important antibiotics. The possibility for co-selection of AMR resistances in the food chain pipeline may have far-reaching implications for human health. + +Country examples + +Europe +In 1997, European Union health ministers voted to ban avoparcin and four additional antibiotics used to promote animal growth in 1999. In 2006 a ban on the use of antibiotics in European feed, with the exception of two antibiotics in poultry feeds, became effective. In Scandinavia, there is evidence that the ban has led to a lower prevalence of antibiotic resistance in (nonhazardous) animal bacterial populations. As of 2004, several European countries established a decline of antimicrobial resistance in humans through limiting the use of antimicrobials in agriculture and food industries without jeopardizing animal health or economic cost. + +United States +The United States Department of Agriculture (USDA) and the Food and Drug Administration (FDA) collect data on antibiotic use in humans and in a more limited fashion in animals. The FDA first determined in 1977 that there is evidence of emergence of antibiotic-resistant bacterial strains in livestock. The long-established practice of permitting OTC sales of antibiotics (including penicillin and other drugs) to lay animal owners for administration to their own animals nonetheless continued in all states. +In 2000, the FDA announced their intention to revoke approval of fluoroquinolone use in poultry production because of substantial evidence linking it to the emergence of fluoroquinolone-resistant Campylobacter infections in humans. Legal challenges from the food animal and pharmaceutical industries delayed the final decision to do so until 2006. Fluroquinolones have been banned from extra-label use in food animals in the USA since 2007. However, they remain widely used in companion and exotic animals. + +Global action plans and awareness + +The increasing interconnectedness of the world and the fact that new classes of antibiotics have not been developed and approved for more than 25 years highlight the extent to which antimicrobial resistance is a global health challenge. A global action plan to tackle the growing problem of resistance to antibiotics and other antimicrobial medicines was endorsed at the Sixty-eighth World Health Assembly in May 2015. One of the key objectives of the plan is to improve awareness and understanding of antimicrobial resistance through effective communication, education and training. This global action plan developed by the World Health Organization was created to combat the issue of antimicrobial resistance and was guided by the advice of countries and key stakeholders. The WHO's global action plan is composed of five key objectives that can be targeted through different means, and represents countries coming together to solve a major problem that can have future health consequences. These objectives are as follows: + improve awareness and understanding of antimicrobial resistance through effective communication, education and training. + strengthen the knowledge and evidence base through surveillance and research. + reduce the incidence of infection through effective sanitation, hygiene and infection prevention measures. + optimize the use of antimicrobial medicines in human and animal health. + develop the economic case for sustainable investment that takes account of the needs of all countries and to increase investment in new medicines, diagnostic tools, vaccines and other interventions. + +Steps towards progress + React based in Sweden has produced informative material on AMR for the general public. + Videos are being produced for the general public to generate interest and awareness. + The Irish Department of Health published a National Action Plan on Antimicrobial Resistance in October 2017. The Strategy for the Control of Antimicrobial Resistance in Ireland (SARI), Iaunched in 2001 developed Guidelines for Antimicrobial Stewardship in Hospitals in Ireland in conjunction with the Health Protection Surveillance Centre, these were published in 2009. Following their publication a public information campaign 'Action on Antibiotics' was launched to highlight the need for a change in antibiotic prescribing. Despite this, antibiotic prescribing remains high with variance in adherence to guidelines. + The United Kingdom published a 20-year vision for antimicrobial resistance that sets out the goal of containing and controlling AMR by 2040. The vision is supplemented by a 5-year action plan running from 2019 to 2024, building on the previous action plan (2013-2018). + +Antibiotic Awareness Week +The World Health Organization has promoted the first World Antibiotic Awareness Week running from 16 to 22 November 2015. The aim of the week is to increase global awareness of antibiotic resistance. It also wants to promote the correct usage of antibiotics across all fields in order to prevent further instances of antibiotic resistance. + +World Antibiotic Awareness Week has been held every November since 2015. For 2017, the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO) and the World Organisation for Animal Health (OIE) are together calling for responsible use of antibiotics in humans and animals to reduce the emergence of antibiotic resistance. + +United Nations + +In 2016 the Secretary-General of the United Nations convened the Interagency Coordination Group (IACG) on Antimicrobial Resistance. The IACG worked with international organizations and experts in human, animal, and plant health to create a plan to fight antimicrobial resistance. Their report released in April 2019 highlights the seriousness of antimicrobial resistance and the threat it poses to world health. It suggests five recommendations for member states to follow in order to tackle this increasing threat. The IACG recommendations are as follows: + Accelerate progress in countries + Innovate to secure the future + Collaborate for more effective action + Invest for a sustainable response + Strengthen accountability and global governance + +Mechanisms and organisms + +Bacteria + +The five main mechanisms by which bacteria exhibit resistance to antibiotics are: + Drug inactivation or modification: for example, enzymatic deactivation of penicillin G in some penicillin-resistant bacteria through the production of β-lactamases. Drugs may also be chemically modified through the addition of functional groups by transferase enzymes; for example, acetylation, phosphorylation, or adenylation are common resistance mechanisms to aminoglycosides. Acetylation is the most widely used mechanism and can affect a number of drug classes. + Alteration of target- or binding site: for example, alteration of PBP—the binding target site of penicillins—in MRSA and other penicillin-resistant bacteria. Another protective mechanism found among bacterial species is ribosomal protection proteins. These proteins protect the bacterial cell from antibiotics that target the cell's ribosomes to inhibit protein synthesis. The mechanism involves the binding of the ribosomal protection proteins to the ribosomes of the bacterial cell, which in turn changes its conformational shape. This allows the ribosomes to continue synthesizing proteins essential to the cell while preventing antibiotics from binding to the ribosome to inhibit protein synthesis. + Alteration of metabolic pathway: for example, some sulfonamide-resistant bacteria do not require para-aminobenzoic acid (PABA), an important precursor for the synthesis of folic acid and nucleic acids in bacteria inhibited by sulfonamides, instead, like mammalian cells, they turn to using preformed folic acid. + Reduced drug accumulation: by decreasing drug permeability or increasing active efflux (pumping out) of the drugs across the cell surface These pumps within the cellular membrane of certain bacterial species are used to pump antibiotics out of the cell before they are able to do any damage. They are often activated by a specific substrate associated with an antibiotic, as in fluoroquinolone resistance. + Ribosome splitting and recycling: for example, drug-mediated stalling of the ribosome by lincomycin and erythromycin unstalled by a heat shock protein found in Listeria monocytogenes, which is a homologue of HflX from other bacteria. Liberation of the ribosome from the drug allows further translation and consequent resistance to the drug. + +There are several different types of germs that have developed a resistance over time. + +The six pathogens causing most deaths associated with resistance are Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa. They were responsible for 929,000 deaths attributable to resistance and 3.57 million deaths associated with resistance in 2019. + +Penicillinase-producing Neisseria gonorrhoeae developed a resistance to penicillin in 1976. Another example is Azithromycin-resistant Neisseria gonorrhoeae, which developed a resistance to azithromycin in 2011. + +In gram-negative bacteria, plasmid-mediated resistance genes produce proteins that can bind to DNA gyrase, protecting it from the action of quinolones. Finally, mutations at key sites in DNA gyrase or topoisomerase IV can decrease their binding affinity to quinolones, decreasing the drug's effectiveness. + +Some bacteria are naturally resistant to certain antibiotics; for example, gram-negative bacteria are resistant to most β-lactam antibiotics due to the presence of β-lactamase. Antibiotic resistance can also be acquired as a result of either genetic mutation or horizontal gene transfer. Although mutations are rare, with spontaneous mutations in the pathogen genome occurring at a rate of about 1 in 105 to 1 in 108 per chromosomal replication, the fact that bacteria reproduce at a high rate allows for the effect to be significant. Given that lifespans and production of new generations can be on a timescale of mere hours, a new (de novo) mutation in a parent cell can quickly become an inherited mutation of widespread prevalence, resulting in the microevolution of a fully resistant colony. However, chromosomal mutations also confer a cost of fitness. For example, a ribosomal mutation may protect a bacterial cell by changing the binding site of an antibiotic but may result in slower growth rate. Moreover, some adaptive mutations can propagate not only through inheritance but also through horizontal gene transfer. The most common mechanism of horizontal gene transfer is the transferring of plasmids carrying antibiotic resistance genes between bacteria of the same or different species via conjugation. However, bacteria can also acquire resistance through transformation, as in Streptococcus pneumoniae uptaking of naked fragments of extracellular DNA that contain antibiotic resistance genes to streptomycin, through transduction, as in the bacteriophage-mediated transfer of tetracycline resistance genes between strains of S. pyogenes, or through gene transfer agents, which are particles produced by the host cell that resemble bacteriophage structures and are capable of transferring DNA. + +Antibiotic resistance can be introduced artificially into a microorganism through laboratory protocols, sometimes used as a selectable marker to examine the mechanisms of gene transfer or to identify individuals that absorbed a piece of DNA that included the resistance gene and another gene of interest. + +Recent findings show no necessity of large populations of bacteria for the appearance of antibiotic resistance. Small populations of Escherichia coli in an antibiotic gradient can become resistant. Any heterogeneous environment with respect to nutrient and antibiotic gradients may facilitate antibiotic resistance in small bacterial populations. Researchers hypothesize that the mechanism of resistance evolution is based on four SNP mutations in the genome of E. coli produced by the gradient of antibiotic. + +In one study, which has implications for space microbiology, a non-pathogenic strain E. coli MG1655 was exposed to trace levels of the broad spectrum antibiotic chloramphenicol, under simulated microgravity (LSMMG, or Low Shear Modeled Microgravity) over 1000 generations. The adapted strain acquired resistance to not only chloramphenicol, but also cross-resistance to other antibiotics; this was in contrast to the observation on the same strain, which was adapted to over 1000 generations under LSMMG, but without any antibiotic exposure; the strain in this case did not acquire any such resistance. Thus, irrespective of where they are used, the use of an antibiotic would likely result in persistent resistance to that antibiotic, as well as cross-resistance to other antimicrobials. + +In recent years, the emergence and spread of β-lactamases called carbapenemases has become a major health crisis. One such carbapenemase is New Delhi metallo-beta-lactamase 1 (NDM-1), an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics. The most common bacteria that make this enzyme are gram-negative such as E. coli and Klebsiella pneumoniae, but the gene for NDM-1 can spread from one strain of bacteria to another by horizontal gene transfer. + +Viruses +Specific antiviral drugs are used to treat some viral infections. These drugs prevent viruses from reproducing by inhibiting essential stages of the virus's replication cycle in infected cells. Antivirals are used to treat HIV, hepatitis B, hepatitis C, influenza, herpes viruses including varicella zoster virus, cytomegalovirus and Epstein–Barr virus. With each virus, some strains have become resistant to the administered drugs. + +Antiviral drugs typically target key components of viral reproduction; for example, oseltamivir targets influenza neuraminidase, while guanosine analogs inhibit viral DNA polymerase. Resistance to antivirals is thus acquired through mutations in the genes that encode the protein targets of the drugs. + +Resistance to HIV antivirals is problematic, and even multi-drug resistant strains have evolved. One source of resistance is that many current HIV drugs, including NRTIs and NNRTIs, target reverse transcriptase; however, HIV-1 reverse transcriptase is highly error prone and thus mutations conferring resistance arise rapidly. Resistant strains of the HIV virus emerge rapidly if only one antiviral drug is used. Using three or more drugs together, termed combination therapy, has helped to control this problem, but new drugs are needed because of the continuing emergence of drug-resistant HIV strains. + +Fungi +Infections by fungi are a cause of high morbidity and mortality in immunocompromised persons, such as those with HIV/AIDS, tuberculosis or receiving chemotherapy. The fungi Candida, Cryptococcus neoformans and Aspergillus fumigatus cause most of these infections and antifungal resistance occurs in all of them. Multidrug resistance in fungi is increasing because of the widespread use of antifungal drugs to treat infections in immunocompromised individuals and the use of some agricultural antifungals. Antifungal resistant disease is associated with increased mortality. + +Some fungi (e.g. Candida krusei and fluconazole) exhibit intrinsic resistance to certain antifungal drugs or classes, whereas some species develop antifungal resistance to external pressures. Antifungal resistance is a One Health concern, driven by multiple extrinsic factors, including extensive fungicidal use, overuse of clinical antifungals, environmental change and host factors. + +In the USA fluconazole-resistant Candida species and azole resistance in Aspergillus fumigatus have been highlighted as a growing threat. + +More than 20 species of Candida can cause candidiasis infection, the most common of which is Candida albicans. Candida yeasts normally inhabit the skin and mucous membranes without causing infection. However, overgrowth of Candida can lead to candidiasis. Some Candida species (e.g. Candida glabrata) are becoming resistant to first-line and second-line antifungal agents such as echinocandins and azoles. + +The emergence of Candida auris as a potential human pathogen that sometimes exhibits multi-class antifungal drug resistance is concerning and has been associated with several outbreaks globally. The WHO has released a priority fungal pathogen list, including pathogens with antifungal resistance. + +The identification of antifungal resistance is undermined by limited classical diagnosis of infection, where a culture is lacking, preventing susceptibility testing. National and international surveillance schemes for fungal disease and antifungal resistance are limited, hampering the understanding of the disease burden and associated resistance. The application of molecular testing to identify genetic markers associating with resistance may improve the identification of antifungal resistance, but the diversity of mutations associated with resistance is increasing across the fungal species causing infection. In addition, a number of resistance mechanisms depend on up-regulation of selected genes (for instance reflux pumps) rather than defined mutations that are amenable to molecular detection. + +Due to the limited number of antifungals in clinical use and the increasing global incidence of antifungal resistance, using the existing antifungals in combination might be beneficial in some cases but further research is needed. Similarly, other approaches that might help to combat the emergence of antifungal resistance could rely on the development of host-directed therapies such as immunotherapy or vaccines. + +Parasites + +The protozoan parasites that cause the diseases malaria, trypanosomiasis, toxoplasmosis, cryptosporidiosis and leishmaniasis are important human pathogens. + +Malarial parasites that are resistant to the drugs that are currently available to infections are common and this has led to increased efforts to develop new drugs. Resistance to recently developed drugs such as artemisinin has also been reported. The problem of drug resistance in malaria has driven efforts to develop vaccines. + +Trypanosomes are parasitic protozoa that cause African trypanosomiasis and Chagas disease (American trypanosomiasis). There are no vaccines to prevent these infections so drugs such as pentamidine and suramin, benznidazole and nifurtimox are used to treat infections. These drugs are effective but infections caused by resistant parasites have been reported. + +Leishmaniasis is caused by protozoa and is an important public health problem worldwide, especially in sub-tropical and tropical countries. Drug resistance has "become a major concern". + +Global and genomic data + +In 2022, genomic epidemiologists reported results from a global survey of antimicrobial resistance via genomic wastewater-based epidemiology, finding large regional variations, providing maps, and suggesting resistance genes are also passed on between microbial species that are not closely related. The WHO provides the Global Antimicrobial Resistance and Use Surveillance System (GLASS) reports which summarize annual (e.g. 2020's) data on international AMR, also including an interactive dashboard. + +Epidemiology + +United Kingdom +Public Health England reported that the total number of antibiotic resistant infections in England rose by 9% from 55,812 in 2017 to 60,788 in 2018, but antibiotic consumption had fallen by 9% from 20.0 to 18.2 defined daily doses per 1,000 inhabitants per day between 2014 and 2018. + +United States +The Centers for Disease Control and Prevention reported that more than 2.8 million cases of antibiotic resistance have been reported. However, in 2019 overall deaths from antibiotic-resistant infections decreased by 18% and deaths in hospitals decreased by 30%. + +The COVID pandemic caused a reversal of much of the progress made on attenuating the effects of antibiotic resistance, resulting in more antibiotic use, more resistant infections, and less data on preventative action. Hospital-onset infections and deaths both increased by 15% in 2020, and significantly higher rates of infections were reported for 4 out of 6 types of healthcare associated infections. + +History +The 1950s to 1970s represented the golden age of antibiotic discovery, where countless new classes of antibiotics were discovered to treat previously incurable diseases such as tuberculosis and syphilis. However, since that time the discovery of new classes of antibiotics has been almost nonexistent, and represents a situation that is especially problematic considering the resiliency of bacteria shown over time and the continued misuse and overuse of antibiotics in treatment. + +The phenomenon of antimicrobial resistance caused by overuse of antibiotics was predicted as early as 1945 by Alexander Fleming who said "The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily under-dose himself and by exposing his microbes to nonlethal quantities of the drug make them resistant." Without the creation of new and stronger antibiotics an era where common infections and minor injuries can kill, and where complex procedures such as surgery and chemotherapy become too risky, is a very real possibility. Antimicrobial resistance can lead to epidemics of enormous proportions if preventive actions are not taken. In this day and age current antimicrobial resistance leads to longer hospital stays, higher medical costs, and increased mortality. + +Society and culture + +Innovation policy +Since the mid-1980s pharmaceutical companies have invested in medications for cancer or chronic disease that have greater potential to make money and have "de-emphasized or dropped development of antibiotics". On 20 January 2016 at the World Economic Forum in Davos, Switzerland, more than "80 pharmaceutical and diagnostic companies" from around the world called for "transformational commercial models" at a global level to spur research and development on antibiotics and on the "enhanced use of diagnostic tests that can rapidly identify the infecting organism". A number of countries are considering or implementing delinked payment models for new antimicrobials whereby payment is based on value rather than volume of drug sales. This offers the opportunity to pay for valuable new drugs even if they are reserved for use in relatively rare drug resistant infections. + +Legal frameworks +Some global health scholars have argued that a global, legal framework is needed to prevent and control antimicrobial resistance. For instance, binding global policies could be used to create antimicrobial use standards, regulate antibiotic marketing, and strengthen global surveillance systems. Ensuring compliance of involved parties is a challenge. Global antimicrobial resistance policies could take lessons from the environmental sector by adopting strategies that have made international environmental agreements successful in the past such as: sanctions for non-compliance, assistance for implementation, majority vote decision-making rules, an independent scientific panel, and specific commitments. + +United States + +For the United States 2016 budget, U.S. president Barack Obama proposed to nearly double the amount of federal funding to "combat and prevent" antibiotic resistance to more than $1.2 billion. Many international funding agencies like USAID, DFID, SIDA and Bill & Melinda Gates Foundation have pledged money for developing strategies to counter antimicrobial resistance. + +On 27 March 2015, the White House released a comprehensive plan to address the increasing need for agencies to combat the rise of antibiotic-resistant bacteria. The Task Force for Combating Antibiotic-Resistant Bacteria developed The National Action Plan for Combating Antibiotic-Resistant Bacteria with the intent of providing a roadmap to guide the US in the antibiotic resistance challenge and with hopes of saving many lives. This plan outlines steps taken by the Federal government over the next five years needed in order to prevent and contain outbreaks of antibiotic-resistant infections; maintain the efficacy of antibiotics already on the market; and to help to develop future diagnostics, antibiotics, and vaccines. + +The Action Plan was developed around five goals with focuses on strengthening health care, public health veterinary medicine, agriculture, food safety and research, and manufacturing. These goals, as listed by the White House, are as follows: + Slow the Emergence of Resistant Bacteria and Prevent the Spread of Resistant Infections + Strengthen National One-Health Surveillance Efforts to Combat Resistance + Advance Development and use of Rapid and Innovative Diagnostic Tests for Identification and Characterization of Resistant Bacteria + Accelerate Basic and Applied Research and Development for New Antibiotics, Other Therapeutics, and Vaccines + Improve International Collaboration and Capacities for Antibiotic Resistance Prevention, Surveillance, Control and Antibiotic Research and Development +The following are goals set to meet by 2020: + Establishment of antimicrobial programs within acute care hospital settings + Reduction of inappropriate antibiotic prescription and use by at least 50% in outpatient settings and 20% inpatient settings + Establishment of State Antibiotic Resistance (AR) Prevention Programs in all 50 states + Elimination of the use of medically important antibiotics for growth promotion in food-producing animals. + +Policies +According to World Health Organization, policymakers can help tackle resistance by strengthening resistance-tracking and laboratory capacity and by regulating and promoting the appropriate use of medicines. Policymakers and industry can help tackle resistance by: fostering innovation and research and development of new tools; and promoting cooperation and information sharing among all stakeholders. + +Policy evaluation +Measuring the costs and benefits of strategies to combat AMR is difficult and policies may only have effects in the distant future. In other infectious diseases this problem has been addressed by using mathematical models. More research is needed to understand how AMR develops and spreads so that mathematical modelling can be used to anticipate the likely effects of different policies. + +Further research + +Rapid testing and diagnostics + +Distinguishing infections requiring antibiotics from self-limiting ones is clinically challenging. In order to guide appropriate use of antibiotics and prevent the evolution and spread of antimicrobial resistance, diagnostic tests that provide clinicians with timely, actionable results are needed. + +Acute febrile illness is a common reason for seeking medical care worldwide and a major cause of morbidity and mortality. In areas with decreasing malaria incidence, many febrile patients are inappropriately treated for malaria, and in the absence of a simple diagnostic test to identify alternative causes of fever, clinicians presume that a non-malarial febrile illness is most likely a bacterial infection, leading to inappropriate use of antibiotics. Multiple studies have shown that the use of malaria rapid diagnostic tests without reliable tools to distinguish other fever causes has resulted in increased antibiotic use. + +Antimicrobial susceptibility testing (AST) can facilitate a precision medicine approach to treatment by helping clinicians to prescribe more effective and targeted antimicrobial therapy. At the same time with traditional phenotypic AST it can take 12 to 48 hours to obtain a result due to the time taken for organisms to grow on/in culture media. Rapid testing, possible from molecular diagnostics innovations, is defined as "being feasible within an 8-h working shift". There are several commercial Food and Drug Administration-approved assays available which can detect AMR genes from a variety of specimen types. Progress has been slow due to a range of reasons including cost and regulation. Genotypic AMR characterisation methods are, however, being increasingly used in combination with machine learning algorithms in research to help better predict phenotypic AMR from organism genotype. + +Optical techniques such as phase contrast microscopy in combination with single-cell analysis are another powerful method to monitor bacterial growth. In 2017, scientists from Sweden published a method that applies principles of microfluidics and cell tracking, to monitor bacterial response to antibiotics in less than 30 minutes overall manipulation time. Recently, this platform has been advanced by coupling microfluidic chip with optical tweezing in order to isolate bacteria with altered phenotype directly from the analytical matrix. + +Rapid diagnostic methods have also been trialled as antimicrobial stewardship interventions to influence the healthcare drivers of AMR. Serum procalcitonin measurement has been shown to reduce mortality rate, antimicrobial consumption and antimicrobial-related side-effects in patients with respiratory infections, but impact on AMR has not yet been demonstrated. Similarly, point of care serum testing of the inflammatory biomarker C-reactive protein has been shown to influence antimicrobial prescribing rates in this patient cohort, but further research is required to demonstrate an effect on rates of AMR. Clinical investigation to rule out bacterial infections are often done for patients with pediatric acute respiratory infections. Currently it is unclear if rapid viral testing affects antibiotic use in children. + +Vaccines +Microorganisms usually do not develop resistance to vaccines because vaccines reduce the spread of the infection and target the pathogen in multiple ways in the same host and possibly in different ways between different hosts. Furthermore, if the use of vaccines increases, there is evidence that antibiotic resistant strains of pathogens will decrease; the need for antibiotics will naturally decrease as vaccines prevent infection before it occurs. However, there are well documented cases of vaccine resistance, although these are usually much less of a problem than antimicrobial resistance. + +While theoretically promising, antistaphylococcal vaccines have shown limited efficacy, because of immunological variation between Staphylococcus species, and the limited duration of effectiveness of the antibodies produced. Development and testing of more effective vaccines is underway. + +Two registrational trials have evaluated vaccine candidates in active immunization strategies against S. aureus infection. In a phase II trial, a bivalent vaccine of capsular proteins 5 & 8 was tested in 1804 hemodialysis patients with a primary fistula or synthetic graft vascular access. After 40 weeks following vaccination a protective effect was seen against S. aureus bacteremia, but not at 54 weeks following vaccination. Based on these results, a second trial was conducted which failed to show efficacy. + +Merck tested V710, a vaccine targeting IsdB, in a blinded randomized trial in patients undergoing median sternotomy. The trial was terminated after a higher rate of multiorgan system failure–related deaths was found in the V710 recipients. Vaccine recipients who developed S. aureus infection were five times more likely to die than control recipients who developed S. aureus infection. + +Numerous investigators have suggested that a multiple-antigen vaccine would be more effective, but a lack of biomarkers defining human protective immunity keep these proposals in the logical, but strictly hypothetical arena. + +Alternating therapy +Alternating therapy is a proposed method in which two or three antibiotics are taken in a rotation versus taking just one antibiotic such that bacteria resistant to one antibiotic are killed when the next antibiotic is taken. Studies have found that this method reduces the rate at which antibiotic resistant bacteria emerge in vitro relative to a single drug for the entire duration. + +Studies have found that bacteria that evolve antibiotic resistance towards one group of antibiotic may become more sensitive to others. This phenomenon can be used to select against resistant bacteria using an approach termed collateral sensitivity cycling, which has recently been found to be relevant in developing treatment strategies for chronic infections caused by Pseudomonas aeruginosa. Despite its promise, large-scale clinical and experimental studies revealed limited evidence of susceptibility to antibiotic cycling across various pathogens. + +Development of new drugs +Since the discovery of antibiotics, research and development (R&D) efforts have provided new drugs in time to treat bacteria that became resistant to older antibiotics, but in the 2000s there has been concern that development has slowed enough that seriously ill people may run out of treatment options. Another concern is that practitioners may become reluctant to perform routine surgeries because of the increased risk of harmful infection. Backup treatments can have serious side-effects; for example, antibiotics like aminoglycosides (such as amikacin, gentamicin, kanamycin, streptomycin, etc.) used for the treatment of drug-resistant tuberculosis and cystic fibrosis can cause respiratory disorders, deafness and kidney failure. + +The potential crisis at hand is the result of a marked decrease in industry research and development. Poor financial investment in antibiotic research has exacerbated the situation. The pharmaceutical industry has little incentive to invest in antibiotics because of the high risk and because the potential financial returns are less likely to cover the cost of development than for other pharmaceuticals. In 2011, Pfizer, one of the last major pharmaceutical companies developing new antibiotics, shut down its primary research effort, citing poor shareholder returns relative to drugs for chronic illnesses. However, small and medium-sized pharmaceutical companies are still active in antibiotic drug research. In particular, apart from classical synthetic chemistry methodologies, researchers have developed a combinatorial synthetic biology platform on single cell level in a high-throughput screening manner to diversify novel lanthipeptides. + +In the 5–10 years since 2010, there has been a significant change in the ways new antimicrobial agents are discovered and developed – principally via the formation of public-private funding initiatives. These include CARB-X, which focuses on nonclinical and early phase development of novel antibiotics, vaccines, rapid diagnostics; Novel Gram Negative Antibiotic (GNA-NOW), which is part of the EU's Innovative Medicines Initiative; and Replenishing and Enabling the Pipeline for Anti-infective Resistance Impact Fund (REPAIR). Later stage clinical development is supported by the AMR Action Fund, which in turn is supported by multiple investors with the aim of developing 2-4 new antimicrobial agents by 2030. The delivery of these trials is facilitated by national and international networks supported by the Clinical Research Network of the National Institute for Health and Care Research (NIHR), European Clinical Research Alliance in Infectious Diseases (ECRAID) and the recently formed ADVANCE-ID, which is a clinical research network based in Asia. The Global Antimicrobial Research and Development Partnership (GARDP) is generating new evidence for global AMR threats such as neonatal sepsis, treatment of serious bacterial infections and sexually transmitted infections as well as addressing global access to new and strategically important antibacterial drugs. + +The discovery and development of new antimicrobial agents has been facilitated by regulatory advances, which have been principally led by the European Medicines Agency (EMA) and the Food and Drug Administration (FDA). These processes are increasingly aligned although important differences remain and drug developers must prepare separate documents. New development pathways have been developed to help with the approval of new antimicrobial agents that address unmet needs such as the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD). These new pathways are required because of difficulties in conducting large definitive phase III clinical trials in a timely way. + +Some of the economic impediments to the development of new antimicrobial agents have been addressed by innovative reimbursement schemes that delink payment of antimicrobials from volume-based sales. In the UK, a market entry reward scheme has been pioneered by the National Institute for Clinical Excellence (NICE) whereby an annual subscription fee is paid for use of strategically valuable antimicrobial agents – cefiderocol and ceftazidime-aviabactam are the first agents to be used in this manner and the scheme is potential blueprint for comparable programs in other countries. + +The available classes of antifungal drugs are still limited but as of 2021 novel classes of antifungals are being developed and are undergoing various stages of clinical trials to assess performance. + +Scientists have started using advanced computational approaches with supercomputers for the development of new antibiotic derivatives to deal with antimicrobial resistance. + +Biomaterials +Using antibiotic-free alternatives in bone infection treatment may help decrease the use of antibiotics and thus antimicrobial resistance. The bone regeneration material bioactive glass S53P4 has shown to effectively inhibit the bacterial growth of up to 50 clinically relevant bacteria including MRSA and MRSE. + +Nanomaterials + +During the last decades, copper and silver nanomaterials have demonstrated appealing features for the development of a new family of antimicrobial agents. + +Rediscovery of ancient treatments +Similar to the situation in malaria therapy, where successful treatments based on ancient recipes have been found, there has already been some success in finding and testing ancient drugs and other treatments that are effective against AMR bacteria. + +Computational community surveillance +One of the key tools identified by the WHO and others for the fight against rising antimicrobial resistance is improved surveillance of the spread and movement of AMR genes through different communities and regions. Recent advances in high-throughput DNA sequencing as a result of the Human Genome Project have resulted in the ability to determine the individual microbial genes in a sample. Along with the availability of databases of known antimicrobial resistance genes, such as the Comprehensive Antimicrobial Resistance Database (CARD) and ResFinder, this allows the identification of all the antimicrobial resistance genes within the sample - the so-called “resistome”. In doing so, a profile of these genes within a community or environment can be determined, providing insights into how antimicrobial resistance is spreading through a population and allowing for the identification of resistance that is of concern. + +Phage therapy + +Phage therapy is the therapeutic use of bacteriophages to treat pathogenic bacterial infections. Phage therapy has many potential applications in human medicine as well as dentistry, veterinary science, and agriculture. + +Phage therapy relies on the use of naturally occurring bacteriophages to infect and lyse bacteria at the site of infection in a host. Due to current advances in genetics and biotechnology these bacteriophages can possibly be manufactured to treat specific infections. Phages can be bioengineered to target multidrug-resistant bacterial infections, and their use involves the added benefit of preventing the elimination of beneficial bacteria in the human body. Phages destroy bacterial cell walls and membrane through the use of lytic proteins which kill bacteria by making many holes from the inside out. Bacteriophages can even possess the ability to digest the biofilm that many bacteria develop that protect them from antibiotics in order to effectively infect and kill bacteria. Bioengineering can play a role in creating successful bacteriophages. + +Understanding the mutual interactions and evolutions of bacterial and phage populations in the environment of a human or animal body is essential for rational phage therapy. + +Bacteriophagics are used against antibiotic resistant bacteria in Georgia (George Eliava Institute) and in one institute in Wrocław, Poland. Bacteriophage cocktails are common drugs sold over the counter in pharmacies in eastern countries. In Belgium, four patients with severe musculoskeletal infections received bacteriophage therapy with concomitant antibiotics. After a single course of phage therapy, no recurrence of infection occurred and no severe side-effects related to the therapy were detected. + +See also + +References + +Books + +Journals + + + + + + + + 16-minute film about a post-antibiotic world.

Nathaniel Martin (Universiteit Leiden) + + +Evolutionary biology +Health disasters +Pharmaceuticals policy +Veterinary medicine +Global issues +In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body may trigger an immune response. + +Antigens can be proteins, peptides (amino acid chains), polysaccharides (chains of simple sugars), lipids, or nucleic acids. Antigens exist on normal cells, cancer cells, parasites, viruses, fungi, and bacteria. + +Antigens are recognized by antigen receptors, including antibodies and T-cell receptors. Diverse antigen receptors are made by cells of the immune system so that each cell has a specificity for a single antigen. Upon exposure to an antigen, only the lymphocytes that recognize that antigen are activated and expanded, a process known as clonal selection. In most cases, antibodies are antigen-specific, meaning that an antibody can only react to and bind one specific antigen; in some instances, however, antibodies may cross-react to bind more than one antigen. The reaction between an antigen and an antibody is called the antigen-antibody reaction. + +Antigen can originate either from within the body ("self-protein" or "self antigens") or from the external environment ("non-self"). The immune system identifies and attacks "non-self" external antigens. Antibodies usually do not react with self-antigens due to negative selection of T cells in the thymus and B cells in the bone marrow. The diseases in which antibodies react with self antigens and damage the body's own cells are called autoimmune diseases. + +Vaccines are examples of antigens in an immunogenic form, which are intentionally administered to a recipient to induce the memory function of the adaptive immune system towards antigens of the pathogen invading that recipient. The vaccine for seasonal influenza is a common example. + +Etymology +Paul Ehrlich coined the term antibody () in his side-chain theory at the end of the 19th century. In 1899, Ladislas Deutsch (László Detre) named the hypothetical substances halfway between bacterial constituents and antibodies "antigenic or immunogenic substances" (). He originally believed those substances to be precursors of antibodies, just as a zymogen is a precursor of an enzyme. But, by 1903, he understood that an antigen induces the production of immune bodies (antibodies) and wrote that the word antigen is a contraction of antisomatogen (). The Oxford English Dictionary indicates that the logical construction should be "anti(body)-gen". +The term originally referred to a substance that acts as an antibody generator. + +Terminology + Epitope – the distinct surface features of an antigen, its antigenic determinant.Antigenic molecules, normally "large" biological polymers, usually present surface features that can act as points of interaction for specific antibodies. Any such feature constitutes an epitope. Most antigens have the potential to be bound by multiple antibodies, each of which is specific to one of the antigen's epitopes. Using the "lock and key" metaphor, the antigen can be seen as a string of keys (epitopes) each of which matches a different lock (antibody). Different antibody idiotypes, each have distinctly formed complementarity-determining regions. + Allergen – A substance capable of causing an allergic reaction. The (detrimental) reaction may result after exposure via ingestion, inhalation, injection, or contact with skin. + Superantigen – A class of antigens that cause non-specific activation of T-cells, resulting in polyclonal T-cell activation and massive cytokine release. + Tolerogen – A substance that invokes a specific immune non-responsiveness due to its molecular form. If its molecular form is changed, a tolerogen can become an immunogen. + Immunoglobulin-binding protein – Proteins such as protein A, protein G, and protein L that are capable of binding to antibodies at positions outside of the antigen-binding site. While antigens are the "target" of antibodies, immunoglobulin-binding proteins "attack" antibodies. + T-dependent antigen – Antigens that require the assistance of T cells to induce the formation of specific antibodies. + T-independent antigen – Antigens that stimulate B cells directly. + Immunodominant antigens – Antigens that dominate (over all others from a pathogen) in their ability to produce an immune response. T cell responses typically are directed against a relatively few immunodominant epitopes, although in some cases (e.g., infection with the malaria pathogen Plasmodium spp.) it is dispersed over a relatively large number of parasite antigens. + +Antigen-presenting cells present antigens in the form of peptides on histocompatibility molecules. The T cells selectively recognize the antigens; depending on the antigen and the type of the histocompatibility molecule, different types of T cells will be activated. For T-cell receptor (TCR) recognition, the peptide must be processed into small fragments inside the cell and presented by a major histocompatibility complex (MHC). The antigen cannot elicit the immune response without the help of an immunologic adjuvant. Similarly, the adjuvant component of vaccines plays an essential role in the activation of the innate immune system. + +An immunogen is an antigen substance (or adduct) that is able to trigger a humoral (innate) or cell-mediated immune response. It first initiates an innate immune response, which then causes the activation of the adaptive immune response. An antigen binds the highly variable immunoreceptor products (B-cell receptor or T-cell receptor) once these have been generated. Immunogens are those antigens, termed immunogenic, capable of inducing an immune response. + +At the molecular level, an antigen can be characterized by its ability to bind to an antibody's paratopes. Different antibodies have the potential to discriminate among specific epitopes present on the antigen surface. A hapten is a small molecule that can only induce an immune response when attached to a larger carrier molecule, such as a protein. Antigens can be proteins, polysaccharides, lipids, nucleic acids or other biomolecules. This includes parts (coats, capsules, cell walls, flagella, fimbriae, and toxins) of bacteria, viruses, and other microorganisms. Non-microbial non-self antigens can include pollen, egg white, and proteins from transplanted tissues and organs or on the surface of transfused blood cells. + +Sources +Antigens can be classified according to their source. + +Exogenous antigens +Exogenous antigens are antigens that have entered the body from the outside, for example, by inhalation, ingestion or injection. The immune system's response to exogenous antigens is often subclinical. By endocytosis or phagocytosis, exogenous antigens are taken into the antigen-presenting cells (APCs) and processed into fragments. APCs then present the fragments to T helper cells (CD4+) by the use of class II histocompatibility molecules on their surface. Some T cells are specific for the peptide:MHC complex. They become activated and start to secrete cytokines, substances that activate cytotoxic T lymphocytes (CTL), antibody-secreting B cells, macrophages and other particles. + +Some antigens start out as exogenous and later become endogenous (for example, intracellular viruses). Intracellular antigens can be returned to circulation upon the destruction of the infected cell. + +Endogenous antigens +Endogenous antigens are generated within normal cells as a result of normal cell metabolism, or because of viral or intracellular bacterial infection. The fragments are then presented on the cell surface in the complex with MHC class I molecules. If activated cytotoxic CD8+ T cells recognize them, the T cells secrete various toxins that cause the lysis or apoptosis of the infected cell. In order to keep the cytotoxic cells from killing cells just for presenting self-proteins, the cytotoxic cells (self-reactive T cells) are deleted as a result of tolerance (negative selection). Endogenous antigens include xenogenic (heterologous), autologous and idiotypic or allogenic (homologous) antigens. Sometimes antigens are part of the host itself in an autoimmune disease. + +Autoantigens +An autoantigen is usually a self-protein or protein complex (and sometimes DNA or RNA) that is recognized by the immune system of patients with a specific autoimmune disease. Under normal conditions, these self-proteins should not be the target of the immune system, but in autoimmune diseases, their associated T cells are not deleted and instead attack. + +Neoantigens +Neoantigens are those that are entirely absent from the normal human genome. As compared with nonmutated self-proteins, neoantigens are of relevance to tumor control, as the quality of the T cell pool that is available for these antigens is not affected by central T cell tolerance. Technology to systematically analyze T cell reactivity against neoantigens became available only recently. Neoantigens can be directly detected and quantified. + +Viral antigens +For virus-associated tumors, such as cervical cancer and a subset of head and neck cancers, epitopes derived from viral open reading frames contribute to the pool of neoantigens. + +Tumor antigens +Tumor antigens are those antigens that are presented by MHC class I or MHC class II molecules on the surface of tumor cells. Antigens found only on such cells are called tumor-specific antigens (TSAs) and generally result from a tumor-specific mutation. More common are antigens that are presented by tumor cells and normal cells, called tumor-associated antigens (TAAs). Cytotoxic T lymphocytes that recognize these antigens may be able to destroy tumor cells. + +Tumor antigens can appear on the surface of the tumor in the form of, for example, a mutated receptor, in which case they are recognized by B cells. + +For human tumors without a viral etiology, novel peptides (neo-epitopes) are created by tumor-specific DNA alterations. + +Process +A large fraction of human tumor mutations are effectively patient-specific. Therefore, neoantigens may also be based on individual tumor genomes. Deep-sequencing technologies can identify mutations within the protein-coding part of the genome (the exome) and predict potential neoantigens. In mice models, for all novel protein sequences, potential MHC-binding peptides were predicted. The resulting set of potential neoantigens was used to assess T cell reactivity. Exome–based analyses were exploited in a clinical setting, to assess reactivity in patients treated by either tumor-infiltrating lymphocyte (TIL) cell therapy or checkpoint blockade. Neoantigen identification was successful for multiple experimental model systems and human malignancies. + +The false-negative rate of cancer exome sequencing is low—i.e.: the majority of neoantigens occur within exonic sequence with sufficient coverage. However, the vast majority of mutations within expressed genes do not produce neoantigens that are recognized by autologous T cells. + +As of 2015 mass spectrometry resolution is insufficient to exclude many false positives from the pool of peptides that may be presented by MHC molecules. Instead, algorithms are used to identify the most likely candidates. These algorithms consider factors such as the likelihood of proteasomal processing, transport into the endoplasmic reticulum, affinity for the relevant MHC class I alleles and gene expression or protein translation levels. + +The majority of human neoantigens identified in unbiased screens display a high predicted MHC binding affinity. Minor histocompatibility antigens, a conceptually similar antigen class are also correctly identified by MHC binding algorithms. Another potential filter examines whether the mutation is expected to improve MHC binding. The nature of the central TCR-exposed residues of MHC-bound peptides is associated with peptide immunogenicity. + +Nativity +A native antigen is an antigen that is not yet processed by an APC to smaller parts. T cells cannot bind native antigens, but require that they be processed by APCs, whereas B cells can be activated by native ones. + +Antigenic specificity +Antigenic specificity is the ability of the host cells to recognize an antigen specifically as a unique molecular entity and distinguish it from another with exquisite precision. Antigen specificity is due primarily to the side-chain conformations of the antigen. It is measurable and need not be linear or of a rate-limited step or equation. Both T cells and B cells are cellular components of adaptive immunity. + +See also + +References + + +Immune system +Biomolecules +An autosome is any chromosome that is not a sex chromosome. The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal (sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. + +For example, humans have a diploid genome that usually contains 22 pairs of autosomes and one allosome pair (46 chromosomes total). The autosome pairs are labeled with numbers (1–22 in humans) roughly in order of their sizes in base pairs, while allosomes are labelled with their letters. By contrast, the allosome pair consists of two X chromosomes in females or one X and one Y chromosome in males. Unusual combinations of XYY, XXY, XXX, XXXX, XXXXX or XXYY, among other Salome combinations, are known to occur and usually cause developmental abnormalities. + +Autosomes still contain sexual determination genes even though they are not sex chromosomes. For example, the SRY gene on the Y chromosome encodes the transcription factor TDF and is vital for male sex determination during development. TDF functions by activating the SOX9 gene on chromosome 17, so mutations of the SOX9 gene can cause humans with an ordinary Y chromosome to develop as females. + +All human autosomes have been identified and mapped by extracting the chromosomes from a cell arrested in metaphase or prometaphase and then staining them with a type of dye (most commonly, Giemsa). These chromosomes are typically viewed as karyograms for easy comparison. Clinical geneticists can compare the karyogram of an individual to a reference karyogram to discover the cytogenetic basis of certain phenotypes. For example, the karyogram of someone with Patau Syndrome would show that they possess three copies of chromosome 13. Karyograms and staining techniques can only detect large-scale disruptions to chromosomes—chromosomal aberrations smaller than a few million base pairs generally cannot be seen on a karyogram. + +Autosomal genetic disorders + +Autosomal genetic disorders can arise due to a number of causes, some of the most common being nondisjunction in parental germ cells or Mendelian inheritance of deleterious alleles from parents. Autosomal genetic disorders which exhibit Mendelian inheritance can be inherited either in an autosomal dominant or recessive fashion. These disorders manifest in and are passed on by either sex with equal frequency. Autosomal dominant disorders are often present in both parent and child, as the child needs to inherit only one copy of the deleterious allele to manifest the disease. Autosomal recessive diseases, however, require two copies of the deleterious allele for the disease to manifest. Because it is possible to possess one copy of a deleterious allele without presenting a disease phenotype, two phenotypically normal parents can have a child with the disease if both parents are carriers (also known as heterozygotes) for the condition. + +Autosomal aneuploidy can also result in disease conditions. Aneuploidy of autosomes is not well tolerated and usually results in miscarriage of the developing fetus. Fetuses with aneuploidy of gene-rich chromosomes—such as chromosome 1—never survive to term, and fetuses with aneuploidy of gene-poor chromosomes—such as chromosome 21— are still miscarried over 23% of the time. Possessing a single copy of an autosome (known as a monosomy) is nearly always incompatible with life, though very rarely some monosomies can survive past birth. Having three copies of an autosome (known as a trisomy) is far more compatible with life, however. A common example is Down syndrome, which is caused by possessing three copies of chromosome 21 instead of the usual two. + +Partial aneuploidy can also occur as a result of unbalanced translocations during meiosis. Deletions of part of a chromosome cause partial monosomies, while duplications can cause partial trisomies. If the duplication or deletion is large enough, it can be discovered by analyzing a karyogram of the individual. Autosomal translocations can be responsible for a number of diseases, ranging from cancer to schizophrenia. Unlike single gene disorders, diseases caused by aneuploidy are the result of improper gene dosage, not nonfunctional gene product. + +See also + Aneuploidy (abnormal number of chromosomes) + Autosomal dominant + Autosomal recessive + Homologous chromosome + Pseudoautosomal region + XY sex-determination system +Genetic disorder + +References + +Chromosomes +Cytogenetics +Antwerp is a city in Belgium and capital of the Antwerp province. + +Antwerp may also refer to: + +In Belgium + Antwerp (district) + Antwerp (province) + +In the United States + Antwerp, Ohio + Antwerp Township, Michigan + Antwerp, New York + Antwerp (village), New York + +In Australia +Antwerp, Victoria + +Other +Port of Antwerp +Royal Antwerp FC, a football club +Antwerp (novel), by Roberto Bolaño +Antwerp, a poem by Ford Madox Ford + +See also +Aquila may refer to: + +Arts, entertainment, and media + + Aquila, a series of books by S.P.

Its members are mostly composed of Arabs, but also include other peoples. Al-Qaeda has mounted attacks on civilian, economic and military targets of America and its allies; such as the USS Cole bombing, 1998 US embassy bombings and the September 11 attacks. The organization is designated as a terrorist group by NATO, UN Security Council, the European Union, and various countries around the world. + +The organization was founded in a series of meetings held in Peshawar during 1988, attended by Abdullah Azzam, Osama bin Laden, Muhammad Atef, Ayman al-Zawahiri and other veterans of the Soviet–Afghan War. Building upon the networks of Maktab al-Khidamat, the founding members decided to create an organization named "Al-Qaeda" to serve as a "vanguard" for jihad. When Saddam Hussein invaded and occupied Kuwait in 1990, bin Laden offered to support Saudi Arabia by sending his Mujahideen fighters. His offer was rebuffed by the Saudi government, which instead sought the aid of the United States. The stationing of U.S. troops in Arabian Peninsula prompted bin Laden to declare a jihad against the Saudi rulers, whom he denounced as murtadd (apostates), and against the US. During 1992–1996, Al-Qaeda established its headquarters in Sudan until it was expelled in 1996. It shifted its base to the Taliban-ruled Afghanistan and later expanded to other parts of the world, primarily in the Middle East and South Asia. In 1996 and 1998, bin Laden issued two fatāwā that demanded the withdrawal of U.S. troops from Saudi Arabia. + +In 1998, Al-Qaeda conducted the US embassy bombings in Kenya and Tanzania, which killed 224 people. The U.S. retaliated by launching Operation Infinite Reach, against al-Qaeda targets in Afghanistan and Sudan. In 2001, Al-Qaeda carried out the September 11 attacks, resulting in nearly 3,000 deaths, long-term health consequences of nearby residents, damaging global economic markets, triggering drastic geo-political changes as well as generating profound cultural influence across the world. The U.S. launched the war on terror in response and invaded Afghanistan to depose the Taliban and destroy al-Qaeda. In 2003, a U.S.-led coalition invaded Iraq, overthrowing the Ba'athist regime which they falsely accused of having ties with al-Qaeda. In 2004, al-Qaeda launched its Iraqi regional branch. After pursuing him for almost a decade, the U.S. military killed bin Laden in Pakistan in May 2011. + +Al-Qaeda members believe that a Judeo-Christian alliance (led by the United States) is waging a war against Islam and conspiring to destroy Islam. Al-Qaeda also opposes man-made laws, and seek to implement sharīʿah (Islamic law) in Muslim countries. AQ fighters characteristically deploy tactics such as suicide attacks (Inghimasi and Istishhadi operations) involving simultaneous bombing of several targets in battle-zones. Al-Qaeda's Iraq branch, which later morphed into the Islamic State of Iraq after 2006, was responsible for numerous sectarian attacks against Shias during its Iraqi insurgency. Al-Qaeda ideologues envision the violent removal of all foreign and secularist influences in Muslim countries, which it denounces as corrupt deviations. Following the death of bin Laden in 2011, al-Qaeda vowed to avenge his killing. The group was then led by Egyptian Ayman al-Zawahiri until his death in 2022. , they have reportedly suffered from a deterioration of central command over its regional operations. + +Organization +Al-Qaeda only indirectly controls its day-to-day operations. Its philosophy calls for the centralization of decision making, while allowing for the decentralization of execution. The top leaders of Al-Qaeda have defined the organization's ideology and guiding strategy, and they have also articulated simple and easy-to-receive messages. At the same time, mid-level organizations were given autonomy, but they had to consult with top management before large-scale attacks and assassinations. Top management included the shura council as well as committees on military operations, finance, and information sharing. Through the information committees of Al-Qaeda, Zawahiri placed special emphasis on communicating with his groups. However, after the war on terror, Al-Qaeda's leadership has become isolated. As a result, the leadership has become decentralized, and the organization has become regionalized into several Al-Qaeda groups. + +Many Western analysts do not believe that the global jihadist movement is driven at every level by Al-Qaeda's leadership. However, bin Laden held considerable ideological influence over revolutionary Islamist movements across the world. Experts argue that Al-Qaeda has fragmented into a number of disparate regional movements, and that these groups bear little connection with one another. + +This view mirrors the account given by Osama bin Laden in his October 2001 interview with Tayseer Allouni: + + however, Bruce Hoffman saw Al-Qaeda as a cohesive network that was strongly led from the Pakistani tribal areas. + +Affiliates +Al-Qaeda has the following direct affiliates: + + Al-Qaeda in the Arabian Peninsula (AQAP) + Al-Qaeda in the Indian Subcontinent (AQIS) + Al-Qaeda in the Islamic Maghreb (AQIM) + Al Shabaab + Hurras al-Din + Jama'at Nasr al-Islam wal Muslimin (JNIM) + +The following are presently believed to be indirect affiliates of Al-Qaeda: + + Caucasus Emirate (factions) + Fatah al-Islam + Islamic Jihad Union + Islamic Movement of Uzbekistan + Jaish-e-Mohammed + Jemaah Islamiyah + Lashkar-e-Taiba + Moroccan Islamic Combatant Group + +Al-Qaeda's former affiliates include the following: + + Abu Sayyaf (pledged allegiance to ISIL in 2014) + Al-Mourabitoun (joined JNIM in 2017) + Al-Qaeda in Iraq (became the Islamic State of Iraq, which later seceded from al-Qaeda and became ISIL) + Al-Qaeda in the Lands Beyond the Sahel (inactive since 2015) + Ansar al-Islam (majority merged with ISIL in 2014) + Ansar Dine (joined JNIM in 2017) + Islamic Jihad of Yemen (became AQAP) + Movement for Oneness and Jihad in West Africa (merged with Al-Mulathameen to form Al-Mourabitoun in 2013) + Rajah Sulaiman movement + Al-Nusra Front (dissolved in 2017, merged with other Islamist organizations to form Hayat Tahrir al-Sham and split ties) + +Leadership + +Osama bin Laden (1988–May 2011) + +Osama bin Laden served as the emir of Al-Qaeda from the organization's founding in 1988 until his assassination by US forces on May 1, 2011. Atiyah Abd al-Rahman was alleged to be second in command prior to his death on August 22, 2011. + +Bin Laden was advised by a Shura Council, which consists of senior Al-Qaeda members. The group was estimated to consist of 20–30 people. + +After May 2011 +Ayman al-Zawahiri had been Al-Qaeda's deputy emir and assumed the role of emir following bin Laden's death. Al-Zawahiri replaced Saif al-Adel, who had served as interim commander. + +On June 5, 2012, Pakistani intelligence officials announced that al-Rahman's alleged successor as second in command, Abu Yahya al-Libi, had been killed in Pakistan. + +Nasir al-Wuhayshi was alleged to have become Al-Qaeda's overall second in command and general manager in 2013. He was concurrently the leader of Al-Qaeda in the Arabian Peninsula (AQAP) until he was killed by a US airstrike in Yemen in June 2015. Abu Khayr al-Masri, Wuhayshi's alleged successor as the deputy to Ayman al-Zawahiri, was killed by a US airstrike in Syria in February 2017. Al Qaeda's next alleged number two leader, Abdullah Ahmed Abdullah, was killed by Israeli agents. His pseudonym was Abu Muhammad al-Masri, who was killed in November 2020 in Iran. He was involved in the 1998 bombings of the US embassies in Kenya and Tanzania. + +Al-Qaeda's network was built from scratch as a conspiratorial network which drew upon the leadership of a number of regional nodes. The organization divided itself into several committees, which include: + The Military Committee, which is responsible for training operatives, acquiring weapons, and planning attacks. + The Money/Business Committee, which funds the recruitment and training of operatives through the hawala banking system. US-led efforts to eradicate the sources of "terrorist financing" were most successful in the year immediately following the September 11 attacks. Al-Qaeda continues to operate through unregulated banks, such as the 1,000 or so hawaladars in Pakistan, some of which can handle deals of up to million. The committee also procures false passports, pays Al-Qaeda members, and oversees profit-driven businesses. In the 9/11 Commission Report, it was estimated that Al-Qaeda required $30million per year to conduct its operations. + The Law Committee reviews Sharia law, and decides upon courses of action conform to it. + The Islamic Study/Fatwah Committee issues religious edicts, such as an edict in 1998 telling Muslims to kill Americans. + The Media Committee ran the now-defunct newspaper Nashrat al Akhbar () and handled public relations. + In 2005, Al-Qaeda formed As-Sahab, a media production house, to supply its video and audio materials. + +After Al-Zawahiri (2022 - present) +Al-Zawahiri was killed on July 31, 2022 in a drone strike in Afghanistan. In February 2023, a report from the United Nations, based on member state intelligence, concluded that de facto leadership of Al-Qaeda had passed to Saif al-Adel, who was operating out of Iran. Adel, a former Egyptian army officer, became a military instructor in Al-Qaeda camps in the 1990s and was known for his involvement in the Battle of Mogadishu. The report stated that al-Adel's leadership could not officially be declared by al-Qaeda because of "political sensitivities" of Afghan government in acknowledging the death of Al-Zawahiri as well as due to "theological and operational" challenges posed by the location of al-Adel in Iran. + +Command structure +Most of Al Qaeda's top leaders and operational directors were veterans who fought against the Soviet invasion of Afghanistan in the 1980s. Osama bin Laden and his deputy, Ayman al-Zawahiri, were the leaders who were considered the operational commanders of the organization. Nevertheless, Al-Qaeda is not operationally managed by Ayman al-Zawahiri. Several operational groups exist, which consult with the leadership in situations where attacks are in preparation. Al-Qaeda central (AQC) is a conglomerate of expert committees, each in supervision of distinct tasks and objectives. Its membership is mostly composed of Egyptian Islamist leaders who participated in the anti-communist Afghan Jihad. Assisting them are hundreds of Islamic field operatives and commanders, based in various regions of the Muslim World. The central leadership assumes control of the doctrinal approach and overall propaganda campaign; while the regional commanders were empowered with independence in military strategy and political maneuvering. This novel hierarchy made it possible for the organisation to launch wide-range offensives. + +When asked in 2005 about the possibility of Al-Qaeda's connection to the July 7, 2005 London bombings, Metropolitan Police Commissioner Sir Ian Blair said: "Al-Qaeda is not an organization. Al-Qaeda is a way of working... but this has the hallmark of that approach... Al-Qaeda clearly has the ability to provide training... to provide expertise... and I think that is what has occurred here." On August 13, 2005, The Independent newspaper, reported that the July7 bombers had acted independently of an Al-Qaeda mastermind. + +Nasser al-Bahri, who was Osama bin Laden's bodyguard for four years in the run-up to 9/11 wrote in his memoir a highly detailed description of how the group functioned at that time. Al-Bahri described Al-Qaeda's formal administrative structure and vast arsenal. However, the author Adam Curtis argued that the idea of Al-Qaeda as a formal organization is primarily an American invention. Curtis contended the name "Al-Qaeda" was first brought to the attention of the public in the 2001 trial of bin Laden and the four men accused of the 1998 US embassy bombings in East Africa. Curtis wrote: + +During the 2001 trial, the US Department of Justice needed to show that bin Laden was the leader of a criminal organization in order to charge him in absentia under the Racketeer Influenced and Corrupt Organizations Act. The name of the organization and details of its structure were provided in the testimony of Jamal al-Fadl, who said he was a founding member of the group and a former employee of bin Laden. Questions about the reliability of al-Fadl's testimony have been raised by a number of sources because of his history of dishonesty, and because he was delivering it as part of a plea bargain agreement after being convicted of conspiring to attack US military establishments. Sam Schmidt, a defense attorney who defended al-Fadl said: + +Field operatives + +The number of individuals in the group who have undergone proper military training, and are capable of commanding insurgent forces, is largely unknown. Documents captured in the raid on bin Laden's compound in 2011 show that the core Al-Qaeda membership in 2002 was 170. In 2006, it was estimated that Al-Qaeda had several thousand commanders embedded in 40 countries. , it was believed that no more than 200–300 members were still active commanders. + +According to the 2004 BBC documentary The Power of Nightmares, Al-Qaeda was so weakly linked together that it was hard to say it existed apart from bin Laden and a small clique of close associates. The lack of any significant numbers of convicted Al-Qaeda members, despite a large number of arrests on terrorism charges, was cited by the documentary as a reason to doubt whether a widespread entity that met the description of Al-Qaeda existed. Al-Qaeda's commanders, as well as its sleeping agents, are hiding in different parts of the world to this day. They are mainly hunted by the American and Israeli secret services. + +Insurgent forces +According to author Robert Cassidy, Al-Qaeda maintains two separate forces which are deployed alongside insurgents in Iraq and Pakistan. The first, numbering in the tens of thousands, was "organized, trained, and equipped as insurgent combat forces" in the Soviet–Afghan war. The force was composed primarily of foreign mujahideen from Saudi Arabia and Yemen. Many of these fighters went on to fight in Bosnia and Somalia for global jihad. Another group, which numbered 10,000 in 2006, live in the West and have received rudimentary combat training. + +Other analysts have described Al-Qaeda's rank and file as being "predominantly Arab" in its first years of operation, but that the organization also includes "other peoples" . It has been estimated that 62 percent of Al-Qaeda members have a university education. In 2011 and the following year, the Americans successfully settled accounts with Osama bin Laden, Anwar al-Awlaki, the organization's chief propagandist, and Abu Yahya al-Libi's deputy commander. The optimistic voices were already saying it was over for Al-Qaeda. Nevertheless, it was around this time that the Arab Spring greeted the region, the turmoil of which came great to Al-Qaeda's regional forces. Seven years later, Ayman al-Zawahiri became arguably the number one leader in the organization, implementing his strategy with systematic consistency. Tens of thousands loyal to Al-Qaeda and related organizations were able to challenge local and regional stability and ruthlessly attack their enemies in the Middle East, Africa, South Asia, Southeast Asia, Europe and Russia alike. In fact, from Northwest Africa to South Asia, Al-Qaeda had more than two dozen "franchise-based" allies. The number of Al-Qaeda militants was set at 20,000 in Syria alone, and they had 4,000 members in Yemen and about 7,000 in Somalia. The war was not over. + +In 2001, Al-Qaeda had around 20 functioning cells and 70,000 insurgents spread over sixty nations. According to latest estimates, the number of active-duty soldiers under its command and allied militias have risen to approximately 250,000 by 2018. + +Financing + +Al-Qaeda usually does not disburse funds for attacks, and very rarely makes wire transfers. In the 1990s, financing came partly from the personal wealth of Osama bin Laden. Other sources of income included the heroin trade and donations from supporters in Kuwait, Saudi Arabia and other Islamic Gulf states. A WikiLeaks-released 2009 internal US government cable stated that "terrorist funding emanating from Saudi Arabia remains a serious concern." + +Among the first pieces of evidence regarding Saudi Arabia's support for Al-Qaeda was the so-called "Golden Chain", a list of early Al-Qaeda funders seized during a 2002 raid in Sarajevo by Bosnian police. The hand-written list was validated by Al-Qaeda defector Jamal al-Fadl, and included the names of both donors and beneficiaries. Osama bin-Laden's name appeared seven times among the beneficiaries, while 20 Saudi and Gulf-based businessmen and politicians were listed among the donors. Notable donors included Adel Batterjee, and Wael Hamza Julaidan. Batterjee was designated as a terror financier by the US Department of the Treasury in 2004, and Julaidan is recognized as one of Al-Qaeda's founders. + +Documents seized during the 2002 Bosnia raid showed that Al-Qaeda widely exploited charities to channel financial and material support to its operatives across the globe. Notably, this activity exploited the International Islamic Relief Organization (IIRO) and the Muslim World League (MWL). The IIRO had ties with Al-Qaeda associates worldwide, including Al-Qaeda's deputy Ayman al Zawahiri. Zawahiri's brother worked for the IIRO in Albania and had actively recruited on behalf of Al-Qaeda. The MWL was openly identified by Al-Qaeda's leader as one of the three charities Al-Qaeda primarily relied upon for funding sources. + +Allegations of Qatari support + +Several Qatari citizens have been accused of funding Al-Qaeda. This includes Abd Al-Rahman al-Nuaimi, a Qatari citizen and a human-rights activist who founded the Swiss-based non-governmental organization (NGO) Alkarama. On December 18, 2013, the US Treasury designated Nuaimi as a terrorist for his activities supporting Al-Qaeda. The US Treasury has said Nuaimi "has facilitated significant financial support to Al-Qaeda in Iraq, and served as an interlocutor between Al-Qaeda in Iraq and Qatar-based donors". + +Nuaimi was accused of overseeing a $2million monthly transfer to Al-Qaeda in Iraq as part of his role as mediator between Iraq-based Al-Qaeda senior officers and Qatari citizens. Nuaimi allegedly entertained relationships with Abu-Khalid al-Suri, Al-Qaeda's top envoy in Syria, who processed a $600,000 transfer to Al-Qaeda in 2013. Nuaimi is also known to be associated with Abd al-Wahhab Muhammad 'Abd al-Rahman al-Humayqani, a Yemeni politician and founding member of Alkarama, who was listed as a Specially Designated Global Terrorist (SDGT) by the US Treasury in 2013. The US authorities claimed that Humayqani exploited his role in Alkarama to fundraise on behalf of Al-Qaeda in the Arabian Peninsula (AQAP). A prominent figure in AQAP, Nuaimi was also reported to have facilitated the flow of funding to AQAP affiliates based in Yemen. Nuaimi was also accused of investing funds in the charity directed by Humayqani to ultimately fund AQAP. About ten months after being sanctioned by the US Treasury, Nuaimi was also restrained from doing business in the UK. + +Another Qatari citizen, Kalifa Mohammed Turki Subayi, was sanctioned by the US Treasury on June 5, 2008, for his activities as a "Gulf-based Al-Qaeda financier". Subayi's name was added to the UN Security Council's Sanctions List in 2008 on charges of providing financial and material support to Al-Qaeda senior leadership. Subayi allegedly moved Al-Qaeda recruits to South Asia-based training camps. He also financially supported Khalid Sheikh Mohammed, a Pakistani national and senior Al-Qaeda officer who is believed to be the mastermind behind the September 11 attack according to the 9/11 Commission Report. + +Qataris provided support to al-Qaeda through the country's largest NGO, the Qatar Charity. Al-Qaeda defector al-Fadl, who was a former member of Qatar Charity, testified in court that Abdullah Mohammed Yusef, who served as Qatar Charity's director, was affiliated to Al-Qaeda and simultaneously to the National Islamic Front, a political group that gave al-Qaeda leader Osama Bin Laden harbor in Sudan in the early 1990s. + +It was alleged that in 1993 Osama bin Laden was using Middle East based Sunni charities to channel financial support to Al-Qaeda operatives overseas. The same documents also report Bin Laden's complaint that the failed assassination attempt of Egyptian President Hosni Mubarak had compromised the ability of Al-Qaeda to exploit charities to support its operatives to the extent it was capable of before 1995. + +Qatar financed Al-Qaeda's enterprises through Al-Qaeda's former affiliate in Syria, Jabhat al-Nusra. The funding was primarily channeled through kidnapping for ransom. The Consortium Against Terrorist Finance (CATF) reported that the Gulf country has funded al-Nusra since 2013. In 2017, Asharq Al-Awsat estimated that Qatar had disbursed $25million in support of al-Nusra through kidnapping for ransom. In addition, Qatar has launched fundraising campaigns on behalf of al-Nusra. Al-Nusra acknowledged a Qatar-sponsored campaign "as one of the preferred conduits for donations intended for the group". + +Strategy + +In the disagreement over whether Al-Qaeda's objectives are religious or political, Mark Sedgwick describes Al-Qaeda's strategy as political in the immediate term but with ultimate aims that are religious. +On March 11, 2005, Al-Quds Al-Arabi published extracts from Saif al-Adel's document "Al Qaeda's Strategy to the Year 2020". Abdel Bari Atwan summarizes this strategy as comprising five stages to rid the Ummah from all forms of oppression: + Provoke the United States and the West into invading a Muslim country by staging a massive attack or string of attacks on US soil that results in massive civilian casualties. + Incite local resistance to occupying forces. + Expand the conflict to neighboring countries and engage the US and its allies in a long war of attrition. + Convert Al-Qaeda into an ideology and set of operating principles that can be loosely franchised in other countries without requiring direct command and control, and via these franchises incite attacks against the US and countries allied with the US until they withdraw from the conflict, as happened with the 2004 Madrid train bombings, but which did not have the same effect with the July 7, 2005 London bombings. + The US economy will finally collapse by 2020, under the strain of multiple engagements in numerous places. This will lead to a collapse in the worldwide economic system, and lead to global political instability. This will lead to a global jihad led by Al-Qaeda, and a Wahhabi Caliphate will then be installed across the world. + +Atwan noted that, while the plan is unrealistic, "it is sobering to consider that this virtually describes the downfall of the Soviet Union." + +According to Fouad Hussein, a Jordanian journalist and author who has spent time in prison with Al-Zarqawi, Al-Qaeda's strategy consists of seven phases and is similar to the plan described in Al Qaeda's Strategy to the year 2020. These phases include: + "The Awakening." This phase was supposed to last from 2001 to 2003. The goal of the phase is to provoke the United States to attack a Muslim country by executing an attack that kills many civilians on US soil. + "Opening Eyes." This phase was supposed to last from 2003 to 2006. The goal of this phase was to recruit young men to the cause and to transform the Al-Qaeda group into a movement. Iraq was supposed to become the center of all operations with financial and military support for bases in other states. + "Arising and Standing up", was supposed to last from 2007 to 2010. In this phase, Al-Qaeda wanted to execute additional attacks and focus their attention on Syria. Hussein believed other countries in the Arabian Peninsula were also in danger. + Al-Qaeda expected a steady growth among their ranks and territories due to the declining power of the regimes in the Arabian Peninsula. The main focus of attack in this phase was supposed to be on oil suppliers and cyberterrorism, targeting the US economy and military infrastructure. + The declaration of an Islamic Caliphate, which was projected between 2013 and 2016. In this phase, Al-Qaeda expected the resistance from Israel to be heavily reduced. + The declaration of an "Islamic Army" and a "fight between believers and non-believers", also called "total confrontation". + "Definitive Victory", projected to be completed by 2020. + +According to the seven-phase strategy, the war is projected to last less than two years. + +According to Charles Lister of the Middle East Institute and Katherine Zimmerman of the American Enterprise Institute, the new model of Al-Qaeda is to "socialize communities" and build a broad territorial base of operations with the support of local communities, also gaining income independent of the funding of sheiks. + +Name +The English name of the organization is a simplified transliteration of the Arabic noun (), which means "the foundation" or "the base". The initial al- is the Arabic definite article "the", hence "the base". In Arabic, Al-Qaeda has four syllables (). However, since two of the Arabic consonants in the name are not phones found in the English language, the common naturalized English pronunciations include , and . Al-Qaeda's name can also be transliterated as al-Qaida, al-Qa'ida, or el-Qaida. + +The doctrinal concept of "Al-Qaeda" was first coined by the Palestinian Islamist scholar and Jihadist leader Abdullah Azzam in an April 1988 issue of Al-Jihad magazine to describe a religiously committed vanguard of Muslims who wage armed Jihad globally to liberate oppressed Muslims from foreign invaders, establish sharia (Islamic law) across the Islamic World by overthrowing the ruling secular governments; and thus restore the past Islamic prowess. This was to be implemented by establishing an Islamic state that would nurture generations of Muslim soldiers that would perpetually attack United States and its allied governments in the Muslim World. Numerous historical models were cited by Azzam as successful examples of his call; starting from the early Muslim conquests of the 7th century to the recent anti-Soviet Afghan Jihad of 1980s. According to Azzam's world-view: It is about time to think about a state that would be a solid base for the distribution of the (Islamic) creed, and a fortress to host the preachers from the hell of the Jahiliyyah [the pre-Islamic period]. + +Bin Laden explained the origin of the term in a videotaped interview with Al Jazeera journalist Tayseer Alouni in October 2001: + +It has been argued that two documents seized from the Sarajevo office of the Benevolence International Foundation prove the name was not simply adopted by the mujahideen movement and that a group called Al-Qaeda was established in August 1988. Both of these documents contain minutes of meetings held to establish a new military group, and contain the term "Al-Qaeda". + +Former British Foreign Secretary Robin Cook wrote that the word Al-Qaeda should be translated as "the database", because it originally referred to the computer file of the thousands of mujahideen militants who were recruited and trained with CIA help to defeat the Russians. In April 2002, the group assumed the name Qa'idat al-Jihad ( ), which means "the base of Jihad". According to Diaa Rashwan, this was "apparently as a result of the merger of the overseas branch of Egypt's al-Jihad, which was led by Ayman al-Zawahiri, with the groups Bin Laden brought under his control after his return to Afghanistan in the mid-1990s." + +Ideology + +The militant Islamist Salafist movement of Al-Qaeda developed during the Islamic revival and the rise of the Islamist movement after the Iranian Revolution (1978–1979) and the Afghan Jihad (1979–1989). Many scholars have argued that the writings of Islamic author and thinker Sayyid Qutb inspired the Al-Qaeda organization. In the 1950s and 1960s, Qutb preached that because of the lack of sharia law, the Muslim world was no longer Muslim, and had reverted to the pre-Islamic ignorance known as jahiliyyah. To restore Islam, Qutb argued that a vanguard of righteous Muslims was needed in order to establish "true Islamic states", implement sharia, and rid the Muslim world of any non-Muslim influences. In Qutb's view, the enemies of Islam included "world Jewry", which "plotted conspiracies" and opposed Islam. Qutb envisioned this vanguard to march forward to wage armed Jihad against tyrannical regimes after purifying from the wider Jahili societies and organising themselves under a righteous Islamic leadership; which he viewed as the model of early Muslims in the Islamic state of Medina under the leadership of Islamic Prophet Muhammad. This idea would directly influence many Islamist figures such as Abdullah Azzam and Usama Bin Laden; and became the core rationale for the formulation of "Al-Qaeda" concept in the near future. Outlining his strategy to topple the existing secular orders, Qutb argued in Milestones: [It is necessary that] a Muslim community to come into existence which believes that ‘there is no deity except God,’ which commits itself to obey none but God, denying all other authority, and which challenges the legality of any law which is not based on this belief.. . It should come into the battlefield with the determination that its strategy, its social organization, and the relationship between its individuals should be firmer and more powerful than the existing jahili system. +In the words of Mohammed Jamal Khalifa, a close college friend of bin Laden: + +Qutb also influenced Ayman al-Zawahiri. Zawahiri's uncle and maternal family patriarch, Mafouz Azzam, was Qutb's student, protégé, personal lawyer, and an executor of his estate. Azzam was one of the last people to see Qutb alive before his execution. Zawahiri paid homage to Qutb in his work Knights under the Prophet's Banner. + +Qutb argued that many Muslims were not true Muslims. Some Muslims, Qutb argued, were apostates. These alleged apostates included leaders of Muslim countries, since they failed to enforce sharia law. He also alleged that the West approaches the Muslim World with a "crusading spirit"; in spite of the decline of religious values in the 20th century Europe. According to Qutb; the hostile and imperialist attitudes exhibited by Europeans and Americans towards Muslim countries, their support for Zionism, etc. reflected hatred amplified over a millennia of wars such as the Crusades and was born out of Roman materialist and utilitarian outlooks that viewed the world in monetary terms. + +Formation + +The Afghan jihad against the pro-Soviet government further developed the Salafist Jihadist movement which inspired Al-Qaeda. During this period, Al-Qaeda embraced the ideals of the South Asian militant revivalist Sayyid Ahmad Shahid (d. 1831/1246 A.H) who led a Jihad movement against British India from the frontiers of Afghanistan and Khyber-Pakhtunkwa in the early 19th century. Al-Qaeda readily adopted Sayyid Ahmad's doctrines such as returning to the purity of early generations (Salaf as-Salih), antipathy towards Western influences and restoration of Islamic political power. According to Pakistani journalist Hussain Haqqani, + +Objectives +The long-term objective of Al-Qaeda is to unite the Muslim World under a supra-national Islamic state known as the Khilafah (Caliphate), headed by an elected Caliph descended from the Ahl al-Bayt (Prophetic family). The immediate objectives include the expulsion of American troops from the Arabian Peninsula, waging armed Jihad to topple US-allied governments in the region, etc. + +The following are the goals and some of the general policies outlined in Al-Qaeda's Founding Charter "Al-Qaeda's Structure and Bylaws" issued in the meetings in Peshawar in 1988.: + +Theory of Islamic State + +Al-Qaeda aims to establish an Islamic state in the Arab World, modelled after the Rashidun Caliphate, by initiating a global Jihad against the "International Jewish-Crusader Alliance" led by the United States, which it sees as the "external enemy" and against the secular governments in Muslim countries, that are described as "the apostate domestic enemy". Once foreign influences and the secular ruling authorities are removed from Muslim countries through Jihad; al-Qaeda supports elections to choose the rulers of its proposed Islamic states. This is to be done through representatives of leadership councils (Shura) that would ensure the implementation of Shari'a (Islamic law). However, it opposes elections that institute parliaments which empower Muslim and non-Muslim legislators to collaborate in making laws of their own choosing. In the second edition of his book Knights Under the Banner of the Prophet, Ayman Al Zawahiri writes: + +Grievances +A recurring theme in al-Qaeda's ideology is the perpetual grievance over the violent subjugation of Islamic dissidents by the authoritarian, secularist regimes allied to the West. Al-Qaeda denounces these post-colonial governments as a system led by Westernised elites designed to advance neo-colonialism and maintain Western hegemony over the Muslim World. The most prominent topic of grievance is over the American foreign policy in the Arab World; especially over its strong economic and military support to Israel. Other concerns of resentment include presence of NATO troops to support allied regimes; injustices committed against Muslims in Kashmir, Chechnya, Xinjiang, Syria, Afghanistan, Iraq etc. + +Religious compatibility +Abdel Bari Atwan wrote that: +On the other hand, Professor Peter Mandaville states that Al-Qaeda follows a pragmatic policy in forming its local affiliates, with various cells being sub-contracted to Shia Muslim and non-Muslim members. The top-down chain of command means that each unit is answerable directly to central leadership, while they remain ignorant of their counterparts' presence or activities. These transnational networks of autonomous supply chains, financiers, underground militias and political supporters were set up during the 1990s, when Bin Laden's immediate aim was the expulsion of American troops from the Arabian Peninsula. + +Attacks on civilians +Under the leadership of Osama Bin Laden and Ayman al-Zawahiri, Al-Qaeda organization adopted the strategy of targeting non-combatant civilians of enemy states that indiscriminately attacked Muslims. Following the September 11 attacks, al-Qaeda provided a justification for the killing of non-combatants/civilians, entitled, "A Statement from Qaidat al-Jihad Regarding the Mandates of the Heroes and the Legality of the Operations in New York and Washington". According to a couple of critics, Quintan Wiktorowicz and John Kaltner, it provides "ample theological justification for killing civilians in almost any imaginable situation." + +Among these justifications are that America is leading the west in waging a War on Islam so that attacks on America are a defense of Islam and any treaties and agreements between Muslim majority states and Western countries that would be violated by attacks are null and void. According to the tract, several conditions allow for the killing of civilians including: + retaliation for the American war on Islam which al-Qaeda alleges has targeted "Muslim women, children and elderly"; + when it is too difficult to distinguish between non-combatants and combatants when attacking an enemy "stronghold" (hist) and/or non-combatants remain in enemy territory, killing them is allowed; + those who assist the enemy "in deed, word, mind" are eligible for killing, and this includes the general population in democratic countries because civilians can vote in elections that bring enemies of Islam to power; + the necessity of killing in the war to protect Islam and Muslims; + the prophet Muhammad, when asked whether the Muslim fighters could use the catapult against the village of Taif, replied affirmatively, even though the enemy fighters were mixed with a civilian population; + if the women, children and other protected groups serve as human shields for the enemy; + if the enemy has broken a treaty, killing of civilians is permitted. +Under the leadership of Sayf al-Adel, Al-Qaeda's strategy has underwent transformation and the organization has officially renounced the tactic of attacking civilian targets of enemies. In his book "Free Reading of 33 Strategies of War" published in 2023, Sayf al-Adel counselled Islamist fighters to prioritize attacking the police forces, military soldiers, state assets of enemy governments, etc. which he described as acceptable targets in military operations. Asserting that attacking women and children of enemies are contrary to Islamic values, Sayf al-Adel asked: "If we target the general public, how can we expect their people to accept our call to Islam?" + +History + +Attacks + +Al-Qaeda has carried out a total of six major attacks, four of them in its jihad against America. In each case the leadership planned the attack years in advance, arranging for the shipment of weapons and explosives and using its businesses to provide operatives with safehouses and false identities. + +1991 +To prevent the former Afghan king Mohammed Zahir Shah from coming back from exile and possibly becoming head of a new government, bin Laden instructed a Portuguese convert to Islam, Paulo Jose de Almeida Santos, to assassinate Zahir Shah. On November 4, 1991, Santos entered the king's villa in Rome posing as a journalist and tried to stab him with a dagger. A tin of cigarillos in the king's breast pocket deflected the blade and saved Zahir Shah's life. Santos was apprehended and jailed for 10 years in Italy. + +1992 +On December 29, 1992, Al-Qaeda launched the 1992 Yemen hotel bombings. Two bombs were detonated in Aden, Yemen. The first target was the Movenpick Hotel and the second was the parking lot of the Goldmohur Hotel. + +The bombings were an attempt to eliminate American soldiers on their way to Somalia to take part in the international famine relief effort, Operation Restore Hope. Internally, Al-Qaeda considered the bombing a victory that frightened the Americans away, but in the US, the attack was barely noticed. No American soldiers were killed because no soldiers were staying in the hotel at the time it was bombed, however, an Australian tourist and a Yemeni hotel worker were killed in the bombing. Seven others, who were mostly Yemeni, were severely injured. Two fatwas are said to have been appointed by Al-Qaeda's members, Mamdouh Mahmud Salim, to justify the killings according to Islamic law. Salim referred to a famous fatwa appointed by Ibn Taymiyyah, a 13th-century scholar admired by Wahhabis, which sanctioned resistance by any means during the Mongol invasions. + +Late 1990s + +In 1996, bin Laden personally engineered a plot to assassinate United States President Bill Clinton while the president was in Manila for the Asia-Pacific Economic Cooperation. However, intelligence agents intercepted a message before the motorcade was to leave, and alerted the US Secret Service. Agents later discovered a bomb planted under a bridge. + +On August 7, 1998, Al-Qaeda bombed the US embassies in East Africa, killing 224 people, including 12 Americans. In retaliation, a barrage of cruise missiles launched by the US military devastated an Al-Qaeda base in Khost, Afghanistan. The network's capacity was unharmed. In late 1999 and 2000, Al-Qaeda planned attacks to coincide with the millennium, masterminded by Abu Zubaydah and involving Abu Qatada, which would include the bombing of Christian holy sites in Jordan, the bombing of Los Angeles International Airport by Ahmed Ressam, and the bombing of the . + +On October 12, 2000, Al-Qaeda militants in Yemen bombed the missile destroyer USS Cole in a suicide attack, killing 17 US servicemen and damaging the vessel while it lay offshore. Inspired by the success of such a brazen attack, Al-Qaeda's command core began to prepare for an attack on the US itself. + +September 11 attacks + +The September 11 attacks on America by Al-Qaeda killed 2,996 people2,507 civilians, 343 firefighters, 72 law enforcement officers, 55 military personnel as well as 19 hijackers who committed murder-suicide. Two commercial airliners were deliberately flown into the twin towers of the World Trade Center, a third into the Pentagon, and a fourth, originally intended to target either the United States Capitol or the White House, crashed in a field in Stonycreek Township near Shanksville, Pennsylvania after passengers revolted. It was the deadliest foreign attack on American soil since the Japanese attack on Pearl Harbor on December 7, 1941, and to this day remains the deadliest terrorist attack in human history. + +The attacks were conducted by Al-Qaeda, acting in accord with the 1998 fatwa issued against the US and its allies by persons under the command of bin Laden, al-Zawahiri, and others. Evidence points to suicide squads led by Al-Qaeda military commander Mohamed Atta as the culprits of the attacks, with bin Laden, Ayman al-Zawahiri, Khalid Sheikh Mohammed, and Hambali as the key planners and part of the political and military command. + +Messages issued by bin Laden after September 11, 2001, praised the attacks, and explained their motivation while denying any involvement. Bin Laden legitimized the attacks by identifying grievances felt by both mainstream and Islamist Muslims, such as the general perception that the US was actively oppressing Muslims. + +Bin Laden asserted that America was massacring Muslims in "Palestine, Chechnya, Kashmir and Iraq" and Muslims should retain the "right to attack in reprisal". He also claimed the 9/11 attacks were not targeted at people, but "America's icons of military and economic power", despite the fact he planned to attack in the morning when most of the people in the intended targets were present and thus generating the maximum number of human casualties. + +Evidence later came to light that the original targets for the attack may have been nuclear power stations on the US East Coast. The targets were later altered by Al-Qaeda, as it was feared that such an attack "might get out of hand". + +Designation as a terrorist group +Al-Qaeda is deemed a designated terrorist group by the following countries and international organizations: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + designated Al-Qaeda's Turkish branch + + + United Nations Security Council + +War on terror + +In the immediate aftermath of the 9/11 attacks, the US government responded, and began to prepare its armed forces to overthrow the Taliban, which it believed was harboring Al-Qaeda. The US offered Taliban leader Mullah Omar a chance to surrender bin Laden and his top associates. The first forces to be inserted into Afghanistan were paramilitary officers from the CIA's elite Special Activities Division (SAD). + +The Taliban offered to turn over bin Laden to a neutral country for trial if the US would provide evidence of bin Laden's complicity in the attacks. US President George W. Bush responded by saying: "We know he's guilty. Turn him over", and British Prime Minister Tony Blair warned the Taliban regime: "Surrender bin Laden, or surrender power." + +Soon thereafter the US and its allies invaded Afghanistan, and together with the Afghan Northern Alliance removed the Taliban government as part of the war in Afghanistan. As a result of the US special forces and air support for the Northern Alliance ground forces, a number of Taliban and Al-Qaeda training camps were destroyed, and much of the operating structure of Al-Qaeda is believed to have been disrupted. After being driven from their key positions in the Tora Bora area of Afghanistan, many Al-Qaeda fighters tried to regroup in the rugged Gardez region of the nation. + +By early 2002, Al-Qaeda had been dealt a serious blow to its operational capacity, and the Afghan invasion appeared to be a success. Nevertheless, a significant Taliban insurgency remained in Afghanistan. + +Debate continued regarding the nature of Al-Qaeda's role in the 9/11 attacks. The US State Department released a videotape showing bin Laden speaking with a small group of associates somewhere in Afghanistan shortly before the Taliban was removed from power. Although its authenticity has been questioned by a couple of people, the tape definitively implicates bin Laden and Al-Qaeda in the September 11 attacks. The tape was aired on many television channels, with an accompanying English translation provided by the US Defense Department. + +In September 2004, the 9/11 Commission officially concluded that the attacks were conceived and implemented by al-Qaeda operatives. In October 2004, bin Laden appeared to claim responsibility for the attacks in a videotape released through Al Jazeera, saying he was inspired by Israeli attacks on high-rises in the 1982 invasion of Lebanon: "As I looked at those demolished towers in Lebanon, it entered my mind that we should punish the oppressor in kind and that we should destroy towers in America in order that they taste some of what we tasted and so that they be deterred from killing our women and children." + +By the end of 2004, the US government proclaimed that two-thirds of the most senior Al-Qaeda figures from 2001 had been captured and interrogated by the CIA: Abu Zubaydah, Ramzi bin al-Shibh and Abd al-Rahim al-Nashiri in 2002; Khalid Sheikh Mohammed in 2003; and Saif al Islam el Masry in 2004. Mohammed Atef and several others were killed. The West was criticized for not being able to handle Al-Qaida despite a decade of the war. + +Activities + +Africa + +Al-Qaeda involvement in Africa has included a number of bombing attacks in North Africa, while supporting parties in civil wars in Eritrea and Somalia. From 1991 to 1996, bin Laden and other Al-Qaeda leaders were based in Sudan. + +Islamist rebels in the Sahara calling themselves Al-Qaeda in the Islamic Maghreb have stepped up their violence in recent years. French officials say the rebels have no real links to the Al-Qaeda leadership, but this has been disputed. It seems likely that bin Laden approved the group's name in late 2006, and the rebels "took on the al Qaeda franchise label", almost a year before the violence began to escalate. + +In Mali, the Ansar Dine faction was also reported as an ally of Al-Qaeda in 2013. The Ansar al Dine faction aligned themselves with the AQIM. + +In 2011, Al-Qaeda's North African wing condemned Libyan leader Muammar Gaddafi and declared support for the Anti-Gaddafi rebels. + +Following the Libyan Civil War, the removal of Gaddafi and the ensuing period of post-civil war violence in Libya, various Islamist militant groups affiliated with Al-Qaeda were able to expand their operations in the region. The 2012 Benghazi attack, which resulted in the death of US Ambassador J. Christopher Stevens and three other Americans, is suspected of having been carried out by various Jihadist networks, such as Al-Qaeda in the Islamic Maghreb, Ansar al-Sharia and several other Al-Qaeda affiliated groups. The capture of Nazih Abdul-Hamed al-Ruqai, a senior Al-Qaeda operative wanted by the United States for his involvement in the 1998 United States embassy bombings, on October 5, 2013, by US Navy Seals, FBI and CIA agents illustrates the importance the US and other Western allies have placed on North Africa. + +Europe + +Prior to the September 11 attacks, Al-Qaeda was present in Bosnia and Herzegovina, and its members were mostly veterans of the El Mudžahid detachment of the Bosnian Muslim Army of the Republic of Bosnia and Herzegovina. Three Al-Qaeda operatives carried out the Mostar car bombing in 1997. The operatives were closely linked to and financed by the Saudi High Commission for Relief of Bosnia and Herzegovina founded by then-prince King Salman of Saudi Arabia. + +Before the 9/11 attacks and the US invasion of Afghanistan, westerners who had been recruits at Al-Qaeda training camps were sought after by Al-Qaeda's military wing. Language skills and knowledge of Western culture were generally found among recruits from Europe, such was the case with Mohamed Atta, an Egyptian national studying in Germany at the time of his training, and other members of the Hamburg Cell. Osama bin Laden and Mohammed Atef would later designate Atta as the ringleader of the 9/11 hijackers. Following the attacks, Western intelligence agencies determined that Al-Qaeda cells operating in Europe had aided the hijackers with financing and communications with the central leadership based in Afghanistan. + +In 2003, Islamists carried out a series of bombings in Istanbul killing fifty-seven people and injuring seven hundred. Seventy-four people were charged by the Turkish authorities. Some had previously met bin Laden, and though they specifically declined to pledge allegiance to Al-Qaeda they asked for its blessing and help. + +In 2009, three Londoners, Tanvir Hussain, Assad Sarwar and Ahmed Abdullah Ali, were convicted of conspiring to detonate bombs disguised as soft drinks on seven airplanes bound for Canada and the US The MI5 investigation regarding the plot involved more than a year of surveillance work conducted by over two hundred officers. British and US officials said the plotunlike many similar homegrown European Islamic militant plotswas directly linked to Al-Qaeda and guided by senior Al-Qaeda members in Pakistan. + +In 2012, Russian Intelligence indicated that Al-Qaeda had given a call for "forest jihad" and has been starting massive forest fires as part of a strategy of "thousand cuts". + +Arab world + +Following Yemeni unification in 1990, Wahhabi networks began moving missionaries into the country. Although it is unlikely bin Laden or Saudi Al-Qaeda were directly involved, the personal connections they made would be established over the next decade and used in the USS Cole bombing. Concerns grew over al-Qaeda's group in Yemen. + +In Iraq, al-Qaeda forces loosely associated with the leadership were embedded in the Jama'at al-Tawhid wal-Jihad group commanded by Abu Musab al-Zarqawi. Specializing in suicide operations, they have been a "key driver" of the Sunni insurgency. Although they played a small part in the overall insurgency, between 30% and 42% of all suicide bombings which took place in the early years were claimed by Zarqawi's group. Reports have indicated that oversights such as the failure to control access to the Qa'qaa munitions factory in Yusufiyah have allowed large quantities of munitions to fall into the hands of al-Qaida. In November 2010, the militant group Islamic State of Iraq, which is linked to al-Qaeda in Iraq, threatened to "exterminate all Iraqi Christians". + +Al-Qaeda did not begin training Palestinians until the late 1990s. Large groups such as Hamas and Palestinian Islamic Jihad have rejected an alliance with al-Qaeda, fearing that al-Qaeda will co-opt their cells. This may have changed recently. The Israeli security and intelligence services believe al-Qaeda has managed to infiltrate operatives from the Occupied Territories into Israel, and is waiting for an opportunity to attack. + +, Saudi Arabia, Qatar and Turkey are openly supporting the Army of Conquest, an umbrella rebel group fighting in the Syrian Civil War against the Syrian government that reportedly includes an al-Qaeda linked al-Nusra Front and another Salafi coalition known as Ahrar al-Sham. + +Kashmir + +Bin Laden and Ayman al-Zawahiri consider India to be a part of an alleged Crusader-Zionist-Hindu conspiracy against the Islamic world. According to a 2005 report by the Congressional Research Service, bin Laden was involved in training militants for Jihad in Kashmir while living in Sudan in the early 1990s. By 2001, Kashmiri militant group Harkat-ul-Mujahideen had become a part of the al-Qaeda coalition. According to the United Nations High Commissioner for Refugees (UNHCR), al-Qaeda was thought to have established bases in Pakistan administered Kashmir (in Azad Kashmir, and to some extent in Gilgit–Baltistan) during the 1999 Kargil War and continued to operate there with tacit approval of Pakistan's Intelligence services. + +Many of the militants active in Kashmir were trained in the same madrasahs as Taliban and Al-Qaeda. Fazlur Rehman Khalil of Kashmiri militant group Harkat-ul-Mujahideen was a signatory of al-Qaeda's 1998 declaration of Jihad against America and its allies. In a 'Letter to American People' (2002), bin Laden wrote that one of the reasons he was fighting America was because of its support to India on the Kashmir issue. In November 2001, Kathmandu airport went on high alert after threats that bin Laden planned to hijack a plane and crash it into a target in New Delhi. In 2002, US Secretary of Defense Donald Rumsfeld, on a trip to Delhi, suggested that Al-Qaeda was active in Kashmir though he did not have any evidence. Rumsfeld proposed hi-tech ground sensors along the Line of Control to prevent militants from infiltrating into Indian-administered Kashmir. +An investigation in 2002 found evidence that al-Qaeda and its affiliates were prospering in Pakistan-administered Kashmir with tacit approval of Pakistan's Inter-Services Intelligence. In 2002, a special team of Special Air Service and Delta Force was sent into Indian-Administered Kashmir to hunt for bin Laden after receiving reports that he was being sheltered by Kashmiri militant group Harkat-ul-Mujahideen, which had been responsible for kidnapping western tourists in Kashmir in 1995. Britain's highest-ranking al-Qaeda operative Rangzieb Ahmed had previously fought in Kashmir with the group Harkat-ul-Mujahideen and spent time in Indian prison after being captured in Kashmir. + +US officials believe al-Qaeda was helping organize attacks in Kashmir in order to provoke conflict between India and Pakistan. Their strategy was to force Pakistan to move its troops to the border with India, thereby relieving pressure on al-Qaeda elements hiding in northwestern Pakistan. In 2006 al-Qaeda claimed they had established a wing in Kashmir. However Indian Army General H. S. Panag argued that the army had ruled out the presence of al-Qaeda in Indian-administered Jammu and Kashmir. Panag also said al-Qaeda had strong ties with Kashmiri militant groups Lashkar-e-Taiba and Jaish-e-Mohammed based in Pakistan. It has been noted that Waziristan has become a battlefield for Kashmiri militants fighting NATO in support of al-Qaeda and Taliban. Dhiren Barot, who wrote the Army of Madinah in Kashmir and was an al-Qaeda operative convicted for involvement in the 2004 financial buildings plot, had received training in weapons and explosives at a militant training camp in Kashmir. + +Maulana Masood Azhar, the founder of Kashmiri group Jaish-e-Mohammed, is believed to have met bin Laden several times and received funding from him. In 2002, Jaish-e-Mohammed organized the kidnapping and murder of Daniel Pearl in an operation run in conjunction with al-Qaeda and funded by bin Laden. According to American counter-terrorism expert Bruce Riedel, al-Qaeda and Taliban were closely involved in the 1999 hijacking of Indian Airlines Flight 814 to Kandahar which led to the release of Maulana Masood Azhar and Ahmed Omar Saeed Sheikh from an Indian prison. This hijacking, Riedel said, was rightly described by then Indian Foreign Minister Jaswant Singh as a 'dress rehearsal' for September 11 attacks. Bin Laden personally welcomed Azhar and threw a lavish party in his honor after his release. Ahmed Omar Saeed Sheikh, who had been in prison for his role in the 1994 kidnappings of Western tourists in India, went on to murder Daniel Pearl and was sentenced to death in Pakistan. Al-Qaeda operative Rashid Rauf, who was one of the accused in 2006 transatlantic aircraft plot, was related to Maulana Masood Azhar by marriage. + +Lashkar-e-Taiba, a Kashmiri militant group which is thought to be behind 2008 Mumbai attacks, is also known to have strong ties to senior al-Qaeda leaders living in Pakistan. In late 2002, top Al-Qaeda operative Abu Zubaydah was arrested while being sheltered by Lashkar-e-Taiba in a safe house in Faisalabad. The FBI believes al-Qaeda and Lashkar have been 'intertwined' for a long time while the CIA has said that al-Qaeda funds Lashkar-e-Taiba. Jean-Louis Bruguière told Reuters in 2009 that "Lashkar-e-Taiba is no longer a Pakistani movement with only a Kashmir political or military agenda. Lashkar-e-Taiba is a member of al-Qaeda." + +In a video released in 2008, American-born senior al-Qaeda operative Adam Yahiye Gadahn said that "victory in Kashmir has been delayed for years; it is the liberation of the jihad there from this interference which, Allah willing, will be the first step towards victory over the Hindu occupiers of that Islam land." + +In September 2009, a US drone strike reportedly killed Ilyas Kashmiri who was the chief of Harkat-ul-Jihad al-Islami, a Kashmiri militant group associated with al-Qaeda. Kashmiri was described by Bruce Riedel as a 'prominent' Al-Qaeda member while others have described him as head of military operations for al-Qaeda. Kashmiri was also charged by the US in a plot against Jyllands-Posten, the Danish newspaper which was at the center of Jyllands-Posten Muhammad cartoons controversy. US officials also believe that Kashmiri was involved in the Camp Chapman attack against the CIA. In January 2010, Indian authorities notified Britain of an al-Qaeda plot to hijack an Indian airlines or Air India plane and crash it into a British city. This information was uncovered from interrogation of Amjad Khwaja, an operative of Harkat-ul-Jihad al-Islami, who had been arrested in India. + +In January 2010, US Defense secretary Robert Gates, while on a visit to Pakistan, said that al-Qaeda was seeking to destabilize the region and planning to provoke a nuclear war between India and Pakistan. + +Internet +Al-Qaeda and its successors have migrated online to escape detection in an atmosphere of increased international vigilance. The group's use of the Internet has grown more sophisticated, with online activities that include financing, recruitment, networking, mobilization, publicity, and information dissemination, gathering and sharing. + +Abu Ayyub al-Masri's al-Qaeda movement in Iraq regularly releases short videos glorifying the activity of jihadist suicide bombers. In addition, both before and after the death of Abu Musab al-Zarqawi (the former leader of al-Qaeda in Iraq), the umbrella organization to which Al-Qaeda in Iraq belongs, the Mujahideen Shura Council, has a regular presence on the Web. + +The range of multimedia content includes guerrilla training clips, stills of victims about to be murdered, testimonials of suicide bombers, and videos that show participation in jihad through stylized portraits of mosques and musical scores. A website associated with Al-Qaeda posted a video of captured American entrepreneur Nick Berg being decapitated in Iraq. Other decapitation videos and pictures, including those of Paul Johnson, Kim Sun-il, and Daniel Pearl, were first posted on jihadist websites. + +In December 2004 an audio message claiming to be from bin Laden was posted directly to a website, rather than sending a copy to al Jazeera as he had done in the past. Al-Qaeda turned to the Internet for release of its videos in order to be certain they would be available unedited, rather than risk the possibility of al Jazeera editing out anything critical of the Saudi royal family. + +Alneda.com and Jehad.net were perhaps the most significant al-Qaeda websites. Alneda was initially taken down by American Jon Messner, but the operators resisted by shifting the site to various servers and strategically shifting content. + +The US government charged a British information technology specialist, Babar Ahmad, with terrorist offences related to his operating a network of English-language al-Qaeda websites, such as Azzam.com. He was convicted and sentenced to years in prison. + +Online communications +In 2007, al-Qaeda released Mujahedeen Secrets, encryption software used for online and cellular communications. A later version, Mujahideen Secrets 2, was released in 2008. + +Aviation network +al-Qaeda is believed to be operating a clandestine aviation network including "several Boeing 727 aircraft", turboprops and executive jets, according to a 2010 Reuters story. Based on a US Department of Homeland Security report, the story said al-Qaeda is possibly using aircraft to transport drugs and weapons from South America to various unstable countries in West Africa. A Boeing 727 can carry up to ten tons of cargo. The drugs eventually are smuggled to Europe for distribution and sale, and the weapons are used in conflicts in Africa and possibly elsewhere. Gunmen with links to al-Qaeda have been increasingly kidnapping Europeans for ransom. The profits from the drug and weapon sales, and kidnappings can, in turn, fund more militant activities. + +Involvement in military conflicts + +The following is a list of military conflicts in which al-Qaeda and its direct affiliates have taken part militarily. + +Alleged CIA involvement + +Experts debate the notion that the al-Qaeda attacks were an indirect consequence of the American CIA's Operation Cyclone program to help the Afghan mujahideen. Robin Cook, British Foreign Secretary from 1997 to 2001, has written that al-Qaeda and bin Laden were "a product of a monumental miscalculation by western security agencies", and that "Al-Qaida, literally 'the database', was originally the computer file of the thousands of mujahideen who were recruited and trained with help from the CIA to defeat the Russians." + +Munir Akram, Permanent Representative of Pakistan to the United Nations from 2002 to 2008, wrote in a letter published in The New York Times on January 19, 2008: + +CNN journalist Peter Bergen, Pakistani ISI Brigadier Mohammad Yousaf, and CIA operatives involved in the Afghan program, such as Vincent Cannistraro, deny that the CIA or other American officials had contact with the foreign mujahideen or bin Laden, or that they armed, trained, coached or indoctrinated them. In his 2004 book Ghost Wars, Steve Coll writes that the CIA had contemplated providing direct support to the foreign mujahideen, but that the idea never moved beyond discussions. + +Bergen and others argue that there was no need to recruit foreigners unfamiliar with the local language, customs or lay of the land since there were a quarter of a million local Afghans willing to fight. Bergen further argues that foreign mujahideen had no need for American funds since they received several million dollars per year from internal sources. Lastly, he argues that Americans could not have trained the foreign mujahideen because Pakistani officials would not allow more than a handful of them to operate in Pakistan and none in Afghanistan, and the Afghan Arabs were almost invariably militant Islamists reflexively hostile to Westerners whether or not the Westerners were helping the Muslim Afghans. + +According to Bergen, who conducted the first television interview with bin Laden in 1997: the idea that "the CIA funded bin Laden or trained bin Laden... [is] a folk myth. There's no evidence of this... Bin Laden had his own money, he was anti-American and he was operating secretly and independently... The real story here is the CIA didn't really have a clue about who this guy was until 1996 when they set up a unit to really start tracking him." + +Jason Burke also wrote: + +Broader influence +Anders Behring Breivik, the perpetrator of the 2011 Norway attacks, was inspired by al-Qaeda, calling it "the most successful revolutionary movement in the world." While admitting different aims, he sought to "create a European version of Al-Qaida." + +The appropriate response to offshoots is a subject of debate. A journalist reported in 2012 that a senior US military planner had asked: "Should we resort to drones and Special Operations raids every time some group raises the black banner of al Qaeda? How long can we continue to chase offshoots of offshoots around the world?" + +Criticism + +According to CNN journalists Peter Bergen and Paul Cruickshank, a number of "religious scholars, former fighters and militants" who previously supported Islamic State of Iraq (ISI) had turned against the Al-Qaeda-supported Iraqi insurgency in 2008; due to ISI's indiscriminate attacks against civilians while targeting US-led coalition forces. American military analyst Bruce Riedel wrote in 2008 that "a wave of revulsion" arose against ISI, which enabled US-allied Sons of Iraq faction to turn various tribal leaders in the Anbar region against the Iraqi insurgency. In response, Bin Laden and Zawahiri issued public statements urging Muslims to rally behind ISI leadership and support the armed struggle against American forces. + +In response to Noman Benotman, a former militant member of the Libyan Islamic Fighting Group (LIFG), went public with an open letter of criticism to Ayman al-Zawahiri in November 2007, after persuading the imprisoned senior leaders of his former group to enter into peace negotiations with the Libyan regime. While Ayman al-Zawahiri announced the affiliation of the group with Al-Qaeda in November 2007, the Libyan government released 90 members of the group from prison several months after "they were said to have renounced violence." + +In 2007, on the anniversary of the September 11 attacks, the Saudi sheikh Salman al-Ouda delivered a personal rebuke to bin Laden. Al-Ouda addressed Al-Qaeda's leader on television asking him: + +According to Pew polls, support for Al-Qaeda had dropped in the Muslim world in the years before 2008. In Saudi Arabia, only ten percent had a favorable view of Al-Qaeda, according to a December 2007 poll by Terror Free Tomorrow, a Washington-based think tank. + +In 2007, the imprisoned Dr. Fadl, who was an influential Afghan Arab and former associate of Ayman al-Zawahiri, withdrew his support from al-Qaeda and criticized the organization in his book Wathiqat Tarshid Al-'Aml Al-Jihadi fi Misr w'Al-'Alam (). In response, Al-Zawahiri accused Dr. Fadl of promoting "an Islam without jihad" that aligns with Western interests and wrote a nearly two hundred pages long treatise, titled "The Exoneration" which appeared on the Internet in March 2008. In his treatise, Zawahiri justified military strikes against US targets as retaliatory attacks to defend Muslim community against American aggression. + +In an online town hall forum conducted in December 2007, Zawahiri denied that al-Qaeda deliberately targeted innocents and accused the American coalition of killing innocent people. Although once associated with al-Qaeda, in September 2009 LIFG completed a new "code" for jihad, a 417-page religious document entitled "Corrective Studies". Given its credibility and the fact that several other prominent Jihadists in the Middle East have turned against Al-Qaeda, the LIFG's reversal may be an important step toward staunching Al-Qaeda's recruitment. + +Other criticisms +Bilal Abdul Kareem, an American journalist based in Syria created a documentary about al-Shabab, Al-Qaeda's affiliate in Somalia. The documentary included interviews with former members of the group who stated their reasons for leaving al-Shabab. The members made accusations of segregation, lack of religious awareness and internal corruption and favoritism. In response to Kareem, the Global Islamic Media Front condemned Kareem, called him a liar, and denied the accusations from the former fighters. + +In mid-2014 after the Islamic State of Iraq and the Levant declared that they had restored the Caliphate, an audio statement was released by the then-spokesman of the group Abu Muhammad al-Adnani claiming that "the legality of all emirates, groups, states, and organizations, becomes null by the expansion of the Caliphate's authority." The speech included a religious refutation of Al-Qaeda for being too lenient regarding Shiites and their refusal to recognize the authority Abu Bakr al-Baghdadi, al-Adnani specifically noting: "It is not suitable for a state to give allegiance to an organization." He also recalled a past instance in which Osama bin Laden called on Al-Qaeda members and supporters to give allegiance to Abu Omar al-Baghdadi when the group was still solely operating in Iraq, as the Islamic State of Iraq, and condemned Ayman al-Zawahiri for not making this same claim for Abu Bakr al-Baghdadi. Zawahiri was encouraging factionalism and division between former allies of ISIL such as the al-Nusra Front. + +See also + + Al-Qaeda involvement in Asia + Al Qaeda Network Exord + Allegations of support system in Pakistan for Osama bin Laden + Belligerents in the Syrian civil war + Bin Laden Issue Station (former CIA unit for tracking bin Laden) + Steven Emerson + Fatawā of Osama bin Laden + International propagation of Salafism and Wahhabism (by region) + Iran – Alleged Al-Qaeda ties + Islamic Military Counter Terrorism Coalition + Operation Cannonball + Psychological warfare + Religious terrorism + Takfir wal-Hijra + Videos and audio recordings of Osama bin Laden + Violent extremism + +Publications + Al Qaeda Handbook + Management of Savagery + +Notes + +References + +Sources + +Bibliography + +Reviews + +Government reports + + + Alt URL + +External links + + + Al-Qaeda in Oxford Islamic Studies Online + Al-Qaeda, Counter Extremism Project profile + 17 de-classified documents captured during the Abbottabad raid and released to the Combating Terrorism Center + + +Media + Peter Taylor.

He invented the voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the president of the Royal Society. With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments, which eventually led to the development of the field of electrochemistry. + +Volta also drew admiration from Napoleon Bonaparte for his invention, and was invited to the Institute of France to demonstrate his invention to the members of the institute. Throughout his life, Volta enjoyed a certain amount of closeness with the emperor who conferred upon him numerous honours. + +Volta held the chair of experimental physics at the University of Pavia for nearly 40 years and was widely idolised by his students. Despite his professional success, Volta was inclined towards domestic life and this was more apparent in his later years when he tended to live secluded from public life and more for the sake of his family. He died in 1827 from a series of illnesses which began in 1823. The SI unit of electric potential is named the volt in his honour. + +Personal life +Volta was born in Como, a town in northern Italy, on 18 February 1745. His father, Filippo Volta, was of noble lineage. His mother, Donna Maddalena, came from the family of the Inzaghis. In 1794, Volta married an aristocratic lady also from Como, Teresa Peregrini, with whom he raised three sons: Zanino, Flaminio, and Luigi. + +Career + +In 1774, he became a professor of physics at the Royal School in Como. A year later, he improved and popularised the electrophorus, a device that produced static electricity. His promotion of it was so extensive that he is often credited with its invention, even though a machine operating on the same principle was described in 1762 by the Swedish experimenter Johan Wilcke. In 1777, he travelled through Switzerland, where he befriended H. B. de Saussure. + +In the years between 1776 and 1778, Volta studied the chemistry of gases. He researched and discovered methane after reading a paper by Benjamin Franklin of the United States on "flammable air". In November 1776, he found methane in the marshes of Angera on Lake Maggiore, and by 1778 he managed to isolate it. He devised experiments such as the ignition of methane by an electric spark in a closed vessel. + +Volta also studied what we now call electrical capacitance, developing separate means to study both electrical potential difference (V) and charge (Q), and discovering that for a given object, they are proportional. This is called Volta's Law of Capacitance, and for this work the unit of electrical potential has been named the volt. + +In 1779, he became a professor of experimental physics at the University of Pavia, a chair that he occupied for almost 40 years. Volta's lectures were so crowded with students that the subsequent emperor Joseph II ordered the construction (based on a project by Leopold Pollack) of a new "physical theater", today the "Aula Volta". Furthermore, the emperor granted Volta substantial funding to equip the physics cabinet with instruments, purchased by Volta in England and France. At the University History Museum of the University of Pavia there are 150 of them, used by Alessandro Volta. + +Volta and Galvani + +Luigi Galvani, an Italian physicist, discovered something he named, "animal electricity" when two different metals were connected in series with a frog's leg and to one another. Volta realised that the frog's leg served as both a conductor of electricity (what we would now call an electrolyte) and as a detector of electricity. He also understood that the frog's legs were irrelevant to the electric current, which was caused by the two differing metals. He replaced the frog's leg with brine-soaked paper, and detected the flow of electricity by other means familiar to him from his previous studies. +In this way he discovered the electrochemical series, and the law that the electromotive force (emf) of a galvanic cell, consisting of a pair of metal electrodes separated by electrolyte, is the difference between their two electrode potentials (thus, two identical electrodes and a common electrolyte give zero net emf). This may be called Volta's Law of the electrochemical series. + +In 1800, as the result of a professional disagreement over the galvanic response advocated by Galvani, Volta invented the voltaic pile, an early electric battery, which produced a steady electric current. Volta had determined that the most effective pair of dissimilar metals to produce electricity was zinc and copper. Initially he experimented with individual cells in series, each cell being a wine goblet filled with brine into which the two dissimilar electrodes were dipped. The voltaic pile replaced the goblets with cardboard soaked in brine. + +Early battery + +In announcing his discovery of the voltaic pile, Volta paid tribute to the influences of William Nicholson, Tiberius Cavallo, and Abraham Bennet. + +The battery made by Volta is credited as one of the first electrochemical cells. It consists of two electrodes: one made of zinc, the other of copper. The electrolyte is either sulfuric acid mixed with water or a form of saltwater brine. The electrolyte exists in the form and . Zinc metal, which is higher in the electrochemical series than both copper and hydrogen, is oxidized to zinc cations (Zn2+) and creates electrons that move to the copper electrode. The positively charged hydrogen ions (protons) capture electrons from the copper electrode, forming bubbles of hydrogen gas, H2. This makes the zinc rod the negative electrode and the copper rod the positive electrode. +Thus, there are two terminals, and an electric current will flow if they are connected. The chemical reactions in this voltaic cell are as follows: + +Zinc: + +Sulfuric acid: + +Copper metal does not react, but rather it functions as a catalyst for the hydrogen-gas formation and an electrode for the electric current. The sulfate anion () does not undergo any chemical reaction either, but migrates to the zinc anode to compensate for the charge of the zinc cations formed there. +However, this cell also has some disadvantages. It is unsafe to handle, since sulfuric acid, even if diluted, can be hazardous. Also, the power of the cell diminishes over time because the hydrogen gas is not released. Instead, it accumulates on the surface of the copper electrode and forms a barrier between the metal and the electrolyte solution. + +Last years and retirement + +In 1809, Volta became associated member of the Royal Institute of the Netherlands. In honour of his work, Volta was made a count by Napoleon Bonaparte in 1810. + +Volta retired in 1819 to his estate in Camnago, a frazione of Como, Italy, now named "Camnago Volta" in his honour. He died there on 5 March 1827, just after his 82nd birthday. Volta's remains were buried in Camnago Volta. + +Legacy +Volta's legacy is celebrated by the Tempio Voltiano memorial located in the public gardens by the lake. There is also a museum that has been built in his honour, which exhibits some of the equipment that Volta used to conduct experiments. Nearby stands the Villa Olmo, which houses the Voltian Foundation, an organization promoting scientific activities. Volta carried out his experimental studies and produced his first inventions near Como. +In the Old Campus of the University of Pavia there is the classroom (Aula Volta) commissioned by Emperor Joseph II to Leopoldo Pollack in 1787 for the lectures of Alessandro Volta, while in the University History Museum there are many scientific instruments that belonged to Volta and his chair and his blackboard. + +His image was depicted on the Italian Lire 10,000 note (1990–1997) along with a sketch of his voltaic pile. + +In late 2017, Nvidia announced a new workstation-focused GPU microarchitecture called Volta. + +The electric eel species Electrophorus voltai, described in 2019 and the strongest bioelectricity producer in nature, was named after Volta. + +Religious beliefs +Volta was raised as a Catholic and for all of his life continued to maintain his belief. Because he was not ordained a clergyman as his family expected, he was sometimes accused of being irreligious and some people have speculated about his possible unbelief, stressing that "he did not join the Church", or that he virtually "ignored the church's call". Nevertheless, he cast out doubts in a declaration of faith in which he said: + + +I do not understand how anyone can doubt the sincerity and constancy of my attachment to the religion which I profess, the Roman, Catholic and Apostolic religion in which I was born and brought up, and of which I have always made confession, externally and internally. I have, indeed, and only too often, failed in the performance of those good works which are the mark of a Catholic Christian, and I have been guilty of many sins: but through the special mercy of God I have never, as far as I know, wavered in my faith... In this faith I recognise a pure gift of God, a supernatural grace; but I have not neglected those human means which confirm belief, and overthrow the doubts which at times arise. I studied attentively the grounds and basis of religion, the works of apologists and assailants, the reasons for and against, and I can say that the result of such study is to clothe religion with such a degree of probability, even for the merely natural reason, that every spirit unperverted by sin and passion, every naturally noble spirit must love and accept it. May this confession which has been asked from me and which I willingly give, written and subscribed by my own hand, with authority to show it to whomsoever you will, for I am not ashamed of the Gospel, may it produce some good fruit! + +Publications + +Lesser known collections + Briefe über thierische elektricität (1900) (Letters about thieric electricity, Available through Worldcat.org libraries, Leipzig, W.

It is formerly a single large constellation in the southern sky. The genitive is "Argus Navis", abbreviated "Arg". Flamsteed and other early modern astronomers called it Navis (the Ship), genitive "Navis", abbreviated "Nav". + +The constellation proved to be of unwieldy size, as it was 28% larger than the next largest constellation and had more than 160 easily visible stars. The 1755 catalogue of Nicolas Louis de Lacaille divided it into the three modern constellations that occupy much of the same area: Carina (the keel), Puppis (the poop deck or stern), and Vela (the sails). + +Argo derived from the ship Argo in Greek mythology, sailed by Jason and the Argonauts to Colchis in search of the Golden Fleece. Some stars of Puppis and Vela can be seen from Mediterranean latitudes in winter and spring, the ship appearing to skim along the "river of the Milky Way." The precession of the equinoxes has caused the position of the stars from Earth's viewpoint to shift southward. Though most of the constellation was visible in Classical times, the constellation is now not easily visible from most of the northern hemisphere. All the stars of Argo Navis are easily visible from the tropics southward and pass near zenith from southern temperate latitudes. The brightest of these is Canopus (α Carinae), the second-brightest night-time star, now assigned to Carina. + +History + +Development of the Greek constellation +Argo Navis is known from Greek texts, which derived it from Egypt around 1000 BC. Plutarch attributed it to the Egyptian "Boat of Osiris." Some academics theorized a Sumerian origin related to the Epic of Gilgamesh, a hypothesis rejected for lack of evidence that Mesopotamian cultures considered these stars, or any portion of them, to form a boat. + +Over time, Argo became identified exclusively with ancient Greek myth of Jason and the Argonauts. In Ptolemy's Almagest, Argo Navis occupies the portion of the Milky Way between Canis Major and Centaurus, with stars marking such details as the "little shield", the "steering-oar", the "mast-holder", and the "stern-ornament", which continued to be reflected in cartographic representations in celestial atlases into the nineteenth century (see below). The ship appeared to rotate about the pole sternwards, so nautically in reverse. Aratus, the Greek poet / historian living in the third century BCE, noted this backward progression writing, "Argo by the Great Dog's [Canis Major's] tail is drawn; for hers is not a usual course, but backward turned she comes ...". + +The constituent modern constellations +In modern times, Argo Navis was considered unwieldy due to its enormous size (28% larger than Hydra, the largest modern constellation). In his 1763 star catalogue, Nicolas Louis de Lacaille explained that there were more than a hundred and sixty stars clearly visible to the naked eye in Navis, and so he used the set of lowercase and uppercase Latin letters three times on portions of the constellation referred to as "Argûs in carina" (Carina, the keel), "Argûs in puppi" (Puppis, the poop deck or stern), and "Argûs in velis" (Vela, the sails). Lacaille replaced Bayer's designations with new ones that followed stellar magnitudes more closely, but used only a single Greek-letter sequence and described the constellation for those stars as "Argûs". Similarly, faint unlettered stars were listed only as in "Argûs". + +The final breakup and abolition of Argo Navis was proposed by Sir John Herschel in 1841 and again in 1844. Despite this, the constellation remained in use in parallel with its constituent parts into the 20th century. In 1922, along with the other constellations, it received a three-letter abbreviation: Arg. The breakup and relegation to a former constellation occurred in 1930 when the IAU defined the 88 modern constellations, formally instituting Carina, Puppis, and Vela, and declaring Argo obsolete. Lacaille's designations were kept in the offspring, so Carina has α, β, and ε; Vela has γ and δ; Puppis has ζ; and so on. As a result of this breakup, Argo Navis is the only one of Ptolemy's 48 constellations that is no longer officially recognized as a single constellation. + +In addition, the constellation Pyxis (the mariner's compass) occupies an area near what in antiquity was considered part of Argo's mast. Some recent authors state that the compass was part of the ship, but magnetic compasses were unknown in ancient Greek times. Lacaille considered it a separate constellation representing a modern scientific instrument (like Microscopium and Telescopium), that he created for maps of the stars of the southern hemisphere. Pyxis was listed among his 14 new constellations. In 1844, John Herschel suggested formalizing the mast as a new constellation, Malus, to replace Lacaille's Pyxis, but the idea did not catch on. Similarly, an effort by Edmond Halley to detach the "cloud of mist" at the prow of Argo Navis to form a new constellation named Robur Carolinum (Charles' Oak) in honor of King Charles II, his patron, was unsuccessful. + +Representations in other cultures +In Vedic period astronomy, which drew its zodiac signs and many constellations from the period of the Indo-Greek Kingdom, Indian observers saw the asterism as a boat. + +The Māori had several names for the constellation, including Te Waka-o-Tamarereti (the canoe of Tamarereti), Te Kohi-a-Autahi (an expression meaning "cold of autumn settling down on land and water"), and Te Kohi. + +See also +Asterism (astronomy) +List of stars in Argo Navis + +Footnotes + +References + +External links + +Starry Night Photography : Argo Navis Image +Ian Ridpath's Star Tales – Argo Navis +Warburg Institute Iconographic Database – Argo (Navis) (medieval and early modern images of Argo Navis) + + +Constellations listed by Ptolemy +Former constellations +In Greek mythology, Andromeda (; or ) is the daughter of Cepheus, the king of Aethiopia, and his wife, Cassiopeia. When Cassiopeia boasts that she (or her daughter) is more beautiful than the Nereids, Poseidon sends the sea monster Cetus to ravage the coast of Aethiopia as divine punishment. Andromeda is chained to a rock as a sacrifice to sate the monster, but is saved from death by Perseus, who marries her and takes her to Greece to reign as his queen. + +As a subject, Andromeda has been popular in art since classical times; rescued by a Greek hero, Andromeda's narration is considered the forerunner to the "princess and dragon" motif. From the Renaissance, interest revived in the original story, typically as derived from Ovid's Metamorphoses. The story has appeared many times in such diverse media as plays, poetry, novels, operas, classical and popular music, film, and paintings. A significant part of the northern sky contains several constellations named after the story's figures; in particular, the constellation Andromeda is named after her. + +The Andromeda tradition, from classical times onwards, has incorporated elements of other stories, including Saint George and the Dragon, introducing a horse for the hero, and the tale of Pegasus, Bellerophon's winged horse. Ludovico Ariosto's epic poem , which tells a similar story, has introduced further confusion. The tradition has been criticized for depicting the princess of Aethiopia as white; few artists have chosen to portray her as dark-skinned, despite Ovid's account of her. Others have noted that Perseus's liberation of Andromeda was a popular choice of subject among male artists, reinforcing a narrative of male superiority with its powerful male hero and its submissive female in bondage. + +Etymology + +The name Andromeda is from the Greek , perhaps meaning 'mindful of her husband'. The name is from the noun meaning 'man', and a verb, whether , , or , all related to , the likely origin of the name of Medea, the sorceress. + +Classical mythology + +Central story + +In Greek mythology, Andromeda is the daughter of Cepheus and Cassiopeia, king and queen of ancient Aethiopia. Her mother Cassiopeia foolishly boasts that she is more beautiful than the Nereids, a display of hubris by a human that is unacceptable to the gods. To punish the queen for her arrogance, Poseidon floods the Ethiopian coast and sends a sea monster named Cetus to ravage the kingdom's inhabitants. In desperation, King Cepheus consults the oracle of Ammon, who announces that no respite can be found until the king sacrifices his daughter, Andromeda, to the monster. She is thus stripped naked and chained to a rock in Jaffa by the sea to await her death. Perseus is just then flying near the coast of Ethiopia on his winged sandals or on Pegasus the winged horse, having slain the Gorgon Medusa and carrying her severed head, which instantly turns to stone any who look at it. Upon seeing Andromeda bound to the rock, Perseus falls in love with her, and he secures Cepheus' promise of her hand in marriage if he can save her. Perseus kills the monster with the magical sword he had used against Medusa, saving Andromeda. Preparations are then made for their marriage, in spite of her having been previously promised to her uncle, Phineus. At the wedding, a quarrel between the rivals ends when Perseus shows Medusa's head to Phineus and his allies, turning them to stone. + +Andromeda follows her husband to his native island of Serifos, where he rescues his mother, Danaë. They next go to Argos, where Perseus is the rightful heir to the throne. However, after accidentally killing his grandfather Acrisius, the king of Argos, Perseus chooses to become king of neighboring Tiryns instead. The mythographer Apollodorus states that Perseus and Andromeda have six sons: Perses, Alcaeus, Heleus, Mestor, Sthenelus, Electryon, and a daughter, Gorgophone. Their descendants rule Mycenae from Electryon down to Eurystheus, after whom Atreus attains the kingdom. The Greek hero Heracles is also a descendant, as his mother Alcmene is the daughter of Electryon. + +According to the Catasterismi, Andromeda is placed in the sky by Athena as the constellation Andromeda, in a pose with her limbs outstretched, similar to when she was chained to the rock, in commemoration of Perseus' bravery in fighting the sea monster. + +In classical art + +The myth of Andromeda was represented in the art of ancient Greece and of Rome in media including red-figure pottery such as pelike jars, frescoes, and mosaics. Depictions range from straightforward representations of scenes from the myth, such as of Andromeda being tied up for sacrifice, to more ambiguous portrayals with different events depicted in the same painting, as at the Roman villa in Boscotrecase, where Perseus is shown twice, space standing in for time. Favoured scenes changed with time: until the 4th century BC, Perseus was shown decapitating Medusa, while after that, and in Roman portrayals, he was shown rescuing Andromeda. + +Variants + +There are several variants of the legend. In Hyginus's account, Perseus does not ask for Andromeda's hand in marriage before saving her, and when he afterwards intends to keep her for his wife, both her father Cepheus and her uncle Phineas plot against him, and Perseus resorts to using Medusa's head to turn them to stone. In contrast, Ovid states that Perseus kills Cetus with his magical sword, even though he also carries Medusa's head, which could easily turn the monster to stone (and Perseus does use Medusa's head for this purpose in other situations). The earliest straightforward account of Perseus using Medusa's head against Cetus, however, is from the later 2nd-century AD satirist Lucian. + +The 12th-century Byzantine writer John Tzetzes says that Cetus swallows Perseus, who kills the monster by hacking his way out with his sword. Conon places the story in Joppa (Iope or Jaffa, on the coast of modern Israel), and makes Andromeda's uncles Phineus and Phoinix rivals for her hand in marriage; her father Cepheus contrives to have Phoinix abduct her in a ship named Cetos from a small island she visits to make sacrifices to Aphrodite, and Perseus, sailing nearby, intercepts and destroys Cetos and its crew, who are "petrified by shock" at his bravery. + +Constellations + +Andromeda is represented in the Northern sky by the constellation Andromeda, mentioned by the astronomer Ptolemy in the 2nd century, which contains the Andromeda Galaxy. Several constellations are associated with the myth. Viewing the fainter stars visible to the naked eye, the constellations are rendered as a maiden (Andromeda) chained up, facing or turning away from the ecliptic; a warrior (Perseus), often depicted holding the head of Medusa, next to Andromeda; a huge man (Cepheus) wearing a crown, upside down with respect to the ecliptic; a smaller figure (Cassiopeia) next to the man, sitting on a chair; a whale or sea monster (Cetus) just beyond Pisces, to the south-east; the flying horse Pegasus, who was born from the stump of Medusa's neck after Perseus had decapitated her; the paired fish of the constellation Pisces, that in myth were caught by Dictys the fisherman who was brother of Polydectes, king of Seriphos, the place where Perseus and his mother Danaë were stranded. + +In literature + +In poetry + +George Chapman's poem in heroic couplets Andromeda liberata, Or the nuptials of Perseus and Andromeda, was written for the 1614 wedding of Robert Carr, 1st Earl of Somerset and Frances Howard. The wedding, which led to a "train of intrigue and murder and executions, was the scandal of the age." Scholars have been surprised that Chapman should have celebrated such a marriage, and his choice of an allegory of the Perseus-Andromeda myth for the purpose. The poem infuriated both Carr and the Earl of Essex, causing Chapman to publish a "justification" of his approach. Chapman's poem sees human nature as chaotic and disorderly, like the sea monster, opposed by Andromeda's beauty and Perseus's balanced nature; their union brings about an astrological harmony of Venus and Mars which perfects the character of Perseus, since Venus was thought always to dominate Mars. Unfortunately for Chapman, Essex supposed that he was represented by the "barraine rocke" that Andromeda was chained up to: Howard had divorced Essex on the grounds that he could not consummate their marriage, and she had married Carr with her hair untied, indicating that she was a virgin. Further, the poem could be read as having dangerous political implications, involving King James. + +Ludovico Ariosto's influential epic poem (1516–1532) features a pagan princess named Angelica who at one point is in exactly the same situation as Andromeda, chained naked to a rock on the sea as a sacrifice to a sea monster, and is saved at the last minute by the Saracen knight Ruggiero. Images of Angelica and Ruggiero are often hard to distinguish from those of Andromeda and Perseus. + +John Keats's 1819 sonnet On the Sonnet compares the restricted sonnet form to the bound Andromeda as being "Fetter'd, in spite of pained loveliness". William Morris retells the story of Perseus and Andromeda in his epic 1868 poem The Earthly Paradise, in the section April: The Doom of King Acrisius. Gerard Manley Hopkins's sonnet Andromeda (1879) has invited many interpretations. Charles Kingsley's hexameter poem retelling the myth, Andromeda (1858), was set to music by Cyril Rootham in his Andromeda (1905). + +In novels + +In the 1851 novel Moby-Dick, Herman Melville's narrator Ishmael discusses the Perseus and Andromeda myth in two chapters. Chapter 55, "Of the Monstrous Pictures of Whales," mentions depictions of Perseus rescuing Andromeda from Cetus in artwork by Guido Reni and William Hogarth. In Chapter 82, "The Honor and Glory of Whaling," Ishmael recounts the myth and says that the Romans found a giant whale skeleton in Joppa that they believed to be the skeleton of Cetus. Jules Laforgue included what Knutson calls "a remarkable satirical adaptation", , in his 1887 . All the traditional elements are present, along with elements of fantasy and lyricism, but only to allow Laforgue to parody them. The romance, crime, and thriller writer Carlton Dawe's 1909 novel The New Andromeda (published in America as The Woman, the Man, and the Monster) offers what was called at the time a "wholly unconventional" retelling of the Andromeda story in a modern setting. Robert Nichols's 1923 short story Perseus and Andromeda satirically retells the story in contrasting styles. In her 1978 novel The Sea, the Sea, Iris Murdoch uses the Andromeda myth, as presented in a reproduction of Titian's painting Perseus and Andromeda in the Wallace Collection in London, to reflect the character and motives of her characters. Charles has an LSD-fuelled vision of a serpent; when he returns to London, he becomes ill on seeing Titian's painting, whereupon his cousin James comes to his rescue. + +In the performing arts + +In theatre + +The theme, well suited to the stage, was introduced to theatre by Sophocles in his lost tragedy Andromeda (5th century BC), which survives only in fragments. Euripides took up the theme in his play of the same name (412 BC), also now lost, but parodied by Aristophanes in his comedy (411 BC) and influential in the ancient world. In the parody, Mnesilochus is shaved and dressed as a woman to gain entrance to the women's secret rites, held in honour of the fertility goddess Demeter. Euripides swoops mock-heroically across the stage as Perseus on a theatrical crane, trying and failing to rescue Mnesilochus, who responds by acting out the role of Andromeda. + +The legend of Perseus and Andromeda became popular among playwrights in the 17th century, including Lope de Vega's 1621 , and Pierre Corneille's famous 1650 verse play , with dramatic stage machinery effects, including Perseus astride Pegasus as he battles the sea monster. The play, a , presented to King Louis XIV of France and performed by the , the royal troupe, had enormous and lasting success, continuing in production until 1660, to Corneille's surprise. The production was a radical departure from the tradition of French theatre, based in part on the Italian tradition of operas about Andromeda; it was semi-operatic, with many songs, set to music by D'Assouci, alongside the stage scenery by the Italian painter Giacomo Torelli. Corneille chose to present Andromeda fully-clothed, supposing that her nakedness had been merely a painterly tradition; Knutson comments that in so doing, "he unintentionally broke the last link with the early erotic myth." + +Pedro Calderón de la Barca's 1653 was also inspired by Corneille, and like was heavily embellished with the playwrights' inventions and traditional additions. + +The Andromeda theme was explored later in works such as Muriel Stuart's closet drama Andromeda Unfettered (1922), featuring: Andromeda, "the spirit of woman"; Perseus, "the new spirit of man"; a chorus of "women who desire the old thrall"; and a chorus of "women who crave the new freedom". + +In music and opera + +The Andromeda theme has been popular in classical music since the 17th century. It became a theme for opera from the 16th century, with an Andromeda in Italy in 1587. This was followed by Claudio Monteverdi's Andromeda (1618-1620). Benedetto Ferrari's Andromeda, with music by Francesco Manelli, was the first opera performed in a public theatre, Venice's Teatro San Cassiano, in 1637. This set the pattern for Italian opera for several centuries. + +Jean-Baptiste Lully's (1682), a tragédie lyrique in 5 acts, was inspired by the popularity of Corneille's play. The libretto was by Philippe Quinault, and a real horse appeared on stage as Pegasus. saw an initial run of 33 consecutive performances, 45 in total, exceptional at that time. Written for King Louis XIV, it has been described as Lully's "greatest creation[...] considered the crowning achievement of 17th century French music theatre. Filled with dancing, fight scenes, monsters and special effects[...] [a] truly spectacular opera". Michael Haydn wrote the music for another in 1797. A total of seventeen Andromeda operas were created in Italy in the 18th century. + +Other classical works have taken a variety of forms including (1726), a pasticcio-serenata on the subject of Perseus freeing Andromeda, by a team of composers including Vivaldi, and Carl Ditters von Dittersdorf's Symphony in F (Perseus' Rescue of Andromeda) and Symphony in D (The Petrification of Phineus and his Friends), Nos. 4 and 5 of his Symphonies after Ovid's Metamorphoses (). + +In the 19th century, Augusta Holmès composed the symphonic poem (1883). In 2019, Caroline Mallonée wrote her Portraits of Andromeda for cello and string orchestra. + +In popular music, the theme is employed in tracks on Weyes Blood's 2019 album Titanic Rising and on Ensiferum's 2020 album Thalassic. + +In film + +The 1981 film Clash of the Titans is loosely based on the story of Perseus, Andromeda, and Cassiopeia. In the film the monster is a kraken, a giant squid-like sea monster in Norse mythology, rather than the whale-like Cetos of Greek mythology. Perseus defeats the sea monster by showing it Medusa's face to turn it into stone, rather than by using his magical sword, and rides Pegasus. + +The 2010 remake with the same title, adapts the original story. Andromeda is set to be sacrificed to the kraken but is saved by Perseus. The historian and filmmaker Henry Louis Gates Jr. criticizes both the original film and its remake for using white actresses to portray the Ethiopian princess Andromeda. + +In art + +Merged traditions + +The legend of Saint George and the Dragon, in which a courageous knight rescues a princess from a monster (with clear parallels to the Andromeda myth), became a popular subject for art in the Late Middle Ages, and artists drew from both traditions. One result is that Perseus is often shown with the flying horse Pegasus when fighting the sea monster, even though classical sources consistently state that he flew using winged sandals. + +Idealized beauty to realism + +Andromeda, and her role in the popular myth of Perseus, has been the subject of numerous ancient and modern works of art, where she is represented as a bound and helpless, typically beautiful, young woman placed in terrible danger, who must be saved through the unswerving courage of a hero who loves her. She is often shown, as by Rubens, with Perseus and the flying horse Pegasus at the moment she is freed. Rembrandt, in contrast, shows a suffering Andromeda, frightened and alone. She is depicted naturalistically, exemplifying the painter's rejection of idealized beauty. Frederic, Lord Leighton's Gothic style 1891 Perseus and Andromeda painting presents the white body of Andromeda in pure and untouched innocence, indicating an unfair sacrifice for a divine punishment that was not directed towards her, but to her mother. Pegasus and Perseus are surrounded by a halo of light that connects them visually to the white body of the princess. + +Varied materials and approaches + +Apart from oil on canvas, artists have used a variety of materials to depict the myth of Andromeda, including the sculptor Domenico Guidi's marble, and François Boucher's etching. In modern art of the 20th century, artists moved to depict the myth in new ways. Félix Vallotton's 1910 Perseus Killing the Dragon is one of several paintings, such as his 1908 The Rape of Europa, in which the artist depicts human bodies using a harsh light which makes them appear brutal. +Alexander Liberman's 1962 Andromeda is a black circle on a white field, transected by purple and dark green crescent arcs. + +Analysis + +Ethnicity + +Andromeda was the daughter of the king and queen of Aethiopia, which ancient Greeks located at the edge of the world in Nubia, the lands south of Egypt. The term Aithiops was applied to peoples who dwelt above the equator, between the Atlantic and Indian Oceans. Homer says the Ethiopians live "at the world's end, and lie in two halves, the one looking West and the other East". The 5th-century BC historian Herodotus writes that "Where south inclines westwards, the part of the world stretching farthest towards the sunset is Ethiopia", and also included a plan by Cambyses II of Persia to invade Ethiopia (Kush). + +By the 1st century BC a rival location for Andromeda's story had become established: an outcrop of rocks near the ancient port city of Joppa, as reported by Pomponius Mela, the traveller Pausanias, the geographer Strabo, and the historian Josephus. A case has been made that this new version of the myth was exploited to enhance the fame and serve the local tourist trade of Joppa, which also became connected with the biblical story of Jonah and yet another huge sea creature. This was at odds with Andromeda's African origins, adding to the confusion already surrounding her ethnicity, as reflected in 5th-century BC Greek vase images showing Andromeda attended by dark-skinned African servants and wearing clothing that would have looked foreign to Greeks, yet with light skin. + +In the Greek Anthology, Philodemus (1st century BC) wrote about the "Indian Andromeda". + +The art historian Elizabeth McGrath discusses the tradition, as promoted by the influential Roman poet Ovid, that Andromeda was a dark-skinned woman of either Ethiopian or Indian origin. In his Heroides, Ovid has Sappho explain to Phaon: "If I'm not pale, Andromeda pleased Perseus, dark with the colour of her father Cepheus's land. And often white pigeons mate with other hues, and the dark turtledove's loved by emerald birds"; the Latin word Ovid uses here for 'dark Andromeda' refers to the colour black or brown. Elsewhere he says that Perseus brought Andromeda from "darkest" India and declares "Nor was Andromeda's colour any problem to her wing-footed aerial lover" adding that "White suits dark girls; you looked so attractive in white, Andromeda". Ovid's account of Andromeda's story follows Euripides' play Andromeda in having Perseus initially mistake the chained Andromeda for a statue of marble, which has been taken to mean she was light-skinned; but since statues in Ovid's time were commonly painted to look like living people, her skin could have been of any colour. The ambiguity is reflected in a description by the 2nd-century AD sophist Philostratus of a painting depicting Perseus and Andromeda. He emphasizes the painting's Ethiopian setting, and notes that Andromeda "is charming in that she is fair of skin though in Ethiopia," in clear contrast to the other "charming Ethiopians with their strange coloring and their grim smiles" who have assembled to cheer Perseus in this picture. + +Artworks in the modern era continue to portray Andromeda as fair-skinned, regardless of her stated origins; only a small minority of artists, such as an engraving after Abraham van Diepenbeeck, have chosen to show her as dark. The journalist Patricia Yaker Ekall comments that even this work depicts Andromeda with "European features". She suggests that the "narrative" of white superiority took precedence, and that "the visual of a white man rescuing a chained up black woman would have been too much of a trigger". + +Bondage and rescue + +The imagery of Perseus and Andromeda was depicted by many artists of the Victorian era. Adrienne Munich states that most of these choose the moment after the hero Perseus has killed Medusa and is preparing to "slay the dragon and unbind the maiden". In her view, this transitional moment just precedes "the hero's final test of manhood before entering adult sexuality". Andromeda, on the other hand, "has no story, but she has a role and a lineage", being a princess, and having "attributes: chains, nakedness, flowing hair, beauty, virginity. Without a voice in her fate, she neither defies the gods nor chooses her mate." Munich comments that given that most of the artists were men, "it can be thought of as a male myth", providing convenient gender roles. She cites Catherine MacKinnon's description of the gender differences as "the erotization of dominance and submission": the male gets the power and the female is submissive. Further, the rescue myth provides a "veneer of charity" over the themes of aggression and possession. + +Munich likens the effect to John Everett Millais's 1870 painting The Knight Errant, where the knight, "errant like Oedipus", finds a man sexually assaulting a bound and naked woman, which she calls a Freudian "primal scene". The knight kills the man and frees the woman. She asks whether Millais's knight is hiding from the woman's body, or demonstrating self-control, or whether he has "killed his own more aggressive self". She states that similar psychological themes are implied by the story of Perseus and Andromeda: Perseus makes Andromeda into a mother, thus Oedipally "conflating the purpose of his quest with the goal of finding a wife." + +As for the bondage, Munich notes that the Victorian critic John Ruskin attacked male exploitation of what she calls "suffering nudes as subjects for titillating pictures." "Andromeda" is, she writes, the name of a type of "debased" imagery. She gives as example Gustave Doré's drawing of the voluptuously chained-up Angelica for , where "torment combines with an artistic pose, giving a new meaning to the concept of the 'pin-up'." She notes Ruskin's assertion that the image linked nude prostitutes to the naked Christ, both perverting the meaning of Andromeda's suffering and "blasphem[ing] Christ's sacrifice". + +Further, Munich writes, Andromeda's name means 'Ruler of Men', hinting at her power; and indeed, she can be seen as "the good sister" of the monstrous female, the Medusa who turns men to stone. In psychological terms, she comments, "by slaying the Medusa and freeing Andromeda, the hero tames the chaotic female, the very sign of nature, simultaneously choosing and constructing the socially defined and acceptable female behavior." + +The scholar of literature Harold Knutson describes the story as having a "disturbing sensuality", which together with the evident injustice of Andromeda's "undeserved sacrifice, create a curiously ambiguous effect". He suggests that in the earlier Palestinian version, the woman was the object of desire, Aphrodite/Ishtar/Astarte, and the hero was the sun god Marduk. The monster was woman in evil form, so chaining her human form would keep her from further evil. Knutson comments that the myth illustrates "the ambiguous male view of the eternal female principle." + +Knutson writes that a similar pattern is seen in several other myths, including Heracles' rescue of Hesione; Jason's rescue of Medea from the hundred-eyed dragon; Cadmus's rescue of Harmonia from a dragon; and in an early version of another tale, Theseus's rescue of Ariadne from the Minotaur. He comments that all of this points to "the richness of the [story's] archetypal model", citing Hudo Hetzner's analysis of the many stories that involve a hero rescuing a maiden from a monster. The beast may be a sea-monster, or it may be a dragon that lives in a cave and terrifies a whole country, or the monstrous Count Dracula who lives in a castle. + +See also + + Hesione – saved by Heracles from a sea monster + Iphigenia – sacrificed to the goddess Artemis (or rescued, depending on the version) + +References + +Sources + + Apollodorus, Apollodorus, The Library, with an English Translation by Sir James George Frazer, F.B.A., F.R.S. in 2 Volumes, Cambridge, Massachusetts, Harvard University Press; London, William Heinemann Ltd., 1921. .

Its name means "pump" in Latin and Greek; it represents an air pump. Originally Antlia Pneumatica, the constellation was established by Nicolas-Louis de Lacaille in the 18th century. Its non-specific (single-word) name, already in limited use, was preferred by John Herschel then welcomed by the astronomic community which officially accepted this. North of stars forming some of the sails of the ship Argo Navis (the constellation Vela), Antlia is completely visible from latitudes south of 49 degrees north. + +Antlia is a faint constellation; its brightest star is Alpha Antliae, an orange giant that is a suspected variable star, ranging between apparent magnitudes 4.22 and 4.29. S Antliae is an eclipsing binary star system, changing in brightness as one star passes in front of the other. Sharing a common envelope, the stars are so close they will one day merge to form a single star. Two star systems with known exoplanets, HD 93083 and WASP-66, lie within Antlia, as do NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy. + +History + +The French astronomer Nicolas-Louis de Lacaille first described the constellation in French as la Machine Pneumatique (the Pneumatic Machine) in 1751–52, commemorating the air pump invented by the French physicist Denis Papin. De Lacaille had observed and catalogued almost 10,000 southern stars during a two-year stay at the Cape of Good Hope, devising fourteen new constellations in uncharted regions of the Southern Celestial Hemisphere not visible from Europe. He named all but one in honour of instruments that symbolised the Age of Enlightenment. Lacaille depicted Antlia as a single-cylinder vacuum pump used in Papin's initial experiments, while German astronomer Johann Bode chose the more advanced double-cylinder version. Lacaille Latinised the name to Antlia pneumatica on his 1763 chart. English astronomer John Herschel proposed shrinking the name to one word in 1844, noting that Lacaille himself had abbreviated his constellations thus on occasion. This was universally adopted. The International Astronomical Union adopted it as one of the 88 modern constellations in 1922. + +Although visible to the Ancient Greeks, Antlia's stars were too faint to have been commonly recognised as a figurative object, or part of one, in ancient asterisms. The stars that now comprise Antlia are in a zone of the sky associated with the asterism/old constellation Argo Navis, the ship, the Argo, of the Argonauts, in its latter centuries. This, due to its immense size, was split into hull, poop deck and sails by Lacaille in 1763. Ridpath reports that due to their faintness, the stars of Antlia did not make up part of the classical depiction of Argo Navis. + +In non-Western astronomy +Chinese astronomers were able to view what is modern Antlia from their latitudes, and incorporated its stars into two different constellations. Several stars in the southern part of Antlia were a portion of "Dong'ou", which represented an area in southern China. Furthermore, Epsilon, Eta, and Theta Antliae were incorporated into the celestial temple, which also contained stars from modern Pyxis. + +Characteristics +Covering 238.9 square degrees and hence 0.579% of the sky, Antlia ranks 62nd of the 88 modern constellations by area. Its position in the Southern Celestial Hemisphere means that the whole constellation is visible to observers south of 49°N. Hydra the sea snake runs along the length of its northern border, while Pyxis the compass, Vela the sails, and Centaurus the centaur line it to the west, south and east respectively. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union, is "Ant". The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon with an east side, south side and ten other sides (facing the two other cardinal compass points) (illustrated in infobox at top-right). In the equatorial coordinate system, the right ascension coordinates of these borders lie between and , while the declination coordinates are between −24.54° and −40.42°. + +Features + +Stars + +Lacaille gave nine stars Bayer designations, labelling them Alpha through to Theta, combining two stars next to each other as Zeta. Gould later added a tenth, Iota Antliae. Beta and Gamma Antliae (now HR 4339 and HD 90156) ended up in the neighbouring constellation Hydra once the constellation boundaries were delineated in 1930. Within the constellation's borders, there are 42 stars brighter than or equal to apparent magnitude 6.5. + +The constellation's two brightest stars—Alpha and Epsilon Antliae—shine with a reddish tinge. Alpha is an orange giant of spectral type K4III that is a suspected variable star, ranging between apparent magnitudes 4.22 and 4.29. It is located 320 ± 10 light-years away from Earth. Estimated to be shining with around 480 to 555 times the luminosity of the Sun, it is most likely an ageing star that is brightening and on its way to becoming a Mira variable star, having converted all its core fuel into carbon. Located 590 ± 30 light-years from Earth, Epsilon Antliae is an evolved orange giant star of spectral type K3 IIIa, that has swollen to have a diameter about 69 times that of the Sun, and a luminosity of around 1279 Suns. It is slightly variable. At the other end of Antlia, Iota Antliae is likewise an orange giant of spectral type K1 III. It is 202 ± 2 light-years distant. + +Located near Alpha is Delta Antliae, a binary star, 450 ± 10 light-years distant from Earth. The primary is a blue-white main sequence star of spectral type B9.5V and magnitude 5.6, and the secondary is a yellow-white main sequence star of spectral type F9Ve and magnitude 9.6. Zeta Antliae is a wide optical double star. The brighter star—Zeta1 Antliae—is 410 ± 40 light-years distant and has a magnitude of 5.74, though it is a true binary star system composed of two white main sequence stars of magnitudes 6.20 and 7.01 that are separated by 8.042 arcseconds. The fainter star—Zeta2 Antliae—is 386 ± 5 light-years distant and of magnitude 5.9. Eta Antliae is another double composed of a yellow white star of spectral type F1V and magnitude 5.31, with a companion of magnitude 11.3. Theta Antliae is likewise double, most likely composed of an A-type main sequence star and a yellow giant. S Antliae is an eclipsing binary star system that varies in apparent magnitude from 6.27 to 6.83 over a period of 15.6 hours. The system is classed as a W Ursae Majoris variable—the primary is hotter than the secondary and the drop in magnitude is caused by the latter passing in front of the former. Calculating the properties of the component stars from the orbital period indicates that the primary star has a mass 1.94 times and a diameter 2.026 times that of the Sun, and the secondary has a mass 0.76 times and a diameter 1.322 times that of the Sun. The two stars have similar luminosity and spectral type as they have a common envelope and share stellar material. The system is thought to be around 5–6 billion years old. The two stars will eventually merge to form a single fast-spinning star. + +T Antliae is a yellow-white supergiant of spectral type F6Iab and Classical Cepheid variable ranging between magnitude 8.88 and 9.82 over 5.9 days. U Antliae is a red C-type carbon star and is an irregular variable that ranges between magnitudes 5.27 and 6.04. At 910 ± 50 light-years distant, it is around 5819 times as luminous as the Sun. BF Antliae is a Delta Scuti variable that varies by 0.01 of a magnitude. HR 4049, also known as AG Antliae, is an unusual hot variable ageing star of spectral type B9.5Ib-II. It is undergoing intense loss of mass and is a unique variable that does not belong to any class of known variable star, ranging between magnitudes 5.29 and 5.83 with a period of 429 days. It is around 6000 light-years away from Earth. UX Antliae is an R Coronae Borealis variable with a baseline apparent magnitude of around 11.85, with irregular dimmings down to below magnitude 18.0. A luminous and remote star, it is a supergiant with a spectrum resembling that of a yellow-white F-type star but it has almost no hydrogen. + +HD 93083 is an orange dwarf star of spectral type K3V that is smaller and cooler than the Sun. It has a planet that was discovered by the radial velocity method with the HARPS spectrograph in 2005. About as massive as Saturn, the planet orbits its star with a period of 143 days at a mean distance of 0.477 AU. WASP-66 is a sunlike star of spectral type F4V. A planet with 2.3 times the mass of Jupiter orbits it every 4 days, discovered by the transit method in 2012. DEN 1048-3956 is a brown dwarf of spectral type M8 located around 13 light-years distant from Earth. At magnitude 17 it is much too faint to be seen with the unaided eye. It has a surface temperature of about 2500 K. Two powerful flares lasting 4–5 minutes each were detected in 2002. 2MASS 0939-2448 is a system of two cool and faint brown dwarfs, probably with effective temperatures of about 500 and 700 K and masses of about 25 and 40 times that of Jupiter, though it is also possible that both objects have temperatures of 600 K and 30 Jupiter masses. + +Deep-sky objects + +Antlia contains many faint galaxies, the brightest of which is NGC 2997 at magnitude 10.6. It is a loosely wound face-on spiral galaxy of type Sc. Though nondescript in most amateur telescopes, it presents bright clusters of young stars and many dark dust lanes in photographs. Discovered in 1997, the Antlia Dwarf is a 14.8m dwarf spheroidal galaxy that belongs to the Local Group of galaxies.

It was (as ) one of the Greek bulk (namely 48) described by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations designated by the International Astronomical Union. + +The orange supergiant Beta Arae, to us its brightest star measured with near-constant apparent magnitude of 2.85, is marginally brighter than blue-white Alpha Arae. Seven star systems are known to host planets. Sunlike Mu Arae hosts four known planets. Gliese 676 is a (gravity-paired) binary red dwarf system with four known planets. + +The Milky Way crosses the northwestern part of Ara. Within the constellation is Westerlund 1, a super star cluster that contains the red supergiant Westerlund 1-26, one of the largest stars known. + +History + +In ancient Greek mythology, Ara was identified as the altar where the gods first made offerings and formed an alliance before defeating the Titans. One of the southernmost constellations depicted by Ptolemy, it had been recorded by Aratus in 270 BC as lying close to the horizon, and the Almagest portrays stars as far south as Gamma Arae. Professor Bradley Schaefer proposes such Ancients must have been able to see as far south as Zeta Arae, for a pattern that looked like an altar. + +In illustrations, Ara is usually depicted as compact classical altar with its smoke 'rising' southward. However, depictions often vary. In the early days of printing, a 1482 woodcut of Gaius Julius Hyginus's classic Poeticon Astronomicon depicts the altar as surrounded by demons. Johann Bayer in 1603 depicted Ara as an altar with burning incense. Hyginus depicted the same though his featured devils on either side of the flames. Willem Blaeu, a Dutch uranographer of the 16th and 17th centuries, drew Ara as an altar for sacrifices, with a burning animal offering unusually whose smoke rises northward, represented by Alpha Arae. + +The Castle of Knowledge by Robert Record of 1556 lists the constellation stating that "Under the Scorpions tayle, standeth the Altar."; a decade later a translation of a fairly recent mainly astrological work by Marcellus Palingenius of 1565, by Barnabe Googe states "Here mayst thou both the Altar, and the myghty Cup beholde." + +Equivalents +In Chinese astronomy, the stars of the constellation Ara lie within The Azure Dragon of the East (東方青龍, Dōng Fāng Qīng Lóng). Five stars of Ara formed Guī (龜), a tortoise, while another three formed Chǔ (杵), a pestle. + +The Wardaman people of the Northern Territory in Australia saw the stars of Ara and the neighbouring constellation Pavo as flying foxes. + +Characteristics +Covering 237.1 square degrees and hence 0.575% of the sky, Ara ranks 63rd of the 88 modern constellations by area. Its position in the Southern Celestial Hemisphere means that the whole constellation is visible to observers south of 22°N. Scorpius runs along the length of its northern border, while Norma and Triangulum Australe border it to the west, Apus to the south, and Pavo and Telescopium to the east respectively. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union, is "Ara". The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of twelve segments. In the equatorial coordinate system, the right ascension coordinates of these borders lie between and , while the declination coordinates are between −45.49° and −67.69°. + +Features + +Stars + +Bayer gave eight stars Bayer designations, labelling them Alpha through to Theta, though he had never seen the constellation directly as it never rises above the horizon in Germany. After charting the southern constellations, French astronomer Nicolas-Louis de Lacaille recharted the stars of Ara from Alpha though to Sigma, including three pairs of stars next to each other as Epsilon, Kappa and Nu. + +Ara contains part of the Milky Way to the south of Scorpius and thus has rich star fields. Within the constellation's borders, there are 71 stars brighter than or equal to apparent magnitude 6.5. + +Just shading Alpha Arae, Beta Arae is the brightest star in the constellation. It is an orange-hued star of spectral type K3Ib-IIa that has been classified as a supergiant or bright giant, that is around 650 light-years from Earth. It is around 8.21 times as massive and 5,636 times as luminous as the Sun. At apparent magnitude 2.85, this difference in brightness between the two is undetectable by the unaided eye. Close to Beta Arae is Gamma Arae, a blue-hued supergiant of spectral type B1Ib. Of apparent magnitude 3.3, it is 1110 ± 60 light-years from Earth. It has been estimated to be between 12.5 and 25 times as massive as the Sun, and have around 120,000 times its luminosity. + +Alpha Arae is a blue-white main sequence star of magnitude 2.95, that is 270 ± 20 light-years from Earth. This star is around 9.6 times as massive as the Sun, and has an average of 4.5 times its radius. It is 5,800 times as luminous as the Sun, its energy emitted from its outer envelope at an effective temperature of 18,044 K. A Be star, Alpha Arae is surrounded by a dense equatorial disk of material in Keplerian (rather than uniform) rotation. The star is losing mass by a polar stellar wind with a terminal velocity of approximately 1,000 km/s. + +The third brightest star in Ara at magnitude 3.13 is Zeta Arae, an orange giant of spectral type K3III that is located 490 ± 10 light-years from Earth. Around 7–8 times as massive as the Sun, it has swollen to a diameter around 114 times that of the Sun and is 3800 times as luminous. Were it not dimmer by intervening interstellar dust, it would be significantly brighter at magnitude 2.11. + +Delta Arae is a blue-white main sequence star of spectral type B8Vn and magnitude 3.6, 198 ± 4 light-years from Earth. It is around 3.56 times as massive as the Sun. + +Epsilon1 Arae is an orange giant of apparent magnitude 4.1, 360 ± 10 light-years distant from Earth. It is around 74% more massive than the Sun. At an age of about 1.7 billion years, the outer envelope of the star has expanded to almost 34 times the Sun's radius. + +Eta Arae is an orange giant of apparent magnitude 3.76, located 299 ± 5 light-years distant from Earth. Estimated to be around five billion years old, it has reached the giant star stage of its evolution. With 1.12 times the mass of the Sun, it has an outer envelope that has expanded to 40 times the Sun's radius. The star is now spinning so slowly that it takes more than eleven years to complete a single rotation. + +GX 339-4 (V821 Arae) is a moderately strong variable galactic low-mass X-ray binary (LMXB) source and black-hole candidate that flares from time to time. From spectroscopic measurements, the mass of the black-hole was found to be at least of 5.8 solar masses. + +Exoplanets have been discovered in seven star systems in the constellation. Mu Arae (Cervantes) is a sunlike star that hosts four planets. HD 152079 is a sunlike star with a jupiter-like planet with an orbital period of 2097 ± 930 days. HD 154672 is an ageing sunlike star with a Hot Jupiter. HD 154857 is a sunlike star with one confirmed and one suspected planet. HD 156411 is a star hotter and larger than the sun with a gas giant planet in orbit. Gliese 674 is a nearby red dwarf star with a planet. Gliese 676 is a binary star system composed of two red dwarves with four planets. + +Deep-sky objects + +The northwest corner of Ara is crossed by the galactic plane of the Milky Way and contains several open clusters (notably NGC 6200) and diffuse nebulae (including the bright cluster/nebula pair NGC 6188 and NGC 6193).

It is bordered by Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, Texas to the southwest, and Oklahoma to the west. Its name is from the Osage language, a Dhegiha Siouan language, and referred to their relatives, the Quapaw people. The state's diverse geography ranges from the mountainous regions of the Ozark and Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta. + +Arkansas is the 29th largest by area and the 34th most populous state, with a population of just over 3 million at the 2020 census. The capital and most populous city is Little Rock, in the central part of the state, a hub for transportation, business, culture, and government. The northwestern corner of the state, including the Fayetteville–Springdale–Rogers Metropolitan Area and Fort Smith metropolitan area, is a population, education, and economic center. The largest city in the state's eastern part is Jonesboro. The largest city in the state's southeastern part is Pine Bluff. + +Previously part of French Louisiana and the Louisiana Purchase, the Territory of Arkansas was admitted to the Union as the 25th state on June 15, 1836. Much of the Delta had been developed for cotton plantations, and landowners there largely depended on enslaved African Americans' labor. In 1861, Arkansas seceded from the United States and joined the Confederate States of America during the American Civil War. On returning to the Union in 1868, Arkansas continued to suffer economically, due to its overreliance on the large-scale plantation economy. Cotton remained the leading commodity crop, and the cotton market declined. Because farmers and businessmen did not diversify and there was little industrial investment, the state fell behind in economic opportunity. In the late 19th century, the state instituted various Jim Crow laws to disenfranchise and segregate the African-American population. White interests dominated Arkansas's politics, with disenfranchisement of African Americans and refusal to reapportion the legislature; only after the federal legislation passed were more African Americans able to vote. During the civil rights movement of the 1950s and 1960s, Arkansas and particularly Little Rock were major battlegrounds for efforts to integrate schools. + +Following World War II in the 1940s, Arkansas began to diversify its economy and see prosperity. During the 1960s, the state became the base of the Walmart corporation, the world's largest company by revenue, headquartered in Bentonville. In the 21st century, Arkansas's economy is based on service industries, aircraft, poultry, steel, and tourism, along with important commodity crops of cotton, soybeans and rice. + +Arkansas's culture is observable in museums, theaters, novels, television shows, restaurants, and athletic venues across the state. Notable people from the state include politician and educational advocate William Fulbright; former president Bill Clinton, who also served as the 40th and 42nd governor of Arkansas; general Wesley Clark, former NATO Supreme Allied Commander; Walmart founder and magnate Sam Walton; singer-songwriters Johnny Cash, Charlie Rich, Jimmy Driftwood, and Glen Campbell; actor-filmmaker Billy Bob Thornton; poet C. D. Wright; physicist William L. McMillan, a pioneer in superconductor research; poet laureate Maya Angelou; Douglas MacArthur; musician Al Green; actor Alan Ladd; basketball player Scottie Pippen; singer Ne-Yo; Chelsea Clinton; actress Sheryl Underwood; and author John Grisham. + +Etymology + +The name Arkansas initially applied to the Arkansas River. It derives from a French term, Arcansas, their plural term for their transliteration of akansa, an Algonquian term for the Quapaw people. These were a Dhegiha Siouan-speaking people who settled in Arkansas around the 13th century. Kansa is likely also the root term for Kansas, which was named after the related Kaw people. + +The name has been pronounced and spelled in a variety of ways. In 1881, the state legislature defined the official pronunciation of Arkansas as having the final "s" be silent (as it would be in French). A dispute had arisen between the state's two senators over the pronunciation issue. One favored (), the other (). + +In 2007, the state legislature passed a non-binding resolution declaring that the possessive form of the state's name is Arkansas's, which the state government has increasingly followed. + +History + +Early history + +Before European settlement of North America, Arkansas, was inhabited by indigenous peoples for thousands of years. The Caddo, Osage, and Quapaw peoples encountered European explorers. The first of these Europeans was Spanish explorer Hernando de Soto in 1541, who crossed the Mississippi and marched across central Arkansas and the Ozark Mountains. After finding nothing he considered of value and encountering native resistance the entire way, he and his men returned to the Mississippi River where de Soto fell ill. From his deathbed he ordered his men to massacre all the men of the nearby village of Anilco, who he feared had been plotting with a powerful polity down the Mississippi River, Quigualtam. His men obeyed and did not stop with the men, but were said to have massacred women and children as well. He died the following day in what is believed to be the vicinity of modern-day McArthur, Arkansas, in May 1542. His body was weighted down with sand and he was consigned to a watery grave in the Mississippi River under cover of darkness by his men. De Soto had attempted to deceive the native population into thinking he was an immortal deity, sun of the sun, in order to forestall attack by outraged Native Americans on his by then weakened and bedraggled army. In order to keep the ruse up, his men informed the locals that de Soto had ascended into the sky. His will at the time of his death listed "four Indian slaves, three horses and 700 hogs" which were auctioned off. The starving men, who had been living off maize stolen from natives, immediately started butchering the hogs and later, commanded by former aide-de-camp Moscoso, attempted an overland return to Mexico. They made it as far as Texas before running into territory too dry for maize farming and too thinly populated to sustain themselves by stealing food from the locals. The expedition promptly backtracked to Arkansas. After building a small fleet of boats they then headed down the Mississippi River and eventually on to Mexico by water. + +Later explorers included the French Jacques Marquette and Louis Jolliet in 1673, and Frenchmen Robert La Salle and Henri de Tonti in 1681. Tonti established Arkansas Post at a Quapaw village in 1686, making it the first European settlement in the territory. The early Spanish or French explorers of the state gave it its name, which is probably a phonetic spelling of the Illinois tribe's name for the Quapaw people, who lived downriver from them. The name Arkansas has been pronounced and spelled in a variety of fashions. The region was organized as the Territory of Arkansaw on July 4, 1819, with the territory admitted to the United States as the state of Arkansas on June 15, 1836. The name was historically , , and several other variants. Historically and modernly, the people of Arkansas call themselves either "Arkansans" or "Arkansawyers". In 1881, the Arkansas General Assembly passed Arkansas Code 1-4-105 (official text): +Whereas, confusion of practice has arisen in the pronunciation of the name of our state and it is deemed important that the true pronunciation should be determined for use in oral official proceedings. +And, whereas, the matter has been thoroughly investigated by the State Historical Society and the Eclectic Society of Little Rock, which have agreed upon the correct pronunciation as derived from history, and the early usage of the American immigrants. +Be it therefore resolved by both houses of the General Assembly, that the only true pronunciation of the name of the state, in the opinion of this body, is that received by the French from the native Indians and committed to writing in the French word representing the sound. It should be pronounced in three (3) syllables, with the final "s" silent, the "a" in each syllable with the Italian sound, and the accent on the first and last syllables. The pronunciation with the accent on the second syllable with the sound of "a" in "man" and the sounding of the terminal "s" is an innovation to be discouraged. +Citizens of the state of Kansas often pronounce the Arkansas River as , in a manner similar to the common pronunciation of the name of their state. + +Settlers, such as fur trappers, moved to Arkansas in the early 18th century. These people used Arkansas Post as a home base and entrepôt. During the colonial period, Arkansas changed hands between France and Spain following the Seven Years' War, although neither showed interest in the remote settlement of Arkansas Post. In April 1783, Arkansas saw its only battle of the American Revolutionary War, a brief siege of the post by British Captain James Colbert with the assistance of the Choctaw and Chickasaw. + +Purchase and statehood + +Napoleon Bonaparte sold French Louisiana to the United States in 1803, including all of Arkansas, in a transaction known today as the Louisiana Purchase. French soldiers remained as a garrison at Arkansas Post. Following the purchase, the balanced give-and-take relationship between settlers and Native Americans began to change all along the frontier, including in Arkansas. Following a controversy over allowing slavery in the territory, the Territory of Arkansas was organized on July 4, 1819. Gradual emancipation in Arkansas was struck down by one vote, the Speaker of the House Henry Clay, allowing Arkansas to organize as a slave territory. + +Slavery became a wedge issue in Arkansas, forming a geographic divide that remained for decades. Owners and operators of the cotton plantation economy in southeast Arkansas firmly supported slavery, as they perceived slave labor as the best or "only" economically viable method of harvesting their commodity crops. The "hill country" of northwest Arkansas was unable to grow cotton and relied on a cash-scarce, subsistence farming economy. + +As European Americans settled throughout the East Coast and into the Midwest, in the 1830s the United States government forced the removal of many Native American tribes to Arkansas and Indian Territory west of the Mississippi River. + +Additional Native American removals began in earnest during the territorial period, with final Quapaw removal complete by 1833 as they were pushed into Indian Territory. The capital was relocated from Arkansas Post to Little Rock in 1821, during the territorial period. + +When Arkansas applied for statehood, the slavery issue was again raised in Washington, D.C. Congress eventually approved the Arkansas Constitution after a 25-hour session, admitting Arkansas on June 15, 1836, as the 25th state and the 13th slave state, having a population of about 60,000. Arkansas struggled with taxation to support its new state government, a problem made worse by a state banking scandal and worse yet by the Panic of 1837. + +Civil War and Reconstruction + +In early antebellum Arkansas, the southeast Arkansas slave-based economy developed rapidly. On the eve of the American Civil War in 1860, enslaved African Americans numbered 111,115 people, just over 25% of the state's population. A plantation system based largely on cotton agriculture developed that, after the war, kept the state and region behind the nation for decades. The wealth developed among planters of southeast Arkansas caused a political rift between the northwest and southeast. + +Many politicians were elected to office from the Family, the Southern rights political force in antebellum Arkansas. Residents generally wanted to avoid a civil war. When the Gulf states seceded in early 1861, delegates to a convention called to determine whether Arkansas should secede referred the question back to the voters for a referendum to be held in August. Arkansas did not secede until Abraham Lincoln demanded Arkansas troops be sent to Fort Sumter to quell the rebellion there. On May 6, the members of the state convention, having been recalled by the convention president, voted to terminate Arkansas's membership in the Union and join the Confederate States of America. + +Arkansas held a very important position for the Rebels, maintaining control of the Mississippi River and surrounding Southern states. The bloody Battle of Wilson's Creek just across the border in Missouri shocked many Arkansans who thought the war would be a quick and decisive Southern victory. Battles early in the war took place in northwest Arkansas, including the Battle of Cane Hill, Battle of Pea Ridge, and Battle of Prairie Grove. Union general Samuel Curtis swept across the state to Helena in the Delta in 1862. Little Rock was captured the following year. The government shifted the state Confederate capital to Hot Springs, and then again to Washington from 1863 to 1865, for the remainder of the war. Throughout the state, guerrilla warfare ravaged the countryside and destroyed cities. Passion for the Confederate cause waned after implementation of programs such as the draft, high taxes, and martial law. + +Under the Military Reconstruction Act, Congress declared Arkansas restored to the Union in June 1868, after the Legislature accepted the 14th Amendment. The Republican-controlled reconstruction legislature established universal male suffrage (though temporarily disfranchising former Confederate Army officers, who were all Democrats), a public education system for blacks and whites, and passed general issues to improve the state and help more of the population. The State soon came under control of the Radical Republicans and Unionists, and led by Governor Powell Clayton, they presided over a time of great upheaval as Confederate sympathizers and the Ku Klux Klan fought the new developments, particularly voting rights for African Americans. + +End of Reconstruction and late 19th century +In 1874, the Brooks-Baxter War, a political struggle between factions of the Republican Party shook Little Rock and the state governorship. It was settled only when President Ulysses S. Grant ordered Joseph Brooks to disperse his militant supporters. + +Following the Brooks-Baxter War, a new state constitution was ratified, re-enfranchising former Confederates and effectively bringing an end to Reconstruction. + +In 1881, the Arkansas state legislature enacted a bill that adopted an official pronunciation of the state's name, to combat a controversy then simmering. (See Law and Government below.) + +After Reconstruction, the state began to receive more immigrants and migrants. Chinese, Italian, and Syrian men were recruited for farm labor in the developing Delta region. None of these nationalities stayed long at farm labor; the Chinese especially, as they quickly became small merchants in towns around the Delta. Many Chinese became such successful merchants in small towns that they were able to educate their children at college. + +Construction of railroads enabled more farmers to get their products to market. It also brought new development into different parts of the state, including the Ozarks, where some areas were developed as resorts. In a few years at the end of the 19th century, for instance, Eureka Springs in Carroll County grew to 10,000 people, rapidly becoming a tourist destination and the fourth-largest city of the state. It featured newly constructed, elegant resort hotels and spas planned around its natural springs, considered to have healthful properties. The town's attractions included horse racing and other entertainment. It appealed to a wide variety of classes, becoming almost as popular as Hot Springs. + +Rise of the Jim Crow laws and early 20th century + +In the late 1880s, the worsening agricultural depression catalyzed Populist and third party movements, leading to interracial coalitions. Struggling to stay in power, in the 1890s the Democrats in Arkansas followed other Southern states in passing legislation and constitutional amendments that disfranchised blacks and poor whites. In 1891 state legislators passed a requirement for a literacy test, knowing it would exclude many blacks and whites. At the time, more than 25% of the population could neither read nor write. In 1892, they amended the state constitution to require a poll tax and more complex residency requirements, both of which adversely affected poor people and sharecroppers, forcing most blacks and many poor whites from voter rolls. + +By 1900 the Democratic Party expanded use of the white primary in county and state elections, further denying blacks a part in the political process. Only in the primary was there any competition among candidates, as Democrats held all the power. The state was a Democratic one-party state for decades, until after passage of the federal Civil Rights Act of 1964 and Voting Rights Act of 1965 to enforce constitutional rights. + +Between 1905 and 1911, Arkansas began to receive a small immigration of German, Slovak, and Scots-Irish from Europe. The German and Slovak peoples settled in the eastern part of the state known as the Prairie, and the Irish founded small communities in the southeast part of the state. The Germans were mostly Lutheran and the Slovaks were primarily Catholic. The Irish were mostly Protestant from Ulster, of Scots and Northern Borders descent. Some early 20th-century immigration included people from eastern Europe. Together, these immigrants made the Delta more diverse than the rest of the state. In the same years, some black migrants moved into the area because of opportunities to develop the bottomlands and own their own property. + +Black sharecroppers began to try to organize a farmers' union after World WarI. They were seeking better conditions of payment and accounting from white landowners of the area cotton plantations. Whites resisted any change and often tried to break up their meetings. On September 30, 1919, two white men, including a local deputy, tried to break up a meeting of black sharecroppers who were trying to organize a farmers' union. After a white deputy was killed in a confrontation with guards at the meeting, word spread to town and around the area. Hundreds of whites from Phillips and neighboring areas rushed to suppress the blacks, and started attacking blacks at large. Governor Charles Hillman Brough requested federal troops to stop what was called the Elaine massacre. White mobs spread throughout the county, killing an estimated 237 blacks before most of the violence was suppressed after October 1. Five whites also died in the incident. The governor accompanied the troops to the scene; President Woodrow Wilson had approved their use. + +The Great Mississippi Flood of 1927 flooded the areas along the Ouachita Rivers along with many other rivers. + +Based on the order of President Franklin D. Roosevelt given shortly after Imperial Japan's attack on Pearl Harbor, nearly 16,000 Japanese Americans were forcibly removed from the West Coast of the United States and incarcerated in two internment camps in the Arkansas Delta. The Rohwer Camp in Desha County operated from September 1942 to November 1945 and at its peak interned 8,475 prisoners. The Jerome War Relocation Center in Drew County operated from October 1942 to June 1944 and held about 8,000. + +Fall of segregation +After the Supreme Court ruled segregation in public schools unconstitutional in Brown v. Board of Education of Topeka, Kansas (1954), some students worked to integrate schools in the state. The Little Rock Nine brought Arkansas to national attention in 1957 when the federal government had to intervene to protect African-American students trying to integrate a high school in the capital. Governor Orval Faubus had ordered the Arkansas National Guard to help segregationists prevent nine African-American students from enrolling at Little Rock's Central High School. After attempting three times to contact Faubus, President Dwight D. Eisenhower sent 1,000 troops from the active-duty 101st Airborne Division to escort and protect the African-American students as they entered school on September 25, 1957. In defiance of federal court orders to integrate, the governor and city of Little Rock decided to close the high schools for the remainder of the school year. By the fall of 1959, the Little Rock high schools were completely integrated. + +Geography + +Boundaries +Arkansas borders Louisiana to the south, Texas to the southwest, Oklahoma to the west, Missouri to the north, and Tennessee and Mississippi to the east. The United States Census Bureau classifies Arkansas as a southern state, sub-categorized among the West South Central States. The Mississippi River forms most of its eastern border, except in Clay and Greene counties, where the St. Francis River forms the western boundary of the Missouri Bootheel, and in many places where the channel of the Mississippi has meandered (or been straightened by man) from its original 1836 course. + +Terrain + +Arkansas can generally be split into two halves, the highlands in the northwest and the lowlands of the southeast. The highlands are part of the Southern Interior Highlands, including The Ozarks and the Ouachita Mountains. The southern lowlands include the Gulf Coastal Plain and the Arkansas Delta. This split can yield to a regional division into northwest, southwest, northeast, southeast, and central Arkansas. These regions are broad and not defined along county lines. Arkansas has seven distinct natural regions: the Ozark Mountains, Ouachita Mountains, Arkansas River Valley, Gulf Coastal Plain, Crowley's Ridge, and the Arkansas Delta, with Central Arkansas sometimes included as a blend of multiple regions. + +The southeastern part of Arkansas along the Mississippi Alluvial Plain is sometimes called the Arkansas Delta. This region is a flat landscape of rich alluvial soils formed by repeated flooding of the adjacent Mississippi. Farther from the river, in the southeastern part of the state, the Grand Prairie has a more undulating landscape. Both are fertile agricultural areas. The Delta region is bisected by a geological formation known as Crowley's Ridge. A narrow band of rolling hills, Crowley's Ridge rises above the surrounding alluvial plain and underlies many of eastern Arkansas's major towns. + +Northwest Arkansas is part of the Ozark Plateau including the Ozark Mountains, to the south are the Ouachita Mountains, and these regions are divided by the Arkansas River; the southern and eastern parts of Arkansas are called the Lowlands. These mountain ranges are part of the U.S. Interior Highlands region, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains. The state's highest point is Mount Magazine in the Ouachita Mountains, which is above sea level. + +Arkansas is home to many caves, such as Blanchard Springs Caverns. The State Archeologist has catalogued more than 43,000 Native American living, hunting and tool-making sites, many of them Pre-Columbian burial mounds and rock shelters. Crater of Diamonds State Park near Murfreesboro is the world's only diamond-bearing site accessible to the public for digging. Arkansas is home to a dozen Wilderness Areas totaling . These areas are set aside for outdoor recreation and are open to hunting, fishing, hiking, and primitive camping. No mechanized vehicles nor developed campgrounds are allowed in these areas. + +Hydrology + +Arkansas has many rivers, lakes, and reservoirs within or along its borders. Major tributaries to the Mississippi River include the Arkansas River, the White River, and the St. Francis River. The Arkansas is fed by the Mulberry and Fourche LaFave Rivers in the Arkansas River Valley, which is also home to Lake Dardanelle. The Buffalo, Little Red, Black and Cache Rivers are all tributaries to the White River, which also empties into the Mississippi. Bayou Bartholomew and the Saline, Little Missouri, and Caddo Rivers are all tributaries to the Ouachita River in south Arkansas, which empties into the Mississippi in Louisiana. The Red River briefly forms the state's boundary with Texas. Arkansas has few natural lakes and many reservoirs, such as Bull Shoals Lake, Lake Ouachita, Greers Ferry Lake, Millwood Lake, Beaver Lake, Norfork Lake, DeGray Lake, and Lake Conway. + +Flora and fauna + +Arkansas's temperate deciduous forest is divided into three broad ecoregions: the Ozark, Ouachita-Appalachian Forests, the Mississippi Alluvial and Southeast USA Coastal Plains, and the Southeastern USA Plains. The state is further divided into seven subregions: the Arkansas Valley, Boston Mountains, Mississippi Alluvial Plain, Mississippi Valley Loess Plain, Ozark Highlands, Ouachita Mountains, and the South Central Plains. A 2010 United States Forest Service survey determined of Arkansas's land is forestland, or 56% of the state's total area. Dominant species in Arkansas's forests include Quercus (oak), Carya (hickory), Pinus echinata (shortleaf pine) and Pinus taeda (loblolly pine). + +Arkansas's plant life varies with its climate and elevation. The pine belt stretching from the Arkansas delta to Texas consists of dense oak-hickory-pine growth. Lumbering and paper milling activity is active throughout the region. In eastern Arkansas, one can find Taxodium (cypress), Quercus nigra (water oaks), and hickories with their roots submerged in the Mississippi Valley bayous indicative of the deep south. Nearby Crowley's Ridge is the only home of the tulip tree in the state, and generally hosts more northeastern plant life such as the beech tree. The northwestern highlands are covered in an oak-hickory mixture, with Ozark white cedars, cornus (dogwoods), and Cercis canadensis (redbuds) also present. The higher peaks in the Arkansas River Valley play host to scores of ferns, including the Physematium scopulinum and Adiantum (maidenhair fern) on Mount Magazine. Arkansas wildlife is famous for the white-tailed deer, elk, and bald eagle. The white-tailed deer is the official state mammal. + +Climate + +Arkansas generally has a humid subtropical climate. While not bordering the Gulf of Mexico, Arkansas, is still close enough to the warm, large body of water for it to influence the weather in the state. Generally, Arkansas, has hot, humid summers and slightly drier, mild to cool winters. In Little Rock, the daily high temperatures average around with lows around in July. In January highs average around and lows around . In Siloam Springs in the northwest part of the state, the average high and low temperatures in July are and in January the average high and low are . Annual precipitation throughout the state averages between about ; it is somewhat wetter in the south and drier in the northern part of the state. Snowfall is infrequent but most common in the northern half of the state. The half of the state south of Little Rock is apter to see ice storms. Arkansas's record high is at Ozark on August 10, 1936; the record low is at Gravette, on February 13, 1905. + +Arkansas is known for extreme weather and frequent storms. A typical year brings thunderstorms, tornadoes, hail, snow and ice storms. Between both the Great Plains and the Gulf States, Arkansas, receives around 60 days of thunderstorms. Arkansas is located in Tornado Alley, and as a result, a few of the most destructive tornadoes in U.S. history have struck the state. While sufficiently far from the coast to avoid a direct hit from a hurricane, Arkansas can often get the remnants of a tropical system, which dumps tremendous amounts of rain in a short time and often spawns smaller tornadoes. + +Cities and towns + +Little Rock has been Arkansas's capital city since 1821 when it replaced Arkansas Post as the capital of the Territory of Arkansas. The state capitol was moved to Hot Springs and later Washington during the American Civil War when the Union armies threatened the city in 1862, and state government did not return to Little Rock until after the war ended. Today, the Little Rock–North Little Rock–Conway metropolitan area is the largest in the state, with a population of 724,385 in 2013. + +The Fayetteville–Springdale–Rogers Metropolitan Area is the second-largest metropolitan area in Arkansas, growing at the fastest rate due to the influx of businesses and the growth of the University of Arkansas and Walmart. + +The state has eight cities with populations above 50,000 (based on 2010 census). In descending order of size, they are Little Rock, Fort Smith, Fayetteville, Springdale, Jonesboro, North Little Rock, Conway, and Rogers. Of these, only Fort Smith and Jonesboro are outside the two largest metropolitan areas. Other cities in Arkansas include Pine Bluff, Crossett, Bryant, Lake Village, Hot Springs, Bentonville, Texarkana, Sherwood, Jacksonville, Russellville, Bella Vista, West Memphis, Paragould, Cabot, Searcy, Van Buren, El Dorado, Blytheville, Harrison, Dumas, Rison, Warren, and Mountain Home. + +Demographics + +Population + +The United States Census Bureau estimated that the population of Arkansas was 3,017,804 on July 1, 2019, a 3.49% increase since the 2010 United States census. At the 2020 U.S. census, Arkansas had a resident population of 3,011,524. + +From fewer than 15,000 in 1820, Arkansas's population grew to 52,240 during a special census in 1835, far exceeding the 40,000 required to apply for statehood. Following statehood in 1836, the population doubled each decade until the 1870 census conducted following the American Civil War. The state recorded growth in each successive decade, although it gradually slowed in the 20th century. + +It recorded population losses in the 1950 and 1960 censuses. This outmigration was a result of multiple factors, including farm mechanization, decreasing labor demand, and young educated people leaving the state due to a lack of non-farming industry in the state. Arkansas again began to grow, recording positive growth rates ever since and exceeding two million by the 1980 census. Arkansas's rate of change, age distributions, and gender distributions mirror national averages. Minority group data also approximates national averages. There are fewer people in Arkansas of Hispanic or Latino origin than the national average. The center of population of Arkansas for 2000 was located in Perry County, near Nogal. + +According to HUD's 2022 Annual Homeless Assessment Report, there were an estimated 2,459 homeless people in Arkansas. + +Race and ethnicity +Per the 2019 census estimates, Arkansas was 72.0% non-Hispanic white, 15.4% Black or African American, 0.5% American Indian and Alaska Native, 1.5% Asian, 0.4% Native Hawaiian or other Pacific Islander, 0.1% some other race, 2.4% two or more races, and 7.7% Hispanic or Latin American of any race. In 2011, the state was 80.1% white (74.2% non-Hispanic white), 15.6% Black or African American, 0.9% American Indian and Alaska Native, 1.3% Asian, and 1.8% from two or more races. Hispanics or Latinos of any race made up 6.6% of the population. As of 2011, 39.0% of Arkansas's population younger than age1 were minorities. + +European Americans have a strong presence in the northwestern Ozarks and the central part of the state. African Americans live mainly in the southern and eastern parts of the state. Arkansans of Irish, English and German ancestry are mostly found in the far northwestern Ozarks near the Missouri border. Ancestors of the Irish in the Ozarks were chiefly Scots-Irish, Protestants from Northern Ireland, the Scottish lowlands and northern England part of the largest group of immigrants from Great Britain and Ireland before the American Revolution. English and Scots-Irish immigrants settled throughout the back country of the South and in the more mountainous areas. Americans of English stock are found throughout the state. + +A 2010 survey of the principal ancestries of Arkansas's residents revealed the following: 15.5% African American, 12.3% Irish, 11.5% German, 11.0% American, 10.1% English, 4.7% Mexican, 2.1% French, 1.7% Scottish, 1.7% Dutch, 1.6% Italian, and 1.4% Scots-Irish. + +Most people identifying as "American" are of English descent or Scots-Irish descent. Their families have been in the state so long, in many cases since before statehood, that they choose to identify simply as having American ancestry or do not in fact know their ancestry. Their ancestry primarily goes back to the original 13 colonies and for this reason many of them today simply claim American ancestry. Many people who identify as of Irish descent are in fact of Scots-Irish descent. + +According to the American Immigration Council, in 2015, the top countries of origin for Arkansas' immigrants were Mexico, El Salvador, India, Vietnam, and Guatemala. + +According to the 2006–2008 American Community Survey, 93.8% of Arkansas's population (over the age of five) spoke only English at home. About 4.5% of the state's population spoke Spanish at home. About 0.7% of the state's population spoke another Indo-European language. About 0.8% of the state's population spoke an Asian language, and 0.2% spoke other languages. + +Religion + +Like most other Southern states, Arkansas is part of the Bible Belt and predominantly Protestant. The largest denominations by number of adherents in 2010 were the Southern Baptist Convention with 661,382; the United Methodist Church with 158,574; non-denominational Evangelical Protestants with 129,638; the Catholic Church with 122,662; and the Church of Jesus Christ of Latter-day Saints with 31,254. Some residents of the state have other religions, such as Islam, Judaism, Wicca/Paganism, Hinduism, Buddhism, and some have no religious affiliation. + +In 2014, the Pew Research Center determined that 79% of the population was Christian, dominated by evangelicals in the Southern Baptist and independent Baptist churches. In contrast with many other states, the Catholic Church as of 2014 was not the largest Christian denomination in Arkansas. Of the unaffiliated population, 2% were atheist in 2014. By 2020, the Public Religion Research Institute determined 71% of the population was Christian. Arkansas continued to be dominated by evangelicals, followed by mainline Protestants and historically black or African American churches. + +Economy + +Once a state with a cashless society in the uplands and plantation agriculture in the lowlands, Arkansas's economy has evolved and diversified. The state's gross domestic product (GDP) was $119billion in 2015. Six Fortune 500 companies are based in Arkansas, including the world's #1 retailer, Walmart; Tyson Foods, J.B. Hunt, Dillard's, Murphy USA, and Windstream are also headquartered in the state. The per capita personal income in 2015 was $39,107, ranking 45th in the nation. The median household income from 2011 to 2015 was $41,371, ranking 49th in the nation. The state's agriculture outputs are poultry and eggs, soybeans, sorghum, cattle, cotton, rice, hogs, and milk. Its industrial outputs are food processing, electric equipment, fabricated metal products, machinery, and paper products. Arkansas's mines produce natural gas, oil, crushed stone, bromine, and vanadium. According to CNBC, Arkansas is the 20th-best state for business, with the 2nd-lowest cost of doing business, 5th-lowest cost of living, 11th-best workforce, 20th-best economic climate, 28th-best-educated workforce, 31st-best infrastructure and the 32nd-friendliest regulatory environment. Arkansas gained 12 spots in the best state for business rankings since 2011. As of 2014, it was the most affordable state to live in. + +As of June 2021, the state's unemployment rate was 4.4%; the preliminary rate for November 2021 is 3.4%. + +Industry and commerce +Arkansas's earliest industries were fur trading and agriculture, with development of cotton plantations in the areas near the Mississippi River. They were dependent on slave labor through the American Civil War. + +Today only about three percent of the population are employed in the agricultural sector, it remains a major part of the state's economy, ranking 13th in the nation in the value of products sold. Arkansas is the nation's largest producer of rice, broilers, and turkeys, and ranks in the top three for cotton, pullets, and aquaculture (catfish). Forestry remains strong in the Arkansas Timberlands, and the state ranks fourth nationally and first in the South in softwood lumber production. Automobile parts manufacturers have opened factories in eastern Arkansas to support auto plants in other states. Bauxite was formerly a large part of the state's economy, mined mostly around Saline County. + +Tourism is also very important to the Arkansas economy; the official state nickname "The Natural State" was created for state tourism advertising in the 1970s, and is still used to this day. The state maintains 52 state parks and the National Park Service maintains seven properties in Arkansas. The completion of the William Jefferson Clinton Presidential Library in Little Rock has drawn many visitors to the city and revitalized the nearby River Market District. Many cities also hold festivals, which draw tourists to Arkansas culture, such as The Bradley County Pink Tomato Festival in Warren, King Biscuit Blues Festival, Ozark Folk Festival, Toad Suck Daze, and Tontitown Grape Festival. + +Transportation + +Transportation in Arkansas is overseen by the Arkansas Department of Transportation (ArDOT), headquartered in Little Rock. Several main corridors pass through Little Rock, including Interstate30 (I-30) and I-40 (the nation's 3rd-busiest trucking corridor). Arkansas first designated a state highway system in 1924, and first numbered its roads in 1926. Arkansas had one of the first paved roads, the Dollarway Road, and one of the first members of the Interstate Highway System. The state maintains a large system of state highways today, in addition to eight Interstates and 20 U.S. Routes. + +In northeast Arkansas, I-55 travels north from Memphis to Missouri, with a new spur to Jonesboro (I-555). Northwest Arkansas is served by the segment of I-49 from Fort Smith to the beginning of the Bella Vista Bypass. This segment of I-49 currently follows mostly the same route as the former section of I-540 that extended north of I-40. The state also has the 13th largest state highway system in the nation. + +Arkansas is served by of railroad track divided among twenty-six railroad companies including three Class I railroads. Freight railroads are concentrated in southeast Arkansas to serve the industries in the region. The Texas Eagle, an Amtrak passenger train, serves five stations in the state Walnut Ridge, Little Rock, Malvern, Arkadelphia, and Texarkana. + +Arkansas also benefits from the use of its rivers for commerce. The Mississippi River and Arkansas River are both major rivers. The United States Army Corps of Engineers maintains the McClellan-Kerr Arkansas River Navigation System, allowing barge traffic up the Arkansas River to the Port of Catoosa in Tulsa, Oklahoma. + +There are four airports with commercial service: Clinton National Airport (formerly Little Rock National Airport or Adams Field), Northwest Arkansas Regional Airport, Fort Smith Regional Airport, and Texarkana Regional Airport, with dozens of smaller airports in the state. + +Intercity bus services across the state are provided by Flixbus, Greyhound Lines, and Jefferson Lines. + +Public transit and community transport services for the elderly or those with developmental disabilities are provided by agencies such as the Central Arkansas Transit Authority and the Ozark Regional Transit, organizations that are part of the Arkansas Transit Association. + +Government + +As with the federal government of the United States, political power in Arkansas is divided into three branches: executive, legislative, and judicial. Each officer's term is four years long. Office holders are term-limited to two full terms plus any partial terms before the first full term. + +Executive + +The governor of Arkansas is Sarah Huckabee Sanders, a Republican, who was inaugurated on January 10, 2023. The six other elected executive positions in Arkansas are lieutenant governor, secretary of state, attorney general, treasurer, auditor, and land commissioner. The governor also appoints the leaders of various state boards, committees, and departments. Arkansas governors served two-year terms until a referendum lengthened the term to four years, effective with the 1986 election. Individuals elected to these offices are limited to a lifetime total of two four-year terms per office. + +In Arkansas, the lieutenant governor is elected separately from the governor and thus can be from a different political party. + +Legislative + +The Arkansas General Assembly is the state's bicameral bodies of legislators, composed of the Senate and House of Representatives. The Senate contains 35 members from districts of approximately equal population. These districts are redrawn decennially with each US census, and in election years ending in "2", the entire body is put up for reelection. Following the election, half of the seats are designated as two-year seats and are up for reelection again in two years, these "half-terms" do not count against a legislator's term limits. The remaining half serve a full four-year term. This staggers elections such that half the body is up for reelection every two years and allows for complete body turnover following redistricting. Arkansas voters elected a 21–14 Republican majority in the Senate in 2012. Arkansas House members can serve a maximum of three two-year terms. House districts are redistricted by the Arkansas Board of Apportionment. In the 2012 elections, Republicans gained a 51–49 majority in the House of Representatives. + +The Republican Party majority status in the Arkansas State House of Representatives after the 2012 elections, is the party's first since 1874. Arkansas was the last state of the old Confederacy to not have Republican control of either chamber of its house since the American Civil War. + +Following the term limits changes, studies have shown that lobbyists have become less influential in state politics. Legislative staff, not subject to term limits, have acquired additional power and influence due to the high rate of elected official turnover. + +Judicial + +Arkansas's judicial branch has five court systems: Arkansas Supreme Court, Arkansas Court of Appeals, Circuit Courts, District Courts and City Courts. + +Most cases begin in district court, which is subdivided into state district court and local district court. State district courts exercise district-wide jurisdiction over the districts created by the General Assembly, and local district courts are presided over by part-time judges who may privately practice law. 25 state district court judges preside over 15 districts, with more districts created in 2013 and 2017. There are 28 judicial circuits of Circuit Court, with each contains five subdivisions: criminal, civil, probate, domestic relations, and juvenile court. The jurisdiction of the Arkansas Court of Appeals is determined by the Arkansas Supreme Court, and there is no right of appeal from the Court of Appeals to the high court. The Arkansas Supreme Court can review Court of Appeals cases upon application by either a party to the litigation, upon request by the Court of Appeals, or if the Arkansas Supreme Court feels the case should have been initially assigned to it. The twelve judges of the Arkansas Court of Appeals are elected from judicial districts to renewable six-year terms. + +The Arkansas Supreme Court is the court of last resort in the state, composed of seven justices elected to eight-year terms. Established by the Arkansas Constitution in 1836, the court's decisions can be appealed to only the Supreme Court of the United States. + +Federal +Both Arkansas's U.S. senators, John Boozman and Tom Cotton, are Republicans. The state has four seats in U.S. House of Representatives. All four seats are held by Republicans: Rick Crawford (1st district), French Hill (2nd district), Steve Womack (3rd district), and Bruce Westerman (4th district). + +Politics + +Arkansas governor Bill Clinton brought national attention to the state with a long speech at the 1988 Democratic National Convention endorsing Michael Dukakis. Some journalists suggested the speech was a threat to his ambitions; Clinton defined it "a comedy of error, just one of those fluky things". He won the Democratic nomination for president in 1992. Presenting himself as a "New Democrat" and using incumbent George H. W. Bush's broken promise against him, Clinton won the 1992 presidential election with 43.0% of the vote to Bush's 37.5% and independent billionaire Ross Perot's 18.9%. + +Most Republican strength traditionally lay mainly in the northwestern part of the state, particularly Fort Smith and Bentonville, as well as North Central Arkansas around the Mountain Home area. In the latter area, Republicans have been known to get 90% or more of the vote, while the rest of the state was more Democratic. After 2010, Republican strength expanded further to the Northeast and Southwest and into the Little Rock suburbs. The Democrats are mostly concentrated to central Little Rock, the Mississippi Delta, the Pine Bluff area, and the areas around the southern border with Louisiana. + +Arkansas has elected only three Republicans to the U.S. Senate since Reconstruction: Tim Hutchinson, who was defeated after one term by Mark Pryor; John Boozman, who defeated incumbent Blanche Lincoln; and Tom Cotton, who defeated Pryor in 2014. Before 2013, the General Assembly had not been controlled by the Republican Party since Reconstruction, with the GOP holding a 51-seat majority in the state House and a 21-seat (of 35) in the state Senate following victories in 2012. Arkansas was one of just three states among the states of the former Confederacy that sent two Democrats to the U.S. Senate (the others being Florida and Virginia) for any period during the first decade of the 21st century. + +In 2010, Republicans captured three of the state's four seats in the U.S. House of Representatives. In 2012, they won election to all four House seats. Arkansas held the distinction of having a U.S. House delegation composed entirely of military veterans (Rick Crawford, Army; Tim Griffin, Army Reserve; Steve Womack, Army National Guard; Tom Cotton, Army). When Pryor was defeated in 2014, the entire congressional delegation was in GOP hands for the first time since Reconstruction. + +Reflecting the state's large evangelical population, Arkansas has a strong social conservative bent. In the aftermath of the landmark Supreme Court decision Dobbs v. Jackson Women's Health Organization, Arkansas became one of nine states where abortion is banned. Under the Arkansas Constitution, Arkansas is a right to work state. Its voters passed a ban on same-sex marriage in 2004, with 75% voting yes, although that ban has been inactive since the Supreme Court protected same-sex marriage in Obergefell v. Hodges. + +Arkansas retains the death penalty. Authorized methods of execution include the Electric chair. + +Military +The Strategic Air Command facility of Little Rock Air Force Base was one of eighteen silos in the command of the 308th Strategic Missile Wing (308th SMW), specifically one of the nine silos within its 374th Strategic Missile Squadron (374th SMS). The squadron was responsible for Launch Complex 374–7, site of the 1980 explosion of a TitanII Intercontinental Ballistic Missile (ICBM) in Damascus, Arkansas. + +Taxation +Taxes are collected by the Arkansas Department of Finance and Administration. + +Health + +As of 2012, Arkansas, as with many Southern states, has a high incidence of premature death, infant mortality, cardiovascular deaths, and occupational fatalities compared to the rest of the United States. The state is tied for 43rd with New York in percentage of adults who regularly exercise. Arkansas is usually ranked as one of the least healthy states due to high obesity, smoking, and sedentary lifestyle rates, but according to a Gallup poll, Arkansas made the most immediate progress in reducing its number of uninsured residents after the Affordable Care Act passed. The percentage of uninsured in Arkansas dropped from 22.5 in 2013 to 12.4 in August 2014. + +The Arkansas Clean Indoor Air Act, a statewide smoking ban excluding bars and some restaurants, went into effect in 2006. + +Healthcare in Arkansas is provided by a network of hospitals as members of the Arkansas Hospital Association. Major institutions with multiple branches include Baptist Health, Community Health Systems, and HealthSouth. The University of Arkansas for Medical Sciences (UAMS) in Little Rock operates the UAMS Medical Center, a teaching hospital ranked as high performing nationally in cancer and nephrology. The pediatric division of UAMS Medical Center is known as Arkansas Children's Hospital, nationally ranked in pediatric cardiology and heart surgery. Together, these two institutions are the state's only Level I trauma centers. + +Education + +Arkansas has 1,064 state-funded kindergartens, elementary, junior and senior high schools. + +The state supports a network of public universities and colleges, including two major university systems: Arkansas State University System and University of Arkansas System. The University of Arkansas, flagship campus of the University of Arkansas System in Fayetteville was ranked #63 among public schools in the nation by U.S. News & World Report. Other public institutions include University of Arkansas at Pine Bluff, Arkansas Tech University, Henderson State University, Southern Arkansas University, and University of Central Arkansas across the state. It is also home to 11 private colleges and universities including Hendrix College, one of the nation's top 100 liberal arts colleges, according to U.S. News & World Report. + +In the 1920s the state required all children to attend public schools. The school year was set at 131 days, although some areas were unable to meet that requirement. + +Generally prohibited in the West at large, school corporal punishment is not unusual in Arkansas, with 20,083 public school students paddled at least one time, according to government data for the 2011–12 school year. The rate of corporal punishment in public schools is higher only in Mississippi. + +Media + +As of 2010 many Arkansas local newspapers are owned by WEHCO Media, Alabama-based Lancaster Management, Kentucky-based Paxton Media Group, Missouri-based Rust Communications, Nevada-based Stephens Media, and New York-based GateHouse Media. + +Culture + +The culture of Arkansas includes distinct cuisine, dialect, and traditional festivals. Sports are also very important to the culture, including football, baseball, basketball, hunting, and fishing. Perhaps the best-known aspect of Arkansas's culture is the stereotype that its citizens are shiftless hillbillies. The reputation began when early explorers characterized the state as a savage wilderness full of outlaws and thieves. The most enduring icon of Arkansas's hillbilly reputation is The Arkansas Traveller, a painted depiction of a folk tale from the 1840s. Though intended to represent the divide between rich southeastern plantation Arkansas planters and the poor northwestern hill country, the meaning was twisted to represent a Northerner lost in the Ozarks on a white horse asking a backwoods Arkansan for directions. The state also suffers from the racial stigma common to former Confederate states, with historical events such as the Little Rock Nine adding to Arkansas's enduring image. + +Art and history museums display pieces of cultural value for Arkansans and tourists to enjoy. Crystal Bridges Museum of American Art in Bentonville was visited by 604,000 people in 2012, its first year. The museum includes walking trails and educational opportunities in addition to displaying over 450 works covering five centuries of American art. Several historic town sites have been restored as Arkansas state parks, including Historic Washington State Park, Powhatan Historic State Park, and Davidsonville Historic State Park. + +Arkansas features a variety of native music across the state, ranging from the blues heritage of West Memphis, Pine Bluff, Helena–West Helena to rockabilly, bluegrass, and folk music from the Ozarks. Festivals such as the King Biscuit Blues Festival and Bikes, Blues, and BBQ pay homage to the history of blues in the state. The Ozark Folk Festival in Mountain View is a celebration of Ozark culture and often features folk and bluegrass musicians. Literature set in Arkansas such as I Know Why the Caged Bird Sings by Maya Angelou and A Painted House by John Grisham describe the culture at various time periods. + +Sports and recreation + +Sports have become an integral part of the culture of Arkansas, and her residents enjoy participating in and spectating various events throughout the year. + +Team sports and especially collegiate football are important to Arkansans. College football in Arkansas began from humble beginnings, when the University of Arkansas first fielded a team in 1894. Over the years, many Arkansans have looked to Arkansas Razorbacks football as the public image of the state. Although the University of Arkansas is based in Fayetteville, the Razorbacks have always played at least one game per season at War Memorial Stadium in Little Rock in an effort to keep fan support in central and south Arkansas. + +Arkansas State University became the second NCAA Division I Football Bowl Subdivision (FBS) (then known as Division I-A) team in the state in 1992 after playing in lower divisions for nearly two decades. The two schools have never played each other, due to the University of Arkansas's policy of not playing intrastate games. Two other campuses of the University of Arkansas System are Division I members. The University of Arkansas at Pine Bluff is a member of the Southwestern Athletic Conference, a league whose members all play football in the second-level Football Championship Subdivision (FCS). The University of Arkansas at Little Rock, known for sports purposes as Little Rock, joined the Ohio Valley Conference in 2022 after playing in the Sun Belt Conference; unlike many other OVC members, it does not field a football program. The state's other DivisionI member is the University of Central Arkansas (UCA), which joined the ASUN Conference in 2021 after leaving the FCS Southland Conference. Because the ASUN does not plan to start FCS football competition until at least 2022, UCA football is competing in the Western Athletic Conference as part of a formal football partnership between the two leagues. Seven of Arkansas's smaller colleges play in NCAA Division II, with six in the Great American Conference and one in the Lone Star Conference. Two other small Arkansas colleges compete in NCAA Division III, in which athletic scholarships are prohibited. High school football also began to grow in Arkansas in the early 20th century. + +Baseball runs deep in Arkansas and was popular before the state hosted Major League Baseball (MLB) spring training in Hot Springs from 1886 to the 1920s. Two minor league teams are based in the state. The Arkansas Travelers play at Dickey–Stephens Park in North Little Rock, and the Northwest Arkansas Naturals play in Arvest Ballpark in Springdale. Both teams compete in Double-A Central. + +Hunting continues in the state. The state created the Arkansas Game and Fish Commission in 1915 to regulate hunting. Today a significant portion of Arkansas's population participates in hunting duck in the Mississippi flyway and deer across the state. Ducks Unlimited has called Stuttgart, Arkansas, "the epicenter of the duck universe". Millions of acres of public land are available for both bow and modern gun hunters. + +Fishing has always been popular in Arkansas, and the sport and the state have benefited from the creation of reservoirs across the state. Following the completion of Norfork Dam, the Norfork Tailwater and the White River have become a destination for trout fishers. Several smaller retirement communities such as Bull Shoals, Hot Springs Village, and Fairfield Bay have flourished due to their position on a fishing lake. The National Park Service has preserved the Buffalo National River in its natural state and fly fishers visit it annually. + +Attractions + +Arkansas is home to many areas protected by the National Park System.

It represents a bird-of-paradise, and its name means "without feet" in Greek because the bird-of-paradise was once wrongly believed to lack feet. First depicted on a celestial globe by Petrus Plancius in 1598, it was charted on a star atlas by Johann Bayer in his 1603 Uranometria. The French explorer and astronomer Nicolas Louis de Lacaille charted and gave the brighter stars their Bayer designations in 1756. + +The five brightest stars are all reddish in hue. Shading the others at apparent magnitude 3.8 is Alpha Apodis, an orange giant that has around 48 times the diameter and 928 times the luminosity of the Sun. Marginally fainter is Gamma Apodis, another ageing giant star. Delta Apodis is a double star, the two components of which are 103 arcseconds apart and visible with the naked eye. Two star systems have been found to have planets. + +History + +Apus was one of twelve constellations published by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman who had sailed on the first Dutch trading expedition, known as the Eerste Schipvaart, to the East Indies. It first appeared on a 35-cm (14 in) diameter celestial globe published in 1598 in Amsterdam by Plancius with Jodocus Hondius. De Houtman included it in his southern star catalogue in 1603 under the Dutch name De Paradijs Voghel, "The Bird of Paradise", and Plancius called the constellation Paradysvogel Apis Indica; the first word is Dutch for "bird of paradise". Apis (Latin for "bee") is assumed to have been a typographical error for avis ("bird"). + +After its introduction on Plancius's globe, the constellation's first known appearance in a celestial atlas was in German cartographer Johann Bayer's Uranometria of 1603. Bayer called it Apis Indica while fellow astronomers Johannes Kepler and his son-in-law Jakob Bartsch called it Apus or Avis Indica. The name Apus is derived from the Greek apous, meaning "without feet". This referred to the Western misconception that the bird-of-paradise had no feet, which arose because the only specimens available in the West had their feet and wings removed. Such specimens began to arrive in Europe in 1522, when the survivors of Ferdinand Magellan's expedition brought them home. The constellation later lost some of its tail when Nicolas-Louis de Lacaille used those stars to establish Octans in the 1750s. + +Characteristics +Covering 206.3 square degrees and hence 0.5002% of the sky, Apus ranks 67th of the 88 modern constellations by area. Its position in the Southern Celestial Hemisphere means that the whole constellation is visible to observers south of 7°N. It is bordered by Ara, Triangulum Australe and Circinus to the north, Musca and Chamaeleon to the west, Octans to the south, and Pavo to the east. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "Aps". The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of six segments (illustrated in infobox). In the equatorial coordinate system, the right ascension coordinates of these borders lie between and , while the declination coordinates are between −67.48° and −83.12°. + +Features + +Stars + +Lacaille gave twelve stars Bayer designations, labelling them Alpha through to Kappa, including two stars next to each other as Delta and another two stars near each other as Kappa. Within the constellation's borders, there are 39 stars brighter than or equal to apparent magnitude 6.5. Beta, Gamma and Delta Apodis form a narrow triangle, with Alpha Apodis lying to the east. The five brightest stars are all red-tinged, which is unusual among constellations. + +Alpha Apodis is an orange giant of spectral type K3III located 430 ± 20 light-years away from Earth, with an apparent magnitude of 3.8. It spent much of its life as a blue-white (B-type) main sequence star before expanding, cooling and brightening as it used up its core hydrogen. It has swollen to 48 times the Sun's diameter, and shines with a luminosity approximately 928 times that of the Sun, with a surface temperature of 4312 K. Beta Apodis is an orange giant 149 ± 2 light-years away, with a magnitude of 4.2. It is around 1.84 times as massive as the Sun, with a surface temperature of 4677 K. Gamma Apodis is a yellow giant of spectral type G8III located 150 ± 4 light-years away, with a magnitude of 3.87. It is approximately 63 times as luminous the Sun, with a surface temperature of 5279 K. Delta Apodis is a double star, the two components of which are 103 arcseconds apart and visible through binoculars. Delta1 is a red giant star of spectral type M4III located 630 ± 30 light-years away. It is a semiregular variable that varies from magnitude +4.66 to +4.87, with pulsations of multiple periods of 68.0, 94.9 and 101.7 days. Delta2 is an orange giant star of spectral type K3III, located 550 ± 10 light-years away, with a magnitude of 5.3. The separate components can be resolved with the naked eye. + +The fifth-brightest star is Zeta Apodis at magnitude 4.8, a star that has swollen and cooled to become an orange giant of spectral type K1III, with a surface temperature of 4649 K and a luminosity 133 times that of the Sun. It is 300 ± 4 light-years distant. Near Zeta is Iota Apodis, a binary star system 1,040 ± 60 light-years distant, that is composed of two blue-white main sequence stars that orbit each other every 59.32 years. Of spectral types B9V and B9.5 V, they are both over three times as massive as the Sun. + +Eta Apodis is a white main sequence star located 140.8 ± 0.9 light-years distant. Of apparent magnitude 4.89, it is 1.77 times as massive, 15.5 times as luminous as the Sun and has 2.13 times its radius. Aged 250 ± 200 million years old, this star is emitting an excess of 24 μm infrared radiation, which may be caused by a debris disk of dust orbiting at a distance of more than 31 astronomical units from it. + +Theta Apodis is a cool red giant of spectral type M7 III located 350 ± 30 light-years distant. It shines with a luminosity approximately 3879 times that of the Sun and has a surface temperature of 3151 K. A semiregular variable, it varies by 0.56 magnitudes with a period of 119 days—or approximately 4 months. It is losing mass at the rate of times the mass of the Sun per year through its stellar wind. Dusty material ejected from this star is interacting with the surrounding interstellar medium, forming a bow shock as the star moves through the galaxy. NO Apodis is a red giant of spectral type M3III that varies between magnitudes 5.71 and 5.95. Located 780 ± 20 light-years distant, it shines with a luminosity estimated at 2059 times that of the Sun and has a surface temperature of 3568 K. S Apodis is a rare R Coronae Borealis variable, an extremely hydrogen-deficient supergiant thought to have arisen as the result of the merger of two white dwarfs; fewer than 100 have been discovered as of 2012. It has a baseline magnitude of 9.7. R Apodis is a star that was given a variable star designation, yet has turned out not to be variable. Of magnitude 5.3, it is another orange giant. + +Two star systems have had exoplanets discovered by doppler spectroscopy, and the substellar companion of a third star system—the sunlike star HD 131664—has since been found to be a brown dwarf with a calculated mass of the companion to 23 times that of Jupiter (minimum of 18 and maximum of 49 Jovian masses). HD 134606 is a yellow sunlike star of spectral type G6IV that has begun expanding and cooling off the main sequence. Three planets orbit it with periods of 12, 59.5 and 459 days, successively larger as they are further away from the star. HD 137388 is another star—of spectral type K2IV—that is cooler than the Sun and has begun cooling off the main sequence. Around 47% as luminous and 88% as massive as the Sun, with 85% of its diameter, it is thought to be around 7.4 ± 3.9 billion years old. It has a planet that is 79 times as massive as the Earth and orbits its sun every 330 days at an average distance of 0.89 astronomical units (AU). + +Deep-sky objects + +The Milky Way covers much of the constellation's area. Of the deep-sky objects in Apus, there are two prominent globular clusters—NGC 6101 and IC 4499—and a large faint nebula that covers several degrees east of Beta and Gamma Apodis. NGC 6101 is a globular cluster of apparent magnitude 9.2 located around 50,000 light-years distant from Earth, which is around 160 light-years across. Around 13 billion years old, it contains a high concentration of massive bright stars known as blue stragglers, thought to be the result of two stars merging. IC 4499 is a loose globular cluster in the medium-far galactic halo; its apparent magnitude is 10.6. + +The galaxies in the constellation are faint. IC 4633 is a very faint spiral galaxy surrounded by a vast amount of Milky Way line-of-sight integrated flux nebulae—large faint clouds thought to be lit by large numbers of stars. + +See also + IAU-recognized constellations + +Notes + +References + +External links + + The Deep Photographic Guide to the Constellations: Apus + The clickable Apus + + +Southern constellations +Constellations listed by Petrus Plancius +Dutch celestial cartography in the Age of Discovery +Astronomy in the Dutch Republic +1590s in the Dutch Republic +Abadan ( Ābādān, ) is a city in the Central District of Abadan County, Khuzestan province, Iran, and serves as both capital of the county and of the district. The city is in the southwest of the county. It lies on Abadan Island ( long, 3–19 km or 2–12 miles wide). The island is bounded in the west by the Arvand waterway and to the east by the Bahmanshir outlet of the Karun River (the Arvand Rood), from the Persian Gulf, near the Iran–Iraq border. Abadan is 140 km from the provincial capital city of Ahvaz. + +Etymology +The earliest mention of the island of Abadan, if not the port itself, is found in works of the geographer Marcian, who renders the name "Apphadana". Earlier, the classical geographer Ptolemy notes "Apphana" as an island off the mouth of the Tigris (which is where the modern Island of Abadan is located). An etymology for this name is presented by B. Farahvashi to be derived from the Persian word "ab" (water) and the root "pā" (guard, watch) thus "coastguard station"). + +In Islamic times, a pseudo-etymology was produced by the historian Ahmad ibn Yahya al-Baladhuri (d. 892) quoting a folk story that the town was presumably founded by one "Abbad bin Hosayn" from the Arabian Tribe of Banu Tamim, who established a garrison there during the governorship of Hajjaj in the Ummayad period. + +In the subsequent centuries, the Persian version of the name had begun to come into general use before it was adopted by official decree in 1935. + +Population + +The civilian population of the city dropped close to zero during the eight years of the Iran–Iraq War (1980–1988). The 1986 census recorded only 6 people. In 1991, 84,774 had returned to live in the city. By 2001, the population had jumped to 206,073, and it was 217,988, in 48,061 households, according to 2006 census. The following census in 2011 counted 212,744 people in 55,318 households. The latest census in 2016 showed a population of 231,476 people in 66,470 households. Abadan Refinery is one of the largest in the world. + +Only 9% of managers (of the oil company) were from Khuzestan. The proportion of natives of Tehran, the Caspian, Azerbaijan, and Kurdistan rose from 4% of blue collar workers to 22% of white collar workers to 45% of managers, thus Arabic-speakers were concentrated on the lower rungs of the work force, managers tended to be brought in from some distance. There is also a single Armenian church in the centre of the city, Saint Garapet church. + +History +Abadan is thought to have been further developed into a major port city under the Abbasids' rule. The city was then a commercial source of salt and woven mats. The siltation of the river delta forced the town further away from water; In the 14th century, however, Ibn Battutah described Abadan just as a small port in a flat salty plain. Politically, Abadan was often the subject of dispute between the nearby states. In 1847, Persia acquired it from the Ottoman Empire in which state Abadan has remained since. From the 17th century onward, the island of Abadan was part of the lands of the Arab Ka'ab (Bani Kaab) tribe. One section of the tribe, Mohaysen, had its headquarters at Mohammara (now Khorramshahr), until the removal of Shaikh Khaz'al Khan in 1924. + +It was not until the 20th century that rich oil fields were discovered in the area. On 16 July 1909, after secret negotiation with the British consul, Percy Cox, assisted by Arnold Wilson, and Sheik Khaz'al agreed to a rental agreement for the island, including Abadan. The Sheik continued to administer the island until 1924. The Anglo-Persian Oil Company built their first pipeline terminus oil refinery in Abadan, starting in 1909 and completing it in 1912, with oil flowing by August 1912 (see Abadan Refinery). Refinery throughput numbers rose from 33,000 tons in 1912–1913 to 4,338,000 tons in 1931. By 1938, it was the largest in the world. + +During World War II, Abadan was the site of brief combat between Iranian forces and British and Indian troops during the Anglo-Soviet invasion of Iran. Alanbrooke wrote in August 1942 that everything depends on the oil from Abadan, as "if we lost Persian oil we inevitably lost Egypt, command of the Indian Ocean, and endangered the whole India Burma situation, which "could not be made good from America because of the shortage of tankers ...". Later, Abadan was a major logistics centre for Lend-Lease aircraft being sent to the Soviet Union by the United States. + +In 1951, Iran nationalised all oil properties and refining ground to a stop on the island. Rioting broke out in Abadan, after the government had decided to nationalise the oil facilities, and three British workers were killed. It was not until 1954 that a settlement was reached, which allowed a consortium of international oil companies to manage the production and refining on the island. That continued until 1973, when the NIOC took over all facilities. After the total nationalisation, Iran focused on supplying oil domestically and built a pipeline from Abadan to Tehran. + +Abadan was not a major cultural or religious centre, but it played an important role in the Islamic Revolution. On 19 August 1978, the anniversary of the US-backed coup d'état that had overthrown the nationalist and popular Iranian prime minister, Mohammed Mossadegh, the Cinema Rex, a movie theatre in Abadan, was set ablaze. The Cinema Rex Fire caused 430 deaths, but more importantly, it was another event that kept the Islamic Revolution moving ahead. At the time, there was much confusion and misinformation about the perpetrators of the incident. The public largely put the blame on the local police chief and also the Shah and SAVAK. The reformist Sobh-e Emrooz newspaper in one of its editorials revealed that the Cinema Rex was burned down by radical Islamists. The newspaper was shut down immediately afterwards. Over time, the true culprits, radical Islamists, were apprehended, and the logic behind this act was revealed, as they were trying both to foment the general public to distrust the government even more, and perceived cinema as a link to the Americans. The fire was one of four during a short period in August, with other fires in Mashhad, Rizaiya, and Shiraz. +In September 1980, Abadan was almost overrun during a surprise attack on Khuzestan by Iraq, marking the beginning of the Iran–Iraq War. For 12 months, Abadan was besieged, but never captured, by Iraqi forces, and in September 1981, the Iranians broke the siege of Abadan. Much of the city, including the oil refinery, which was the world's largest refinery with a capacity of 628,000 barrels per day, was badly damaged or destroyed by the siege and by bombing. Prior to the war, the city's civilian population was about 300,000, but at the war's end nearly the entire populace had sought refuge elsewhere in Iran. + +After the war, the biggest concern was the rebuilding of Abadan's oil refinery, as it was operating at 10% of capacity due to damage. In 1993, the refinery began limited operation and the port reopened. By 1997, the refinery reached the same rate of production as before the war. Recently, Abadan has been the site of major labour activity as workers at the oil refineries in the city have staged walkouts and strikes to protest non-payment of wages and the political situation in the country. + +Recent events +To honor the 100th anniversary of the refining of oil in Abadan, city officials are planning an oil museum. The Abadan oil refinery was featured on the reverse side of Iran's 100-rial banknotes printed in 1965 and from 1971 to 1973. Abadan today has been declared as a free zone city. The healthy relationship between Iran and Iraq has become one of the transit cities connecting both countries through a 40-minute drive. + +Geography + +Climate +The climate in Abadan is arid (Köppen climate classification BWh) and similar to Baghdad's, but slightly hotter due to Abadan's lower latitude. Summers are dry and extremely hot, with temperatures above almost daily and temperatures above can be almost common. Abadan is notably one of the few hottest populated places on earth and experiences a few sand and dust storms per year. Winters are mildly wet and spring-like, though subject to cold spells with night frost. However, winters in Abadan have no snow. Winter temperatures are around . The world's highest unconfirmed temperature was a temperature flare up during a heat burst in June 1967, with a temperature of . The lowest recorded temperature in the city range is . which was recorded on 20 January 1964 and 3 February 1967 while the highest is , recorded on 11 July 1951, 9 August 1981 and 5 August 2022. + +Economics and education +The Abadan Institute of Technology was established in Abadan in 1939. The school specialized in engineering and petroleum chemistry, and was designed to train staff for the refinery in town. The school's name has since changed several times, but since 1989 has been considered a branch campus of the Petroleum University of Technology, centred in Tehran. Abadan University of Medical Sciences, It was founded by Ministry of Health and Medical Education in September 1941 as a Nursing Faculty and in 2012 it became an independent faculty of medical school. Program study of this school is similar to curriculum that applies most Iranian medical faculties. + +Abadan was chosen for constructing a refinery because of its strategic position and proximity to other resources. The Abadan Refinery construction project started in 1909 and its operation began in 1962 by a production capacity of 2500 barrels per day. + +There is an international airport in Abadan. It is represented by the IATA airport code ABD. +There is a large amount of external investment from East Asian countries that are building oil refineries and developing a lot of real estate. + +Today, Abadan is known for its lively fish market where locals buy fresh catch of the day used in the many delicious seafood dishes of the city.

His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens has been described as the "single greatest victory ever achieved over disease". For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. + +He also discovered the enzyme lysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus lysodeikticus, later renamed Micrococcus luteus. + +Fleming was knighted for his scientific achievements in 1944. In 1999, he was named in Time magazine's list of the 100 Most Important People of the 20th century. In 2002, he was chosen in the BBC's television poll for determining the 100 Greatest Britons, and in 2009, he was also voted third "greatest Scot" in an opinion poll conducted by STV, behind only Robert Burns and William Wallace. + +Early life and education +Born on 6 August 1881 at Lochfield farm near Darvel, in Ayrshire, Scotland, Alexander Fleming was the third of four children of farmer Hugh Fleming (1816–1888) and Grace Stirling Morton (1848–1928), the daughter of a neighbouring farmer. Hugh Fleming had four surviving children from his first marriage. He was 59 at the time of his second marriage to Grace, and died when Alexander was seven. + +Fleming went to Loudoun Moor School and Darvel School, and earned a two-year scholarship to Kilmarnock Academy before moving to London, where he attended the Royal Polytechnic Institution. After working in a shipping office for four years, the twenty-year-old Alexander Fleming inherited some money from an uncle, John Fleming. His elder brother, Tom, was already a physician and suggested to him that he should follow the same career, and so in 1903, the younger Alexander enrolled at St Mary's Hospital Medical School in Paddington (now part of Imperial College London); he qualified with an MBBS degree from the school with distinction in 1906. + +Fleming, who was a private in the London Scottish Regiment of the Volunteer Force from 1900 to 1914, had been a member of the rifle club at the medical school. The captain of the club, wishing to retain Fleming in the team, suggested that he join the research department at St Mary's, where he became assistant bacteriologist to Sir Almroth Wright, a pioneer in vaccine therapy and immunology. In 1908, he gained a BSc degree with gold medal in Bacteriology, and became a lecturer at St Mary's until 1914. + +Commissioned lieutenant in 1914 and promoted captain in 1917, Fleming served throughout World War I in the Royal Army Medical Corps, and was Mentioned in Dispatches. He and many of his colleagues worked in battlefield hospitals at the Western Front in France. In 1918 he returned to St Mary's Hospital, where he was elected Professor of Bacteriology of the University of London in 1928. In 1951 he was elected the Rector of the University of Edinburgh for a term of three years. + +Scientific contributions + +Antiseptics + +During World War I, Fleming with Leonard Colebrook and Sir Almroth Wright joined the war efforts and practically moved the entire Inoculation Department of St Mary's to the British military hospital at Boulogne-sur-Mer. Serving as a temporary lieutenant of the Royal Army Medical Corps, he witnessed the death of many soldiers from sepsis resulting from infected wounds. Antiseptics, which were used at the time to treat infected wounds, he observed, often worsened the injuries. In an article published in the medical journal The Lancet in 1917, he described an ingenious experiment, which he was able to conduct as a result of his own glassblowing skills, in which he explained why antiseptics were killing more soldiers than infection itself during the war. Antiseptics worked well on the surface, but deep wounds tended to shelter anaerobic bacteria from the antiseptic agent, and antiseptics seemed to remove beneficial agents produced that protected the patients in these cases at least as well as they removed bacteria, and did nothing to remove the bacteria that were out of reach. Wright strongly supported Fleming's findings, but despite this, most army physicians over the course of the war continued to use antiseptics even in cases where this worsened the condition of the patients. + +Discovery of lysozyme + +At St Mary's Hospital, Fleming continued his investigations into bacteria culture and antibacterial substances. As his research scholar at the time V. D. Allison recalled, Fleming was not a tidy researcher and usually expected unusual bacterial growths in his culture plates. Fleming had teased Allison of his "excessive tidiness in the laboratory", and Allison rightly attributed such untidiness as the success of Fleming's experiments, and said, "[If] he had been as tidy as he thought I was, he would not have made his two great discoveries." + +In late 1921, while he was maintaining agar plates for bacteria, he found that one of the plates was contaminated with bacteria from the air. When he added nasal mucus, he found that the mucus inhibited the bacterial growth. Surrounding the mucus area was a clear transparent circle (1 cm from the mucus), indicating the killing zone of bacteria, followed by a glassy and translucent ring beyond which was an opaque area indicating normal bacterial growth. In the next test, he used bacteria maintained in saline that formed a yellow suspension. Within two minutes of adding fresh mucus, the yellow saline turned completely clear. He extended his tests using tears, which were contributed by his co-workers. As Allison reminisced, saying, "For the next five or six weeks, our tears were the source of supply for this extraordinary phenomenon. Many were the lemons we used (after the failure of onions) to produce a flow of tears... The demand by us for tears was so great, that laboratory attendants were pressed into service, receiving threepence for each contribution." + +His further tests with sputum, cartilage, blood, semen, ovarian cyst fluid, pus, and egg white showed that the bactericidal agent was present in all of these. He reported his discovery before the Medical Research Club in December and before the Royal Society the next year but failed to stir any interest, as Allison recollected:I was present at this [Medical Research Club] meeting as Fleming's guest. His paper describing his discovery was received with no questions asked and no discussion, which was most unusual and an indication that it was considered to be of no importance. The following year he read a paper on the subject before the Royal Society, Burlington House, Piccadilly and he and I gave a demonstration of our work. Again with one exception little comment or attention was paid to it. + +Reporting in the 1 May 1922 issue of the Proceedings of the Royal Society B: Biological Sciences under the title "On a remarkable bacteriolytic element found in tissues and secretions", Fleming wrote:In this communication I wish to draw attention to a substance present in the tissues and secretions of the body, which is capable of rapidly dissolving certain bacteria. As this substance has properties akin to those of ferments I have called it a "Lysozyme", and shall refer to it by this name throughout the communication. The lysozyme was first noticed during some investigations made on a patient suffering from acute coryza.This was the first recorded discovery of lysozyme. With Allison, he published further studies on lysozyme in October issue of the British Journal of Experimental Pathology the same year. Although he was able to obtain larger amounts of lysozyme from egg whites, the enzyme was only effective against small counts of harmless bacteria, and therefore had little therapeutic potential. This indicates one of the major differences between pathogenic and harmless bacteria. + +Described in the original publication, "a patient suffering from acute coryza" was later identified as Fleming himself. His research notebook dated 21 November 1921 showed a sketch of the culture plate with a small note: “Staphyloid coccus from A.F.'s nose." He also identified the bacterium present in the nasal mucus as Micrococcus Lysodeikticus, giving the species name (meaning "lysis indicator" for its susceptibility to lysozymal activity). The species was reassigned as Micrococcus luteus in 1972. The "Fleming strain" (NCTC2665) of this bacterium has become a model in different biological studies. The importance of lysozyme was not recognised, and Fleming was well aware of this, in his presidential address at the Royal Society of Medicine meeting on 18 October 1932, he said:I choose lysozyme as the subject for this address for two reasons, firstly because I have a fatherly interest in the name, and, secondly, because its importance in connection with natural immunity does not seem to be generally appreciated. In his Nobel lecture on 11 December 1945, he briefly mentioned lysozyme, saying, "Penicillin was not the first antibiotic I happened to discover." It was only towards the end of the 20th century that the true importance of Fleming's discovery in immunology was realised as lysozyme became the first antimicrobial protein discovered that constitute part of our innate immunity. + +Discovery of penicillin + +Experiment +By 1927, Fleming had been investigating the properties of staphylococci. He was already well known from his earlier work, and had developed a reputation as a brilliant researcher. In 1928, he studied the variation of Staphylococcus aureus grown under natural condition, after the work of Joseph Warwick Bigger, who discovered that the bacterium could grow into a variety of types (strains). On 3 September 1928, Fleming returned to his laboratory having spent a holiday with his family at Suffolk. Before leaving for his holiday, he inoculated staphylococci on culture plates and left them on a bench in a corner of his laboratory. On his return, Fleming noticed that one culture was contaminated with a fungus, and that the colonies of staphylococci immediately surrounding the fungus had been destroyed, whereas other staphylococci colonies farther away were normal, famously remarking "That's funny". Fleming showed the contaminated culture to his former assistant Merlin Pryce, who reminded him, "That's how you discovered lysozyme." He identified the mould as being from the genus Penicillium. He suspected it to be P. chrysogenum, but a colleague Charles J. La Touche identified it as P. rubrum. (It was later corrected as P. notatum and then officially accepted as P. chrysogenum; in 2011, it was resolved as P. rubens.) + +The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room, which was directly below Fleming's. + +Fleming grew the mould in a pure culture and found that the culture broth contained an antibacterial substance. He investigated its anti-bacterial effect on many organisms, and noticed that it affected bacteria such as staphylococci and many other Gram-positive pathogens that cause scarlet fever, pneumonia, meningitis and diphtheria, but not typhoid fever or paratyphoid fever, which are caused by Gram-negative bacteria, for which he was seeking a cure at the time. It also affected Neisseria gonorrhoeae, which causes gonorrhoea, although this bacterium is Gram-negative. After some months of calling it "mould juice" or "the inhibitor", he gave the name penicillin on 7 March 1929 for the antibacterial substance present in the mould. + +Reception and publication +Fleming presented his discovery on 13 February 1929 before the Medical Research Club. His talk on "A medium for the isolation of Pfeiffer's bacillus" did not receive any particular attention or comment. Henry Dale, the then Director of National Institute for Medical Research and chair of the meeting, much later reminisced that he did not even sense any striking point of importance in Fleming's speech. Fleming published his discovery in 1929 in the British Journal of Experimental Pathology, but little attention was paid to the article. His problem was the difficulty of producing penicillin in large amounts, and moreover, isolation of the main compound. Even with the help of Harold Raistrick and his team of biochemists at the London School of Hygiene and Tropical Medicine, chemical purification was futile. "As a result, penicillin languished largely forgotten in the 1930s", as Milton Wainwright described. + +As late as in 1936, there was no appreciation for penicillin. When Fleming talked of its medical importance at the Second International Congress of Microbiology held in London, no one believed him. As Allison, his companion in both the Medical Research Club and international congress meeting, remarked the two occasions:[Fleming at the Medical Research Club meeting] suggested the possible value of penicillin for the treatment of infection in man. Again there was a total lack of interest and no discussion. Fleming was keenly disappointed, but worse was to follow. He read a paper on his work on penicillin at a meeting of the International Congress of Microbiology, attended by the foremost bacteriologists from all over the world. There was no support for his views on its possible future value for the prevention and treatment of human infections and discussion was minimal. Fleming bore these disappointments stoically, but they did not alter his views or deter him from continuing his investigation of penicillin.In 1941, the British Medical Journal reported that "[Penicillin] does not appear to have been considered as possibly useful from any other point of view." + +Purification and stabilisation + +In Oxford, Ernst Boris Chain and Edward Abraham were studying the molecular structure of the antibiotic. Abraham was the first to propose the correct structure of penicillin. Shortly after the team published its first results in 1940, Fleming telephoned Howard Florey, Chain's head of department, to say that he would be visiting within the next few days. When Chain heard that Fleming was coming, he remarked "Good God! I thought he was dead." + +Norman Heatley suggested transferring the active ingredient of penicillin back into water by changing its acidity. This produced enough of the drug to begin testing on animals. There were many more people involved in the Oxford team, and at one point the entire Sir William Dunn School of Pathology was involved in its production. After the team had developed a method of purifying penicillin to an effective first stable form in 1940, several clinical trials ensued, and their amazing success inspired the team to develop methods for mass production and mass distribution in 1945. + +Fleming was modest about his part in the development of penicillin, describing his fame as the "Fleming Myth" and he praised Florey and Chain for transforming the laboratory curiosity into a practical drug. Fleming was the first to discover the properties of the active substance, giving him the privilege of naming it: penicillin. He also kept, grew, and distributed the original mould for twelve years, and continued until 1940 to try to get help from any chemist who had enough skill to make penicillin. Sir Henry Harris summed up the process in 1998 as: "Without Fleming, no Chain; without Chain, no Florey; without Florey, no Heatley; without Heatley, no penicillin." The discovery of penicillin and its subsequent development as a prescription drug mark the start of modern antibiotics. + +Medical use and mass production +In his first clinical trial, Fleming treated his research scholar Stuart Craddock who had developed severe infection of the nasal antrum (sinusitis). The treatment started on 9 January 1929 but without any effect. It probably was due to the fact that the infection was with influenza bacillus (Haemophilus influenzae), the bacterium which he had found unsusceptible to penicillin. Fleming gave some of his original penicillin samples to his colleague-surgeon Arthur Dickson Wright for clinical test in 1928. Although Wright reportedly said that it "seemed to work satisfactorily", there are no records of its specific use. Cecil George Paine, a pathologist at the Royal Infirmary in Sheffield and former student of Fleming, was the first to use penicillin successfully for medical treatment. He cured eye infections (conjunctivitis) of one adult and three infants (neonatal conjunctivitis) on 25 November 1930. + +Fleming also successfully treated severe conjunctivitis in 1932. Keith Bernard Rogers, who had joined St Mary's as medical student in 1929, was captain of the London University rifle team and was about to participate in an inter-hospital rifle shooting competition when he developed conjunctivitis. Fleming applied his penicillin and cured Rogers before the competition. It is said that the "penicillin worked and the match was won." However, the report that "Keith was probably the first patient to be treated clinically with penicillin ointment" is no longer true as Paine's medical records showed up. + +There is a popular assertion both in popular and scientific literature that Fleming largely abandoned penicillin work in the early 1930s. In his review of André Maurois's The Life of Sir Alexander Fleming, Discoverer of Penicillin, William L. Kissick went so far as to say that "Fleming had abandoned penicillin in 1932... Although the recipient of many honors and the author of much scientific work, Sir Alexander Fleming does not appear to be an ideal subject for a biography." This is false, as Fleming continued to pursue penicillin research. As late as in 1939, Fleming's notebook shows attempts to make better penicillin production using different media. In 1941, he published a method for assessment of penicillin effectiveness. As to the chemical isolation and purification, Howard Florey and Ernst Boris Chain at the Radcliffe Infirmary in Oxford took up the research to mass-produce it, which they achieved with support from World War II military projects under the British and US governments. + +By mid-1942, the Oxford team produced the pure penicillin compound as yellow powder. In August 1942, Harry Lambert (an associate of Fleming's brother Robert) was admitted to St Mary's Hospital due to a life-threatening infection of the nervous system (streptococcal meningitis). Fleming treated him with sulphonamides, but Lambert's condition deteriorated. He tested the antibiotic susceptibility and found that his penicillin could kill the bacteria. He requested Florey for the isolated sample. Florey sent the incompletely purified sample, which Fleming immediately administered into Lambert's spinal canal. Lambert showed signs of improvement the very next day, and completely recovered within a week. Fleming published the clinical case in The Lancet in 1943. + +Upon this medical breakthrough, Allison informed the British Ministry of Health of the importance of penicillin and the need for mass production. The War Cabinet was convinced of the usefulness upon which Sir Cecil Weir, Director General of Equipment, called for a meeting on the mode of action on 28 September 1942. The Penicillin Committee was created on 5 April 1943. The committee consisted of Weir as chairman, Fleming, Florey, Sir Percival Hartley, Allison and representatives from pharmaceutical companies as members. The main goals were to produce penicillin rapidly in large quantities with collaboration of American companies, and to supply the drug exclusively for Allied armed forces. By D-Day in 1944, enough penicillin had been produced to treat all the wounded of the Allied troops. + +Antibiotic resistance + +Fleming also discovered very early that bacteria developed antibiotic resistance whenever too little penicillin was used or when it was used for too short a period. Almroth Wright had predicted antibiotic resistance even before it was noticed during experiments. Fleming cautioned about the use of penicillin in his many speeches around the world. On 26 June 1945, he made the following cautionary statements: "the microbes are educated to resist penicillin and a host of penicillin-fast organisms is bred out ... In such cases the thoughtless person playing with penicillin is morally responsible for the death of the man who finally succumbs to infection with the penicillin-resistant organism. I hope this evil can be averted." He cautioned not to use penicillin unless there was a properly diagnosed reason for it to be used, and that if it were used, never to use too little, or for too short a period, since these are the circumstances under which bacterial resistance to antibiotics develops. + +It had been experimentally shown in 1942 that S. aureus could develop penicillin resistance under prolonged exposure. Elaborating the possibility of penicillin resistance in clinical conditions in his Nobel Lecture, Fleming said:The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant.It was around that time that the first clinical case of penicillin resistance was reported. + +Personal life + +On 24 December 1915, Fleming married a trained nurse, Sarah Marion McElroy of Killala, County Mayo, Ireland. Their only child, Robert Fleming (1924–2015), became a general medical practitioner. After his first wife's death in 1949, Fleming married Amalia Koutsouri-Vourekas, a Greek colleague at St. Mary's, on 9 April 1953; she died in 1986. + +Fleming came from a Presbyterian background, while his first wife Sarah was a (lapsed) Roman Catholic. It is said that he was not particularly religious, and their son Robert was later received into the Anglican church, while still reportedly inheriting his two parents' fairly irreligious disposition. + +When Fleming learned of Robert D. Coghill and Andrew J. Moyer patenting the method of penicillin production in the United States in 1944, he was furious, and commented:I found penicillin and have given it free for the benefit of humanity. Why should it become a profit-making monopoly of manufacturers in another country?From 1921 until his death in 1955, Fleming owned a country home named "The Dhoon" in Barton Mills, Suffolk. + +Death +On 11 March 1955, Fleming died at his home in London of a heart attack. His ashes are buried in St Paul's Cathedral. + +Awards and legacy + +Fleming's discovery of penicillin changed the world of modern medicine by introducing the age of useful antibiotics; penicillin has saved, and is still saving, millions of people around the world. + +The laboratory at St Mary's Hospital where Fleming discovered penicillin is home to the Fleming Museum, a popular London attraction. His alma mater, St Mary's Hospital Medical School, merged with Imperial College London in 1988. The Sir Alexander Fleming Building on the South Kensington campus was opened in 1998, where his son Robert and his great-granddaughter Claire were presented to the Queen; it is now one of the main preclinical teaching sites of the Imperial College School of Medicine. + +His other alma mater, the Royal Polytechnic Institution (now the University of Westminster) has named one of its student halls of residence Alexander Fleming House, which is near to Old Street. + +Myths + +The Fleming myth +By 1942, penicillin, produced as pure compound, was still in short supply and not available for clinical use. When Fleming used the first few samples prepared by the Oxford team to treat Harry Lambert who had streptococcal meningitis, the successful treatment was a major news, particularly popularised in The Times. Wright was surprised to discover that Fleming and the Oxford team were not mentioned, though Oxford was attributed as the source of the drug. Wright wrote to the editor of The Times, which eagerly interviewed Fleming, but Florey prohibited the Oxford team from seeking media coverage. As a consequence, only Fleming was widely publicised in the media, which led to the misconception that he was entirely responsible for the discovery and development of the drug. Fleming himself referred to this incident as "the Fleming myth." + +The Churchills +The popular story of Winston Churchill's father paying for Fleming's education after Fleming's father saved young Winston from death is false. According to the biography, Penicillin Man: Alexander Fleming and the Antibiotic Revolution by Kevin Brown, Alexander Fleming, in a letter to his friend and colleague Andre Gratia, described this as "A wondrous fable." Nor did he save Winston Churchill himself during World War II. Churchill was saved by Lord Moran, using sulphonamides, since he had no experience with penicillin, when Churchill fell ill in Carthage in Tunisia in 1943. The Daily Telegraph and The Morning Post on 21 December 1943 wrote that he had been saved by penicillin. He was saved by the new sulphonamide drug sulphapyridine, known at the time under the research code M&B 693, discovered and produced by May & Baker Ltd, Dagenham, Essex – a subsidiary of the French group Rhône-Poulenc. In a subsequent radio broadcast, Churchill referred to the new drug as "This admirable M&B". It is highly probable that the correct information about the sulphonamide did not reach the newspapers because, since the original sulphonamide antibacterial, Prontosil, had been a discovery by the German laboratory Bayer, and as Britain was at war with Germany at the time, it was thought better to raise British morale by associating Churchill's cure with a British discovery, penicillin. + +See also + Fleming Prize Lecture + People on Scottish banknotes + +References + +Further reading + The Life Of Sir Alexander Fleming, Jonathan Cape, 1959.

Carnegie led the expansion of the American steel industry in the late 19th century and became one of the richest Americans in history. He became a leading philanthropist in the United States, Great Britain, and the British Empire. During the last 18 years of his life, he gave away around $350 million (roughly $ billion in ), almost 90 percent of his fortune, to charities, foundations and universities. His 1889 article proclaiming "The Gospel of Wealth" called on the rich to use their wealth to improve society, expressed support for progressive taxation and an estate tax, and stimulated a wave of philanthropy. + +Carnegie was born in Dunfermline, Scotland and emigrated to Pittsburgh, United States with his parents in 1848 at the age of 12. Carnegie started work as a telegrapher, and by the 1860s had investments in railroads, railroad sleeping cars, bridges, and oil derricks. He accumulated further wealth as a bond salesman, raising money for American enterprise in Europe. He built Pittsburgh's Carnegie Steel Company, which he sold to J. P. Morgan in 1901 for $303,450,000 (equal to $ today); it formed the basis of the U.S. Steel Corporation. After selling Carnegie Steel, he surpassed John D. Rockefeller as the richest American of the time. + +Carnegie devoted the remainder of his life to large-scale philanthropy, with special emphasis on building local libraries, world peace, education, and scientific research. He funded the Carnegie Hall in New York City, the Peace Palace in The Hague, founded the Carnegie Corporation of New York, Carnegie Endowment for International Peace, Carnegie Institution for Science, Carnegie Trust for the Universities of Scotland, Carnegie Hero Fund, Carnegie Mellon University, and the Carnegie Museums of Pittsburgh, among others. + +Biography + +Early life + +Andrew Carnegie was born to Margaret Morrison Carnegie and William Carnegie in Dunfermline, Scotland, in a typical weaver's cottage with only one main room, consisting of half the ground floor, which was shared with the neighboring weaver's family. The main room served as a living room, dining room and bedroom. He was named after his paternal grandfather. In 1836, the family moved to a larger house in Edgar Street (opposite Reid's Park), following the demand for more heavy damask, from which his father benefited. He was educated at the Free School in Dunfermline, a gift to the town from the philanthropist Adam Rolland of Gask. + +Carnegie's maternal uncle, Scottish political leader George Lauder Sr., deeply influenced him as a boy by introducing him to Robert Burns' writings and historical Scottish heroes such as Robert the Bruce, William Wallace, and Rob Roy. Lauder's son, also named George Lauder, grew up with Carnegie and became his business partner. When Carnegie was 12, his father had fallen on tough times as a handloom weaver. Making matters worse, the country was in starvation. His mother helped support the family by assisting her brother and by selling potted meats at her "sweetie shop", leaving her as the primary breadwinner. Struggling to make ends meet, the Carnegies then decided to borrow money from George Lauder, Sr. and move to Allegheny, Pennsylvania, in the United States in 1848 for the prospect of a better life. Carnegie's migration to America would be his second journey outside Dunfermline—the first being an outing to Edinburgh to see Queen Victoria. + +In September 1848, Carnegie arrived with his family in Allegheny. Carnegie's father struggled to sell his product on his own. Eventually, the father and son both received job offers at the same Scottish-owned cotton mill, Anchor Cotton Mills. Carnegie's first job in 1848 was as a bobbin boy, changing spools of thread in a cotton mill 12 hours a day, 6 days a week in a Pittsburgh cotton factory. His starting wage was $1.20 per week ($ by inflation). + +His father quit his position at the cotton mill soon after, returning to his loom and removing him as breadwinner once again. But Carnegie attracted the attention of John Hay, a Scottish manufacturer of bobbins, who offered him a job for $2.00 per week ($ by inflation). In his autobiography, Carnegie writes about the hardships he had to endure with this new job. + +Telegraph + +In 1849, Carnegie became a telegraph messenger boy in the Pittsburgh Office of the Ohio Telegraph Company, at $2.50 per week ($ by inflation) following the recommendation of his uncle. He was a hard worker and would memorize all of the locations of Pittsburgh's businesses and the faces of important men. He made many connections this way. He also paid close attention to his work and quickly learned to distinguish the different sounds the incoming telegraph signals produced. He developed the ability to translate signals by ear, without using the paper slip, and within a year was promoted to an operator. Carnegie's education and passion for reading were given a boost by Colonel James Anderson, who opened his personal library of 400 volumes to working boys each Saturday night. Carnegie was a consistent borrower and a "self-made man" in both his economic development and his intellectual and cultural development. He was so grateful to Colonel Anderson for the use of his library that he "resolved, if ever wealth came to me, [to see to it] that other poor boys might receive opportunities similar to those for which we were indebted to the nobleman". His capacity, his willingness for hard work, his perseverance and his alertness soon brought him opportunities. + +Railroads +Starting in 1853, when Carnegie was around 18 years old, Thomas A. Scott of the Pennsylvania Railroad employed him as a secretary/telegraph operator at a salary of $4.00 per week ($ by inflation). Carnegie accepted the job with the railroad as he saw more prospects for career growth and experience there than with the telegraph company. At age 24, Scott asked Carnegie if he could handle being superintendent of the Western Division of the Pennsylvania Railroad. On December 1, 1859, Carnegie officially became superintendent of the Western Division. Carnegie then hired his sixteen-year-old brother Tom to be his personal secretary and telegraph operator. Not only did Carnegie hire his brother, he also hired his cousin, Maria Hogan, who became the first female telegraph operator in the country. As superintendent Carnegie made a salary of $1500 a year ($ by inflation). His employment by the Pennsylvania Railroad would be vital to his later success. The railroads were the first big businesses in America, and the Pennsylvania was one of the largest of them all. Carnegie learned much about management and cost control during these years, and from Scott in particular. + +Scott also helped him with his first investments. Many of these were part of the corruption indulged in by Scott and the president of the Pennsylvania Railroad, John Edgar Thomson, which consisted of inside trading in companies that the railroad did business with, or payoffs made by contracting parties "as part of a quid pro quo". In 1855, Scott made it possible for Carnegie to invest $500 in the Adams Express Company, which contracted with the Pennsylvania to carry its messengers. The money was secured by his mother's placing of a $600 mortgage on the family's $700 home, but the opportunity was available only because of Carnegie's close relationship with Scott. A few years later, he received a few shares in Theodore Tuttle Woodruff's sleeping car company as a reward for holding shares that Woodruff had given to Scott and Thomson, as a payoff. Reinvesting his returns in such inside investments in railroad-related industries (iron, bridges, and rails), Carnegie slowly accumulated capital, the basis for his later success. Throughout his later career, he made use of his close connections to Thomson and Scott, as he established businesses that supplied rails and bridges to the railroad, offering the two men stakes in his enterprises. + +1860–1865: The Civil War + +Before the Civil War, Carnegie arranged a merger between Woodruff's company and that of George Pullman, the inventor of the sleeping car for first-class travel, which facilitated business travel at distances over . The investment proved a success and a source of profit for Woodruff and Carnegie. The young Carnegie continued to work for Pennsylvania's Tom Scott and introduced several improvements in the service. + +In the spring of 1861, Carnegie was appointed by Scott, who was now Assistant Secretary of War in charge of military transportation, as Superintendent of the Military Railways and the Union Government's telegraph lines in the East. Carnegie helped open the rail lines into Washington D.C. that the rebels had cut; he rode the locomotive pulling the first brigade of Union troops to reach Washington D.C. Following the defeat of Union forces at Bull Run, he personally supervised the transportation of the defeated forces. Under his organization, the telegraph service rendered efficient service to the Union cause and significantly assisted in the eventual victory. Carnegie later joked that he was "the first casualty of the war" when he gained a scar on his cheek from freeing a trapped telegraph wire. + +The defeat of the Confederacy required vast supplies of munitions and railroads (and telegraph lines) to deliver the goods. The war demonstrated how integral the industries were to American success. + +Keystone Bridge Company + +In 1864, Carnegie was one of the early investors in the Columbia Oil Company in Venango County, Pennsylvania. In one year, the firm yielded over $1 million in cash dividends, and petroleum from oil wells on the property sold profitably. The demand for iron products, such as armor for gunboats, cannons, and shells, as well as a hundred other industrial products, made Pittsburgh a center of wartime production. Carnegie worked with others in establishing a steel rolling mill, and steel production and control of industry became the source of his fortune. Carnegie had some investments in the iron industry before the war. + +After the war, Carnegie left the railroads to devote his energies to the ironworks trade. Carnegie worked to develop several ironworks, eventually forming the Keystone Bridge Works and the Union Ironworks, in Pittsburgh. Although he had left the Pennsylvania Railroad Company, he remained connected to its management, namely Thomas A. Scott and J. Edgar Thomson. He used his connection to the two men to acquire contracts for his Keystone Bridge Company and the rails produced by his ironworks. He also gave stock in his businesses to Scott and Thomson, and the Pennsylvania was his best customer. When he built his first steel plant, he made a point of naming it after Thomson. As well as having good business sense, Carnegie possessed charm and literary knowledge. He was invited to many important social functions, which Carnegie exploited to his advantage. + +Carnegie, through Keystone, supplied the steel for and owned shares in the landmark Eads Bridge project across the Mississippi River at St. Louis, Missouri (completed 1874). This project was an important proof-of-concept for steel technology, which marked the opening of a new steel market. + +Carnegie believed in using his fortune for others and doing more than making money. He wrote: + +Industrialist + +1875–1900: Steel empire + +Carnegie made his fortune in the steel industry, controlling the most extensive integrated iron and steel operations ever owned by an individual in the United States. One of his two great innovations was in the cheap and efficient mass production of steel by adopting and adapting the Bessemer process, which allowed the high carbon content of pig iron to be burnt away in a controlled and rapid way during steel production. Steel prices dropped as a result, and Bessemer steel was rapidly adopted for rails; however, it was not suitable for buildings and bridges. + +The second was in his vertical integration of all suppliers of raw materials. In 1883, Carnegie bought the rival Homestead Steel Works, which included an extensive plant served by tributary coal and iron fields, a railway, and a line of lake steamships. In the late 1880s, Carnegie Steel was the largest manufacturer of pig iron, steel rails, and coke in the world, with a capacity to produce approximately 2,000 tons of pig iron per day. + +By 1889, the U.S. output of steel exceeded that of the UK, and Carnegie owned a large part of it. Carnegie's empire grew to include the J. Edgar Thomson Steel Works in Braddock (named for John Edgar Thomson, Carnegie's former boss and president of the Pennsylvania Railroad), the Pittsburgh Bessemer Steel Works, the Lucy Furnaces, the Union Iron Mills, the Union Mill (Wilson, Walker & County), the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines. Carnegie combined his assets and those of his associates in 1892 with the launching of the Carnegie Steel Company. + +Carnegie's success was also due to his relationship with the railroad industries, which not only relied on steel for track, but were also making money from steel transport. The steel and railroad barons worked closely to negotiate prices instead of allowing free-market competition. + +Besides Carnegie's market manipulation, United States trade tariffs were also working in favor of the steel industry. Carnegie spent energy and resources lobbying Congress for a continuation of favorable tariffs from which he earned millions of dollars a year. Carnegie tried to keep this information concealed, but legal documents released in 1900, during proceedings with the ex-chairman of Carnegie Steel, Henry Clay Frick, revealed how favorable the tariffs had been. + +1901: U.S. Steel +In 1901, Carnegie was 65 years of age and considering retirement. He reformed his enterprises into conventional joint stock corporations as preparation for this. John Pierpont Morgan was a banker and America's most important financial deal maker. He had observed how efficiently Carnegie produced profits. He envisioned an integrated steel industry that would cut costs, lower prices to consumers, produce in greater quantities and raise wages to workers. To this end, he needed to buy out Carnegie and several other major producers and integrate them into one company, thereby eliminating duplication and waste. He concluded negotiations on March 2, 1901, and formed the United States Steel Corporation. It was the first corporation in the world with a market capitalization of over $1 billion. + +The buyout, secretly negotiated by Charles M. Schwab (no relation to Charles R. Schwab), was the largest such industrial takeover in United States history to date. The holdings were incorporated in the United States Steel Corporation, a trust organized by Morgan, and Carnegie retired from business. His steel enterprises were bought out for $303,450,000. + +Carnegie's share of this amounted to $225.64 million (in , $), which was paid to him in the form of 5%, 50-year gold bonds. The letter agreeing to sell his share was signed on February 26, 1901. On March 2, the circular formally filed the organization and capitalization (at $1.4 billion—4% of the U.S. gross domestic product at the time) of the United States Steel Corporation actually completed the contract. The bonds were to be delivered within two weeks to the Hudson Trust Company of Hoboken, New Jersey, in trust to Robert A. Franks, Carnegie's business secretary. There, a special vault was built to house the physical bulk of nearly $230 million worth of bonds. + +Scholar and activist + +1880–1900 +Carnegie continued his business career; some of his literary intentions were fulfilled. He befriended the English poet Matthew Arnold, the English philosopher Herbert Spencer, and the American humorist Mark Twain, as well as being in correspondence and acquaintance with most of the U.S. Presidents, statesmen, and notable writers. + +Carnegie constructed commodious swimming-baths for the people of his hometown in Dunfermline in 1879. In the following year, Carnegie gave £8,000 for the establishment of a Dunfermline Carnegie Library in Scotland. In 1884, he gave $50,000 to Bellevue Hospital Medical College (now part of New York University Medical Center) to found a histological laboratory, now called the Carnegie Laboratory. + +In 1881, Carnegie took his family, including his 70-year-old mother, on a trip to the United Kingdom. They toured Scotland by coach, and enjoyed several receptions en route. The highlight was a return to Dunfermline, where Carnegie's mother laid the foundation stone of a Carnegie Library which he funded. Carnegie's criticism of British society did not mean dislike; on the contrary, one of Carnegie's ambitions was to act as a catalyst for a close association between English-speaking peoples. To this end, in the early 1880s in partnership with Samuel Storey, he purchased numerous newspapers in Britain, all of which were to advocate the abolition of the monarchy and the establishment of "the British Republic". Carnegie's charm, aided by his wealth, afforded him many British friends, including Prime Minister William Ewart Gladstone. + +In 1886, Carnegie's younger brother Thomas died at age 43. While owning steel works, Carnegie had purchased at low cost the most valuable of the iron ore fields around Lake Superior. + +Following his tour of the UK, he wrote about his experiences in a book entitled An American Four-in-hand in Britain. In 1886, Carnegie wrote his most radical work to date, entitled Triumphant Democracy. Liberal in its use of statistics to make its arguments, the book argued his view that the American republican system of government was superior to the British monarchical system. It gave a highly favorable and idealized view of American progress and criticized the British royal family. The cover depicted an upended royal crown and a broken scepter. The book created considerable controversy in the UK. The book made many Americans appreciate their country's economic progress and sold over 40,000 copies, mostly in the U.S. + +Although actively involved in running his many businesses, Carnegie had become a regular contributor to numerous magazines, most notably The Nineteenth Century, under the editorship of James Knowles, and the influential North American Review, led by the editor Lloyd Bryce. In 1889, Carnegie published "Wealth" in the June issue of the North American Review. After reading it, Gladstone requested its publication in Britain, where it appeared as "The Gospel of Wealth" in The Pall Mall Gazette. Carnegie argued that the life of a wealthy industrialist should comprise two parts. The first part was the gathering and the accumulation of wealth. The second part was for the subsequent distribution of this wealth to benevolent causes. Philanthropy was key to making life worthwhile. + +Carnegie was a well-regarded writer. He published three books on travel. + +Anti-imperialism +In the aftermath of the Spanish–American War, the United States seemed poised to annex Cuba, Guam, Puerto Rico and the Philippines. Carnegie strongly opposed the idea of American colonies. He opposed the annexation of the Philippines almost to the point of supporting William Jennings Bryan against McKinley in 1900. In 1898, Carnegie tried to arrange independence for the Philippines. As the conclusion of the Spanish–American War neared, the United States purchased the Philippines from Spain for $20 million. To counter what he perceived as American imperialism, Carnegie personally offered $20 million to the Philippines so that the Filipino people could purchase their independence from the United States. However, nothing came of the offer. In 1898 Carnegie joined the American Anti-Imperialist League, in opposition to the U.S. annexation of the Philippines. Its membership included former presidents of the United States Grover Cleveland and Benjamin Harrison and literary figures such as Mark Twain. + +1901–1919: Philanthropist + +Carnegie spent his last years as a philanthropist. From 1901 forward, public attention was turned from the shrewd business acumen which had enabled Carnegie to accumulate such a fortune, to the public-spirited way in which he devoted himself to utilizing it on philanthropic projects. He had written about his views on social subjects and the responsibilities of great wealth in Triumphant Democracy (1886) and Gospel of Wealth (1889). Carnegie devoted the rest of his life to providing capital for purposes of public interest and social and educational advancement. He saved letters of appreciation from those he helped in a desk drawer labeled "Gratitude and Sweet Words." + +He provided $25,000 a year to the movement for spelling reform. His organization, the Simplified Spelling Board, created the Handbook of Simplified Spelling, which was written wholly in reformed spelling. + +3,000 public libraries + +Among his many philanthropic efforts, the establishment of public libraries throughout the United States, Britain, Canada and other English-speaking countries was especially prominent. In this special driving interest of his, Carnegie was inspired by meetings with philanthropist Enoch Pratt (1808–1896). The Enoch Pratt Free Library (1886) of Baltimore, Maryland, impressed Carnegie deeply; he said, "Pratt was my guide and inspiration." + +Carnegie turned over management of the library project by 1908 to his staff, led by James Bertram (1874–1934). The first Carnegie Library opened in 1883 in Dunfermline. His method was to provide funds to build and equip the library, but only on the condition that the local authority matched that by providing the land and a budget for operation and maintenance. + +To secure local interest, in 1885, he gave $500,000 to Pittsburgh, Pennsylvania, for a public library; in 1886, he gave $250,000 to Allegheny City, Pennsylvania, for a music hall and library; and he gave $250,000 to Edinburgh for a free library. In total, Carnegie funded some 3,000 libraries, located in 47 U.S. states, and also in Canada, Britain, Ireland, Australia, New Zealand, South Africa, the West Indies, and Fiji. He also donated £50,000 to help set up the University of Birmingham in 1899. + +As Van Slyck (1991) showed, during the last years of the 19th century, there was the increasing adoption of the idea that free libraries should be available to the American public. But the design of such libraries was the subject of prolonged and heated debate. On one hand, the library profession called for designs that supported efficiency in administration and operation; on the other, wealthy philanthropists favored buildings that reinforced the paternalistic metaphor and enhanced civic pride. Between 1886 and 1917, Carnegie reformed both library philanthropy and library design, encouraging a closer correspondence between the two. + +Investing in education, science, pensions, civil heroism, music, and world peace + +In 1900, Carnegie gave $2 million to start the Carnegie Institute of Technology (CIT) at Pittsburgh and the same amount in 1902 to found the Carnegie Institution at Washington, D.C., for encourage research and discovery. He later contributed more to these and other schools. CIT is now known as Carnegie Mellon University after it merged with the Mellon Institute of Industrial Research. Carnegie also served on the Boards of Cornell University and Stevens Institute of Technology. + +In 1911, Carnegie became a sympathetic benefactor to George Ellery Hale, who was trying to build the Hooker Telescope at Mount Wilson, and donated an additional ten million dollars to the Carnegie Institution with the following suggestion to expedite the construction of the telescope: "I hope the work at Mount Wilson will be vigorously pushed, because I am so anxious to hear the expected results from it. I should like to be satisfied before I depart, that we are going to repay to the old land some part of the debt we owe them by revealing more clearly than ever to them the new heavens." The telescope saw first light on November 2, 1917, with Carnegie still alive. + +In 1901, in Scotland, he gave $10 million to establish the Carnegie Trust for the Universities of Scotland. It was created by a deed that he signed on June 7, 1901, and it was incorporated by royal charter on August 21, 1902. The establishing gift of $10 million was then an unprecedented sum: at the time, total government assistance to all four Scottish universities was about £50,000 a year. The aim of the Trust was to improve and extend the opportunities for scientific research in the Scottish universities and to enable the deserving and qualified youth of Scotland to attend a university. He was subsequently elected Lord Rector of University of St. Andrews in December 1901, and formally installed as such in October 1902, serving until 1907. He also donated large sums of money to Dunfermline, the place of his birth. In addition to a library, Carnegie also bought the private estate which became Pittencrieff Park and opened it to all members of the public, establishing the Carnegie Dunfermline Trust to benefit the people of Dunfermline. A statue of Carnegie was later built between 1913 and 1914 in the park as a commemoration for his creation of the park. + +Carnegie was a major patron of music. He was a founding financial backer of Jeannette Thurber's National Conservatory of Music of America in 1885. He built the music performing venue Carnegie Hall in New York City; it opened in 1891 and remained in his family until 1925. His interest in music led him to fund the construction of 7,000 pipe organs in churches and temples, with no apparent preference for any religious denomination or sect. + +He gave a further $10 million in 1913 to endow the Carnegie United Kingdom Trust, a grant-making foundation. He transferred to the trust the charge of all his existing and future benefactions, other than university benefactions in the United Kingdom. He gave the trustees a wide discretion, and they inaugurated a policy of financing rural library schemes rather than erecting library buildings, and of assisting the musical education of the people rather than granting organs to churches. + +In 1901, Carnegie also established large pension funds for his former employees at Homestead and, in 1905, for American college professors. The latter fund evolved into TIAA-CREF. One critical requirement was that church-related schools had to sever their religious connections to get his money. + +Carnegie was a large benefactor of the Tuskegee Institute for African-American education under Booker T. Washington. He helped Washington create the National Negro Business League. + +In 1904, he founded the Carnegie Hero Fund for the United States and Canada (a few years later also established in the United Kingdom, Switzerland, Norway, Sweden, France, Italy, the Netherlands, Belgium, Denmark, and Germany) for the recognition of deeds of heroism. Carnegie contributed $1.5 million in 1903 for the erection of the Peace Palace at The Hague; and he donated $150,000 for a Pan-American Palace in Washington as a home for the International Bureau of American Republics. + +When it became obvious that Carnegie could not give away his entire fortune within his lifetime, he established the Carnegie Corporation of New York in 1911 "to promote the advancement and diffusion of knowledge and understanding" and continue his program of giving. + +Carnegie was honored for his philanthropy and support of the arts by initiation as an honorary member of Phi Mu Alpha Sinfonia fraternity on October 14, 1917, at the New England Conservatory of Music in Boston, Massachusetts. The fraternity's mission reflects Carnegie's values by developing young men to share their talents to create harmony in the world. + +By the standards of 19th-century tycoons, Carnegie was not a particularly ruthless man but a humanitarian with enough acquisitiveness to go in the ruthless pursuit of money. "Maybe with the giving away of his money," commented biographer Joseph Wall, "he would justify what he had done to get that money." + +To some, Carnegie represents the idea of the American dream. He was an immigrant from Scotland who came to America and became successful. He is not only known for his successes but his huge amounts of philanthropic works, not only for charities but also to promote democracy and independence to colonized countries. + +Death + +Carnegie died on August 11, 1919, in Lenox, Massachusetts, at his Shadow Brook estate, of Bronchial Pneumonia. He had already given away $350,695,653 (approximately US$ in dollars) of his wealth. After his death, his last $30 million was given to foundations, charities, and to pensioners. He was buried at Sleepy Hollow Cemetery in Sleepy Hollow, New York. The grave site is located on the Arcadia Hebron plot of land at the corner of Summit Avenue and Dingle Road. Carnegie is buried only a few yards away from union organizer Samuel Gompers, another important figure of industry in the Gilded Age. + +Controversies + +1889: Johnstown Flood + +Carnegie was one of more than 50 members of the South Fork Fishing and Hunting Club, which has been blamed for the Johnstown Flood that killed 2,209 people in 1889. + +At the suggestion of his friend Benjamin Ruff, Carnegie's partner Henry Clay Frick had formed the exclusive South Fork Fishing and Hunting Club high above Johnstown, Pennsylvania. The sixty-odd club members were the leading business tycoons of Western Pennsylvania and included among their number Frick's best friend, Andrew Mellon, his attorneys Philander Knox and James Hay Reed, as well as Frick's business partner, Carnegie. High above the city, near the small town of South Fork, the South Fork Dam was originally built between 1838 and 1853 by the Commonwealth of Pennsylvania as part of a canal system to be used as a reservoir for a canal basin in Johnstown. With the coming-of-age of railroads superseding canal barge transport, the lake was abandoned by the Commonwealth, sold to the Pennsylvania Railroad, and sold again to private interests, and eventually came to be owned by the South Fork Fishing and Hunting Club in 1881. Prior to the flood, speculators had purchased the abandoned reservoir, made less than well-engineered repairs to the old dam, raised the lake level, built cottages and a clubhouse, and created the South Fork Fishing and Hunting Club. Less than downstream from the dam sat the city of Johnstown. + +The dam was high and long. Between 1881, when the club was opened, and 1889, the dam frequently sprang leaks and was patched, mostly with mud and straw. Additionally, a previous owner removed and sold for scrap the three cast iron discharge pipes that previously allowed a controlled release of water. There had been some speculation as to the dam's integrity, and concerns had been raised by the head of the Cambria Iron Works downstream in Johnstown. Such repair work, a reduction in height, and unusually high snowmelt and heavy spring rains combined to cause the dam to give way on May 31, 1889, resulting in twenty million tons of water sweeping down the valley as the Johnstown Flood. When word of the dam's failure was telegraphed to Pittsburgh, Frick and other members of the South Fork Fishing and Hunting Club gathered to form the Pittsburgh Relief Committee for assistance to the flood victims as well as determining never to speak publicly about the club or the flood. This strategy was a success, and Knox and Reed were able to fend off all lawsuits that would have placed blame upon the club's members. + +Although Cambria Iron and Steel's facilities were heavily damaged by the flood, they returned to full production within a year. After the flood, Carnegie built Johnstown a new library to replace the one built by Cambria's chief legal counsel Cyrus Elder, which was destroyed in the flood. The Carnegie-donated library is now owned by the Johnstown Area Heritage Association, and houses the Flood Museum. + +1892: Homestead Strike + +The Homestead Strike was a bloody labor confrontation lasting 143 days in 1892, one of the most serious in U.S. history. The conflict was centered on Carnegie Steel's main plant in Homestead, Pennsylvania, and grew out of a labor dispute between the Amalgamated Association of Iron and Steel Workers (AA) and the Carnegie Steel Company. + +Carnegie left on a trip to Scotland before the unrest peaked. In doing so, Carnegie left mediation of the dispute in the hands of his associate and partner Henry Clay Frick. Frick was well known in industrial circles for maintaining staunch anti-union sentiment. With the collective bargaining agreement between the union and company expiring at the end of June, Frick and the leaders of the local AA union entered into negotiations in February. With the steel industry doing well and prices higher, the AA asked for a wage increase; the AA represented about 800 of the 3,800 workers at the plant. Frick immediately countered with an average 22% wage decrease that would affect nearly half the union's membership and remove a number of positions from the bargaining unit. + +The union and company failed to come to an agreement, and management locked the union out. Workers considered the stoppage a "lockout" by management and not a "strike" by workers. As such, the workers would have been well within their rights to protest, and subsequent government action would have been a set of criminal procedures designed to crush what was seen as a pivotal demonstration of the growing labor rights movement, strongly opposed by management. Frick brought in thousands of strikebreakers to work the steel mills and Pinkerton agents to safeguard them. + +On July 6, the arrival of a force of 300 Pinkerton agents from New York City and Chicago resulted in a fight in which 10 men — seven strikers and three Pinkertons — were killed and hundreds were injured. Pennsylvania Governor Robert Pattison ordered two brigades of the state militia to the strike site. Then allegedly in response to the fight between the striking workers and the Pinkertons, anarchist Alexander Berkman shot at Frick in an attempted assassination, wounding him. While not directly connected to the strike, Berkman was tied in for the assassination attempt. According to Berkman, "...with the elimination of Frick, responsibility for Homestead conditions would rest with Carnegie." Afterwards, the company successfully resumed operations with non-union immigrant employees in place of the Homestead plant workers, and Carnegie returned to the United States. However, Carnegie's reputation was permanently damaged by the Homestead events. + +Theodore Roosevelt +According to David Nasaw, after 1898, when the United States entered a war with Spain, Carnegie increasingly devoted his energy to supporting pacifism. He strongly opposed the war and the subsequent imperialistic American takeover of the Philippines. When Theodore Roosevelt became president in 1901, Carnegie and Roosevelt were in frequent contact. They exchanged letters, communicated through mutual friends such as Secretary of State John Hay, and met in person. Carnegie hoped that Roosevelt would turn the Philippines free, not realizing he was more of an imperialist and believer in warrior virtues than President McKinley had been. He saluted Roosevelt for forcing Germany and Britain to arbitrate their conflict with Venezuela in 1903, and especially for becoming the mediator who negotiated an end to the war between Russia and Japan in 1907–1908. Roosevelt relied on Carnegie for financing his expedition to Africa in 1909. In return he asked the ex-president to mediate the growing conflict between the cousins who ruled Britain and Germany. Roosevelt started to do so but the scheme collapsed when king Edward VII suddenly died. Nasaw argues that Roosevelt systematically deceived and manipulated Carnegie, and held the elderly man in contempt. Nasaw quotes a private letter Roosevelt wrote to Whitelaw Reid in 1905: [I have] tried hard to like Carnegie, but it is pretty difficult. There is no type of man for whom I feel a more contemptuous abhorrence than for the one who makes a God of mere money-making and at the same time is always yelling out that kind of utterly stupid condemnation of war which in almost every case springs from a combination of defective physical courage, of unmanly shrinking from pain and effort, and of hopelessly twisted ideals. All the suffering from Spanish war comes far short of the suffering, preventable and non-preventable, among the operators of the Carnegie steel works, and among the small investors, during the time that Carnegie was making his fortune…. It is as noxious folly to denounce war per se as it is to denounce business per se. Unrighteous war is a hideous evil; but I am not at all sure that it is worse evil than business unrighteousness. + +Personal life + +Family + +Carnegie did not want to marry during his mother's lifetime, instead choosing to take care of her in her illness towards the end of her life. After she died in 1886, the 51-year-old Carnegie married Louise Whitfield, who was 21 years his junior. In 1897, the couple had their only child, Margaret, who they named after Carnegie's mother. + +Residence + +Carnegie bought Skibo Castle in Scotland, and made his home partly there and partly in his New York mansion located at 2 East 91st Street at Fifth Avenue. The building was completed in late 1902, and he lived there until his death in 1919. His wife Louise continued to live there until her death in 1946. The building is now used as the Cooper-Hewitt, Smithsonian Design Museum, part of the Smithsonian Institution. The surrounding neighborhood on Manhattan's Upper East Side has come to be called Carnegie Hill. The mansion was designated as a National Historic Landmark in 1966. + +Philosophy + +Politics +Carnegie gave "formal allegiance" to the Republican Party, though he was said to be "a violent opponent of some of the most sacred doctrines" of the party. + +Andrew Carnegie Dictum +In his final days, Carnegie had pneumonia. Before his death on August 11, 1919, Carnegie had donated $350,695,654 for various causes. The "Andrew Carnegie Dictum" was: +To spend the first third of one's life getting all the education one can. +To spend the next third making all the money one can. +To spend the last third giving it all away for worthwhile causes. +Carnegie was involved in philanthropic causes, but he kept himself away from religious circles. He wanted to be identified by the world as a "positivist". He was highly influenced in public life by John Bright. + +On wealth + +As early as 1868, at age 33, he drafted a memo to himself. He wrote: "...The amassing of wealth is one of the worse species of idolatry. No idol more debasing than the worship of money." In order to avoid degrading himself, he wrote in the same memo he would retire at age 35 to pursue the practice of philanthropic giving, for "... the man who dies thus rich dies disgraced." However, he did not begin his philanthropic work in all earnest until 1881, at age 46, with the gift of a library to his hometown of Dunfermline, Scotland. + +Carnegie wrote "The Gospel of Wealth", an article in which he stated his belief that the rich should use their wealth to help enrich society. In that article, Carnegie also expressed sympathy for the ideas of progressive taxation and an estate tax: + +The following is taken from one of Carnegie's memos to himself: + +Intellectual influences + +Carnegie claimed to be a champion of evolutionary thought—particularly the work of Herbert Spencer, even declaring Spencer his teacher. Although Carnegie claimed to be a disciple of Spencer, many of his actions went against the ideas he espoused. + +Spencerian evolution was for individual rights and against government interference. Furthermore, Spencerian evolution held that those unfit to sustain themselves must be allowed to perish. Spencer believed that just as there were many varieties of beetles, respectively modified to existence in a particular place in nature, so too had human society "spontaneously fallen into division of labour". Individuals who survived to this, the latest and highest stage of evolutionary progress would be "those in whom the power of self-preservation is the greatest—are the select of their generation." Moreover, Spencer perceived governmental authority as borrowed from the people to perform the transitory aims of establishing social cohesion, insurance of rights, and security. Spencerian 'survival of the fittest' firmly credits any provisions made to assist the weak, unskilled, poor and distressed to be an imprudent disservice to evolution. Spencer insisted people should resist for the benefit of collective humanity, as severe fate singles out the weak, debauched, and disabled. + +Andrew Carnegie's political and economic focus during the late nineteenth and early twentieth century was the defense of laissez-faire economics. Carnegie emphatically resisted government intrusion in commerce, as well as government-sponsored charities. Carnegie believed the concentration of capital was essential for societal progress and should be encouraged. Carnegie was an ardent supporter of commercial "survival of the fittest" and sought to attain immunity from business challenges by dominating all phases of the steel manufacturing procedure. Carnegie's determination to lower costs included cutting labor expenses as well. In a notably Spencerian manner, Carnegie argued that unions impeded the natural reduction of prices by pushing up costs, which blocked evolutionary progress. Carnegie felt that unions represented the narrow interest of the few while his actions benefited the entire community. + +On the surface, Andrew Carnegie appears to be a strict laissez-faire capitalist and follower of Herbert Spencer, often referring to himself as a disciple of Spencer. Conversely, Carnegie, a titan of industry, seems to embody all of the qualities of Spencerian survival of the fittest. The two men enjoyed a mutual respect for one another and maintained a correspondence until Spencer's death in 1903. There are, however, some major discrepancies between Spencer's capitalist evolutionary conceptions and Andrew Carnegie's capitalist practices. + +Spencer wrote that in production the advantages of the superior individual are comparatively minor, and thus acceptable, yet the benefit that dominance provides those who control a large segment of production might be hazardous to competition. Spencer feared that an absence of "sympathetic self-restraint" of those with too much power could lead to the ruin of their competitors. He did not think free-market competition necessitated competitive warfare. Furthermore, Spencer argued that individuals with superior resources who deliberately used investment schemes to put competitors out of business were committing acts of "commercial murder". Carnegie built his wealth in the steel industry by maintaining an extensively integrated operating system. Carnegie also bought out some regional competitors, and merged with others, usually maintaining the majority shares in the companies. Over the course of twenty years, Carnegie's steel properties grew to include the Edgar Thomson Steel Works, the Lucy Furnace Works, the Union Iron Mills, the Homestead Works, the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines among many other industry-related assets. + +Herbert Spencer absolutely was against government interference in business in the form of regulatory limitations, taxes, and tariffs as well. Spencer saw tariffs as a form of taxation that levied against the majority in service to "the benefit of a small minority of manufacturers and artisans". + +Despite Carnegie's personal dedication to Herbert Spencer as a friend, his adherence to Spencer's political and economic ideas is more contentious. In particular, it appears Carnegie either misunderstood or intentionally misrepresented some of Spencer's principal arguments. Spencer remarked upon his first visit to Carnegie's steel mills in Pittsburgh, which Carnegie saw as the manifestation of Spencer's philosophy, "Six months' residence here would justify suicide." + +On the subject of charity Andrew Carnegie's actions diverged in the most significant and complex manner from Herbert Spencer's philosophies. In his 1854 essay "Manners and Fashion", Spencer referred to public education as "Old schemes". He went on to declare that public schools and colleges fill the heads of students with inept, useless knowledge and exclude useful knowledge. Spencer stated that he trusted no organization of any kind, "political, religious, literary, philanthropic", and believed that as they expanded in influence so too did their regulations expand. In addition, Spencer thought that as all institutions grow they become evermore corrupted by the influence of power and money. The institution eventually loses its "original spirit, and sinks into a lifeless mechanism". Spencer insisted that all forms of philanthropy that uplift the poor and downtrodden were reckless and incompetent. Spencer thought any attempt to prevent "the really salutary sufferings" of the less fortunate "bequeath to posterity a continually increasing curse". Carnegie, a self-proclaimed devotee of Spencer, testified to Congress on February 5, 1915: "My business is to do as much good in the world as I can; I have retired from all other business." + +Carnegie held that societal progress relied on individuals who maintained moral obligations to themselves and to society. Furthermore, he believed that charity supplied the means for those who wish to improve themselves to achieve their goals. Carnegie urged other wealthy people to contribute to society in the form of parks, works of art, libraries and other endeavors that improve the community and contribute to the "lasting good". Carnegie also held a strong opinion against inherited wealth. Carnegie believed that the sons of prosperous businesspersons were rarely as talented as their fathers. By leaving large sums of money to their children, wealthy business leaders were wasting resources that could be used to benefit society. Most notably, Carnegie believed that the future leaders of society would rise from the ranks of the poor. Carnegie strongly believed in this because he had risen from the bottom. He believed the poor possessed an advantage over the wealthy because they receive greater attention from their parents and are taught better work ethics. + +Religion and worldview +Carnegie and his family belonged to the Presbyterian Church in the United States of America, also known informally as the Northern Presbyterian Church. In his early life Carnegie was skeptical of Calvinism, and religion as a whole, but reconciled with it later in his life. In his autobiography, Carnegie describes his family as moderate Presbyterian believers, writing that "there was not one orthodox Presbyterian" in his family; various members of his family having somewhat distanced themselves from Calvinism, some of them leaning more towards Swedenborgianism. While a child, his family led vigorous theological and political disputes. His mother avoided the topic of religion. His father left the Presbyterian church after a sermon on infant damnation, while, according to Carnegie, still remaining very religious on his own. + +Witnessing sectarianism and strife in 19th century Scotland regarding religion and philosophy, Carnegie kept his distance from organized religion and theism. Carnegie instead preferred to see things through naturalistic and scientific terms stating, "Not only had I got rid of the theology and the supernatural, but I had found the truth of evolution." + +Later in life, Carnegie's firm opposition to religion softened. For many years he was a member of Madison Avenue Presbyterian Church, pastored from 1905 to 1926 by Social Gospel exponent Henry Sloane Coffin, while his wife and daughter belonged to the Brick Presbyterian Church. He also prepared (but did not deliver) an address in which he professed a belief in "an Infinite and Eternal Energy from which all things proceed". Records exist of a short period of correspondence around 1912–1913 between Carnegie and 'Abdu'l-Bahá, the eldest son of Bahá'u'lláh, founder of the Baháʼí Faith. In these letters, one of which was published in The New York Times in full text, Carnegie is extolled as a "lover of the world of humanity and one of the founders of Universal Peace". + +World peace + +Influenced by his "favorite living hero in public life" John Bright, Carnegie started his efforts in pursuit of world peace at a young age, and supported causes that opposed military intervention. His motto, "All is well since all grows better", served not only as a good rationalization of his successful business career, but also his view of international relations. + +Despite his efforts towards international peace, Carnegie faced many dilemmas on his quest. These dilemmas are often regarded as conflicts between his view on international relations and his other loyalties. Throughout the 1880s and 1890s, for example, Carnegie allowed his steel works to fill large orders of armor plate for the building of an enlarged and modernized United States Navy, but he opposed American overseas expansion. + +Despite that, Carnegie served as a major donor for the newly established International Court of Arbitration's Peace Palace—brainchild of Russian tsar Nicholas II. + +His largest and in the long run most influential peace organization was the Carnegie Endowment for International Peace, formed in 1910 with a $10 million endowment. In 1913, at the dedication of the Peace Palace in The Hague, Carnegie predicted that the end of the war was as certain to come, and come soon, as day follows night. + +In 1914, on the eve of the First World War, Carnegie founded the Church Peace Union (CPU), a group of leaders in religion, academia, and politics. Through the CPU, Carnegie hoped to mobilize the world's churches, religious organizations, and other spiritual and moral resources to join in promoting moral leadership to put an end to war forever. For its inaugural international event, the CPU sponsored a conference to be held on August 1, 1914, on the shores of Lake Constance in southern Germany. As the delegates made their way to the conference by train, Germany was invading Belgium. + +Despite its inauspicious beginning, the CPU thrived. Today its focus is on ethics and it is known as the Carnegie Council for Ethics in International Affairs, an independent, nonpartisan, nonprofit organization, whose mission is to be the voice for ethics in international affairs. + +The outbreak of the First World War was clearly a shock to Carnegie and his optimistic view on world peace. Although his promotion of anti-imperialism and world peace had all failed, and the Carnegie Endowment had not fulfilled his expectations, his beliefs and ideas on international relations had helped build the foundation of the League of Nations after his death, which took world peace to another level. + +United States colonial expansion +On the matter of American colonial expansion, Carnegie had always thought it is an unwise gesture for the United States. He did not oppose the annexation of the Hawaiian islands or Puerto Rico, but he opposed the annexation of the Philippines. Carnegie believed that it involved a denial of the fundamental democratic principle, and he also urged William McKinley to withdraw American troops and allow the Filipinos to live with their independence. This act strongly impressed the other American anti-imperialists, who soon elected him vice-president of the Anti-Imperialist League. + +After he sold his steel company in 1901, Carnegie was able to get fully involved in the peace cause, both financially and personally. He gave away much of his fortunes to various peacekeeping agencies in order to keep them growing. When a friend, the British writer William T. Stead, asked him to create a new organization for the goal of a peace and arbitration society, his reply was: + +Carnegie believed that it is the effort and will of the people, that maintains the peace in international relations. Money is just a push for the act. If world peace depended solely on financial support, it would not seem a goal, but more like an act of pity. + +Like Stead, he believed that the United States and the British Empire would merge into one nation, telling him "We are heading straight to the Re-United States". Carnegie believed that the combined country's power would maintain world peace and disarmament. The creation of the Carnegie Endowment for International Peace in 1910 was regarded as a milestone on the road to the ultimate goal of abolition of war. Beyond a gift of $10 million for peace promotion, Carnegie also encouraged the "scientific" investigation of the various causes of war, and the adoption of judicial methods that should eventually eliminate them. He believed that the Endowment exists to promote information on the nations' rights and responsibilities under existing international law and to encourage other conferences to codify this law. + +Legacy and honors + +Carnegie received the honorary Doctor of Laws (DLL) from the University of Glasgow in June 1901, and received the Freedom of the City of Glasgow "in recognition of his munificence" later the same year. In July 1902 he received the Freedom of the city of St Andrews, "in testimony of his great zeal for the welfare of his fellow-men on both sides of the Atlantic", and in October 1902 the Freedom of the City of Perth "in testimony of his high personal worth and beneficial influence, and in recognition of widespread benefactions bestowed on this and other lands, and especially in gratitude for the endowment granted by him for the promotion of University education in Scotland" and the Freedom of the City of Dundee. Also in 1902, he was elected as a member to the American Philosophical Society. He received an honorary Doctor of Laws (LLD) from the University of Aberdeen in 1906. In 1910, he received the Freedom of the City of Belfast and was made as well Commander of the National Order of the Legion of Honour by the French government. Carnegie was awarded as Knight Grand Cross of the Order of Orange-Nassau by Queen Wilhelmina of the Netherlands on August 25, 1913. Carnegie received July 1, 1914 an honorary doctorate from the University of Groningen the Netherlands. + +The dinosaur Diplodocus carnegiei (Hatcher) was named for Carnegie after he sponsored the expedition that discovered its remains in the Morrison Formation (Jurassic) of Utah. Carnegie was so proud of "Dippy" that he had casts made of the bones and plaster replicas of the whole skeleton donated to several museums in Europe and South America. The original fossil skeleton is assembled and stands in the Hall of Dinosaurs at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. +After the Spanish–American War, Carnegie offered to donate $20 million to the Philippines so they could buy their independence. +Carnegie, Pennsylvania, and Carnegie, Oklahoma, were named in his honor. +The Saguaro cactus's scientific name, Carnegiea gigantea, is named after him. +The Carnegie Medal for the best children's literature published in the UK was established in his name. +The Carnegie Faculty of Sport and Education, at Leeds Beckett University, UK, is named after him. +The concert halls in Dunfermline and New York are named after him. +At the height of his career, Carnegie was the second-richest person in the world, behind only John D. Rockefeller of Standard Oil. +Carnegie Mellon University in Pittsburgh was named after Carnegie, who founded the institution as the Carnegie Technical Schools. +Lauder College (named after his uncle George Lauder Sr.) in the Halbeath area of Dunfermline was renamed Carnegie College in 2007. +A street in Belgrade (Serbia), next to the Belgrade University Library which is one of the Carnegie libraries, is named in his honor. +An American high school, Carnegie Vanguard High School in Houston, Texas, is named after him +Carnegie was awarded the Freedom of the Burgh of Kilmarnock in Scotland in 1903, prior to laying the foundation stone of Loanhead Public School. + +Benefactions + +According to biographer Burton J. Hendrick: +His benefactions amounted to $350,000,000—for he gave away not only his annual income of something more than $12,500,000, but most of the principal as well. Of this sum, $62,000,000 was allotted to the British Empire and $288,000,000 to the United States, for Carnegie, in the main, confined his benefactions to the English-speaking nations. His largest gifts were $125,000,000 to the Carnegie Corporation of New York (this same body also became his residuary legatee), $60,000,000 to public library buildings, $20,000,000 to colleges (usually the smaller ones), $6,000,000 to church organs, $29,000,000 to the Carnegie Foundation for the Advancement of Teaching, $22,000,000 to the Carnegie Institute of Pittsburgh, $22,000,000 to the Carnegie Institution of Washington, $10,000,000 to Hero Funds, $10,000,000 to the Endowment for International Peace, $10,000,000 to the Scottish Universities Trust, $10,000,000 to the United Kingdom Trust, and $3,750,000 to the Dunfermline Trust. + +Hendrick argues that: + +These gifts fairly picture Carnegie's conception of the best ways to improve the status of the common man. They represent all his personal tastes—his love of books, art, music, and nature—and the reforms which he regarded as most essential to human progress—scientific research, education both literary and technical, and, above all, the abolition of war. The expenditure the public most associates with Carnegie's name is that for public libraries. Carnegie himself frequently said that his favorite benefaction was the Hero Fund—among other reasons, because "it came up my ain back"; but probably deep in his own mind his library gifts took precedence over all others in importance. There was only one genuine remedy, he believed, for the ills that beset the human race, and that was enlightenment. "Let there be light" was the motto that, in the early days, he insisted on placing in all his library buildings. As to the greatest endowment of all, the Carnegie Corporation, that was merely Andrew Carnegie in permanently organized form; it was established to carry on, after Carnegie's death, the work to which he had given personal attention in his own lifetime. + +Research sources +Carnegie's personal papers are at the Library of Congress Manuscript Division. +The Carnegie Collections of the Columbia University Rare Book and Manuscript Library consist of the archives of the following organizations founded by Carnegie: The Carnegie Corporation of New York (CCNY); The Carnegie Endowment for International Peace (CEIP); the Carnegie Foundation for the Advancement of Teaching (CFAT);The Carnegie Council on Ethics and International Affairs (CCEIA). These collections deal primarily with Carnegie philanthropy and have very little personal material related to Carnegie.

Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like (as in rest) and semivowels like and (as in yes and west, respectively), as well as lateral approximants like (as in less). + +Terminology + +Before Peter Ladefoged coined the term "approximant" in the 1960s, the terms "frictionless continuant" and "semivowel" were used to refer to non-lateral approximants. + +In phonology, "approximant" is also a distinctive feature that encompasses all sonorants except nasals, including vowels, taps and trills. + +Semivowels + +Some approximants resemble vowels in acoustic and articulatory properties and the terms semivowel and glide are often used for these non-syllabic vowel-like segments. The correlation between semivowels and vowels is strong enough that cross-language differences between semivowels correspond with the differences between their related vowels. + +Vowels and their corresponding semivowels alternate in many languages depending on the phonological environment, or for grammatical reasons, as is the case with Indo-European ablaut. Similarly, languages often avoid configurations where a semivowel precedes its corresponding vowel. A number of phoneticians distinguish between semivowels and approximants by their location in a syllable. Although he uses the terms interchangeably, remarks that, for example, the final glides of English par and buy differ from French par ('through') and baille ('tub') in that, in the latter pair, the approximants appear in the syllable coda, whereas, in the former, they appear in the syllable nucleus. This means that opaque (if not minimal) contrasts can occur in languages like Italian (with the i-like sound of piede 'foot', appearing in the nucleus: , and that of piano 'plan', appearing in the syllable onset: ) and Spanish (with a near minimal pair being abyecto 'abject' and abierto 'opened'). +{|class="wikitable" +|- +|+Approximant-vowel correspondences +!

A transcription with the IPA character for an alveolar approximant () is common, though the sound is more postalveolar. Actual retroflexion may occur as well and both occur as variations of the same sound. However, makes a distinction between the vowels of American English (which he calls "rhotacized") and vowels with "retroflexion" such as those that appear in Badaga; , on the other hand, labels both as r-colored and notes that both have a lowered third formant. + Because the vowels are articulated with spread lips, spreading is implied for their approximant analogues, . However, these sounds generally have little or no lip-spreading. The fricative letters with a lowering diacritic, , may therefore be justified for a neutral articulation between spread and rounded . + +In articulation and often diachronically, palatal approximants correspond to front vowels, velar approximants to back vowels, and labialized approximants to rounded vowels. In American English, the rhotic approximant corresponds to the rhotic vowel. This can create alternations (as shown in the above table). + +In addition to alternations, glides can be inserted to the left or the right of their corresponding vowels when they occur next to a hiatus. For example, in Ukrainian, medial triggers the formation of an inserted that acts as a syllable onset so that when the affix is added to футбол ('football') to make футболіст 'football player', it is pronounced , but маоїст ('Maoist'), with the same affix, is pronounced with a glide. Dutch for many speakers has a similar process that extends to mid vowels: + bioscoop → ('cinema') + zee + en → ('seas') + fluor → ('fluorine') + reu + en → ('male dogs') + Rwanda → ('Rwanda') + Boaz → ('Boaz') + +Similarly, vowels can be inserted next to their corresponding glide in certain phonetic environments. Sievers' law describes this behaviour for Germanic. + +Non-high semivowels also occur. In colloquial Nepali speech, a process of glide-formation occurs, where one of two adjacent vowels becomes non-syllabic; the process includes mid vowels so that ('cause to wish') features a non-syllabic mid vowel. Spanish features a similar process and even nonsyllabic can occur so that ahorita ('right away') is pronounced . It is not often clear, however, whether such sequences involve a semivowel (a consonant) or a diphthong (a vowel), and in many cases, it may not be a meaningful distinction. + +Although many languages have central vowels , which lie between back/velar and front/palatal , there are few cases of a corresponding approximant . One is in the Korean diphthong or though it is more frequently analyzed as velar (as in the table above), and Mapudungun may be another, with three high vowel sounds, , , and three corresponding consonants, , and , and a third one is often described as a non-labialized voiced velar fricative; some texts note a correspondence between this approximant and that is parallel to – and –. An example is liq (?) ('white'). +It has been noted that the expected symbols for the approximant correlates of are or . + +Approximants versus fricatives +In addition to less turbulence, approximants also differ from fricatives in the precision required to produce them. When emphasized, approximants may be slightly fricated (that is, the airstream may become slightly turbulent), which is reminiscent of fricatives. For example, the Spanish word ayuda ('help') features a palatal approximant that is pronounced as a fricative in emphatic speech. Spanish can be analyzed as having a meaningful distinction between fricative, approximant, and intermediate . However, such frication is generally slight and intermittent, unlike the strong turbulence of fricative consonants. + +For places of articulation further back in the mouth, languages do not contrast voiced fricatives and approximants. Therefore, the IPA allows the symbols for the voiced fricatives to double for the approximants, with or without a lowering diacritic. + +Occasionally, the glottal "fricatives" are called approximants, since typically has no more frication than voiceless approximants, but they are often phonations of the glottis without any accompanying manner or place of articulation. + +Central approximants + +bilabial approximant (usually transcribed ) +labiodental approximant +dental approximant (usually transcribed ) +alveolar approximant +retroflex approximant (a consonantal ) +palatal approximant (a consonantal ) +velar approximant (a consonantal ) +uvular approximant (a consonantal , usually transcribed ) +pharyngeal approximant (a consonantal ; usually transcribed ) +breathy-voiced glottal approximant +creaky-voiced glottal approximant + +Lateral approximants +In lateral approximants, the center of tongue makes solid contact with the roof of the mouth.

There are problems in distinguishing voiceless approximants from voiceless fricatives. + +Phonetic characteristics +Fricative consonants are generally said to be the result of turbulent airflow at a place of articulation in the vocal tract. However, an audible voiceless sound may be made without this turbulent airflow: makes a distinction between "local friction" (as in or ) and "cavity friction" (as in voiceless vowels like and ). More recent research distinguishes between "turbulent" and "laminar" airflow in the vocal tract. It is not clear if it is possible to describe voiceless approximants categorically as having laminar airflow (or cavity friction in Pike's terms) as a way of distinguishing them from fricatives. write that "the airflow for voiced approximants remains laminar (smooth), and does not become turbulent. Voiceless approximants are rare in the languages of the world, but when they do occur the airflow is usually somewhat turbulent." Audible voiceless sounds may also be produced by means of turbulent airflow at the glottis, as in ; in such a case, it is possible to articulate an audible voiceless sound without the production of local friction at a supraglottal constriction. describes such sounds, but classes them as sonorants. + +Distinctiveness +Voiceless approximants are rarely if ever distinguished phonemically from voiceless fricatives in the sound system of a language. discuss the issue and conclude "In practice, it is difficult to distinguish between a voiceless approximant and a voiceless fricative at the same place of articulation ... there is no evidence that any language in the world makes such a distinction crucial." + +Disagreement over use of the term +Voiceless approximants are treated as a phonetic category by (among others) , , and . However, the term voiceless approximant is seen by some phoneticians as controversial. It has been pointed out that if approximant is defined as a speech sound that involves the articulators approaching each other but not narrowly enough to create turbulent airflow, then it is difficult to see how a voiceless approximant could be audible. As John C. Wells puts it in his blog, "voiceless approximants are by definition inaudible ... If there's no friction and no voicing, there's nothing to hear." A similar point is made in relation to frictionless continuants by : "There are no voiceless frictionless continuants because this would imply silence; the voiceless counterpart of the frictionless continuant is the voiceless fricative." argue that the increased airflow arising from voicelessness alone makes a voiceless continuant a fricative, even if lacking a greater constriction in the oral cavity than a voiced approximant. + + argue that Burmese and Standard Tibetan have voiceless lateral approximants and Navajo and Zulu voiceless lateral fricatives , but also say that "in other cases it is difficult to decide whether a voiceless lateral should be described as an approximant or a fricative". compared voiceless laterals in Estonian Swedish, Icelandic, and Welsh and found that Welsh-speakers consistently used , that Icelandic-speakers consistently used , and that speakers of Estonian Swedish varied in their pronunciation. They conclude that there is "a range of variants within voiceless laterals, rather than a categorical split between lateral fricatives and voiceless approximant laterals". + +Occurrence in Western American English +Voiceless lateral approximants can occur after voiceless stops as allophone of its voiced counterpart, especially after the voiceless velar plosive , in Western American English. + +Nasalized approximants +Examples are: +nasal palatal approximant +nasal labialized velar approximant +voiceless nasal glottal approximant + +In Portuguese, the nasal glides and historically became and in some words.

It is a Latin transliteration from the ancient Greek word (), from the archaic () meaning "century". In Greek, it literally refers to the timespan of one hundred years.

That is, after the period of the aeons, all punishment will cease and death is overcome and then God becomes the all in each one ().

Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. + +The first airline was the German airship company DELAG, founded on November 16, 1909.

On July 15 , 1919, the company flew a proving flight across the English Channel, despite a lack of support from the British government. Flown by Lt. H Shaw in an Airco DH.9 between RAF Hendon and Paris – Le Bourget Airport, the flight took 2 hours and 30 minutes at £21 per passenger. + +On August 25, 1919, the company used DH.16s to pioneer a regular service from Hounslow Heath Aerodrome to Paris's Le Bourget, the first regular international service in the world. The airline soon gained a reputation for reliability, despite problems with bad weather, and began to attract European competition. In November 1919, it won the first British civil airmail contract. Six Royal Air Force Airco DH.9A aircraft were lent to the company, to operate the airmail service between Hawkinge and Cologne. In 1920, they were returned to the Royal Air Force. + +Other British competitors were quick to follow – Handley Page Transport was established in 1919 and used the company's converted wartime Type O/400 bombers with a capacity for 12 passengers, to run a London-Paris passenger service. + +The first French airline was Société des lignes Latécoère, later known as Aéropostale, which started its first service in late 1918 to Spain. The Société Générale des Transports Aériens was created in late 1919, by the Farman brothers and the Farman F.60 Goliath plane flew scheduled services from Toussus-le-Noble to Kenley, near Croydon, England. Another early French airline was the Compagnie des Messageries Aériennes, established in 1919 by Louis-Charles Breguet, offering a mail and freight service between Le Bourget Airport, Paris and Lesquin Airport, Lille. + +The first German airline to use heavier than air aircraft was Deutsche Luft-Reederei established in 1917 which started operating in February 1919. In its first year, the D.L.R. operated regularly scheduled flights on routes with a combined length of nearly 1000 miles. By 1921 the D.L.R. network was more than 3000 km (1865 miles) long, and included destinations in the Netherlands, Scandinavia and the Baltic Republics. Another important German airline was Junkers Luftverkehr, which began operations in 1921. It was a division of the aircraft manufacturer Junkers, which became a separate company in 1924. It operated joint-venture airlines in Austria, Denmark, Estonia, Finland, Hungary, Latvia, Norway, Poland, Sweden and Switzerland. + +The Dutch airline KLM made its first flight in 1920, and is the oldest continuously operating airline in the world. Established by aviator Albert Plesman, it was immediately awarded a "Royal" predicate from Queen Wilhelmina. Its first flight was from Croydon Airport, London to Amsterdam, using a leased Aircraft Transport and Travel DH-16, and carrying two British journalists and a number of newspapers. In 1921, KLM started scheduled services. + +In Finland, the charter establishing Aero O/Y (now Finnair) was signed in the city of Helsinki on 12 September 1923. Junkers F.13 D-335 became the first aircraft of the company, when Aero took delivery of it on 14 March 1924. The first flight was between Helsinki and Tallinn, capital of Estonia, and it took place on 20 March 1924, one week later. + +In the Soviet Union, the Chief Administration of the Civil Air Fleet was established in 1921. One of its first acts was to help found Deutsch-Russische Luftverkehrs A.G. (Deruluft), a German-Russian joint venture to provide air transport from Russia to the West. Domestic air service began around the same time, when Dobrolyot started operations on 15 July 1923 between Moscow and Nizhni Novgorod. Since 1932 all operations had been carried under the name Aeroflot. + +Early European airlines tended to favor comfort – the passenger cabins were often spacious with luxurious interiors – over speed and efficiency. The relatively basic navigational capabilities of pilots at the time also meant that delays due to the weather were commonplace. + +Rationalization + +By the early 1920s, small airlines were struggling to compete, and there was a movement towards increased rationalization and consolidation. In 1924, Imperial Airways was formed from the merger of Instone Air Line Company, British Marine Air Navigation, Daimler Airway and Handley Page Transport, to allow British airlines to compete with stiff competition from French and German airlines that were enjoying heavy government subsidies. The airline was a pioneer in surveying and opening up air routes across the world to serve far-flung parts of the British Empire and to enhance trade and integration. + +The first new airliner ordered by Imperial Airways, was the Handley Page W8f City of Washington, delivered on 3 November 1924. In the first year of operation the company carried 11,395 passengers and 212,380 letters. In April 1925, the film The Lost World became the first film to be screened for passengers on a scheduled airliner flight when it was shown on the London-Paris route. + +Two French airlines also merged to form Air Union on 1 January 1923. This later merged with four other French airlines to become Air France, the country's flagship carrier to this day, on 17 May 1933. + +Germany's Deutsche Lufthansa was created in 1926 by merger of two airlines, one of them Junkers Luftverkehr. Lufthansa, due to the Junkers heritage and unlike most other airlines at the time, became a major investor in airlines outside of Europe, providing capital to Varig and Avianca. German airliners built by Junkers, Dornier, and Fokker were among the most advanced in the world at the time. + +Expansion +In 1926, Alan Cobham surveyed a flight route from the UK to Cape Town, South Africa, following this up with another proving flight to Melbourne, Australia. Other routes to British India and the Far East were also charted and demonstrated at this time. Regular services to Cairo and Basra began in 1927 and were extended to Karachi in 1929. The London-Australia service was inaugurated in 1932 with the Handley Page HP 42 airliners. Further services were opened up to Calcutta, Rangoon, Singapore, Brisbane and Hong Kong passengers departed London on 14 March 1936 following the establishment of a branch from Penang to Hong Kong. + +France began an air mail service to Morocco in 1919 that was bought out in 1927, renamed Aéropostale, and injected with capital to become a major international carrier. In 1933, Aéropostale went bankrupt, was nationalized and merged into Air France. + +Although Germany lacked colonies, it also began expanding its services globally. In 1931, the airship Graf Zeppelin began offering regular scheduled passenger service between Germany and South America, usually every two weeks, which continued until 1937. In 1936, the airship Hindenburg entered passenger service and successfully crossed the Atlantic 36 times before crashing at Lakehurst, New Jersey, on 6 May 1937. In 1938, a weekly air service from Berlin to Kabul, Afghanistan, started operating. + +From February 1934 until World War II began in 1939, Deutsche Lufthansa operated an airmail service from Stuttgart, Germany via Spain, the Canary Islands and West Africa to Natal in Brazil. This was the first time an airline flew across an ocean. + +By the end of the 1930s Aeroflot had become the world's largest airline, employing more than 4,000 pilots and 60,000 other service personnel and operating around 3,000 aircraft (of which 75% were considered obsolete by its own standards). During the Soviet era Aeroflot was synonymous with Russian civil aviation, as it was the only air carrier. It became the first airline in the world to operate sustained regular jet services on 15 September 1956 with the Tupolev Tu-104. + +Deregulation +Deregulation of the European Union airspace in the early 1990s has had substantial effect on the structure of the industry there. The shift towards 'budget' airlines on shorter routes has been significant. Airlines such as EasyJet and Ryanair have often grown at the expense of the traditional national airlines. + +There has also been a trend for these national airlines themselves to be privatized such as has occurred for Aer Lingus and British Airways. Other national airlines, including Italy's Alitalia, suffered – particularly with the rapid increase of oil prices in early 2008. + +Finnair, the largest airline of Finland, had no fatal or hull-loss accidents since 1963, and is recognized for its safety. + +United States + +Early development + +Tony Jannus conducted the United States' first scheduled commercial airline flight on January 1, 1914 for the St. Petersburg-Tampa Airboat Line. The 23-minute flight traveled between St. Petersburg, Florida and Tampa, Florida, passing some above Tampa Bay in Jannus' Benoist XIV wood and muslin biplane flying boat. His passenger was a former mayor of St. Petersburg, who paid $400 for the privilege of sitting on a wooden bench in the open cockpit. The Airboat line operated for about four months, carrying more than 1,200 passengers who paid $5 each. Chalk's International Airlines began service between Miami and Bimini in the Bahamas in February 1919. Based in Ft. Lauderdale, Chalk's claimed to be the oldest continuously operating airline in the United States until its closure in 2008. + +Following World War I, the United States found itself swamped with aviators. Many decided to take their war-surplus aircraft on barnstorming campaigns, performing aerobatic maneuvers to woo crowds. In 1918, the United States Postal Service won the financial backing of Congress to begin experimenting with air mail service, initially using Curtiss Jenny aircraft that had been procured by the United States Army Air Service. Private operators were the first to fly the mail but due to numerous accidents the US Army was tasked with mail delivery. During the Army's involvement they proved to be too unreliable and lost their air mail duties. By the mid-1920s, the Postal Service had developed its own air mail network, based on a transcontinental backbone between New York City and San Francisco. To supplement this service, they offered twelve contracts for spur routes to independent bidders. Some of the carriers that won these routes would, through time and mergers, evolve into Pan Am, Delta Air Lines, Braniff Airways, American Airlines, United Airlines (originally a division of Boeing), Trans World Airlines, Northwest Airlines, and Eastern Air Lines. + +Service during the early 1920s was sporadic: most airlines at the time were focused on carrying bags of mail. In 1925, however, the Ford Motor Company bought out the Stout Aircraft Company and began construction of the all-metal Ford Trimotor, which became the first successful American airliner. With a 12-passenger capacity, the Trimotor made passenger service potentially profitable. Air service was seen as a supplement to rail service in the American transportation network. + +At the same time, Juan Trippe began a crusade to create an air network that would link America to the world, and he achieved this goal through his airline, Pan Am, with a fleet of flying boats that linked Los Angeles to Shanghai and Boston to London. Pan Am and Northwest Airways (which began flights to Canada in the 1920s) were the only U.S. airlines to go international before the 1940s. + +With the introduction of the Boeing 247 and Douglas DC-3 in the 1930s, the U.S. airline industry was generally profitable, even during the Great Depression. This trend continued until the beginning of World War II. + +Since 1945 + +World War II, like World War I, brought new life to the airline industry. Many airlines in the Allied countries were flush from lease contracts to the military, and foresaw a future explosive demand for civil air transport, for both passengers and cargo. They were eager to invest in the newly emerging flagships of air travel such as the Boeing Stratocruiser, Lockheed Constellation, and Douglas DC-6. Most of these new aircraft were based on American bombers such as the B-29, which had spearheaded research into new technologies such as pressurization. Most offered increased efficiency from both added speed and greater payload. + +In the 1950s, the De Havilland Comet, Boeing 707, Douglas DC-8, and Sud Aviation Caravelle became the first flagships of the Jet Age in the West, while the Eastern bloc had Tupolev Tu-104 and Tupolev Tu-124 in the fleets of state-owned carriers such as Czechoslovak ČSA, Soviet Aeroflot and East-German Interflug. The Vickers Viscount and Lockheed L-188 Electra inaugurated turboprop transport. + +On 4 October 1958, British Overseas Airways Corporation started transatlantic flights between London Heathrow and New York Idlewild with a Comet 4, and Pan Am followed on 26 October with a Boeing 707 service between New York and Paris. + +The next big boost for the airlines would come in the 1970s, when the Boeing 747, McDonnell Douglas DC-10, and Lockheed L-1011 inaugurated widebody ("jumbo jet") service, which is still the standard in international travel. The Tupolev Tu-144 and its Western counterpart, Concorde, made supersonic travel a reality. Concorde first flew in 1969 and operated through 2003. In 1972, Airbus began producing Europe's most commercially successful line of airliners to date. The added efficiencies for these aircraft were often not in speed, but in passenger capacity, payload, and range. Airbus also features modern electronic cockpits that were common across their aircraft to enable pilots to fly multiple models with minimal cross-training. + +Deregulation + +The 1978 U.S. airline industry deregulation lowered federally controlled barriers for new airlines just as a downturn in the nation's economy occurred. New start-ups entered during the downturn, during which time they found aircraft and funding, contracted hangar and maintenance services, trained new employees, and recruited laid-off staff from other airlines. + +Major airlines dominated their routes through aggressive pricing and additional capacity offerings, often swamping new start-ups. In the place of high barriers to entry imposed by regulation, the major airlines implemented an equally high barrier called loss leader pricing. In this strategy an already established and dominant airline stomps out its competition by lowering airfares on specific routes, below the cost of operating on it, choking out any chance a start-up airline may have. The industry side effect is an overall drop in revenue and service quality. Since deregulation in 1978 the average domestic ticket price has dropped by 40%. So has airline employee pay. By incurring massive losses, the airlines of the USA now rely upon a scourge of cyclical Chapter 11 bankruptcy proceedings to continue doing business. America West Airlines (which has since merged with US Airways) remained a significant survivor from this new entrant era, as dozens, even hundreds, have gone under. + +In many ways, the biggest winner in the deregulated environment was the air passenger. Although not exclusively attributable to deregulation, indeed the U.S. witnessed an explosive growth in demand for air travel. Many millions who had never or rarely flown before became regular fliers, even joining frequent flyer loyalty programs and receiving free flights and other benefits from their flying. New services and higher frequencies meant that business fliers could fly to another city, do business, and return the same day, from almost any point in the country. Air travel's advantages put long-distance intercity railroad travel and bus lines under pressure, with most of the latter having withered away, whilst the former is still protected under nationalization through the continuing existence of Amtrak. + +By the 1980s, almost half of the total flying in the world took place in the U.S., and today the domestic industry operates over 10,000 daily departures nationwide. + +Toward the end of the century, a new style of low cost airline emerged, offering a no-frills product at a lower price. Southwest Airlines, JetBlue, AirTran Airways, Skybus Airlines and other low-cost carriers began to represent a serious challenge to the so-called "legacy airlines", as did their low-cost counterparts in many other countries. Their commercial viability represented a serious competitive threat to the legacy carriers. However, of these, ATA and Skybus have since ceased operations. + +Increasingly since 1978, US airlines have been reincorporated and spun off by newly created and internally led management companies, and thus becoming nothing more than operating units and subsidiaries with limited financially decisive control. Among some of these holding companies and parent companies which are relatively well known, are the UAL Corporation, along with the AMR Corporation, among a long list of airline holding companies sometime recognized worldwide. Less recognized are the private-equity firms which often seize managerial, financial, and board of directors control of distressed airline companies by temporarily investing large sums of capital in air carriers, to rescheme an airlines assets into a profitable organization or liquidating an air carrier of their profitable and worthwhile routes and business operations. + +Thus the last 50 years of the airline industry have varied from reasonably profitable, to devastatingly depressed. As the first major market to deregulate the industry in 1978, U.S. airlines have experienced more turbulence than almost any other country or region. In fact, no U.S. legacy carrier survived bankruptcy-free. Among the outspoken critics of deregulation, former CEO of American Airlines, Robert Crandall has publicly stated: "Chapter 11 bankruptcy protection filing shows airline industry deregulation was a mistake." + +Bailout +Congress passed the Air Transportation Safety and System Stabilization Act (P.L. 107–42) in response to a severe liquidity crisis facing the already-troubled airline industry in the aftermath of the September 11 attacks. Through the ATSB Congress sought to provide cash infusions to carriers for both the cost of the four-day federal shutdown of the airlines and the incremental losses incurred through December 31, 2001, as a result of the terrorist attacks. This resulted in the first government bailout of the 21st century. Between 2000 and 2005 US airlines lost $30 billion with wage cuts of over $15 billion and 100,000 employees laid off. + +In recognition of the essential national economic role of a healthy aviation system, Congress authorized partial compensation of up to $5 billion in cash subject to review by the U.S. Department of Transportation and up to $10 billion in loan guarantees subject to review by a newly created Air Transportation Stabilization Board (ATSB). The applications to DOT for reimbursements were subjected to rigorous multi-year reviews not only by DOT program personnel but also by the Government Accountability Office and the DOT Inspector General. + +Ultimately, the federal government provided $4.6 billion in one-time, subject-to-income-tax cash payments to 427 U.S. air carriers, with no provision for repayment, essentially a gift from the taxpayers. (Passenger carriers operating scheduled service received approximately $4 billion, subject to tax.) In addition, the ATSB approved loan guarantees to six airlines totaling approximately $1.6 billion. Data from the U.S. Treasury Department show that the government recouped the $1.6 billion and a profit of $339 million from the fees, interest and purchase of discounted airline stock associated with loan guarantees. + +The three largest major carriers and Southwest Airlines control 70% of the U.S. passenger market. + +Asia + +Although Philippine Airlines (PAL) was officially founded on February 26, 1941, its license to operate as an airliner was derived from merged Philippine Aerial Taxi Company (PATCO) established by mining magnate Emmanuel N. Bachrach on 3 December 1930, making it Asia's oldest scheduled carrier still in operation. Commercial air service commenced three weeks later from Manila to Baguio, making it Asia's first airline route. Bachrach's death in 1937 paved the way for its eventual merger with Philippine Airlines in March 1941 and made it Asia's oldest airline. It is also the oldest airline in Asia still operating under its current name. Bachrach's majority share in PATCO was bought by beer magnate Andres R. Soriano in 1939 upon the advice of General Douglas MacArthur and later merged with newly formed Philippine Airlines with PAL as the surviving entity. Soriano has controlling interest in both airlines before the merger. PAL restarted service on 15 March 1941, with a single Beech Model 18 NPC-54 aircraft, which started its daily services between Manila (from Nielson Field) and Baguio, later to expand with larger aircraft such as the DC-3 and Vickers Viscount. + +Cathay Pacific was one of the first airlines to be launched among the other Asian countries in 1946 along with Asiana Airlines, which later joined in 1988. The license to operate as an airliner was granted by the federal government body after reviewing the necessity at the national assembly. The Hanjin occupies the largest ownership of Korean Air as well as few low-budget airlines as of now. Korean Air is one of the four founders of SkyTeam, which was established in 2000. Asiana Airlines joined Star Alliance in 2003. Korean Air and Asiana Airlines comprise one of the largest combined airline miles and number of passenger served at the regional market of Asian airline industry + +India was also one of the first countries to embrace civil aviation. One of the first Asian airline companies was Air India, which was founded as Tata Airlines in 1932, a division of Tata Sons Ltd. (now Tata Group). The airline was founded by India's leading industrialist, JRD Tata. On 15 October 1932, J. R. D. Tata himself flew a single engined De Havilland Puss Moth carrying air mail (postal mail of Imperial Airways) from Karachi to Bombay via Ahmedabad. The aircraft continued to Madras via Bellary piloted by Royal Air Force pilot Nevill Vintcent. Tata Airlines was also one of the world's first major airlines which began its operations without any support from the Government. + +With the outbreak of World War II, the airline presence in Asia came to a relative halt, with many new flag carriers donating their aircraft for military aid and other uses. Following the end of the war in 1945, regular commercial service was restored in India and Tata Airlines became a public limited company on 29 July 1946, under the name Air India. After the independence of India, 49% of the airline was acquired by the Government of India. In return, the airline was granted status to operate international services from India as the designated flag carrier under the name Air India International. + +On 31 July 1946, a chartered Philippine Airlines (PAL) DC-4 ferried 40 American servicemen to Oakland, California, from Nielson Airport in Makati with stops in Guam, Wake Island, Johnston Atoll and Honolulu, Hawaii, making PAL the first Asian airline to cross the Pacific Ocean. A regular service between Manila and San Francisco was started in December. It was during this year that the airline was designated as the flag carrier of Philippines. + +During the era of decolonization, newly born Asian countries started to embrace air transport. Among the first Asian carriers during the era were Cathay Pacific of Hong Kong (founded in September 1946), Orient Airways (later Pakistan International Airlines; founded in October 1946), Air Ceylon (later SriLankan Airlines; founded in 1947), Malayan Airways Limited in 1947 (later Singapore and Malaysia Airlines), El Al in Israel in 1948, Garuda Indonesia in 1949, Japan Airlines in 1951, Thai Airways in 1960, and Korean National Airlines in 1947. + +Singapore Airlines had won quality awards. + +Latin America and Caribbean + +Among the first countries to have regular airlines in Latin America and the Caribbean were Bolivia with Lloyd Aéreo Boliviano, Cuba with Cubana de Aviación, Colombia with Avianca (the first airline established in the Americas), Argentina with Aerolíneas Argentinas, Chile with LAN Chile (today LATAM Airlines), Brazil with Varig, the Dominican Republic with Dominicana de Aviación, Mexico with Mexicana de Aviación, Trinidad and Tobago with BWIA West Indies Airways (today Caribbean Airlines), Venezuela with Aeropostal, Puerto Rico with Puertorriquena; and TACA based in El Salvador and representing several airlines of Central America (Costa Rica, Guatemala, Honduras and Nicaragua). All the previous airlines started regular operations well before World War II. Puerto Rican commercial airlines such as Prinair, Oceanair, Fina Air and Vieques Air Link came much after the second world war, as did several others from other countries like Mexico's Interjet and Volaris, Venezuela's Aserca Airlines and others. + +The air travel market has evolved rapidly over recent years in Latin America. Some industry estimates indicated in 2011 that over 2,000 new aircraft will begin service over the next five years in this region. + +These airlines serve domestic flights within their countries, as well as connections within Latin America and also overseas flights to North America, Europe, Australia, and Asia. + +Only five airline groups – Avianca, Panama's Copa, Mexico's Volaris, the Irelandia group and LATAM Airlines – have international subsidiaries and cover many destinations within the Americas as well as major hubs in other continents. LATAM with Chile as the central operation along with Peru, Ecuador, Colombia, Brazil and Argentina and formerly with some operations in the Dominican Republic. The Avianca group has its main operation in Colombia based around the hub in Bogotá, Colombia, as well as subsidiaries in various Latin American countries with hubs in San Salvador, El Salvador, as well as Lima, Peru, with a smaller operation in Ecuador. Copa has subsidiaries Copa Airlines Colombia and Wingo, both in Colombia, while Volaris of Mexico has Volaris Costa Rica and Volaris El Salvador, and the Irelandia group formerly included Viva Aerobus of Mexico; it now includes Viva Colombia and Viva Air Peru. + +Regulation + +National + +Many countries have national airlines that the government owns and operates. Fully private airlines are subject to much government regulation for economic, political, and safety concerns. For instance, governments often intervene to halt airline labor actions to protect the free flow of people, communications, and goods between different regions without compromising safety. + +The United States, Australia, and to a lesser extent Brazil, Mexico, India, the United Kingdom, and Japan have "deregulated" their airlines. In the past, these governments dictated airfares, route networks, and other operational requirements for each airline. Since deregulation, airlines have been largely free to negotiate their own operating arrangements with different airports, enter and exit routes easily, and to levy airfares and supply flights according to market demand. The entry barriers for new airlines are lower in a deregulated market, and so the U.S. has seen hundreds of airlines start up (sometimes for only a brief operating period). This has produced far greater competition than before deregulation in most markets. The added competition, together with pricing freedom, means that new entrants often take market share with highly reduced rates that, to a limited degree, full service airlines must match. This is a major constraint on profitability for established carriers, which tend to have a higher cost base. + +As a result, profitability in a deregulated market is uneven for most airlines. These forces have caused some major airlines to go out of business, in addition to most of the poorly established new entrants. + +In the United States, the airline industry is dominated by four large firms. Because of industry consolidation, after fuel prices dropped considerably in 2015, very little of the savings were passed on to consumers. + +International + +Groups such as the International Civil Aviation Organization establish worldwide standards for safety and other vital concerns. Most international air traffic is regulated by bilateral agreements between countries, which designate specific carriers to operate on specific routes. The model of such an agreement was the Bermuda Agreement between the US and UK following World War II, which designated airports to be used for transatlantic flights and gave each government the authority to nominate carriers to operate routes. + +Bilateral agreements are based on the "freedoms of the air", a group of generalized traffic rights ranging from the freedom to overfly a country to the freedom to provide domestic flights within a country (a very rarely granted right known as cabotage). Most agreements permit airlines to fly from their home country to designated airports in the other country: some also extend the freedom to provide continuing service to a third country, or to another destination in the other country while carrying passengers from overseas. + +In the 1990s, "open skies" agreements became more common. These agreements take many of these regulatory powers from state governments and open up international routes to further competition. Open skies agreements have met some criticism, particularly within the European Union, whose airlines would be at a comparative disadvantage with the United States' because of cabotage restrictions. + +Economy + +In 2017, 4.1 billion passengers have been carried by airlines in 41.9 million commercial scheduled flights (an average payload of passengers), for 7.75 trillion passenger kilometres (an average trip of km) over 45,091 airline routes served globally. In 2016, air transport generated $704.4 billion of revenue in 2016, employed 10.2 million workers, supported 65.5 million jobs and $2.7 trillion of economic activity: 3.6% of the global GDP. + +In July 2016, the total weekly airline capacity was 181.1 billion Available Seat Kilometers (+6.9% compared to July 2015): 57.6bn in Asia-Pacific, 47.7bn in Europe, 46.2bn in North America, 12.2bn in Middle East, 12.0bn in Latin America and 5.4bn in Africa. + +Costs + +Airlines have substantial fixed and operating costs to establish and maintain air services: labor, fuel, airplanes, engines, spares and parts, IT services and networks, airport equipment, airport handling services, booking commissions, advertising, catering, training, aviation insurance and other costs. Thus all but a small percentage of the income from ticket sales is paid out to a wide variety of external providers or internal cost centers. + +Moreover, the industry is structured so that airlines often act as tax collectors. Airline fuel is untaxed because of a series of treaties existing between countries. Ticket prices include a number of fees, taxes and surcharges beyond the control of airlines. Airlines are also responsible for enforcing government regulations. If airlines carry passengers without proper documentation on an international flight, they are responsible for returning them back to the original country. + +Analysis of the 1992–1996 period shows that every player in the air transport chain is far more profitable than the airlines, who collect and pass through fees and revenues to them from ticket sales. While airlines as a whole earned 6% return on capital employed (2–3.5% less than the cost of capital), airports earned 10%, catering companies 10–13%, handling companies 11–14%, aircraft lessors 15%, aircraft manufacturers 16%, and global distribution companies more than 30%. + +There has been continuing cost competition from low cost airlines. Many companies emulate Southwest Airlines in various respects. The lines between full-service and low-cost airlines have become blurred – e.g., with most "full service" airlines introducing baggage check fees despite Southwest not doing so. + +Many airlines in the U.S. and elsewhere have experienced business difficulty. U.S. airlines that have declared Chapter 11 bankruptcy since 1990 have included American Airlines, Continental Airlines (twice), Delta Air Lines, Northwest Airlines, Pan Am, United Airlines and US Airways (twice). + +Where an airline has established an engineering base at an airport, then there may be considerable economic advantages in using that same airport as a preferred focus (or "hub") for its scheduled flights. + +Fuel hedging is a contractual tool used by transportation companies like airlines to reduce their exposure to volatile and potentially rising fuel costs. Several low-cost carriers such as Southwest Airlines adopt this practice. Southwest is credited with maintaining strong business profits between 1999 and the early 2000s due to its fuel hedging policy. Many other airlines are replicating Southwest's hedging policy to control their fuel costs. + +Operating costs for US major airlines are primarily aircraft operating expense including jet fuel, aircraft maintenance, depreciation and aircrew for 44%, servicing expense for 29% (traffic 11%, passenger 11% and aircraft 7%), 14% for reservations and sales and 13% for overheads (administration 6% and advertising 2%). An average US major Boeing 757-200 flies stages 11.3 block hours per day and costs $2,550 per block hour: $923 of ownership, $590 of maintenance, $548 of fuel and $489 of crew; or $13.34 per 186 seats per block hour. For a Boeing 737-500, a low-cost carrier like Southwest have lower operating costs at $1,526 than a full service one like United at $2,974, and higher productivity with 399,746 ASM per day against 264,284, resulting in a unit cost of $cts/ASM against $cts/ASM. + +McKinsey observes that "newer technology, larger aircraft, and increasingly efficient operations continually drive down the cost of running an airline", from nearly 40 US cents per ASK at the beginning of the jet age, to just above 10 cents since 2000. Those improvements were passed onto the customer due to high competition: fares have been falling throughout the history of airlines. + +Revenue + +Airlines assign prices to their services in an attempt to maximize profitability. The pricing of airline tickets has become increasingly complicated over the years and is now largely determined by computerized yield management systems. + +Because of the complications in scheduling flights and maintaining profitability, airlines have many loopholes that can be used by the knowledgeable traveler. Many of these airfare secrets are becoming more and more known to the general public, so airlines are forced to make constant adjustments. + +Most airlines use differentiated pricing, a form of price discrimination, to sell air services at varying prices simultaneously to different segments. Factors influencing the price include the days remaining until departure, the booked load factor, the forecast of total demand by price point, competitive pricing in force, and variations by day of week of departure and by time of day. Carriers often accomplish this by dividing each cabin of the aircraft (first, business and economy) into a number of travel classes for pricing purposes. + +A complicating factor is that of origin-destination control ("O&D control"). Someone purchasing a ticket from Melbourne to Sydney (as an example) for A$200 is competing with someone else who wants to fly Melbourne to Los Angeles through Sydney on the same flight, and who is willing to pay A$1400. Should the airline prefer the $1400 passenger, or the $200 passenger plus a possible Sydney-Los Angeles passenger willing to pay $1300? Airlines have to make hundreds of thousands of similar pricing decisions daily. + +The advent of advanced computerized reservations systems in the late 1970s, most notably Sabre, allowed airlines to easily perform cost-benefit analyses on different pricing structures, leading to almost perfect price discrimination in some cases (that is, filling each seat on an aircraft at the highest price that can be charged without driving the consumer elsewhere). + +The intense nature of airfare pricing has led to the term "fare war" to describe efforts by airlines to undercut other airlines on competitive routes. Through computers, new airfares can be published quickly and efficiently to the airlines' sales channels. For this purpose the airlines use the Airline Tariff Publishing Company (ATPCO), who distribute latest fares for more than 500 airlines to Computer Reservation Systems across the world. + +The extent of these pricing phenomena is strongest in "legacy" carriers. In contrast, low fare carriers usually offer pre-announced and simplified price structure, and sometimes quote prices for each leg of a trip separately. + +Computers also allow airlines to predict, with some accuracy, how many passengers will actually fly after making a reservation to fly. This allows airlines to overbook their flights enough to fill the aircraft while accounting for "no-shows", but not enough (in most cases) to force paying passengers off the aircraft for lack of seats, stimulative pricing for low demand flights coupled with overbooking on high demand flights can help reduce this figure. This is especially crucial during tough economic times as airlines undertake massive cuts to ticket prices to retain demand. + +Over January/February 2018, the cheapest airline surveyed by price comparator rome2rio was now-defunct Tigerair Australia with $0.06/km followed by AirAsia X with $0.07/km, while the most expensive was Charterlines, Inc. with $1.26/km followed by Buddha Air with $1.18/km. + +For the IATA, the global airline industry revenue was $754 billion in 2017 for a $38.4 billion collective profit, and should rise by 10.7% to $834 billion in 2018 for a $33.8 billion profit forecast, down by 12% due to rising jet fuel and labor costs. + +The demand for air transport will be less elastic for longer flights than for shorter flights, and more elastic for leisure travel than for business travel. + +Airlines often have a strong seasonality, with traffic low in winter and peaking in summer. In Europe the most extreme market are the Greek islands with July/August having more than ten times the winter traffic, as Jet2 is the most seasonal among low-cost carriers with July having seven times the January traffic, whereas legacy carriers are much less with only 85/115% variability. + +Assets and financing + +Airline financing is quite complex, since airlines are highly leveraged operations. Not only must they purchase (or lease) new airliner bodies and engines regularly, they must make major long-term fleet decisions with the goal of meeting the demands of their markets while producing a fleet that is relatively economical to operate and maintain; comparably Southwest Airlines and their reliance on a single airplane type (the Boeing 737 and derivatives), with the now defunct Eastern Air Lines which operated 17 different aircraft types, each with varying pilot, engine, maintenance, and support needs. + +A second financial issue is that of hedging oil and fuel purchases, which are usually second only to labor in its relative cost to the company. However, with the current high fuel prices it has become the largest cost to an airline. Legacy airlines, compared with new entrants, have been hit harder by rising fuel prices partly due to the running of older, less fuel efficient aircraft. While hedging instruments can be expensive, they can easily pay for themselves many times over in periods of increasing fuel costs, such as in the 2000–2005 period. + +In view of the congestion apparent at many international airports, the ownership of slots at certain airports (the right to take-off or land an aircraft at a particular time of day or night) has become a significant tradable asset for many airlines. Clearly take-off slots at popular times of the day can be critical in attracting the more profitable business traveler to a given airline's flight and in establishing a competitive advantage against a competing airline. + +If a particular city has two or more airports, market forces will tend to attract the less profitable routes, or those on which competition is weakest, to the less congested airport, where slots are likely to be more available and therefore cheaper. For example, Reagan National Airport attracts profitable routes due partly to its congestion, leaving less-profitable routes to Baltimore-Washington International Airport and Dulles International Airport. + +Other factors, such as surface transport facilities and onward connections, will also affect the relative appeal of different airports and some long-distance flights may need to operate from the one with the longest runway. For example, LaGuardia Airport is the preferred airport for most of Manhattan due to its proximity, while long-distance routes must use John F. Kennedy International Airport's longer runways. + +Airline Alliances +See Main Article: https://en.wikipedia.org/wiki/Airline_alliance + +The first airline alliance was formed in the 1930s when Pan Am and its subsidiary, Panair do Brasil, agreed to codeshare routes in Latin America when they overlapped with each other. + +Codesharing involves one airline selling tickets for another airline's flights under its own airline code. An early example of this was Japan Airlines' (JAL) codesharing partnership with Aeroflot in the 1960s on Tokyo–Moscow flights; Aeroflot operated the flights using Aeroflot aircraft, but JAL sold tickets for the flights as if they were JAL flights. Another example was the Austrian–Sabena partnership on the Vienna–Brussels–New York/JFK route during the late '60s, using a Sabena Boeing 707 with Austrian livery. + +Since airline reservation requests are often made by city-pair (such as "show me flights from Chicago to Düsseldorf"), an airline that can codeshare with another airline for a variety of routes might be able to be listed as indeed offering a Chicago–Düsseldorf flight. The passenger is advised however, that airline no. 1 operates the flight from say Chicago to Amsterdam (for example), and airline no. 2 operates the continuing flight (on a different airplane, sometimes from another terminal) to Düsseldorf. Thus the primary rationale for code sharing is to expand one's service offerings in city-pair terms to increase sales. + +A more recent development is the airline alliance, which became prevalent in the late 1990s. These alliances can act as virtual mergers to get around government restrictions. The largest are Star Alliance, SkyTeam and Oneworld, and these accounted for over 60% of global commercial air traffic . Alliances of airlines coordinate their passenger service programs (such as lounges and frequent-flyer programs), offer special interline tickets and often engage in extensive codesharing (sometimes systemwide). These are increasingly integrated business combinations—sometimes including cross-equity arrangements—in which products, service standards, schedules, and airport facilities are standardized and combined for higher efficiency. One of the first airlines to start an alliance with another airline was KLM, who partnered with Northwest Airlines. Both airlines later entered the SkyTeam alliance after the fusion of KLM and Air France in 2004. + +Often the companies combine IT operations, or purchase fuel and aircraft as a bloc to achieve higher bargaining power. However, the alliances have been most successful at purchasing invisible supplies and services, such as fuel. Airlines usually prefer to purchase items visible to their passengers to differentiate themselves from local competitors. If an airline's main domestic competitor flies Boeing airliners, then the airline may prefer to use Airbus aircraft regardless of what the rest of the alliance chooses. + +Largest airlines + +The world's largest airlines can be defined in several ways. , American Airlines Group was the largest by fleet size, passengers carried and revenue passenger mile. Delta Air Lines was the largest by revenue, assets value and market capitalization. Lufthansa Group was the largest by number of employees, FedEx Express by freight tonne-kilometres, Turkish Airlines by number of countries served and UPS Airlines by number of destinations served (though United Airlines was the largest passenger airline by number of destinations served). + +State support +Historically, air travel has survived largely through state support, whether in the form of equity or subsidies. The airline industry as a whole has made a cumulative loss during its 100-year history. + +One argument is that positive externalities, such as higher growth due to global mobility, outweigh the microeconomic losses and justify continuing government intervention. A historically high level of government intervention in the airline industry can be seen as part of a wider political consensus on strategic forms of transport, such as highways and railways, both of which receive public funding in most parts of the world. Although many countries continue to operate state-owned or parastatal airlines, many large airlines today are privately owned and are therefore governed by microeconomic principles to maximize shareholder profit. + +In December 1991, the collapse of Pan Am, an airline often credited for shaping the international airline industry, highlighted the financial complexities faced by major airline companies. + +Following the 1978 deregulation, U.S. carriers did not manage to make an aggregate profit for 12 years in 31, including four years where combined losses amounted to $10 billion, but rebounded with eight consecutive years of profits since 2010, including its four with over $10 billion profits. They drop loss-making routes, avoid fare wars and market share battles, limit capacity growth, add hub feed with regional jets to increase their profitability. They change schedules to create more connections, buy used aircraft, reduce international frequencies and leverage partnerships to optimize capacities and benefit from overseas connectivity. + +Environment + +Aircraft engines emit noise pollution, gases and particulate emissions, and contribute to global dimming. + +Growth of the industry in recent years raised a number of ecological questions. + +Domestic air transport grew in China at 15.5 percent annually from 2001 to 2006. The rate of air travel globally increased at 3.7 percent per year over the same time. In the EU greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. However it must be compared with the flights increase, only in UK, between 1990 and 2006 terminal passengers increased from 100 000 thousands to 250 000 thousands., according to AEA reports every year, 750 million passengers travel by European airlines, which also share 40% of merchandise value in and out of Europe. Without even pressure from "green activists", targeting lower ticket prices, generally, airlines do what is possible to cut the fuel consumption (and gas emissions connected therewith). Further, according to some reports, it can be concluded that the last piston-powered aircraft were as fuel-efficient as the average jet in 2005. + +Despite continuing efficiency improvements from the major aircraft manufacturers, the expanding demand for global air travel has resulted in growing greenhouse gas (GHG) emissions. Currently, the aviation sector, including US domestic and global international travel, make approximately 1.6 percent of global anthropogenic GHG emissions per annum. North America accounts for nearly 40 percent of the world's GHG emissions from aviation fuel use. + + emissions from the jet fuel burned per passenger on an average airline flight is about 353 kilograms (776 pounds). Loss of natural habitat potential associated with the jet fuel burned per passenger on a airline flight is estimated to be 250 square meters (2700 square feet). + +In the context of climate change and peak oil, there is a debate about possible taxation of air travel and the inclusion of aviation in an emissions trading scheme, with a view to ensuring that the total external costs of aviation are taken into account. + +The airline industry is responsible for about 11 percent of greenhouse gases emitted by the U.S. transportation sector. Boeing estimates that biofuels could reduce flight-related greenhouse-gas emissions by 60 to 80 percent. The solution would be blending algae fuels with existing jet fuel: + Boeing and Air New Zealand are collaborating with leading Brazilian biofuel maker Tecbio, New Zealand's Aquaflow Bionomic and other jet biofuel developers around the world. + Virgin Atlantic and Virgin Green Fund are looking into the technology as part of a biofuel initiative. + KLM has made the first commercial flight with biofuel in 2009. + +There are projects on electric aircraft, and some of which are fully operational as of 2013. + +Call signs + +Each operator of a scheduled or charter flight uses an airline call sign when communicating with airports or air traffic control. Most of these call-signs are derived from the airline's trade name, but for reasons of history, marketing, or the need to reduce ambiguity in spoken English (so that pilots do not mistakenly make navigational decisions based on instructions issued to a different aircraft), some airlines and air forces use call-signs less obviously connected with their trading name. For example, British Airways uses a Speedbird call-sign, named after the logo of one of its predecessors, BOAC, while SkyEurope used Relax. + +Personnel + +The various types of airline personnel include flight crew, responsible for the operation of the aircraft. Flight crew members include: pilots (captain and first officer: some older aircraft also required a flight engineer and/or a navigator); flight attendants (led by a purser on larger aircraft); In-flight security personnel on some airlines (most notably El Al) + +Groundcrew, responsible for operations at airports, include Aerospace and avionics engineers responsible for certifying the aircraft for flight and management of aircraft maintenance; Aerospace engineers, responsible for airframe, powerplant and electrical systems maintenance; Avionics engineers responsible for avionics and instruments maintenance; Airframe and powerplant technicians; Electric System technicians, responsible for maintenance of electrical systems; Flight dispatchers; Baggage handlers; Ramp Agents; Remote centralized weight and balancing; Gate agents; Ticket agents; Passenger service agents (such as airline lounge employees); Reservation agents, usually (but not always) at facilities outside the airport; Crew schedulers. + +Airlines follow a corporate structure where each broad area of operations (such as maintenance, flight operations (including flight safety), and passenger service) is supervised by a vice president. Larger airlines often appoint vice presidents to oversee each of the airline's hubs as well. Airlines employ lawyers to deal with regulatory procedures and other administrative tasks. + +Trends + +The pattern of ownership has been privatized since the mid-1980s, that is, the ownership has gradually changed from governments to private and individual sectors or organizations. This occurs as regulators permit greater freedom and non-government ownership, in steps that are usually decades apart. This pattern is not seen for all airlines in all regions. Many major airlines operating between the 1940s and 1980s were government-owned or government-established. However, most airlines from the earliest days of air travel in the 1920s and 1930s were personal businesses. + +Growth rates are not consistent in all regions, but countries with a deregulated airline industry have more competition and greater pricing freedom. This results in lower fares and sometimes dramatic spurts in traffic growth. The U.S., Australia, Canada, Japan, Brazil, India and other markets exhibit this trend. The industry has been observed to be cyclical in its financial performance. Four or five years of poor earnings precede five or six years of improvement. But profitability even in the good years is generally low, in the range of 2–3% net profit after interest and tax. In times of profit, airlines lease new generations of airplanes and upgrade services in response to higher demand. Since 1980, the industry has not earned back the cost of capital during the best of times. Conversely, in bad times losses can be dramatically worse. Warren Buffett in 1999 said "the money that had been made since the dawn of aviation by all of this country's airline companies was zero. Absolutely zero." + +As in many mature industries, consolidation is a trend. Airline groupings may consist of limited bilateral partnerships, long-term, multi-faceted alliances between carriers, equity arrangements, mergers, or takeovers. Since governments often restrict ownership and merger between companies in different countries, most consolidation takes place within a country. In the U.S., over 200 airlines have merged, been taken over, or gone out of business since the Airline Deregulation Act in 1978. Many international airline managers are lobbying their governments to permit greater consolidation to achieve higher economy and efficiency. + +Types +There are several types of passenger airlines, mainly + + Mainline airlines operate flights by the airline's main operating unit, rather than by regional affiliates or subsidiaries + Regional airlines, non-"mainline" airlines that operate regional aircraft; regionals typically operate over shorter non-intercontinental distances, often as feeder services for legacy mainline networks + Low-cost carriers, giving a "basic", "no-frills" and perceived inexpensive service + Business class airline, an airline aimed at the business traveler, featuring all business class seating and amenities + Charter airlines, operating outside regular schedule intervals + Flag carriers, the historically nationally owned airlines that were considered representative of the country overseas. + Legacy carriers, US carriers that predate the Airline Deregulation Act of 1978 + Major airlines of the United States, airlines with at least $1 billion in revenues + +See also + +Related lists + +References + +Bibliography + "A history of the world's airlines", R.E.G.

Founded in 1977 from a merger of the Australia Party and the New Liberal Movement, both of which were descended from Liberal Party dissenting splinter groups, it was Australia's largest minor party from its formation in 1977 through to 2004 and frequently held the balance of power in the Senate during that time. + +The Democrats' inaugural leader was Don Chipp, a former Liberal cabinet minister, who famously promised to "keep the bastards honest". At the 1977 federal election, the Democrats polled 11.1 percent of the Senate vote and secured two seats. The party would retain a presence in the Senate for the next 30 years, at its peak (between 1999 and 2002) holding nine out of 76 seats, though never securing a seat in the lower house. Due to the party's numbers in the Senate, both Liberal and Labor governments required the assistance of the Democrats to pass contentious legislation. Ideologically, the Democrats were usually regarded as centrists, occupying the political middle ground between the Liberal Party and the Labor Party. + +Over three decades, the Australian Democrats achieved representation in the legislatures of the ACT, South Australia, New South Wales, Western Australia and Tasmania as well as Commonwealth Senate seats in all six states. However, at the 2004 and 2007 federal elections, all seven of its Senate seats were lost as the party's share of the vote collapsed. This was largely attributed to party leader Meg Lees' decision to pass the Howard government's goods and services tax, which led to several years of popular recriminations and party infighting that destroyed the Democrats' reputation as competent overseers of legislation. The last remaining Democrat State parliamentarian, David Winderlich, left the party and was defeated as an independent in 2010. + +The party was formally deregistered in 2016 for not having the required 500 members. In 2018 the Democrats merged with CountryMinded, a small, also unregistered agrarian political party, and later that year the party's constitution was radically rewritten to establish "top-down" governance and de-emphasize the principle of participatory democracy. On 7 April 2019 the party regained registration with the Australian Electoral Commission. + +As of 2022, the national president of the party is former senator and parliamentary leader Lyn Allison. + +History + +1977–1986: Foundation and Don Chipp's leadership +The Australian Democrats were formed in May 1977 from an amalgamation of the Australia Party and the New Liberal Movement. The two groups found a common basis for a new political movement in the widespread discontent with the two major parties. Former Liberal minister Don Chipp agreed to lead the new party. + +The party's broad aim was to achieve a balance of power in one or more parliaments and to exercise it responsibly in line with policies determined by membership. + +The first Australian Democrat parliamentarian was Robin Millhouse, the sole New LM member of the South Australian House of Assembly, who joined the Democrats in 1977. Millhouse held his seat (Mitcham) at the 1977 and 1979 state elections. In 1982, Millhouse resigned to take up a senior judicial appointment, and Heather Southcott won the by-election for the Democrats, but lost the seat to the Liberals later that year at the 1982 state election. Mitcham was the only single-member lower-house seat anywhere in Australia to be won by the Democrats. + +The first Democrat federal parliamentarian was Senator Janine Haines, who in 1977 was nominated by the South Australian Parliament to fill the casual vacancy caused by the resignation of Liberal Senator Steele Hall. Hall had been elected as a Liberal Movement senator, before rejoining the Liberal Party in 1976, and South Australian premier Don Dunstan nominated Haines on the basis that the Democrats was the successor party to the Liberal Movement. + +At the 1977 election, the Australian Democrats secured two seats in the Senate with the election of Colin Mason (NSW) and Don Chipp (VIC), though Haines lost her seat in South Australia. At the 1980 election, this increased to five seats with the election of Michael Macklin (QLD) and John Siddons (VIC) and the return of Janine Haines (SA). Thereafter they frequently held enough seats to give them the balance of power in the upper chamber. + +At a Melbourne media conference on 19 September 1980, in the midst of the 1980 election campaign, Chipp described his party's aim as to "keep the bastards honest"—the "bastards" being the major parties and/or politicians in general. This became a long-lived slogan for the Democrats. + +1986–1990: Janine Haines' leadership + +Don Chipp resigned from the Senate on 18 August 1986, being succeeded as party leader by Janine Haines and replaced as a senator for Victoria by Janet Powell. + +At the 1987 election following a double dissolution, the reduced quota of 7.7% necessary to win a seat assisted the election of three new senators. 6-year terms were won by Paul McLean (NSW) and incumbents Janine Haines (South Australia) and Janet Powell (Victoria). In South Australia, a second senator, John Coulter, was elected for a 3-year term, as were incumbent Michael Macklin (Queensland) and Jean Jenkins (Western Australia). + +1990 saw the voluntary departure from the Senate of Janine Haines (a step with which not all Democrats agreed) and the failure of her strategic goal of winning the House of Representatives seat of Kingston. The casual vacancy was filled by Meg Lees several months before the election of Cheryl Kernot in place of retired deputy leader Michael Macklin. The ambitious Kernot immediately contested the party's national parliamentary deputy leadership. Being unemployed at the time, she requested and obtained party funds to pay for her travel to address members in all seven divisions. In the event, Victorian Janet Powell was elected as leader and John Coulter was chosen as deputy leader. + +1990–1993: Janet Powell and John Coulter +Despite the loss of Haines and the WA Senate seat (through an inconsistent national preference agreement with the ALP), the 1990 federal election heralded something of a rebirth for the party, with a dramatic rise in primary vote. This was at the same time as an economic recession was building, and events such as the Gulf War in Kuwait were beginning to shepherd issues of globalisation and transnational trade on to national government agendas. + +The Australian Democrats had a long-standing policy to oppose war and so opposed Australia's support of, and participation in, the Gulf War. Whereas the House of Representatives was able to avoid any debate about the war and Australia's participation, the Democrats took full advantage of the opportunity to move for a debate in the Senate. + +Because of the party's pacifist-based opposition to the Gulf War, there was mass-media antipathy and negative publicity which some construed as poor media performance by Janet Powell, the party's standing having stalled at about 10%. Before 12 months of her leadership had passed, the South Australian and Queensland divisions were circulating the party's first-ever petition to criticise and oust the parliamentary leader. The explicit grounds related to Powell's alleged responsibility for poor AD ratings in Gallup and other media surveys of potential voting support. When this charge was deemed insufficient, interested party officers and senators reinforced it with negative media 'leaks' concerning her openly established relationship with Sid Spindler and exposure of administrative failings resulting in excessive overtime to a staff member. With National Executive blessing, the party room pre-empted the ballot by replacing the leader with deputy John Coulter. In the process, severe internal divisions were generated. One major collateral casualty was the party whip Paul McLean who resigned and quit the Senate in disgust at what he perceived as in-fighting between close friends. The casual NSW vacancy created by his resignation was filled by Karin Sowada. Powell duly left the party, along with many leading figures of the Victorian branch of the party, and unsuccessfully stood as an Independent candidate when her term expired. In later years, she campaigned for the Australian Greens. + +1993–1997: Cheryl Kernot + +The party's parliamentary influence was weakened in 1996 after the Howard government was elected, and a Labor senator, Mal Colston, resigned from the Labor Party. Since the Democrats now shared the parliamentary balance of power with two Independent senators, the Coalition government was able on occasion to pass legislation by negotiating with Colston and Brian Harradine. + +In October 1997, party leader Cheryl Kernot resigned, announcing that she would be joining the Australian Labor Party. (Five years later it was revealed that she had been in a sexual relationship with Labor deputy leader Gareth Evans). Kernot resigned from the Senate and was replaced by Andrew Bartlett, while deputy Meg Lees became the new party leader. + +1997–2004: Meg Lees, Natasha Stott Despoja and Andrew Bartlett +Under Lees' leadership, in the 1998 federal election, the Democrats' candidate John Schumann came within 2 per cent of taking Liberal Foreign Minister Alexander Downer's seat of Mayo in the Adelaide Hills under Australia's preferential voting system. The party's representation increased to nine senators, and they regained the balance of power, holding it until the Coalition gained a Senate majority at the 2004 election. + +Internal conflict and leadership tensions from 2000 to 2002, blamed on the party's support for the Government's Goods and Services Tax, was damaging to the Democrats. Opposed by the Labor Party, the Australian Greens and independent Senator Harradine, the tax required Democrat support to pass. In an election fought on tax, the Democrats publicly stated that they liked neither the Liberal's nor the Labor's tax packages, but pledged to work with whichever party was elected to make theirs better. They campaigned with the slogan "No Goods and Services Tax on Food". + +In 1999, after negotiations with Prime Minister Howard, Meg Lees, Andrew Murray and the party room senators agreed to support the A New Tax System legislation with exemptions from goods and services tax for most food and some medicines, as well as many environmental and social concessions. Five Australian Democrats senators voted in favour. However, two dissident senators on the party's left, Natasha Stott Despoja and Andrew Bartlett, voted against the GST. + +The decision to pass the GST was opposed by the majority of the Democrats' members, and in 2001 a leadership spill saw Lees replaced as leader by Stott Despoja after a very public and bitter leadership battle. Despite criticism of Stott Despoja's youth and lack of experience, the 2001 election saw the Democrats receive similar media coverage to the previous election. Despite the internal divisions, the Australian Democrats' election result in 2001 was quite good. However, it was not enough to prevent the loss of Vicki Bourne's Senate seat in NSW. + +The 2002 South Australian election was the last time an Australian Democrat would be elected to an Australian parliament. Sandra Kanck was re-elected to a second eight-year term from an upper house primary vote of 7.3 percent. + +Resulting tensions between Stott Despoja and Lees led to Meg Lees leaving the party in 2002, becoming an independent and forming the Australian Progressive Alliance. Stott Despoja stood down from the leadership following a loss of confidence by her party room colleagues. It led to a protracted leadership battle in 2002, which eventually led to the election of Senator Andrew Bartlett as leader. While the public fighting stopped, the public support for the party remained at record lows. + +On 6 December 2003, Bartlett stepped aside temporarily as leader of the party, after an incident in which he swore at Liberal Senator Jeannie Ferris on the floor of Parliament while intoxicated. The party issued a statement stating that deputy leader Lyn Allison would serve as the acting leader of the party. Bartlett apologised to the Democrats, Jeannie Ferris and the Australian public for his behaviour and assured all concerned that it would never happen again. On 29 January 2004, after seeking medical treatment, Bartlett returned to the Australian Democrats leadership, vowing to abstain from alcohol. + +Decline +Following internal conflict over the goods and services tax and resultant leadership changes, a dramatic decline occurred in the Democrats' membership and voting support in all states. Simultaneously, an increase was recorded in support for the Australian Greens who, by 2004, were supplanting the Democrats as a substantial third party. The trend was noted that year by political scientists Dean Jaensch et al. + +Support for the Australian Democrats fell significantly at the 2004 federal election in which they achieved only 2.4 per cent of the national vote. Nowhere was this more noticeable than in their key support base of suburban Adelaide in South Australia, where they received between 1 and 4 percent of the lower house vote; by comparison, they tallied between 7 and 31 per cent of the vote in 2001. No Democrat senators were elected, though four kept their seats due to being elected in 2001, thus their representation fell from eight senators to four. Three incumbent senators were defeated: Aden Ridgeway (NSW), Brian Greig (WA) and John Cherry (Qld). Following the loss, the customary post-election leadership ballot installed Allison as leader, with Bartlett as her deputy. From 1 July 2005 the Australian Democrats lost official parliamentary party status, being represented by only four senators while the governing Liberal-National Coalition gained a majority and potential control of the Senate—the first time this advantage had been enjoyed by any government since 1980. + +On 28 August 2006, the founder of the Australian Democrats, Don Chipp, died. Former prime minister Bob Hawke said: "... there is a coincidental timing almost between the passing of Don Chipp and what I think is the death throes of the Democrats." In November 2006, the Australian Democrats fared very poorly in the Victorian state election, receiving a Legislative Council vote tally of only 0.83%, less than half of the party's result in 2002 (1.79 per cent). + +The Democrats again had no success at the 2007 federal election, and lost all four of their remaining Senate seats. Two incumbent senators, Lyn Allison (Victoria) and Andrew Bartlett (Queensland), were defeated, their seats both reverting to major parties. Their two remaining colleagues, Andrew Murray (WA) and Natasha Stott Despoja (SA), retired. All four senators' terms expired on 30 June 2008—leaving the Australian Democrats with no federal representation for the first time since its founding in 1977. Later, in 2009, Jaensch suggested it was possible the Democrats could make a political comeback at the 2010 South Australian election, but this did not occur. + +State/territory losses +The Tasmanian division of the party was deregistered for having insufficient members in January 2006. + +At the 2006 South Australian election, the Australian Democrats were reduced to 1.7 per cent of the Legislative Council (upper house) vote. Their sole councillor up for re-election, Kate Reynolds, was defeated. In July 2006, Richard Pascoe, national and South Australian party president, resigned, citing slumping opinion polls and the poor result in the 2006 South Australian election as well as South Australian parliamentary leader Sandra Kanck's comments regarding the drug MDMA which he saw as damaging to the party. + +In the New South Wales state election of March 2007, the Australian Democrats lost their last remaining NSW Upper House representative, Arthur Chesterfield-Evans. The party fared poorly, gaining only 1.8 per cent of the Legislative Council vote. + +On 13 September 2007, the ACT Democrats (Australian Capital Territory Division of the party) was deregistered by the ACT Electoral Commissioner, being unable to demonstrate a minimum membership of 100 electors. + +These losses left Sandra Kanck, in South Australia, as the party's only parliamentarian. She retired in 2009 and was replaced by David Winderlich, making him (as of 2020) the last Democrat to sit in any Australian parliament. The Democrats lost all representation when Winderlich resigned from the party in October 2009. He sat the remainder of his term as an independent, and lost his seat at the 2010 South Australian election. + +Post-parliamentary decline +Following the loss of all Democrats MP's in both federal and state parliaments, the party continued to be riven by factionalism. In 2009 a dispute arose between two factions, the "Christian Centrists" loyal to former leader Meg Lees, and a faction comprising the party's more progressive members. The dispute arose when the Christian Centrist controlled national executive removed a website for party members from the internet, stating that its operation was a violation of the party constitution. In response, the progressive faction accused the national executive of being undemocratic and of acting contrary to the party constitution themselves. By 2012, this dispute had been superseded by another between members loyal to former Senator Brian Greig and members who were supporters of former South Australian MP Sandra Kanck. Brian Greig was elected the party's president, but resigned after less than a month due to frustration with the party's factionalism. + +Deregistration +On 16 April 2015, the Australian Electoral Commission deregistered the Australian Democrats as a political party for failure to demonstrate the requisite 500 members to maintain registration. However, the party did run candidates and remain registered for a period of time thereafter in the New South Wales Democrats and Queensland Democrat divisions. + +Renewed registration (2019–present) +In November 2018 there was a report that CountryMinded, a de-registered microparty, would merge with the Australian Democrats in a new bid to seek membership growth, electoral re-registration and financial support. In February 2019, application for registration was submitted to the AEC and was upheld on 7 April 2019, despite an objection from the Australian Democrats (Queensland Division). + +The party unsuccessfully contested the lower-house seat of Adelaide and a total of six Senate seats (two in each state of New South Wales, Victoria and South Australia) at the 2019 federal election. At the 2022 federal election one lower-house seat (Eden-Monaro) and three Senate seats were contested without success, polling fewer than 0.7% of first-preference votes. + +Overview +The party was founded on principles of honesty, tolerance, compassion and direct democracy through postal ballots of all members, so that "there should be no hierarchical structure ... by which a carefully engineered elite could make decisions for the members." From the outset, members' participation was fiercely protected in national and divisional constitutions prescribing internal elections, regular meeting protocols, annual conferences—and monthly journals for open discussion and balloting. Dispute resolution procedures were established, with final recourse to a party ombudsman and membership ballot. + +Policies determined by the unique participatory method promoted environmental awareness and sustainability, opposition to the primacy of economic rationalism (Australian neoliberalism), preventative approaches to human health and welfare, animal rights, rejection of nuclear technology and weapons. + +The Australian Democrats were the first representatives of green politics at the federal level in Australia. They "were in the vanguard of environmentalism in Australia. From the early 1980s they were unequivocally opposed to the building of the Franklin Dam in Tasmania and they opposed the mining and export of uranium and the development of nuclear power plants in Australia." In particular, leader Don Chipp, and Tasmanian state Democrat Norm Sanders, played crucial legislative roles in protecting the Franklin Dam. + +The party's centrist role made it subject to criticism from both the right and left of the political spectrum. In particular, Chipp's former conservative affiliation was frequently recalled by opponents on the left. This problem was to torment later leaders and strategists who, by 1991, were proclaiming "the electoral objective" as a higher priority than the rigorous participatory democracy espoused by the party's founders. + +Because of their numbers on the cross benches during the Hawke and Keating governments, the Democrats were sometimes regarded as exercising a balance of power—which attracted electoral support from a significant sector of the electorate which had been alienated by both Labor and Coalition policies and practices. + +Electoral results + +Federal parliamentary leaders + +Notes + +Parliamentarians + +Senators + +State and territory members + +Australian Capital Territory +1977–1986: Ivor Vivian, member of the House of Assembly +1977–1986: Gordon Walsh, member of the House of Assembly +2001–2004: Roslyn Dundas, member of the Legislative Assembly + +New South Wales +1981–1998: Elisabeth Kirkby, member of the Legislative Council +1988–1996: Richard Jones, member of the Legislative Council +1998–2007: Arthur Chesterfield-Evans, member of the Legislative Council + +South Australia +1977–1982: Robin Millhouse, member of the House of Assembly +1979–1985: Lance Milne, member of the Legislative Council +1982: Heather Southcott, member of the House of Assembly +1982–1993, 1997–2006: Ian Gilfillan, member of the Legislative Council +1985–2003: Mike Elliott, member of the Legislative Council +1993–2009: Sandra Kanck, member of the Legislative Council +2003–2006: Kate Reynolds, member of the Legislative Council +2009: David Winderlich, member of the Legislative Council + +Tasmania +1980–1982: Norm Sanders, member of the House of Assembly + +Western Australia +1997–2001: Helen Hodgson, member of the Legislative Council +1997–2001: Norm Kelly, member of the Legislative Council + +See also +Social liberalism +Liberalism worldwide +List of liberal parties +Liberal democracy +Timeline of (small-l) liberal parties in Australia + +Notes + +References + +Further reading +Bennett D, Discord in the Democrats PWHCE article, Melbourne 2002 +Beyond Our Expectations—Proceedings of the Australian Democrats First National Conference, Canberra, 16–17 February 1980.

Canberra, the capital city of Australia, is located in this territory. It is located in southeastern Australian mainland as an enclave completely within the state of New South Wales. Founded after Federation as the seat of government for the new nation, the territory hosts the headquarters of all important institutions of the Australian Government. + +On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the Seat of Government Act 1908 was passed in 1908 which specified a capital in the Yass-Canberra region. The territory was transferred to the federal government by New South Wales in 1911, two years prior to the capital city being founded and formally named as Canberra in 1913. + +While the overwhelming majority of the population reside in the city of Canberra in the ACT's north-east, the territory also includes some towns such as Williamsdale, Oaks Estate, Uriarra, Tharwa and Hall. The ACT also includes the Namadgi National Park, which comprises the majority of land area of the territory. Despite a common misconception, the Jervis Bay Territory is not part of the ACT, although the laws of the Australian Capital Territory apply as if Jervis Bay did form part of the ACT. The territory has a relatively dry, continental climate, experiencing warm to hot summers and cool to cold winters. + +The Australian Capital Territory is home to many important institutions of the federal government, national monuments and museums. These include the Parliament of Australia, the High Court of Australia, the Australian Defence Force Academy and the Australian War Memorial. It also hosts the majority of foreign embassies in Australia, as well as regional headquarters of many international organisations, not-for-profit groups, lobbying groups and professional associations. Several major universities also have campuses in the ACT, including the Australian National University, the University of Canberra, the University of New South Wales, Charles Sturt University and the Australian Catholic University. + +A locally elected legislative assembly has governed the territory since 1988. However, the Commonwealth maintains authority over the territory and may overturn local laws. It still maintains control over the area known as the Parliamentary Triangle through the National Capital Authority. Residents of the territory elect three members of the House of Representatives and two senators. + +With 453,324 residents, the Australian Capital Territory is the second smallest mainland state or territory by population. At the , the median weekly income for people in the territory aged over 15 was $998, significantly higher than the national average of $662. The average level of degree qualification in the ACT is also higher than the national average. Within the ACT, 37.1% of the population hold a bachelor's degree level or above education compared to the national figure of 20%. + +History + +Indigenous inhabitants +Aboriginal Australian peoples have long inhabited the area. Evidence indicates habitation dating back at least 25,000 years, and it is possible that the area was inhabited for considerably longer, with evidence of an Aboriginal presence at Lake Mungo dating back around 40,000–62,000 years. The principal group occupying the region were the Ngunnawal people, with the Ngarigo and Walgalu living immediately to the south, the Wandadian to the east, the Gandangara to the north and the Wiradjuri to the north-west. + +European colonisation +Following European settlement, the growth of the new colony of New South Wales led to an increasing demand for arable land. Governor Lachlan Macquarie supported expeditions to open up new lands to the south of Sydney. The 1820s saw further exploration in the Canberra area associated with the construction of a road from Sydney to the Goulburn plains. While working on the project, Charles Throsby learned of a nearby lake and river from the local Indigenous peoples and he accordingly sent Wild to lead a small party to investigate the site. The search was unsuccessful, but they did discover the Yass River, and it is surmised that they would have set foot on part of the future territory. + +A second expedition was mounted shortly thereafter, and they became the first Europeans to camp at the Molonglo (Ngambri) and Queanbeyan (Jullergung) Rivers. However, they failed to find the Murrumbidgee River. The issue of the Murrumbidgee was solved in 1821 when Throsby mounted a third expedition and successfully reached the watercourse, on the way providing the first detailed account of the land where the Australian Capital Territory now resides. The last expedition in the region before settlement was undertaken by Allan Cunningham in 1824. He reported that the region was suitable for grazing and the settlement of the Limestone Plains followed immediately thereafter. + +Early settlement + +The first land grant in the region was made to Joshua John Moore in 1823, and European settlement in the area began in 1824 with the construction of a homestead by his stockmen on what is now the Acton Peninsula. Moore formally purchased the site in 1826 and named the property Canberry or Canberra. + +A significant influx of population and economic activity occurred around the 1850s goldrushes. The goldrushes prompted the establishment of communication between Sydney and the region by way of the Cobb & Co coaches, which transported mail and passengers. The first post offices opened in Ginninderra in 1859 and at Lanyon in 1860. + +During colonial times, the European communities of Ginninderra, Molonglo and Tuggeranong settled and farmed the surrounding land. The region was also called the Queanbeyan-Yass district, after the two largest towns in the area. The villages of Ginninderra and Tharwa developed to service the local agrarian communities. + +During the first 20 years of settlement, there was only limited contact between the settlers and Aboriginal people. Over the succeeding years, the Ngunnawal and other local indigenous people effectively ceased to exist as cohesive and independent communities adhering to their traditional ways of life. Those who had not succumbed to disease and other predations either dispersed to the local settlements or were relocated to more distant Aboriginal reserves set up by the New South Wales government in the latter part of the 19th century. + +Creation of the territory + +In 1898, a referendum on a proposed Constitution was held in four of the colonies – New South Wales, Victoria, South Australia and Tasmania. Although the referendum achieved a majority in all four colonies, the New South Wales referendum failed to gain the minimum number of votes needed for the bill to pass. Following this result, a meeting of the four Premiers in 1898 heard from George Reid, the Premier of New South Wales, who argued that locating the future capital in New South Wales would be sufficient to ensure the passage of the Bill. The 1899 referendum on this revised bill was successful and passed with sufficient numbers. Section 125 of the Australian Constitution thus provided that, following Federation in 1901, land would be ceded freely to the new Federal Government. + +This, however, left open the question of where to locate the capital. In 1906 and after significant deliberations, New South Wales agreed to cede sufficient land on the condition that it was in the Yass-Canberra region, this site being closer to Sydney. Initially, Dalgety, New South Wales remained at the forefront, but Yass-Canberra prevailed after voting by federal representatives. The Seat of Government Act 1908 was passed in 1908, which repealed the 1904 Act and specified a capital in the Yass-Canberra region. Government surveyor Charles Scrivener was deployed to the region in the same year to map out a specific site and, after an extensive search, settled upon the present location, basing the borders primarily on the need to secure a stable water supply for the planned capital. + +The Australian Capital Territory was transferred to the Commonwealth by New South Wales on 1 January 1911, two years before the naming of Canberra as the national capital on 20 March 1913. + +The Commonwealth gained control of all land within the borders of the new territory but ownership only of NSW Crown land, with significant parcels of extant freehold remaining in the hands of their pre-existing owners. Much of this was acquired during World War One, though a few titles were not transferred until the late 20th Century. + +Land within the territory is granted under a leasehold system, with 99-year residential leases sold to buyers as new suburbs are planned, surveyed, and developed. The current policy is for these leases to be extended for another 99-year period on expiry, subject to payment of an administrative fee. + +Development throughout 20th century + +In 1911, an international competition to design the future capital was held; it was won by the Chicago architect Walter Burley Griffin in 1912. The official naming of Canberra occurred on 12 March 1913 and construction began immediately. + +After Griffin's departure following difficulty in implementing his project, the Federal Capital Advisory Committee was established in 1920 to advise the government of the construction efforts. The committee had limited success meeting its goals. However, the chairman, John Sulman, was instrumental in applying the ideas of the garden city movement to Griffin's plan. The committee was replaced in 1925 by the Federal Capital Commission. + +In 1930, the ACT Advisory Council was established to advise the minister for territories on the community's concerns. In 1934, the Supreme Court of the Australian Capital Territory was established. + +From 1938 to 1957, the National Capital Planning and Development Committee continued to plan the further expansion of Canberra. However, it did not have executive power, and decisions were made on the development of Canberra without consulting the committee. During this time, Prime Minister Robert Menzies regarded the state of the national capital as an embarrassment. + +After World War II, there was a shortage of housing and office space in Canberra. A Senate Select Committee hearing was held in 1954 to address its development requirements. This Committee recommended the creation of a single planning body with executive power. Consequently, the National Capital Planning and Development Committee was replaced by the National Capital Development Commission in 1957. The National Capital Development Commission ended four decades of disputes over the shape and design of Lake Burley Griffin and construction was completed in 1964 after four years of work. The completion of the centrepiece of Griffin's design finally laid the platform for the development of Griffin's Parliamentary Triangle. + +Self-government +In 1978, an advisory referendum was held to determine the views of ACT citizens about whether there should be self-government. Just under 64 percent of voters rejected devolved government options, in favour of the status quo. Nevertheless, in 1988, the new minister for the Australian Capital Territory Gary Punch received a report recommending the abolition of the National Capital Development Commission and the formation of a locally elected government. Punch recommended that the Hawke government accept the report's recommendations and subsequently Clyde Holding introduced legislation to grant self-government to the territory in October 1988. + +The enactment on 6 December 1988 of the Australian Capital Territory (Self-Government) Act 1988 established the framework for self-government. The first election for the 17-member Australian Capital Territory Legislative Assembly was held on 4 March 1989. + +The initial years of self-government were difficult and unstable. A majority of ACT residents had opposed self-government and had it imposed upon them by the federal parliament. At the first election, 4 of the 17 seats were won by anti-self-government single-issue parties due to a protest vote by disgruntled Canberrans and a total of 8 were won by minor parties and independents. + +In 1992, Labor won eight seats and the minor parties and independents won only three. Stability increased, and in 1995, Kate Carnell became the first elected Liberal chief minister. In 1998, Carnell became the first chief minister to be re-elected. + +Geography + +The Australian Capital Territory is the smallest mainland territory (aside from the Jervis Bay Territory) and covers a total land area of , slightly smaller than Luxembourg. + +It is bounded by the Bombala railway line in the east, the watershed of Naas Creek in the south, the watershed of the Cotter River in the west and the watershed of the Molonglo River in the north-east. These boundaries were set to give the ACT an adequate water supply. The ACT extends about north-south between 35.124°S and 35.921°S, and west-east between 148.763°E and 149.399°E. The city area of Canberra occupies the north-eastern corner of this area. + +The Australian Capital Territory includes the city of Canberra and some towns such as Williamsdale, Oaks Estate, Uriarra Village, Tharwa and Hall. The Australian Capital Territory also contains agricultural land (sheep, dairy cattle, vineyards and small amounts of crops) and a large area of national park (Namadgi National Park), much of it mountainous and forested. + +Tidbinbilla is a locality to the south-west of Canberra that features the Tidbinbilla Nature Reserve and the Canberra Deep Space Communication Complex, operated by the United States' NASA as part of its Deep Space Network. The Southern Tablelands Temperate Grassland straddles the state. + +The territory includes a large range of mountains, rivers and creeks, largely contained within the Namadgi National Park. These include the Naas and Murrumbidgee Rivers. + +In September 2022, it was announced that the border between NSW and the ACT would change for the first time since it was created in 1911. ACT chief minister Andrew Barr said NSW premier Dominic Perrottet had agreed to a proposed border change of in the Ginninderra watershed. + +Climate + +The territory has a relatively dry, continental climate, experiencing warm to hot summers and cool to cold winters. Under the Köppen-Geiger classification, the territory has an oceanic climate (Cfb). + +January is the hottest month with an average high of 27.7°C. July is the coldest month when the average high drops to . The highest maximum temperature recorded in the territory was 44.0°C on 4 January 2020. The lowest minimum temperature was −10.0°C on 11 July 1971. + +Rainfall varies significantly across the territory. Much higher rainfall occurs in the mountains to the west of Canberra compared to the east. The mountains act as a barrier during winter with the city receiving less rainfall. Average annual rainfall in the territory is 629mm and there is an average of 108 rain days annually. The wettest month is October, with an average rainfall of 65.3mm, and the driest month is June, with an average of 39.6mm. + +Frost is common in the winter months. Snow is rare in Canberra's city centre, but the surrounding areas get annual snowfall through winter and often the snow-capped mountains can be seen from the city. The last significant snowfall in the city centre was in 1968. + +Smoke haze became synonymous with the 2019/2020 Australian summer. On 1 January 2020 Canberra had the worst air quality of any major city in the world, with an AQI of 7700 (USAQI 949). + +Geology + +Notable geological formations in the Australian Capital Territory include the Canberra Formation, the Pittman Formation, Black Mountain Sandstone and State Circle Shale. + +In the 1840s fossils of brachiopods and trilobites from the Silurian period were discovered at Woolshed Creek near Duntroon. At the time, these were the oldest fossils discovered in Australia, though this record has now been far surpassed. Other specific geological places of interest include the State Circle cutting and the Deakin anticline. + +The oldest rocks in the ACT date from the Ordovician around 480 million years ago. During this period the region along with most of Eastern Australia was part of the ocean floor; formations from this period include the Black Mountain Sandstone formation and the Pittman Formation consisting largely of quartz-rich sandstone, siltstone and shale. These formations became exposed when the ocean floor was raised by a major volcanic activity in the Devonian forming much of the east coast of Australia. + +Flora and fauna + +The environments range from alpine area on the higher mountains, to sclerophyll forest and to woodland. Much of the ACT has been cleared for grazing and is also burnt off by bushfires several times per century. The kinds of plants can be grouped into vascular plants, that include gymnosperms, flowering plants, and ferns, as well as bryophytes, lichens, fungi and freshwater algae. Four flowering plants are endemic to the ACT. Several lichens are unique to the territory. Most plants in the ACT are characteristic of the Flora of Australia and include well known plants such as Grevillea, Eucalyptus trees and kangaroo grass. + +The native forest in the Australian Capital Territory was almost wholly eucalypt species and provided a resource for fuel and domestic purposes. By the early 1960s, logging had depleted the eucalypt, and concern about water quality led to the forests being closed. Interest in forestry began in 1915 with trials of a number of species including Pinus radiata on the slopes of Mount Stromlo. Since then, plantations have been expanded, with the benefit of reducing erosion in the Cotter catchment, and the forests are also popular recreation areas. + +The fauna of the territory includes representatives from most major Australian animal groups. This includes kangaroos, wallabies, koalas, platypus, echidna, emu, kookaburras and dragon lizards. + +Government and politics + +Territory government + +Unlike the States of Australia which have their own constitutions, territories like the ACT are governed under a Commonwealth statutefor the ACT, the Australian Capital Territory (Self-Government) Act 1988. The Self-Government Act constitutes a democratic government for the Territory consisting of a popularly elected Legislative Assembly which elects a Chief Minister from among its membership who, in turn, appoints an Executive consisting of a number of Ministers. + +The executive power of the Territory rests with the ACT Government, led by the Executive. The Executive is chaired by the Chief Minister (currently the Labor Party's Andrew Barr) and consists of Ministers appointed by them. The Executive are supported by the ACT Public Service, which is arranged into directorates, and a number of public authorities. The Chief Minister is the equivalent of a State Premier and sits on the National Cabinet. Unlike the States and the Northern Territory, there is no vice-regal representative who chairs the Executive. The Chief Minister performs many of the roles that a state governor normally holds in the context of a state; however, the Speaker of the Legislative Assembly gazettes the laws and summons meetings of the Assembly. + +The legislative power of the Territory is vested in the unicameral Legislative Assembly. The Assembly consists of 25 members who are elected from five electorates using the Hare-Clark single transferable voting system. The Assembly is presided over by the Speaker (currently the Labor Party's Joy Burch). The Assembly has almost all of the same powers as the state parliaments, the power to "make laws for the peace, order, and good government of the Territory", with limited exceptions relating to the Territory's unique relationship with the Commonwealth. The Hare-Clark voting system was adopted after a referendum in 1992 and was entrenched by another referendum in 1995. The electoral system cannot be changed except by a two-thirds majority in the Assembly or a majority vote of support at a public referendum. + +There is no level of local government below the Territory government as in the States and the functions associated with local government are carried out principally by the Transport Canberra and City Services Directorate. There is an indigenous voice to the ACT Government, called the Aboriginal and Torres Strait Islander Elected Body. + +Despite the wide powers of the Territory government, the federal government continues to have power over the Territory. This includes an unused power to dissolve the Assembly and appoint a caretaker government in extraordinary circumstances. The federal and territory governments share some officers, such as the Ombudsman. The federal parliament also retains the power to make any law for the Territory under section 122 of the Constitution and an exclusive power to legislate for the "seat of government". Territory laws which conflict with federal law are inoperable to the extent of the inconsistency. Land in the Territory that is designated to be "National Land" under federal law remains under the control of the federal government, usually represented by the National Capital Authority. The federal parliament can disallow laws enacted by the Assembly by a joint resolution of both houses of Parliament, a power which replaced a federal executive veto in 2011. + +Judiciary and policing + +The judicial power of the Territory is exercised by the territory courts. These courts are the Supreme Court of the Australian Capital Territory, the Magistrates Court of the Australian Capital Territory and the ACT Civil and Administrative Tribunal. It is unique in that the territory does not have an intermediary court like other mainland states and territories; there is only the superior court and a court of summary jurisdiction. From 2001, appeals from the Supreme Court are heard by a panel of Supreme Court judges sitting as the Court of Appeal. The current Chief Justice is Lucy McCallum and the current Chief Magistrate is Lorraine Walker. + +The Federal Court has concurrent jurisdiction over civil matters arising under Territory law, a fact which has become increasingly important to the practice of defamation law across Australia. + +Policing services are provided by the ACT Policing unit of the Australian Federal Police under agreements between the territory government, the federal government, and the police force. Canberra had the lowest rate of crime of any capital city in Australia . + +Federal representation +In Australia's Federal Parliament, the ACT is represented by five federal members: three members of the House of Representatives represent the Division of Bean, the Division of Canberra and the Division of Fenner, and it is one of only two territories to be represented in the Senate, with two Senators (the other being the Northern Territory). The Member for Bean and the ACT Senators also represent the constituents of Norfolk Island. The Member for Fenner and the ACT Senators also represent the constituents of the Jervis Bay Territory. + +Jervis Bay Territory + +In 1915, the Jervis Bay Territory Acceptance Act 1915 created the Jervis Bay Territory as an annex to the Federal Capital Territory. While the Act's use of the language of "annexed" is sometimes interpreted as implying that the Jervis Bay Territory was to form part of the Federal Capital Territory, the accepted legal position is that it has been a legally distinct territory from its creation despite being subject to ACT law and, prior to ACT self-government in 1988, being administratively treated as part of the ACT. + +In 1988, when the ACT gained self-government, Jervis Bay was formally pronounced as a separate territory administered by the Commonwealth known as the Jervis Bay Territory. However, the laws of the ACT continue to apply to the Jervis Bay Territory. Magistrates from the ACT regularly travel to the Jervis Bay Territory to conduct court. + +Another occasional misconception is that the ACT retains a small area of territory on the coast on the Beecroft Peninsula, consisting of a strip of coastline around the northern headland of Jervis Bay. While the land is owned by the Commonwealth Government, that area itself is still considered to be under the jurisdiction of New South Wales government, not a separate territory nor a part of the ACT. + +Demographics + +The Australian Bureau of Statistics estimates that the population of the territory was 453,324 on 31 December 2021, with an annual growth in 2021 of 0.4%. A 2019 projection estimated the population would reach to approximately 700,000 by 2058. + +The overwhelming majority of the population reside in the city of Canberra. + +At the , the median weekly income for people in the territory aged over 15 was $998 while the national average was $662. + +The average level of degree qualification in the ACT is higher than the national average. Within the ACT, 37.1% of the population hold a bachelor's degree level or above education compared to the national figure of 20%. + +City and towns + +The Australian Capital Territory consists of the city of Canberra and some towns including Williamsdale, Oaks Estate, Uriarra, Tharwa and Hall. + +The urban areas of the Australian Capital Territory are organised into a hierarchy of districts, town centres, group centres, local suburbs as well as other industrial areas and villages. There are seven districts (with an eighth currently under construction), each of which is divided into smaller suburbs, and most of which have a town centre which is the focus of commercial and social activities. The districts were settled in the following chronological order: +North Canberra: mostly settled in the 1920s and '30s, with expansion up to the 1960s, now 14 suburbs; +South Canberra: settled from the 1920s to '60s, 13 suburbs; +Woden Valley: first settled in 1963, 12 suburbs; +Belconnen: first settled in 1967, 25 suburbs; +Weston Creek: settled in 1969, 8 suburbs; +Tuggeranong: settled in 1974, 19 suburbs; +Gungahlin: settled in the early 1990s, 18 suburbs although only 15 are developed or under development; +Molonglo Valley: first suburbs currently under construction. + +The North and South Canberra districts are substantially based on Walter Burley Griffin's designs. In 1967, the then National Capital Development Commission adopted the "Y Plan" which laid out future urban development in the Australian Capital Territory a series of central shopping and commercial area known as the 'town centres' linked by freeways, the layout of which roughly resembled the shape of the letter Y, with Tuggeranong at the base of the Y and Belconnen and Gungahlin located at the ends of the arms of the Y. + +Ancestry and immigration + +At the , the most commonly nominated ancestries were: + +The showed that 32.5% of the ACT's inhabitants were born overseas. Of inhabitants born outside of Australia, the most prevalent countries of birth were India, England, China, Nepal and New Zealand. + +2.0% of the population, or 8,949 people, identified as Indigenous Australians (Aboriginal Australians and Torres Strait Islanders) in 2021. + +Language +At the , 71.3% of people spoke only English at home. The other languages most commonly spoken at home were Mandarin (3.2%), Nepali (1.3%), Vietnamese (1.1%), Punjabi (1.1%), Hindi (1.0%). + +Religion +The most common responses in the for religion in the territory were No Religion (43.5%), Catholic (19.3%), Anglican (8.2%), Not stated (5.2%) and Hinduism (4.5%). + +Culture + +Education + +Almost all educational institutions in the Australian Capital Territory are located within Canberra. The ACT public education system schooling is normally split up into Pre-School, Primary School (K-6), High School (7–10) and College (11–12) followed by studies at University or Institute of Technology. Many private high schools include years 11 and 12 and are referred to as colleges. Children are required to attend school until they turn 17 under the ACT Government's "Learn or Earn" policy. + +In February 2004 there were 140 public and non-governmental schools in ACT; 96 were operated by the Government and 44 are non-Government. In 2005, there were 60,275 students in the ACT school system. 59.3% of the students were enrolled in government schools with the remaining 40.7% in non-government schools. There were 30,995 students in primary school, 19,211 in high school, 9,429 in college and a further 340 in special schools. + +As of May 2004, 30% of people in the ACT aged 15–64 had a level of educational attainment equal to at least a bachelor's degree, significantly higher than the national average of 19%. The two main tertiary institutions are the Australian National University (ANU) in Acton and the University of Canberra (UC) in Bruce. There are also two religious university campuses in Canberra: Signadou is a campus of the Australian Catholic University and St Mark's Theological College is a campus of Charles Sturt University. Tertiary level vocational education is also available through the multi-campus Canberra Institute of Technology (CIT). + +The Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC) are in the suburb of Campbell in Canberra's inner northeast. ADFA teaches military undergraduates and postgraduates and is officially a campus of the University of New South Wales while Duntroon provides Australian Army Officer training. + +The Academy of Interactive Entertainment (AIE) offers courses in computer game development and 3D animation. + +Sport + +The Australian Capital Territory is home to a number of major professional sports league franchise teams including the ACT Brumbies (Rugby Union), Canberra United (Soccer), Canberra Raiders (Rugby League) and the Canberra Capitals (Basketball). + +The Prime Minister's XI (Cricket), started by Robert Menzies in the 1950s and revived by Bob Hawke in 1984, has been played every year at Manuka Oval against an overseas touring team. + +The Greater Western Sydney Giants (Football) play three regular season matches a year and one pre-season match in Canberra at Manuka Oval. + +Arts and entertainment + +The territory is home to many national monuments and institutions such as the Australian War Memorial, the National Gallery of Australia, the National Portrait Gallery, the National Library, the National Archives, the Australian Academy of Science, the National Film and Sound Archive and the National Museum. Many Commonwealth government buildings in the Australian Capital Territory are open to the public, including Parliament House, the High Court and the Royal Australian Mint. + +Lake Burley Griffin is the site of the Captain James Cook Memorial and the National Carillon. Other sites of interest include the Telstra Tower, the Australian National Botanic Gardens, the National Zoo and Aquarium, the National Dinosaur Museum and Questacon – the National Science and Technology Centre. + +The Canberra Museum and Gallery in the city is a repository of local history and art, housing a permanent collection and visiting exhibitions. Several historic homes are open to the public: Lanyon and Tuggeranong Homesteads in the Tuggeranong Valley, Mugga-Mugga in Symonston, and Blundells' Cottage in Parkes all display the lifestyle of the early European settlers. Calthorpes' House in Red Hill is a well-preserved example of a 1920s house from Canberra's very early days. + +The Australian Capital Territory has many venues for live music and theatre: the Canberra Theatre and Playhouse which hosts many major concerts and productions; and Llewellyn Hall (within the ANU School of Music), a world-class concert hall are two of the most notable. The Albert Hall was Canberra's first performing arts venue, opened in 1928. It was the original performance venue for theatre groups such as the Canberra Repertory Society. + +There are numerous bars and nightclubs which also offer live entertainment, particularly concentrated in the areas of Dickson, Kingston and the city. Most town centres have facilities for a community theatre and a cinema, and they all have a library. Popular cultural events include the National Folk Festival, the Royal Canberra Show, the Summernats car festival, Enlighten festival and the National Multicultural Festival in February. + +Media +The Australian Capital Territory have a daily newspaper, The Canberra Times, which was established in 1926. There are also several free weekly publications, including news magazines City News and Canberra Weekly. + +Major daily newspapers such as The Daily Telegraph and The Sydney Morning Herald from Sydney, The Age and The Herald Sun from Melbourne as well as national publications The Australian and The Australian Financial Review are also available for purchase via retail outlets or via home delivery in the Australian Capital Territory. + +There are a number of AM and FM stations broadcasting throughout the ACT (AM/FM Listing). The main commercial operators are the Capital Radio Network (2CA and 2CC), and Austereo/ARN (104.7 and Mix 106.3). There are also several community operated stations as well as the local and national stations of the Australian Broadcasting Corporation. + +A DAB+ digital radio trial is also in operation, it simulcasts some of the AM/FM stations, and also provides several digital only stations (DAB+ Trial Listing). + +Five free-to-air television stations service the territory: + +ABC Canberra (ABC) +SBS New South Wales (SBS) +WIN Television Southern NSW & ACT (WIN) – Nine Network affiliate +Prime7 Southern NSW & ACT (CBN) – A Seven Network owned & operated station +Southern Cross 10 Southern NSW & ACT (CTC) – Network 10 affiliate + +Each station broadcasts a primary channel and several multichannels. + +Pay television services are available from Foxtel (via satellite) and telecommunications company TransACT (via cable). + +Infrastructure + +Health + +The Australian Capital Territory has two large public hospitals both located in Canberra: the approximately 600-bed Canberra Hospital in Garran and the 174-bed Calvary Public Hospital in Bruce. Both are teaching institutions. The largest private hospital is the Calvary John James Hospital in Deakin. Calvary Private Hospital in Bruce and Healthscope's National Capital Private Hospital in Garran are also major healthcare providers. + +The Australian Capital Territory has 10 aged care facilities. ACT's hospitals receive emergency cases from throughout southern New South Wales, and ACT Ambulance Service is one of four operational agencies of the ACT Emergency Services Authority. NETS provides a dedicated ambulance service for inter-hospital transport of sick newborns within the ACT and into surrounding New South Wales. + +Transport + +The automobile is by far the dominant form of transport in the Australian Capital Territory. The city is laid out so that arterial roads connecting inhabited clusters run through undeveloped areas of open land or forest, which results in a low population density; this also means that idle land is available for the development of future transport corridors if necessary without the need to build tunnels or acquire developed residential land. In contrast, other capital cities in Australia have substantially less green space. + +Australian Capital Territory's localities are generally connected by parkways—limited access dual carriageway roads with speed limits generally set at a maximum of . An example is the Tuggeranong Parkway which links Canberra's CBD and Tuggeranong, and bypasses Weston Creek. In most districts, discrete residential suburbs are bounded by main arterial roads with only a few residential linking in, to deter non-local traffic from cutting through areas of housing. + +ACTION, the government-operated bus service, provides public transport throughout the Australian Capital Territory. CDC Canberra provides bus services between the Australian Capital Territory and nearby areas of New South Wales (Murrumbateman and Yass) and as Qcity Transit (Queanbeyan). A light rail line that opened in April 2019 links the CBD with the northern district of Gungahlin. At the 2016 census, 7.1% of the journeys to work involved public transport while 4.5% were on foot. + +There are two local taxi companies. Aerial Capital Group enjoyed monopoly status until the arrival of Cabxpress in 2007. In October 2015, the ACT Government passed legislation to regulate ride sharing, allowing ride share services including Uber to operate legally in the Australian Capital Territory. The ACT Government was the first jurisdiction in Australia to enact legislation to regulate the service. + +An interstate NSW TrainLink railway service connects Canberra to Sydney. Canberra's railway station is in the inner south suburb of Kingston. Train services to Melbourne are provided by way of a NSW TrainLink bus service which connects with a rail service between Sydney and Melbourne in Yass, about a one-hour drive from Canberra. + +Canberra is about three hours by road from Sydney on the Federal Highway (National Highway 23), which connects with the Hume Highway (National Highway 31) near Goulburn, and seven hours by road from Melbourne on the Barton Highway (National Highway 25), which joins the Hume Highway at Yass. It is a two-hour drive on the Monaro Highway (National Highway 23) to the ski fields of the Snowy Mountains and the Kosciuszko National Park. Batemans Bay, a popular holiday spot on the New South Wales coast, is also two hours away via the Kings Highway. + +Canberra Airport provides direct domestic services to Sydney, Melbourne, Brisbane, Adelaide, Gold Coast, Hobart and Perth, with connections to other domestic centres. There are also direct flights to regional cities: Dubbo and Newcastle in New South Wales. Regular direct international flights operate to Singapore and Doha from the airport daily, but both with a stopover in Sydney before Canberra. Canberra Airport is, as of September 2013, designated by the Australian Government Department of Infrastructure and Regional Development as a restricted use designated international airport. Until 2003, the civilian airport shared runways with RAAF Base Fairbairn. In June of that year, the Air Force base was decommissioned and from that time the airport was fully under civilian control. + +Utilities + +The government-owned Icon Water, formerly ACTEW, manages the territory's water and sewerage infrastructure. ActewAGL is a joint venture between Icon and AGL, and is the retail provider of Australian Capital Territory's utility services including water, natural gas, electricity, and also some telecommunications services via a subsidiary TransACT. + +Australian Capital Territory's water is stored in four reservoirs, the Corin, Bendora and Cotter dams on the Cotter River and the Googong Dam on the Queanbeyan River. Although the Googong Dam is located in New South Wales, it is managed by the ACT government. Icon Water owns Australian Capital Territory's two wastewater treatment plants, located at Fyshwick and on the lower reaches of the Molonglo River. + +Electricity for the Australian Capital Territory mainly comes from the national power grid through substations at Holt and Fyshwick (via Queanbeyan). Power was first supplied from a thermal plant built in 1913, near the Molonglo River, but this was finally closed in 1957. The ACT has four solar farms, which were opened between 2014 and 2017: Royalla (rated output of 20 megawatts, 2014), Mount Majura (2.3 MW, 2016), Mugga Lane (13 MW, 2017) and Williamsdale (11 MW, 2017). In addition numerous houses in Canberra have photovoltaic panels and/or solar hot water systems. In 2015/16, rooftop solar systems supported by the ACT government's feed-in tariff had a capacity of 26.3 megawatts, producing 34,910 MWh. In the same year, retailer-supported schemes had a capacity of 25.2 megawatts and exported 28,815 MWh to the grid (power consumed locally was not recorded). + +The ACT has the highest rate with internet access at home (94 per cent of households in 2014–15). + +Economy + +The economic activity of the Australian Capital Territory is heavily concentrated around the city of Canberra. + +A stable housing market, steady employment and rapid population growth in the 21st century have led to economic prosperity and, in 2011, CommSec ranked the ACT as the second best performing economic region in the country. This trend continued into 2016, when the territory was ranked the third best performing out of all of Australia's states and territories. + +In 2017–18, the ACT had the fastest rate of growth in the nation due to a rapid growth in population, a strongly performing higher education sector as well as a significant housing and infrastructure investment. + +Higher education is the territory's largest export industry. The ACT is home to a significant number of universities and higher education providers. The other major services exports of the ACT in 2017-18 were government services and personal travel. The major goods exports of the territory in 2017-18 were gold coin, legal tender coin, metal structures and fish, though these represent a small proportion of the economy compared to services exports. + +The economy of the ACT is largely dependent on the public sector with 30% of the jobs in the territory being in the public sector. Decisions by the federal government regarding the public service can have a significant impact on the territory's economy. + +The ACT's gross state product in 2017-18 was $39.8 billion which represented 2.2% of the overall gross domestic product of Australia. In 2017-18 the ACT economy grew by 4.0 per cent, the highest growth rate of any jurisdiction in Australia. This brought real economic growth over the three years to June 2018 to 12 per cent. + +See also + +Community Based Corrections +Human Rights Act 2004 +Index of Australia-related articles +Jervis Bay Territory +Revenue stamps of the Australian Capital Territory + +Notes + +References + +Bibliography + +External links + +Government of the Australian Capital Territory +Legislative Assembly of the Australian Capital Territory +Supreme Court of the Australian Capital Territory +Statistical Subdivisions of the Australian Capital Territory +List of public art in Australian Capital Territory + + +Capital districts and territories +1911 establishments in Australia +Enclaves and exclaves +States and territories established in 1911 +Aotus (the name is derived from the Ancient Greek words for "earless" in both cases: the monkey is missing external ears, and the pea is missing earlike bracteoles) may refer to: + Aotus (plant), one of the plant genera commonly known as golden peas in the family Fabaceae (bean family) + Aotus (monkey), the genus of night monkeys in the family Aotidae + AOTUS, the acronym for the Archivist of the United States +Ally McBeal is an American legal comedy drama television series, originally aired on Fox from September 8, 1997, to May 20, 2002. Created by David E. Kelley, the series stars Calista Flockhart in the title role as a lawyer working in the Boston law firm Cage and Fish, with other lawyers whose lives and loves are eccentric, humorous, and dramatic. The series received critical acclaim in its early seasons, winning the Golden Globe Award for Best Television Series – Musical or Comedy in 1998 and 1999, and also winning the Emmy Award for Outstanding Comedy Series in 1999. As of August 2022, a revival is in development at ABC. + +Overview +The series, set in the fictional Boston law firm Cage & Fish, begins with main character Allison Marie "Ally" McBeal joining the firm co-owned by her law school classmate Richard Fish (Greg Germann) after leaving her previous job due to sexual harassment. On her first day, Ally is horrified to find that she will be working alongside her ex-boyfriend Billy Thomas (Gil Bellows)—whom she has never gotten over. To make things worse, Billy is now married to fellow lawyer Georgia (Courtney Thorne-Smith), who later joins Cage and Fish. The triangle among the three forms the basis for the main plot for the show's first three seasons. + +Although ostensibly a legal drama, the main focus of the series was the romantic and personal lives of the main characters, often using legal proceedings as plot devices to contrast or reinforce a character's drama. For example, bitter divorce litigation of a client might provide a backdrop for Ally's decision to break up with a boyfriend. Legal arguments were also frequently used to explore multiple sides of various social issues. + +Cage and Fish (which becomes Cage/Fish & McBeal or Cage, Fish, & Associates towards the end of the series), the fictional law firm where most of the characters work, is depicted as a highly sexualized environment symbolized by its unisex restroom. Lawyers and secretaries in the firm routinely date, flirt with, or have a romantic history with one another and frequently run into former or potential romantic interests in the courtroom or on the street outside. + +The series had many offbeat and frequently surreal running gags and themes, such as Ally's tendency to immediately fall over whenever she met somebody she found attractive, Richard Fish's wattle fetish and humorous mottos ("Fishisms" & "Bygones"), John's gymnastic dismounts out of the office's unisex bathroom stalls, or the dancing twins (played by Eric & Steve Cohen) at the bar, that ran through the series. The show also used vivid, dramatic fantasy sequences for Ally's and other characters' wishful thinking; of particular note is the early internet sensation the dancing baby. + +The series also featured regular visits to a local bar where singer Vonda Shepard regularly performed (though occasionally handing over the microphone to the characters). Star contemporary singers also performed in the bar at the end of the shows, including acts such as Mariah Carey, Barry White and Anastacia. The series also took place in the same continuity as David E. Kelley's legal drama The Practice (which aired on ABC), as the two shows crossed over with one another on occasion, a rare occurrence for two shows that aired on different networks. + +Ultimately, in the last installment of the fifth and final season, "Bygones", Ally decided to resign from Cage & Fish, leave Boston, and go to New York City. + +Cancellation +Fox canceled Ally McBeal after five seasons. In addition to being the lowest-rated season of Ally McBeal and the grounds for the show's cancellation, the fifth season was also the only season of the show that failed to win any Emmy or Golden Globe awards. + +Cast + +Recurring + Dyan Cannon as Jennifer "Whipper" Cone (Seasons 1–3) + Phil Leeds as Judge Dennis "Happy" Boyle (Seasons 1–2) + Jennifer Holliday as Lisa Knowles (Seasons 1–4) + Harrison Page as Reverend Mark Newman (Seasons 1–4) + Lee Wilkof as Districk Attorney Nixon (Seasons 1–2, 5) + Jesse L.

In 2010, it was aired repeatedly by Network 10. + +Crossovers with The Practice + +Seymore Walsh, a stern judge often exasperated by the eccentricities of the Cage & Fish lawyers and played by actor Albert Hall, was also a recurring character on The Practice. In addition, Judge Jennifer (Whipper) Cone appears on The Practice episode "Line of Duty" (S02 E15), while Judge Roberta Kittelson, a recurring character on The Practice, has a featured guest role in the Ally McBeal episode "Do you Wanna Dance?" + +Most of the primary Practice cast members guest starred in the Ally McBeal episode "The Inmates" (S01 E20), in a storyline that concluded with the Practice episode "Axe Murderer" (S02 E26), featuring Calista Flockhart and Gil Bellows reprising their Ally characters. Unusually for a TV crossover, Ally McBeal and The Practice aired on different networks. Bobby Donnell, the main character of The Practice played by Dylan McDermott, was featured heavily in both this crossover and another Ally McBeal episode, "These are the Days". + +Regular Practice cast members Lara Flynn Boyle and Michael Badalucco each had a cameo in Ally McBeal (Boyle as a woman who trades insults with Ally in the episode "Making Spirits Bright" and Badalucco as one of Ally's dates in the episode "I Know him by Heart") but it is unclear whether they were playing the same characters they play on The Practice. + +In Season 5, Lara Flynn Boyle had an uncredited guest appearance as a rebuttal witness opposite guest star Heather Locklear's character in the episode, "Tom Dooley". + +Filming location +14 Beacon Street in Boston was the exterior which was used as the location for the law firm "Cage & Fish" (later "Cage, Fish, & McBeal"), which was located on the 7th floor of this building. + +Reception +Upon premiering in 1997, the show was an instant hit, averaging around 11 million viewers per episode. The show's second season saw an increase in ratings and soon became a top 20 show, averaging around 13 million viewers per episode. The show's ratings began to decline in the third season, but stabilized in the fourth season after Robert Downey Jr. joined the regular cast as Ally's boyfriend Larry Paul, and a fresher aesthetic was created by new art director Matthew DeCoste. However, Downey's character was written out after the end of the season due to the actor's troubles with drug addiction. + +The first two seasons, as well as the fourth, remain the most critically acclaimed and saw the most awards success at the Emmys, SAG Awards and the Golden Globes. In 2007, Ally McBeal placed #48 on Entertainment Weekly 2007 "New TV Classics" list. + +Ratings + +Feminist criticism +Ally McBeal received some criticism from TV critics and feminists who found the title character annoying and demeaning to women (specifically regarding professional women) because of her perceived flightiness, lack of demonstrated legal knowledge, short skirts, and emotional instability. Perhaps the most notorious example of the debate sparked by the show was the June 29, 1998, cover story of Time magazine, which juxtaposed McBeal with three pioneering feminists (Susan B. Anthony, Betty Friedan, Gloria Steinem) and asked "Is Feminism Dead?" In episode 12 of the second season of the show, Ally talks to her co-worker John Cage about a dream she had, saying "You know, I had a dream that they put my face on the cover of Time magazine as 'the face of feminism'." + +Music + +Music was a prominent feature of Ally McBeal. Vonda Shepard, a relatively unknown musician at the time, performed regularly on the show and her song "Searchin' My Soul" was the show's theme song. Many of the songs Shepard performed were established hits with lyrics that paralleled the events of each episode, for example, "Both Sides Now", "Hooked on a Feeling" and "Tell Him". Besides recording background music for the show, Shepard frequently appeared at the ends of episodes as a musician performing at a local piano bar frequented by the main characters. On rare occasions, her character would have conventional dialogue. A portion of "Searchin' My Soul" was played at the beginning of each episode, but the song was never played in its entirety. + +Several of the characters had a musical leitmotif that played when they appeared. John Cage's was "You're the First, the Last, My Everything", Ling Woo's was the Wicked Witch of the West theme from The Wizard of Oz, and Ally McBeal herself picked "Tell Him", when told by a psychiatrist that she needed a theme song in a Season 1 episode. + +Due to the popularity of the show and Shepard's music, a soundtrack titled Songs from Ally McBeal was released in 1998, as well as a successor soundtrack titled Heart and Soul: New Songs from Ally McBeal in 1999. Two compilation albums from the show featuring Shepard were also released in 2000 and 2001. A Christmas album was also released under the title Ally McBeal: A Very Ally Christmas. The album received positive reviews, and Shephard's version of Kay Starr's Christmas song "(Everybody's Waitin' for) The Man with the Bag", received considerable airplay during the holiday season. + +Other artists featured on the show include Barry White, Al Green, Gladys Knight, Tina Turner, Macy Gray, Gloria Gaynor, Chayanne, Barry Manilow, Anastacia, Elton John, Sting and Mariah Carey. Josh Groban played the role of Malcolm Wyatt in the May 2001 season finale, performing "You're Still You". The series creator, David E. Kelley, was impressed with Groban's performance at The Family Celebration event and based on the audience reaction to Groban's singing, Kelley created a character for him in that finale. The background score for the show was composed by Danny Lux. + +Home media +Due to music licensing issues, none of the seasons of Ally McBeal were available on DVD in the United States until 2009, though the show had been available in Italy, Belgium, the Netherlands, Japan, Hong Kong, Portugal, Spain, France, Germany, the United Kingdom, Mexico, Taiwan, Australia, Brazil, and the Czech Republic with all the show's music intact since 2005. In the UK, Ireland, and Spain all seasons are available in a complete box set. + +20th Century Fox released the complete first season on DVD in Region 1 on October 6, 2009. They also released a special complete series edition on the same day. Season 1 does not contain any special features, but the complete series set contains several bonus features, including featurettes, an all-new retrospective, the episode of The Practice in which Calista Flockhart guest-starred, and a bonus disc entitled "The Best of Ally McBeal Soundtrack." In addition, both releases contain all of the original music. Season 2 was released on April 6, 2010. Seasons 3, 4, and 5 were all released on October 5, 2010. + +Ally (1999) +In 1999, at the height of the show's popularity, a half-hour version entitled Ally began airing in parallel with the main program. This version, designed in a sitcom format, used re-edited scenes from the main program, along with previously unseen footage. The intention was to further develop the plots in the comedy drama in a sitcom style. It also focused only on Ally's personal life, cutting all the courtroom plots. The repackaged show was cancelled partway through its initial run. While 13 episodes of Ally were produced, only ten aired. + +Possible revival +In March 2021, it was reported that a revival as a limited series was in early development by 20th Television with Flockhart possibly returning. + +In August 2022, it was reported that ABC was in early development of a sequel series with Karin Gist writing and executive producing. + +In popular culture + +In a third season episode of the British comedy The Adam and Joe Show, the show was parodied as "Ally McSqueal" using soft toys. + +A first season episode of the animated sitcom Futurama, "When Aliens Attack", centers on an invasion of Earth by the Omicronians precipitated by a signal loss during the climax of an episode of Single Female Lawyer, whose main character is Jenny McNeal. + +In a fourth season episode of the show The Good Place, the Judge hands Ted Danson's character a petition to reboot Ally McBeal, stating "everything else is getting rebooted." + +In the 2021 film The Mauritanian, Guantanamo Bay detention camp detainee Mohamedou Ould Salahi says to a US judge "Even in Mauritania, we have watched Law & Order and Ally McBeal." + +In a fourth season episode of the show Crazy Ex-Girlfriend, a lyric in the song "Don't Be a Lawyer", mentions the show "No one you work with looks like Ally McBeal". + +Awards and nominations + +References + +External links + + + + + + + Ally McBeal: Woman of the '90s or Retro Airhead + + +1997 American television series debuts +2002 American television series endings +1990s American comedy-drama television series +1990s American legal television series +1990s American romantic comedy television series +1990s American workplace comedy television series +1990s American workplace drama television series +1990s romantic drama television series +2000s American comedy-drama television series +2000s American legal television series +2000s American romantic comedy television series +2000s American workplace comedy television series +2000s American workplace drama television series +2000s romantic drama television series +American romantic drama television series +Best Musical or Comedy Series Golden Globe winners +English-language television shows +Fox Broadcasting Company original programming +Outstanding Performance by an Ensemble in a Comedy Series Screen Actors Guild Award winners +Peabody Award-winning television programs +Primetime Emmy Award for Outstanding Comedy Series winners +Primetime Emmy Award-winning television series +Television series by 20th Century Fox Television +Television series created by David E. Kelley +Television shows set in Boston +The Practice +Television series about lawyers +Andreas Capellanus (Capellanus meaning "chaplain"), also known as Andrew the Chaplain, and occasionally by a French translation of his name, André le Chapelain, was the 12th-century author of a treatise commonly known as De amore ("About Love"), and often known in English, somewhat misleadingly, as The Art of Courtly Love, though its realistic, somewhat cynical tone suggests that it is in some measure an antidote to courtly love. Little is known of Andreas Capellanus's life, but he is presumed to have been a courtier of Marie de Champagne, and probably of French origin. + +His work +De Amore was written at the request of Marie de Champagne, daughter of King Louis VII of France and of Eleanor of Aquitaine. In it, the author informs a young pupil, Walter, of the pitfalls of love. A dismissive allusion in the text to the "wealth of Hungary" has suggested the hypothesis that it was written after 1184, at the time when Bela III of Hungary had sent to the French court a statement of his income and had proposed marriage to Marie's half-sister Marguerite of France, but before 1186, when his proposal was accepted. + +De Amore is made up of three books. The first book covers the etymology and definition of love and is written in the manner of an academic lecture. The second book consists of sample dialogues between members of different social classes; it outlines how the romantic process between the classes should work. This second work is largely considered to be an inferior to the first. Book three is made of stories from actual courts of love presided over by noble women. + +John Jay Parry, the editor of one modern edition of De Amore, quotes critic Robert Bossuat as describing De Amore as "one of those capital works which reflect the thought of a great epoch, which explains the secret of a civilization". It may be viewed as didactic, mocking, or merely descriptive; in any event it preserves the attitudes and practices that were the foundation of a long and significant tradition in Western literature. + +The social system of "courtly love", as gradually elaborated by the Provençal troubadours from the mid twelfth century, soon spread. One of the circles in which this poetry and its ethic were cultivated was the court of Eleanor of Aquitaine (herself the granddaughter of an early troubadour poet, William IX of Aquitaine). De Amore codifies the social and love life of Eleanor's court at Poitiers between 1170 and 1174, though it was evidently written at least ten years later and, apparently, at Troyes. It deals with several specific themes that were the subject of poetical debate among late twelfth century troubadours and trobairitz. + +The meaning of De Amore has been debated over the centuries. In the years immediately following its release many people took Andreas' opinions concerning Courtly Love seriously. In more recent times, however, scholars have come to view the priest's work as satirical. Many scholars now agree that Andreas was commenting on the materialistic, superficial nature of medieval nobles. Andreas seems to have been warning young Walter, his protégé, about love in the Middle Ages. + +See also + Martianus Capella + Quadrivium + +Bibliography + Andreas Capellanus: The Art of Courtly Love, trans.

Current positions of the ACLU include opposing the death penalty; supporting same-sex marriage and the right of LGBT people to adopt; supporting reproductive rights such as birth control and abortion rights; eliminating discrimination against women, minorities, and LGBT people; decarceration in the United States; protecting housing and employment rights of veterans; reforming sex offender registries and protecting housing and employment rights of convicted first-time offenders; supporting the rights of prisoners and opposing torture; and upholding the separation of church and state by opposing government preference for religion over non-religion or for particular faiths over others. + +Legally, the ACLU consists of two separate but closely affiliated nonprofit organizations, namely the American Civil Liberties Union, a 501(c)(4) social welfare group; and the ACLU Foundation, a 501(c)(3) public charity. Both organizations engage in civil rights litigation, advocacy, and education, but only donations to the 501(c)(3) foundation are tax deductible, and only the 501(c)(4) group can engage in unlimited political lobbying. The two organizations share office space and employees. + +Overview +The ACLU was founded in 1920 by a committee including Roger Nash Baldwin, Crystal Eastman, Walter Nelles, Morris Ernst, Albert DeSilver, Arthur Garfield Hays, Helen Keller, Jane Addams, Felix Frankfurter, Elizabeth Gurley Flynn, and Rose Schneiderman. It focused on freedom of speech, primarily for anti-war protesters. It was founded in response to the controversial Palmer raids, which saw thousands of radicals arrested in manners that violated their constitutional search and seizures protection. During the 1920s, the ACLU expanded its scope to include protecting the free speech rights of artists and striking workers and working with the National Association for the Advancement of Colored People (NAACP) to mitigate discrimination. During the 1930s, the ACLU started to engage in work combating police misconduct and supporting Native American rights. Many of the ACLU's cases involved the defense of Communist Party members and Jehovah's Witnesses. In 1940, the ACLU leadership voted to exclude communists from its leadership positions, a decision rescinded in 1968. During World War II, the ACLU defended Japanese-American citizens, unsuccessfully trying to prevent their forcible relocation to internment camps. During the Cold War, the ACLU headquarters was dominated by anti-communists, but many local affiliates defended members of the Communist Party. + +By 1964, membership had risen to 80,000, and the ACLU participated in efforts to expand civil liberties. In the 1960s, the ACLU continued its decades-long effort to enforce separation of church and state. It defended several anti-war activists during the Vietnam War. The ACLU was involved in the Miranda case, which addressed conduct by police during interrogations, and in the New York Times case, which established new protections for newspapers reporting on government activities. In the 1970s and 1980s, the ACLU ventured into new legal areas involving the rights of homosexuals, students, prisoners, and the poor. In the twenty-first century, the ACLU has fought the teaching of creationism in public schools and challenged some provisions of anti-terrorism legislation as infringing on privacy and civil liberties. Fundraising and membership spiked after the 2016 presidential election, and the ACLU's 2018 membership was more than 1.2 million. + +Organization + +Leadership +The ACLU is led by a president and an executive director, Deborah N. Archer and Anthony Romero, respectively, in 2021. The president acts as chair of the ACLU's board of directors, leads fundraising, and facilitates policy-setting. The executive director manages the day-to-day operations of the organization. The board of directors consists of 80 persons, including representatives from each state affiliate and at-large delegates. The organization has its headquarters in 125 Broad Street, a 40-story skyscraper located in Lower Manhattan, New York City. + +The leadership of the ACLU does not always agree on policy decisions; differences of opinion within the ACLU leadership have sometimes grown into major debates. In 1937, an internal debate erupted over whether to defend Henry Ford's right to distribute anti-union literature. In 1939, a heated debate took place over whether to prohibit communists from serving in ACLU leadership roles. During the early 1950s and Cold War McCarthyism, the board was divided on whether to defend communists. In 1968, a schism formed over whether to represent Benjamin Spock's anti-war activism. In 1973, as the Watergate Scandal continued to unfold, leadership was initially divided over whether to call for President Nixon's impeachment and removal from office. In 2005, there was internal conflict about whether or not a gag rule should be imposed on ACLU employees to prevent the publication of internal disputes. + +Funding + +In the year ending March 31, 2014, the ACLU and the ACLU Foundation had a combined income from support and revenue of $100.4 million, originating from grants (50.0%), membership donations (25.4%), donated legal services (7.6%), bequests (16.2%), and revenue (0.9%). Membership dues are treated as donations; members choose the amount they pay annually, averaging approximately $50 per member. In the year ending March 31, 2014, the combined expenses of the ACLU and ACLU Foundation were $133.4 million, spent on programs (86.2%), management (7.4%), and fundraising (8.2%). (After factoring in other changes in net assets of +$30.9 million, from sources such as investment income, the organization had an overall decrease in net assets of $2.1 million.) Over the period from 2011 to 2014, the ACLU Foundation, on average, has accounted for roughly 70% of the combined budget, and the ACLU roughly 30%. + +The ACLU solicits donations to its charitable foundation. The ACLU is accredited by the Better Business Bureau, and the Charity Navigator has ranked the ACLU with a four-star rating. The local affiliates solicit their own funding; however, some also receive funds from the national ACLU, with the distribution and amount of such assistance varying from state to state. At its discretion, the national organization provides subsidies to smaller affiliates that lack sufficient resources to be self-sustaining; for example, the Wyoming ACLU chapter received such subsidies until April 2015, when, as part of a round of layoffs at the national ACLU, the Wyoming office was closed. + +In October 2004, the ACLU rejected $1.5 million from both the Ford Foundation and Rockefeller Foundation because the foundations had adopted language from the USA PATRIOT Act in their donation agreements, including a clause stipulating that none of the money would go to "underwriting terrorism or other unacceptable activities". The ACLU views this clause, both in federal law and in the donors' agreements, as a threat to civil liberties, saying it is overly broad and ambiguous. + +Due to the nature of its legal work, the ACLU is often involved in litigation against governmental bodies, which are generally protected from adverse monetary judgments; a town, state, or federal agency may be required to change its laws or behave differently, but not to pay monetary damages except by an explicit statutory waiver. In some cases, the law permits plaintiffs who successfully sue government agencies to collect money damages or other monetary relief. In particular, the Civil Rights Attorney's Fees Award Act of 1976 leaves the government liable in some civil rights cases. Fee awards under this civil rights statute are considered "equitable relief" rather than damages, and government entities are not immune from equitable relief. Under laws such as this, the ACLU and its state affiliates sometimes share in monetary judgments against government agencies. In 2006, the Public Expressions of Religion Protection Act sought to prevent monetary judgments in the particular case of violations of church-state separation. + +The ACLU has received court-awarded fees from opponents; for example, the Georgia affiliate was awarded $150,000 in fees after suing a county demanding the removal of a Ten Commandments display from its courthouse; a second Ten Commandments case in the state, in a different county, led to a $74,462 judgment. The State of Tennessee was required to pay $50,000, the State of Alabama $175,000, and the State of Kentucky $121,500, in similar Ten Commandments cases. + +State affiliates + +Most of the organization's workload is performed by its local affiliates. There is at least one affiliate organization in each state, as well as one in Washington, D.C., and in Puerto Rico. California has three affiliates. The affiliates operate autonomously from the national organization; each affiliate has its own staff, executive director, board of directors, and budget. Each affiliate consists of two non-profit corporations: a 501(c)(3) corporation–called the ACLU Foundation–that does not perform lobbying, and a 501(c)(4) corporation–called ACLU–which is entitled to lobby. Both organizations share staff and offices + +ACLU affiliates are the basic unit of the ACLU's organization and engage in litigation, lobbying, and public education. For example, in 2020, the ACLU's New Jersey chapter argued 26 cases before the New Jersey Supreme Court, about one-third of the total cases heard in that court. They sent over 50,000 emails to officials or agencies and had 28 full-time staff. + +Positions +The ACLU's official position statements included the following policies: + Affirmative action – The ACLU supports affirmative action. + Birth control and abortion – The ACLU supports the right to abortion, as established in the Roe v. Wade decision. The ACLU believes everyone should have affordable access to the full range of contraceptive options. The ACLU's Reproductive Freedom Project manages efforts related to reproductive rights. + Campaign funding – The ACLU believes the current system is badly flawed and supports a system based on public funding. The ACLU supports full transparency in identifying donors. However, the ACLU opposes attempts to control political spending. The ACLU supported the Supreme Court's decision in Citizens United v. FEC, which allowed corporations and unions more political speech rights. + Criminal law reform – The ACLU seeks an end to what it feels are excessively harsh sentences that "stand in the way of a just and equal society". The ACLU's Criminal Law Reform Project focuses on this issue. + Death penalty – The ACLU is opposed to the death penalty in all circumstances. The ACLU's Capital Punishment Project focuses on this issue. + Free speech – The ACLU supports free speech, including the right to express unpopular or controversial ideas, such as flag desecration, racist or sexist views, etc. However, a leaked ACLU memo from June 2018 said that speech that can "inflict serious harms" and "impede progress toward equality" may be a lower priority for the organization. + Gun rights – The national ACLU's position is that the Second Amendment protects a collective right to own guns rather than an individual right, despite the 2008 Supreme Court decision in District of Columbia v. Heller that the Second Amendment is a personal right. The national organization's position is based on the phrases "a well regulated Militia" and "the security of a free State". However, the ACLU opposes any effort to create a registry of gun owners and has worked with the National Rifle Association of America to prevent a registry from being created, and it has favored protecting the right to carry guns under the 4th Amendment. + HIV/AIDS – The policy of the ACLU is to "create a world in which discrimination based on HIV status has ended, people with HIV have control over their medical information and care, and where the government's HIV policy promotes public health and respect and compassion for people living with HIV and AIDS". The ACLU's AIDS Project manages this effort. + Human rights – The ACLU's Human Rights project advocates (primarily in an international context) for children's rights, disability rights, immigrant rights, gay rights, and other international obligations. + Immigrants' rights – The ACLU supports civil liberties for immigrants to the United States. + Lesbian, gay, bisexual and transgender rights – The ACLU supports equal rights for all lesbian, gay, bisexual, transgender, and queer people and works to eliminate discrimination. The ACLU supports equal employment, housing, civil marriage, and adoption rights for LGBT couples. + National security – The ACLU is opposed to compromising civil liberties in the name of national security. In this context, the ACLU has condemned government use of spying, indefinite detention without charge or trial, and government-sponsored torture. The ACLU's National Security Project leads this effort. + Prisoners' rights – The ACLU's National Prison Project believes that incarceration should only be used as a last resort and that prisons should focus on rehabilitation. The ACLU advocates that prisons treat prisoners according to the Constitution and domestic law. + Privacy and technology – The ACLU's Project on Speech, Privacy, and Technology promotes "responsible uses of technology that enhance privacy protection" and opposes uses "that undermine our freedoms and move us closer to a surveillance society". + Racial issues – The ACLU's Racial Justice Program combats racial discrimination in all aspects of society, including the educational system, the justice system, and the application of the death penalty. However, the ACLU opposes state censorship of the Confederate flag. + Religion – The ACLU supports the right of religious persons to practice their faiths without government interference. The ACLU believes the government should neither prefer religion over non-religion nor favor particular faiths over others. The ACLU is opposed to school-led prayer but protects students' right to pray in school. It opposes the use of religious beliefs to discriminate, such as refusing to provide abortion coverage or providing services to LGBT people. + Sex education – The ACLU opposes abstinence-only sex education curricula, and supports comprehensive sex education curricula that encourage effective contraceptive usage and sexually-transmitted disease prevention alongside waiting to have sex. The ACLU opposes segregation in sex education classes because it can lead to increased class size and perpetuate antiquated gender stereotypes. + Vaccination policy — The ACLU supports vaccine mandates for people using public facilities and businesses because there is no right to harm others by spreading infectious diseases. Hence, the ACLU states, mandates are "permissible in many settings where the unvaccinated pose a risk to others, including schools and universities, hospitals, restaurants and bars, workplaces and businesses open to the public". The organization supports a public health-based approach to pandemic management and is opposed to criminalizing or jailing people with infectious diseases. + Voting rights – The ACLU believes that impediments to voting should be eliminated, particularly if they disproportionately impact minority or poor citizens. The ACLU believes that misdemeanor convictions should not lead to a loss of voting rights. The ACLU's Voting Rights Project leads this effort. + Women's rights – The ACLU works to eliminate discrimination against women in all realms. The ACLU encourages the government to be proactive in stopping violence against women. These efforts are led by the ACLU's Women's Rights Project. + +Support and opposition +A variety of persons and organizations support the ACLU. There were over 1,000,000 members in 2017, and the ACLU receives thousands of grants from hundreds of charitable foundations annually. Allies of the ACLU in legal actions have included the National Association for the Advancement of Colored People, the American Jewish Congress, People for the American Way, the National Rifle Association of America, the Electronic Frontier Foundation, Americans United for Separation of Church and State and the National Organization for Women. + +The ACLU has been criticized by liberals such as when it excluded communists from its leadership ranks when it defended Neo-Nazis, when it declined to defend Paul Robeson, or when it opposed the passage of the National Labor Relations Act. In 2014, an ACLU affiliate supported anti-Islam protesters and in 2018 the ACLU was criticized when it supported the NRA. + +Conversely, it has been criticized by conservatives such as when it argued against official prayer in public schools or when it opposed the Patriot Act. + +The ACLU has supported conservative figures such as Rush Limbaugh, George Wallace, Henry Ford and Oliver North as well as liberal figures such as Dick Gregory, Rockwell Kent and Benjamin Spock. + +Major sources of criticism are legal cases in which the ACLU represents an individual or organization that promotes offensive or unpopular viewpoints, such as the Ku Klux Klan, neo-Nazis, the Nation of Islam, the North American Man/Boy Love Association, the Westboro Baptist Church or the Unite the Right rally. The ACLU's official policy is "... [we have] represented or defended individuals engaged in some truly offensive speech. We have defended the speech rights of communists, Nazis, Ku Klux Klan members, accused terrorists, pornographers, anti-LGBT activists, and flag burners. That's because the defense of freedom of speech is most necessary when the message is one most people find repulsive. Constitutional rights must apply to even the most unpopular groups if they're going to be preserved for everyone." + +Early years + +CLB era + +The ACLU developed from the National Civil Liberties Bureau (CLB), co-founded in 1917 during World War I by Crystal Eastman, an attorney activist, and Roger Nash Baldwin. The focus of the CLB was on freedom of speech, primarily anti-war speech, and on supporting conscientious objectors who did not want to serve in World War I. + +Three United States Supreme Court decisions in 1919 each upheld convictions under laws against certain anti-war speech. In 1919, the Court upheld the conviction of Socialist Party leader Charles Schenck for publishing anti-war literature. In Debs v. United States, the court upheld the conviction of Eugene Debs. While the Court upheld a conviction a third time in Abrams v. United States, Justice Oliver Wendell Holmes wrote an important dissent which has gradually been absorbed as an American principle: he urged the court to treat freedom of speech as a fundamental right, which should rarely be restricted. + +In 1918, Crystal Eastman resigned from the organization due to health issues. After assuming sole leadership of the CLB, Baldwin insisted that the organization be reorganized. He wanted to change its focus from litigation to direct action and public education. + +The CLB directors concurred, and on January 19, 1920, they formed an organization under a new name, the American Civil Liberties Union. Although a handful of other organizations in the United States at that time focused on civil rights, such as the National Association for the Advancement of Colored People (NAACP) and Anti-Defamation League (ADL), the ACLU was the first that did not represent a particular group of persons or a single theme. Like the CLB, the NAACP pursued litigation to work on civil rights, including efforts to overturn the disfranchisement of African Americans in the South that had taken place since the turn of the century. + +During the first decades of the ACLU, Baldwin continued as its leader. His charisma and energy attracted many supporters to the ACLU board and leadership ranks. Baldwin was ascetic, wearing hand-me-down clothes, pinching pennies, and living on a minimal salary. The ACLU was directed by an executive committee and was not particularly democratic or egalitarian. New Yorkers dominated the ACLU's headquarters. Most ACLU funding came from philanthropies, such as the Garland Fund. + +Free speech era +In the 1920s, government censorship was commonplace. Magazines were routinely confiscated under the anti-obscenity Comstock laws; permits for labor rallies were often denied; and virtually all anti-war or anti-government literature was outlawed. Right-wing conservatives wielded vast amounts of power, and activists that promoted unionization, socialism, or government reform were often denounced as un-American or unpatriotic. In one typical instance in 1923, author Upton Sinclair was arrested for trying to read the First Amendment during an Industrial Workers of the World rally. + +ACLU leadership was divided on how to challenge civil rights violations. One faction, including Baldwin, Arthur Garfield Hays, and Norman Thomas, believed that direct, militant action was the best path. Hays was the first of many successful attorneys that relinquished their private practices to work for the ACLU. Another group, including Walter Nelles and Walter Pollak, felt that lawsuits taken to the Supreme Court were the best way to achieve change. + +During the 1920s, the ACLU's primary focus was on freedom of speech in general and speech within the labor movement particularly. Because most of the ACLU's efforts were associated with the labor movement, the ACLU itself came under heavy attack from conservative groups, such as the American Legion, the National Civic Federation, and Industrial Defense Association and the Allied Patriotic Societies. + +In addition to labor, the ACLU also led efforts in non-labor arenas, for example, promoting free speech in public schools. The ACLU was banned from speaking in New York public schools in 1921. The ACLU, working with the NAACP, also supported racial discrimination cases. The ACLU defended free speech regardless of espoused opinions. For example, the reactionary, anti-Catholic, anti-black Ku Klux Klan (KKK) was a frequent target of ACLU efforts, but the ACLU defended the KKK's right to hold meetings in 1923. There were some civil rights that the ACLU did not make an effort to defend in the 1920s, including censorship of the arts, government search and seizure issues, right to privacy, or wiretapping. + +Government officials routinely hounded the Communist Party USA, leading it to be the primary client of the ACLU. At the same time, the Communists were very aggressive in their tactics, often engaging in illegal conduct such as denying their party membership under oath. This led to frequent conflicts between the Communists and ACLU. Communist leaders sometimes attacked the ACLU, particularly when the ACLU defended the free speech rights of conservatives, whereas Communists tried to disrupt speeches by critics of the USSR. This uneasy relationship between the two groups continued for decades. + +Public schools + +Scopes trial +When 1925 arrived five years after the ACLU was formed the organization had virtually no success to show for its efforts. That changed in 1925, when the ACLU persuaded John T. Scopes to defy Tennessee's anti-evolution law in The State of Tennessee v. John Thomas Scopes. Clarence Darrow, a member of the ACLU National Committee, headed Scopes' legal team. The prosecution, led by William Jennings Bryan, contended that the Bible should be interpreted literally in teaching creationism in school. The ACLU lost the case, and Scopes was fined $100. The Tennessee Supreme Court later upheld the law. Still, it overturned the conviction on a technicality. + +The Scopes trial was a phenomenal public relations success for the ACLU. The ACLU became well known across America, and the case led to the first endorsement of the ACLU by a major US newspaper. The ACLU continued to fight for the separation of church and state in schoolrooms, decade after decade, including the 1982 case McLean v. Arkansas and the 2005 case Kitzmiller v. Dover Area School District. + +Baldwin was involved in a significant free speech victory of the 1920s after he was arrested for attempting to speak at a rally of striking mill workers in New Jersey. Although the decision was limited to the state of New Jersey, the appeals court's judgment in 1928 declared that constitutional guarantees of free speech must be given "liberal and comprehensive construction", and it marked a major turning point in the civil rights movement, signaling the shift of judicial opinion in favor of civil rights. + +The most important ACLU case of the 1920s was Gitlow v. New York, in which Benjamin Gitlow was arrested for violating a state law against inciting anarchy and violence when he distributed literature promoting communism. Although the Supreme Court did not overturn Gitlow's conviction, it adopted the ACLU's stance (later termed the incorporation doctrine) that the First Amendment freedom of speech applied to state laws, as well as federal laws. + +Pierce v. Society of Sisters + +After the First World War, many native-born Americans had a revival of concerns about the assimilation of immigrants and worries about "foreign" values; they wanted public schools to teach children to be American. Numerous states drafted laws designed to use schools to promote a common American culture, and in 1922, the voters of Oregon passed the Oregon Compulsory Education Act. The law was primarily aimed at eliminating parochial schools, including Catholic schools. It was promoted by groups such as the Knights of Pythias, the Federation of Patriotic Societies, the Oregon Good Government League, the Orange Order, and the Ku Klux Klan. + +The Oregon Compulsory Education Act required almost all children in Oregon between eight and sixteen years of age to attend public school by 1926. Associate Director Roger Nash Baldwin, a personal friend of Luke E. Hart, the then–Supreme Advocate and future Supreme Knight of the Knights of Columbus, offered to join forces with the Knights to challenge the law. The Knights of Columbus pledged an immediate $10,000 to fight the law and any additional funds necessary to defeat it. + +The case became known as Pierce v. Society of Sisters, a seminal United States Supreme Court decision that significantly expanded coverage of the Due Process Clause in the Fourteenth Amendment. In a unanimous decision, the court held that the act was unconstitutional and that parents, not the state, had the authority to educate children as they thought best. It upheld the religious freedom of parents to educate their children in religious schools. + +Early strategy +Leaders of the ACLU were divided on the best tactics to use to promote civil liberties. Felix Frankfurter felt that legislation was the best long-term solution because the Supreme Court could not (and in his opinion should not) mandate liberal interpretations of the Bill of Rights. But Walter Pollak, Morris Ernst, and other leaders felt that Supreme Court decisions were the best path to guarantee civil liberties. A series of Supreme Court decisions in the 1920s foretold a changing national atmosphere; anti-radical emotions were diminishing, and there was a growing willingness to protect freedom of speech and assembly via court decisions. + +Free speech expansion + +Censorship was commonplace in the early 20th century. State laws and city ordinances routinely outlawed speech deemed obscene or offensive and prohibited meetings or literature promoting unions or labor organizations. Starting in 1926, the ACLU expanded its free speech activities to encompass censorship of art and literature. In that year, H. L. Mencken deliberately broke Boston law by distributing copies of his banned American Mercury magazine; the ACLU defended him and won an acquittal. The ACLU went on to win additional victories, including the landmark case United States v. One Book Called Ulysses in 1933, which reversed a ban by the Customs Department against the book Ulysses by James Joyce. The ACLU only achieved mixed results in the early years, and it was not until 1966 that the Supreme Court finally clarified the obscenity laws in the Roth v. United States and Memoirs v. Massachusetts cases. + +The Comstock laws banned the distribution of sex education information based on the premise that it was obscene and led to promiscuous behavior. Mary Ware Dennett was fined $300 in 1928 for distributing a pamphlet containing sex education material. The ACLU, led by Morris Ernst, appealed her conviction and won a reversal, in which judge Learned Hand ruled that the pamphlet's primary purpose was to "promote understanding". + +The success prompted the ACLU to broaden their freedom of speech efforts beyond labor and political speech to encompass movies, press, radio, and literature. The ACLU formed the National Committee on Freedom from Censorship in 1931 to coordinate this effort. By the early 1930s, censorship in the United States was diminishing. + +Two major victories in the 1930s cemented the ACLU's campaign to promote free speech. In Stromberg v. California, decided in 1931, the Supreme Court sided with the ACLU and affirmed the right of a communist party member to salute a communist flag. The result was the first time the Supreme Court used the Due Process Clause of the 14th amendment to subject states to the requirements of the First Amendment. In Near v. Minnesota, also decided in 1931, the Supreme Court ruled that states may not exercise prior restraint and prevent a newspaper from publishing, simply because the newspaper had a reputation for being scandalous. + +1930s +The late 1930s saw the emergence of a new era of tolerance in the United States. National leaders hailed the Bill of Rights, particularly as it protected minorities, as the essence of democracy. The 1939 Supreme Court decision in Hague v. Committee for Industrial Organization affirmed the right of communists to promote their cause. Even conservative elements, such as the American Bar Association, began to campaign for civil liberties, which were long considered to be the domain of left-leaning organizations. By 1940, the ACLU had achieved many of the goals it set in the 1920s, and many of its policies were the law of the land. + +Expansion +In 1929, after the Scopes and Dennett victories, Baldwin perceived that there was vast, untapped support for civil liberties in the United States. Baldwin proposed an expansion program for the ACLU, focusing on police brutality, Native American rights, African American rights, censorship in the arts, and international civil liberties. The board of directors approved Baldwin's expansion plan, except for the international efforts. + +The ACLU played a significant role in passing the 1932 Norris–La Guardia Act, a federal law that prohibited employers from preventing employees from joining unions and stopped the practice of outlawing strikes, marriages, and labor organizing activities with the use of injunctions. The ACLU also played a key role in initiating a nationwide effort to reduce misconduct (such as extracting false confessions) within police departments by publishing the report Lawlessness in Law Enforcement in 1931, under the auspices of Herbert Hoover's Wickersham Commission. In 1934, the ACLU lobbied for the passage of the Indian Reorganization Act, which restored some autonomy to Native American tribes, and established penalties for kidnapping Native American children. + +Although the ACLU deferred to the NAACP for litigation promoting civil liberties for African Americans, the ACLU engaged in educational efforts and published Black Justice in 1931, a report which documented institutional racism throughout the South, including lack of voting rights, segregation, and discrimination in the justice system. Funded by the Garland Fund, the ACLU also participated in producing the influential Margold Report, which outlined a strategy to fight for civil rights for blacks. The ACLU planned to demonstrate that the "separate but equal" policies governing the Southern discrimination were illegal because blacks were never, in fact, treated equally. + +Depression era and the New Deal +In 1932twelve years after the ACLU was foundedit had achieved significant success; the Supreme Court had embraced the free speech principles espoused by the ACLU, and the general public was becoming more supportive of civil rights in general. But the Great Depression brought new assaults on civil liberties; the year 1930 saw a large increase in the number of free speech prosecutions, a doubling of the number of lynchings, and all meetings of unemployed persons were banned in Philadelphia. + +The Franklin D. Roosevelt administration proposed the New Deal to combat the depression. ACLU leaders were of mixed opinions about the New Deal since many felt that it represented an increase in government intervention into personal affairs and because the National Recovery Administration suspended antitrust legislation. Roosevelt was not personally interested in civil rights but did appoint many civil libertarians to key positions, including Interior Secretary Harold Ickes, a member of the ACLU. + +The economic policies of the New Deal leaders were often aligned with ACLU goals, but social goals were not. In particular, movies were subject to a barrage of local ordinances that banned screenings deemed immoral or obscene. Even public health films portraying pregnancy and birth were banned, as was Life magazine's April 11, 1938, issue, which included photos of the birth process. The ACLU fought these bans but did not prevail. + +The Catholic Church attained increasing political influence in the 1930s; it used its influence to promote the censorship of movies and to discourage the publication of birth control information. This conflict between the ACLU and the Catholic Church led to the resignation of the last Catholic priest from ACLU leadership in 1934; a Catholic priest would not be represented again until the 1970s. + +The ACLU took no official position on president Franklin Delano Roosevelt's 1937 court-packing plan, which threatened to increase the number of Supreme Court justices unless the Supreme Court reversed its course and began approving New Deal legislation. The Supreme Court responded by making a major shift in policy, and no longer applied strict constitutional limits to government programs, and also began to take a more active role in protecting civil liberties. + +The first decision that marked the court's new direction was De Jonge v. Oregon, in which a communist labor organizer was arrested for calling a meeting to discuss unionization. The ACLU attorney Osmond Fraenkel, working with International Labor Defense, defended De Jonge in 1937 and won a major victory when the Supreme Court ruled that "peaceable assembly for lawful discussion cannot be made a crime." The De Jonge case marked the start of an era lasting for a dozen years, during which Roosevelt appointees (led by Hugo Black, William O. Douglas, and Frank Murphy) established a body of civil liberties law. In 1938, Justice Harlan F. Stone wrote the famous "footnote four" in United States v. Carolene Products Co. in which he suggested that state laws which impede civil liberties wouldhenceforthrequire compelling justification. + +Senator Robert F. Wagner proposed the National Labor Relations Act in 1935, which empowered workers to unionize. Ironically, after 15 years of fighting for workers' rights, the ACLU initially opposed the act (it later took no stand on the legislation) because some ACLU leaders feared the increased power the bill gave to the government. The newly formed National Labor Relations Board (NLRB) posed a dilemma for the ACLU because, in 1937, it issued an order to Henry Ford, prohibiting Ford from disseminating anti-union literature. Part of the ACLU leadership habitually took the side of labor, and that faction supported the NLRB's action. But part of the ACLU supported Ford's right to free speech. ACLU leader Arthur Garfield Hays proposed a compromise (supporting the auto workers union, yet also endorsing Ford's right to express personal opinions), but the schism highlighted a deeper divide that would become more prominent in the years to come. + +The ACLU's support of the NLRB was a significant development for the ACLU because it marked the first time it accepted that a government agency could be responsible for upholding civil liberties. Until 1937, the ACLU felt that citizens and private organizations best upheld civil rights. + +Some factions in the ACLU proposed new directions for the organization. In the late 1930s, some local affiliates proposed shifting their emphasis from civil liberties appellate actions to becoming a legal aid society centered on store front offices in low-income neighborhoods. The ACLU directors rejected that proposal. Other ACLU members wanted the ACLU to shift focus into the political arena and be more willing to compromise their ideals to strike deals with politicians. The ACLU leadership also rejected this initiative. + +Jehovah's Witnesses +The ACLU's support of defendants with unpopular, sometimes extreme, viewpoints has produced many landmark court cases and established new civil liberties. One such defendant was the Jehovah's Witnesses, who were involved in a large number of Supreme Court cases. Cases that the ACLU supported included Lovell v. City of Griffin (which struck down a city ordinance that required a permit before a person could distribute "literature of any kind"); Martin v. Struthers (which struck down an ordinance prohibiting door-to-door canvassing); and Cantwell v. Connecticut (which reversed the conviction of a Witness who was reciting offensive speech on a street corner). + +The most important cases involved statutes requiring flag salutes. The Jehovah's Witnesses felt that saluting a flag was contrary to their religious beliefs. Two children were convicted in 1938 of not saluting the flag. The ACLU supported their appeal to the Supreme Court, but the court affirmed the conviction in 1940. But three years later, in West Virginia State Board of Education v. Barnette, the Supreme court reversed itself and wrote, "If there is any fixed star in our constitutional constellation, it is that no official, high or petty, can prescribe what shall be orthodox in politics, nationalism, religion, or other matters of opinion or force citizens to confess by word or act their faith therein." To underscore its decision, the Supreme Court announced it on Flag Day. + +Communism and totalitarianism + +The rise of totalitarian regimes in Germany, Russia, and other countries that rejected freedom of speech and association greatly impacted the civil liberties movement in the US; anti-Communist sentiment rose, and civil liberties were curtailed. + +The ACLU leadership was divided over whether or not to defend pro-Nazi speech in the United States; pro-labor elements within the ACLU were hostile towards Nazism and fascism and objected when the ACLU defended Nazis. Several states passed laws outlawing hate speech directed at ethnic groups. The first person arrested under New Jersey's 1935 hate speech law was a Jehovah's Witness who was charged with disseminating anti-Catholic literature. The ACLU defended the Jehovah's Witnesses, and the charges were dropped. The ACLU defended numerous pro-Nazi groups, defending their rights to free speech and free association. + +In the late 1930s, the ACLU allied itself with the Popular Front, a coalition of liberal organizations coordinated by the United States Communist Party. The ACLU benefited because affiliates from the Popular Front could often fight local civil rights battles much more effectively than the New York-based ACLU. The association with the Communist Party led to accusations that the ACLU was a "Communist front", particularly because Harry F. Ward was both chairman of the ACLU and chairman of the American League Against War and Fascism, a Communist organization. + +The House Un-American Activities Committee (HUAC) was created in 1938 to uncover sedition and treason within the United States. When witnesses testified at its hearings, the ACLU was mentioned several times, leading the HUAC to mention the ACLU prominently in its 1939 report. This damaged the ACLU's reputation severely, even though the report said that it could not "definitely state whether or not" the ACLU was a Communist organization. + +While the ACLU rushed to defend its image against allegations of being a Communist front, it also protected witnesses harassed by the HUAC. The ACLU was one of the few organizations to protest (unsuccessfully) against the passage of the Smith Act in 1940, which would later be used to imprison many persons who supported Communism. The ACLU defended many persons who were prosecuted under the Smith Act, including labor leader Harry Bridges. + +ACLU leadership was split on whether to purge its leadership of Communists. Norman Thomas, John Haynes Holmes, and Morris Ernst were anti-Communists who wanted to distance the ACLU from Communism; opposing them were Harry F. Ward, Corliss Lamont, and Elizabeth Gurley Flynn, who rejected any political test for ACLU leadership. A bitter struggle ensued throughout 1939, and the anti-Communists prevailed in February 1940 when the board voted to prohibit anyone who supported totalitarianism from ACLU leadership roles. Ward immediately resigned, andfollowing a contentious six-hour debateFlynn was voted off the ACLU's board. The 1940 resolution was considered by many to be a betrayal of its fundamental principles. The resolution was rescinded in 1968, and Flynn was posthumously reinstated to the ACLU in 1970. + +Mid-century + +World War II +When World War II engulfed the United States, the Bill of Rights was enshrined as a hallowed document, and numerous organizations defended civil liberties. Chicago and New York proclaimed "Civil Rights" weeks, and President Franklin Delano Roosevelt announced a national Bill of Rights day. Eleanor Roosevelt was the keynote speaker at the 1939 ACLU convention. Despite this newfound respect for civil rights, Americans were becoming adamantly anti-communist and believed that excluding communists from American society was an essential step to preserve democracy. + +Contrasted to World War I, there was relatively little violation of civil liberties during World War II. President Roosevelt was a strong supporter of civil liberties, butmore importantlythere were few anti-war activists during World War II. The most significant exception was the internment of Japanese Americans. + +Japanese American internment + +Two months after the Japanese attack on Pearl Harbor, Roosevelt authorized the creation of military "exclusion zones" with Executive Order 9066, paving the way for the detention of all West Coast Japanese Americans in inland camps. In addition to the non-citizen Issei (prohibited from naturalization as members of an "unassimilable" race), over two-thirds of those swept up were American-born citizens. The ACLU immediately protested to Roosevelt, comparing the evacuations to Nazi concentration camps. The ACLU was the only major organization to object to the internment plan, and their position was very unpopular, even within the organization. Not all ACLU leaders wanted to defend the Japanese Americans; Roosevelt loyalists such as Morris Ernst wanted to support Roosevelt's war effort, but pacifists such as Baldwin and Norman Thomas felt that Japanese Americans needed access to due process before they could be imprisoned. In a March 20, 1942, letter to Roosevelt, Baldwin called on the administration to allow Japanese Americans to prove their loyalty at individual hearings, describing the constitutionality of the planned removal "open to grave question". His suggestions went nowhere, and opinions within the organization became increasingly divided as the Army began the "evacuation" of the West Coast. In May, the two factions, one pushing to fight the exclusion orders then being issued, the other advocating support for the President's policy of removing citizens whose "presence may endanger national security", brought their opposing resolutions to a vote before the board and the ACLU's national leaders. They decided not to challenge the eviction of Japanese American citizens; on June 22, instructions were sent to West Coast branches not to support cases that argued the government had no constitutional right to do so. + +The ACLU offices on the West Coast had been more directly involved in addressing the tide of anti-Japanese prejudice from the start, as they were geographically closer to the issue and were already working on cases challenging the exclusion by this time. The Seattle office, assisting in Gordon Hirabayashi's lawsuit, created an unaffiliated committee to continue the work the ACLU had started, while in Los Angeles, attorney A.L. Wirin continued to represent Ernest Kinzo Wakayama but without addressing the case's constitutional questions. Wirin would lose private clients because of his defense of Wakayama and other Japanese Americans; however, the San Francisco branch, led by Ernest Besig, refused to discontinue its support for Fred Korematsu, whose case had been taken on before the June 22 directive, and attorney Wayne Collins, with Besig's full support, centered his defense on the illegality of Korematsu's exclusion. + +The West Coast offices had wanted a test case to take to court. However, they had a difficult time finding a Japanese American who was both willing to violate the internment orders and able to meet the ACLU's desired criteria of a sympathetic, Americanized plaintiff. Of the 120,000 Japanese Americans affected by the order, only 12 disobeyed, and Korematsu, Hirabayashi, and two others were the only resisters whose cases eventually made it to the Supreme Court. Hirabayashi v. United States came before the Court in May 1943, and the justices upheld the government's right to exclude Japanese Americans from the West Coast; although it had earlier forced its local office in L.A. to stop aiding Hirabayashi, the ACLU donated $1,000 to the case (over a third of the legal team's total budget) and submitted an amicus brief. Besig, dissatisfied with Osmond Fraenkel's tamer defense, filed an additional amicus brief that directly addressed Hirabayashi's constitutional rights. In the meantime, A.L. Wirin served as one of the attorneys in Yasui v. United States (decided the same day as the Hirabayashi case and with the same results). Still, he kept his arguments within the national office's parameters. The only case to receive a favorable ruling, ex parte Endo, was also aided by two amicus briefs from the ACLU, one from the more conservative Fraenkel and another from the more putative Wayne Collins. + +Korematsu v. United States proved to be the most controversial of these cases, as Besig and Collins refused to bow to the national ACLU office's pressure to pursue the case without challenging the government's right to remove citizens from their homes. The ACLU board threatened to revoke the San Francisco branch's national affiliation. At the same time, Baldwin tried unsuccessfully to convince Collins to step down so he could replace him as lead attorney in the case. Eventually, Collins agreed to present the case alongside Charles Horsky; however, their arguments before the Supreme Court remained based on the unconstitutionality of the exclusion order Korematsu had disobeyed. The case was decided in December 1944, when the Court once again upheld the government's right to relocate Japanese Americans, although Korematsu's, Hirabayashi's and Yasui's convictions were later overturned in coram nobis proceedings in the 1980s. Legal scholar Peter Irons later asserted that the national office of the ACLU's decision not to challenge the constitutionality of Executive Order 9066 directly had "crippled the effective presentation of these appeals to the Supreme Court". + +The national office of the ACLU was even more reluctant to defend anti-war protesters. A majority of the board passed a resolution in 1942 that declared the ACLU unwilling to defend anyone who interfered with the United States' war effort. Included in this group were the thousands of Nisei who renounced their US citizenship during the war but later regretted the decision and tried to revoke their applications for "repatriation". (A significant number of those slated to "go back" to Japan had never actually been to the country and were being deported rather than repatriated.) Ernest Besig had in 1944 visited the Tule Lake Segregation Center, where the majority of these "renunciants" were concentrated, and subsequently enlisted Wayne Collins' help to file a lawsuit on their behalf, arguing the renunciations had been given under duress. The national organization prohibited local branches from representing the renunciants, forcing Collins to pursue the case independently, although Besig and the Northern California office provided some support. + +During his 1944 visit to Tule Lake, Besig had also become aware of a hastily constructed stockade in which Japanese American internees were routinely being brutalized and held for months without due process. The national ACLU office forbade Besig to intervene on behalf of the stockade prisoners or even to visit the Tule Lake camp without prior written approval from Baldwin. Unable to help directly, Besig turned to Wayne Collins for assistance. Using the threat of habeas corpus suits, Collins managed to have the stockade closed down. A year later, after learning that the stockade had been reestablished, he returned to the camp and had it closed down for good. + +End of WWII in 1945 +When the war ended in 1945, the ACLU was 25 years old and had accumulated impressive legal victories. President Harry S. Truman sent a congratulatory telegram to the ACLU on the occasion of their 25th anniversary. American attitudes had changed since World War I, and dissent by minorities was tolerated with more willingness. The Bill of Rights was more respected, and minority rights were becoming more commonly championed. During their 1945 annual conference, the ACLU leaders composed a list of important civil rights issues to focus on in the future, including racial discrimination and separation of church and state. + +The ACLU supported the African-American defendants in Shelley v. Kraemer, when they tried to occupy a house they had purchased in a neighborhood with racially restrictive housing covenants. The African-American purchasers won the case in 1945. + +Cold War era +Anti-Communist sentiment gripped the United States during the Cold War beginning in 1946. Federal investigations caused many persons with Communist or left-leaning affiliations to lose jobs, become blocklisted, or be jailed. During the Cold War, although the United States collectively ignored the civil rights of Communists, other civil libertiessuch as due process in law and separation of church and statecontinued to be reinforced and even expanded. + +The ACLU was internally divided when it purged Communists from its leadership in 1940, and that ambivalence continued as it decided whether to defend alleged Communists during the late 1940s. Some ACLU leaders were anti-Communist and felt that the ACLU should not defend any victims. Some ACLU leaders felt that Communists were entitled to free speech protections and that the ACLU should defend them. Other ACLU leaders were uncertain about the threat posed by Communists and tried to establish a compromise between the two extremes. This ambivalent state of affairs would last until 1954, when the civil liberties faction prevailed, leading to most anti-Communist leaders' resignations. + +In 1947, President Truman issued Executive Order 9835, which created the Federal Loyalty Program. This program authorized the Attorney General to create a list of organizations that were deemed to be subversive. Any association with these programs was ground for barring the person from employment. Listed organizations were not notified that they were being considered for the list, nor did they have an opportunity to present counterarguments; nor did the government divulge any factual basis for inclusion in the list. Although ACLU leadership was divided on whether to challenge the Federal Loyalty Program, some challenges were successfully made. + +Also in 1947, the House Un-American Activities Committee (HUAC) subpoenaed ten Hollywood directors and writers, the Hollywood Ten, intending to ask them to identify Communists, but the witnesses refused to testify. All were imprisoned for contempt of Congress. The ACLU supported several artists' appeals but lost on appeal. The Hollywood establishment panicked after the HUAC hearings and created a blacklist that prohibited anyone with leftist associations from working. The ACLU supported legal challenges to the blocklist, but those challenges failed. The ACLU was more successful with an education effort; the 1952 report The Judges and the Judged, prepared at the ACLU's direction in response to the blocklisting of actress Jean Muir, described the unfair and unethical actions behind the blocklisting process, and it helped gradually turn public opinion against McCarthyism. + +The federal government took direct aim at the US Communist Party in 1948 when it indicted its top twelve leaders in the Foley Square trial. The case hinged on whether or not mere membership in a totalitarian political party was sufficient to conclude that members advocated the overthrow of the United States government. The ACLU chose not to represent any of the defendants, and they were all found guilty and sentenced to three to five years in prison. Their defense attorneys were all cited for contempt, went to prison, and were disbarred. When the government indicted additional party members, the defendants could not find attorneys to represent them. Communists protested outside the courthouse; a bill to outlaw picketing of courthouses was introduced in Congress, and the ACLU supported the anti-picketing law. + +In a change of heart, the ACLU supported the party leaders during their appeal process. The Supreme Court upheld the convictions in the Dennis v. United States decision by softening the free speech requirements from a "clear and present danger" test to a "grave and probable" test. The ACLU issued a public condemnation of the Dennis decision, and resolved to fight it. One reason for the Supreme Court's support of Cold War legislation was the 1949 deaths of Supreme Court justices Frank Murphy and Wiley Rutledge, leaving Hugo Black and William O. Douglas as the only remaining civil libertarians on the Court. + +The Dennis decision paved the way for the prosecution of hundreds of other Communist party members. The ACLU supported many Communists during their appeals (although most of the initiative originated with local ACLU affiliates, not the national headquarters), but most convictions were upheld. The two California affiliates, in particular, felt the national ACLU headquarters was not supporting civil liberties strongly enough, and they initiated more cold war cases than the national headquarters did. + +The ACLU challenged many loyalty oath requirements across the country, but the courts upheld most loyalty oath laws. California ACLU affiliates successfully challenged the California state loyalty oath. The Supreme Court, until 1957, upheld nearly every law which restricted the liberties of Communists. + +The ACLU, even though it scaled back its defense of Communists during the Cold War, still came under heavy criticism as a "front" for Communism. Critics included the American Legion, Senator Joseph McCarthy, the HUAC, and the FBI. Several ACLU leaders were sympathetic to the FBI, and as a consequence, the ACLU rarely investigated any of the many complaints alleging abuse of power by the FBI during the Cold War. + +In 1950, Raymond L. Wise, ACLU board member 1933–1951, defended William Perl, one of the other spies embroiled in the atomic espionage cases (made famous by the execution of Julius Rosenberg and Ethel Rosenberg). However, the ACLU publicly endorsed the guilty verdict in the Rosenberg case. The ACLU took the position that the execution of the Rosenbergs did not involve a civil rights issue. + +Organizational change +In 1950, the ACLU board of directors asked executive director Baldwin to resign, feeling he lacked the organizational skills to lead the 9,000 (and growing) member organization. Baldwin objected, but a majority of the board elected to remove him from the position, and he was replaced by Patrick Murphy Malin. Under Malin's guidance, membership tripled to 30,000 by 1955the start of 24 years of continual growth leading to 275,000 members in 1974. Malin also presided over an expansion of local ACLU affiliates. + +The ACLU, controlled by an elite of a few dozen New Yorkers, became more democratic in the 1950s. In 1951, the ACLU amended its bylaws to permit the local affiliates to participate directly in voting on ACLU policy decisions. A bi-annual conference, open to the entire membership, was instituted in the same year; in later decades, it became a pulpit for activist members, who suggested new directions for the ACLU, including abortion rights, death penalty, and rights of the poor. + +McCarthy era + +During the early 1950s, the ACLU continued to steer a moderate course through the Cold War. When singer Paul Robeson was denied a passport in 1950, even though he was not accused of any illegal acts, the ACLU chose not to defend him. The ACLU later reversed their stance and supported William Worthy and Rockwell Kent in their passport confiscation cases, which resulted in legal victories in the late 1950s. + +In response to communist witch-hunts, many witnesses and employees chose to use the fifth amendment protection against self-incrimination to avoid divulging information about their political beliefs. Government agencies and private organizations, in response, established policies which inferred communist party membership for anyone who invoked the fifth amendment. The national ACLU was divided on whether to defend employees who had been fired merely for pleading the fifth amendment, but the New York affiliate successfully assisted teacher Harry Slochower in his Supreme Court case, which reversed his termination. + +The fifth amendment issue became the catalyst for a watershed event in 1954, which finally resolved the ACLU's ambivalence by ousting the anti-communists from ACLU leadership. In 1953, the anti-communists, led by Norman Thomas and James Fly, proposed a set of resolutions that inferred guilt of persons that invoked the fifth amendment. These resolutions were the first that fell under the ACLU's new organizational rules permitting local affiliates to participate in the vote; the affiliates outvoted the national headquarters and rejected the anti-communist resolutions. Anti-communist leaders refused to accept the results of the vote and brought the issue up for discussion again at the 1954 bi-annual convention. ACLU member Frank Graham, president of the University of North Carolina, attacked the anti-communists with a counter-proposal, which stated that the ACLU "stand[s] against guilt by association, judgment by accusation, the invasion of privacy of personal opinions and beliefs, and the confusion of dissent with disloyalty". The anti-communists continued to battle Graham's proposal but were outnumbered by the affiliates. The anti-communists finally gave up and departed the board of directors in late 1954 and 1955, ending an eight-year ambivalence within the ACLU leadership ranks. After that, the ACLU proceeded with firmer resolve against Cold War anti-communist legislation. The period from the 1940 resolution (and the purge of Elizabeth Flynn) to the 1954 resignation of the anti-communist leaders is considered by many to be an era in which the ACLU abandoned its core principles. + +McCarthyism declined in late 1954 after television journalist Edward R. Murrow and others publicly chastised McCarthy. The controversies over the Bill of Rights that the Cold War generated ushered in a new era in American Civil liberties. In 1954, in Brown v. Board of Education, the Supreme Court unanimously overturned state-sanctioned school segregation, and after that, a flood of civil rights victories dominated the legal landscape. + +The Supreme Court handed the ACLU two key victories in 1957, in Watkins v. United States and Yates v. United States, both of which undermined the Smith Act and marked the beginning of the end of communist party membership inquiries. In 1965, the Supreme Court produced some decisions, including Lamont v. Postmaster General (in which the plaintiff was Corliss Lamont, a former ACLU board member), which upheld fifth amendment protections and brought an end to restrictions on political activity. + +1960s +The decade from 1954 to 1964 was the most successful period in the ACLU's history. Membership rose from 30,000 to 80,000, and by 1965 it had affiliates in seventeen states. During the ACLU's bi-annual conference in Colorado in 1964, the Supreme Court issued rulings on eight cases involving the ACLU; the ACLU prevailed on seven of the eight. The ACLU played a role in Supreme Court decisions reducing censorship of literature and arts, protecting freedom of association, prohibiting racial segregation, excluding religion from public schools, and providing due process protection to criminal suspects. The ACLU's success arose from changing public attitudes; the American populace was more educated, tolerant, and willing to accept unorthodox behavior. + +Separation of church and state + +Legal battles concerning the separation of church and state originated in laws dating to 1938, which required religious instruction in school or provided state funding for religious schools. The Catholic church was a leading proponent of such laws, and the primary opponents (the "separationists") were the ACLU, Americans United for Separation of Church and State, and the American Jewish Congress. The ACLU led the challenge in the 1947 Everson v. Board of Education case, in which Justice Hugo Black wrote "[t]he First Amendment has erected a wall between church and state.... That wall must be kept high and impregnable." It was not clear that the Bill of Rights forbid state governments from supporting religious education, and strong legal arguments were made by religious proponents, arguing that the Supreme Court should not act as a "national school board", and that the Constitution did not govern social issues. However, the ACLU and other advocates of church/state separation persuaded the Court to declare such activities unconstitutional. Historian Samuel Walker writes that the ACLU's "greatest impact on American life" was its role in persuading the Supreme Court to "constitutionalize" so many public controversies. + +In 1948, the ACLU prevailed in the McCollum v. Board of Education case, which challenged public school religious classes taught by clergy paid for by private funds. The ACLU also won cases challenging schools in New Mexico that were taught by clergy and had crucifixes hanging in the classrooms. In the 1960s, the ACLU, in response to member insistence, turned its attention to the in-class promotion of religion. In 1960, 42 percent of American schools included Bible reading. In 1962, the ACLU published a policy statement condemning in-school prayers, observation of religious holidays, and Bible reading. The Supreme Court concurred with the ACLU's position when it prohibited New York's in-school prayers in the 1962 Engel v. Vitale decision. Religious factions across the country rebelled against the anti-prayer decisions, leading them to propose the School Prayer Constitutional Amendment, which declared in-school prayer legal. The ACLU participated in a lobbying effort against the amendment, and the 1966 congressional vote failed to obtain the required two-thirds majority. + +However, not all cases were victories; ACLU lost cases in 1949 and 1961 which challenged state laws requiring commercial businesses to close on Sunday, the Christian Sabbath. The Supreme Court has never overturned such laws, although some states subsequently revoked many of the laws under pressure from commercial interests. + +Freedom of expression +During the 1940s and 1950s, the ACLU continued its battle against censorship of art and literature. In 1948, the New York affiliate of the ACLU received mixed results from the Supreme Court, winning the appeal of Carl Jacob Kunz, who was convicted for speaking without a police permit, but losing the appeal of Irving Feiner who was arrested to prevent a breach of the peace, based on his oration denouncing President Truman and the American Legion. The ACLU lost the case of Joseph Beauharnais, who was arrested for group libel when he distributed literature impugning the character of African Americans. + +Cities across America routinely banned movies because they were deemed to be "harmful", "offensive", or "immoral"censorship which was validated by the 1915 Mutual v. Ohio Supreme Court decision which held movies to be mere commerce, undeserving of first amendment protection. The film The Miracle was banned in New York in 1951 at the behest of the Catholic Church, but the ACLU supported the film's distributor in an appeal of the ban, and won a major victory in the 1952 decision Joseph Burstyn, Inc. v. Wilson. The Catholic Church led efforts throughout the 1950s attempting to persuade local prosecutors to ban various books and movies, leading to conflict with the ACLU when the ACLU published it statement condemning the church's tactics. Further legal actions by the ACLU successfully defended films such as M and la Ronde, leading the eventual dismantling of movie censorship. Hollywood continued employing self-censorship with its own Production Code, but in 1956 the ACLU called on Hollywood to abolish the Code. + +The ACLU defended beat generation artists, including Allen Ginsberg who was prosecuted for his poem "Howl"; andin an unorthodox case the ACLU helped a coffee house regain its restaurant license which was revoked because its Beat customers were allegedly disturbing the peace of the neighborhood. + +The ACLU lost an important press censorship case when, in 1957, the Supreme Court upheld the obscenity conviction of publisher Samuel Roth for distributing adult magazines. As late as 1953, books such as Tropic of Cancer and From Here to Eternity were still banned. But public standards rapidly became more liberal through the 1960s, and obscenity was notoriously difficult to define, so by 1971, obscenity prosecutions had halted. + +Racial discrimination +A major aspect of civil liberties progress after World War II was the undoing centuries of racism in federal, state, and local governments an effort generally associated with the civil rights movement. Several civil liberties organizations worked together for progress, including the National Association for the Advancement of Colored People (NAACP), the ACLU, and the American Jewish Congress. The NAACP took primary responsibility for Supreme Court cases (often led by lead NAACP attorney Thurgood Marshall), with the ACLU focusing on police misconduct, and supporting the NAACP with amicus briefs. The NAACP achieved a key victory in 1950 with the Henderson v. United States decision that ended segregation in interstate bus and rail transportation. + +In 1954, the ACLU filed an amicus brief in the case of Brown v. Board of Education, which led to the ban on racial segregation in US public schools. Southern states instituted a McCarthyism-style witch-hunt against the NAACP, attempting to force it to disclose membership lists. The ACLU's fight against racism was not limited to segregation; in 1964, the ACLU provided key support to plaintiffs, primarily lower-income urban residents, in Reynolds v. Sims, which required states to establish the voting districts following the "one person, one vote" principle. + +Police misconduct +The ACLU regularly tackled police misconduct issues, starting with the 1932 case Powell v. Alabama (right to an attorney), and including 1942's Betts v. Brady (right to an attorney), and 1951's Rochin v. California (involuntary stomach pumping). In the late 1940s, several ACLU local affiliates established permanent committees to address policing issues. During the 1950s and 1960s, the ACLU was responsible for substantially advancing the legal protections against police misconduct. In 1958, the Philadelphia affiliate was responsible for causing the City of Philadelphia to create the nation's first civilian police review board. In 1959, the Illinois affiliate published the first report in the nation, Secret Detention by the Chicago Police which documented unlawful detention by police. + +Some of the most notable ACLU successes came in the 1960s when the ACLU prevailed in a string of cases limiting the power of police to gather evidence; in 1961's Mapp v. Ohio, the Supreme court required states to obtain a warrant before searching a person's home. The Gideon v. Wainwright decision in 1963 provided legal representation to indigents. In 1964, the ACLU persuaded the Court, in Escobedo v. Illinois, to permit suspects to have an attorney present during questioning. And, in 1966, Miranda v. Arizona federal decision required police to notify suspects of their constitutional rights, which was later extended to juveniles in the following year's in re Gault (1967) federal ruling. Although many law enforcement officials criticized the ACLU for expanding the rights of suspects, police officers also used the services of the ACLU. For example, when the ACLU represented New York City policemen in their lawsuit, which objected to searches of their workplace lockers. In the late 1960s, civilian review boards in New York City and Philadelphia were abolished, over the ACLU's objection. + +Civil liberties revolution of the 1960s +The 1960s was a tumultuous era in the United States, and public interest in civil liberties underwent explosive growth. Civil liberties actions in the 1960s were often led by young people and often employed tactics such as sit ins and marches. Protests were often peaceful but sometimes employed militant tactics. The ACLU played a central role in all major civil liberties debates of the 1960s, including new fields such as gay rights, prisoner's rights, abortion, rights of the poor, and the death penalty. Membership in the ACLU increased from 52,000 at the beginning of the decade to 104,000 in 1970. In 1960, there were affiliates in seven states, and by 1974 there were affiliates in 46 states. During the 1960s, the ACLU underwent a major transformation in tactics; it shifted emphasis from legal appeals (generally involving amicus briefs submitted to the Supreme Court) to direct representation of defendants when they were initially arrested. At the same time, the ACLU transformed its style from "disengaged and elitist" to "emotionally engaged". The ACLU published a breakthrough document in 1963, titled How Americans Protest, which was borne of frustration with the slow progress in battling racism, and which endorsed aggressive, even militant protest techniques. + +African-American protests in the South accelerated in the early 1960s, and the ACLU assisted at every step. After four African-American college students staged a sit-in in a segregated North Carolina department store, the sit-in movement gained momentum across the United States. During 1960–61, the ACLU defended black students arrested for demonstrating in North Carolina, Florida, and Louisiana. The ACLU also provided legal help for the Freedom Rides in 1961, the integration of the University of Mississippi, the Birmingham campaign in 1963, and the 1964 Freedom Summer. + +The NAACP was responsible for managing most sit-in related cases that made it to the Supreme Court, winning nearly every decision. But it fell to the ACLU and other legal volunteer efforts to provide legal representation to hundreds of protestorswhite and blackwho were arrested while protesting in the South. The ACLU joined with other civil liberties groups to form the Lawyers Constitutional Defense Committee (LCDC), which provided legal representation to many protesters. The ACLU provided the majority of the funding for the LCDC. + +In 1964, the ACLU opened up a major office in Atlanta, Georgia, dedicated to serving Southern issues. Much of the ACLU's progress in the South was due to Charles Morgan Jr., the charismatic leader of the Atlanta office. Morgan was responsible for desegregating juries (Whitus v. Georgia), desegregating prisons (Lee v. Washington), and reforming election laws. In 1966, the southern office successfully represented African-American congressman Julian Bond in Bond v. Floyd, after the Georgia House of Representatives refused to admit Bond into the legislature on the basis that he was an admitted pacifist opposed to the ongoing Vietnam War. Another widely publicized case defended by Morgan was that of Army doctor Howard Levy, who was convicted of refusing to train Green Berets. Despite raising the defense that the Green Berets were committing war crimes in Vietnam, Levy lost on appeal in Parker v. Levy, 417 US 733 (1974). + +In 1969, the ACLU won a significant victory for free speech when it defended Dick Gregory after he was arrested for peacefully protesting against the mayor of Chicago. The court ruled in Gregory v. Chicago that a speaker cannot be arrested for disturbing the peace when hostility is initiated by someone in the audience, as that would amount to a "heckler's veto". + +Vietnam War +The ACLU was at the center of several legal aspects of the Vietnam war: defending draft resisters, challenging the constitutionality of the war, the potential impeachment of Richard Nixon, and the use of national security concerns to preemptively censor newspapers. + +David J. Miller was the first person prosecuted for burning his draft card. The New York affiliate of the ACLU appealed his 1965 conviction (367 F.2d 72: United States of America v. David J. Miller, 1966), but the Supreme Court refused to hear the appeal. Two years later, the Massachusetts affiliate took the card-burning case of David O'Brien to the Supreme Court, arguing that the act of burning was a form of symbolic speech, but the Supreme Court upheld the conviction in United States v. O'Brien, 391 US 367 (1968). Thirteen-year-old Junior High student Mary Tinker wore a black armband to school in 1965 to object to the war and was suspended from school. The ACLU appealed her case to the Supreme Court and won a victory in Tinker v. Des Moines Independent Community School District. This critical case established that the government may not establish "enclaves" such as schools or prisons where all rights are forfeited. + +The ACLU defended Sydney Street, who was arrested for burning an American flag to protest the reported assassination of civil rights leader James Meredith. In the Street v. New York decision, the court agreed with the ACLU that encouraging the country to abandon one of its national symbols was a constitutionally protected form of expression. The ACLU successfully defended Paul Cohen, who was arrested for wearing a jacket with the words "fuck the draft" on its back while he walked through the Los Angeles courthouse. The Supreme Court, in Cohen v. California, held that the vulgarity of the wording was essential to convey the intensity of the message. + +Non-war-related free speech rights were also advanced during the Vietnam war era; in 1969, the ACLU defended a Ku Klux Klan member who advocated long-term violence against the government, and the Supreme Court concurred with the ACLU's argument in the landmark decision Brandenburg v. Ohio, which held that only speech which advocated imminent violence could be outlawed. + +A major crisis gripped the ACLU in 1968 when a debate erupted over whether to defend Benjamin Spock and the Boston Five against federal charges that they encouraged draftees to avoid the draft. The ACLU board was deeply split over whether to defend the activists; half the board harbored anti-war sentiments and felt that the ACLU should lend its resources to the cause of the Boston Five. The other half of the board believed that civil liberties were not at stake and the ACLU would be taking a political stance. Behind the debate was the longstanding ACLU tradition that it was politically impartial and provided legal advice without regard to the defendants' political views. The board finally agreed to a compromise solution that permitted the ACLU to defend the anti-war activists without endorsing the activist's political views. Some critics of the ACLU suggest that the ACLU became a partisan political organization following the Spock case. After the Kent State shootings in 1970, ACLU leaders took another step toward politics by passing a resolution condemning the Vietnam War. The resolution was based on various legal arguments, including civil liberties violations and claiming that the war was illegal. + +Also in 1968, the ACLU held an internal symposium to discuss its dual roles: providing "direct" legal support (defense for accused in their initial trial, benefiting only the individual defendant) and appellate support (providing amicus briefs during the appeal process, to establish widespread legal precedent). Historically, the ACLU was known for its appellate work, which led to landmark Supreme Court decisions, but by 1968, 90% of the ACLU's legal activities involved direct representation. The symposium concluded that both roles were valid for the ACLU. + +1970s and 1980s + +Watergate era + +The ACLU supported The New York Times in its 1971 suit against the government, requesting permission to publish the Pentagon Papers. The court upheld the Times and ACLU in the New York Times Co. v. United States ruling, which held that the government could not preemptively prohibit the publication of classified information and had to wait until after it was published to take action. + +On September 30, 1973, the ACLU became first national organization to publicly call for the impeachment and removal from office of President Richard Nixon. Six civil liberties violations were cited as grounds: "specific proved violations of the rights of political dissent; usurpation of Congressional war‐making powers; establishment of a personal secret police which committed crimes; attempted interference in the trial of Daniel Ellsberg; distortion of the system of justice and perversion of other Federal agencies". One month later, after the House of Representatives began an impeachment inquiry against him, the organization released a 56‐page handbook detailing "17 things citizens could do to bring about the impeachment of President Nixon". This resolution, when placed beside the earlier resolution opposing the Vietnam war, convinced many ACLU critics, particularly conservatives, that the organization had transformed into a liberal political organization. + +Enclaves and new civil liberties +The decade from 1965 to 1975 saw an expansion of civil liberties. Administratively, the ACLU responded by appointing Aryeh Neier to take over from Pemberton as executive director in 1970. Neier embarked on an ambitious program to expand the ACLU; he created the ACLU Foundation to raise funds and created several new programs to focus the ACLU's legal efforts. By 1974, ACLU membership had reached 275,000. + +During those years, the ACLU worked to expand legal rights in three directions: new rights for persons within government-run "enclaves", new rights for members of what it called "victim groups", and privacy rights for citizens in general. At the same time, the organization grew substantially. The ACLU helped develop the field of constitutional law that governs "enclaves", which are groups of persons that live in conditions under government control. Enclaves include mental hospital patients, military members, prisoners, and students (while at school). The term enclave originated with Supreme Court justice Abe Fortas's use of the phrase "schools may not be enclaves of totalitarianism" in the Tinker v. Des Moines decision. + +The ACLU initiated the legal field of student's rights with the Tinker v. Des Moines case and expanded it with cases such as Goss v. Lopez, which required schools to provide students an opportunity to appeal suspensions. + +As early as 1945, the ACLU had taken a stand to protect the rights of the mentally ill when it drafted a model statute governing mental commitments. In the 1960s, the ACLU opposed involuntary commitments unless it could be demonstrated that the person was a danger to himself or the community. In the landmark 1975 O'Connor v. Donaldson decision, the ACLU represented a non-violent mental health patient who had been confined against his will for 15 years and persuaded the Supreme Court to rule such involuntary confinements illegal. The ACLU has also defended the rights of mentally ill individuals who are not dangerous but create disturbances. The New York chapter of the ACLU defended Billie Boggs, a woman with mental illness who exposed herself and defecated and urinated in public. + +Before 1960, prisoners had virtually no recourse to the court system because courts considered prisoners to have no civil rights. That changed in the late 1950s, when the ACLU began representing prisoners subject to police brutality or deprived of religious reading material. In 1968, the ACLU successfully sued to desegregate the Alabama prison system; in 1969, the New York affiliate adopted a project to represent prisoners in New York prisons. Private attorney Phil Hirschkop discovered degrading conditions in Virginia prisons following the Virginia State Penitentiary strike and won an important victory in 1971's Landman v. Royster which prohibited Virginia from treating prisoners in inhumane ways. In 1972, the ACLU consolidated several prison rights efforts across the nation and created the National Prison Project. The ACLU's efforts led to landmark cases such as Ruiz v. Estelle (requiring reform of the Texas prison system), and in 1996 US Congress enacted the Prison Litigation Reform Act (PLRA) which codified prisoners' rights. + +Victim groups + +During the 1960s and 1970s, the ACLU expanded its scope to include what it referred to as "victim groups", namely women, the poor, and homosexuals. Heeding the call of female members, the ACLU endorsed the Equal Rights Amendment in 1970 and created the Women's Rights Project in 1971. The Women's Rights Project dominated the legal field, handling more than twice as many cases as the National Organization for Women, including breakthrough cases such as Reed v. Reed, Frontiero v. Richardson, and Taylor v. Louisiana. + +ACLU leader Harriet Pilpel raised the issue of the rights of homosexuals in 1964, and two years later, the ACLU formally endorsed gay rights. In 1972, ACLU cooperating attorneys in Oregon filed the first federal civil rights case involving a claim of unconstitutional discrimination against a gay or lesbian public school teacher. The US District Court held that a state statute that authorized school districts to fire teachers for "immorality" was unconstitutionally vague, and awarded monetary damages to the teacher. The court refused to reinstate the teacher, and the Ninth Circuit Court of Appeals affirmed that refusal by a 2-to-1 vote. Burton v. Cascade School District, 353 F. Supp. 254 (D. Or. 1972), aff'd 512 F.2d 850 (1975). In 1973, the ACLU created the Sexual Privacy Project (later the Gay and Lesbian Rights Project), which combated discrimination against homosexuals. This support continued into the 2000s. For example, after then-Senator Larry Craig was arrested for soliciting sex in a public restroom in 2007, the ACLU wrote an amicus brief for Craig, saying that sex between consenting adults in public places was protected under privacy rights. + +The rights of the poor were another area that the ACLU expanded. In 1966 and again in 1968, activists within the ACLU encouraged the organization to adopt a policy overhauling the welfare system and guaranteeing low-income families a baseline income; but the ACLU board did not approve the proposals. However, the ACLU played a key role in the 1968 King v. Smith decision, where the Supreme Court ruled that welfare benefits for children could not be denied by a state simply because the mother cohabited with a boyfriend. + +Reproductive Freedom Project +The ACLU founded the Reproductive Freedom Project in 1974 to defend individuals the government obstructs in cases involving access to abortions, birth control, or sexual education. According to its mission statement, the project works to provide access to reproductive health care for individuals. The project also opposes abstinence-only sex education, arguing that it promotes an unwillingness to use contraceptives. + +In 1980, the Project filed Poe v. Lynchburg Training School & Hospital which attempted to overturn Buck v. Bell, the 1927 US Supreme Court decision which had allowed the Commonwealth of Virginia to legally sterilize persons it deemed to be mentally defective without their permission. Though the Court did not overturn Buck v.Bell, in 1985, the state agreed to provide counseling and medical treatment to the survivors among the 7,200 to 8,300 people sterilized between 1927 and 1979. In 1977, the ACLU took part in and litigated Walker v. Pierce, the federal circuit court case that led to federal regulations to prevent Medicaid patients from being sterilized without their knowledge or consent. In 1981–1990, the Project litigated Hodgson v. Minnesota, which resulted in the Supreme Court overturning a state law requiring both parents to be notified before a minor could legally have an abortion. In the 1990s, the Project provided legal assistance and resource kits to those who were being challenged for educating about sexuality and AIDS. In 1995, the Project filed an amicus brief in Curtis v. School Committee of Falmouth, which allowed for the distribution of condoms in a public school. + +The Reproductive Freedom Project focuses on three ideas: (1) to "reverse the shortage of trained abortion providers throughout the country" (2) to "block state and federal welfare "reform" proposals that cut off benefits for children who are born to women already receiving welfare, unmarried women, or teenagers" and (3) to "stop the elimination of vital reproductive health services as a result of hospital mergers and health care networks". The Project proposes to achieve these goals through legal action and litigation. + +Privacy +The right to privacy is not explicitly identified in the US Constitution, but the ACLU led the charge to establish such rights in the indecisive Poe v. Ullman (1961) case, which addressed a state statute outlawing contraception. The issue arose again in Griswold v. Connecticut (1965), and this time the Supreme Court adopted the ACLU's position and formally declared a right to privacy. The New York affiliate of the ACLU pushed to eliminate anti-abortion laws starting in 1964, a year before Griswold was decided; in 1967 the ACLU itself formally adopted the right to abortion as a policy. The ACLU led the defense in United States v. Vuitch (1971), which expanded the right of physicians to determine when abortions were necessary. These efforts culminated in one of the most controversial Supreme Court decisions, Roe v. Wade (1973), which legalized abortion throughout the United States. The ACLU successfully argued against state bans on interracial marriage, in the case of Loving v. Virginia (1967). + +Related to privacy, the ACLU engaged in several battles to ensure that government records about individuals were kept private and to give individuals the right to review their records. The ACLU supported several measures, including the 1970 Fair Credit Reporting Act, which required credit agencies to divulge credit information to individuals; the 1973 Family Educational Rights and Privacy Act, which provided students the right to access their records; and the 1974 Privacy Act, which prevented the federal government from disclosing personal information without good cause. + +Allegations of bias +In the early 1970s, conservatives and libertarians began to criticize the ACLU for being too political and too liberal. Legal scholar Joseph W. Bishop wrote that the ACLU's trend to partisanship started with its defense of Spock's anti-war protests. Critics also blamed the ACLU for encouraging the Supreme Court to embrace judicial activism. Critics claimed that the ACLU's support of controversial decisions like Roe v. Wade and Griswold v. Connecticut violated the intention of the authors of the Bill of Rights. The ACLU became an issue in the 1988 presidential campaign, when Republican candidate George H. W. Bush accused Democratic candidate Michael Dukakis (a member of the ACLU) of being a "card carrying member of the ACLU". + +The Skokie case + +In 1977, the National Socialist Party of America, led by Frank Collin, applied to the town of Skokie, Illinois, for a permit to hold a demonstration in the town park. Skokie at the time had a majority population of Jews, totaling 40,000 of 70,000 citizens, some of whom were survivors of Nazi concentration camps. Skokie refused to grant the NSPA a permit and passed ordinances against hate speech and military wear, in addition to requiring an insurance bond. Skokie's Village Council ordered village attorney, Harvey Schwartz, to seek an injunction to stop the demonstration. The ACLU assisted Collin and appealed to federal court, eventually prevailing in NSPA v. Village of Skokie + +The Skokie case was heavily publicized across America, partially because Jewish groups such as the Jewish Defense League and Anti Defamation League strenuously objected to the demonstration, leading many members of the ACLU to cancel their memberships. The Illinois affiliate of the ACLU lost about 25% of its membership and nearly one-third of its budget. The financial strain from the controversy led to layoffs at local chapters. After the membership crisis died down, the ACLU sent out a fund-raising appeal which explained their rationale for the Skokie case and raised over $500,000 ($ in dollars). + +Reagan era + +The inauguration of Ronald Reagan as president in 1981 ushered in an eight-year period of conservative leadership in the US government. Under Reagan's leadership, the government pushed a conservative social agenda. + +Fifty years after the Scopes trial, the ACLU found itself fighting another classroom case, the Arkansas 1981 creationism statute, which required schools to teach the biblical account of creation as a scientific alternative to evolution. The ACLU won the case in the McLean v. Arkansas decision. + +In 1982, the ACLU became involved in a case involving the distribution of child pornography (New York v. Ferber). In an amicus brief, the ACLU argued that child pornography that violates the three prong obscenity test should be outlawed. However, the law was overly restrictive because it banned artistic displays and non-obscene material. The court did not adopt the ACLU's position. + +During the 1988 presidential election, Vice President George H. W. Bush noted that his opponent Massachusetts Governor Michael Dukakis had described himself as a "card-carrying member of the ACLU" and used that as evidence that Dukakis was "a strong, passionate liberal" and "out of the mainstream". The phrase subsequently was used by the organization in an advertising campaign. + +1990s + +In 1990, the ACLU defended Lieutenant Colonel Oliver North, whose conviction was tainted by coerced testimonya violation of his Fifth Amendment rightsduring the Iran–Contra affair, where Oliver North was involved in illegal weapons sales to Iran to illegally fund the Contra guerillas. + +In 1997, ruling unanimously in the case of Reno v. American Civil Liberties Union, the Supreme Court voided the anti-indecency provisions of the Communications Decency Act (the CDA), finding they violated the freedom of speech provisions of the First Amendment. In their decision, the Supreme Court held that the CDA's "use of the undefined terms 'indecent' and 'patently offensive' will provoke uncertainty among speakers about how the two standards relate to each other and just what they mean." +In 2000, Marvin Johnson, a legislative counsel for the ACLU, stated that proposed anti-spam legislation infringed on free speech by denying anonymity and by forcing spam to be labeled as such, "Standardized labeling is compelled speech." He also stated, "It's relatively simple to click and delete." The debate found the ACLU joining with the Direct Marketing Association and the Center for Democracy and Technology in 2000 in criticizing a bipartisan bill in the House of Representatives. As early as 1997, the ACLU had taken a strong position that nearly all spam legislation was improper, although it has supported "opt-out" requirements in some cases. The ACLU opposed the 2003 CAN-SPAM act suggesting that it could have a chilling effect on speech in cyberspace. It has been criticized for this position. + +In November 2000, 15 African-American residents of Hearne, Texas, were indicted on drug charges after being arrested in a series of "drug sweeps". The ACLU filed a class-action lawsuit, Kelly v. Paschall, on their behalf, alleging that the arrests were unlawful. The ACLU contended that 15 percent of Hearne's male African-American population aged 18 to 34 were arrested based only on the "uncorroborated word of a single unreliable confidential informant coerced by police to make cases". On May 11, 2005, the ACLU and Robertson County announced a confidential settlement of the lawsuit, an outcome which "both sides stated that they were satisfied with". The District Attorney dismissed the charges against the plaintiffs of the suit. The 2009 film American Violet depicts this case. + +In 2000, the ACLU's Massachusetts affiliate represented the North American Man Boy Love Association (NAMBLA), on first amendment grounds, in the Curley v. NAMBLA wrongful death civil suit. The organization was sued because a man who raped and murdered a child had visited the NAMBLA website. Also in 2000, the ACLU lost the Boy Scouts of America v. Dale case, which had asked the Supreme Court to require the Boy Scouts of America to drop their policy of prohibiting homosexuals from becoming Boy Scout leaders. + +21st century + +Free speech +In 2006, the ACLU of Washington State joined with a pro-gun rights organization, the Second Amendment Foundation, and prevailed in a lawsuit against the North Central Regional Library District (NCRL) in Washington for its policy of refusing to disable restrictions upon an adult patron's request. Library patrons attempting to access pro-gun web sites were blocked, and the library refused to remove the blocks. In 2012, the ACLU sued the same library system for refusing to disable temporarily, at the request of an adult patron, Internet filters which blocked access to Google Images. + +In 2006, the ACLU challenged a Missouri law prohibiting picketing outside veterans' funerals. The suit was filed in support of the Westboro Baptist Church and Shirley Phelps-Roper, who were threatened with arrest. The Westboro Baptist Church is well known for its picket signs that contain messages such as "God Hates Fags", "Thank God for Dead Soldiers", and "Thank God for 9/11". The ACLU issued a statement calling the legislation a "law that infringes on Shirley Phelps-Roper's rights to religious liberty and free speech". The ACLU prevailed in the lawsuit. + +The ACLU argued in an amicus brief to the Supreme Court that a decision on the constitutionality of Massachusetts law required the consideration of additional evidence because lower courts have undervalued the right to engage in sidewalk counseling. The law prohibited sidewalk counselors from approaching women outside abortion facilities and offering them alternatives to abortion but allowed escorts to speak with them and accompany them into the building. In overturning the law in McCullen v. Coakley, the Supreme Court unanimously ruled that it violated the counselors' freedom of speech and that it was viewpoint discrimination. + +In 2009, the ACLU filed an amicus brief in Citizens United v. FEC, arguing that the Bipartisan Campaign Reform Act of 2002 violated the First Amendment right to free speech by curtailing political speech. This stance on the landmark Citizens United case caused considerable disagreement within the organization, resulting in a discussion about its future stance during a quarterly board meeting in 2010. On March 27, 2012, the ACLU reaffirmed its stance in support of the Supreme Court's Citizens United ruling, at the same time voicing support for expanded public financing of election campaigns and stating the organization would firmly oppose any future constitutional amendment limiting free speech. + +In 2012, the ACLU filed suit on behalf of the Ku Klux Klan of Georgia, claiming that the KKK was unfairly rejected from the state's "Adopt-a-Highway" program. The ACLU prevailed in the lawsuit. + +Waning interest in defending white supremacists' first amendment rights + +Beginning in 2017, some individuals claimed the ACLU was reducing its support of unpopular free speech (specifically by declining to defend speech made by conservatives) in favor of identity politics, political correctness, and progressivism. Former ACLU director Ira Glasser stated that "the ACLU might not take the Skokie case today." In the 2020 documentary Mighty Ira, which chronicles Glasser's life and career at the ACLU, Glasser says he would defend the ACLU's decision to take the Skokie case again today if needed. + +One basis of these allegations was a 2017 statement made by the ACLU president to a reporter after the death of a counter-protester during the 2017 Unite the Right rally in Virginia, where Romero told a reporter that the ACLU would no longer support legal cases of activists that wish to carry guns at their protests. + +Another basis for these claims was an internal ACLU memo dated June 2018, discussing factors to evaluate when deciding whether or not to take a case. The memo listed several factors to consider, including "the extent to which the speech may assist in advancing the goals of white supremacists or others whose views are contrary to our values". Some analysts viewed this as a retreat from the ACLU's historically strong support of first amendment rights, regardless of whether minorities were negatively impacted by the speech, citing the ACLU's past support for certain KKK and Nazi legal cases. The memo's authors stated that the memo did not define a change in official ACLU policy, but was intended as a guideline to assist ACLU affiliates in deciding which cases to take. In 2021, the ACLU responded to the criticisms by denying that they are reducing their support for unpopular First Amendment causes and listing 27 cases from 2017 to 2021 where the ACLU supported a party holding an unpopular or repugnant viewpoint. The cases included one which challenged college restrictions on hate speech; a case defending a Catholic school's right to discriminate in hiring; and a case that defended antisemitic protesters who marched outside a synagogue. + +LGBTQ issues +In March 2004, the ACLU, along with Lambda Legal and the National Center for Lesbian Rights, sued the state of California on behalf of six same-sex couples who were denied marriage licenses. That case, Woo v. Lockyer, was eventually consolidated into In re Marriage Cases, the California Supreme Court case which led to same-sex marriage being available in that state from June 16, 2008, until Proposition 8 was passed on November 4, 2008. The ACLU, Lambda Legal and the National Center for Lesbian Rights then challenged Proposition 8 and won. + +In 2010, the ACLU of Illinois was inducted into the Chicago Gay and Lesbian Hall of Fame as a Friend of the Community. + +In 2011, the ACLU started its Don't Filter Me project, countering LGBT-related Internet censorship in public schools in the United States. + +On January 7, 2013, the ACLU settled with the federal government in Collins v. United States that provided for the payment of full separation pay to servicemembers discharged under "don't ask, don't tell" since November 10, 2004, who had previously been granted only half that. Some 181 were expected to receive about $13,000 each. + +In 2021, the ACLU tweeted a quote by Ruth Bader Ginsburg on the subject of pregnancy, replacing gender-specific words with bracketed gender-neutral words. The president of the ACLU later apologized for the changes to the quote, explaining that it was a good-faith mistake by the ACLU's media team, attempting to address the fact that there are people who seek abortions who do not identify as women. + +In 2021, the ACLU filed a brief siding with a school district that had a policy of using preferred pronouns for transgender students. Some analysts felt this was a retreat from the ACLU's historical defense of the first amendment because the ACLU was opposing the teachers who were disciplined for refusing to use the preferred pronouns. + +Second amendment +In light of the Supreme Court's Heller decision recognizing that the Constitution protects an individual right to bear arms, ACLU of Nevada took a position of supporting "the individual's right to bear arms subject to constitutionally permissible regulations" and pledged to "defend this right as it defends other constitutional rights". In 2021, the ACLU supported the position that the Second Amendment was originally written to ensure that Southern states could use militias to suppress slave uprisings, and that anti-Blackness ensured its inclusion in the Bill of Rights. + +Anti-terrorism issues + +After the September 11 attacks, the federal government instituted a broad range of new measures to combat terrorism, including the passage of the Patriot Act. The ACLU challenged many of the measures, claiming that they violated rights regarding due process, privacy, illegal searches, and cruel and unusual punishment. An ACLU policy statement states: + +During the ensuing debate regarding the proper balance of civil liberties and security, the membership of the ACLU increased by 20%, bringing the group's total enrollment to 330,000. The growth continued, and by August 2008 ACLU membership was greater than 500,000. It remained at that level through 2011. + +The ACLU has been a vocal opponent of the Patriot Act of 2001, the PATRIOT 2 Act of 2003, and associated legislation made in response to the threat of domestic terrorism. In response to a requirement of the USA PATRIOT Act, the ACLU withdrew from the Combined Federal Campaign charity drive. The campaign required ACLU employees to be checked against a federal anti-terrorism watch list. The ACLU has stated that it would "reject $500,000 in contributions from private individuals rather than submit to a government 'blacklist' policy". + +In 2004, the ACLU sued the federal government in American Civil Liberties Union v. Ashcroft on behalf of Nicholas Merrill, owner of an Internet service provider. Under the provisions of the Patriot Act, the government had issued national security letters to Merrill to compel him to provide private Internet access information from some of his customers. In addition, the government placed a gag order on Merrill, forbidding him from discussing the matter with anyone. + +In January 2006, the ACLU filed a lawsuit, ACLU v. NSA, in a federal district court in Michigan, challenging government spying in the NSA warrantless surveillance controversy. On August 17, 2006, that court ruled that the warrantless wiretapping program was unconstitutional and ordered it ended immediately. However, the order was stayed pending an appeal. The Bush administration did suspend the program while the appeal was being heard. In February 2008, the US Supreme Court turned down an appeal from the ACLU to let it pursue a lawsuit against the program that began shortly after the September 11 terror attacks. + +The ACLU and other organizations also filed separate lawsuits against telecommunications companies. The ACLU filed a lawsuit in Illinois (Terkel v. AT&T), which was dismissed because of the state secrets privilege and two others in California requesting injunctions against AT&T and Verizon. On August 10, 2006, the lawsuits against the telecommunications companies were transferred to a federal judge in San Francisco. + +The ACLU represents a Muslim-American who was detained but never accused of a crime in Ashcroft v. al-Kidd, a civil suit against former Attorney General John Ashcroft. In January 2010, the American military released the names of 645 detainees held at the Bagram Theater Internment Facility in Afghanistan, modifying its long-held position against publicizing such information. This list was prompted by a Freedom of Information Act lawsuit filed in September 2009 by the ACLU, whose lawyers had also requested detailed information about conditions, rules, and regulations. + +The ACLU has also criticized targeted killings of American citizens who fight against the United States. In 2011, the ACLU criticized the killing of radical Muslim cleric Anwar al-Awlaki on the basis that it was a violation of his Fifth Amendment right not to be deprived of life, liberty, or property without due process of law. + +On August 10, 2020, in an opinion article for USA Today by Anthony D. Romero, the ACLU called for the dismantling of the United States Department of Homeland Security over the deployment of federal forces in July 2020 during the George Floyd protests. On August 26, 2020, the ACLU filed a lawsuit on behalf of seven protesters and three veterans following the protests in Portland, Oregon, which accused the Trump Administration of using excessive force and unlawful arrests with federal officers. + +Trump administration + +Following Donald Trump's election as president on November 8, 2016, the ACLU responded on Twitter by saying: "Should President-elect Donald Trump attempt to implement his unconstitutional campaign promises, we'll see him in court." On January 27, 2017, President Trump signed an executive order indefinitely barring "Syrian refugees from entering the United States, suspended all refugee admissions for 120 days and blocked citizens of seven Muslim-majority countries, refugees or otherwise, from entering the United States for 90 days: Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen". The ACLU responded by filing a lawsuit against the ban on behalf of Hameed Khalid Darweesh and Haider Sameer Abdulkhaleq Alshawi, who had been detained at JFK International Airport. On January 28, 2017, District Court Judge Ann Donnelly granted a temporary injunction against the immigration order, saying it was difficult to see any harm from allowing the newly arrived immigrants to remain in the country. + +In response to Trump's order, the ACLU raised more than $24 million from more than 350,000 individual online donations in two days. This amounted to six times what the ACLU normally receives in online donations in a year. Celebrities donating included Chris Sacca (who offered to match other people's donations and ultimately gave $150,000), Rosie O'Donnell, Judd Apatow, Sia, John Legend, and Adele. The number of members of the ACLU doubled in the time from the election to end of January to 1 million. + +Grants and contributions increased from US$106,628,381 reported by the 2016 year-end income statement to $274,104,575 by the 2017 year-end statement. The segment's primary revenue source came from individual contributions in response to the Trump presidency's infringements on civil liberties. The surge in donations more than doubled the total support and revenue of the non-profit organization year over year from 2016 to 2017. Besides filing more lawsuits than during previous presidential administrations, the ACLU has spent more money on advertisements and messaging as well, weighing in on elections and pressing political concerns. This increased public profile has drawn some accusations that the organization has become more politically partisan than in previous decades. + +Miscellaneous + +During the 2004 trial regarding allegations of Rush Limbaugh's drug abuse, the ACLU argued that his privacy should not have been compromised by allowing law enforcement examination of his medical records. + +In June 2004, the school district in Dover, Pennsylvania, required that its high school biology students listen to a statement that asserted that the theory of evolution is not fact and mentioning intelligent design as an alternative theory. Several parents called the ACLU to complain because they believed that the school was promoting a religious idea in the classroom and violating the Establishment Clause of the First Amendment. The ACLU, joined by Americans United for Separation of Church and State, represented the parents in a lawsuit against the school district. After a lengthy trial, Judge John E. Jones III ruled in favor of the parents in the Kitzmiller v. Dover Area School District decision, finding that intelligent design is not science and permanently forbidding the Dover school system from teaching intelligent design in science classes. + +In April 2006, Edward Jones and the ACLU sued the City of Los Angeles, on behalf of Robert Lee Purrie and five other homeless people, for the city's violation of the 8th and 14th Amendments to the US Constitution, and Article I, sections 7 and 17 of the California Constitution (supporting due process and equal protection, and prohibiting cruel and unusual punishment). The Court ruled in favor of the ACLU, stating that "the LAPD cannot arrest people for sitting, lying, or sleeping on public sidewalks in Skid Row." Enforcement of section 41.18(d) 24 hours a day against persons with nowhere else to sit, lie, or sleep other than on public streets and sidewalks is breaking these amendments. The Court said the anti-camping ordinance is "one of the most restrictive municipal laws regulating public spaces in the United States". Jones and the ACLU wanted a compromise in which the LAPD is barred from enforcing section 41.18(d) (arrest, seizure, and imprisonment) in Skid Row between 9:00 p.m. and 6:30 am. The compromise plan permitted the homeless to sleep on the sidewalk, provided they were not "within 10 feet of any business or residential entrance" and only between these hours. One of the motivations for the compromise was the shortage of space in the prison system. Downtown development business interests and the Central City Association (CCA) were against the settlement. Police Chief William Bratton said the case had slowed the police effort to fight crime and clean up Skid Row and that when he was allowed to clean up Skid Row, real estate profited. On September 20, 2006, the Los Angeles City Council voted to reject the compromise. On October 3, 2006, police arrested Skid Row's transients for sleeping on the streets for the first time in months. + +In 2009, the Oregon ACLU opposed changing state law to permit teachers to wear religious clothing in classrooms, citing the separation of church and state principles. The ACLU's efforts were not successful. + +In 2018, the ACLU conceived and ghostwrote an op-ed in The Washington Post in which Amber Heard accused her ex-husband Johnny Depp of domestic abuse, leading Depp to sue Heard for defamation over the op-ed in the 2022 trial Depp v. Heard. The ACLU testified in the trial that they wrote the op-ed in exchange for a $3.5 million donation pledge from Heard, and timed its release to capitalize on the press from Heard's newly released film Aquaman. The ACLU demanded $86,000 from Depp for the cost of producing documents for the case. At the end of the trial, the jury ruled that Heard had defamed Depp with actual malice in all three counts related to the Washington Post op-ed. + +In June 2020, the ACLU sued the federal government for denying Paycheck Protection Program loans to business owners with criminal backgrounds. + +See also + + American Civil Rights Union + British Columbia Civil Liberties Association + Canadian Civil Liberties Association + Foundation for Individual Rights and Expression (FIRE) + Institute for Justice + Liberty, a British equivalent + List of court cases involving the American Civil Liberties Union + National Emergency Civil Liberties Committee + New York Civil Liberties Union + Political freedom + Southern Poverty Law Center + +Citations + +General and cited references + + Bodenhamer, David, and Ely, James, Editors (2008).

( ), formerly Adobe Systems Incorporated, is an American multinational computer software company incorporated in Delaware +and headquartered in San Jose, California. It has historically specialized in software for the creation and publication of a wide range of content, including graphics, photography, illustration, animation, multimedia/video, motion pictures, and print. Its flagship products include Adobe Photoshop image editing software; Adobe Illustrator vector-based illustration software; Adobe Acrobat Reader and the Portable Document Format (PDF); and a host of tools primarily for audio-visual content creation, editing and publishing. Adobe offered a bundled solution of its products named Adobe Creative Suite, which evolved into a subscription software as a service (SaaS) offering named Adobe Creative Cloud. The company also expanded into digital marketing software and in 2021 was considered one of the top global leaders in Customer Experience Management (CXM). + +Adobe was founded in December 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC to develop and sell the PostScript page description language. In 1985, Apple Computer licensed PostScript for use in its LaserWriter printers, which helped spark the desktop publishing revolution. Adobe later developed animation and multimedia through its acquisition of Macromedia, from which it acquired Macromedia Flash; video editing and compositing software with Adobe Premiere, later known as Adobe Premiere Pro; low-code web development with Adobe Muse; and a suite of software for digital marketing management. + +As of 2022, Adobe has more than 26,000 employees worldwide. Adobe also has major development operations in the United States in Newton, New York City, Arden Hills, Lehi, Seattle, Austin and San Francisco. It also has major development operations in Noida and Bangalore in India. + +History + +The company was started in John Warnock's garage. The name of the company, Adobe, comes from Adobe Creek in Los Altos, California, a stream which ran behind Warnock's house. That creek is so named because of the type of clay found there (Adobe being a Spanish word for Mudbrick), which alludes to the creative nature of the company's software. Adobe's corporate logo features a stylized "A" and was designed by graphic designer Marva Warnock, John Warnock's wife. In 2020, the company updated its visual identity, including updating its logo to a single color, an all-red logo. + +Steve Jobs attempted to buy the company for $5 million in 1982, but Warnock and Geschke refused. Their investors urged them to work something out with Jobs, so they agreed to sell him shares worth 19 percent of the company. Jobs paid a five-times multiple of their company's valuation at the time, plus a five-year license fee for PostScript, in advance. The purchase and advance made Adobe the first company in the history of Silicon Valley to become profitable in its first year. + +Warnock and Geschke considered various business options including a copy-service business and a turnkey system for office printing. Then they chose to focus on developing specialized printing software and created the Adobe PostScript page description language. + +PostScript was the first truly international standard for computer printing as it included algorithms describing the letter-forms of many languages. Adobe added kanji printer products in 1988. Warnock and Geschke were also able to bolster the credibility of PostScript by connecting with a typesetting manufacturer. They weren't able to work with Compugraphic, but then worked with Linotype to license the Helvetica and Times Roman fonts (through the Linotron 100). By 1987, PostScript had become the industry-standard printer language with more than 400 third-party software programs and licensing agreements with 19 printer companies. + +Warnock described the language as "extensible" in its ability to apply graphic arts standards to office printing. + +Adobe's first products after PostScript were digital fonts which they released in a proprietary format called Type 1, worked on by Bill Paxton after he left Stanford. Apple subsequently developed a competing standard, TrueType, which provided full scalability and precise control of the pixel pattern created by the font's outlines, and licensed it to Microsoft. + +In the mid-1980s, Adobe entered the consumer software market with Illustrator, a vector-based drawing program for the Apple Macintosh. Illustrator, which grew out of the firm's in-house font-development software, helped popularize PostScript-enabled laser printers. + +Adobe entered the NASDAQ Composite index in August 1986. Its revenue has grown from roughly $1 billion in 1999 to $4 billion in 2012. Adobe's fiscal years run from December to November. For example, the 2020 fiscal year ended on November 27, 2020. + +In 1989, Adobe introduced what was to become its flagship product, a graphics editing program for the Macintosh called Photoshop. Stable and full-featured, Photoshop 1.0 was ably marketed by Adobe and soon dominated the market. + +In 1993, Adobe introduced PDF, the Portable Document Format, and its Adobe Acrobat and Reader software. PDF is now an International Standard: ISO 32000-1:2008. + +In December 1991, Adobe released Adobe Premiere, which Adobe rebranded as Adobe Premiere Pro in 2003. In 1992, Adobe acquired OCR Systems, Inc. In 1994, Adobe acquired the Aldus Corporation and added PageMaker and After Effects to its product line later in the year; it also controls the TIFF file format. In the same year, Adobe acquired LaserTools Corp and Compution Inc. In 1995, Adobe added FrameMaker, the long-document DTP application, to its product line after Adobe acquired Frame Technology Corp. In 1996, Adobe acquired Ares Software Corp. In 2002, Adobe acquired Canadian company Accelio (also known as JetForm). + +In May 2003, Adobe purchased audio editing and multitrack recording software Cool Edit Pro from Syntrillium Software for $16.5 million, as well as a large loop library called "Loopology". Adobe then renamed Cool Edit Pro to "Adobe Audition" and included it in the Creative Suite. + +On December 3, 2005, Adobe acquired its main rival, Macromedia, in a stock swap valued at about $3.4 billion, adding ColdFusion, Contribute, Captivate, Breeze (rebranded as Adobe Connect), Director, Dreamweaver, Fireworks, Flash, FlashPaper, Flex, FreeHand, HomeSite, JRun, Presenter, and Authorware to Adobe's product line. + +Adobe released Adobe Media Player in April 2008. On April 27, Adobe discontinued the development and sales of its older HTML/web development software, GoLive, in favor of Dreamweaver. Adobe offered a discount on Dreamweaver for GoLive users and supports those who still use GoLive with online tutorials and migration assistance. On June 1, Adobe launched Acrobat.com, a series of web applications geared for collaborative work. Creative Suite 4, which includes Design, Web, Production Premium, and Master Collection came out in October 2008 in six configurations at prices from about US$1,700 to $2,500 or by individual application. The Windows version of Photoshop includes 64-bit processing. On December 3, 2008, Adobe laid off 600 of its employees (8% of the worldwide staff) citing the weak economic environment. + +On September 15, 2009, Adobe Systems announced that it would acquire online marketing and web analytics company Omniture for $1.8 billion. The deal was completed on October 23, 2009. Former Omniture products were integrated into the Adobe Marketing Cloud. + + On November 10, 2009, the company laid off a further 680 employees. + +Adobe's 2010 was marked by continuing front-and-back arguments with Apple over the latter's non-support for Adobe Flash on its iPhone, iPad and other products. Former Apple CEO Steve Jobs claimed that Flash was not reliable or secure enough, while Adobe executives have argued that Apple wishes to maintain control over the iOS platform. In April 2010, Steve Jobs published a post titled Thoughts on Flash where he outlined his thoughts on Flash and the rise of HTML 5. +In July 2010, Adobe bought Day Software integrating their line of CQ Products: WCM, DAM, SOCO, and Mobile + +In January 2011, Adobe acquired DemDex, Inc. with the intent of adding DemDex's audience-optimization software to its online marketing suite. At Photoshop World 2011, Adobe unveiled a new mobile photo service. Carousel is a new application for iPhone, iPad, and Mac that uses Photoshop Lightroom technology to allow users to adjust and fine-tune images on all platforms. Carousel will also allow users to automatically sync, share and browse photos. The service was later renamed to "Adobe Revel". + +In October 2011, Adobe acquired Nitobi Software, the maker of the mobile application development framework PhoneGap. As part of the acquisition, the source code of PhoneGap was submitted to the Apache Foundation, where it became Apache Cordova. + +In November 2011, Adobe announced that they would cease development of Flash for mobile devices following version 11.1. Instead, it would focus on HTML 5 for mobile devices. In December 2011, Adobe announced that it had entered into a definitive agreement to acquire privately held Efficient Frontier. + +In December 2012, Adobe opened a new corporate campus in Lehi, Utah. + +In 2013, Adobe endured a major security breach. Vast portions of the source code for the company's software were stolen and posted online and over 150 million records of Adobe's customers have been made readily available for download. In 2012, about 40 million sets of payment card information were compromised by a hack at Adobe. + +A class-action lawsuit alleging that the company suppressed employee compensation was filed against Adobe, and three other Silicon Valley-based companies in a California federal district court in 2013. In May 2014, it was revealed the four companies, Adobe, Apple, Google, and Intel had reached an agreement with the plaintiffs, 64,000 employees of the four companies, to pay a sum of $324.5 million to settle the suit. + +In March 2018, at Adobe Summit, the company and Nvidia publicized a key association to quickly upgrade their industry-driving AI and profound learning innovations. Expanding on years of coordinated effort, the organizations will work to streamline the Adobe Sensei AI and machine learning structure for Nvidia GPUs. The joint effort will speed up time to showcase and enhance the execution of new Sensei-powered services for Adobe Creative Cloud and Experience Cloud clients and engineers. + +Adobe and Nvidia have co-operated for over 10 years on empowering GPU quickening for a wide arrangement of Adobe's creative and computerized encounter items. This incorporates Sensei-powered features, for example, auto lip-sync in Adobe Character Animator CC and face-aware editing in Photoshop CC, and also cloud-based AI/ML items and features, for example, picture investigation for Adobe Stock and Lightroom CC and auto-labeling in Adobe Experience Supervisor. + +In May 2018, Adobe stated they would buy e-commerce services provider Magento Commerce from private equity firm Permira for $1.68 billion. This deal will help bolster its Experience Cloud business, which provides services including analytics, advertising, and marketing. The deal is closed on June 19, 2018. + +In September 2018, Adobe announced its acquisition of marketing automation software company Marketo. + +In October 2018, Adobe officially changed its name from Adobe Systems Incorporated to Adobe Inc. + +In January 2019, Adobe announced its acquisition of 3D texturing company Allegorithmic. + +In 2020, the annual Adobe Summit was canceled due to the COVID-19 pandemic. The event took place online and saw over 21 million total video views and over 2.2 million visits to the event website. + +The software giant has imposed a ban on the political ads features on its digital advert sales platform as the United States presidential elections approach. + +On November 9, 2020, Adobe announced it would spend US$1.5 billion to acquire Workfront, a provider of marketing collaboration software. The acquisition was completed in early December 2020. + +On August 19, 2021, Adobe announced it had entered into a definitive agreement to acquire Frame.io, a leading cloud-based video collaboration platform. The transaction is valued at $1.275 billion and closed during the fourth quarter of Adobe's 2021 fiscal year. + +On September 15, 2021, Adobe Inc. formally announced that it will add payment services to its e-commerce platform this year, allowing merchants on their platform a method to accept payments including credit cards and PayPal. + +In September 2022, Adobe announced that it had agreed to buy the software design start-up Figma for $20billion. The cloud-based design software from Figma directly competes with Adobe XD. The deal faces regulatory scrutiny. In February 2023, it was announced the European Commission would review the acquisition under European Union merger regulation (EUMR). + +Finances + +Products + +Adobe's currently supported roster of software, online services and file formats comprises the following (): + +Digital Marketing Management Software + Adobe Experience Cloud, Adobe Experience Manager (AEM 6.2), XML Documentation add-on (for AEM), Mixamo + Formats + Portable Document Format (PDF), PDF's predecessor PostScript, ActionScript, Shockwave Flash (SWF), Flash Video (FLV), and Filmstrip (.flm) + Web-hosted services + Adobe Color, Photoshop Express, Acrobat.com, Behance and Adobe Express. + Adobe Renderer + Adobe Media Encoder + Adobe Stock + A microstock agency that presently provides over 57 million high-resolution, royalty-free images and videos available to license (via subscription or credit purchase methods). In 2015, Adobe acquired Fotolia, a stock content marketplace founded in 2005 by Thibaud Elziere, Oleg Tscheltzoff, and Patrick Chassany which operated in 23 countries. It is run as a stand-alone website. + Adobe Experience Platform + A family of content, development, and customer relationship management products, with what Adobe calls the "next generation" of its Sensei artificial intelligence and machine learning framework, introduced in March 2019. + +Reception +Since 2000, Fortune has recognized Adobe as one of the 100 Best Companies to Work For. In 2021, Adobe was ranked 16th. Glassdoor recognized Adobe as a Best Place to Work. In October 2021, Fast Company included Adobe on their Brands That Matter list. In October 2008, Adobe Systems Canada Inc. was named one of "Canada's Top 100 Employers" by Mediacorp Canada Inc. and was featured in Maclean's newsmagazine. + +Adobe received a five-star rating from the Electronic Frontier Foundation with regard to its handling of government data requests in 2017. + +In 2022, Adobe was listed as one of the Best Places to Work for Disability Inclusion by the Disability Equality Index (DEI). + +Criticisms + +Pricing +Adobe has been criticized for its pricing practices, with retail prices being up to twice as much in non-US countries. For example, it is significantly cheaper to pay for a return airfare ticket to the United States and purchase one particular collection of Adobe's software there than to buy it locally in Australia. + +After Adobe revealed the pricing for the Creative Suite 3 Master Collection, which was £1,000 higher for European customers, a petition to protest over "unfair pricing" was published and signed by 10,000 users. In June 2009, Adobe further increased its prices in the UK by 10% in spite of weakening of the pound against the dollar, and UK users were not allowed to buy from the US store. + +Adobe's Reader and Flash programs were listed on "The 10 most hated programs of all time" article by TechRadar. + +Security +Hackers have exploited vulnerabilities in Adobe programs, such as Adobe Reader, to gain unauthorized access to computers. Adobe's Flash Player has also been criticized for, among other things, suffering from performance, memory usage and security problems (see criticism of Flash Player). A report by security researchers from Kaspersky Lab criticized Adobe for producing the products having top 10 security vulnerabilities. + +Observers noted that Adobe was spying on its customers by including spyware in the Creative Suite 3 software and quietly sending user data to a firm named Omniture. When users became aware, Adobe explained what the suspicious software did and admitted that they: "could and should do a better job taking security concerns into account". When a security flaw was later discovered in Photoshop CS5, Adobe sparked outrage by saying it would leave the flaw unpatched, so anyone who wanted to use the software securely would have to pay for an upgrade. Following a fierce backlash Adobe decided to provide the software patch. + +Adobe has been criticized for pushing unwanted software including third-party browser toolbars and free virus scanners, usually as part of the Flash update process, and for pushing a third-party scareware program designed to scare users into paying for unneeded system repairs. + +Customer data breach +On October 3, 2013, the company initially revealed that 2.9 million customers' sensitive and personal data was stolen in a security breach which included encrypted credit card information. Adobe later admitted that 38 million active users have been affected and the attackers obtained access to their IDs and encrypted passwords, as well as to many inactive Adobe accounts. The company did not make it clear if all the personal information was encrypted, such as email addresses and physical addresses, though data privacy laws in 44 states require this information to be encrypted. + +A 3.8 GB file stolen from Adobe and containing 152 million usernames, reversibly encrypted passwords and unencrypted password hints was posted on AnonNews.org. LastPass, a password security firm, said that Adobe failed to use best practices for securing the passwords and has not salted them. Another security firm, Sophos, showed that Adobe used a weak encryption method permitting the recovery of a lot of information with very little effort. According to IT expert Simon Bain, Adobe has failed its customers and 'should hang their heads in shame'. + +Many of the credit cards were tied to the Creative Cloud software-by-subscription service. Adobe offered its affected US customers a free membership in a credit monitoring service, but no similar arrangements have been made for non-US customers. When a data breach occurs in the US, penalties depend on the state where the victim resides, not where the company is based. + +After stealing the customers' data, cyber-thieves also accessed Adobe's source code repository, likely in mid-August 2013. Because hackers acquired copies of the source code of Adobe proprietary products, they could find and exploit any potential weaknesses in its security, computer experts warned. Security researcher Alex Holden, chief information security officer of Hold Security, characterized this Adobe breach, which affected Acrobat, ColdFusion and numerous other applications, as "one of the worst in US history". Adobe also announced that hackers stole parts of the source code of Photoshop, which according to commentators could allow programmers to copy its engineering techniques and would make it easier to pirate Adobe's expensive products. + +Published on a server of a Russian-speaking hacker group, the "disclosure of encryption algorithms, other security schemes, and software vulnerabilities can be used to bypass protections for individual and corporate data" and may have opened the gateway to new generation zero-day attacks. Hackers already used ColdFusion exploits to make off with usernames and encrypted passwords of PR Newswire's customers, which has been tied to the Adobe security breach. They also used a ColdFusion exploit to breach Washington state court and expose up to 200,000 Social Security numbers. + +Anti-competitive practices +In 1994, Adobe acquired Aldus Corp., a software vendor that sold FreeHand, a competing product. FreeHand was direct competition to Adobe Illustrator, Adobe's flagship vector-graphics editor. The Federal Trade Commission intervened and forced Adobe to sell FreeHand back to Altsys, and also banned Adobe from buying back FreeHand or any similar program for the next 10 years (1994–2004). Altsys was then bought by Macromedia, which released versions 5 to 11. When Adobe acquired Macromedia in December 2005, it stalled development of FreeHand in 2007, effectively rendering it obsolete. With FreeHand and Illustrator, Adobe controlled the only two products that compete in the professional illustration program market for Macintosh operating systems. + +In 2011, a group of 5,000 FreeHand graphic designers convened under the banner Free FreeHand, and filed a civil antitrust complaint in the US District Court for the Northern District of California against Adobe. The suit alleged that Adobe has violated federal and state antitrust laws by abusing its dominant position in the professional vector graphic illustration software market and that Adobe has engaged in a series of exclusionary and anti-competitive acts and strategies designed to kill FreeHand, the dominant competitor to Adobe's Illustrator software product, instead of competing on the basis of product merit according to the principals of free market capitalism. Adobe had no response to the claims and the lawsuit was eventually settled. The FreeHand community believes Adobe should release the product to an open-source community if it cannot update it internally. + +, on its FreeHand product page, Adobe stated, "While we recognize FreeHand has a loyal customer base, we encourage users to migrate to the new Adobe Illustrator CS4 software which supports both PowerPC and Intel-based Macs and Microsoft Windows XP and Windows Vista." , the FreeHand page no longer exists; instead, it simply redirects to the Illustrator page. Adobe's software FTP server still contains a directory for FreeHand, but it is empty. + +Cancellation fees +In April 2021, Adobe received criticism from Twitter users for the company's cancellation fees after a customer shared a tweet showing they had been charged a $291.45 cancellation fee for their Adobe Creative Cloud subscription. Many also showed their cancellation fees for Adobe Creative Cloud, with this leading to many encouraging piracy of Adobe products and/or purchase of alternatives with lower prices or using free and open-source software instead. Furthermore, there have been reports that with changing subscriptions it is possible to avoid paying this fee. + +Chief executive officers +John Warnock (1982–2000) +Bruce Chizen (2000–2007) +Shantanu Narayen (2007–present) + +See also + + Adobe MAX + Digital rights management (DRM) + List of acquisitions by Adobe + United States v.

The American National Center for Complementary and Integrative Health classifies it as a "psychological and physical" complementary approach to health when used "together with" mainstream methods. When used "in place of" conventional medicine, it's considered "alternative". + +Alexander began developing his technique's principles in the 1890s in an attempt to address his own voice loss during public speaking. He credited his method with allowing him to pursue his passion for performing Shakespearean recitations. + +Proponents and teachers of the Alexander Technique believe the technique can address a variety of health conditions, but there is a lack of research to support the claims. , the UK National Health Service cites evidence which suggests that the Alexander Technique may be helpful for long-term back pain and for long-term neck pain, and that it could help people cope with Parkinson's disease. Both the American health-insurance company Aetna and the Australian Department of Health have conducted reviews and concluded that there is insufficient evidence for the technique's health claims to warrant insurance coverage. + +Method + +The Alexander Technique is most commonly taught in a series of private lessons which may last from 30 minutes to an hour. The number of lessons varies widely, depending on the student's needs and level of interest. Students are often performers, such as actors, dancers, musicians, athletes and public speakers, people who work on computers, or those who are in frequent pain for other reasons. Instructors observe their students, and provide both verbal and gentle manual guidance to help students learn how to move with better poise and less strain. Sessions include chair work – often in front of a mirror – during which the instructor will guide the student while the student stands, sits and walks, learning to move efficiently while maintaining a comfortable relationship between the head, neck, and spine, and table work or physical manipulation. + +In the United Kingdom, there is no regulation for who can offer Alexander Technique services. Professional organisations do exist, however, typically offering 3 year courses to people becoming instructors. + +History + +The Alexander Technique is based on the personal observations of Frederick Matthias Alexander (1869–1955). Alexander's career as an actor was hampered by recurrent bouts of laryngitis, but he found he could overcome it by focusing on his discomfort and tension, and relaxing. Alexander also thought posture could be improved if one became more conscious of one's own bodily movement. + +While on a recital tour in New Zealand (1895), Alexander came to believe in the wider significance of improved carriage for overall physical functioning, although evidence from his own publications appears to indicate it happened less systematically and over a long period of time. + +Alexander did not originally conceive of his technique as therapy, but it has become a form of alternative medicine. + +When considering how to classify the Alexander Technique in relation to mainstream medicine, some sources describe it as alternative and/or complementary, depending on whether it is used alone or with mainstream methods. The American National Center for Complementary and Integrative Health classifies it as a "psychological and physical" complementary approach to health when used with mainstream methods. When used "in place of" conventional medicine, it's considered "alternative". + +Influence + +The American philosopher and educator John Dewey became impressed with the Alexander Technique after his headaches, neck pains, blurred vision, and stress symptoms largely improved during the time he used Alexander's advice to change his posture.

He is regarded as the founder of the French school of legal humanists. + +Biography + +Alciati was born in Alzate Brianza, near Milan, and settled in France in the early 16th century. He displayed great literary skill in his exposition of the laws, and was one of the first to interpret the civil law by the history, languages and literature of antiquity, and to substitute original research for the servile interpretations of the glossators. He published many legal works, and some annotations on Tacitus and accumulated a sylloge of Roman inscriptions from Milan and its territories, as part of his preparation for his history of Milan, written in 1504–05. + +Among his several appointments, Alciati taught Law at the University of Bourges between 1529 and 1535. It was Guillaume Budé who encouraged the call to Bourges at the time. Pierre Bayle, in his General Dictionary (article "Alciat"), relates that he greatly increased his salary there, by the "stratagem" of arranging to get a job offer from the University of Bologna and using it as a negotiation point . + +Alciati is most famous for his Emblemata, published in dozens of editions from 1531 onward.

An object's apparent magnitude depends on its intrinsic luminosity, its distance, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer. + +The word magnitude in astronomy, unless stated otherwise, usually refers to a celestial object's apparent magnitude. The magnitude scale dates back to the ancient Roman astronomer Claudius Ptolemy, whose star catalog listed stars from 1st magnitude (brightest) to 6th magnitude (dimmest). The modern scale was mathematically defined in a way to closely match this historical system. + +The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to a brightness ratio of , or about 2.512. For example, a star of magnitude 2.0 is 2.512 times as bright as a star of magnitude 3.0, 6.31 times as bright as a star of magnitude 4.0, and 100 times as bright as one of magnitude 7.0. + +Differences in astronomical magnitudes can also be related to another logarithmic ratio scale, the decibel: an increase of one astronomical magnitude is exactly equal to a decrease of 4 decibels (dB). + +The brightest astronomical objects have negative apparent magnitudes: for example, Venus at −4.2 or Sirius at −1.46. The faintest stars visible with the naked eye on the darkest night have apparent magnitudes of about +6.5, though this varies depending on a person's eyesight and with altitude and atmospheric conditions. The apparent magnitudes of known objects range from the Sun at −26.832 to objects in deep Hubble Space Telescope images of magnitude +31.5. + +The measurement of apparent magnitude is called photometry. Photometric measurements are made in the ultraviolet, visible, or infrared wavelength bands using standard passband filters belonging to photometric systems such as the UBV system or the Strömgren uvbyβ system. + +Absolute magnitude is a measure of the intrinsic luminosity of a celestial object, rather than its apparent brightness, and is expressed on the same reverse logarithmic scale. Absolute magnitude is defined as the apparent magnitude that a star or object would have if it were observed from a distance of . Therefore, it is of greater use in stellar astrophysics since it refers to a property of a star regardless of how close it is to Earth. But in observational astronomy and popular stargazing, unqualified references to "magnitude" are understood to mean apparent magnitude. + +Amateur astronomers commonly express the darkness of the sky in terms of limiting magnitude, i.e. the apparent magnitude of the faintest star they can see with the naked eye. This can be useful as a way of monitoring the spread of light pollution. + +Apparent magnitude is really a measure of illuminance, which can also be measured in photometric units such as lux. + +History + +The scale used to indicate magnitude originates in the Hellenistic practice of dividing stars visible to the naked eye into six magnitudes. The brightest stars in the night sky were said to be of first magnitude ( = 1), whereas the faintest were of sixth magnitude ( = 6), which is the limit of human visual perception (without the aid of a telescope). Each grade of magnitude was considered twice the brightness of the following grade (a logarithmic scale), although that ratio was subjective as no photodetectors existed. This rather crude scale for the brightness of stars was popularized by Ptolemy in his Almagest and is generally believed to have originated with Hipparchus. This cannot be proved or disproved because Hipparchus's original star catalogue is lost. The only preserved text by Hipparchus himself (a commentary to Aratus) clearly documents that he did not have a system to describe brightness with numbers: He always uses terms like "big" or "small", "bright" or "faint" or even descriptions such as "visible at full moon". + +In 1856, Norman Robert Pogson formalized the system by defining a first magnitude star as a star that is 100 times as bright as a sixth-magnitude star, thereby establishing the logarithmic scale still in use today. This implies that a star of magnitude is about 2.512 times as bright as a star of magnitude . This figure, the fifth root of 100, became known as Pogson's Ratio. The zero point of Pogson's scale was originally defined by assigning Polaris a magnitude of exactly 2. Astronomers later discovered that Polaris is slightly variable, so they switched to Vega as the standard reference star, assigning the brightness of Vega as the definition of zero magnitude at any specified wavelength. + +Apart from small corrections, the brightness of Vega still serves as the definition of zero magnitude for visible and near infrared wavelengths, where its spectral energy distribution (SED) closely approximates that of a black body for a temperature of . However, with the advent of infrared astronomy it was revealed that Vega's radiation includes an infrared excess presumably due to a circumstellar disk consisting of dust at warm temperatures (but much cooler than the star's surface). At shorter (e.g. visible) wavelengths, there is negligible emission from dust at these temperatures. However, in order to properly extend the magnitude scale further into the infrared, this peculiarity of Vega should not affect the definition of the magnitude scale. Therefore, the magnitude scale was extrapolated to all wavelengths on the basis of the black-body radiation curve for an ideal stellar surface at uncontaminated by circumstellar radiation. On this basis the spectral irradiance (usually expressed in janskys) for the zero magnitude point, as a function of wavelength, can be computed. Small deviations are specified between systems using measurement apparatuses developed independently so that data obtained by different astronomers can be properly compared, but of greater practical importance is the definition of magnitude not at a single wavelength but applying to the response of standard spectral filters used in photometry over various wavelength bands. + +With the modern magnitude systems, brightness over a very wide range is specified according to the logarithmic definition detailed below, using this zero reference. In practice such apparent magnitudes do not exceed 30 (for detectable measurements). The brightness of Vega is exceeded by four stars in the night sky at visible wavelengths (and more at infrared wavelengths) as well as the bright planets Venus, Mars, and Jupiter, and these must be described by negative magnitudes. For example, Sirius, the brightest star of the celestial sphere, has a magnitude of −1.4 in the visible. Negative magnitudes for other very bright astronomical objects can be found in the table below. + +Astronomers have developed other photometric zero point systems as alternatives to the Vega system. The most widely used is the AB magnitude system, in which photometric zero points are based on a hypothetical reference spectrum having constant flux per unit frequency interval, rather than using a stellar spectrum or blackbody curve as the reference. The AB magnitude zero point is defined such that an object's AB and Vega-based magnitudes will be approximately equal in the V filter band. + +Measurement + +Precision measurement of magnitude (photometry) requires calibration of the photographic or (usually) electronic detection apparatus. This generally involves contemporaneous observation, under identical conditions, of standard stars whose magnitude using that spectral filter is accurately known. Moreover, as the amount of light actually received by a telescope is reduced due to transmission through the Earth's atmosphere, the airmasses of the target and calibration stars must be taken into account. Typically one would observe a few different stars of known magnitude which are sufficiently similar. Calibrator stars close in the sky to the target are favoured (to avoid large differences in the atmospheric paths). If those stars have somewhat different zenith angles (altitudes) then a correction factor as a function of airmass can be derived and applied to the airmass at the target's position. Such calibration obtains the brightness as would be observed from above the atmosphere, where apparent magnitude is defined. + +The apparent magnitude scale in astronomy reflects the received power of stars and not their amplitude. Newcomers should consider using the relative brightness measure in astrophotography to adjust exposure times between stars. Apparent magnitude also integrates over the entire object, regardless of its focus, and this needs to be taken into account when scaling exposure times for objects with significant apparent size, like the Sun, Moon and planets. For example, directly scaling the exposure time from the Moon to the Sun works because they are approximately the same size in the sky. However, scaling the exposure from the Moon to Saturn would result in an overexposure if the image of Saturn takes up a smaller area on your sensor than the Moon did (at the same magnification, or more generally, f/#). + +Calculations + +The dimmer an object appears, the higher the numerical value given to its magnitude, with a difference of 5 magnitudes corresponding to a brightness factor of exactly 100. Therefore, the magnitude , in the spectral band , would be given by + +which is more commonly expressed in terms of common (base-10) logarithms as + +where is the observed irradiance using spectral filter , and is the reference flux (zero-point) for that photometric filter. Since an increase of 5 magnitudes corresponds to a decrease in brightness by a factor of exactly 100, each magnitude increase implies a decrease in brightness by the factor (Pogson's ratio). Inverting the above formula, a magnitude difference implies a brightness factor of + +Example: Sun and Moon +What is the ratio in brightness between the Sun and the full Moon? + +The apparent magnitude of the Sun is −26.832 (brighter), and the mean magnitude of the full moon is −12.74 (dimmer). + +Difference in magnitude: + +Brightness factor: + +The Sun appears about times as bright as the full Moon. + +Magnitude addition +Sometimes one might wish to add brightness. For example, photometry on closely separated double stars may only be able to produce a measurement of their combined light output. To find the combined magnitude of that double star knowing only the magnitudes of the individual components, this can be done by adding the brightness (in linear units) corresponding to each magnitude. + +Solving for yields + +where is the resulting magnitude after adding the brightnesses referred to by and . + +Apparent bolometric magnitude +While magnitude generally refers to a measurement in a particular filter band corresponding to some range of wavelengths, the apparent or absolute bolometric magnitude (mbol) is a measure of an object's apparent or absolute brightness integrated over all wavelengths of the electromagnetic spectrum (also known as the object's irradiance or power, respectively). The zero point of the apparent bolometric magnitude scale is based on the definition that an apparent bolometric magnitude of 0 mag is equivalent to a received irradiance of 2.518×10−8 watts per square metre (W·m−2). + +Absolute magnitude + +While apparent magnitude is a measure of the brightness of an object as seen by a particular observer, absolute magnitude is a measure of the intrinsic brightness of an object. Flux decreases with distance according to an inverse-square law, so the apparent magnitude of a star depends on both its absolute brightness and its distance (and any extinction). For example, a star at one distance will have the same apparent magnitude as a star four times as bright at twice that distance. In contrast, the intrinsic brightness of an astronomical object, does not depend on the distance of the observer or any extinction. + +The absolute magnitude , of a star or astronomical object is defined as the apparent magnitude it would have as seen from a distance of . The absolute magnitude of the Sun is 4.83 in the V band (visual), 4.68 in the Gaia satellite's G band (green) and 5.48 in the B band (blue). + +In the case of a planet or asteroid, the absolute magnitude rather means the apparent magnitude it would have if it were from both the observer and the Sun, and fully illuminated at maximum opposition (a configuration that is only theoretically achievable, with the observer situated on the surface of the Sun). + +Standard reference values + +The magnitude scale is a reverse logarithmic scale. A common misconception is that the logarithmic nature of the scale is because the human eye itself has a logarithmic response. In Pogson's time this was thought to be true (see Weber–Fechner law), but it is now believed that the response is a power law . + +Magnitude is complicated by the fact that light is not monochromatic. The sensitivity of a light detector varies according to the wavelength of the light, and the way it varies depends on the type of light detector. For this reason, it is necessary to specify how the magnitude is measured for the value to be meaningful. For this purpose the UBV system is widely used, in which the magnitude is measured in three different wavelength bands: U (centred at about 350 nm, in the near ultraviolet), B (about 435 nm, in the blue region) and V (about 555 nm, in the middle of the human visual range in daylight). The V band was chosen for spectral purposes and gives magnitudes closely corresponding to those seen by the human eye. When an apparent magnitude is discussed without further qualification, the V magnitude is generally understood. + +Because cooler stars, such as red giants and red dwarfs, emit little energy in the blue and UV regions of the spectrum, their power is often under-represented by the UBV scale. Indeed, some L and T class stars have an estimated magnitude of well over 100, because they emit extremely little visible light, but are strongest in infrared. + +Measures of magnitude need cautious treatment and it is extremely important to measure like with like. On early 20th century and older orthochromatic (blue-sensitive) photographic film, the relative brightnesses of the blue supergiant Rigel and the red supergiant Betelgeuse irregular variable star (at maximum) are reversed compared to what human eyes perceive, because this archaic film is more sensitive to blue light than it is to red light. Magnitudes obtained from this method are known as photographic magnitudes, and are now considered obsolete. + +For objects within the Milky Way with a given absolute magnitude, 5 is added to the apparent magnitude for every tenfold increase in the distance to the object. For objects at very great distances (far beyond the Milky Way), this relationship must be adjusted for redshifts and for non-Euclidean distance measures due to general relativity. + +For planets and other Solar System bodies, the apparent magnitude is derived from its phase curve and the distances to the Sun and observer. + +List of apparent magnitudes + +Some of the listed magnitudes are approximate. Telescope sensitivity depends on observing time, optical bandpass, and interfering light from scattering and airglow. + +See also + Distance modulus + List of nearest bright stars + List of nearest stars and brown dwarfs + Luminosity in astronomy + Surface brightness + +References + +External links + + +Observational astronomy +Logarithmic scales of measurement +In astronomy, absolute magnitude () is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale. An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly , without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust. By hypothetically placing all objects at a standard reference distance from the observer, their luminosities can be directly compared among each other on a magnitude scale. For Solar System bodies that shine in reflected light, a different definition of absolute magnitude (H) is used, based on a standard reference distance of one astronomical unit. + +Absolute magnitudes of stars generally range from approximately −10 to +20. The absolute magnitudes of galaxies can be much lower (brighter). + +The more luminous an object, the smaller the numerical value of its absolute magnitude. A difference of 5 magnitudes between the absolute magnitudes of two objects corresponds to a ratio of 100 in their luminosities, and a difference of n magnitudes in absolute magnitude corresponds to a luminosity ratio of 100n/5. For example, a star of absolute magnitude MV = 3.0 would be 100 times as luminous as a star of absolute magnitude MV = 8.0 as measured in the V filter band. The Sun has absolute magnitude MV = +4.83. Highly luminous objects can have negative absolute magnitudes: for example, the Milky Way galaxy has an absolute B magnitude of about −20.8. + +As with all astronomical magnitudes, the absolute magnitude can be specified for different wavelength ranges corresponding to specified filter bands or passbands; for stars a commonly quoted absolute magnitude is the absolute visual magnitude, which uses the visual (V) band of the spectrum (in the UBV photometric system). Absolute magnitudes are denoted by a capital M, with a subscript representing the filter band used for measurement, such as MV for absolute magnitude in the V band. + +An object's absolute bolometric magnitude (Mbol) represents its total luminosity over all wavelengths, rather than in a single filter band, as expressed on a logarithmic magnitude scale. To convert from an absolute magnitude in a specific filter band to absolute bolometric magnitude, a bolometric correction (BC) is applied. + +Stars and galaxies +In stellar and galactic astronomy, the standard distance is 10 parsecs (about 32.616 light-years, 308.57 petameters or 308.57 trillion kilometres). A star at 10 parsecs has a parallax of 0.1″ (100 milliarcseconds). Galaxies (and other extended objects) are much larger than 10 parsecs, their light is radiated over an extended patch of sky, and their overall brightness cannot be directly observed from relatively short distances, but the same convention is used. A galaxy's magnitude is defined by measuring all the light radiated over the entire object, treating that integrated brightness as the brightness of a single point-like or star-like source, and computing the magnitude of that point-like source as it would appear if observed at the standard 10 parsecs distance. Consequently, the absolute magnitude of any object equals the apparent magnitude it would have if it were 10 parsecs away. + +Some stars visible to the naked eye have such a low absolute magnitude that they would appear bright enough to outshine the planets and cast shadows if they were at 10 parsecs from the Earth. Examples include Rigel (−7.0), Deneb (−7.2), Naos (−6.0), and Betelgeuse (−5.6). For comparison, Sirius has an absolute magnitude of only 1.4, which is still brighter than the Sun, whose absolute visual magnitude is 4.83. The Sun's absolute bolometric magnitude is set arbitrarily, usually at 4.75. +Absolute magnitudes of stars generally range from approximately −10 to +20. The absolute magnitudes of galaxies can be much lower (brighter). For example, the giant elliptical galaxy M87 has an absolute magnitude of −22 (i.e. as bright as about 60,000 stars of magnitude −10). Some active galactic nuclei (quasars like CTA-102) can reach absolute magnitudes in excess of −32, making them the most luminous persistent objects in the observable universe, although these objects can vary in brightness over astronomically short timescales. At the extreme end, the optical afterglow of the gamma ray burst GRB 080319B reached, according to one paper, an absolute r magnitude brighter than −38 for a few tens of seconds. + +Apparent magnitude + +The Greek astronomer Hipparchus established a numerical scale to describe the brightness of each star appearing in the sky. The brightest stars in the sky were assigned an apparent magnitude , and the dimmest stars visible to the naked eye are assigned . The difference between them corresponds to a factor of 100 in brightness. For objects within the immediate neighborhood of the Sun, the absolute magnitude and apparent magnitude from any distance (in parsecs, with 1 pc = 3.2616 light-years) are related by + +where is the radiant flux measured at distance (in parsecs), the radiant flux measured at distance . Using the common logarithm, the equation can be written as + +where it is assumed that extinction from gas and dust is negligible. Typical extinction rates within the Milky Way galaxy are 1 to 2 magnitudes per kiloparsec, when dark clouds are taken into account. + +For objects at very large distances (outside the Milky Way) the luminosity distance (distance defined using luminosity measurements) must be used instead of , because the Euclidean approximation is invalid for distant objects. Instead, general relativity must be taken into account. Moreover, the cosmological redshift complicates the relationship between absolute and apparent magnitude, because the radiation observed was shifted into the red range of the spectrum. To compare the magnitudes of very distant objects with those of local objects, a K correction might have to be applied to the magnitudes of the distant objects. + +The absolute magnitude can also be written in terms of the apparent magnitude and stellar parallax : + +or using apparent magnitude and distance modulus : + +Examples +Rigel has a visual magnitude of 0.12 and distance of about 860 light-years: + +Vega has a parallax of 0.129″, and an apparent magnitude of 0.03: + +The Black Eye Galaxy has a visual magnitude of 9.36 and a distance modulus of 31.06: + +Bolometric magnitude + +The absolute bolometric magnitude () takes into account electromagnetic radiation at all wavelengths. It includes those unobserved due to instrumental passband, the Earth's atmospheric absorption, and extinction by interstellar dust. It is defined based on the luminosity of the stars. In the case of stars with few observations, it must be computed assuming an effective temperature. + +Classically, the difference in bolometric magnitude is related to the luminosity ratio according to: + +which makes by inversion: + +where + is the Sun's luminosity (bolometric luminosity) + is the star's luminosity (bolometric luminosity) + is the bolometric magnitude of the Sun + is the bolometric magnitude of the star. + +In August 2015, the International Astronomical Union passed Resolution B2 defining the zero points of the absolute and apparent bolometric magnitude scales in SI units for power (watts) and irradiance (W/m2), respectively. Although bolometric magnitudes had been used by astronomers for many decades, there had been systematic differences in the absolute magnitude-luminosity scales presented in various astronomical references, and no international standardization. This led to systematic differences in bolometric corrections scales. Combined with incorrect assumed absolute bolometric magnitudes for the Sun, this could lead to systematic errors in estimated stellar luminosities (and other stellar properties, such as radii or ages, which rely on stellar luminosity to be calculated). + +Resolution B2 defines an absolute bolometric magnitude scale where corresponds to luminosity , with the zero point luminosity set such that the Sun (with nominal luminosity ) corresponds to absolute bolometric magnitude . Placing a radiation source (e.g. star) at the standard distance of 10 parsecs, it follows that the zero point of the apparent bolometric magnitude scale corresponds to irradiance . Using the IAU 2015 scale, the nominal total solar irradiance ("solar constant") measured at 1 astronomical unit () corresponds to an apparent bolometric magnitude of the Sun of . + +Following Resolution B2, the relation between a star's absolute bolometric magnitude and its luminosity is no longer directly tied to the Sun's (variable) luminosity: + +where + is the star's luminosity (bolometric luminosity) in watts + is the zero point luminosity + is the bolometric magnitude of the star + +The new IAU absolute magnitude scale permanently disconnects the scale from the variable Sun. However, on this SI power scale, the nominal solar luminosity corresponds closely to , a value that was commonly adopted by astronomers before the 2015 IAU resolution. + +The luminosity of the star in watts can be calculated as a function of its absolute bolometric magnitude as: + +using the variables as defined previously. + +Solar System bodies () + +For planets and asteroids, a definition of absolute magnitude that is more meaningful for non-stellar objects is used. The absolute magnitude, commonly called , is defined as the apparent magnitude that the object would have if it were one astronomical unit (AU) from both the Sun and the observer, and in conditions of ideal solar opposition (an arrangement that is impossible in practice). Because Solar System bodies are illuminated by the Sun, their brightness varies as a function of illumination conditions, described by the phase angle. This relationship is referred to as the phase curve. The absolute magnitude is the brightness at phase angle zero, an arrangement known as opposition, from a distance of one AU. + +Apparent magnitude + +The absolute magnitude can be used to calculate the apparent magnitude of a body. For an object reflecting sunlight, and are connected by the relation + +where is the phase angle, the angle between the body-Sun and body–observer lines. is the phase integral (the integration of reflected light; a number in the 0 to 1 range). + +By the law of cosines, we have: + +Distances: + is the distance between the body and the observer + is the distance between the body and the Sun + is the distance between the observer and the Sun + , a unit conversion factor, is the constant 1 AU, the average distance between the Earth and the Sun + +Approximations for phase integral +The value of depends on the properties of the reflecting surface, in particular on its roughness. In practice, different approximations are used based on the known or assumed properties of the surface.

A more accurate formula is given in the following section. + +More advanced models + +Because Solar System bodies are never perfect diffuse reflectors, astronomers use different models to predict apparent magnitudes based on known or assumed properties of the body. For planets, approximations for the correction term in the formula for have been derived empirically, to match observations at different phase angles.

Neptune's absolute magnitude is changing slowly due to seasonal effects as the planet moves along its 165-year orbit around the Sun, and the approximation above is only valid after the year 2000. For some circumstances, like for Venus, no observations are available, and the phase curve is unknown in those cases. The formula for the Moon is only applicable to the near side of the Moon, the portion that is visible from the Earth. + +Example 1: On 1 January 2019, Venus was from the Sun, and from Earth, at a phase angle of (near quarter phase). Under full-phase conditions, Venus would have been visible at Accounting for the high phase angle, the correction term above yields an actual apparent magnitude of This is close to the value of predicted by the Jet Propulsion Laboratory. + +Example 2: At first quarter phase, the approximation for the Moon gives With that, the apparent magnitude of the Moon is close to the expected value of about . At last quarter, the Moon is about 0.06 mag fainter than at first quarter, because that part of its surface has a lower albedo. + +Earth's albedo varies by a factor of 6, from 0.12 in the cloud-free case to 0.76 in the case of altostratus cloud. The absolute magnitude in the table corresponds to an albedo of 0.434. Due to the variability of the weather, Earth's apparent magnitude cannot be predicted as accurately as that of most other planets. + +Asteroids + +If an object has an atmosphere, it reflects light more or less isotropically in all directions, and its brightness can be modelled as a diffuse reflector. Bodies with no atmosphere, like asteroids or moons, tend to reflect light more strongly to the direction of the incident light, and their brightness increases rapidly as the phase angle approaches . This rapid brightening near opposition is called the opposition effect. Its strength depends on the physical properties of the body's surface, and hence it differs from asteroid to asteroid. + +In 1985, the IAU adopted the semi-empirical -system, based on two parameters and called absolute magnitude and slope, to model the opposition effect for the ephemerides published by the Minor Planet Center. + +where +the phase integral is and + for or , , , and . + +This relation is valid for phase angles , and works best when . + +The slope parameter relates to the surge in brightness, typically , when the object is near opposition.

An example is 101955 Bennu, with . + +In 2012, the -system was officially replaced by an improved system with three parameters , and , which produces more satisfactory results if the opposition effect is very small or restricted to very small phase angles. However, as of 2022, this -system has not been adopted by either the Minor Planet Center nor Jet Propulsion Laboratory. + +The apparent magnitude of asteroids varies as they rotate, on time scales of seconds to weeks depending on their rotation period, by up to or more. In addition, their absolute magnitude can vary with the viewing direction, depending on their axial tilt. In many cases, neither the rotation period nor the axial tilt are known, limiting the predictability. The models presented here do not capture those effects. + +Cometary magnitudes +The brightness of comets is given separately as total magnitude (, the brightness integrated over the entire visible extend of the coma) and nuclear magnitude (, the brightness of the core region alone). Both are different scales than the magnitude scale used for planets and asteroids, and can not be used for a size comparison with an asteroid's absolute magnitude . + +The activity of comets varies with their distance from the Sun. Their brightness can be approximated as + +where are the total and nuclear apparent magnitudes of the comet, respectively, are its "absolute" total and nuclear magnitudes, and are the body-sun and body-observer distances, is the Astronomical Unit, and are the slope parameters characterising the comet's activity. For , this reduces to the formula for a purely reflecting body (showing no cometary activity). + +For example, the lightcurve of comet C/2011 L4 (PANSTARRS) can be approximated by On the day of its perihelion passage, 10 March 2013, comet PANSTARRS was from the Sun and from Earth. The total apparent magnitude is predicted to have been at that time. The Minor Planet Center gives a value close to that, . + +The absolute magnitude of any given comet can vary dramatically. It can change as the comet becomes more or less active over time or if it undergoes an outburst. This makes it difficult to use the absolute magnitude for a size estimate. When comet 289P/Blanpain was discovered in 1819, its absolute magnitude was estimated as . It was subsequently lost and was only rediscovered in 2003. At that time, its absolute magnitude had decreased to , and it was realised that the 1819 apparition coincided with an outburst. 289P/Blanpain reached naked eye brightness (5–8 mag) in 1819, even though it is the comet with the smallest nucleus that has ever been physically characterised, and usually doesn't become brighter than 18 mag. + +For some comets that have been observed at heliocentric distances large enough to distinguish between light reflected from the coma, and light from the nucleus itself, an absolute magnitude analogous to that used for asteroids has been calculated, allowing to estimate the sizes of their nuclei. + +Meteors +For a meteor, the standard distance for measurement of magnitudes is at an altitude of at the observer's zenith. + +See also + Araucaria Project + Hertzsprung–Russell diagram – relates absolute magnitude or luminosity versus spectral color or surface temperature. + Jansky radio astronomer's preferred unit – linear in power/unit area + List of most luminous stars + Photographic magnitude + Surface brightness – the magnitude for extended objects + Zero point (photometry) – the typical calibration point for star flux + +References + +External links + Reference zero-magnitude fluxes + International Astronomical Union + Absolute Magnitude of a Star calculator + The Magnitude system + About stellar magnitudes + Obtain the magnitude of any star – SIMBAD + Converting magnitude of minor planets to diameter + Another table for converting asteroid magnitude to estimated diameter + +Observational astronomy +Apollo 1, initially designated AS-204, was planned to be the first crewed mission of the Apollo program, the American undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module. The mission never flew; a cabin fire during a launch rehearsal test at Cape Kennedy Air Force Station Launch Complex 34 on January 27 killed all three crew members—Command Pilot Gus Grissom, Senior Pilot Ed White, and Pilot Roger B. Chaffee—and destroyed the command module (CM). The name Apollo 1, chosen by the crew, was made official by NASA in their honor after the fire. + +Immediately after the fire, NASA convened an Accident Review Board to determine the cause of the fire, and both chambers of the United States Congress conducted their own committee inquiries to oversee NASA's investigation. The ignition source of the fire was determined to be electrical, and the fire spread rapidly due to combustible nylon material and the high-pressure pure oxygen cabin atmosphere. Rescue was prevented by the plug door hatch, which could not be opened against the internal pressure of the cabin. Because the rocket was unfueled, the test had not been considered hazardous, and emergency preparedness for it was poor. + +During the Congressional investigation, Senator Walter Mondale publicly revealed a NASA internal document citing problems with prime Apollo contractor North American Aviation, which became known as the Phillips Report. This disclosure embarrassed NASA Administrator James E. Webb, who was unaware of the document's existence, and attracted controversy to the Apollo program. Despite congressional displeasure at NASA's lack of openness, both congressional committees ruled that the issues raised in the report had no bearing on the accident. + +Crewed Apollo flights were suspended for twenty months while the command module's hazards were addressed. However, the development and uncrewed testing of the lunar module (LM) and Saturn V rocket continued. The Saturn IB launch vehicle for Apollo1, SA-204, was used for the first LM test flight, Apollo 5. The first successful crewed Apollo mission was flown by Apollo1's backup crew on Apollo 7 in October 1968. + +Crew + +First backup crew (April–December 1966) + +Second backup crew (December 1966 – January 1967) + +Apollo crewed test flight plans + +AS-204 was to be the first crewed test flight of the Apollo command and service module (CSM) to Earth orbit, launched on a Saturn IB rocket. AS-204 was to test launch operations, ground tracking and control facilities and the performance of the Apollo-Saturn launch assembly and would have lasted up to two weeks, depending on how the spacecraft performed. + +The CSM for this flight, number 012 built by North American Aviation (NAA), was a Block I version designed before the lunar orbit rendezvous landing strategy was chosen; therefore it lacked the capability of docking with the lunar module. This was incorporated into the Block II CSM design, along with lessons learned in Block I. Block II would be test-flown with the LM when the latter was ready. + +Director of Flight Crew Operations Deke Slayton selected the first Apollo crew in January 1966, with Grissom as Command Pilot, White as Senior Pilot, and rookie Donn F. Eisele as Pilot. But Eisele dislocated his shoulder twice aboard the KC-135 weightlessness training aircraft, and had to undergo surgery on January 27. Slayton replaced him with Chaffee, and NASA announced the crew selection on March 21, 1966. James McDivitt, David Scott and Russell Schweickart were named as the backup crew. + +On September 29, Walter Schirra, Eisele, and Walter Cunningham were named as the prime crew for a second Block I CSM flight, AS-205. NASA planned to follow this with an uncrewed test flight of the LM (AS-206), then the third crewed mission would be a dual flight designated AS-278 (or AS-207/208), in which AS-207 would launch the first crewed Block II CSM, which would then rendezvous and dock with the LM launched uncrewed on AS-208. + +In March, NASA was studying the possibility of flying the first Apollo mission as a joint space rendezvous with the final Project Gemini mission, Gemini 12 in November 1966. But by May, delays in making Apollo ready for flight just by itself, and the extra time needed to incorporate compatibility with the Gemini, made that impractical. This became moot when slippage in readiness of the AS-204 spacecraft caused the last-quarter 1966 target date to be missed, and the mission was rescheduled for February 21, 1967. + +Mission background + +In October 1966, NASA announced the flight would carry a small television camera to broadcast live from the command module. The camera would also be used to allow flight controllers to monitor the spacecraft's instrument panel in flight. Television cameras were carried aboard all crewed Apollo missions. + +Insignia +Grissom's crew received approval in June 1966 to design a mission patch with the name Apollo1 (though the approval was subsequently withdrawn pending a final decision on the mission designation, which was not resolved until after the fire). The design's center depicts a command and service module flying over the southeastern United States with Florida (the launch point) prominent. The Moon is seen in the distance, symbolic of the eventual program goal. A yellow border carries the mission and astronaut names with another border set with stars and stripes, trimmed in gold. The insignia was designed by the crew, with the artwork done by North American Aviation employee Allen Stevens. + +Spacecraft and crew preparation + +The Apollo command and service module was much bigger and far more complex than any previous crewed spacecraft. In October 1963, Joseph F. Shea was named Apollo Spacecraft Program Office (ASPO) manager, responsible for managing the design and construction of both the CSM and the LM. +In a spacecraft review meeting held with Shea on August 19, 1966 (a week before delivery), the crew expressed concern about the amount of flammable material (mainly nylon netting and Velcro) in the cabin, which both astronauts and technicians found convenient for holding tools and equipment in place. Although Shea gave the spacecraft a passing grade, after the meeting they gave him a crew portrait they had posed with heads bowed and hands clasped in prayer, with the inscription: + +Shea gave his staff orders to tell North American to remove the flammables from the cabin, but did not supervise the issue personally. + +North American shipped spacecraft CM-012 to Kennedy Space Center on August 26, 1966, under a conditional Certificate of Flight Worthiness: 113 significant incomplete planned engineering changes had to be completed at KSC. That was not all; an additional 623 engineering change orders were made and completed after delivery. Grissom became so frustrated with the inability of the training simulator engineers to keep up with the spacecraft changes that he took a lemon from a tree by his house and hung it on the simulator. + +The command and service modules were mated in the KSC altitude chamber in September, and combined system testing was performed. Altitude testing was performed first uncrewed, then with both the prime and backup crews, from October 10 through December 30. During this testing, the environmental control unit in the command module was found to have a design flaw, and was sent back to the manufacturer for design changes and rework. The returned ECU then leaked water/glycol coolant, and had to be returned a second time. Also during this time, a propellant tank in another service module had ruptured during testing at NAA, prompting the removal from the KSC test chamber of the service module so it could be tested for signs of the tank problem. These tests were negative. + +In December the second Block I flight AS-205 was canceled as unnecessary; Schirra, Eisele and Cunningham were reassigned as the backup crew for Apollo1. McDivitt's crew was now promoted to prime crew of the Block II/LM mission, re-designated AS-258 because the AS-205 launch vehicle would be used in place of AS-207. A third crewed mission was planned to launch the CSM and LM together on a SaturnV (AS-503) to an elliptical medium Earth orbit (MEO), to be crewed by Frank Borman, Michael Collins and William Anders. McDivitt, Scott and Schweickart had started their training for AS-258 in CM-101 at the NAA plant in Downey, California, when the Apollo1 accident occurred. + +Once all outstanding CSM-012 hardware problems had been fixed, the reassembled spacecraft completed a successful altitude chamber test with Schirra's backup crew on December 30. According to the final report of the accident investigation board, "At the post-test debriefing the backup flight crew expressed their satisfaction with the condition and performance of the spacecraft." This would appear to contradict the account given in the 1994 book Lost Moon: The Perilous Voyage of Apollo13 by Jeffrey Kluger and astronaut James Lovell, that "When the trio climbed out of the ship,... Schirra made it clear that he was not pleased with what he had seen," and that he later warned Grissom and Shea that "there's nothing wrong with this ship that I can point to, but it just makes me uncomfortable. Something about it just doesn't ring right," and that Grissom should get out at the first sign of trouble. + +After the successful altitude tests, the spacecraft was removed from the altitude chamber on January 3, 1967, and mated to its Saturn IB launch vehicle on pad 34 on January 6. + +Grissom said in a February 1963 interview that NASA could not eliminate risk despite precautions: + +"I suppose that someday we are going to have a failure. In every other business there are failures, and they are bound to happen sooner or later", he added. Grissom was asked about the fear of potential catastrophe in a December 1966 interview: + +Accident + +Plugs-out test + +The launch simulation on January 27, 1967, on pad 34, was a "plugs-out" test to determine whether the spacecraft would operate nominally on (simulated) internal power while detached from all cables and umbilicals. Passing this test was essential to making the February 21 launch date. The test was considered non-hazardous because neither the launch vehicle nor the spacecraft was loaded with fuel or cryogenics and all pyrotechnic systems (explosive bolts) were disabled. + +At 1:00 pm EST (1800 GMT) on January 27, first Grissom, then Chaffee, and White entered the command module fully pressure-suited, and were strapped into their seats and hooked up to the spacecraft's oxygen and communication systems. Grissom immediately noticed a strange odor in the air circulating through his suit which he compared to "sour buttermilk", and the simulated countdown was put on hold at 1:20 pm, while air samples were taken. No cause of the odor could be found, and the countdown was resumed at 2:42 pm. The accident investigation found this odor not to be related to the fire. + +Three minutes after the count was resumed the hatch installation was started. The hatch consisted of three parts: a removable inner hatch which stayed inside the cabin; a hinged outer hatch which was part of the spacecraft's heat shield; and an outer hatch cover which was part of the boost protective cover enveloping the entire command module to protect it from aerodynamic heating during launch and from launch escape rocket exhaust in the event of a launch abort. The boost hatch cover was partially, but not fully, latched in place because the flexible boost protective cover was slightly distorted by some cabling run under it to provide the simulated internal power (the spacecraft's fuel cell reactants were not loaded for this test). After the hatches were sealed, the air in the cabin was replaced with pure oxygen at , higher than atmospheric pressure. + +Movement by the astronauts was detected by the spacecraft's inertial measurement unit and the astronauts' biomedical sensors, and also indicated by increases in oxygen spacesuit flow, and sounds from Grissom's stuck-open microphone. The stuck microphone was part of a problem with the communications loop connecting the crew, the Operations and Checkout Building, and the Complex 34 blockhouse control room. The poor communications led Grissom to remark: "How are we going to get to the Moon if we can't talk between two or three buildings?" + +The simulated countdown was put on hold again at 5:40 pm while attempts were made to troubleshoot the communications problem. All countdown functions up to the simulated internal power transfer had been successfully completed by 6:20 pm, and at 6:30 the count remained on hold at T minus 10 minutes. + +Fire + +The crew members were using the time to run through their checklist again, when a momentary increase in AC Bus2 voltage occurred. Nine seconds later (at 6:31:04.7), one of the astronauts (some listeners and laboratory analysis indicate Grissom) exclaimed "Hey!", "Fire!", or "Flame!"; this was followed by two seconds of scuffling sounds through Grissom's open microphone. This was immediately followed at 6:31:06.2 (23:31:06.2 GMT) by someone (believed by most listeners, and supported by laboratory analysis, to be Chaffee) saying, "[I've, or We've] got a fire in the cockpit." After 6.8 seconds of silence, a second, badly garbled transmission was heard by various listeners as: + "They're fighting a bad fire—Let's get out... Open 'er up", + "We've got a bad fire—Let's get out... We're burning up", or + "I'm reporting a bad fire... I'm getting out..." +The transmission lasted 5.0 seconds and ended with a cry of pain. + +Some blockhouse witnesses said that they saw White on the television monitors, reaching for the inner hatch release handle as flames in the cabin spread from left to right. + +The heat of the fire fed by pure oxygen caused the pressure to rise to , which ruptured the command module's inner wall at 6:31:19 (23:31:19 GMT, initial phase of the fire). Flames and gases then rushed outside the command module through open access panels to two levels of the pad service structure. The intense heat, dense smoke, and ineffective gas masks designed for toxic fumes rather than smoke, hampered the ground crew's attempts to rescue the men. There were fears the command module had exploded, or soon would, and that the fire might ignite the solid fuel rocket in the launch escape tower above the command module, which would have likely killed nearby ground personnel, and possibly have destroyed the pad. + +As the pressure was released by the cabin rupture, the rush of gases within the module caused flames to spread across the cabin, beginning the second phase. The third phase began when most of the oxygen was consumed and was replaced with atmospheric air, essentially quenching the fire, but causing high concentrations of carbon monoxide and heavy smoke to fill the cabin, and large amounts of soot to be deposited on surfaces as they cooled. + +It took five minutes for the pad workers to open all three hatch layers, and they could not drop the inner hatch to the cabin floor as intended, so they pushed it out of the way to one side. Although the cabin lights remained on, they were unable to see the astronauts through the dense smoke. As the smoke cleared they found the bodies, but were not able to remove them. The fire had partly melted Grissom's and White's nylon space suits and the hoses connecting them to the life support system. Grissom had removed his restraints and was lying on the floor of the spacecraft. White's restraints were burned through, and he was found lying sideways just below the hatch. It was determined that he had tried to open the hatch per the emergency procedure, but was not able to do so against the internal pressure. Chaffee was found strapped into his right-hand seat, as procedure called for him to maintain communication until White opened the hatch. Because of the large strands of melted nylon fusing the astronauts to the cabin interior, removing the bodies took nearly 90 minutes. + +Deke Slayton was possibly the first NASA official to examine the spacecraft's interior. His testimony contradicted the official report concerning the position of Grissom's body. Slayton said of Grissom and White's bodies, "it is very difficult for me to determine the exact relationships of these two bodies. They were sort of jumbled together, and I couldn't really tell which head even belonged to which body at that point. I guess the only thing that was real obvious is that both bodies were at the lower edge of the hatch. They were not in the seats. They were almost completely clear of the seat areas." + +Investigation + +As a result of the in-flight failure of the Gemini 8 mission on March 17, 1966, NASA Deputy Administrator Robert Seamans wrote and implemented Management Instruction 8621.1 on April 14, 1966, defining Mission Failure Investigation Policy And Procedures. This modified NASA's existing accident procedures, based on military aircraft accident investigation, by giving the Deputy Administrator the option of performing independent investigations of major failures, beyond those for which the various Program Office officials were normally responsible. It declared, "It is NASA policy to investigate and document the causes of all major mission failures which occur in the conduct of its space and aeronautical activities and to take appropriate corrective actions as a result of the findings and recommendations." + +Immediately after thefire NASA Administrator James E. Webb asked President Lyndon B. Johnson to allow NASA to handle the investigation according to its established procedure, promising to be truthful in assessing blame, and to keep the appropriate leaders of Congress informed. Seamans then directed establishment of the Apollo 204 Review Board chaired by Langley Research Center director Floyd L. Thompson, which included astronaut Frank Borman, spacecraft designer Maxime Faget, and six others. On February 1, Cornell University professor Frank A. Long left the board, and was replaced by Robert W. Van Dolah of the U.S. Bureau of Mines. The next day North American's chief engineer for Apollo, George Jeffs, also left. + +Seamans ordered all Apollo1 hardware and software impounded, to be released only under control of the board. After thorough stereo photographic documentation of the CM-012 interior, the board ordered its disassembly using procedures tested by disassembling the identical CM-014 and conducted a thorough investigation of every part. The board also reviewed the astronauts' autopsy results and interviewed witnesses. Seamans sent Webb weekly status reports of the investigation's progress, and the board issued its final report on April 5, 1967. + +Cause of death +According to the Board, Grissom suffered severe third-degree burns on over one-third of his body and his spacesuit was mostly destroyed. White suffered third-degree burns on almost half of his body and a quarter of his spacesuit had melted away. Chaffee suffered third-degree burns over almost a quarter of his body and a small portion of his spacesuit was damaged. The autopsy report determined that the primary cause of death for all three astronauts was cardiac arrest caused by high concentrations of carbon monoxide. Burns suffered by the crew were not believed to be major factors, and it was concluded that most of them had occurred postmortem. Asphyxiation occurred after the fire melted the astronauts' suits and oxygen tubes, exposing them to the lethal atmosphere of the cabin. + +Major causes of accident +The review board identified several major factors which combined to cause the fire and the astronauts' deaths: + An ignition source most probably related to "vulnerable wiring carrying spacecraft power" and "vulnerable plumbing carrying a combustible and corrosive coolant" + A pure oxygen atmosphere at higher than atmospheric pressure + A cabin sealed with a hatch cover which could not be quickly removed at high pressure + An extensive distribution of combustible materials in the cabin + Inadequate emergency preparedness (rescue or medical assistance, and crew escape) + +Ignition source +The review board determined that the electrical power momentarily failed at 23:30:55 GMT, and found evidence of several electric arcs in the interior equipment. They were unable to conclusively identify a single ignition source. They determined that the fire most likely started near the floor in the lower left section of the cabin, close to the Environmental Control Unit. It spread from the left wall of the cabin to the right, with the floor being affected only briefly. + +The board noted that a silver-plated copper wire, running through an environmental control unit near the center couch, had become stripped of its Teflon insulation and abraded by repeated opening and closing of a small access door. + +This weak point in the wiring also ran near a junction in an ethylene glycol/water cooling line that had been prone to leaks. Electrolysis of ethylene glycol solution with the silver anode of the wire was discovered at the Manned Spacecraft Center on May 29, 1967, to be a hazard capable of causing a violent exothermic reaction, igniting the ethylene glycol mixture in the Command Module's pure oxygen atmosphere. Experiments at the Illinois Institute of Technology confirmed the hazard existed for silver-plated wires, but not for copper-only or nickel-plated copper. In July, ASPO directed both North American and Grumman to ensure no silver or silver-coated electrical contacts existed in the vicinity of possible glycol spills in the Apollo spacecraft. + +Pure oxygen atmosphere + +The plugs-out test had been run to simulate the launch procedure, with the cabin pressurized with pure oxygen at the nominal launch level of , above standard sea level atmospheric pressure. This is more than five times the partial pressure of oxygen in the atmosphere, and provides an environment in which materials not normally considered flammable will be highly flammable and burst into flame. + +The high-pressure oxygen atmosphere was similar to that which had been used successfully in the Mercury and Gemini programs. The pressure before launch was deliberately greater than ambient in order to drive out the nitrogen-containing air and replace it with pure oxygen, and also to seal the plug door hatch cover. During the launch, the pressure would have been gradually reduced to the in-flight level of , providing sufficient oxygen for the astronauts to breathe while reducing the fire risk. The Apollo1 crew had successfully tested this procedure with their spacecraft in the Operations and Checkout Building altitude (vacuum) chamber on October 18 and 19, 1966, and the backup crew of Schirra, Eisele and Cunningham had repeated it on December 30. The investigation board noted that, during these tests, the command module had been fully pressurized with pure oxygen four times, for a total of six hours and fifteen minutes, two and a half hours longer than it had been during the plugs-out test. + +Flammable materials in the cabin +The review board cited "many types and classes of combustible material" close to ignition sources. The NASA crew systems department had installed of Velcro throughout the spacecraft, almost like carpeting. This Velcro was found to be flammable in a high-pressure 100% oxygen environment. Astronaut Buzz Aldrin states in his book Men From Earth that the flammable material had been removed per the crew's August 19 complaints and Joseph Shea's order, but was replaced before the August 26 delivery to Cape Kennedy. + +Hatch design + +The inner hatch cover used a plug door design, sealed by higher pressure inside the cabin than outside. The normal pressure level used for launch ( above ambient) created sufficient force to prevent removing the cover until the excess pressure was vented. Emergency procedure called for Grissom to open the cabin vent valve first, allowing White to remove the cover, but Grissom was prevented from doing this because the valve was located to the left, behind the initial wall of flames. Also, while the system could easily vent the normal pressure, its flow capacity was utterly incapable of handling the rapid increase to caused by the intense heat of the fire. + +North American had originally suggested the hatch open outward and use explosive bolts to blow the hatch in case of emergency, as had been done in Project Mercury. NASA did not agree, arguing the hatch could accidentally open, as it had on Grissom's Liberty Bell 7 flight, so the Manned Spacecraft Center designers rejected the explosive design in favor of a mechanically operated one for the Gemini and Apollo programs. Before the fire, the Apollo astronauts had recommended changing the design to an outward-opening hatch, and this was already slated for inclusion in the Block II command module design. According to Donald K. Slayton's testimony before the House investigation of the accident, this was based on ease of exit for spacewalks and at the end of flight, rather than for emergency exit. + +Emergency preparedness +The board noted that the test planners had failed to identify the test as hazardous; emergency equipment (such as gas masks) were inadequate to handle this type of fire; that fire, rescue, and medical teams were not in attendance; and that the spacecraft work and access areas contained many hindrances to emergency response such as steps, sliding doors, and sharp turns. + +Choice of pure oxygen atmosphere +When designing the Mercury spacecraft, NASA had considered using a nitrogen/oxygen mixture to reduce the fire risk near launch, but rejected it based on a number of considerations. First, a pure oxygen atmosphere is comfortably breathable by humans at , greatly reducing the pressure load on the spacecraft in the vacuum of space. Second, nitrogen used with the in-flight pressure reduction carried the risk of decompression sickness (known as "the bends"). But the decision to eliminate the use of any gas but oxygen was crystalized when a serious accident occurred on April 21, 1960, in which McDonnell Aircraft test pilot G. B. North passed out and was seriously injured when testing a Mercury cabin / spacesuit atmosphere system in a vacuum chamber. The problem was found to be nitrogen-rich (oxygen-poor) air leaking from the cabin into his spacesuit feed. North American Aviation had suggested using an oxygen/nitrogen mixture for Apollo, but NASA overruled this. The pure oxygen design was judged to be safer, less complicated, and lighter in weight. In his monograph Project Apollo: The Tough Decisions, Deputy Administrator Seamans wrote that NASA's worst mistake in engineering judgment was not running a fire test on the command module before the plugs-out test. In the first episode of the 2009 BBC documentary series NASA: Triumph and Tragedy, Jim McDivitt said that NASA had no idea how a 100% oxygen atmosphere would influence burning. Similar remarks by other astronauts were expressed in the 2007 documentary film In the Shadow of the Moon. + +Other oxygen incidents +Several fires in high-oxygen test environments had occurred before the Apollo fire. In 1962, USAF Colonel B. Dean Smith was conducting a test of the Gemini space suit with a colleague in a pure oxygen chamber at Brooks Air Force Base in San Antonio, Texas, when a fire broke out, destroying the chamber. Smith and his partner narrowly escaped. On November 17, 1962, a fire broke out in a chamber at the Navy's Air Crew Equipment Laboratory during a pure oxygen test. The fire was started because a faulty ground wire arced onto nearby insulation. After attempts to extinguish the fire by smothering it, the crew escaped the chamber with minor burns across large parts of their bodies. On February 16, 1965, United States Navy Divers Fred Jackson and John Youmans were killed in a decompression chamber fire at the Experimental Diving Unit in Washington, D.C., shortly after additional oxygen was added to the chamber's atmospheric mix. + +In addition to fires with personnel present, the Apollo Environmental Control System experienced several accidents from 1964 to 1966 due to various hardware malfunctions. Notable is the April 28, 1966 fire, as the subsequent investigation found that several new measures should be taken to avoid fires, including improved selection of materials and that ESC and Command Module circuits have a potential for arcing or short circuits. + +Other oxygen fire occurrences are documented in reports archived in the National Air and Space Museum, such as: + Selection of Space Cabin Atmospheres. Part II: Fire and Blast Hazaards in Space Cabins. (Emanuel M. Roth; Dept of Aeronautics Medicine and Bioastronautics, Lovelace Foundation for Medical Education and Research. c. 1964–1966) + "Fire Prevention in Manned Spacecraft and Test Chamber Oxygen Atmospheres". (Manned Spacecraft Center. NASA General Working Paper 10 063. October 10, 1966) + +Incidents had also occurred in the Soviet space program, but due to the Soviet government's policy of secrecy, these were not disclosed until well after the Apollo1 fire. Cosmonaut Valentin Bondarenko died on March 23, 1961, from burns sustained in a fire while participating in a 15-day endurance experiment in a high-oxygen isolation chamber, less than three weeks before the first Vostok crewed space flight; this was disclosed on January 28, 1986. + +During the Voskhod 2 mission in March 1965, cosmonauts Pavel Belyayev and Alexei Leonov could not completely seal the spacecraft hatch after Leonov's historic first walk in space. The spacecraft's environmental control system responded to the leaking air by adding more oxygen to the cabin, causing the concentration level to rise as high as 45%. The crew and ground controllers worried about the possibility of fire, remembering Bondarenko's death four years earlier. + +On January 31, 1967, four days after the Apollo1 fire, United States Air Force airmen William F. Bartley Jr. and Richard G. Harmon were killed in a flash fire while tending laboratory rabbits in the Two Man Space Environment Simulator, a pure oxygen chamber at the School of Aerospace Medicine at Brooks Air Force Base. Like the Apollo1 fire, the School fire was caused by an electrical spark in a pure oxygen environment. The widows of the Apollo1 crew sent condolence letters to Bartley and Harmon's families. + +Political fallout + +Committees in both houses of the United States Congress with oversight of the space program soon launched investigations, including the Senate Committee on Aeronautical and Space Sciences, chaired by Senator Clinton P. Anderson. Seamans, Webb, Manned Space Flight Administrator Dr. George E. Mueller, and Apollo Program Director Maj Gen Samuel C. Phillips were called to testify before Anderson's committee. + +In the February 27 hearing, Senator Walter F. Mondale asked Webb if he knew of a report of extraordinary problems with the performance of North American Aviation on the Apollo contract. Webb replied he did not, and deferred to his subordinates on the witness panel. Mueller and Phillips responded they too were unaware of any such "report". + +However, in late 1965, just over a year before the accident, Phillips had headed a "tiger team" investigating the causes of inadequate quality, schedule delays, and cost overruns in both the Apollo CSM and the Saturn V second stage (for which North American was also prime contractor). He gave an oral presentation (with transparencies) of his team's findings to Mueller and Seamans, and also presented them in a memo to North American president John L. Atwood, to which Mueller appended his own strongly worded memo to Atwood. + +During Mondale's 1967 questioning about what was to become known as the "Phillips Report", Seamans was afraid Mondale might actually have seen a hard copy of Phillips' presentation, and responded that contractors have occasionally been subjected to on-site progress reviews; perhaps this was what Mondale's information referred to. Mondale continued to refer to "the Report" despite Phillips' refusal to characterize it as such, and, angered by what he perceived as Webb's deception and concealment of important program problems from Congress, he questioned NASA's selection of North American as prime contractor. Seamans later wrote that Webb roundly chastised him in the cab ride leaving the hearing, for volunteering information which led to the disclosure of Phillips' memo. + +On May 11, Webb issued a statement defending NASA's November 1961 selection of North American as the prime contractor for Apollo. This was followed on June9 by Seamans filing a seven-page memorandum documenting the selection process. Webb eventually provided a controlled copy of Phillips' memo to Congress. The Senate committee noted in its final report NASA's testimony that "the findings of the [Phillips] task force had no effect on the accident, did not lead to the accident, and were not related to the accident", but stated in its recommendations: + +Freshman Senators Edward W. Brooke III and Charles H. Percy jointly wrote an Additional Views section appended to the committee report, chastising NASA more strongly than Anderson for not having disclosed the Phillips review to Congress. Mondale wrote his own, even more strongly worded Additional View, accusing NASA of "evasiveness,... lack of candor,... patronizing attitude toward Congress... refusal to respond fully and forthrightly to legitimate Congressional inquiries, and... solicitous concern for corporate sensitivities at a time of national tragedy". + +The potential political threat to Apollo blew over, due in large part to the support of President Lyndon B. Johnson, who at the time still wielded a measure of influence with the Congress from his own Senatorial experience. He was a staunch supporter of NASA since its inception, had even recommended the Moon program to President John F. Kennedy in 1961, and was skilled at portraying it as part of Kennedy's legacy. + +Relations between NASA and North American deteriorated over the assignment of blame. North American argued unsuccessfully it was not responsible for the fatal error in spacecraft atmosphere design. Finally, Webb contacted Atwood, and demanded either he or Chief Engineer Harrison A. Storms resign. Atwood elected to fire Storms. + +On the NASA side, Joseph Shea resorted to barbiturates and alcohol in order to help him cope. NASA administrator James Webb became increasingly worried about Shea's mental state. Shea was asked to take an extended voluntary leave of absence, but Shea refused, threatening to resign rather than take leave. As a compromise, he agreed to meet with a psychiatrist and to abide by an independent assessment of his psychological fitness. This approach to remove Shea from his position was also unsuccessful. Finally, six months after the fire, Shea's superiors reassigned him to NASA headquarters in Washington, D.C. Shea felt that his new post was a "non-job," and left after only two months. + +Program recovery + +Gene Kranz called a meeting of his staff in Mission Control three days after the accident, delivering a speech which has subsequently become one of NASA's principles. Speaking of the errors and overall attitude surrounding the Apollo program before the accident, he said: "We were too 'gung-ho' about the schedule and we blocked out all of the problems we saw each day in our work. Every element of the program was in trouble and so were we." He reminded the team of the perils and mercilessness of their endeavor, and stated the new requirement that every member of every team in mission control be "tough and competent", requiring nothing less than perfection throughout NASA's programs. In 2003, following the Space Shuttle Columbia disaster, NASA administrator Sean O'Keefe quoted Kranz's speech, applying it to the Columbia crew. + +Command module redesign +After the fire, the Apollo program was grounded for review and redesign. The command module was found to be extremely hazardous and, in some instances, carelessly assembled (for example, a misplaced wrench socket was found in the cabin). + +It was decided that the remaining Block I spacecraft would be used only for uncrewed Saturn V test flights. All crewed missions would use the Block II spacecraft, to which many command module design changes were made: + The cabin atmosphere at launch was adjusted to 60% oxygen and 40% nitrogen at sea-level pressure: . During ascent the cabin rapidly vented down to , releasing approximately 2/3 of the gas originally present at launch. The vent then closed and the environmental control system maintained a nominal cabin pressure of as the spacecraft continued into vacuum. The cabin was then very slowly purged (vented to space and simultaneously replaced with 100% oxygen), so the nitrogen concentration gradually fell off to zero over the next day. Although the new cabin launch atmosphere was significantly safer than 100% oxygen, it still contained almost three times the amount of oxygen present in ordinary sea-level air (20.9% oxygen). This was necessary to ensure a sufficient partial pressure of oxygen when the astronauts removed their helmets after reaching orbit. (60% of five psi is three psi, compared to 60% of which is at launch, and 20.9% of which is in sea-level air.) + The environment within the astronauts' pressure suits was not changed. Because of the rapid drop in cabin (and suit) pressures during ascent, decompression sickness was likely unless the nitrogen had been purged from the astronauts' tissues before launch. They would still breathe pure oxygen, starting several hours before launch, until they removed their helmets on orbit. Avoiding the "bends" was considered worth the residual risk of an oxygen-accelerated fire within a suit. + Nylon used in the Block I suits was replaced in the Block II suits with Beta cloth, a non-flammable, highly melt-resistant fabric woven from fiberglass and coated with Teflon. + Block II had already been planned to use a completely redesigned hatch which opened outward, and could be opened in less than five seconds. Concerns of accidental opening were addressed by using a cartridge of pressurized nitrogen to drive the release mechanism in an emergency, instead of the explosive bolts used on Project Mercury. + Flammable materials in the cabin were replaced with self-extinguishing versions. + Plumbing and wiring were covered with protective insulation. Aluminum tubing was replaced with stainless steel tubing that used brazed joints when possible. + +Thorough protocols were implemented for documenting spacecraft construction and maintenance. + +New mission naming scheme +The astronauts' widows asked that Apollo 1 be reserved for the flight their husbands never made, and on April 24, 1967, Mueller, as Associate Administrator for Manned Space Flight, announced this change officially: AS-204 would be recorded as Apollo1, "first manned Apollo Saturn flight – failed on ground test". Even though three uncrewed Apollo missions (AS-201, AS-202, and AS-203) had previously occurred, only AS-201 and AS-202 carried spacecraft. Therefore, the next mission, the first uncrewed Saturn V test flight (AS-501) would be designated Apollo4, with all subsequent flights numbered sequentially in the order flown. The first three flights would not be renumbered, and the names Apollo2 and Apollo3 would officially go unused. Mueller considered AS-201 and AS-202, the first and second flights of the Apollo Block I CSM, as Apollo2 and3 respectively. + +The crewed flight hiatus allowed work to catch up on the Saturn V and lunar module, which were encountering their own delays. Apollo4 flew in November 1967. Apollo1's (AS-204) Saturn IB rocket was taken down from Launch Complex 34, later reassembled at Launch complex 37B and used to launch Apollo5, an uncrewed Earth orbital test flight of the first lunar module, LM-1, in January 1968. A second uncrewed Saturn V AS-502 flew as Apollo6 in April 1968, and Grissom's backup crew of Wally Schirra, Don Eisele, and Walter Cunningham, finally flew the orbital test mission as Apollo7 (AS-205), in a Block II CSM in October 1968. + +Memorials + +Gus Grissom and Roger Chaffee were buried at Arlington National Cemetery. Ed White was buried at West Point Cemetery on the grounds of the United States Military Academy in West Point, New York. NASA officials attempted to pressure Pat White, Ed White's widow, into allowing her husband also to be buried at Arlington, against what she knew to be his wishes; their efforts were foiled by astronaut Frank Borman. The names of the Apollo 1 crew are among those of multiple astronauts who have died in the line of duty, listed on the Space Mirror Memorial at the Kennedy Space Center Visitor Complex in Merritt Island, Florida. President Jimmy Carter awarded the Congressional Space Medal of Honor posthumously to Grissom on October 1, 1978. President Bill Clinton awarded it to White and Chaffee on December 17, 1997. + +An Apollo 1 mission patch was left on the Moon's surface after the first crewed lunar landing by Apollo11 crew members Neil Armstrong and Buzz Aldrin. The Apollo15 mission left on the surface of the Moon a tiny memorial statue, Fallen Astronaut, along with a plaque containing the names of the Apollo1 astronauts, among others including Soviet cosmonauts, who perished in the pursuit of human space flight. + +Launch Complex 34 + +After the Apollo 1 fire, Launch Complex 34 was subsequently used only for the launch of Apollo7 and later dismantled down to the concrete launch pedestal, which remains at the site () along with a few other concrete and steel-reinforced structures. The pedestal bears two plaques commemorating the crew. +The "Ad Astra per aspera" plaque for "the crew of Apollo 1" is seen in the 1998 film Armageddon. +The "Dedicated to the living memory of the crew of the Apollo 1" plaque is quoted at the end of Wayne Hale's Requiem for the NASA Space Shuttle program. Each year the families of the Apollo1 crew are invited to the site for a memorial, and the Kennedy Space Center Visitor Complex includes the site during the tour of the historic Cape Canaveral launch sites. + +In January 2005, three granite benches, built by a college classmate of one of the astronauts, were installed at the site on the southern edge of the launch pad. Each bears the name of one of the astronauts and his military service insignia. + +Stars, landmarks on the Moon and Mars + Apollo astronauts frequently aligned their spacecraft inertial navigation platforms and determined their positions relative to the Earth and Moon by sighting sets of stars with optical instruments. As a practical joke, the Apollo1 crew named three of the stars in the Apollo catalog after themselves and introduced them into NASA documentation. Gamma Cassiopeiae became Navi – Ivan (Gus Grissom's middle name) spelled backwards. Iota Ursae Majoris became Dnoces – "Second" spelled backwards, for Edward H. White II. And Gamma Velorum became Regor – Roger (Chaffee) spelled backwards. These names quickly stuck after the Apollo1 accident and were regularly used by later Apollo crews. + Craters on the Moon and hills on Mars are named after the three Apollo1 astronauts. + +Civic and other memorials + Three public schools in Huntsville, Alabama (home of George C. Marshall Space Flight Center and the U.S. Space & Rocket Center): Virgil I. Grissom High School, Ed White Middle School, and the Chaffee Elementary School. + Ed White II Elementary e-STEM (Elementary-Science, Technology, Engineering and Math) Magnet school in El Lago, Texas, near the Johnson Space Center. White lived in El Lago (next door to Neil Armstrong). + There are Grissom or Virgil I. Grissom middle schools in Mishawaka, Indiana, Sterling Heights, Michigan, and Tinley Park, Illinois. + Virgil Grissom Elementary School in Princeton, Iowa, and the Edward White Elementary School in Eldridge, Iowa, are both part of the North Scott Community School District also naming the other three elementary schools after astronauts Neil Armstrong, John Glenn, and Alan Shepard. + School #7 in Rochester, New York, is also known as the Virgil I. Grissom School. + In the early 1970s, three streets in Amherst, New York, were named for Chaffee, White and Grissom. By 1991, when no homes had been built on Grissom Drive, the area was repurposed as commercial property; the Grissom street sign was removed and the street renamed Classics V Drive for the banquet hall that occupied the land. + The THUMS Islands, four man-made oil drilling islands in the harbor off Long Beach, California, are named Grissom, White, Chaffee and Theodore Freeman. + The Roger B. Chaffee Planetarium is located at the Grand Rapids Public Museum. + Roger B. Chaffee Memorial Boulevard in Wyoming, Michigan, the largest suburb of Grand Rapids, Michigan, which is today an industrial park, but exists on the site of the former Grand Rapids Airport. A large portion of the north-south runway is used today as the roadway of the Roger B. Chaffee Memorial Boulevard. + Roger B. Chaffee Scholarship Fund in Grand Rapids, Michigan, each year in memory of Chaffee honors one student who intends to pursue a career in engineering or the sciences + Three adjacent parks in Fullerton, California, are each named for Grissom, Chaffee and White. The parks are located near a former Hughes Aircraft research and development facility. A Hughes subsidiary, Hughes Space and Communications Company, built components for the Apollo program. + Two buildings on the campus of Purdue University in West Lafayette, Indiana, are named for Grissom and Chaffee (both Purdue alumni). Grissom Hall houses the School of Industrial Engineering (and was home to the School of Aeronautics and Astronautics before it moved into the new Neil Armstrong Hall of Engineering). Chaffee Hall, constructed in 1965, is the administration complex of Maurice J. Zucrow Laboratories where combustion, propulsion, gas dynamics, and related fields are studied. The Chaffee Hall contains a 72-seat auditorium, offices, and administrative staff. + A tree for each astronaut was planted in NASA's Astronaut Memorial Grove at the Johnson Space Center in Houston, Texas, not far from the Saturn V building, along with trees for each astronaut from the Challenger and Columbia disasters. Tours of the space center pause briefly near the grove for a moment of silence, and the trees can be seen from nearby NASA Road 1. + In 1968, Bunker Hill Air Force Base near Peru, Indiana was renamed Grissom Air Force Base. The three-letter code for the VOR air navigation beacon at the base is GUS. + +Remains of CM-012 + +The Apollo 1 command module has never been on public display. After the accident, the spacecraft was removed and taken to Kennedy Space Center to facilitate the review board's disassembly in order to investigate the cause of the fire. When the investigation was complete, it was moved to the NASA Langley Research Center in Hampton, Virginia, and placed in a secured storage warehouse. +On February 17, 2007, the parts of CM-012 were moved approximately to a newer, environmentally controlled warehouse. Only a few weeks earlier, Gus Grissom's brother Lowell publicly suggested CM-012 be permanently entombed in the concrete remains of Launch Complex 34. + +On January 27, 2017, the 50th anniversary of the fire, NASA put the hatch from Apollo1 on display at the Saturn V Rocket Center at Kennedy Space Center Visitors Complex. KSC's Visitor Complex also houses memorials that include parts of Challenger and Columbia, located in the Space Shuttle Atlantis exhibit. "This is way, way, way long overdue.

NASA, the mission's operator, described it as a "dress rehearsal" for the first Moon landing (Apollo 11, two months later). It was designated an "F"mission, intended to test all spacecraft components and procedures short of actual descent and landing. + +After the spacecraft reached lunar orbit, astronaut John Young remained in the Command and Service Module (CSM) while astronauts Thomas Stafford and Gene Cernan flew the Apollo Lunar Module (LM) to within of the lunar surface, the point at which powered descent for landing would begin on a landing mission. Then they rejoined Young in the CSM and, after the CSM completed its 31st orbit of the Moon, they returned safely to Earth. + +While NASA had considered attempting the first crewed lunar landing on Apollo 10, mission planners ultimately decided that it would be prudent to have a practice flight to hone the procedures and techniques. The crew encountered some problems during the flight: pogo oscillations during the launch phase and a brief, uncontrolled tumble of the LM ascent stage in lunar orbit during its solo flight. However, the mission accomplished its major objectives. Stafford and Cernan observed and photographed Apollo 11's planned landing site in the Sea of Tranquility. Apollo 10 spent 61 hours and 37 minutes orbiting the Moon, for about eight hours of which Stafford and Cernan flew the LM apart from Young in the CSM, and about eight days total in space. Additionally, Apollo 10 set the record for the highest speed attained by a crewed vehicle: 39,897 km/h (11.08 km/s or 24,791 mph) on May 26, 1969, during the return from the Moon. + +The mission's call signs were the names of the Peanuts characters Charlie Brown for the CSM and Snoopy for the LM, who became Apollo 10's semi-official mascots. Peanuts creator Charles Schulz also drew mission-related artwork for NASA. + +Framework + +Background + +By 1967, NASA had devised a list of mission types, designated by letters, that needed to be flown before a landing attempt, which would be the "G" mission. The early uncrewed flights were considered "A" or "B" missions, while Apollo 7, the crewed-flight test of the Command and Service Module (CSM), was the "C" mission. The first crewed orbital test of the Lunar Module (LM) was accomplished on Apollo 9, the "D" mission. Apollo 8, flown to the Moon's orbit without an LM, was considered a "C-prime" mission, but its success gave NASA the confidence to skip the "E" mission, which would have tested the full Apollo spacecraft in medium or high Earth orbit. Apollo 10, the dress rehearsal for the lunar landing, was to be the "F" mission. + +NASA considered skipping the "F" mission as well and attempting the first lunar landing on Apollo 10. Some with the agency advocated this, feeling it senseless to bring astronauts so close to the lunar surface, only to turn away. Although the lunar module intended for Apollo 10 was too heavy to perform the lunar mission, the one intended for Apollo 11 could be substituted by delaying Apollo 10 a month from its May 1969 planned launch. NASA official George Mueller favored a landing attempt on ; he was known for his aggressive approach to moving the Apollo program forward. However, Director of Flight Operations Christopher C. Kraft and others opposed this, feeling that new procedures would have to be developed for a rendezvous in lunar orbit and that NASA had incomplete information regarding the Moon's mass concentrations, which might throw off the spacecraft's trajectory. Lieutenant General Sam Phillips, the Apollo Program Manager, listened to the arguments on both sides and decided that having a dress rehearsal was crucial. + +Crew and key Mission Control personnel + +On November 13, 1968, NASA announced the crew members of Apollo 10. Thomas P. Stafford, the commander, was 38 years old at the time of the mission. A 1952 graduate of the Naval Academy, he was commissioned in the Air Force. Selected for the second group of astronauts in 1962, he flew as pilot of Gemini 6A (1965) and command pilot of Gemini 9A (1966). John Young, the command module pilot, was 38 years old and a commander in the Navy at the time of Apollo 10. A 1952 graduate of Georgia Tech who entered the Navy after graduation and became a test pilot in 1959, he was selected as a Group 2 astronaut alongside Stafford. He flew in Gemini 3 with Gus Grissom in 1965, becoming the first American not of the Mercury Seven to fly in space. Young thereafter commanded Gemini 10 (1966), flying with Michael Collins. Eugene Cernan, the lunar module pilot, was a commander in the Navy at the time of Apollo 10. A 1952 graduate of Purdue University, he entered the Navy after graduation. Selected for the third group of astronauts in 1963, Cernan flew with Stafford on Gemini 9A before his assignment to Apollo 10. With five prior flights among them, the Apollo 10 crew was the most experienced to reach space until the Space Shuttle era, and the first American space mission whose crew were all spaceflight veterans. + +The backup crew for Apollo 10 was L. Gordon Cooper Jr as commander, Donn F. Eisele as command module pilot, and Edgar D. Mitchell as lunar module pilot. By the normal crew rotation in place during Apollo, Cooper, Eisele, and Mitchell would have flown on Apollo 13, but Cooper and Eisele never flew again. Deke Slayton, Director of Flight Crew Operations, felt that Cooper did not train as hard as he could have. Eisele was blackballed because of incidents during Apollo 7, which he had flown as CMP and which had seen conflict between the crew and ground controllers; he had also been involved in a messy divorce. Slayton only assigned the two as backups because he had few veteran astronauts available. Cooper and Eisele were replaced by Alan Shepard and Stuart Roosa respectively. Feeling they needed additional training time, George Mueller rejected the Apollo 13 crew. The crew was switched to Apollo 14, which saw Shepard and Mitchell walk on the Moon. + +For projects Mercury and Gemini, a prime and a backup crew had been designated, but for Apollo, a third group of astronauts, known as the support crew, was also designated. Slayton created the support crews early in the Apollo program on the advice of McDivitt, who would lead Apollo 9. McDivitt believed that, with preparation going on in facilities across the U.S., meetings that needed a member of the flight crew would be missed. Support crew members were to assist as directed by the mission commander. Usually low in seniority, they assembled the mission's rules, flight plan, and checklists, and kept them updated. For Apollo 10, they were Joe Engle, James Irwin, and Charles Duke. + +Flight directors were Gerry Griffin, Glynn Lunney, Milt Windler, and Pete Frank. Flight directors during Apollo had a one-sentence job description: "The flight director may take any actions necessary for crew safety and mission success." CAPCOMs were Duke, Engle, Jack Lousma, and Bruce McCandless II. + +Call signs and mission insignia + +The command module was given the call sign "Charlie Brown" and the lunar module the call sign "Snoopy". These were taken from the characters in the comic strip, Peanuts, Charlie Brown and Snoopy. These names were chosen by the astronauts with the approval of Charles Schulz, the strip's creator, who was uncertain it was a good idea, since Charlie Brown was always a failure. The choice of names was deemed undignified by some at NASA, as were the choices for Apollo 9's CM and LM ("Gumdrop" and "Spider"). Public relations chief Julian Scheer urged a change for the lunar landing mission. But for Apollo 10, according to Cernan, "The P.R.-types lost this one big-time, for everybody on the planet knew the klutzy kid and his adventuresome beagle, and the names were embraced in a public relations bonanza." Apollo 11's call signs were "Columbia" for the command module and "Eagle" for the lunar module. + +Snoopy, Charlie Brown's dog, was chosen for the call sign of the lunar module since it was to "snoop" around the landing site, with Charlie Brown given to the command module as Snoopy's companion. Snoopy had been associated for some time with the space program, with workers who performed in an outstanding manner awarded silver "Snoopy pins", and Snoopy posters were seen at NASA facilities, with the cartoon dog having traded in his World War I aviator's headgear for a space helmet. Stafford stated that, given the pins, "the choice of Snoopy [as call sign] was a way of acknowledging the contributions of the hundreds of thousands of people who got us there". The use of the dog was also appropriate since, in the comic strip, Snoopy had journeyed to the Moon the year before, thus defeating, according to Schulz, "the Americans, the Russians, and that stupid cat next door". + +The shield-shaped mission insignia shows a large, three-dimensional Roman numeral X sitting on the Moon's surface, in Stafford's words, "to show that we had left our mark". Although it did not land on the Moon, the prominence of the number represents the contributions the mission made to the Apollo program. A CSM circles the Moon as an LM ascent stage flies up from its low pass over the lunar surface with its engine firing. The Earth is visible in the background. On the mission patch, a wide, light blue border carries the word APOLLO at the top and the crew names around the bottom. The patch is trimmed in gold. The insignia was designed by Allen Stevens of Rockwell International. + +Training and preparation + +Apollo 10, the "F" mission or dress rehearsal for the lunar landing, had as its primary objectives to demonstrate crew, space vehicle and mission support facilities performance during a crewed mission to lunar orbit, and to evaluate the performance of the lunar module there. In addition, it was to attempt photography of Apollo Landing Site 2 (ALS-2) in the Sea of Tranquillity, the contemplated landing site for Apollo 11. According to Stafford, Our flight was to take the first lunar module to the moon. We would take the lunar module, go down to within about ten miles above the moon, nine miles above the mountains, radar map, photo map, pick out the first landing site, do the first rendezvous around the moon, pick out some future landing sites, and come home. + +Apollo 10 was to adhere as closely as possible to the plans for Apollo 11, including its trajectory to and from lunar orbit, the timeline of mission events, and even the angle of the Sun at ALS-2. However, no landing was to be attempted. ALS-1, given that number because it was the furthest to the east of the candidate sites, and also located in the Sea of Tranquility, had been extensively photographed by Apollo 8 astronauts; at the suggestion of scientist-astronaut Harrison Schmitt, the launch of Apollo 10 had been postponed a day so ALS-2 could be photographed under proper conditions. ALS-2 was chosen as the lunar landing site since it was relatively smooth, of scientific interest, and ALS-1 was deemed too far to the east. Thus, when Apollo 10's launch date was announced on January 10, 1969, it was shifted from its placeholder date of May 1 to May 17, rather than to May 16. On March 17, 1969, the launch was slipped one day to May 18, to allow for a better view of ALS-3, to the west of ALS-2. Another deviation from the plans for Apollo 11 was that Apollo 10 was to spend an additional day in lunar orbit once the CSM and LM rendezvoused; this was to allow time for additional testing of the LM's systems, as well as for photography of possible future Apollo landing sites. + +The Apollo 10 astronauts undertook five hours of formal training for each hour of the mission's eight-day duration. This was in addition to the normal mission preparations such as technical briefings, pilot meetings and study. They took part in the testing of the CSM at the Downey, California, facility of its manufacturer, North American Rockwell, and of the LM at Grumman in Bethpage, New York. They visited Cambridge, Massachusetts, for briefings on the Apollo Guidance Computer at the Massachusetts Institute of Technology Instrumentation Laboratory. They each spent more than 300 hours in simulators of the CM or LM at the Manned Spacecraft Center (MSC) in Houston and at Kennedy Space Center (KSC) in Florida. To train for the high-acceleration conditions they would experience in returning to Earth's atmosphere, they endured MSC's centrifuge. + +Lunar landing capability + +While Apollo 10 was meant to follow the procedures of a lunar landing mission to the point of powered descent, Apollo 10's LM was not capable of landing and returning to lunar orbit. The ascent stage was loaded with the amount of fuel and oxidizer it would have had remaining if it had lifted off from the surface and reached the altitude at which the Apollo 10 ascent stage fired; this was only about half the total amount required for lift off and rendezvous with the CSM. The mission-loaded LM weighed , compared to for the Apollo 11 LM which made the first landing. Additionally, the software necessary to guide the LM to a landing was not available at the time of Apollo 10. + +Craig Nelson wrote in his book Rocket Men that NASA took special precaution to ensure Stafford and Cernan would not attempt to make the first landing. Nelson quoted Cernan as saying "A lot of people thought about the kind of people we were: 'Don't give those guys an opportunity to land, 'cause they might!' So the ascent module, the part we lifted off the lunar surface with, was short-fueled. The fuel tanks weren't full. So had we literally tried to land on the Moon, we couldn't have gotten off." Mueller, NASA's Associate Administrator for Manned Space Flight, stated, There had been some speculation about whether or not the crew might have landed, having gotten so close. They might have wanted to, but it was impossible for that lunar module to land. It was an early design that was too heavy for a lunar landing, or, to be more precise, too heavy to be able to complete the ascent back to the command module. It was a test module, for the dress rehearsal only, and that was the way it was used. + +Equipment +The descent stage of the LM was delivered to KSC on October 11, 1968, and the ascent stage arrived five days later. They were mated on November 2. The Service Module (SM) and Command Module (CM) arrived on November 24 and were mated two days later. Portions of the Saturn V launch vehicle arrived during November and December 1968, and the complete launch vehicle was erected in the Vehicle Assembly Building (VAB) on December 30. After being tested in an altitude chamber, the CSM was placed atop the launch vehicle on February 6, 1969. The completed space vehicle was rolled out to Launch Complex 39B on March 11, 1969—the fact that it had been assembled in the VAB's High Bay 2 (the first time it had been used) required the crawler to exit the rear of the VAB before looping around the building and joining the main crawlerway, proceeding to the launch pad. This rollout, using Mobile Launch Platform-3 (MLP-3), happened eight days after the launch of Apollo 9, while that mission was still in orbit. + +The launch vehicle for Apollo 10 was a Saturn V, designated AS-505, the fifth flight-ready Saturn V to be launched and the third to take astronauts to orbit. The Saturn V differed from that used on Apollo 9 in having a lower dry weight (without propellant) in its first two stages, with a significant reduction to the interstage joining them. Although the S-IVB third stage was slightly heavier, all three stages could carry a greater weight of propellant, and the S-II second stage generated more thrust than that of Apollo 9. + +The Apollo spacecraft for the Apollo 10 mission was composed of Command Module 106 (CM-106), Service Module 106 (SM-106, together with the CM known as CSM-106), Lunar Module 4 (LM-4), a spacecraft-lunar module adapter (SLA), numbered as SLA-13A, and a launch escape system. The SLA was a mating structure joining the Instrument Unit on the S-IVB stage of the Saturn V launch vehicle and the CSM, and acted as a housing for the LM, while the Launch Escape System (LES) contained rockets to propel the CM to safety if there was an aborted launch. At about 76.99 metric tons, Apollo 10 would be the heaviest spacecraft to reach orbit to that point. + +Mission highlights + +Launch and outbound trip +Apollo 10 launched from KSC on May 18, 1969, at 12:49:00 EDT (16:49:00 UT), at the start of a 4.5-hour launch window. The launch window was timed to secure optimal lighting conditions at Apollo Landing Site 2 at the time of the LM's closest approach to the site days later. The launch followed a countdown that had begun at 21:00:00 EDT on May 16 (01:00:00 UT on May 17). Because preparations for Apollo 11 had already begun at Pad 39A, Apollo 10 launched from Pad 39B, becoming the only Apollo flight to launch from that pad and the only one to be controlled from its Firing Room 3. + +Problems that arose during the countdown were dealt with during the built-in holds, and did not delay the mission. On the day before launch, Cernan had been stopped for speeding while returning from a final visit with his wife and child. Lacking identification and under orders to tell no one who he was, Cernan later attested in his autobiography that he had feared being arrested. Launch pad leader Gunther Wendt, who had pulled over nearby after recognizing Cernan, explained the situation to the police officer, who then released Cernan despite the officer's skepticism that Cernan was an astronaut. + +The crew experienced a somewhat rough ride on the way to orbit due to pogo oscillations. About 12 minutes after liftoff, the spacecraft entered a low Earth orbit with a high point of and a low point of . All appeared to be normal during the systems review period in Earth orbit, and the crew restarted the S-IVB third stage to achieve trans-lunar injection (TLI) and send them towards the Moon. The vehicle shook again while executing the TLI burn, causing Cernan to be concerned that they might have to abort. However, the TLI burn was completed without incident. Young then performed the transposition, docking, and extraction maneuver, separating the CSM from the S-IVB stage, turning around, and docking its nose to the top of the lunar module (LM), before separating from the S-IVB. Apollo 10 was the first mission to carry a color television camera inside the spacecraft, and mission controllers in Houston watched as Young performed the maneuver. Soon thereafter, the large television audience was treated to color views of the Earth. One problem that was encountered was that the mylar cover of the CM's hatch had pulled loose, spilling quantities of fiberglass insulation into the tunnel, and then into both the CM and LM. The S-IVB was fired by ground command and sent into solar orbit with a period of 344.88 days. + +The crew settled in for the voyage to the Moon. They had a light workload, and spent much of their time studying the flight plan or sleeping. They made five more television broadcasts back to Earth, and were informed that more than a billion people had watched some part of their activities. In June 1969, the crew would accept a special Emmy Award on behalf of the first four Apollo crews for their television broadcasts from space. One slight course correction was necessary; this occurred at 26:32:56.8 into the mission and lasted 7.1 seconds. This aligned Apollo 10 with the trajectory Apollo 11 was expected to take. One issue the crew encountered was bad-tasting food, as Stafford apparently used a double dose of chlorine in their drinking water, which had to be placed in their dehydrated food to reconstitute it. + +Lunar orbit + +Arrival and initial operations +At 75:55:54 into the mission, above the far side of the Moon, the CSM's service propulsion system (SPS) engine was fired for 356.1 seconds to slow the spacecraft into a lunar orbit of . This was followed, after two orbits of the Moon, with a 13.9-second firing of the SPS to circularize the orbit to at 80:25:08.1. Within the first couple of hours after the initial lunar orbit insertion burn and following the circularization burn, the crew turned to tracking planned landmarks on the surface below to record observations and take photographs. In addition to ALS-1, ALS-2, and ALS-3, the crew of Apollo 10 observed and photographed features on the near and far sides of the Moon, including the craters Coriolis, King, and Papaleksi. Shortly after the circularization burn, the crew partook in a scheduled half-hour color-television broadcast with descriptions and video transmissions of views of the lunar surface below. + +About an hour after the second burn, the LM crew of Stafford and Cernan entered the LM to check out its systems. They were met with a blizzard of fiberglass particles from the earlier problem, which they cleaned up with a vacuum cleaner as best they could. Stafford had to help Cernan remove smaller bits from his hair and eyebrows. Stafford later commented that Cernan looked like he just came out of a chicken coop, and that the particles made them itch and got into the air conditioning system, and they were scraping it off the filter screens for the rest of the mission. This was merely an annoyance, but the particles may have gotten into the docking ring joining the two craft and caused it to misalign slightly. Mission Control determined that this was still within safe limits. + +The flight of Snoopy + +After Stafford and Cernan checked out Snoopy, they returned to Charlie Brown for a rest. Then they re-entered Snoopy and undocked it from the CSM at 98:29:20. Young, who remained in the CSM, became the first person to fly solo in lunar orbit. After undocking, Stafford and Cernan deployed the LM's landing gear and inspected the LM's systems. The CSM performed an 8.3-second burn with its RCS thrusters to separate itself from the LM by about 30 feet, after which Young visually inspected the LM from the CSM. The CSM performed another separation burn, this time separating the two spacecraft by about . The LM crew then performed the descent orbit insertion maneuver by firing their descent engine for 27.4 seconds at 99:46:01.6, and tested their craft's landing radar as they approached the altitude where the subsequent Apollo 11 mission would begin powered descent to land on the Moon. Previously, the LM's landing radar had only been tested under terrestrial conditions. While the LM executed these maneuvers, Young monitored the location and status of the LM from the CSM, standing by to rescue the LM crew if necessary. Cernan and Stafford surveyed ALS-2, coming within of the surface at a point 15 degrees to its east, then performed a phasing burn at 100:58:25.93, thrusting for just under 40 seconds to allow a second pass at ALS-2, when the craft came within of the Moon, its closest approach. Reporting on his observations of the site from the LM's low passes, Stafford indicated that ALS-2 seemed smoother than he had expected and described its appearance as similar to the desert surrounding Blythe, California; but he observed that Apollo 11 could face rougher terrain downrange if it approached off-target. Based upon Apollo 10's observations from relatively low altitude, NASA mission planners became comfortable enough with ALS-2 to confirm it as the target site for Apollo 11. + +The next action was to prepare to separate the LM ascent stage from the descent stage, to jettison the descent stage, and fire the Ascent Propulsion System to return the ascent stage towards the CSM. As Stafford and Cernan prepared to do so, the LM began to gyrate out of control. Alarmed, Cernan exclaimed, "Son of a bitch!" into a hot mic being broadcast live, which, combined with other language used by the crew during the mission, generated some complaints back on Earth. Stafford discarded the descent stage about five seconds after the tumbling began and fought to regain control manually, suspecting that there might have been an "open thruster", or a thruster stuck firing. He did so in time to orient the spacecraft to rejoin Charlie Brown. The problem was traced to a switch controlling the mode of the abort guidance system; it was to be moved as part of the procedure, but both of the crew members switched it, thus returning it to the original position. Had they fired Snoopy in the wrong direction, they might have missed the rendezvous with Charlie Brown or crashed into the Moon. Once Stafford had regained control of the LM ascent stage, which took about eight seconds, the pair fired the ascent engine at the lowest point of the LM's orbit, mimicking the orbital insertion maneuver after launch from the lunar surface in a later landing mission. Snoopy coasted on that trajectory for about an hour before firing the engine once more to further fine-tune its approach to Charlie Brown. + +Snoopy rendezvoused with and re-docked with Charlie Brown at 106:22:02, just under eight hours after undocking. The docking was telecast live in color from the CSM. Once Cernan and Stafford had re-entered Charlie Brown, Snoopy was sealed off and separated from Charlie Brown. The rest of the LM's ascent-stage engine fuel was burned to send it on a trajectory past the Moon and into a heliocentric orbit. + +It was the only Apollo LM to meet this fate; the Apollo 11 ascent stage would be left in lunar orbit to crash, while post-Apollo 11 ascent stages were steered into the Moon to obtain readings from seismometers placed on the surface, except for Apollo 13's ascent stage, which the crew used as a "life boat" to get safely back to Earth before releasing it to burn up in Earth's atmosphere, and Apollo 16's, which NASA lost control of after jettison. + +Return to Earth + +After ejecting the LM ascent stage, the crew slept and performed photography and observation of the lunar surface from orbit. Though the crew located 18 landmarks on the surface and took photographs of various surface features, crew fatigue necessitated the cancellation of two scheduled television broadcasts. Thereafter, the main Service Propulsion System engine of the CSM re-ignited for about 2.5 minutes to set Apollo 10 on a trajectory towards Earth, achieving such a trajectory at 137:39:13.7. As it departed lunar orbit, Apollo 10 had orbited the Moon 31 times over the span of about 61 hours and 37 minutes. + +During their journey back to Earth, the crew performed some observational activities which included star-Earth horizon sightings for navigation. The crew also performed a scheduled test to gauge the reflectivity of the CSM's high-gain antenna and broadcast six television transmissions of varying durations to show views inside the spacecraft and of the Earth and Moon from the crew's vantage point. Cernan reported later that he and his crewmates became the first to "successfully shave in space" during the return trip, using a safety razor and thick shaving gel, as such items had been deemed a safety hazard and prohibited on earlier flights. The crew fired the engine of the CSM for the only mid-course-correction burn required during the return trip at 188:49:58, a few hours before separation of the CM from the SM. The burn lasted about 6.7 seconds. + +As the spacecraft rapidly approached Earth on the final day of the mission, the Apollo 10 crew traveled faster than any humans before or since, relative to Earth: 39,897 km/h (11.08 km/s or 24,791 mph). This is because the return trajectory was designed to take only 42 hours rather than the normal 56. The Apollo 10 crew also traveled farther than any humans before or since from their (Houston) homes: (though the Apollo 13 crew was 200 km farther away from Earth as a whole). While most Apollo missions orbited the Moon at from the lunar surface, the distance between the Earth and Moon varies by about , between perigee and apogee, throughout each lunar month, and the Earth's rotation makes the distance to Houston vary by at most another each day. The Apollo 10 crew reached the farthest point in their orbit around the far side of the Moon at about the same time Earth's rotation put Houston nearly a full Earth diameter farther away. + +At 191:33:26, the CM (which contained the crew) separated from the SM in preparation for reentry, which occurred about 15 minutes later at 191:48:54.5. Splashdown of the CM occurred about 15 minutes after reentry in the Pacific Ocean about east of American Samoa on May 26, 1969, at 16:52:23 UTC and mission elapsed time 192:03:23. The astronauts were recovered by . They spent about four hours aboard, during which they took a congratulatory phone call from President Richard Nixon. As they had not made contact with the lunar surface, Apollo 10's crew were not required to quarantine like the first landing crews would be. They were flown to Pago Pago International Airport in Tafuna for a greeting reception, before boarding a C-141 cargo plane to Ellington Air Force Base near Houston. + +Aftermath +Orbital operations and the solo maneuvering of the LM in partial descent to the lunar surface paved the way for the successful Apollo 11 lunar landing by demonstrating the capabilities of the mission hardware and systems. The crew demonstrated that the checkout procedures of the LM and initial descent and rendezvous could be accomplished within the allotted time, that the communication systems of the LM were sufficient, that the rendezvous and landing radars of the LM were operational in lunar orbit, and that the two spacecraft could be adequately monitored by personnel on Earth. Additionally, the precision of lunar orbital navigation improved with Apollo 10 and, combined with data from Apollo 8, NASA expected that it had achieved a level of precision sufficient to execute the first crewed lunar landing. After about two weeks of Apollo 10 data analysis, a NASA flight readiness team cleared Apollo 11 to proceed with its scheduled July 1969 flight. On July 16, 1969, the next Saturn V to launch carried the astronauts of Apollo 11: Neil Armstrong, Buzz Aldrin, and Michael Collins. On July 20, Armstrong and Aldrin landed on the Moon, and four days later the three astronauts returned to Earth, fulfilling John F. Kennedy's challenge to Americans to land astronauts on the Moon and return them safely to Earth by the end of the 1960s. + +In July 1969, Stafford replaced Alan Shepard as Chief Astronaut, and then became deputy director of Flight Crew Operations under Deke Slayton. In his memoirs, Stafford wrote that he could have put his name back in the flight rotation, but wanted managerial experience. In 1972, Stafford was promoted to brigadier general and assigned to command the American portion of the Apollo–Soyuz Test Project, which flew in July 1975. He commanded the Air Force Flight Test Center at Edwards Air Force Base in California, and retired in November 1979 as a lieutenant general. Young commanded the Apollo 16 lunar landing mission flown in April 1972. From 1974 to 1987, Young served as Chief Astronaut, commanding the STS-1 (1981) and STS-9 (1983) Space Shuttle missions in April 1981 and November 1983, respectively, and retired from NASA's Astronaut Corps in 2004. Gene Cernan commanded the final Apollo lunar mission, Apollo 17, flown in December 1972. Cernan retired from NASA and the Navy as a captain in 1976. + +Hardware disposition + +The Smithsonian has been accountable for the command module Charlie Brown since 1970. The spacecraft was on display in several countries until it was placed on loan to the London Science Museum in 1978. Charlie Brown'''s SM was jettisoned just before re-entry and burned up in the Earth's atmosphere, its remnants scattering in the Pacific Ocean. + +After translunar injection, the Saturn V's S-IVB third stage was accelerated past Earth escape velocity to become space debris; , it remains in a heliocentric orbit. + +The ascent stage of the Lunar Module Snoopy was jettisoned into a heliocentric orbit. Snoopys ascent stage orbit was not tracked after 1969, and its whereabouts were unknown. In 2011, a group of amateur astronomers in the UK started a project to search for it. In June 2019, the Royal Astronomical Society announced a possible rediscovery of Snoopy, determining that small Earth-crossing asteroid 2018 AV2 is likely to be the spacecraft with "98%" certainty. It is the only once-crewed spacecraft known to still be in outer space without a crew. + +Snoopy's descent stage was jettisoned in lunar orbit; its current location is unknown, though it may have eventually crashed into the Moon as a result of orbital decay. Phil Stooke, a planetary scientist who studied the lunar crash sites of the LM's ascent stages, wrote that the descent stage "crashed at an unknown location", and another source stated that the descent stage "eventually impact(ed) within a few degrees of the equator on the near side". Richard Orloff and David M. Harland, in their sourcebook on Apollo, stated that "the descent stage was left in the low orbit, but perturbations by 'mascons' would have caused this to decay, sending the stage to crash onto the lunar surface". + +Images + + See also + List of artificial objects on the Moon + List of vehicle speed records + + Notes + + References + + Bibliography + + + + + + + + + + + + + + + + +External links + + "Apollo 10" at Encyclopedia Astronautica + NSSDC Master Catalog at NASA + Apollo 10 Flight JournalNASA reports The Apollo Spacecraft: A Chronology NASA, NASA SP-4009 + "Apollo Program Summary Report" (PDF), NASA, JSC-09423, April 1975 + "Table 2-38.

Stafford +Apollo 12 (November 14–24, 1969) was the sixth crewed flight in the United States Apollo program and the second to land on the Moon. It was launched on November 14, 1969, by NASA from the Kennedy Space Center, Florida. Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. + +Apollo 12 would have attempted the first lunar landing had Apollo 11 failed, but after the success of Neil Armstrong's mission, Apollo 12 was postponed by two months, and other Apollo missions also put on a more relaxed schedule. More time was allotted for geologic training in preparation for Apollo 12 than for Apollo 11, Conrad and Bean making several geology field trips in preparation for their mission. Apollo 12's spacecraft and launch vehicle were almost identical to Apollo 11's. One addition was hammocks to allow Conrad and Bean to rest more comfortably on the Moon. + +Shortly after being launched on a rainy day at Kennedy Space Center, Apollo 12 was twice struck by lightning, causing instrumentation problems but little damage. Switching to the auxiliary power supply resolved the data relay problem, saving the mission. The outward journey to the Moon otherwise saw few problems. On November 19, Conrad and Bean achieved a precise landing at their expected location within walking distance of the Surveyor 3 robotic probe, which had landed on April 20, 1967. In making a pinpoint landing, they showed that NASA could plan future missions in the expectation that astronauts could land close to sites of scientific interest. Conrad and Bean carried the Apollo Lunar Surface Experiments Package, a group of nuclear-powered scientific instruments, as well as the first color television camera taken by an Apollo mission to the lunar surface, but transmission was lost after Bean accidentally pointed the camera at the Sun and its sensor was destroyed. On the second of two moonwalks, they visited Surveyor 3 and removed parts for return to Earth. + +Lunar Module Intrepid lifted off from the Moon on November 20 and docked with the command module, which subsequently traveled back to Earth. The Apollo 12 mission ended on November 24 with a successful splashdown. + +Crew and key Mission Control personnel + +The commander of the all-Navy Apollo 12 crew was Charles "Pete" Conrad, who was 39 years old at the time of the mission. After receiving a bachelor's degree in aeronautical engineering from Princeton University in 1953, he became a naval aviator, and completed United States Naval Test Pilot School at Patuxent River Naval Air Station. He was selected in the second group of astronauts in 1962, and flew on Gemini 5 in 1965, and as command pilot of Gemini 11 in 1966. Command Module Pilot Richard "Dick" Gordon, 40 years old at the time of Apollo 12, also became a naval aviator in 1953, following graduation from the University of Washington with a degree in chemistry, and completed test pilot school at Patuxent River. Selected as a Group 3 astronaut in 1963, he flew with Conrad on Gemini 11. + +The original Lunar Module pilot assigned to work with Conrad was Clifton C. Williams Jr., who was killed in October 1967 when the T-38 he was flying crashed near Tallahassee. When forming his crew, Conrad had wanted Alan L. Bean, a former student of his at the test pilot school, but had been told by Director of Flight Crew Operations Deke Slayton that Bean was unavailable due to an assignment to the Apollo Applications Program. After Williams's death, Conrad asked for Bean again, and this time Slayton yielded. Bean, 37 years old when the mission flew, had graduated from the University of Texas in 1955 with a degree in aeronautical engineering. Also a naval aviator, he was selected alongside Gordon in 1963, and first flew in space on Apollo 12. The three Apollo 12 crew members had backed up Apollo 9 earlier in 1969. + +The Apollo 12 backup crew was David R. Scott as commander, Alfred M. Worden as Command Module pilot, and James B. Irwin as Lunar Module pilot. They became the crew of Apollo 15. For Apollo, a third crew of astronauts, known as the support crew, was designated in addition to the prime and backup crews used on projects Mercury and Gemini. Slayton created the support crews because James McDivitt, who would command Apollo 9, believed that, with preparation going on in facilities across the US, meetings that needed a member of the flight crew would be missed. Support crew members were to assist as directed by the mission commander. Usually low in seniority, they assembled the mission's rules, flight plan, and checklists, and kept them updated; For Apollo 12, they were Gerald P. Carr, Edward G. Gibson and Paul J. Weitz. Flight directors were Gerry Griffin, first shift, Pete Frank, second shift, Clifford E. Charlesworth, third shift, and Milton Windler, fourth shift. Flight directors during Apollo had a one-sentence job description, "The flight director may take any actions necessary for crew safety and mission success." Capsule communicators (CAPCOMs) were Scott, Worden, Irwin, Carr, Gibson, Weitz and Don Lind. + +Preparation + +Site selection +The landing site selection process for Apollo 12 was greatly informed by the site selection for Apollo 11. There were rigid standards for the possible Apollo 11 landing sites, in which scientific interest was not a major factor: they had to be close to the lunar equator and not on the periphery of the portion of the lunar surface visible from Earth; they had to be relatively flat and without major obstructions along the path the Lunar Module (LM) would fly to reach them, their suitability confirmed by photographs from Lunar Orbiter probes. Also desirable was the presence of another suitable site further west in case the mission was delayed, and the sun would have risen too high in the sky at the original site for desired lighting conditions. The need for three days to recycle if a launch had to be scrubbed meant that only three of the five suitable sites found were designated as potential landing sites for Apollo 11, of which the Apollo 11 landing site in the Sea of Tranquility was the easternmost. Since Apollo 12 was to attempt the first lunar landing if Apollo 11 failed, both sets of astronauts trained for the same sites. + +With the success of Apollo 11, it was initially contemplated that Apollo 12 would land at the site next further west from the Sea of Tranquility, in Sinus Medii. However, NASA planning coordinator Jack Sevier and engineers at the Manned Spaceflight Center at Houston argued for a landing close enough to the crater in which the Surveyor 3 probe had landed in 1967 to allow the astronauts to cut parts from it for return to Earth. The site was otherwise suitable and had scientific interest. Given that Apollo 11 had landed several miles off-target, though, some NASA administrators feared Apollo 12 would land far enough away that the astronauts could not reach the probe, and the agency would be embarrassed. Nevertheless, the ability to perform pinpoint landings was essential if Apollo's exploration program was to be carried out, and on July 25, 1969, Apollo Program Manager Samuel Phillips designated what became known as Surveyor crater as the landing site, despite the unanimous opposition of members of two site selection boards. + +Training and preparation + +The Apollo 12 astronauts spent five hours in mission-specific training for every hour they expected to spend in flight on the mission, a total exceeding 1,000 hours per crew member. Conrad and Bean received more mission-specific training than Apollo 11's Neil Armstrong and Buzz Aldrin had. This was in addition to the 1,500 hours of training they received as backup crew members for Apollo 9. The Apollo 12 training included over 400 hours per crew member in simulators of the Command Module (CM) and of the LM. Some of the simulations were linked in real time to flight controllers in Mission Control. To practice landing on the Moon, Conrad flew the Lunar Landing Training Vehicle (LLTV), training in which continued to be authorized even though Armstrong had been forced to bail out of a similar vehicle in 1968, just before it crashed. + +Soon after being assigned as Apollo 12 crew commander, Conrad met with NASA geologists and told them that the training for lunar surface activities would be conducted much as Apollo 11's, but there was to be no publicity or involvement by the media. Conrad felt he had been abused by the press during Gemini, and the sole Apollo 11 geology field trip had turned into a near-fiasco, with a large media contingent present, some getting in the way—the astronauts had trouble hearing each other due to a hovering press helicopter. After the successful return of Apollo 11 in July 1969, more time was allotted for geology, but the astronauts' focus was in getting time in the simulators without being pre-empted by the Apollo 11 crew. On the six Apollo 12 geology field trips, the astronauts would practice as if on the Moon, collecting samples and documenting them with photographs, while communicating with a CAPCOM and geologists who were out of sight in a nearby tent. Afterwards, the astronauts' performance in choosing samples and taking photographs would be critiqued. To the frustration of the astronauts, the scientists kept changing the photo documentation procedures; after the fourth or fifth such change, Conrad required that there be no more. After the return of Apollo 11, the Apollo 12 crew was able to view the lunar samples, and be briefed on them by scientists. + +As Apollo 11 was targeted for an ellipse-shaped landing zone, rather than at a specific point, there was no planning for geology traverses, the designated tasks to be done at sites of the crew's choosing. For Apollo 12, before the mission, some of NASA's geology team met with the crew and Conrad suggested they lay out possible routes for him and Bean. The result was four traverses, based on four potential landing points for the LM. This was the start of geology traverse planning that on later missions became a considerable effort involving several organizations. + +The stages of the lunar module, LM–6, were delivered to Kennedy Space Center (KSC) on March 24, 1969, and were mated to each other on April 28. Command module CM–108 and service module SM–108 were delivered to KSC on March 28, and were mated to each other on April 21. Following installation of gear and testing, the launch vehicle, with the spacecraft atop it, was rolled out to Launch Complex 39A on September 8, 1969. The training schedule was complete, as planned, by November 1, 1969; activities after that date were intended as refreshers. The crew members felt that the training, for the most part, was adequate preparation for the Moon mission. + +Hardware + +Launch vehicle + +There were no significant changes to the Saturn V launch vehicle used on Apollo 12, SA–507, from that used on Apollo 11. There were another 17 instrumentation measurements in the Apollo 12 launch vehicle, bringing the number to 1,365. The entire vehicle, including the spacecraft, weighed at launch, an increase from Apollo 11's . Of this figure, the spacecraft weighed , up from on Apollo 11. + +Third stage trajectory +After LM separation, the third stage of the Saturn V, the S-IVB, was intended to fly into solar orbit. The S-IVB auxiliary propulsion system was fired, with the intent that the Moon's gravity slingshot the stage into solar orbit. Due to an error, the S-IVB flew past the Moon at too high an altitude to achieve Earth escape velocity. It remained in a semi-stable Earth orbit until it finally escaped Earth orbit in 1971, but briefly returned to Earth orbit 31 years later. It was discovered by amateur astronomer Bill Yeung who gave it the temporary designation J002E3 before it was determined to be an artificial object. Again in solar orbit as of 2021, it may again be captured by Earth's gravity, but not at least until the 2040s. The S-IVBs used on later lunar missions were deliberately crashed into the Moon to create seismic events that would register on the seismometers left on the Moon and provide data about the Moon's structure. + +Spacecraft + +The Apollo 12 spacecraft consisted of Command Module 108 and Service Module 108 (together Command and Service Modules 108, or CSM–108), Lunar Module 6 (LM–6), a Launch Escape System (LES), and Spacecraft-Lunar Module Adapter 15 (SLA–15). The LES contained three rocket motors to propel the CM to safety in the event of an abort shortly after launch, while the SLA housed the LM and provided a structural connection between the Saturn V and the LM. The SLA was identical to Apollo 11's, while the LES differed only in the installation of a more reliable motor igniter. + +The CSM was given the call sign Yankee Clipper, while the LM had the call sign Intrepid. These sea-related names were selected by the all-Navy crew from several thousand proposed names submitted by employees of the prime contractors of the respective modules. George Glacken, a flight test engineer at North American Aviation, builder of the CSM, proposed Yankee Clipper as such ships had "majestically sailed the high seas with pride and prestige for a new America". Intrepid was from a suggestion by Robert Lambert, a planner at Grumman, builder of the LM, as evocative of "this nation's resolute determination for continued exploration of space, stressing our astronauts' fortitude and endurance of hardship". + +The differences between the CSM and LM of Apollo 11, and those of Apollo 12, were few and minor. A hydrogen separator was added to the CSM to stop the gas from entering the potable water tank—Apollo 11 had had one, though mounted on the water dispenser in the CM's cabin. Gaseous hydrogen in the water had given the Apollo 11 crew severe flatulence. Other changes included the strengthening of the recovery loop attached following splashdown, meaning that the swimmers recovering the CM would not have to attach an auxiliary loop. LM changes included a structural modification so that scientific experiment packages could be carried for deployment on the lunar surface. Two hammocks were added for greater comfort of the astronauts while resting on the Moon, and a color television camera substituted for the black and white one used on the lunar surface during Apollo 11. + +ALSEP + +The Apollo Lunar Surface Experiments Package, or ALSEP, was a suite of scientific instruments designed to be emplaced on the lunar surface by the Apollo astronauts, and thereafter operate autonomously, sending data to Earth. Development of the ALSEP was part of NASA's response to some scientists who opposed the crewed lunar landing program (they felt that robotic craft could explore the Moon more cheaply) by demonstrating that some tasks, such as deployment of the ALSEP, required humans. In 1966, a contract to design and build the ALSEPs was awarded to the Bendix Corporation Due to the limited time the Apollo 11 crew would have on the lunar surface, a smaller suite of experiments was flown, known as the Early Apollo Surface Experiment Package (EASEP). Apollo 12 was the first mission to carry an ALSEP; one would be flown on each of the subsequent lunar landing missions, though the components that were included would vary. Apollo 12's ALSEP was to be deployed at least away from the LM to protect the instruments from the debris that would be generated when the ascent stage of the LM took off to return the astronauts to lunar orbit. + +Apollo 12's ALSEP included a Lunar Surface Magnetometer (LSM), to measure the magnetic field at the Moon's surface, a Lunar Atmosphere Detector (LAD, also known as the Cold Cathode Ion Gauge Experiment), intended to measure the density and temperature of the thin lunar atmosphere and how it varies, a Lunar Ionosphere Detector (LID, also known as the Charged Particle Lunar Environment Experiment, or CPLEE), intended to study the charged particles in the lunar atmosphere, and the Solar Wind Spectrometer, to measure the strength and direction of the solar wind at the Moon's surface—the free-standing Solar Wind Composition Experiment, to measure what makes up the solar wind, would be deployed and then brought back to Earth by the astronauts. A Dust Detector was used to measure the accumulation of lunar dust on the equipment. Apollo 12's Passive Seismic Experiment (PSE), a seismometer, would measure moonquakes and other movements in the Moon's crust, and would be calibrated by the nearby planned impact of the ascent stage of Apollo 12's LM, an object of known mass and velocity hitting the Moon at a known location, and projected to be equivalent to the explosive force of one ton of TNT. + +The ALSEP experiments left on the Moon by Apollo 12 were connected to a Central Station, which contained a transmitter, receiver, timer, data processor, and equipment for power distribution and control of the experiments. The equipment was powered by SNAP-27, a radioisotope thermoelectric generator (RTG) developed by the Atomic Energy Commission. Containing plutonium, the RTG flown on Apollo 12 was the first use of atomic energy on a crewed NASA spacecraft—some NASA and military satellites had previously used similar systems. The plutonium core was brought from Earth in a cask attached to an LM landing leg, a container designed to survive re-entry in the event of an aborted mission, something NASA considered unlikely. The cask would survive re-entry on Apollo 13, sinking in the Tonga Trench of the Pacific Ocean, apparently without radioactive leakage. + +The Apollo 12 ALSEP experiments were activated from Earth on November 19, 1969. The LAD returned only a small amount of useful data due to the failure of its power supply soon after activation. The LSM was deactivated on June 14, 1974, as was the other LSM deployed on the Moon, from Apollo 15. All powered ALSEP experiments that remained active were deactivated on September 30, 1977, principally because of budgetary constraints. + +Mission highlights + +Launch +With President Richard Nixon in attendance, the first time a current U.S. president had witnessed a crewed space launch, as well as Vice President Spiro Agnew, Apollo 12 launched as planned at 11:22:00 on November 14, 1969 (16:22:00 UT) from Kennedy Space Center. This was at the start of a launch window of three hours and four minutes to reach the Moon with optimal lighting conditions at the planned landing point. There were completely overcast rainy skies, and the vehicle encountered winds of during ascent, the strongest of any Apollo mission. There was a NASA rule against launching into a cumulonimbus cloud; this had been waived and it was later determined that the launch vehicle never entered such a cloud. Had the mission been postponed, it could have been launched on November 16 with landing at a backup site where there would be no Surveyor, but since time pressure to achieve a lunar landing had been removed by Apollo 11's success, NASA might have waited until December for the next opportunity to go to the Surveyor crater. + +Lightning struck the Saturn V 36.5 seconds after lift-off, triggered by the vehicle itself. The static discharge caused a voltage transient that knocked all three fuel cells offline, meaning the spacecraft was being powered entirely from its batteries, which could not supply enough current to meet demand. A second strike at 52 seconds knocked out the "8-ball" attitude indicator. The telemetry stream at Mission Control was garbled, but the Saturn V continued to fly normally; the strikes had not affected the Saturn V instrument unit guidance system, which functioned independently from the CSM. The astronauts unexpectedly had a board red with caution and warning lights, but could not tell exactly what was wrong. + +The Electrical, Environmental and Consumables Manager (EECOM) in Mission Control, John Aaron, remembered the telemetry failure pattern from an earlier test when a power loss caused a malfunction in the CSM signal conditioning electronics (SCE), which converted raw signals from instrumentation to data that could be displayed on Mission Control's consoles, and knew how to fix it. Aaron made a call, "Flight, EECOM. Try SCE to Aux", to switch the SCE to a backup power supply. The switch was fairly obscure, and neither Flight Director Gerald Griffin, CAPCOM Gerald P. Carr, nor Conrad knew what it was; Bean, who as LMP was the spacecraft's engineer, knew where to find it and threw the switch, after which the telemetry came back online, revealing no significant malfunctions. Bean put the fuel cells back online, and the mission continued. Once in Earth parking orbit, the crew carefully checked out their spacecraft before re-igniting the S-IVB third stage for trans-lunar injection. The lightning strikes caused no serious permanent damage. + +Initially, it was feared that the lightning strike could have damaged the explosive bolts that opened the Command Module's parachute compartment. The decision was made not to share this with the astronauts and to continue with the flight plan, since they would die if the parachutes failed to deploy, whether following an Earth-orbit abort or upon a return from the Moon, so nothing was to be gained by aborting. The parachutes deployed and functioned normally at the end of the mission. + +Outward journey + +After systems checks in Earth orbit, performed with great care because of the lightning strikes, the trans-lunar injection burn, made with the S-IVB, took place at 02:47:22.80 into the mission, setting Apollo 12 on course for the Moon. An hour and twenty minutes later, the CSM separated from the S-IVB, after which Gordon performed the transposition, docking and extracting maneuver to dock with the LM and separate the combined craft from the S-IVB, which was then sent on an attempt to reach solar orbit. The stage fired its engines to leave the vicinity of the spacecraft, a change from Apollo 11, where the SM's Service Propulsion System (SPS) engine was used to distance it from the S-IVB. + +As there were concerns the LM might have been damaged by the lightning strikes, Conrad and Bean entered it on the first day of flight to check its status, earlier than planned. They found no issues. At 30:52.44.36, the only necessary midcourse correction during the translunar coast was made, placing the craft on a hybrid, non-free-return trajectory. Previous crewed missions to lunar orbit had taken a free-return trajectory, allowing an easy return to Earth if the craft's engines did not fire to enter lunar orbit. Apollo 12 was the first crewed spacecraft to take a hybrid free-return trajectory, that would require another burn to return to Earth, but one that could be executed by the LM's Descent Propulsion System (DPS) if the SPS failed. The use of a hybrid trajectory allowed more flexibility in mission planning. It for example allowed Apollo 12 to launch in daylight and reach the planned landing spot on schedule. Use of a hybrid trajectory meant that Apollo 12 took 8 hours longer to go from trans-lunar injection to lunar orbit. + +Lunar orbit and Moon landing + +Apollo 12 entered a lunar orbit of with an SPS burn of 352.25 seconds at mission time 83:25:26.36. On the first lunar orbit, there was a television transmission that resulted in good-quality video of the lunar surface. On the third lunar orbit, there was another burn to circularize the craft's orbit to , and on the next revolution, preparations began for the lunar landing. The CSM and LM undocked at 107:54:02.3; a half hour later there was a burn by the CSM to separate them. The 14.4 second burn by some of the CSM's thrusters meant that the two craft would be apart when the LM began the burn to move to a lower orbit in preparation for landing on the Moon. + +The LM's Descent Propulsion System began a 29-second burn at 109:23:39.9 to move the craft to the lower orbit, from which the 717-second powered descent to the lunar surface began at 110:20:38.1. Conrad had trained to expect a pattern of craters known as "the Snowman" to be visible when the craft underwent "pitchover", with the Surveyor crater in its center, but had feared he would see nothing recognizable. He was astonished to see the Snowman right where it should be, meaning they were directly on course. He took over manual control, planning to land the LM, as he had in simulations, in an area near the Surveyor crater that had been dubbed "Pete's Parking Lot", but found it rougher than expected. He had to maneuver, and landed the LM +at 110:32:36.2 (06:54:36 UT on November 19, 1969), just from the Surveyor probe. This achieved one objective of the mission, to perform a precision landing near the Surveyor craft. + +The lunar coordinates of the landing site were 3.01239° S latitude, 23.42157° W longitude. The landing caused high velocity sandblasting of the Surveyor probe. It was later determined that the sandblasting removed more dust than it delivered onto the Surveyor, because the probe was covered by a thin layer that gave it a tan hue as observed by the astronauts, and every portion of the surface exposed to the direct sandblasting was lightened back toward the original white color through the removal of lunar dust. + +Lunar surface activities +When Conrad, the shortest man of the initial groups of astronauts, stepped onto the lunar surface his first words were "Whoopie! Man, that may have been a small one for Neil, but that's a long one for me." This was not an off-the-cuff remark: Conrad had made a bet with reporter Oriana Fallaci he would say these words, after she had queried whether NASA had instructed Neil Armstrong what to say as he stepped onto the Moon. Conrad later said he was never able to collect the money. + +To improve the quality of television pictures from the Moon, a color camera was carried on Apollo 12 (unlike the monochrome camera on Apollo 11). When Bean carried the camera to the place near the LM where it was to be set up, he inadvertently pointed it directly into the Sun, destroying the Secondary Electron Conduction (SEC) tube. Television coverage of this mission was thus terminated almost immediately. + +After raising a U.S. flag on the Moon, Conrad and Bean devoted much of the remainder of the first EVA to deploying the Apollo Lunar Surface Experiments Package (ALSEP). There were minor difficulties with the deployment. Bean had trouble extracting the RTG's plutonium fuel element from its protective cask, and the astronauts had to resort to the use of a hammer to hit the cask and dislodge the fuel element. Some of the ALSEP packages proved hard to deploy, though the astronauts were successful in all cases. With the PSE able to detect their footprints as they headed back to the LM, the astronauts secured a core tube full of lunar material, and collected other samples. The first EVA lasted 3 hours, 56 minutes and 3 seconds. + +Four possible geologic traverses had been planned, the variable being where the LM might set down. Conrad had landed it between two of these potential landing points, and during the first EVA and the rest break that followed, scientists in Houston combined two of the traverses into one that Conrad and Bean could follow from their landing point. The resultant traverse resembled a rough circle, and when the astronauts emerged from the LM some 13 hours after ending the first EVA, the first stop was Head crater, some from the LM. There, Bean noticed that Conrad's footprints showed lighter material underneath, indicating the presence of ejecta from Copernicus crater, to the north, something that scientists examining overhead photographs of the site had hoped to find. After the mission, samples from Head allowed geologists to date the impact that formed Copernicus—according to initial dating, some 810,000,000 years ago. + +The astronauts proceeded to Bench crater and Sharp crater and past Halo crater before arriving at Surveyor crater, where the Surveyor 3 probe had landed. Fearing treacherous footing or that the probe might topple on them, they approached Surveyor cautiously, descending into the shallow crater some distance away and then following a contour to reach the craft, but found the footing solid and the probe stable. They collected several pieces of Surveyor, including the television camera, as well as taking rocks that had been studied by television. Conrad and Bean had procured an automatic timer for their Hasselblad cameras, and had brought it with them without telling Mission Control, hoping to take a selfie of the two of them with the probe, but when the time came to use it, could not locate it among the lunar samples they had already placed in their Hand Tool Carrier. Before returning to the LM's vicinity, Conrad and Bean went to Block crater, within Surveyor crater. The second EVA lasted 3 hours, 49 minutes, 15 seconds, during which they traveled . During the EVAs, Conrad and Bean went as far as from the LM, and collected of samples. + +Lunar orbit solo activities + +After the LM's departure, Gordon had little to say as Mission Control focused on the lunar landing. Once that was accomplished, Gordon sent his congratulations and, on the next orbit, was able to spot both the LM and the Surveyor on the ground and convey their locations to Houston. During the first EVA, Gordon prepared for a plane change maneuver, a burn to alter the CSM's orbit to compensate for the rotation of the Moon, though at times he had difficulty communicating with Houston since Conrad and Bean were using the same communications circuit. Once the two moonwalkers had returned to the LM, Gordon executed the burn, which ensured he would be in the proper position to rendezvous with the LM when it launched from the Moon. + +While alone in orbit, Gordon performed the Lunar Multispectral Photography Experiment, using four Hasselblad cameras arranged in a ring and aimed through one of the CM's windows. With each camera having a different color filter, simultaneous photos would be taken by each, showing the appearance of lunar features at different points on the spectrum. Analysis of the images might reveal colors not visible to the naked eye or detectable with ordinary color film, and information could be obtained about the composition of sites that would not soon be visited by humans. Among the sites studied were contemplated landing points for future Apollo missions. + +Return + +LM Intrepid lifted off from the Moon at mission time 143:03:47.78, or 14:25:47 UT on November 20, 1969; after several maneuvers, CSM and LM docked three and a half hours later. At 147:59:31.6, the LM ascent stage was jettisoned, and shortly thereafter the CSM maneuvered away. Under control from Earth, the LM's remaining propellent was depleted in a burn that caused it to impact the Moon from the Apollo 12 landing point. The seismometer the astronauts had left on the lunar surface registered the resulting vibrations for more than an hour. + +The crew stayed another day in lunar orbit taking photographs of the surface, including of candidate sites for future Apollo landings. A second plane change maneuver was made at 159:04:45.47, lasting 19.25 seconds. + +The trans-Earth injection burn, to send the CSM Yankee Clipper towards home, was conducted at 172:27:16.81 and lasted 130.32 seconds. Two short midcourse correction burns were made en route. A final television broadcast was made, the astronauts answering questions submitted by the media. There was ample time for rest on the way back to Earth, One event was the photography of a solar eclipse that occurred when the Earth came between the spacecraft and the Sun; Bean described it as the most spectacular sight of the mission. + +Splashdown +Yankee Clipper returned to Earth on November 24, 1969, at 20:58 UT (3:58pm Eastern Time, 10:58am HST), in the Pacific Ocean. The landing was hard, resulting in a camera becoming dislodged and striking Bean in the forehead. After recovery by , they entered the Mobile Quarantine Facility (MQF), while lunar samples and Surveyor parts were sent ahead by air to the Lunar Receiving Laboratory (LRL) in Houston. Once the Hornet docked in Hawaii, the MQF was offloaded and flown to Ellington Air Force Base near Houston on November 29, from where it was taken to the LRL, where the astronauts remained until released from quarantine on December 10. + +Mission insignia + +The Apollo 12 mission patch shows the crew's naval background; all three astronauts at the time of the mission were U.S. Navy commanders. It features a clipper ship arriving at the Moon, representing the CM Yankee Clipper. The ship trails fire, and flies the flag of the United States. The mission name APOLLO XII and the crew names are on a wide gold border, with a small blue trim. Blue and gold are traditional U.S. Navy colors. The patch has four stars on it – one each for the three astronauts who flew the mission and one for Clifton Williams, the original LMP on Conrad's crew who was killed in 1967 and would have flown the mission. The star was placed there at the suggestion of his replacement, Bean. + +The insignia was designed by the crew with the aid of several employees of NASA contractors. The Apollo 12 landing area on the Moon is within the portion of the lunar surface shown on the insignia, based on a photograph of a globe of the Moon, taken by engineers. The clipper ship was based on photographs of such a ship obtained by Bean. + +Aftermath and spacecraft location + +After the mission, Conrad urged his crewmates to join him in the Skylab program, seeing in it the best chance of flying in space again. Bean did so—Conrad commanded Skylab 2, the first crewed mission to the space station, while Bean commanded Skylab 3. Gordon, though, still hoped to walk on the Moon and remained with the Apollo program, serving as backup commander of Apollo 15. He was the likely commander of Apollo 18, but that mission was canceled and he did not fly in space again. + +The Apollo 12 command module Yankee Clipper, was displayed at the Paris Air Show and was then placed at NASA's Langley Research Center in Hampton, Virginia; ownership was transferred to the Smithsonian in July 1971. It is on display at the Virginia Air and Space Center in Hampton. + +Mission Control had remotely fired the service module's thrusters after jettison, hoping to have it skip off the atmosphere and enter a high-apogee orbit, but the lack of tracking data confirming this caused it to conclude it most likely burned up in the atmosphere at the time of CM re-entry. The S-IVB is in a solar orbit that is sometimes affected by the Earth. + +The ascent stage of LM Intrepid impacted the Moon November 20, 1969, at 22:17:17.7 UT (5:17pm EST). In 2009, the Lunar Reconnaissance Orbiter (LRO) photographed the Apollo 12 landing site, where the descent stage, ALSEP, Surveyor3 spacecraft, and astronaut footpaths remain. In 2011, the LRO returned to the landing site at a lower altitude to take higher resolution photographs. + +See also + List of artificial objects on the Moon + List of spacewalks and moonwalks 1965–1999 + +References + +Bibliography + +External links + + "Apollo 12" at Encyclopedia Astronautica + "Apollo 12" at NASA's National Space Science Data Center + Apollo 11, 12, and 14 Traverses, at the Lunar and Planetary Institute + "Apollo 12 Traverse Map" at the USGS Astrogeology Science Center + Lunar Orbiter 3 image 154 H2, used for planning the mission (landing site is left of center). + Lunar Orbiter 1 sequence of images 157, 158, and 159, showing the Apollo 12 landing site and vicinity + +NASA reports + "Apollo 12 Preliminary Science Report" (PDF), NASA, NASA SP-235, 1970 + "Analysis of Apollo 12 Lightning Incident", (PDF) February 1970 + "Analysis of Surveyor 3 material and photographs returned by Apollo 12" (PDF) 1972 + "Examination of Surveyor 3 surface sampler scoop"(PDF) 1971 + "Table 2-40.

It was the last of the "H missions", landings at specific sites of scientific interest on the Moon for two-day stays with two lunar extravehicular activities (EVAs or moonwalks). + +The mission was originally scheduled for 1970, but was postponed because of the investigation following the failure of Apollo 13 to reach the Moon's surface, and the need for modifications to the spacecraft as a result. Commander Alan Shepard, Command Module Pilot Stuart Roosa, and Lunar Module Pilot Edgar Mitchell launched on their nine-day mission on Sunday, January 31, 1971, at 4:03:02 p.m. EST. En route to the lunar landing, the crew overcame malfunctions that might have resulted in a second consecutive aborted mission, and possibly, the premature end of the Apollo program. + +Shepard and Mitchell made their lunar landing on February 5 in the Fra Mauro formation – originally the target of Apollo 13. During the two walks on the surface, they collected of Moon rocks and deployed several scientific experiments. To the dismay of some geologists, Shepard and Mitchell did not reach the rim of Cone crater as had been planned, though they came close. In Apollo 14's most famous event, Shepard hit two golf balls he had brought with him with a makeshift club. + +While Shepard and Mitchell were on the surface, Roosa remained in lunar orbit aboard the Command and Service Module, performing scientific experiments and photographing the Moon, including the landing site of the future Apollo 16 mission. He took several hundred seeds on the mission, many of which were germinated on return, resulting in the so-called Moon trees, that were widely distributed in the following years. After liftoff from the lunar surface and a successful docking, the spacecraft was flown back to Earth where the three astronauts splashed down safely in the Pacific Ocean on February 9. + +Astronauts and key Mission Control personnel + +The mission commander of Apollo 14, Alan Shepard, one of the original Mercury Seven astronauts, became the first American to enter space with a suborbital flight on May 5, 1961. Thereafter, he was grounded by Ménière's disease, a disorder of the ear, and served as Chief Astronaut, the administrative head of the Astronaut Office. He had experimental surgery in 1968 which was successful and allowed his return to flight status. Shepard, at age 47, was the oldest U.S. astronaut to fly when he made his trip aboard Apollo 14, and he is the oldest person to walk on the Moon. + +Apollo 14's Command Module Pilot (CMP), Stuart Roosa, aged 37 when the mission flew, had been a smoke jumper before joining the Air Force in 1953. He became a fighter pilot and then in 1965 successfully completed Aerospace Research Pilot School (ARPS) at Edwards Air Force Base in California prior to his selection as a Group 5 astronaut the following year. He served as a capsule communicator (CAPCOM) for Apollo 9. The Lunar Module Pilot (LMP), Edgar Mitchell, aged 40 at the time of Apollo 14, joined the Navy in 1952 and served as a fighter pilot, beginning in 1954. He was assigned to squadrons aboard aircraft carriers before returning to the United States to further his education while in the Navy, also completing the ARPS prior to his selection as a Group 5 astronaut. He served on the support crew for Apollo 9 and was the LMP of the backup crew for Apollo 10. + +Shepard and his crew had originally been designated by Deke Slayton, Director of Flight Crew Operations and one of the Mercury Seven, as the crew for Apollo 13. NASA's management felt that Shepard needed more time for training given he had not flown in space since 1961, and chose him and his crew for Apollo 14 instead. The crew originally designated for Apollo 14, Jim Lovell as the commander, Ken Mattingly as CMP and Fred Haise as LMP, all of whom had backed up Apollo 11, was made the prime crew for Apollo 13 instead. + +Mitchell's commander on the Apollo 10 backup crew had been another of the original seven, Gordon Cooper, who had tentatively been scheduled to command Apollo 13, but according to author Andrew Chaikin, his casual attitude toward training resulted in him being not selected. Also on that crew, but excluded from further flights, was Donn Eisele, likely because of problems aboard Apollo 7, which he had flown, and because he had been involved in a messy divorce. + +Apollo 14's backup crew was Eugene A. Cernan as commander, Ronald E. Evans Jr. as CMP and Joe H. Engle as LMP. The backup crew, with Harrison Schmitt replacing Engle, would become the prime crew of Apollo 17. Schmitt flew instead of Engle because there was intense pressure on NASA to fly a scientist to the Moon (Schmitt was a geologist) and Apollo 17 was the last lunar flight. Engle, who had flown the X-15 to the edge of outer space, flew into space for NASA in 1981 on STS-2, the second Space Shuttle flight. + +During projects Mercury and Gemini, each mission had a prime and a backup crew. Apollo 9 commander James McDivitt believed meetings that required a member of the flight crew were being missed, so for Apollo a third crew of astronauts was added, known as the support crew. Usually low in seniority, support crew members assembled the mission's rules, flight plan, and checklists, and kept them updated; for Apollo 14, they were Philip K. Chapman, Bruce McCandless II, William R. Pogue and C. Gordon Fullerton. CAPCOMs, the individuals in Mission Control responsible for communications with the astronauts were Evans, McCandless, Fullerton and Haise. A veteran of Apollo 13, which had aborted before reaching the Moon, Haise put his training for that mission to use, especially during the EVAs, since both missions were targeted at the same place on the Moon. Had Haise walked on the Moon, he would have been the first Group 5 astronaut to do so, an honor that went to Mitchell. + +The flight directors during Apollo had a one-sentence job description, "The flight director may take any actions necessary for crew safety and mission success." For Apollo 14, they were: Pete Frank, Orange team; Glynn Lunney, Black team; Milt Windler, Maroon team and Gerry Griffin, Gold team. + +Preparation and training + +Prime and backup crews for both Apollo 13 and 14 were announced on August 6, 1969. Apollo 14 was scheduled for July 1970, but in January of that year, due to budget cuts that saw the cancellation of Apollo 20, NASA decided there would be two Apollo missions per year with 1970 to see Apollo 13 in April and Apollo 14 likely in October or November. + +The investigation into the accident which caused an abort of Apollo 13 delayed Apollo 14. On May 7, 1970, NASA Administrator Thomas O. Paine announced that Apollo 14 would launch no earlier than December 3, and the landing would be close to the site targeted by Apollo 13. The Apollo 14 astronauts continued their training. On June 30, 1970, following the release of the accident report and a NASA review of what changes to the spacecraft would be necessary, NASA announced that the launch would slip to no earlier than January 31, 1971. + +The crew of Apollo 14 trained together for 19 months after assignment to the mission, longer than any other Apollo crew to that point. In addition to the normal training workload, they had to supervise the changes to the command and service module (CSM) made as a result of the Apollo 13 investigation, much of which was delegated by Shepard to Roosa. Mitchell later stated, "We realized that if our mission failed—if we had to turn back—that was probably the end of the Apollo program. There was no way NASA could stand two failures in a row. We figured there was a heavy mantle on our shoulders to make sure we got it right." + +Before the abort of the Apollo 13 mission, the plan was to have Apollo 14 land near Littrow crater, in Mare Serenitatis, where there are features that were thought to be volcanic. After Apollo 13 returned, it was decided that its landing site, near Cone crater in the Fra Mauro formation, was scientifically more important than Littrow. The Fra Mauro formation is composed of ejecta from the impact event that formed Mare Imbrium, and scientists hoped for samples that originated deep under the Moon's surface. Cone crater was the result of a young, deep impact, and large enough to have torn through whatever debris was deposited since the Imbrium Event, which geologists hoped to be able to date. Landing at Fra Mauro would also allow orbital photography of another candidate landing site, the Descartes Highlands, which became the landing site for Apollo 16. Although Littrow went unvisited, a nearby area, Taurus-Littrow, was the landing site for Apollo 17. Apollo 14's landing site was located slightly closer to Cone crater than the point designated for Apollo 13. + +The change in landing site from Littrow to Fra Mauro affected the geological training for Apollo 14. Before the switch, the astronauts had been taken to volcanic sites on Earth; afterwards, they visited crater sites, such as the Ries Crater in West Germany and an artificial crater field created for astronaut training in Arizona's Verde Valley. The effectiveness of the training was limited by a lack of enthusiasm shown by Shepard, which set the tone for Mitchell. Harrison Schmitt suggested that the commander had other things on his mind, such as overcoming a ten-year absence from spaceflight and ensuring a successful mission after the near-disaster of Apollo 13. + +Roosa undertook training for his period alone in lunar orbit, when he would make observations of the Moon and take photographs. He had been impressed by the training given to Apollo 13 prime crew CMP Mattingly by geologist Farouk El-Baz and got El-Baz to agree to undertake his training. The two men pored over lunar maps depicting the areas the CSM would pass over. When Shepard and Mitchell were on their geology field trips, Roosa would be overhead in an airplane taking photographs of the site and making observations. El-Baz had Roosa make observations while flying his T-38 jet at a speed and altitude simulating the speed at which the lunar surface would pass below the CSM. + +Another issue that had marked Apollo 13 was the last-minute change of crew due to exposure to communicable disease. To prevent another such occurrence, for Apollo 14 NASA instituted what was called the Flight Crew Health Stabilization Program. Beginning 21 days before launch, the crew lived in quarters at the launch site, Florida's Kennedy Space Center (KSC), with their contacts limited to their spouses, the backup crew, mission technicians, and others directly involved in training. Those individuals were given physical examinations and immunizations, and crew movements were limited as much as possible at KSC and nearby areas. + +The Command and Service Modules were delivered to KSC on November 19, 1969; the ascent stage of the LM arrived on November 21 with the descent stage three days later. Thereafter, checkout, testing and equipment installation proceeded. The launch vehicle stack, with the spacecraft on top, was rolled out from the Vehicle Assembly Building to Pad 39A on November 9, 1970. + +Hardware + +Spacecraft + +The Apollo 14 spacecraft consisted of Command Module (CM) 110 and Service Module (SM) 110 (together CSM-110), called Kitty Hawk, and Lunar Module 8 (LM-8), called Antares. Roosa had chosen the CSM's call sign after the town in North Carolina where, in 1903, the Wright Brothers first flew their Wright Flyer airplane (also known as Kitty Hawk). Antares was named by Mitchell after the star in the constellation Scorpius that the astronauts in the LM would use to orient the craft for its lunar landing. Also considered part of the spacecraft were a Launch Escape System and a Spacecraft/Launch Vehicle Adapter, numbered SLA-17. + +The changes to the Apollo spacecraft between Apollo 13 and 14 were more numerous than with earlier missions, not only because of the problems with Apollo 13, but because of the more extensive lunar activities planned for Apollo 14. The Apollo 13 accident had been caused by the explosive failure of an oxygen tank, after the insulation of the internal wiring had been damaged by heating of the tank contents pre-launch—that the oxygen had gotten hot enough to damage the insulation had not been realized, since the protective thermostatic switches had failed because they were, through an error, not designed to handle the voltage applied during ground testing. The explosion damaged the other tank or its tubing, causing its contents to leak away. + +The changes in response included a redesign of the oxygen tanks, with the thermostats being upgraded to handle the proper voltage. A third tank was also added, placed in Bay1 of the SM, on the side opposite the other two, and was given a valve that could isolate it in an emergency, and allow it to feed the CM's environmental system only. The quantity probe in each tank was upgraded from aluminum to stainless steel. + +Also in response to the Apollo 13 accident, the electrical wiring in Bay4 (where the explosion had happened) was sheathed in stainless steel. The fuel cell oxygen supply valves were redesigned to isolate the Teflon-coated wiring from the oxygen. The spacecraft and Mission Control monitoring systems were modified to give more immediate and visible warnings of anomalies. The Apollo 13 astronauts had suffered shortages of water and of power after the accident. Accordingly, an emergency supply of of water was stored in Apollo 14's CM, and an emergency battery, identical to those that powered the LM's descent stage, was placed in the SM. The LM was modified to make the transfer of power from LM to CM easier. + +Other changes included the installation of anti-slosh baffles in the LM descent stage's propellant tanks. This would prevent the low fuel light from coming on prematurely, as had happened on Apollo 11 and 12. Structural changes were made to accommodate the equipment to be used on the lunar surface, including the Modular Equipment Transporter. + +Launch vehicle +The Saturn V used for Apollo 14 was designated SA-509, and was similar to those used on Apollo 8 through 13. At , it was the heaviest vehicle yet flown by NASA, heavier than the launch vehicle for Apollo 13. + +A number of changes were made to avoid pogo oscillations, that had caused an early shutdown of the center J-2 engine on Apollo 13's S-II second stage. These included a helium gas accumulator installed in the liquid oxygen (LOX) line of the center engine, a backup cutoff device for that engine, and a simplified 2-position propellant utilization valve on each of the five J-2 engines. + +ALSEP and other lunar surface equipment +The Apollo Lunar Surface Experiments Package (ALSEP) array of scientific instruments carried by Apollo 14 consisted of the Passive Seismic Experiment (PSE), Active Seismic Experiment (ASE), Suprathermal Ion Detector (SIDE), Cold Cathode Ion Gauge (CCIG), and Charged Particle Lunar Environmental Experiment (CPLEE). Two additional lunar surface experiments not part of the ALSEP were also flown, the Laser Ranging Retro-Reflector (LRRR or LR3), to be deployed in the ALSEP's vicinity, and the Lunar Portable Magnetometer (LPM), to be used by the astronauts during their second EVA. The PSE had been flown on Apollo 12 and 13, the ASE on Apollo 13, the SIDE on Apollo 12, the CCIG on Apollo 12 and 13, and the LRRR on Apollo 11. The LPM was new, but resembled equipment flown on Apollo 12. The ALSEP components flown on Apollo 13 were destroyed when its LM burned up in Earth's atmosphere. +Deployment of the ALSEP, and of the other instruments, each formed one of Apollo 14's mission objectives. + +The PSE was a seismometer, similar to one left on the Moon by Apollo 12, and was to measure seismic activity in the Moon. The Apollo 14 instrument would be calibrated by the impact, after being jettisoned, of the LM's ascent stage, since an object of known mass and velocity would be impacting at a known location on the Moon. The Apollo 12 instrument would also be activated by the spent Apollo 14 S-IVB booster, which would impact the Moon after the mission entered lunar orbit. The two seismometers would, in combination with those left by later Apollo missions, constitute a network of such instruments at different locations on the Moon. + +The ASE would also measure seismic waves. It consisted of two parts. In the first, one of the crew members would deploy three geophones at distances up to from the ALSEP's Central Station, and on his way back from the furthest, fire thumpers every . The second consisted of four mortars (with their launch tubes), of different properties and set to impact at different distances from the experiment. It was hoped that the waves generated from the impacts would provide data about seismic wave transmission in the Moon's regolith. The mortar shells were not to be fired until the astronauts had returned to Earth, and in the event were never fired for fear they would damage other experiments. A similar experiment was successfully deployed, and the mortars launched, on Apollo 16. + +The LPM was to be carried during the second EVA and used to measure the Moon's magnetic field at various points. +The SIDE measured ions on the lunar surface, including from the solar wind. It was combined with the CCIG, which was to measure the lunar atmosphere and detect if it varied over time. The CPLEE measured the particle energies of protons and electrons generated by the Sun that reached the lunar surface. The LRRR acts as a passive target for laser beams, allowing the measurement of the Earth/Moon distance and how it changes over time. The LRRRs from Apollo 11, 14 and 15 are the only experiments left on the Moon by the Apollo astronauts that are still returning data. + +Flown for the first time on Apollo 14 was the Buddy Secondary Life Support System (BSLSS), a set of flexible hoses that would enable Shepard and Mitchell to share cooling water should one of their Primary Life Support System (PLSS) backpacks fail. In such an emergency, the astronaut with the failed equipment would get oxygen from his Oxygen Purge System (OPS) backup cylinder, but the BSLSS would ensure he did not have to use oxygen for cooling, extending the life of the OPS. The OPSs used on Apollo 14 were modified from those used on previous missions in that the internal heaters were removed as unnecessary. + +Water bags were also taken to the lunar surface, dubbed "Gunga Dins", for insertion in the astronauts' helmets, allowing them sips of water during the EVAs. These had been flown on Apollo 13, but Shepard and Mitchell were the first to use them on the Moon. Similarly, Shepard was the first on the lunar surface to wear a spacesuit with commander's stripes: red stripes on arms, legs, and on the helmet, though one had been worn by Lovell on Apollo 13. These were instituted because of the difficulty in telling one spacesuited astronaut from the other in photographs. + +Modular Equipment Transporter + +The Modular Equipment Transporter (MET) was a two-wheeled handcart, used only on Apollo 14, intended to allow the astronauts to take tools and equipment with them, and store lunar samples, without needing to carry them. On later Apollo program missions, the self-propelled Lunar Roving Vehicle (LRV) was flown instead. + +The MET, when deployed for use on the lunar surface, was about long, wide and high. It had pressurized rubber tires wide and in diameter, containing nitrogen and inflated to about . The first use of tires on the Moon, these were developed by Goodyear and were dubbed their XLT (Experimental Lunar Tire) model. Fully loaded, the MET weighed about . Two legs combined with the wheels to provide four-point stability when at rest. + +Mission highlights + +Launch and flight to lunar orbit +Apollo 14 launched from Launch Complex 39-A at KSC at 4:03:02 pm (21:03:02 UTC), January 31, 1971. This followed a launch delay due to weather of 40 minutes and 2 seconds; the first such delay in the Apollo program. The original planned time, 3:23 pm, was at the very start of the launch window of just under four hours; had Apollo 14 not launched during it, it could not have departed until March. Apollo 12 had launched during poor weather and twice been struck by lightning, as a result of which the rules had been tightened. Among those present to watch the launch were U.S. Vice President Spiro T. Agnew and the Prince of Spain, the future King Juan Carlos I. The mission would take a faster trajectory to the Moon than planned, and thus make up the time in flight. Because it had, just over two days after launch, the mission timers would be put ahead by 40 minutes and 3 seconds so that later events would take place at the times scheduled in the flight plan. + +After the vehicle reached orbit, the S-IVB third stage shut down, and the astronauts performed checks of the spacecraft before restarting the stage for translunar injection (TLI), the burn that placed the vehicle on course for the Moon. After TLI, the CSM separated from the S-IVB, and Roosa performed the transposition maneuver, turning it around in order to dock with the LM before the entire spacecraft separated from the stage. Roosa, who had practiced the maneuver many times, hoped to break the record for the least amount of propellant used in docking. But when he gently brought the modules together, the docking mechanism would not activate. He made several attempts over the next two hours, as mission controllers huddled and sent advice. If the LM could not be extracted from its place on the S-IVB, no lunar landing could take place, and with consecutive failures, the Apollo program might end. Mission Control proposed that they try it again with the docking probe retracted, hoping the contact would trigger the latches. This worked, and within an hour the joined spacecraft had separated from the S-IVB. The stage was set on a course to impact the Moon, which it did just over three days later, causing the Apollo 12 seismometer to register vibrations for over three hours. + +The crew settled in for its voyage to Fra Mauro. At 60:30 Ground Elapsed Time, Shepard and Mitchell entered the LM to check its systems; while there they photographed a wastewater dump from the CSM, part of a particle contamination study in preparation for Skylab. Two midcourse corrections were performed on the translunar coast, with one burn lasting 10.19 seconds and one lasting 0.65 seconds. + +Lunar orbit and descent + +At 81:56:40.70 into the mission (February 4 at 1:59:43 am EST; 06:59:43 UTC), the Service Propulsion System engine in the SM was fired for 370.84 seconds to send the craft into a lunar orbit with apocynthion of and pericynthion of . A second burn, at 86:10:52 mission time, sent the spacecraft into an orbit of by . This was done in preparation for the release of the LM Antares. Apollo 14 was the first mission on which the CSM propelled the LM to the lower orbit—though Apollo 13 would have done so had the abort not already occurred. This was done to increase the amount of hover time available to the astronauts, a safety factor since Apollo 14 was to land in rough terrain. + +After separating from the command module in lunar orbit, the LM Antares had two serious problems. First, the LM computer began getting an ABORT signal from a faulty switch. NASA believed the computer might be getting erroneous readings like this if a tiny ball of solder had shaken loose and was floating between the switch and the contact, closing the circuit. The immediate solution – tapping on the panel next to the switch – did work briefly, but the circuit soon closed again. If the problem recurred after the descent engine fired, the computer would think the signal was real and would initiate an auto-abort, causing the ascent stage to separate from the descent stage and climb back into orbit. NASA and the software teams at the Massachusetts Institute of Technology scrambled to find a solution. The software was hard-wired, preventing it from being updated from the ground. The fix made it appear to the system that an abort had already happened, and it would ignore incoming automated signals to abort. This would not prevent the astronauts from piloting the ship, though if an abort became necessary, they might have to initiate it manually. Mitchell entered the changes with minutes to go until planned ignition. + +A second problem occurred during the powered descent, when the LM landing radar failed to lock automatically onto the Moon's surface, depriving the navigation computer of vital information on the vehicle's altitude and vertical descent speed. After the astronauts cycled the landing radar breaker, the unit successfully acquired a signal near . Mission rules required an abort if the landing radar was out at , though Shepard might have tried to land without it. With the landing radar, Shepard steered the LM to a landing which was the closest to the intended target of the six missions that landed on the Moon. + +Lunar surface operations + +Shepard stated, after stepping onto the lunar surface, "And it's been a long way, but we're here." The first EVA began at 9:42 am EST (14:42 UTC) on February 5, 1971, having been delayed by a problem with the communications system which set back the start of the first EVA to five hours after landing. The astronauts devoted much of the first EVA to equipment offloading, deployment of the ALSEP and the US flag, as well as setting up and loading the MET. These activities were televised back to Earth, though the picture tended to degenerate during the latter portion of the EVA. Mitchell deployed the ASE's geophone lines, unreeling and emplacing the two lines leading out from the ALSEP's Central Station. He then fired the thumper explosives, vibrations from which would give scientists back on Earth information about the depth and composition of the lunar regolith. Of the 21 thumpers, five failed to fire. On the way back to the LM, the astronauts collected and documented lunar samples, and took photographs of the area. The first EVA lasted 4 hours, 47 minutes, 50 seconds. + +The astronauts had been surprised by the undulating ground, expecting flatter terrain in the area of the landing, and this became an issue on the second EVA, as they set out, MET in tow, for the rim of Cone crater. The craters that Shepard and Mitchell planned to use for navigational landmarks looked very different on the ground than on the maps they had, based on overhead shots taken from lunar orbit. Additionally, they consistently overestimated the distance they travelled. Mission Control and the CAPCOM, Fred Haise, could see nothing of this, as the television camera remained near the LM, but they worried as the clock ticked on the EVA, and monitored the heavy breathing and rapid heartbeats of the astronauts. They topped one ridge that they expected was the crater rim, only to view more such terrain beyond. Although Mitchell strongly suspected the rim was nearby, they had become physically exhausted from the effort. They were then instructed by Haise to sample where they were and then start moving back towards the LM. Later analysis using the pictures they took determined that they had come within about of the crater's rim. Images from the Lunar Reconnaissance Orbiter (LRO) show the tracks of the astronauts and the MET come to within 30 m of the rim. The difficulties faced by Shepard and Mitchell would emphasize the need for a means of transportation on the lunar surface with a navigation system, which was met by the Lunar Roving Vehicle, already planned to fly on Apollo 15. + +Once the astronauts returned to the vicinity of the LM and were again within view of the television camera, Shepard performed a stunt he had been planning for years in the event he reached the Moon, and which is probably what Apollo 14 is best remembered for. Shepard brought along a Wilson six iron golf club head, which he had modified to attach to the handle of the contingency sample tool, and two golf balls. Shepard took several one-handed swings (due to the limited flexibility of the EVA suit) and exuberantly exclaimed that the second ball went "miles and miles and miles" in the low lunar gravity. Mitchell then threw a lunar scoop handle as if it were a javelin. The "javelin" and one of the golf balls wound up in a crater together, with Mitchell's projectile a bit further. In an interview with Ottawa Golf, Shepard stated the other landed near the ALSEP. The second EVA lasted 4 hours, 34 minutes, 41 seconds. Shepard brought back the club, gave it to the USGA Museum in New Jersey, and had a replica made which he gave to the National Air and Space Museum. In February 2021, to commemorate Apollo 14's 50th anniversary, imaging specialist Andy Saunders, who had previously worked to produce the clearest image of Neil Armstrong on the Moon, produced new, digitally enhanced images that were used to estimate the final resting places of the two balls that Shepard hit - the first landed approximately 24 yards from the "tee", while the second managed 40 yards. + +Lunar samples + +A total of of Moon rocks, or lunar samples, were brought back from Apollo 14. Most are breccias, which are rocks composed of fragments of other, older rocks. Breccias form when the heat and pressure of meteorite impacts fuse small rock fragments together. There were a few basalts that were collected in this mission in the form of clasts (fragments) in breccia. The Apollo 14 basalts are generally richer in aluminum and sometimes richer in potassium than other lunar basalts. Most lunar mare basalts collected during the Apollo program were formed from 3.0 to 3.8 billion years ago. The Apollo 14 basalts were formed 4.0 to 4.3 billion years ago, older than the volcanism known to have occurred at any of the mare locations reached during the Apollo program. + +Some geologists were pleased enough with the close approach to Cone crater to send a case of scotch to the astronauts while they were in post-mission quarantine, though their enthusiasm was tempered by the fact that Shepard and Mitchell had documented few of the samples they brought back, making it hard and sometimes impossible to discern where they came from. Others were less happy; Don Wilhelms wrote in his book on the geological aspects of Apollo, "the golf game did not set well with most geologists in light of the results at Cone crater. The total haul from the rim-flank of Cone ... was 16 Hasselblad photographs (out of a mission total of 417), six rock-size samples heavier than 50 g, and a grand total of 10 kg of samples, 9 kg of which are in one rock (sample 14321 [i.e., Big Bertha]). That is to say, apart from 14321 we have less than 1 kg of rock—962 g to be exact—from what in my opinion is the most important single point reached by astronauts on the Moon." Geologist Lee Silver stated, "The Apollo 14 crews did not have the right attitude, did not learn enough about their mission, had the burden of not having the best possible preflight photography, and they weren't ready." In their sourcebook on Apollo, Richard W. Orloff and David M. Harland doubted that if Apollo 13 had reached the Moon, Lovell, and Haise, given a more distant landing point, could have got as close to Cone crater as Shepard and Mitchell did. + +In January 2019 research showed that Big Bertha, which weighs , has characteristics that make it likely to be a terrestrial (Earth) meteorite. Granite and quartz, which are commonly found on Earth but very rarely found on the Moon, were confirmed to exist on Big Bertha. To find the sample's age, the research team from Curtin University looked at bits of the mineral zircon embedded in its structure. "By determining the age of zircon found in the sample, we were able to pinpoint the age of the host rock at about four billion years old, making it similar to the oldest rocks on Earth," researcher Alexander Nemchin said, adding that "the chemistry of the zircon in this sample is very different from that of every other zircon grain ever analyzed in lunar samples, and remarkably similar to that of zircons found on Earth." This would mean Big Bertha is both the first discovered terrestrial meteorite and the oldest known Earth rock. + +Lunar orbit operations + +Roosa spent almost two days alone aboard Kitty Hawk, performing the first intensive program of scientific observation from lunar orbit, much of which was intended to have been done by Apollo 13. After Antares separated and its crew began preparations to land, Roosa in Kitty Hawk performed an SPS burn to send the CSM to an orbit of approximately , and later a plane change maneuver to compensate for the rotation of the Moon. + +Roosa took pictures from lunar orbit. The Lunar Topographic Camera, also known as the Hycon camera, was supposed to be used to image the surface, including the Descartes Highlands site being considered for Apollo 16, but it quickly developed a fault with the shutter that Roosa could not fix despite considerable help from Houston. Although about half of the photographic targets had to be scrubbed, Roosa was able to obtain photographs of Descartes with a Hasselblad camera and confirm that it was a suitable landing point. Roosa also used the Hasselblad to take photographs of the impact point of Apollo 13's S-IVB near Lansburg B crater. After the mission, troubleshooting found a tiny piece of aluminum contaminating the shutter control circuit, which caused the shutter to operate continuously. + +Roosa was able to see sunlight glinting off Antares and view its lengthy shadow on the lunar surface on Orbit 17; on Orbit 29 he could see the sun reflecting off the ALSEP. He also took astronomical photographs, of the Gegenschein, and of the Lagrangian point of the Sun-Earth system that lies beyond the Earth (L), testing the theory that the Gegenschein is generated by reflections off particles at L. Performing the bistatic radar experiment, he also focused Kitty Hawk VHF and S-band transmitters at the Moon so that they would bounce off and be detected on Earth in an effort to learn more about the depth of the lunar regolith. + +Return, splashdown and quarantine + +Antares lifted off from the Moon at 1:48:42 pm EST (18:48:42 UTC) on February 6, 1971. Following the first direct (first orbit) rendezvous on a lunar landing mission, docking took place an hour and 47 minutes later. Despite concerns based on the docking problems early in the mission, the docking was successful on the first attempt, though the LM's Abort Guidance System, used for navigation, failed just before the two craft docked. After crew, equipment, and lunar samples were transferred to Kitty Hawk, the ascent stage was jettisoned, and impacted the Moon, setting off waves registered by the seismometers from Apollo 12 and 14. + +A trans-earth injection burn took place on February 6 at 8:39:04 pm (February 7 at 01:39:04 UTC) taking 350.8 seconds, during Kitty Hawk 34th lunar revolution. During the trans-earth coast, two tests of the oxygen system were performed, one to ensure the system would operate properly with low densities of oxygen in the tanks, the second to operate the system at a high flow rate, as would be necessary for the in-flight EVAs scheduled for Apollo 15 and later. Additionally, a navigation exercise was done to simulate a return to Earth following a loss of communications. All were successful. During his rest periods on the voyage, Mitchell conducted ESP experiments without NASA's knowledge or sanction, attempting by prearrangement to send images of cards he had brought with him to four people on Earth. He stated after the mission that two of the four had gotten 51 out of 200 correct (the others were less successful), whereas random chance would have dictated 40. +On the final evening in space, the crew conducted a press conference, with the questions submitted to NASA in advance and read to the astronauts by the CAPCOM. + +The command module Kitty Hawk splashed down in the South Pacific Ocean on February 9, 1971, at 21:05 [UTC], approximately south of American Samoa. After recovery by the ship USS New Orleans, the crew was flown to Pago Pago International Airport in Tafuna, then to Honolulu, then to Ellington Air Force Base near Houston in a plane containing a Mobile Quarantine Facility trailer before they continued their quarantine in the Lunar Receiving Laboratory. They remained there until their release from quarantine on February 27, 1971. The Apollo 14 astronauts were the last lunar explorers to be quarantined on their return from the Moon. They were the only Apollo crew to be quarantined both before and after the flight. + +Roosa, who worked in forestry in his youth, took several hundred tree seeds on the flight. These were germinated after the return to Earth, and were widely distributed around the world as commemorative Moon trees. Some seedlings were given to state forestry associations in 1975 and 1976 to mark the United States Bicentennial. + +Mission insignia + +The mission insignia is an oval depicting the Earth and the Moon, and an astronaut pin drawn with a comet trail. The pin is leaving Earth and is approaching the Moon. A gold band around the edge includes the mission and astronaut names. The designer was Jean Beaulieu, who based it on a sketch by Shepard, who had been head of the Astronaut Office and meant the pin to symbolize that through him, the entire corps was in spirit flying to the Moon. + +The backup crew spoofed the patch with its own version, with revised artwork showing a Wile E. Coyote cartoon character depicted as gray-bearded (for Shepard, who was 47 at the time of the mission and the oldest man on the Moon), pot-bellied (for Mitchell, who had a pudgy appearance) and red-furred (for Roosa's red hair), still on the way to the Moon, while Road Runner (for the backup crew) is already on the Moon, holding a U.S. flag and a flag labelled "1st Team". The flight name is replaced by "BEEP BEEP" and the backup crew's names are given. Several of these patches were hidden by the backup crew and found during the flight by the crew in notebooks and storage lockers in both the CSM Kitty Hawk and the LM Antares, and one patch was stored in the MET lunar handcart. One patch, attached to Shepard's PLSS, was worn on the lunar surface, and, mounted on a plaque, was presented by him to Cernan after the mission. + +Spacecraft locations + +The Apollo 14 command module Kitty Hawk is on display at the Apollo/Saturn V Center at the Kennedy Space Center Visitor Complex after being on display at the United States Astronaut Hall of Fame near Titusville, Florida, for several years. At the time of its transfer of ownership from NASA to the Smithsonian in July 1977, it was on display at the facilities of North American Rockwell (the company that had constructed it) in Downey, California. The SM reentered Earth's atmosphere and was destroyed, though there was no tracking or sightings of it. + +The S-IVB booster impacted the Moon on February4 at . The ascent stage of lunar module Antares impacted the Moon on February7, 1971, at 00:45:25.7 UT (February 6, 7:45 pm EST), at . Antares descent stage and the mission's other equipment remain at Fra Mauro at . + +Photographs taken in 2009 by the Lunar Reconnaissance Orbiter were released on July 17, and the Fra Mauro equipment was the most visible Apollo hardware at that time, owing to particularly good lighting conditions.

It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. + +The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. + +At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments collected data on the Moon and its environment using a panoramic camera, a gamma-ray spectrometer, a mapping camera, a laser altimeter, a mass spectrometer, and a lunar subsatellite deployed at the end of the moonwalks. The lunar module returned safely to the command module and, at the end of Apollo 15's 74th lunar orbit, the engine was fired for the journey home. During the return trip, Worden performed the first spacewalk in deep space. The Apollo 15 mission splashed down safely on August7 despite the loss of one of its three parachutes. + +The mission accomplished its goals but was marred by negative publicity the following year when it emerged that the crew had carried unauthorized postal covers to the lunar surface, some of which were sold by a West German stamp dealer. The members of the crew were reprimanded for poor judgment, and did not fly in space again. The mission also saw the collection of the Genesis Rock, thought to be part of the Moon's early crust, and Scott's use of a hammer and a feather to validate Galileo's theory that when there is no air resistance, objects fall at the same rate due to gravity regardless of their mass. + +Background + +In 1962, NASA contracted for the construction of fifteen Saturn V rockets to achieve the Apollo program's goal of a crewed landing on the Moon by 1970; at the time no one knew how many missions this would require. Since success was obtained in 1969 with the sixth SaturnV on Apollo 11, nine rockets remained available for a hoped-for total of ten landings. These plans included a heavier, extended version of the Apollo spacecraft to be used in the last five missions (Apollo 16 through 20). The revamped lunar module would be capable of up to a 75-hour stay, and would carry a Lunar Roving Vehicle to the Moon's surface. The service module would house a package of orbital experiments to gather data on the Moon. In the original plan Apollo 15 was to be the last of the non-extended missions to land in Censorinus crater. But in anticipation of budget cuts, NASA cancelled three landing missions by September 1970. Apollo 15 became the first of three extended missions, known as J missions, and the landing site was moved to Hadley Rille, originally planned for Apollo 19. + +Crew and key Mission Control personnel + +Crew + +Scott was born in 1932 in San Antonio, Texas, and, after spending his freshman year at the University of Michigan on a swimming scholarship, transferred to the United States Military Academy, from which he graduated in 1954. Serving in the Air Force, Scott had received two advanced degrees from MIT in 1962 before being selected as one of the third group of astronauts the following year. He flew in Gemini 8 in 1966 alongside Neil Armstrong and as command module pilot of Apollo 9 in 1969. Worden was born in 1932 in Jackson, Michigan, and like his commander, had attended West Point (class of 1955) and served in the Air Force. Worden earned two master's degrees in engineering from Michigan in 1963. Irwin had been born in 1930 in Pittsburgh, and had attended the United States Naval Academy, graduating in 1951 and serving in the Air Force, receiving a master's degree from Michigan in 1957. Both Worden and Irwin were selected in the fifth group of astronauts (1966), and Apollo 15 would be their only spaceflight. All three future astronauts had attended Michigan, and two had taken degrees from there; it had been the first university to offer an aeronautical engineering program. + +The backup crew was Richard F. Gordon Jr. as commander, Vance D. Brand as command module pilot and Harrison H. Schmitt as lunar module pilot. By the usual rotation of crews, the three would most likely have flown Apollo 18, which was canceled. Brand flew later on the Apollo–Soyuz Test Project and on STS-5, the first operational Space Shuttle mission. With NASA under intense pressure to send a professional scientist to the Moon, Schmitt, a geologist, was selected as LMP of Apollo 17 instead of Joe Engle. +Apollo 15's support crew consisted of astronauts Joseph P. Allen, Robert A. Parker and Karl G. Henize. All three were scientist-astronauts, selected in 1967, as the prime crew felt they needed more assistance with the science than with the piloting. None of the support crew would fly during the Apollo program, waiting until the Space Shuttle program to go into space. + +Mission Control +The flight directors for Apollo 15 were as follows: + Gerry Griffin, Gold team + Milton Windler, Maroon team + Glynn Lunney, Black team + Gene Kranz, White team + +During a mission the capsule communicators (CAPCOMs), always fellow astronauts, were the only people who normally would speak to the crew. For Apollo 15, the CAPCOMs were Allen, Brand, C. Gordon Fullerton, Gordon, Henize, Edgar D. Mitchell, Parker, Schmitt and Alan B. Shepard. + +Planning and training +Schmitt and other scientist-astronauts advocated for a greater place for science on the early Apollo missions. They were often met with disinterest from other astronauts, or found science displaced by higher priorities. Schmitt realized that what was needed was an expert teacher who could fire the astronauts' enthusiasm, and contacted Caltech geologist Lee Silver, whom Schmitt introduced to Apollo 13's commander, Jim Lovell, and to its lunar module pilot, Fred Haise, then in training for their mission. Lovell and Haise were willing to go on a field expedition with Silver, and geology became a significant part of their training. Geologist Farouk El-Baz trained the prime crew's command module pilot, Ken Mattingly to inform his planned observations from lunar orbit. The crew's newly acquired skills mostly went unused, due to the explosion that damaged the Apollo 13 spacecraft, and caused an abort of the mission. Apollo 14's CMP, Stuart Roosa, was enthusiastic about geology, but the mission commander, Shepard, less so. + +Already familiar with the spacecraft as the backup crew for Apollo 12, Scott, Worden and Irwin could devote more of their training time as prime crew for Apollo 15 to geology and sampling techniques. Scott was determined that his crew bring back the maximum amount of scientific data possible, and met with Silver in April 1970 to begin planning the geological training. Schmitt's assignment as Apollo 15's backup LMP made him an insider, and allowed him to spark competition between the prime and backup crews. The cancellation of two Apollo missions in September 1970 transformed Apollo 15 into a J mission, with a longer stay on the lunar surface, and the first Lunar Roving Vehicle (LRV). This change was welcomed by Scott, who according to David West Reynolds in his account of the Apollo program, was "something more than a hotshot pilot. Scott had the spirit of a true explorer", one determined to get the most from the J mission. The additional need for communications, including from planned experiments and the rover, required the near-rebuilding of the Honeysuckle Creek Tracking Station in Australia. + +Geology field trips took place about once a month throughout the crew's 20 months of training. At first, Silver would take the commanders and LMPs from the prime and backup crews to geological sites in Arizona and New Mexico as if for a normal field geology lesson, but closer to launch, these trips became more realistic. Crews began to wear mock-ups of the backpacks they would carry while hiking near the Rio Grande Gorge, and communicate using walkie-talkies to a CAPCOM in a tent. The CAPCOM was accompanied by a geologist unfamiliar with the area who would rely on the astronauts' descriptions to interpret the findings, and familiarized the crew members with describing landscapes to people who could not see them. Considering himself a serious amateur, Scott came to enjoy field geology. + +The decision to land at Hadley came in September 1970. The Site Selection Committee had narrowed the field down to two sites—Hadley Rille, a deep channel on the edge of Mare Imbrium close to the Apennine mountains or the crater Marius, near which were a group of low, possibly volcanic, domes. Although not ultimately his decision, the commander of a mission always held great sway. To David Scott the choice was clear, as Hadley "had more variety. There is a certain intangible quality which drives the spirit of exploration and I felt that Hadley had it. Besides it looked beautiful and usually when things look good they are good." The selection of Hadley was made although NASA lacked high resolution images of the landing site; none had been made as the site was considered too rough to risk one of the earlier Apollo missions. The proximity of the Apennine mountains to the Hadley site required a landing approach trajectory of 26 degrees, far steeper than the 15 degrees in earlier Apollo landings. + +The expanded mission meant that Worden spent much of his time at North American Rockwell's facilities at Downey, California, where the command and service module (CSM) was being built. He undertook a different kind of geology training. Working with El-Baz, he studied maps and photographs of the craters he would pass over while orbiting alone in the CSM. As El-Baz listened and gave feedback, Worden learned how to describe lunar features in a way that would be useful to the scientists who would listen to his transmissions back on Earth. Worden found El-Baz to be an enjoyable and inspiring teacher. Worden usually accompanied his crewmates on their geology field trips, though he was often in an airplane overhead, describing features of the landscape as the plane simulated the speed at which the lunar landscape would pass below the CSM. + +The demands of the training strained both Worden's and Irwin's marriages; each sought Scott's advice, fearing a divorce might endanger their places on the mission as not projecting the image NASA wanted for the astronauts. Scott consulted Director of Flight Crew Operations Deke Slayton, their boss, who stated what was important was that the astronauts do their jobs. Although the Irwins overcame their marital difficulties, the Wordens divorced before the mission. + +Hardware + +Spacecraft + +Apollo 15 used command and service module CSM-112, which was given the call sign Endeavour, named after HMS Endeavour, and lunar module LM-10, call sign Falcon, named after the United States Air Force Academy mascot. Scott explained the choice of the name Endeavour on the grounds that its captain, James Cook had commanded the first purely scientific sea voyage, and Apollo 15 was the first lunar landing mission on which there was a heavy emphasis on science. Apollo 15 took with it a small piece of wood from Cook's ship, while Falcon carried two falcon feathers to the Moon in recognition of the crew's service in the Air Force. Also part of the spacecraft were a Launch Escape System and a Spacecraft-Lunar Module Adapter, numbered SLA-19. + +Technicians at the Kennedy Space Center had some problems with the instruments in the service module's scientific instrument module (SIM) bay. Some instruments were late in arriving, and principal investigators or representatives of NASA contractors sought further testing or to make small changes. Mechanical problems came from the fact the instruments were designed to operate in space, but had to be tested on the surface of the Earth. As such, things like the 7.5 m (24 ft) booms for the mass and gamma ray spectrometers could be tested only using equipment that tried to mimic the space environment, and, in space, the mass spectrometer boom several times did not fully retract. + +On the lunar module, the fuel and oxidizer tanks were enlarged on both the descent and ascent stages, and the engine bell on the descent stage was extended. Batteries and solar cells were added for increased electrical power. In all this increased the weight of the lunar module to , heavier than previous models. + +If Apollo 15 had flown as an H mission, it would have been with CSM-111 and LM-9. That CSM was used by the Apollo–Soyuz Test Project in 1975, but the lunar module went unused and is now at the Kennedy Space Center Visitor Complex. Endeavour is on display at the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Dayton, Ohio, following its transfer of ownership from NASA to the Smithsonian in December 1974. + +Launch vehicle +The Saturn V that launched Apollo 15 was designated SA-510, the tenth flight-ready model of the rocket. As the payload of the rocket was greater, changes were made to the rocket and to its launch trajectory. It was launched in a more southerly direction (80–100 degrees azimuth) than previous missions, and the Earth parking orbit was lowered to . These two changes meant more could be launched. The propellant reserves were reduced and the number of retrorockets on the S-IC first stage (used to separate the spent first stage from the S-II second stage) reduced from eight to four. The four outboard engines of the S-IC would be burned longer and the center engine would also burn longer. Changes were also made to the S-II to dampen pogo oscillations. + +Once all major systems were installed in the SaturnV, it was moved from the Vehicle Assembly Building to the launch site, Launch Complex 39A. During late June and early July 1971, the rocket and Launch Umbilical Tower (LUT) were struck by lightning at least four times. There was no damage to the vehicle, and only minor damage to ground support equipment. + +Space suits +The Apollo 15 astronauts wore redesigned space suits. On all previous Apollo flights, including the non-lunar flights, the commander and lunar module pilot had worn suits with the life support, liquid cooling, and communications connections in two parallel rows of three. On Apollo 15, the new suits, dubbed the "A7LB", had the connectors situated in triangular pairs. This new arrangement, along with the relocation of the entry zipper (which went in an up-down motion on the old suits), to run diagonally from the right shoulder to the left hip, aided in suiting and unsuiting in the cramped confines of the spacecraft. It also allowed for a new waist joint, letting the astronauts bend completely over, and sit on the rover. Upgraded backpacks allowed for longer-duration moonwalks. As in all missions from and after Apollo 13, the commander's suit bore a red stripe on the helmet, arms and legs. + +Worden wore a suit similar to those worn by the Apollo 14 astronauts, but modified to interface with Apollo 15's equipment. Gear needed only for lunar surface EVAs, such as the liquid cooling garment, was not included with Worden's suit, as the only EVA he was expected to do was one to retrieve film cartridges from the SIM bay on the flight home. + +Lunar Roving Vehicle + +A vehicle that could operate on the surface of the Moon had been considered by NASA since the early 1960s. An early version was called MOLAB, which had a closed cabin and would have massed about ; some scaled-down prototypes were tested in Arizona. As it became clear NASA would not soon establish a lunar base, such a large vehicle seemed unnecessary. Still, a rover would enhance the J missions, which were to concentrate on science, though its mass was limited to about and it was not then clear that so light a vehicle could be useful. NASA did not decide to proceed with a rover until May 1969, as Apollo 10, the dress rehearsal for the Moon landing, made its way home from lunar orbit. Boeing received the contract for three rovers on a cost-plus basis; overruns (especially in the navigation system) meant the three vehicles eventually cost a total of $40 million. These cost overruns gained considerable media attention at a time of greater public weariness with the space program, when NASA's budget was being cut. + +The Lunar Roving Vehicle could be folded into a space 5 ft by 20 in (1.5 m by 0.5 m). Unloaded, it weighed 460 lb (209 kg) and when carrying two astronauts and their equipment, 1500 lb (700 kg). Each wheel was independently driven by a horsepower (200 W) electric motor. Although it could be driven by either astronaut, the commander always drove. Travelling at speeds up to 6to 8mph (10to 12km/h), it meant that for the first time the astronauts could travel far afield from their lander and still have enough time to do some scientific experiments. The Apollo 15 rover bore a plaque, reading: "Man's First Wheels on the Moon, Delivered by Falcon, July 30, 1971". During pre-launch testing, the LRV was given additional bracing, lest it collapse if someone sat on it under Earth conditions. + +Particles and Fields Subsatellite + +The Apollo 15 Particles and Fields Subsatellite (PFS-1) was a small satellite released into lunar orbit from the SIM bay just before the mission left orbit to return to Earth. Its main objectives were to study the plasma, particle, and magnetic field environment of the Moon and map the lunar gravity field. Specifically, it measured plasma and energetic particle intensities and vector magnetic fields, and facilitated tracking of the satellite velocity to high precision. A basic requirement was that the satellite acquire fields and particle data everywhere on the orbit around the Moon. As well as measuring magnetic fields, the satellite contained sensors to study the Moon's mass concentrations, or mascons. The satellite orbited the Moon and returned data from August 4, 1971, until January 1973, when, following multiple failures of the subsatellite's electronics, ground support was terminated. It is believed to have crashed into the Moon sometime thereafter. + +Mission highlights + +Launch and outbound trip + +Apollo 15 was launched on July 26, 1971, at 9:34am EDT from the Kennedy Space Center at Merritt Island, Florida. The time of launch was at the very start of the two-hour, 37-minute launch window, which would allow Apollo 15 to arrive at the Moon with the proper lighting conditions at Hadley Rille; had the mission been postponed beyond another window on July 27, it could not have been rescheduled until late August. The astronauts had been awakened five and a quarter hours before launch by Slayton, and after breakfast and suiting up, had been taken to Pad 39A, launch site of all seven attempts at crewed lunar landing, and entered the spacecraft about three hours before launch. There were no unplanned delays in the countdown. + +At 000:11:36 into the mission, the S-IVB engine shut down, leaving Apollo 15 in its planned parking orbit in low Earth orbit. The mission remained there for 2hours and 40 minutes, allowing the crew (and Houston, via telemetry) to check the spacecraft's systems. At 002:50.02.6 into the mission, the S-IVB was restarted for trans-lunar injection (TLI), placing the craft on a path to the Moon. Before TLI, the craft had completed 1.5 orbits around the Earth. + +The command and service module (CSM) and the lunar module remained attached to the nearly-exhausted S-IVB booster. Once trans-lunar injection had been achieved, placing the spacecraft on a trajectory towards the Moon, explosive cords separated the CSM from the booster as Worden operated the CSM's thrusters to push it away. Worden then maneuvered the CSM to dock with the LM (mounted on the end of the S-IVB), and the combined craft was then separated from the S-IVB by explosives. After Apollo 15 separated from the booster, the S-IVB maneuvered away, and, as planned, impacted the Moon about an hour after the crewed spacecraft entered lunar orbit, though due to an error the impact was away from the intended target. The booster's impact was detected by the seismometers left on the Moon by Apollo 12 and Apollo 14, providing useful scientific data. + +There was a malfunctioning light on the craft's service propulsion system (SPS); after considerable troubleshooting, the astronauts did a test burn of the system that also served as a midcourse correction. This occurred about 028:40:00 into the mission. Fearing that the light meant the SPS might unexpectedly fire, the astronauts avoided using the control bank with the faulty light, bringing it online only for major burns, and controlling it manually. After the mission returned, the malfunction proved to be caused by a tiny bit of wire trapped within the switch. + +After purging and renewing the LM's atmosphere to eliminate any contamination, the astronauts entered the LM about 34 hours into the mission, needing to check the condition of its equipment and move in items that would be required on the Moon. Much of this work was televised back to Earth, the camera operated by Worden. The crew discovered a broken outer cover on the Range/Range Rate tapemeter. This was a concern not only because an important piece of equipment, providing information on distance and rate of approach, might not work properly, but because bits of the glass cover were floating around Falcon'''s interior. The tapemeter was supposed to be in a helium atmosphere, but due to the breakage, it was in the LM's oxygen atmosphere. Testing on the ground verified the tapemeter would still work properly, and the crew removed most of the glass using a vacuum cleaner and adhesive tape. + +As yet, there had been only minor problems, but at about 61:15:00 mission time (the evening of July 28 in Houston), Scott discovered a leak in the water system while preparing to chlorinate the water supply. The crew could not tell where it was coming from, and the issue had the potential to become serious. The experts in Houston found a solution, which was successfully implemented by the crew. The water was mopped up with towels, which were then put out to dry in the tunnel between the command module (CM) and lunar module—Scott stated it looked like someone's laundry. + +At 073:31:14 into the mission, a second midcourse correction, with less than a second of burn, was made. Although there were four opportunities to make midcourse corrections following TLI, only two were needed. Apollo 15 approached the Moon on July 29, and the lunar orbit insertion (LOI) burn had to be made using the SPS, on the far side of the Moon, out of radio contact with Earth. If no burn occurred, Apollo 15 would emerge from the lunar shadow and come back in radio contact faster than expected; the continued lack of communication allowed Mission Control to conclude that the burn had taken place. When contact resumed, Scott did not immediately give the particulars of the burn, but spoke admiringly of the beauty of the Moon, causing Alan Shepard, the Apollo 14 commander, who was awaiting a television interview, to grumble, "To hell with that shit, give us details of the burn." The 398.36-second burn took place at 078:31:46.7 into the mission at an altitude of above the Moon, and placed Apollo 15 in an elliptical lunar orbit of . + + Lunar orbit and landing + +On Apollo 11 and 12, the lunar module decoupled from the CSM and descended to a much lower orbit from which the lunar landing attempt commenced; to save fuel in an increasingly heavy lander, beginning with Apollo 14, the SPS in the service module made that burn, known as descent orbit insertion (DOI), with the lunar module still attached to the CSM. The initial orbit Apollo 15 was in had its apocynthion, or high point, over the landing site at Hadley; a burn at the opposite point in the orbit was performed, with the result that Hadley would now be under the craft's pericynthion, or low point. The DOI burn was performed at 082:39:49.09 and took 24.53 seconds; the result was an orbit with apocynthion of and pericynthion of . Overnight between July 29 and 30, as the crew rested, it became apparent to Mission Control that mass concentrations in the Moon were making Apollo 15's orbit increasingly elliptical—pericynthion was by the time the crew was awakened on July 30. This, and uncertainty as to the exact altitude of the landing site, made it desirable that the orbit be modified, or trimmed. Using the craft's RCS thrusters, this took place at 095:56:44.70, lasting 30.40 seconds, and raised the pericynthion to and the apocynthion to . + +As well as preparing the lunar module for its descent, the crew continued observations of the Moon (including of the landing site at Hadley) and provided television footage of the surface. Then, Scott and Irwin entered the lunar module in preparation for the landing attempt. Undocking was planned for 100:13:56, over the far side of the Moon, but nothing happened when separation was attempted. After analyzing the problem, the crew and Houston decided the probe instrumentation umbilical was likely loose or disconnected; Worden went into the tunnel connecting the command and lunar modules and determined this was so, seating it more firmly. With the problem resolved, Falcon separated from Endeavour at 100:39:16.2, about 25 minutes late, at an altitude of . Worden in Endeavour executed a SPS burn at 101:38:58.98 to send Endeavour to an orbit of by in preparation for his scientific work. + +Aboard Falcon, Scott and Irwin prepared for powered descent initiation (PDI), the burn that was to place them on the lunar surface, and, after Mission Control gave them permission, they initiated PDI at 104:30:09.4 at an altitude of , slightly higher than planned. During the first part of the descent, Falcon was aligned so the astronauts were on their backs and thus could not see the lunar surface below them, but after the craft made a pitchover maneuver, they were upright and could see the surface in front of them. Scott, who as commander performed the landing, was confronted with a landscape that did not at first seem to resemble what he had seen during simulations. Part of this was due to an error in the landing path of some , of which CAPCOM Ed Mitchell informed the crew prior to pitchover; part because the craters Scott had relied on in the simulator were difficult to make out under lunar conditions, and he initially could not see Hadley Rille. He concluded that they were likely to overshoot the planned landing site, and, once he could see the rille, started maneuvering the vehicle to move the computer's landing target back towards the planned spot, and looked for a relatively smooth place to land. + +Below about , Scott could see nothing of the surface because of the quantities of lunar dust being displaced by Falcons exhaust. Falcon had a larger engine bell than previous LMs, in part to accommodate a heavier load, and the importance of shutting down the engine at initial contact rather than risk "blowback", the exhaust reflecting off the lunar surface and going back into the engine (possibly causing an explosion) had been impressed on the astronauts by mission planners. Thus, when Irwin called "Contact", indicating that one of the probes on the landing leg extensions had touched the surface, Scott immediately shut off the engine, letting the lander fall the remaining distance to the surface. Already moving downward at about per second, Falcon dropped from a height of . Scott's speed resulted in what was likely the hardest lunar landing of any of the crewed missions, at about per second, causing a startled Irwin to yell "Bam!" Scott had landed Falcon on the rim of a small crater he could not see, and the lander settled back at an angle of 6.9 degrees and to the left of 8.6 degrees. Irwin described it in his autobiography as the hardest landing he had ever been in, and he feared that the craft would keep tipping over, forcing an immediate abort. + +Falcon landed at 104:42:29.3 (22:16:29 GMT on July 30), with approximately 103 seconds of fuel remaining, about from the planned landing site. After Irwin's exclamation, Scott reported, "Okay, Houston. The Falcon is on the Plain at Hadley." Once within the planned landing zone, the increased mobility provided by the Lunar Roving Vehicle made unnecessary any further maneuvering. + + Lunar surface + + Stand-up EVA and first EVA + +With Falcon due to remain on the lunar surface for almost three days, Scott deemed it important to maintain the circadian rhythm they were used to, and as they had landed in the late afternoon, Houston time, the two astronauts were to sleep before going onto the surface. But the time schedule allowed Scott to open the lander's top hatch (usually used for docking) and spend a half hour looking at their surroundings, describing them, and taking photographs. Lee Silver had taught him the importance of going to a high place to survey a new field site, and the top hatch served that purpose. Deke Slayton and other managers were initially opposed due to the oxygen that would be lost, but Scott got his way. During the only stand-up extravehicular activity (EVA) ever performed through the LM's top hatch on the lunar surface, Scott was able to make plans for the following day's EVA. He offered Irwin a chance to look out as well, but this would have required rearranging the umbilicals connecting Irwin to Falcon'''s life support system, and he declined. After repressurizing the spacecraft, Scott and Irwin removed their space suits for sleep, becoming the first astronauts to doff their suits while on the Moon. + +Throughout the sleep period Mission Control in Houston monitored a slow but steady oxygen loss. Scott and Irwin eventually were awakened an hour early, and the source of the problem was found to be an open valve on the urine transfer device. In post-mission debriefing, Scott recommended that future crews be woken at once under similar circumstances. After the problem was solved, the crew began preparation for the first Moon walk. + +After donning their suits and depressurizing the cabin, Scott and Irwin began their first full EVA, becoming the seventh and eighth humans, respectively, to walk on the Moon. They began deploying the lunar rover, stored folded up in a compartment of Falcons descent stage, but this proved troublesome due to the slant of the lander. The experts in Houston suggested lifting the front end of the rover as the astronauts pulled it out, and this worked. Scott began a system checkout. One of the batteries gave a zero voltage reading, but this was only an instrumentation problem. A greater concern was that the front wheel steering would not work. However, the rear wheel steering was sufficient to maneuver the vehicle. Completing his checkout, Scott said "Okay. Out of detent; we're moving", maneuvering the rover away from Falcon in mid-sentence. These were the first words uttered by a human while driving a vehicle on the Moon. The rover carried a television camera, controlled remotely from Houston by NASA's Ed Fendell. The resolution was not high compared to the still photographs that would be taken, but the camera allowed the geologists on Earth to indirectly participate in Scott and Irwin's activities. + +The rille was not visible from the landing site, but as Scott and Irwin drove over the rolling terrain, it came into view. They were able to see Elbow crater, and they began to drive in that direction. Reaching Elbow, a known location, allowed Mission Control to backtrack and get closer to pinpointing the location of the lander. The astronauts took samples there, and then drove to another crater on the flank of Mons Hadley Delta, where they took more. After concluding this stop, they returned to the lander to drop off their samples and prepare to set up the Apollo Lunar Surface Experiments Package (ALSEP), the scientific instruments that would remain when they left. Scott had difficulty drilling the holes required for the heat flow experiment, and the work was not completed when they had to return to the lander. The first EVA lasted 6hours and 32 minutes. + +Second and third EVAs + +The rover's front steering, inoperative during the first EVA, worked during the second and third ones. The target of the second EVA, on August 1, was the slope of Mons Hadley Delta, where the pair sampled boulders and craters along the Apennine Front. They spent an hour at Spur crater, during which the astronauts collected a sample dubbed the Genesis Rock. This rock, an anorthosite, is believed to be part of the early lunar crust—the hope of finding such a specimen had been one reason the Hadley area had been chosen. Once back at the landing site, Scott continued to try to drill holes for experiments at the ALSEP site, with which he had struggled the day before. After conducting soil-mechanics experiments and raising the U.S. flag, Scott and Irwin returned to the LM. EVA2 lasted 7hours and 12 minutes. + +Although Scott had eventually been successful at drilling the holes, he and Irwin had been unable to retrieve a core sample, and this was an early order of business during EVA 3, their third and final moonwalk. Time that could have been devoted to geology ticked away as Scott and Irwin attempted to pull it out. Once it had been retrieved, more time passed as they attempted to break the core into pieces for transport to Earth. Hampered by an incorrectly mounted vise on the rover, they eventually gave up on this—the core would be transported home with one segment longer than planned. Scott wondered if the core was worth the amount of time and effort invested, and the CAPCOM, Joe Allen, assured him it was. The core proved one of the most important items brought back from the Moon, revealing much about its history, but the expended time meant the planned visit to a group of hills known as the North Complex had to be scrubbed. Instead, the crew again ventured to the edge of Hadley Rille, this time to the northwest of the immediate landing site. + +Once the astronauts were beside the LM, Scott used a kit provided by the Postal Service to cancel a first day cover of two stamps being issued on August 2, the current date. Scott then performed an experiment in view of the television camera, using a falcon feather and hammer to demonstrate Galileo's theory that all objects in a given gravity field fall at the same rate, regardless of mass, in the absence of aerodynamic drag. He dropped the hammer and feather at the same time; because of the negligible lunar atmosphere, there was no drag on the feather, which hit the ground at the same time as the hammer. This was Joe Allen's idea (he also served as CAPCOM during it) and was part of an effort to find a memorable popular science experiment to do on the Moon along the lines of Shepard's hitting of golf balls. The feather was most likely from a female gyrfalcon (a type of falcon), a mascot at the United States Air Force Academy. + +Scott then drove the rover to a position away from the LM, where the television camera could be used to observe the lunar liftoff. Near the rover, he left a small aluminum statuette called Fallen Astronaut, along with a plaque bearing the names of 14 known American astronauts and Soviet cosmonauts who had died in the furtherance of space exploration. The memorial was left while the television camera was turned away; he told Mission Control he was doing some cleanup activities around the rover. Scott disclosed the memorial in a post-flight news conference. He also placed a Bible on the control panel of the rover before leaving it for the last time to enter the LM. + +The EVA lasted 4 hours, 49 minutes and 50 seconds. In total, the two astronauts spent 18 hours outside the LM and collected approximately of lunar samples. + +Command module activities + +After the departure of Falcon, Worden in Endeavour executed a burn to take the CSM to a higher orbit. While Falcon was on the Moon, the mission effectively split, Worden and the CSM being assigned their own CAPCOM and flight support team. + +Worden got busy with the tasks that were to occupy him for much of the time he spent in space alone: photography and operating the instruments in the SIM bay. The door to the SIM bay had been explosively jettisoned during the translunar coast. Filling previously-unused space in the service module, the SIM bay contained a gamma-ray spectrometer, mounted on the end of a boom, an X-ray spectrometer and a laser altimeter, which failed part way through the mission. Two cameras, a stellar camera and a metric camera, together comprised the mapping camera, which was complemented by a panoramic camera, derived from spy technology. The altimeter and cameras permitted the exact time and location from which pictures were taken to be determined. Also present were an alpha particle spectrometer, which could be used to detect evidence of lunar volcanism, and a mass spectrometer, also on a boom in the hope it would be unaffected by contamination from the ship. The boom would prove troublesome, as Worden would not always be able to get it to retract. + +Endeavour was slated to pass over the landing site at the moment of planned landing, but Worden could not see Falcon and did not spot it until a subsequent orbit. He also exercised to avoid muscle atrophy, and Houston kept him up to date on Scott and Irwin's activities on the lunar surface. The panoramic camera did not operate perfectly, but provided enough images that no special adjustment was made. Worden took many photographs through the command module's windows, often with shots taken at regular intervals. His task was complicated by the lack of a working mission timer in the Lower Equipment Bay of the command module, as its circuit breaker had popped en route to the Moon. Worden's observations and photographs would inform the decision to send Apollo 17 to Taurus-Littrow to search for evidence of volcanic activity. There was a communications blackout when the CSM passed over the far side of the Moon from Earth; Worden greeted each resumption of contact with the words, "Hello, Earth. Greetings from Endeavour", expressed in different languages. Worden and El-Baz had come up with the idea, and the geology instructor had aided the astronaut in accumulating translations. + +Results from the SIM bay experiments would include the conclusion, from data gathered by the X-ray spectrometer, that there was greater fluorescent X-ray flux than anticipated, and that the lunar highlands were richer in aluminum than were the mares. Endeavour was in a more inclined orbit than previous crewed missions, and Worden saw features that were not known previously, supplementing photographs with thorough descriptions. + +By the time Scott and Irwin were ready to take off from the lunar surface and return to Endeavour, the CSM's orbit had drifted due to the rotation of the Moon, and a plane change burn was required to ensure that the CSM's orbit would be in the same plane as that of the LM once it took off from the Moon. Worden accomplished the 18-second burn with the SPS. + +Return to Earth + +Falcon lifted off the Moon at 17:11:22 GMT on August2 after 66 hours and 55 minutes on the lunar surface. Docking with the CSM took place just under two hours later. After the astronauts transferred samples and other items from the LM to the CSM, the LM was sealed off, jettisoned, and intentionally crashed into the lunar surface, an impact registered by the seismometers left by Apollo 12, 14 and 15. The jettison proved difficult because of problems getting airtight seals, requiring a delay in discarding the LM. After the jettison, Slayton came on the loop to recommend the astronauts take sleeping pills, or at least that Scott and Irwin do so. Scott as mission commander refused to allow it, feeling there was no need. During the EVAs, the doctors had noticed irregularities in both Scott's and Irwin's heartbeats, but the crew were not informed during the flight. Irwin had heart problems after retiring as an astronaut and died in 1991 of a heart attack; Scott felt that he as commander should have been informed of the biomedical readings. NASA doctors at the time theorized the heart readings were due to potassium deficiency, due to their hard work on the surface and inadequate resupply through liquids. + +The crew spent the next two days working on orbital science experiments, including more observations of the Moon from orbit and releasing the subsatellite. Endeavour departed lunar orbit with another burn of the SPS engine of 2minutes 21 seconds at 21:22:45 GMT on August4. The next day, during the return to Earth, Worden performed a 39-minute EVA to retrieve film cassettes from the service module's scientific instrument module (SIM) bay, with assistance from Irwin who remained at the command module's hatch. At approximately 171,000 nautical miles (197,000 mi; 317,000 km) from Earth, it was the first "deep space" EVA in history, performed at great distance from any planetary body. As of , it remains one of only three such EVAs, all performed during Apollo's J missions under similar circumstances. Later that day, the crew set a record for the longest Apollo flight to that point. + +On approach to Earth on August7, the service module was jettisoned, and the command module reentered the Earth's atmosphere. Although one of the three parachutes on the CM failed after deploying, likely due to damage as the spacecraft vented fuel, only two were required for a safe landing (one extra for redundancy). Upon landing in the North Pacific Ocean, the CM and crew were recovered and taken aboard the recovery ship, , after a mission lasting 12 days, 7hours, 11 minutes and 53 seconds. + +Assessment +The mission objectives for Apollo 15 were to "perform selenological inspection, survey, and sampling of materials and surface features in a pre-selected area of the Hadley–Apennine region. Emplace and activate surface experiments. Evaluate the capability of the Apollo equipment to provide extended lunar surface stay time, increased extravehicular operations, and surface mobility. [and] Conduct inflight experiments and photographic tasks from lunar orbit." It achieved all those objectives. The mission also completed a long list of other tasks, including experiments. One of the photographic objectives, to obtain images of the gegenschein from lunar orbit, was not completed, as the camera was not pointed at the proper spot in the sky. According to the conclusions in the Apollo 15 Mission Report, the journey "was the fourth lunar landing and resulted in the collection of a wealth of scientific information. The Apollo system, in addition to providing a means of transportation, excelled as an operational scientific facility." + +Apollo 15 saw an increase in public interest in the Apollo program, in part due to fascination with the LRV, as well as the attractiveness of the Hadley Rille site and the increased television coverage. +According to David Woods in the Apollo Lunar Flight Journal, + +Controversies + +Despite the successful mission, the careers of the crew were tarnished by a deal they had made before the flight to carry postal covers to the Moon in exchange for about $7,000 each, which they planned to set aside for their children. Walter Eiermann, who had many professional and social contacts with NASA employees and the astronaut corps, served as intermediary between the astronauts and a West German stamp dealer, Hermann Sieger, and Scott carried about 400 covers onto the spacecraft; they were subsequently transferred into Falcon and remained inside the lander during the astronauts' activities on the surface of the Moon. After the return to Earth, 100 of the covers were given to Eiermann, who passed them on to Sieger, receiving a commission. No permission had been received from Slayton to carry the covers, as required. + +The 100 covers were put on sale to Sieger's customers in late 1971 at a price of about $1,500 each. After receiving the agreed payments, the astronauts returned them, and accepted no compensation. In April 1972, Slayton learned that unauthorized covers had been carried, and removed the three as the backup crew for Apollo 17. The matter became public in June 1972 and the three astronauts were reprimanded for poor judgment; none ever flew in space again. During the investigation, the astronauts had surrendered those covers still in their possession; after Worden filed suit, they were returned in 1983, something Slate magazine deemed an exoneration. + +Another controversy surrounding the Fallen Astronaut statuette that Scott had left on the Moon, arose later. Before the mission, Scott had made a verbal agreement with Belgian artist Paul Van Hoeydonck to sculpt the statuette. Scott's intent, in keeping with NASA's strict policy against commercial exploitation of the US government's space program, was for a simple memorial with a minimum of publicity, keeping the artist anonymous, no commercial replicas being made except for a single copy for public exhibit at the National Air and Space Museum commissioned after the sculpture's public disclosure during the post-flight press conference. Van Hoeydonck claims to have had a different understanding of the agreement, by which he would have received recognition as the creator of a tribute to human space exploration, with rights to sell replicas to the public. Under pressure from NASA, Van Hoeydonck canceled a plan to publicly sell 950 signed copies. + +During the congressional hearings into the postal covers and Fallen Astronaut matters, two Bulova timepieces taken on the mission by Scott were also matters of controversy. Before the mission, Scott had been introduced to Bulova's representative, General James McCormack by Apollo 8 commander Frank Borman. Bulova had been seeking to have its timepieces taken on Apollo missions, but after evaluation, NASA had selected Omega watches instead. Scott brought the Bulova timepieces on the mission, without disclosing them to Slayton. During Scott's second EVA, the crystal on his NASA standard issue Omega Speedmaster watch popped off, and, during the third EVA, he used a Bulova watch. The Bulova Chronograph Model #88510/01 that Scott wore on the lunar surface was a prototype, given to him by the Bulova Company, and it is the only privately owned watch to have been worn while walking on the lunar surface. There are images of him wearing this watch, when he saluted the American flag on the Moon, with the Hadley Delta expanse in the background. In 2015, the watch sold for $1.625 million, which makes it one of the most expensive astronaut-owned artifact ever sold at auction and one of the most expensive watches sold at auction. + +Mission insignia + +The Apollo 15 mission patch carries Air Force motifs, a nod to the crew's service there, just as the Apollo 12 all-Navy crew's patch had featured a sailing ship. The circular patch features stylized red, white and blue birds flying over Hadley Rille. Immediately behind the birds, a line of craters forms the Roman numeral XV. The Roman numerals were hidden in emphasized outlines of some craters after NASA insisted that the mission number be displayed in Arabic numerals. The artwork is circled in red, with a white band giving the mission and crew names and a blue border. Scott contacted fashion designer Emilio Pucci to design the patch, who came up with the basic idea of the three-bird motif on a square patch. + +The crew changed the shape to round and the colors from blues and greens to a patriotic red, white and blue. Worden stated that each bird also represented an astronaut, white being his own color (and as Command Module Pilot, uppermost), Scott being the blue bird and Irwin the red. The colors matched Chevrolet Corvettes leased by the astronauts at KSC; a Florida car dealer had, since the time of Project Mercury, been leasing Chevrolets to astronauts for $1 and later selling them to the public. The astronauts were photographed with the cars and the training LRV for the June 11, 1971, edition of Life magazine. + +Visibility from space +The halo area of the Apollo 15 landing site, created by the LM's exhaust plume, was observed by a camera aboard the Japanese lunar orbiter SELENE and confirmed by comparative analysis of photographs in May 2008. This corresponds well to photographs taken from the Apollo 15 command module showing a change in surface reflectivity due to the plume, and was the first visible trace of crewed landings on the Moon seen from space since the close of the Apollo program. + +Gallery + +Still images + +Multimedia + +See also + + List of artificial objects on the Moon + List of spacewalks and moonwalks 1965–1999 + +Notes + +References + +Apollo Lunar Flight Journal + +Apollo Lunar Surface Journal + +Bibliography + +External links + + Apollo 15 Preliminary Science Report (1972) by the Manned Spacecraft Center + Apollo 15 Traverses, 41B4S4(25), Lunar Photomap at Lunar and Planetary Institute + 1975 summary report by NASA + 1972 NASA press releases at collectSPACE + Moonport: A History of Apollo Launch Facilities and Operations, a 1978 book published by NASA + Part 1 and part 2 of Apollo 15: In the Mountains of the Moon, a NASA documentary film on the Apollo 15 mission, at the Internet Archive + 2011 podcast interview with AstrotalkUK + 2016 interview with Worden at Medium + + +James Irwin +David Scott +Alfred Worden +Articles containing video clips +Apollo program missions +Extravehicular activity +Lunar rovers +Crewed missions to the Moon +Sample return missions +Soft landings on the Moon +Spacecraft which reentered in 1971 +Spacecraft launched in 1971 +June 1971 events +Spacecraft launched by Saturn rockets +1971 on the Moon +Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's "J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved not to be the case. + +The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to Earth, before deciding the problem could be overcome. Although they permitted the lunar landing, NASA had the astronauts return from the mission one day earlier than planned. + +After flying the lunar module to the Moon's surface on April 21, Young and Duke spent 71 hours—just under three days—on the lunar surface, during which they conducted three extravehicular activities or moonwalks, totaling 20 hours and 14 minutes. The pair drove the lunar rover, the second used on the Moon, for . On the surface, Young and Duke collected of lunar samples for return to Earth, including Big Muley, the largest Moon rock collected during the Apollo missions. During this time Mattingly orbited the Moon in the command and service module (CSM), taking photos and operating scientific instruments. Mattingly, in the command module, spent 126 hours and 64 revolutions in lunar orbit. After Young and Duke rejoined Mattingly in lunar orbit, the crew released a subsatellite from the service module (SM). During the return trip to Earth, Mattingly performed a one-hour spacewalk to retrieve several film cassettes from the exterior of the service module. Apollo 16 returned safely to Earth on April 27, 1972. + +Crew and key Mission Control personnel + +John Young, the mission commander, was 41 years old and a captain in the Navy at the time of Apollo 16. Becoming an astronaut in 1962 as part of the second group to be selected by NASA, he flew in Gemini 3 with Gus Grissom in 1965, becoming the first American not of the Mercury Seven to fly in space. He thereafter flew in Gemini 10 (1966) with Michael Collins and as command module pilot of Apollo 10 (1969). With Apollo 16, he became the second American, after Jim Lovell, to fly in space four times. + +Thomas Kenneth "Ken" Mattingly, the command module pilot, was 36 years old and a lieutenant commander in the Navy at the time of Apollo 16. Mattingly had been selected in NASA's fifth group of astronauts in 1966. He was a member of the support crew for Apollo 8 and Apollo 9. Mattingly then undertook parallel training with Apollo 11's backup CMP, William Anders, who had announced his resignation from NASA effective at the end of July 1969 and would thus be unavailable if the first lunar landing mission was postponed. Had Anders left NASA before Apollo 11 flew, Mattingly would have taken his place on the backup crew. + +Mattingly had originally been assigned to the prime crew of Apollo 13, but was exposed to rubella through Charles Duke, at that time with Young on Apollo 13's backup crew; Duke had caught it from one of his children. Mattingly never contracted the illness, but three days before launch was removed from the crew and replaced by his backup, Jack Swigert. Duke, also a Group 5 astronaut and a space rookie, had served on the support crew of Apollo 10 and was a capsule communicator (CAPCOM) for Apollo 11. A lieutenant colonel in the Air Force, Duke was 36 years old at the time of Apollo 16, which made him the youngest of the twelve astronauts who walked on the Moon during Apollo as of the time of the mission. All three men were announced as the prime crew of Apollo 16 on March 3, 1971. + +Apollo 16's backup crew consisted of Fred W. Haise Jr. (commander, who had flown on Apollo 13), Stuart A. Roosa (CMP, who had flown on Apollo 14) and Edgar D. Mitchell (LMP, also Apollo 14). Although not officially announced, Director of Flight Crew Operations Deke Slayton, the astronauts' supervisor, had originally planned to have a backup crew of Haise as commander, William R. Pogue (CMP) and Gerald P. Carr (LMP), who were targeted for the prime crew assignment on Apollo 19. However, after the cancellations of Apollos 18 and 19 were announced in September 1970, it made more sense to use astronauts who had already flown lunar missions as backups, rather than training others on what would likely be a dead-end assignment. Subsequently, Roosa and Mitchell were assigned to the backup crew, while Pogue and Carr were reassigned to the Skylab program where they flew on Skylab 4. + +For projects Mercury and Gemini, a prime and a backup crew had been designated, but for Apollo, a third group of astronauts, known as the support crew, was also designated. Slayton created the support crews early in the Apollo Program on the advice of Apollo crew commander James McDivitt, who would lead Apollo 9. McDivitt believed that, with preparation going on in facilities across the U.S., meetings that needed a member of the flight crew would be missed. Support crew members were to assist as directed by the mission commander. Usually low in seniority, they assembled the mission's rules, flight plan, and checklists, and kept them updated. For Apollo 16, they were: Anthony W. England, Karl G. Henize, Henry W. Hartsfield Jr., Robert F. Overmyer and Donald H. Peterson. + +Flight directors were Pete Frank and Philip Shaffer, first shift, Gene Kranz and Donald R. Puddy, second shift, and Gerry Griffin, Neil B. Hutchinson and Charles R. Lewis, third shift. Flight directors during Apollo had a one-sentence job description: "The flight director may take any actions necessary for crew safety and mission success." CAPCOMs were Haise, Roosa, Mitchell, James B. Irwin, England, Peterson, Hartsfield, and C. Gordon Fullerton. + +Mission insignia and call signs + +The insignia of Apollo 16 is dominated by a rendering of an American eagle and a red, white and blue shield, representing the people of the United States, over a gray background representing the lunar surface. Overlaying the shield is a gold NASA vector, orbiting the Moon. On its gold-outlined blue border, there are 16 stars, representing the mission number, and the names of the crew members: Young, Mattingly, Duke. The insignia was designed from ideas originally submitted by the crew of the mission, by Barbara Matelski of the graphics shop at the Manned Spacecraft Center in Houston. + +Young and Duke chose "Orion" for the lunar module's call sign, while Mattingly chose "Casper" for the command and service module. According to Duke, he and Young chose "Orion" for the LM because they wanted something connected with the stars. Orion is one of the brightest constellations as seen from Earth, and one visible to the astronauts throughout their journey. Duke also stated, "it is a prominent constellation and easy to pronounce and transmit to Mission Control". Mattingly said he chose "Casper", evoking Casper the Friendly Ghost, because "there are enough serious things in this flight, so I picked a non-serious name." + +Planning and training + +Landing site selection +Apollo 16 was the second of Apollo's J missions, featuring the use of the Lunar Roving Vehicle, increased scientific capability, and three-day lunar surface stays. As Apollo 16 was the penultimate mission in the Apollo program and there was no major new hardware or procedures to test on the lunar surface, the last two missions (the other being Apollo 17) presented opportunities for astronauts to clear up some of the uncertainties in understanding the Moon's characteristics. Scientists sought information on the Moon's early history, which might be obtained from its ancient surface features, the lunar highlands. Previous Apollo expeditions, including Apollo 14 and Apollo 15, had obtained samples of pre-mare lunar material, likely thrown from the highlands by meteorite impacts. These were dated from before lava began to upwell from the Moon's interior and flood the low areas and basins. Nevertheless, no Apollo mission had actually visited the lunar highlands. + +Apollo 14 had visited and sampled a ridge of material ejected by the impact that created the Mare Imbrium impact basin. Likewise, Apollo 15 had also sampled material in the region of Imbrium, visiting the basin's edge. Because the Apollo 14 and Apollo 15 landing sites were closely associated with the Imbrium basin, there was still the chance that different geologic processes were prevalent in areas of the lunar highlands far from Mare Imbrium. Scientist Dan Milton, studying photographs of the highlands from Lunar Orbiter photographs, saw an area in the Descartes region of the Moon with unusually high albedo that he theorized might be due to volcanic rock; his theory quickly gained wide support. Several members of the scientific community noted that the central lunar highlands resembled regions on Earth that were created by volcanism processes and hypothesized the same might be true on the Moon. They hoped scientific output from the Apollo 16 mission would provide an answer. Some scientists advocated for a landing near the large crater, Tycho, but its distance from the lunar equator and the fact that the lunar module would have to approach over very rough terrain ruled it out. + +The Ad Hoc Apollo Site Evaluation Committee met in April and May 1971 to decide the Apollo 16 and 17 landing sites; it was chaired by Noel Hinners of Bellcomm. There was consensus the final landing sites should be in the lunar highlands, and among the sites considered for Apollo 16 were the Descartes Highlands region west of Mare Nectaris and the crater Alphonsus. The considerable distance between the Descartes site and previous Apollo landing sites would also be beneficial for the network of seismometers, deployed on each landing mission beginning with Apollo 12. + +At Alphonsus, three scientific objectives were determined to be of primary interest and paramount importance: the possibility of old, pre-Imbrium impact material from within the crater's wall, the composition of the crater's interior and the possibility of past volcanic activity on the floor of the crater at several smaller "dark halo" craters. Geologists feared, however, that samples obtained from the crater might have been contaminated by the Imbrium impact, thus preventing Apollo 16 from obtaining samples of pre-Imbrium material. There also remained the distinct possibility that this objective would have already been satisfied by the Apollo 14 and Apollo 15 missions, as the Apollo 14 samples had not yet been completely analyzed and samples from Apollo 15 had not yet been obtained. + +On June 3, 1971, the site selection committee decided to target the Apollo 16 mission for the Descartes site. Following the decision, the Alphonsus site was considered the most likely candidate for Apollo 17, but was eventually rejected. With the assistance of orbital photography obtained on the Apollo 14 mission, the Descartes site was determined to be safe enough for a crewed landing. The specific landing site was between two young impact craters, North Ray and South Ray craters – in diameter, respectively – which provided "natural drill holes" which penetrated through the lunar regolith at the site, thus leaving exposed bedrock that could be sampled by the crew. + +After the selection, mission planners made the Descartes and Cayley formations, two geologic units of the lunar highlands, the primary sampling interest of the mission. It was these formations that the scientific community widely suspected were formed by lunar volcanism, but this hypothesis was proven incorrect by the composition of lunar samples from the mission. + +Training + +In addition to the usual Apollo spacecraft training, Young and Duke, along with backup commander Fred Haise, underwent an extensive geological training program that included several field trips to introduce them to concepts and techniques they would use in analyzing features and collecting samples on the lunar surface. During these trips, they visited and provided scientific descriptions of geologic features they were likely to encounter. The backup LMP, Mitchell, was unavailable during the early part of the training, occupied with tasks relating to Apollo 14, but by September 1971 had joined the geology field trips. Before that, Tony England (a member of the support crew and the lunar EVA CAPCOM) or one of the geologist trainers would train alongside Haise on geology field trips. + +Since Descartes was believed to be volcanic, a good deal of this training was geared towards volcanic rocks and features, but field trips were made to sites featuring other sorts of rock. As Young later commented, the non-volcanic training proved more useful, given that Descartes did not prove to be volcanic. In July 1971, they visited Sudbury, Ontario, Canada, for geology training exercises, the first time U.S. astronauts trained in Canada. The Apollo 14 landing crew had visited a site in West Germany; geologist Don Wilhelms related that unspecified incidents there had caused Slayton to rule out further European training trips. Geologists chose Sudbury because of a wide crater created about 1.8 billion years ago by a large meteorite. The Sudbury Basin shows evidence of shatter cone geology, familiarizing the Apollo crew with geologic evidence of a meteorite impact. During the training exercises the astronauts did not wear space suits, but carried radio equipment to converse with each other and England, practicing procedures they would use on the lunar surface. By the end of the training, the field trips had become major exercises, involving up to eight astronauts and dozens of support personnel, attracting coverage from the media. For the exercise at the Nevada Test Site, where the massive craters left by nuclear explosions simulated the large craters to be found on the Moon, all participants had to have security clearance and a listed next-of-kin, and an overflight by CMP Mattingly required special permission. + +In addition to the field geology training, Young and Duke also trained to use their EVA space suits, adapt to the reduced lunar gravity, collect samples, and drive the Lunar Roving Vehicle. The fact that they had been backups for Apollo 13, planned to be a landing mission, meant that they could spend about 40 percent of their time training for their surface operations. They also received survival training and prepared for technical aspects of the mission. The astronauts spent much time studying the lunar samples brought back by earlier missions, learning about the instruments to be carried on the mission, and hearing what the principal investigators in charge of those instruments expected to learn from Apollo 16. This training helped Young and Duke, while on the Moon, quickly realize that the expected volcanic rocks were not there, even though the geologists in Mission Control initially did not believe them. Much of the training—according to Young, 350 hours—was conducted with the crew wearing space suits, something that Young deemed vital, allowing the astronauts to know the limitations of the equipment in doing their assigned tasks. Mattingly also received training in recognizing geological features from orbit by flying over the field areas in an airplane, and trained to operate the Scientific Instrument Module from lunar orbit. + +Equipment + +Launch vehicle +The launch vehicle which took Apollo 16 to the Moon was a Saturn V, designated as AS-511. This was the eleventh Saturn V to be flown and the ninth used on crewed missions. Apollo 16's Saturn V was almost identical to Apollo 15's. One change that was made was the restoration of four retrorockets to the S-IC first stage, meaning there would be a total of eight, as on Apollo 14 and earlier. The retrorockets were used to minimize the risk of collision between the jettisoned first stage and the Saturn V. These four retrorockets had been omitted from Apollo 15's Saturn V to save weight, but analysis of Apollo 15's flight showed that the S-IC came closer than expected after jettison, and it was feared that if there were only four rockets and one failed, there might be a collision. + +ALSEP and other surface equipment + +As on all lunar landing missions after Apollo 11, an Apollo Lunar Surface Experiments Package (ALSEP) was flown on Apollo 16. This was a suite of nuclear-powered experiments designed to keep functioning after the astronauts who set them up returned to Earth. Apollo 16's ALSEP consisted of a Passive Seismic Experiment (PSE, a seismometer), an Active Seismic Experiment (ASE), a Lunar Heat Flow Experiment (HFE), and a Lunar Surface Magnetometer (LSM). The ALSEP was powered by a SNAP-27 radioisotope thermoelectric generator, developed by the Atomic Energy Commission. + +The PSE added to the network of seismometers left by Apollo 12, 14 and 15. NASA intended to calibrate the Apollo 16 PSE by crashing the LM's ascent stage near it after the astronauts were done with it, an object of known mass and velocity impacting at a known location. However, NASA lost control of the ascent stage after jettison, and this did not occur. The ASE, designed to return data about the Moon's geologic structure, consisted of two groups of explosives: one, a line of "thumpers" were to be deployed attached to three geophones. The thumpers would be exploded during the ALSEP deployment. A second group was four mortars of different sizes, to be set off remotely once the astronauts had returned to Earth. Apollo 14 had also carried an ASE, though its mortars were never set off for fear of affecting other experiments. + +The HFE involved the drilling of two holes into the lunar surface and emplacement of thermometers which would measure how much heat was flowing from the lunar interior. This was the third attempt to emplace a HFE: the first flew on Apollo 13 and never reached the lunar surface, while on Apollo 15, problems with the drill meant the probes did not go as deep as planned. The Apollo 16 attempt would fail after Duke had successfully emplaced the first probe; Young, unable to see his feet in the bulky spacesuit, pulled out and severed the cable after it wrapped around his leg. NASA managers vetoed a repair attempt due to the amount of time it would take. A HFE flew, and was successfully deployed, on Apollo 17. + +The LSM was designed to measure the strength of the Moon's magnetic field, which is only a small fraction of Earth's. Additional data would be returned by the use of the Lunar Portable Magnetometer (LPM), to be carried on the lunar rover and activated at several geology stops. Scientists also hoped to learn from an Apollo 12 sample, to be briefly returned to the Moon on Apollo 16, from which "soft" magnetism had been removed, to see if it had been restored on its journey. Measurements after the mission found that "soft" magnetism had returned to the sample, although at a lower intensity than before. + +A Far Ultraviolet Camera/Spectrograph (UVC) was flown, the first astronomical observations taken from the Moon, seeking data on hydrogen sources in space without the masking effect of the Earth's corona. The instrument was placed in the LM's shadow and pointed at nebulae, other astronomical objects, the Earth itself, and any suspected volcanic vents seen on the lunar surface. The film was returned to Earth. When asked to summarize the results for a general audience, Dr. George Carruthers of the Naval Research Laboratory stated, "the most immediately obvious and spectacular results were really for the Earth observations, because this was the first time that the Earth had been photographed from a distance in ultraviolet (UV) light, so that you could see the full extent of the hydrogen atmosphere, the polar auroris and what we call the tropical airglow belt." + +Four panels mounted on the LM's descent stage comprised the Cosmic Ray Detector, designed to record cosmic ray and solar wind particles. Three of the panels were left uncovered during the voyage to the Moon, with the fourth uncovered by the crew early in the EVA. The panels would be bagged for return to Earth. The free-standing Solar Wind Composition Experiment flew on Apollo 16, as it had on each of the lunar landings, for deployment on the lunar surface and return to Earth. Platinum foil was added to the aluminum of the previous experiments, to minimize contamination. + +Particles and Fields Subsatellite PFS-2 + +The Apollo 16 Particles and Fields Subsatellite (PFS-2) was a small satellite released into lunar orbit from the service module. Its principal objective was to measure charged particles and magnetic fields all around the Moon as the Moon orbited Earth, similar to its sister spacecraft, PFS-1, released eight months earlier by Apollo 15. The two probes were intended to have similar orbits, ranging from above the lunar surface. + +Like the Apollo 15 subsatellite, PFS-2 was expected to have a lifetime of at least a year before its orbit decayed and it crashed onto the lunar surface. The decision to bring Apollo 16 home early after there were difficulties with the main engine meant that the spacecraft did not go to the orbit which had been planned for PFS-2. Instead, it was ejected into a lower-than-planned orbit and crashed into the Moon a month later on May 29, 1972, after circling the Moon 424 times. This brief lifetime was because lunar mascons were near to its orbital ground track and helped pull PFS-2 into the Moon. + +Mission events +Elements of the spacecraft and launch vehicle began arriving at Kennedy Space Center in July 1970, and all had arrived by September 1971. Apollo 16 was originally scheduled to launch on March 17, 1972. One of the bladders for the CM's reaction control system burst during testing. This issue, in combination with concerns that one of the explosive cords that would jettison the LM from the CSM after the astronauts returned from the lunar surface would not work properly, and a problem with Duke's spacesuit, made it desirable to slip the launch to the next launch window. Thus, Apollo 16 was postponed to April 16. The launch vehicle stack, which had been rolled out from the Vehicle Assembly Building on December 13, 1971, was returned thereto on January 27, 1972. It was rolled out again to Launch Complex 39A on February 9. + +The official mission countdown began on Monday, April 10, 1972, at 8:30 am, six days before the launch. At this point the SaturnV rocket's three stages were powered up, and drinking water was pumped into the spacecraft. As the countdown began, the crew of Apollo 16 was participating in final training exercises in anticipation of a launch on April 16. The astronauts underwent their final preflight physical examination on April 11. The only holds in the countdown were the ones pre-planned in the schedule, and the weather was fair as the time for launch approached. + +Launch and outward journey + +The Apollo 16 mission launched from the Kennedy Space Center in Florida at 12:54 pm EST on April 16, 1972. The launch was nominal; the crew experienced vibration similar to that on previous missions. The first and second stages of the SaturnV (the S-IC and S-II) performed nominally; the spacecraft entered orbit around Earth just under 12 minutes after lift-off. + +After reaching orbit, the crew spent time adapting to the zero-gravity environment and preparing the spacecraft for trans-lunar injection (TLI), the burn of the third-stage rocket that would propel them to the Moon. In Earth orbit, the crew faced minor technical issues, including a potential problem with the environmental control system and the S-IVB third stage's attitude control system, but eventually resolved or compensated for them as they prepared to depart towards the Moon. + +After two orbits, the rocket's third stage reignited for just over five minutes, propelling the craft towards the Moon at about . Six minutes after the burn of the S-IVB, the command and service modules (CSM), containing the crew, separated from the rocket and traveled away from it before turning around and retrieving the lunar module from inside the expended rocket stage. The maneuver, performed by Mattingly and known as transposition, docking, and extraction, went smoothly. + +Following transposition and docking, the crew noticed the exterior surface of the lunar module was giving off particles from a spot where the LM's skin appeared torn or shredded; at one point, Duke estimated they were seeing about five to ten particles per second. Young and Duke entered the lunar module through the docking tunnel connecting it with the command module to inspect its systems, at which time they did not spot any major issues. + +Once on course towards the Moon, the crew put the spacecraft into a rotisserie "barbecue" mode in which the craft rotated along its long axis three times per hour to ensure even heat distribution about the spacecraft from the Sun. After further preparing the craft for the voyage, the crew began the first sleep period of the mission just under 15 hours after launch. + +By the time Mission Control issued the wake-up call to the crew for flight day two, the spacecraft was about away from the Earth, traveling at about . As it was not due to arrive in lunar orbit until flight day four, flight days two and three were largely preparatory, consisting of spacecraft maintenance and scientific research. On day two, the crew performed an electrophoresis experiment, also performed on Apollo 14, in which they attempted to demonstrate that electrophoretic separation in their near-weightless environment could be used to produce substances of greater purity than would be possible on Earth. Using two different sizes of polystyrene particles, one size colored red and one blue, separation of the two types via electrophoresis was achieved, though electro-osmosis in the experiment equipment prevented the clear separation of two particle bands. + +The remainder of day two included a two-second mid-course correction burn performed by the CSM's service propulsion system (SPS) engine to tweak the spacecraft's trajectory. Later in the day, the astronauts entered the lunar module for the second time to further inspect the landing craft's systems. The crew reported they had observed additional paint peeling from a portion of the LM's outer aluminum skin. Despite this, the crew discovered that the spacecraft's systems were performing nominally. Following the LM inspection, the crew reviewed checklists and procedures for the following days in anticipation of their arrival and the Lunar Orbit Insertion (LOI) burn. Command Module Pilot Mattingly reported "gimbal lock", meaning that the system to keep track of the craft's attitude was no longer accurate. Mattingly had to realign the guidance system using the Sun and Moon. At the end of day two, Apollo 16 was about away from Earth. + +When the astronauts were awakened for flight day three, the spacecraft was about away from the Earth. The velocity of the craft steadily decreased, as it had not yet reached the lunar sphere of gravitational influence. The early part of day three was largely housekeeping, spacecraft maintenance and exchanging status reports with Mission Control in Houston. The crew performed the Apollo light flash experiment, or ALFMED, to investigate "light flashes" that were seen by Apollo lunar astronauts when the spacecraft was dark, regardless of whether their eyes were open. This was thought to be caused by the penetration of the eye by cosmic ray particles. During the second half of the day, Young and Duke again entered the lunar module to power it up and check its systems, and perform housekeeping tasks in preparation for the lunar landing. The systems were found to be functioning as expected. Following this, the crew donned their space suits and rehearsed procedures that would be used on landing day. Just before the end of flight day three at 59 hours, 19 minutes, 45 seconds after liftoff, while from the Earth and from the Moon, the spacecraft's velocity began increasing as it accelerated towards the Moon after entering the lunar sphere of influence. + +After waking up on flight day four, the crew began preparations for the LOI maneuver that would brake them into orbit. At an altitude of the scientific instrument module (SIM) bay cover was jettisoned. At just over 74 hours into the mission, the spacecraft passed behind the Moon, temporarily losing contact with Mission Control. While over the far side, the SPS burned for 6minutes and 15 seconds, braking the spacecraft into an orbit with a low point (pericynthion) of 58.3 and a high point (apocynthion) of 170.4 nautical miles (108.0 and 315.6 km, respectively). After entering lunar orbit, the crew began preparations for the Descent Orbit Insertion (DOI) maneuver to further modify the spacecraft's orbital trajectory. The maneuver was successful, decreasing the craft's pericynthion to . The remainder of flight day four was spent making observations and preparing for activation of the lunar module, undocking, and landing the following day. + +Lunar surface + +The crew continued preparing for lunar module activation and undocking shortly after waking up to begin flight day five. The boom that extended the mass spectrometer in the SIM bay was stuck, semi-deployed. It was decided that Young and Duke would visually inspect the boom after undocking the LM from the CSM. They entered the LM for activation and checkout of the spacecraft's systems. Despite entering the LM 40 minutes ahead of schedule, they completed preparations only 10 minutes early due to numerous delays in the process. With the preparations finished, they undocked 96 hours, 13 minutes, 31 seconds into the mission. + +For the rest of the two crafts' passes over the near side of the Moon, Mattingly prepared to shift Casper to a higher, near-circular orbit, while Young and Duke prepared Orion for the descent to the lunar surface. At this point, during tests of the CSM's steerable rocket engine in preparation for the burn to modify the craft's orbit, Mattingly detected oscillations in the SPS engine's backup gimbal system. According to mission rules, under such circumstances, Orion was to re-dock with Casper, in case Mission Control decided to abort the landing and use the lunar module's engines for the return trip to Earth. Instead, the two craft kept station, maintaining positions close to each other. After several hours of analysis, mission controllers determined that the malfunction could be worked around, and Young and Duke could proceed with the landing. + +Powered descent to the lunar surface began about six hours behind schedule. Because of the delay, Young and Duke began their descent to the surface at an altitude higher than that of any previous mission, at . After descending to an altitude of about , Young was able to view the landing site in its entirety. Throttle-down of the LM's landing engine occurred on time, and the spacecraft tilted forward to its landing orientation at an altitude of . The LM landed north and west of the planned landing site at 104 hours, 29 minutes, and 35 seconds into the mission, at 2:23:35 UTC on April 21 (8:23:35 pm on April 20 in Houston). The availability of the Lunar Roving Vehicle rendered their distance from the targeted point trivial. + +After landing, Young and Duke began powering down some of the LM's systems to conserve battery power. Upon completing their initial procedures, the pair configured Orion for their three-day stay on the lunar surface, removed their space suits and took initial geological observations of the immediate landing site. They then settled down for their first meal on the surface. After eating, they configured the cabin for sleep. The landing delay caused by the malfunction in the CSM's main engine necessitated significant modifications to the mission schedule. Apollo 16 would spend one less day in lunar orbit after surface exploration had been completed to afford the crew ample margins in the event of further problems. In order to improve Young's and Duke's sleep schedule, the third and final moonwalk of the mission was trimmed from seven hours to five. + +First moonwalk +After waking up on April 21, Young and Duke ate breakfast and began preparations for the first extravehicular activity (EVA), or moonwalk. After the pair donned and pressurized their space suits and depressurized the lunar module cabin, Young climbed out onto the "porch" of the LM, a small platform above the ladder. Duke handed Young a jettison bag full of trash to dispose of on the surface. Young then lowered the equipment transfer bag (ETB), containing equipment for use during the EVA, to the surface. Young descended the ladder and, upon setting foot on the lunar surface, became the ninth human to walk on the Moon. Upon stepping onto the surface, Young expressed his sentiments about being there: "There you are: Mysterious and unknown Descartes. Highland plains. Apollo 16 is gonna change your image. I'm sure glad they got ol' Brer Rabbit, here, back in the briar patch where he belongs." Duke soon descended the ladder and joined Young on the surface, becoming the tenth person to walk on the Moon. Duke was then aged 36; no younger human has ever walked on the lunar surface. Duke expressed his excitement, stating to CAPCOM Anthony England: "Fantastic! Oh, that first foot on the lunar surface is super, Tony!" The pair's first task of the moonwalk was to offload the Lunar Roving Vehicle, the Far Ultraviolet Camera/Spectrograph, and other equipment. This was done without problems. On first driving the lunar rover, Young discovered that the rear steering was not working. He alerted Mission Control to the problem before setting up the television camera, after which Duke erected the United States flag. During lunar surface operations, Commander Young always drove the rover, while Lunar Module Pilot Duke assisted with navigation; this was a division of responsibilities used consistently throughout Apollo's J missions. + +The day's next task was to deploy the ALSEP; while they were parking the lunar rover, on which the TV camera was mounted, to observe the deployment, the rear steering began functioning. After ALSEP deployment, they collected samples in the vicinity. About four hours after the beginning of EVA-1, they mounted the lunar rover and drove to the first geologic stop, Plum Crater, a crater on the rim of Flag Crater, about across. There, at a distance of from the LM, they sampled material in the vicinity, which scientists believed had penetrated through the upper regolith layer to the underlying Cayley Formation. It was there that Duke retrieved, at the request of Mission Control, the largest rock returned by an Apollo mission, a breccia nicknamed Big Muley after mission geology principal investigator William R. Muehlberger. The next stop of the day was Buster Crater, a small crater located north of the larger Spook Crater, about from the LM. There, Duke took pictures of Stone Mountain and South Ray Crater, while Young deployed the LPM. By this point, scientists were beginning to reconsider their pre-mission hypothesis that Descartes had been the setting of ancient volcanic activity, as the two astronauts had yet to find any volcanic material. Following their stop at Buster, Young did a "Grand Prix" demonstration drive of the lunar rover, which Duke filmed with a 16 mm movie camera. This had been attempted on Apollo 15, but the camera had malfunctioned. After completing more tasks at the ALSEP, they returned to the LM to close out the moonwalk. They reentered the LM 7hours, 6minutes, and 56 seconds after the start of the EVA. Once inside, they pressurized the LM cabin, went through a half-hour debriefing with scientists in Mission Control, and configured the cabin for the sleep period. + +Second moonwalk + +Waking up three and a half minutes earlier than planned, they discussed the day's timeline of events with Houston. The second lunar excursion's primary objective was to visit Stone Mountain to climb up the slope of about 20 degrees to reach a cluster of five craters known as "Cinco craters". They drove there in the LRV, traveling from the LM. At above the valley floor, the pair were at the highest elevation above the LM of any Apollo mission. They marveled at the view (including South Ray) from the side of Stone Mountain, which Duke described as "spectacular", then gathered samples in the vicinity. After spending 54 minutes on the slope, they climbed aboard the lunar rover en route to the day's second stop, dubbed Station 5, a crater across. There, they hoped to find Descartes material that had not been contaminated by ejecta from South Ray Crater, a large crater south of the landing site. The samples they collected there, despite still uncertain origin, are according to geologist Wilhelms, "a reasonable bet to be Descartes". + +The next stop, Station 6, was a blocky crater, where the astronauts believed they could sample the Cayley Formation as evidenced by the firmer soil found there. Bypassing station seven to save time, they arrived at Station 8 on the lower flank of Stone Mountain, where they sampled material on a ray from South Ray crater for about an hour. There, they collected black and white breccias and smaller, crystalline rocks rich in plagioclase. At Station 9, an area known as the "Vacant Lot", which was believed to be free of ejecta from South Ray, they spent about 40 minutes gathering samples. Twenty-five minutes after departing the Vacant Lot, they arrived at the final stop of the day, halfway between the ALSEP site and the LM. There, they dug a double core and conducted several penetrometer tests along a line stretching east of the ALSEP. At the request of Young and Duke, the moonwalk was extended by ten minutes. After returning to the LM to wrap up the second lunar excursion, they climbed back inside the landing craft's cabin, sealing and pressurizing the interior after 7hours, 23 minutes, and 26 seconds of EVA time, breaking a record that had been set on Apollo 15. After eating a meal and proceeding with a debriefing on the day's activities with Mission Control, they reconfigured the LM cabin and prepared for the sleep period. + +Third moonwalk + +Flight day seven was their third and final day on the lunar surface, returning to orbit to rejoin Mattingly in the CSM following the day's moonwalk. During the third and final lunar excursion, they were to explore North Ray crater, the largest of any of the craters any Apollo expedition had visited. After exiting Orion, the pair drove to North Ray crater. The drive was smoother than that of the previous day, as the craters were shallower and boulders were less abundant north of the immediate landing site. After passing Palmetto crater, boulders gradually became larger and more abundant as they approached North Ray in the lunar rover. Upon arriving at the rim of North Ray crater, they were away from the LM. After their arrival, the duo took photographs of the wide and deep crater. They visited a large boulder, taller than a four-story building, which became known as 'House Rock'. Samples obtained from this boulder delivered the final blow to the pre-mission volcanic hypothesis, proving it incorrect. House Rock had numerous bullet hole-like marks where micrometeoroids from space had impacted the rock. + +About 1hour and 22 minutes after arriving at the North Ray crater, they departed for Station 13, a large boulder field about from North Ray. On the way, they set a lunar speed record, traveling at an estimated downhill. They arrived at a high boulder, which they called "Shadow Rock". Here, they sampled permanently shadowed soil. During this time, Mattingly was preparing the CSM in anticipation of their return approximately six hours later. After three hours and six minutes, they returned to the LM, where they completed several experiments and unloaded the rover. A short distance from the LM, Duke placed a photograph of his family and an Air Force commemorative medallion on the surface. Young drove the rover to a point about east of the LM, known as the 'VIP site,' so its television camera, controlled remotely by Mission Control, could observe Apollo 16's liftoff from the Moon. They then reentered the LM after a 5-hour and 40-minute final excursion. After pressurizing the LM cabin, the crew began preparing to return to lunar orbit. + +Solo activities + +After Orion was cleared for the landing attempt, Casper maneuvered away, and Mattingly performed a burn that took his spacecraft to an orbit of in preparation for his scientific work. The SM carried a suite of scientific instruments in its SIM bay, similar to those carried on Apollo 15. Mattingly had compiled a busy schedule operating the various SIM bay instruments, one that became even busier once Houston decided to bring Apollo 16 home a day early, as the flight directors sought to make up for lost time. + +His work was hampered by various malfunctions: when the Panoramic Camera was turned on, it appeared to take so much power from one of the CSM's electrical systems, that it initiated the spacecraft Master Alarm. It was immediately shut off, though later analysis indicated that the drain might have been from the spacecraft's heaters, which came on at the same time. Its work was also hampered by the delay in the beginning of Casper'''s orbital scientific work and the early return to Earth, and by a malfunction resulting in the overexposure of many of the photographs. Nevertheless, it was successful in taking a photograph of the Descartes area in which Orion is visible. The Mass Spectrometer boom did not fully retract following its initial extension, as had happened on Apollo 15, though it retracted far enough to allow the SPS engine to be fired safely when Casper maneuvered away from Orion before the LM began its Moon landing attempt. Although the Mass Spectrometer was able to operate effectively, it stuck near its fully deployed position prior to the burn that preceded rendezvous, and had to be jettisoned. Scientists had hoped to supplement the lunar data gained with more on the trans-earth coast, but Apollo 15 data could be used instead. The Mapping Camera also did not function perfectly; later analysis found it to have problems with its glare shield. The changes to the flight plan meant that some areas of the lunar surface that were supposed to be photographed could not be; also, a number of images were overexposed. The Laser Altimeter, designed to accurately measure the spacecraft altitude, slowly lost accuracy due to reduced power, and finally failed just before it was due to be used for the last time. + +Return to Earth + +Eight minutes before the planned departure from the lunar surface, CAPCOM James Irwin notified Young and Duke from Mission Control that they were go for liftoff. Two minutes before launch, they activated the "Master Arm" switch and then the "Abort Stage" button, causing small explosive charges to sever the ascent stage from the descent stage, with cables connecting the two severed by a guillotine-like mechanism. At the pre-programmed moment, there was liftoff and the ascent stage blasted away from the Moon, as the camera aboard the LRV followed the first moments of the flight. Six minutes after liftoff, at a speed of about , Young and Duke reached lunar orbit. Young and Duke successfully rendezvoused and re-docked with Mattingly in the CSM. To minimize the transfer of lunar dust from the LM cabin into the CSM, Young and Duke cleaned the cabin before opening the hatch separating the two spacecraft. After opening the hatch and reuniting with Mattingly, the crew transferred the samples Young and Duke had collected on the surface into the CSM for transfer to Earth. After transfers were completed, the crew would sleep before jettisoning the empty lunar module ascent stage the next day, when it was to be crashed intentionally into the lunar surface in order to calibrate the seismometer Young and Duke had left on the surface. + +The next day, after final checks were completed, the expended LM ascent stage was jettisoned. Likely because of a failure by the crew to activate a certain switch in the LM before sealing it off, it tumbled after separation. NASA could not control it, and it did not execute the rocket burn necessary for the craft's intentional de-orbit. The ascent stage eventually crashed into the lunar surface nearly a year after the mission. The crew's next task, after jettisoning the lunar module ascent stage, was to release a subsatellite into lunar orbit from the CSM's scientific instrument bay. The burn to alter the CSM's orbit to that desired for the subsatellite had been cancelled; as a result, the subsatellite lasted just over a month in orbit, far less than its anticipated one year. Just under five hours after the subsatellite release, on the CSM's 65th orbit around the Moon, its service propulsion system main engine was reignited to propel the craft on a trajectory that would return it to Earth. The SPS engine performed the burn flawlessly despite the malfunction that had delayed their landing several days previously. + +During the return to Earth, Mattingly performed an 83-minute EVA to retrieve film cassettes from the cameras in the SIM bay, with assistance from Duke who remained at the command module's hatch. At approximately from Earth, it was the second "deep space" EVA in history, performed at great distance from any planetary body. , it remains one of only three such EVAs, all performed during Apollo's J-missions under similar circumstances. During the EVA, Mattingly set up a biological experiment, the Microbial Ecology Evaluation Device (MEED), an experiment unique to Apollo 16, to evaluate the response of microbes to the space environment. The crew carried out various housekeeping and maintenance tasks aboard the spacecraft and ate a meal before concluding the day. + +The penultimate day of the flight was largely spent performing experiments, aside from a twenty-minute press conference during the second half of the day. During the press conference, the astronauts answered questions pertaining to several technical and non-technical aspects of the mission prepared and listed by priority at the Manned Spacecraft Center in Houston by journalists covering the flight. In addition to numerous housekeeping tasks, the astronauts prepared the spacecraft for its atmospheric reentry the next day. At the end of the crew's final full day in space, the spacecraft was approximately from Earth and closing at a rate of about . + +When the wake-up call was issued to the crew for their final day in space by CAPCOM England, the CSM was about from Earth, traveling just over . Just over three hours before splashdown in the Pacific Ocean, the crew performed a final course correction burn, using the spacecraft's thrusters to change their velocity by . Approximately ten minutes before reentry into Earth's atmosphere, the cone-shaped command module containing the three crewmembers separated from the service module, which would burn up during reentry. At 265 hours and 37 minutes into the mission, at a velocity of about , Apollo 16 began atmospheric reentry. At its maximum, the temperature of the heat shield was between . After successful parachute deployment and less than 14 minutes after reentry began, the command module splashed down in the Pacific Ocean southeast of the island of Kiritimati 265 hours, 51 minutes, 5seconds after liftoff. The spacecraft and its crew was retrieved by the aircraft carrier . The astronauts were safely aboard the Ticonderoga 37 minutes after splashdown. + + Scientific results and aftermath +Scientific analysis of the rocks brought back to Earth confirmed that the Cayley Formation was not volcanic in nature. There was less certainty regarding the Descartes Formation, as it was not clear which if any of the rocks came from there. There was no evidence that showed that Stone Mountain was volcanic. One reason why Descartes had been selected was that it was visually different from previous Apollo landing sites, but rocks from there proved to be closely related to those from the Fra Mauro Formation, Apollo 14's landing site. Geologists realized that they had been so certain that Cayley was volcanic, they had not been open to dissenting views, and that they had been over-reliant on analogues from Earth, a flawed model because the Moon does not share much of the Earth's geologic history. They concluded that there are few if any volcanic mountains on the Moon. These conclusions were informed by observations from Mattingly, the first CMP to use binoculars in his observations, who had seen that from the perspective of lunar orbit, there was nothing distinctive about the Descartes Formation—it fit right in with the Mare Imbrium structure. Other results gained from Apollo 16 included the discovery of two new auroral belts around Earth. + +After the mission, Young and Duke served as backups for Apollo 17, and Duke retired from NASA in December 1975. Young and Mattingly both flew the Space Shuttle: Young, who served as Chief Astronaut from 1974 to 1987, commanded the first Space Shuttle mission, STS-1 in 1981, as well as STS-9 in 1983, on the latter mission becoming the first person to journey into space six times. He retired from NASA in 2004. Mattingly also twice commanded Shuttle missions, STS-4 (1982) and STS-51-C (1985), before retiring from NASA in 1985. + +Locations of spacecraft and other equipment + +The Ticonderoga delivered the Apollo 16 command module to the North Island Naval Air Station, near San Diego, California, on Friday, May 5, 1972. On Monday, May 8, ground service equipment being used to empty the residual toxic reaction control system fuel in the command module tanks exploded in a Naval Air Station hangar. Forty-six people were sent to the hospital for 24 to 48 hours' observation, most suffering from inhalation of toxic fumes. Most seriously injured was a technician who suffered a fractured kneecap when a cart overturned on him. A hole was blown in the hangar roof 250 feet above; about 40 windows in the hangar were shattered. The command module suffered a three-inch gash in one panel. + +The Apollo 16 command module Casper'' is on display at the U.S. Space & Rocket Center in Huntsville, Alabama, following a transfer of ownership from NASA to the Smithsonian in November 1973. The lunar module ascent stage separated from the CSM on April 24, 1972, but NASA lost control of it. It orbited the Moon for about a year. Its impact site remains unknown, though research published in 2023 suggests an impact date of May 29, 1972 (the same as for the subsattelite) and an impact location of 9.99° N, 104.26° E. +The S-IVB was deliberately crashed into the Moon. However, due to a communication failure before impact the exact location was unknown until January 2016, when it was discovered within Mare Insularum by the Lunar Reconnaissance Orbiter, approximately southwest of Copernicus Crater. + +Duke left two items on the Moon, both of which he photographed while there. One is a plastic-encased photo portrait of his family. The reverse of the photo is signed by Duke's family and bears this message: "This is the family of Astronaut Duke from Planet Earth. Landed on the Moon, April 1972." The other item was a commemorative medal issued by the United States Air Force, which was celebrating its 25th anniversary in 1972. He took two medals, leaving one on the Moon and donating the other to the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Ohio. + +In 2006, shortly after Hurricane Ernesto affected Bath, North Carolina, eleven-year-old Kevin Schanze discovered a piece of metal debris on the ground near his beach home. Schanze and a friend discovered a "stamp" on the flat metal sheet, which upon further inspection turned out to be a faded copy of the Apollo 16 mission insignia. NASA later confirmed the object to be a piece of the first stage of the SaturnV that had launched Apollo 16 into space. In July 2011, after returning the piece of debris at NASA's request, 16-year-old Schanze was given an all-access tour of the Kennedy Space Center and VIP seating for the launch of STS-135, the final mission of the Space Shuttle program. + +See also + List of artificial objects on the Moon + List of spacewalks and moonwalks 1965–1999 + +References + +Bibliography + +External links + + Apollo 16 Traverses, Lunar Photomap 78D2S2(25) + On the Moon with Apollo 16: A guidebook to the Descartes Region by Gene Simmons, NASA, EP-95, 1972 + Apollo 16: "Nothing so hidden..."

Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a biological experiment containing five mice that was carried in the command module. + +Mission planners had two primary goals in deciding on the landing site: to sample lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent volcanic activity. They therefore selected Taurus–Littrow, where formations that had been viewed and pictured from orbit were thought to be volcanic in nature. Since all three crew members had backed up previous Apollo lunar missions, they were familiar with the Apollo spacecraft and had more time for geology training. + +Launched at 12:33 a.m. Eastern Standard Time (EST) on December 7, 1972, following the only launch-pad delay in the course of the whole Apollo program that was caused by a hardware problem, Apollo 17 was a "J-type" mission that included three days on the lunar surface, expanded scientific capability, and the use of the third Lunar Roving Vehicle (LRV). Cernan and Schmitt landed in the Taurus–Littrow valley, completed three moonwalks, took lunar samples and deployed scientific instruments. Orange soil was discovered at Shorty crater; it proved to be volcanic in origin, although from early in the Moon's history. Evans remained in lunar orbit in the command and service module (CSM), taking scientific measurements and photographs. The spacecraft returned to Earth on December 19. + +The mission broke several records for crewed spaceflight, including the longest crewed lunar landing mission (12 days, 14 hours), greatest distance from a spacecraft during an extravehicular activity of any type (7.6 kilometers or 4.7 miles), longest total duration of lunar-surface extravehicular activities (22 hours, 4 minutes), largest lunar-sample return (approximately 115 kg or 254 lb), longest time in lunar orbit (6 days, 4 hours), and greatest number of lunar orbits (75). + +Crew and key Mission Control personnel + +In 1969, NASA announced that the backup crew of Apollo 14 would be Gene Cernan, Ronald Evans, and former X-15 pilot Joe Engle. This put them in line to be the prime crew of Apollo 17, because the Apollo program's crew rotation generally meant that a backup crew would fly as prime crew three missions later. Harrison Schmitt, who was a professional geologist as well as an astronaut, had served on the backup crew of Apollo 15, and thus, because of the rotation, would have been due to fly as lunar module pilot on Apollo 18. + +In September 1970, the plan to launch Apollo 18 was cancelled. The scientific community pressed NASA to assign a geologist, rather than a pilot with non-professional geological training, to an Apollo landing. NASA subsequently assigned Schmitt to Apollo 17 as the lunar module pilot. After that, NASA’s director of flight crew operations, Deke Slayton, was left with the question of who would fill the two other Apollo 17 slots: the rest of the Apollo 15 backup crew (Dick Gordon and Vance Brand), or Cernan and Evans from the Apollo 14 backup crew. Slayton ultimately chose Cernan and Evans. Support at NASA for assigning Cernan was not unanimous. Cernan had crashed a Bell 47G helicopter into the Indian River near Cape Kennedy during a training exercise in January 1971; the accident was later attributed to pilot error, as Cernan had misjudged his altitude before crashing into the water. Jim McDivitt, who was manager of the Apollo Spacecraft Program Office at the time, objected to Cernan's selection because of this accident, but Slayton dismissed the concern. After Cernan was offered command of the mission, he advocated for Engle to fly with him on the mission, but it was made clear to him that Schmitt would be assigned instead, with or without Cernan, so he acquiesced. The prime crew of Apollo 17 was publicly announced on August 13, 1971. + +When assigned to Apollo 17, Cernan was a 38-year-old captain in the United States Navy; he had been selected in the third group of astronauts in 1963, and flown as pilot of Gemini 9A in 1966 and as lunar module pilot of Apollo 10 in 1969 before he served on Apollo 14's backup crew. Evans, 39 years old when assigned to Apollo 17, had been selected as part of the fifth group of astronauts in 1966, and had been a lieutenant commander in the United States Navy. Schmitt, a civilian, was 37 years old when assigned Apollo 17, had a doctorate in geology from Harvard University, and had been selected in the fourth group of astronauts in 1965. Both Evans and Schmitt were making their first spaceflights. + +For the backup crews of Apollo 16 and 17, the final Apollo lunar missions, NASA selected astronauts who had already flown Apollo lunar missions, to take advantage of their experience, and avoid investing time and money in training rookies who would be unlikely to ever fly an Apollo mission. The original backup crew for Apollo 17, announced at the same time as the prime crew, was the crew of Apollo 15: David Scott as commander, Alfred Worden as CMP and James Irwin as LMP, but in May 1972 they were removed from the backup crew because of their roles in the Apollo 15 postal covers incident. They were replaced with the landing crew of Apollo 16: John W. Young as backup crew commander, Charles Duke as LMP, and Apollo 14's CMP, Stuart Roosa. Originally, Apollo 16's CMP, Ken Mattingly, was to be assigned along with his crewmates, but he declined so he could spend more time with his family, his son having just been born, and instead took an assignment to the Space Shuttle program. Roosa had also served as backup CMP for Apollo 16. + +For the Apollo program, in addition to the prime and backup crews that had been used in the Mercury and Gemini programs, NASA assigned a third crew of astronauts, known as the support crew. Their role was to provide any assistance in preparing for the missions that the missions director assigned then. Preparations took place in meetings at facilities across the US and sometimes needed a member of the flight crew to attend them. Because McDivitt was concerned that problems could be created if a prime or backup crew member was unable to attend a meeting, Slayton created the support crews to ensure that someone would be able to attend in their stead. Usually low in seniority, they also assembled the mission's rules, flight plan and checklists, and kept them updated; for Apollo 17, they were Robert F. Overmyer, Robert A. Parker and C. Gordon Fullerton. + +Flight directors were Gerry Griffin, first shift, Gene Kranz and Neil B. Hutchinson, second shift, and Pete Frank and Charles R. Lewis, third shift. According to Kranz, flight directors during the program Apollo had a one-sentence job description, "The flight director may take any actions necessary for crew safety and mission success." Capsule communicators (CAPCOMs) were Fullerton, Parker, Young, Duke, Mattingly, Roosa, Alan Shepard and Joseph P. Allen. + +Mission insignia and call signs +The insignia's most prominent feature is an image of the Greek sun god Apollo backdropped by a rendering of an American eagle, the red bars on the eagle mirroring those on the U.S. flag. Three white stars above the red bars represent the three crewmembers of the mission. The background includes the Moon, the planet Saturn, and a galaxy or nebula. The wing of the eagle partially overlays the Moon, suggesting humanity's established presence there. + +The insignia includes, along with the colors of the U.S. flag (red, white, and blue), the color gold, representative of a "golden age" of spaceflight that was to begin with Apollo 17. The image of Apollo in the mission insignia is a rendering of the Apollo Belvedere sculpture in the Vatican Museums. It looks forward into the future, towards the celestial objects shown in the insignia beyond the Moon. These represent humanity's goals, and the image symbolizes human intelligence, wisdom and ambition. The insignia was designed by artist Robert McCall, based on ideas from the crew. + +In deciding the call signs for the command module (CM) and lunar module (LM), the crew wished to pay tribute to the American public for their support of the Apollo program, and to the mission, and wanted names with a tradition within American history. The CM was given the call sign "America". According to Cernan, this evoked the 19th century sailing ships which were given that name, and was a thank-you to the people of the United States. The crew selected the name "Challenger" for the LM in lieu of an alternative, "Heritage". Cernan stated that the selected name "just seemed to describe more of what the future for America really held, and that was a challenge". After Schmitt stepped onto the Moon from Challenger, he stated, "I think the next generation ought to accept this as a challenge. Let's see them leave footprints like these." + +Planning and training + +Scheduling and landing site selection +Prior to the cancellation of Apollo 18 through 20, Apollo 17 was slated to launch in September 1971 as part of NASA's tentative launch schedule set forth in 1969. The in-flight abort of Apollo 13 and the resulting modifications to the Apollo spacecraft delayed subsequent missions. Following the cancellation of Apollo 20 in early 1970, NASA decided there would be no more than two Apollo missions per year. Part of the reason Apollo 17 was scheduled for December 1972 was to make it fall after the presidential election in November, ensuring that if there was a disaster, it would have no effect on President Richard Nixon's re-election campaign. Nixon had been deeply concerned about the Apollo 13 astronauts, and, fearing another mission in crisis as he ran for re-election, initially decided to omit the funds for Apollo 17 from the budget; he was persuaded to accept a December 1972 date for the mission. + +Like Apollo 15 and 16, Apollo 17 was slated to be a "J-mission", an Apollo mission type that featured lunar surface stays of three days, higher scientific capability, and the usage of the Lunar Roving Vehicle. Since Apollo 17 was to be the final lunar landing of the Apollo program, high-priority landing sites that had not been visited previously were given consideration for potential exploration. Some sites were rejected at earlier stages. For instance, a landing in the crater Copernicus was rejected because Apollo 12 had already obtained samples from that impact, and three other Apollo expeditions had already visited the vicinity of Mare Imbrium, near the rim of which Copernicus is located. The lunar highlands near the crater Tycho were rejected because of the rough terrain that the astronauts would encounter there. A site on the lunar far side in the crater Tsiolkovskiy was rejected due to technical considerations and the operational costs of maintaining communication with Earth during surface operations. Lastly, a landing in a region southwest of Mare Crisium was rejected on the grounds that a Soviet spacecraft could easily access the site and retrieve samples; Luna 20 ultimately did so shortly after the Apollo 17 site selection was made. Schmitt advocated for a landing on the far side of the Moon until told by Director of Flight Operations Christopher C. Kraft that it would not happen as NASA lacked the funds for the necessary communications satellites. + +The three sites that made the final consideration for Apollo 17 were Alphonsus crater, Gassendi crater, and the Taurus–Littrow valley. In making the final landing site decision, mission planners considered the primary objectives for Apollo 17: obtaining old highlands material a substantial distance from Mare Imbrium, sampling material from young volcanic activity (i.e., less than three billion years), and having minimal ground overlap with the orbital ground tracks of Apollo 15 and Apollo 16 to maximize the amount of new data obtained. A significant reason for the selection of Taurus–Littrow was that Apollo 15's CMP, Al Worden, had overflown the site and observed features he described as likely volcanic in nature. + +Gassendi was eliminated because NASA felt that its central peak would be difficult to reach due to the roughness of the local terrain, and, though Alphonsus might be easier operationally than Taurus–Littrow, it was of lesser scientific interest. At Taurus–Littrow, it was believed that the crew would be able to obtain samples of old highland material from the remnants of a landslide event that occurred on the south wall of the valley and the possibility of relatively young, explosive volcanic activity in the area. Although the valley is similar to the landing site of Apollo 15 in that it is on the border of a lunar mare, the advantages of Taurus–Littrow were believed to outweigh the drawbacks. The Apollo Site Selection Board, a committee of NASA personnel and scientists charged with setting out scientific objectives of the Apollo landing missions and selecting landing sites for them, unanimously recommended Taurus–Littrow at its final meeting in February 1972. Upon that recommendation, NASA selected Taurus–Littrow as the landing site for Apollo 17. + +Training + +As with previous lunar landings, the Apollo 17 astronauts undertook an extensive training program that included learning to collect samples on the surface, usage of the spacesuits, navigation in the Lunar Roving Vehicle, field geology training, survival training, splashdown and recovery training, and equipment training. The geology field trips were conducted as much as possible as if the astronauts were on the Moon: they would be provided with aerial images and maps, and briefed on features of the site and a suggested routing. The following day, they would follow the route, and have tasks and observations to be done at each of the stops. + +The geology field trips began with one to Big Bend National Park in Texas in October 1971. The early ones were not specifically tailored to prepare the astronauts for Taurus–Littrow, which was not selected until February 1972, but by June, the astronauts were going on field trips to sites specifically selected to prepare for Apollo 17's landing site. Both Cernan and Schmitt had served on backup crews for Apollo landing missions, and were familiar with many of the procedures. Their trainers, such as Gordon Swann, feared that Cernan would defer to Schmitt as a professional geologist on matters within his field. Cernan also had to adjust for the loss of Engle, with whom he had trained for Apollo 14. In spite of these issues, Cernan and Schmitt worked well together as a team, and Cernan became adept at describing what he was seeing on geology field trips, and working independently of Schmitt when necessary. + +The landing crew aimed for a division of labor so that, when they arrived in a new area, Cernan would perform tasks such as adjusting the antenna on the Lunar Roving Vehicle so as to transmit to Earth while Schmitt gave a report on the geological aspects of the site. The scientists in the geology "backroom" relied on Schmitt's reports to adjust the tasks planned for that site, which would be transmitted to the CapCom and then to Cernan and Schmitt. According to William R. Muehlberger, one of the scientists who trained the astronauts, "In effect [Schmitt] was running the mission from the Moon. But we set it up this way. All of those within the geological world certainly knew it, and I had a sneaking hunch that the top brass knew it too, but this is a practical way out, and they didn't object." + +Also participating in some of the geology field trips were the commander and lunar module pilot of the backup crew. The initial field trips took place before the Apollo 15 astronauts were assigned as the backup crew for Apollo 17 in February 1972. Either one or both of Scott and Irwin of Apollo 15 took part in four field trips, though both were present together for only two of them. After they were removed from the backup crew, the new backup commander and LMP, Young and Duke, took part in the final four field trips. On field trips, the backup crew would follow half an hour after the prime crew, performing identical tasks, and have their own simulated CapCom and Mission Control guiding them. The Apollo 17 astronauts had fourteen field trips—the Apollo 11 crew had only one. + +Evans did not go on the geology field trips, having his own set of trainers—by this time, geology training for the CMP was well-established. He would fly with a NASA geologist/pilot, Dick Laidley, over geologic features, with part of the exercise conducted at , and part at to . The higher altitude was equivalent to what could be seen from the planned lunar orbit of about 60 nmi with binoculars. Evans would be briefed for several hours before each exercise, and given study guides; afterwards, there would be debriefing and evaluation. Evans was trained in lunar geology by Farouk El-Baz late in the training cycle; this continued until close to launch. The CMP was given information regarding the lunar features he would overfly in the CSM and which he was expected to photograph. + +Mission hardware and experiments + +Spacecraft and launch vehicle +The Apollo 17 spacecraft comprised CSM-114 (consisting of Command Module 114 (CM-114) and Service Module 114 (SM-114)); Lunar Module 12 (LM-12); a Spacecraft-Lunar Module Adapter (SLA) numbered SLA-21; and a Launch Escape System (LES). The LES contained a rocket motor that would propel the CM to safety in the event of an aborted mission in the moments after launch, while the SLA housed the LM during the launch and early part of the flight. The LES was jettisoned after the launch vehicle ascended to the point that it was not needed, while the SLA was left atop the S-IVB third stage of the rocket after the CSM and LM separated from it. + +The launch vehicle, SA-512, was one of fifteen Saturn V rockets built, and was the twelfth to fly. With a weight at launch of ( of which was attributable to the spacecraft), Apollo 17's vehicle was slightly lighter than Apollo 16, but heavier than every other crewed Apollo mission. + +Preparation and assembly +The first piece of the launch vehicle to arrive at Kennedy Space Center was the S-II second stage, on October 27, 1970; it was followed by the S-IVB on December 21; the S-IC first stage did not arrive until May 11, 1972, followed by the Instrument Unit on June 7. By then, LM-12 had arrived, the ascent stage on June 16, 1971, and the descent stage the following day; they were not mated until May 18, 1972. CM-114, SM-114 and SLA-21 all arrived on March 24, 1972. The rover reached Kennedy Space Center on June 2, 1972. + +The CM and the service module (SM) were mated on March 28, 1972, and the testing of the spacecraft began that month. The CSM was placed in a vacuum chamber at Kennedy Space Center, and the testing was conducted under those conditions. The LM was also placed in a vacuum chamber; both the prime and the backup crews participated in testing the CSM and LM. During the testing, it was discovered that the LM's rendezvous radar assembly had received too much voltage during earlier tests; it was replaced by the manufacturer, Grumman. The LM's landing radar also malfunctioned intermittently and was also replaced. The front and rear steering motors of the Lunar Roving Vehicle (LRV) also had to be replaced, and it required several modifications. Following the July 1972 removal from the vacuum chamber, the LM's landing gear was installed, and it, the CSM and the SLA were mated to each other. The combined craft was moved into the Vehicle Assembly Building in August for further testing, after which it was mounted on the launch vehicle. After completing testing, including a simulated mission, the LRV was placed in the LM on August 13. + +Erection of the stages of the launch vehicle began on May 15, 1972, in High Bay 3 of the Vehicle Assembly Building, and was completed on June 27. Since the launch vehicles for Skylab 1 and Skylab 2 were being processed in that building at the same time, this marked the first time NASA had three launch vehicles there since the height of the Apollo program in 1969. After the spacecraft was mounted on the launch vehicle on August 24, it was rolled out to Pad 39-A on August 28. Although this was not the final time a Saturn V would fly (another would lift Skylab to orbit), area residents reacted as though it was, and 5,000 of them watched the rollout, during which the prime crew joined the operating crew from Bendix atop the crawler. + +At Pad 39-A, testing continued, and the CSM was electrically mated to the launch vehicle on October 11, 1972. Testing concluded with the countdown demonstration tests, accomplished on November 20 and 21. The countdown to launch began at 7:53 a.m. (12:53 UTC) on December 5, 1972. + +Lunar surface science + +ALSEP +The Apollo Lunar Surface Experiments Package was a suite of nuclear-powered experiments, flown on each landing mission after Apollo 11. This equipment was to be emplaced by the astronauts to continue functioning after the astronauts returned to Earth. For Apollo 17, the ALSEP experiments were a Heat Flow Experiment (HFE), to measure the rate of heat flow from the interior of the Moon, a Lunar Surface Gravimeter (LSG), to measure alterations in the lunar gravity field at the site, a Lunar Atmospheric Composition Experiment (LACE), to investigate what the lunar atmosphere is made up of, a Lunar Seismic Profiling Experiment (LSPE), to detect nearby seismic activity, and a Lunar Ejecta and Meteorites Experiment (LEME), to measure the velocity and energy of dust particles. Of these, only the HFE had been flown before; the others were new. + +The HFE had been flown on the aborted Apollo 13 mission, as well as on Apollo 15 and 16, but placed successfully only on Apollo 15, and unexpected results from that device made scientists anxious for a second successful emplacement. It was successfully deployed on Apollo 17. The lunar gravimeter was intended to detect wavers in gravity, which would provide support for Albert Einstein's general theory of relativity; it ultimately failed to function as intended. The LACE was a surface-deployed module that used a mass spectrometer to analyze the Moon's atmosphere. On previous missions, the Code Cathode Gauge experiment had measured the quantity of atmospheric particles, but the LACE determined which gases were present: principally neon, helium and hydrogen. The LSPE was a seismic-detecting device that used geophones, which would detect explosives to be set off by ground command once the astronauts left the Moon. When operating, it could only send useful data to Earth in high bit rate, meaning that no other ALSEP experiment could send data then, and limiting its operating time. It was turned on to detect the liftoff of the ascent stage, as well as use of the explosives packages, and the ascent stage's impact, and thereafter about once a week, as well as for some 100 hour periods. The LEME had a set of detectors to measure the characteristics of the dust particles it sought. It was hoped that the LEME would detect dust impacting the Moon from elsewhere, such as from comets or interstellar space, but analysis showed that it primarily detected dust moving at slow speeds across the lunar surface. + +All powered ALSEP experiments that remained active were deactivated on September 30, 1977, principally because of budgetary constraints. + +Other lunar-surface science + +Like Apollo 15 and 16, Apollo 17 carried a Lunar Roving Vehicle. In addition to being used by the astronauts for transport from station to station on the mission's three moonwalks, the LRV was used to transport the astronauts' tools, communications equipment, and the lunar samples they gathered. The Apollo 17 LRV was also used to carry some of the scientific instruments, such as the Traverse Gravimeter Experiment (TGE) and Surface Electrical Properties (SEP) experiment. The Apollo 17 LRV traveled a cumulative distance of approximately in a total drive time of about four hours and twenty-six minutes; the greatest distance Cernan and Schmitt traveled from the lunar module was about . + +This was the only mission to carry the TGE, which was built by Draper Laboratory at the Massachusetts Institute of Technology. As gravimeters had been useful in studying the Earth's internal structure, the objective of this experiment was to do the same on the Moon. The gravimeter was used to obtain relative gravity measurements at the landing site in the immediate vicinity of the lunar module, as well as various locations on the mission's traverse routes. Scientists would then use this data to help determine the geological substructure of the landing site and the surrounding vicinity. Measurements were taken while the TGE was mounted on the LRV, and also while the device was placed on the lunar surface. A total of 26 measurements were taken with the TGE during the mission's three moonwalks, with productive results. + +The SEP was also unique to Apollo 17, and included two major components: a transmitting antenna deployed near the lunar module and a receiver mounted on the LRV. At different stops during the mission's traverses, electrical signals traveled from the transmitting device, through the ground, and were received at the LRV. The electrical properties of the lunar regolith could be determined by comparison of the transmitted and received electrical signals. The results of this experiment, which are consistent with lunar rock composition, show that there is almost no water in the area of the Moon in which Apollo 17 landed, to a depth of . + +A long, diameter device, the Lunar Neutron Probe was inserted into one of the holes drilled into the surface to collect core samples. It was designed to measure the quantity of neutrons which penetrated to the detectors it bore along its length. This was intended to measure the rate of the "gardening" process on the lunar surface, whereby the regolith on the surface is slowly mixed or buried due to micrometeorites and other events. Placed during the first EVA, it was retrieved during the third and final EVA. The astronauts brought it with them back to Earth, and the measurements from it were compared with the evidence of neutron flux in the core that had been removed from the hole it had been placed in. Results from the probe and from the cores were instrumental in current theories that the top centimeter of lunar regolith turns over every million years, whereas "gardening" to a depth of one meter takes about a billion years. + +Orbital science + +Biological experiments + +Apollo 17's CM carried a biological cosmic ray experiment (BIOCORE), containing five mice that had been implanted with radiation monitors under their scalps to see whether they suffered damage from cosmic rays. These animals were placed in individual metal tubes inside a sealed container that had its own oxygen supply, and flown on the mission. All five were pocket mice (Perognathus longimembris); this species was chosen because it was well-documented, small, easy to maintain in an isolated state (not requiring drinking water during the mission and with highly concentrated waste), and for its ability to withstand environmental stress. Officially, the mice—four male and one female—were assigned the identification numbers A3326, A3400, A3305, A3356 and A3352. Unofficially, according to Cernan, the Apollo 17 crew dubbed them Fe, Fi, Fo, Fum, and Phooey. + +Four of the five mice survived the flight, though only two of them appeared healthy and active; the cause of death of the fifth mouse was not determined. Of those that survived, the study found lesions in the scalp itself and, in one case, the liver. The scalp lesions and liver lesions appeared to be unrelated to one another; nothing was found that could be attributed to cosmic rays. + +The Biostack experiment was similar to one carried on Apollo 16, and was designed to test the effects of the cosmic rays encountered in space travel on microorganisms that were included, on seeds, and on the eggs of simple animals (brine shrimp and beetles), which were carried in a sealed container. After the mission, the microorganisms and seeds showed little effect, but many of the eggs of all species failed to hatch, or to mature normally; many died or displayed abnormalities. + +Scientific Instrument Module + +The Apollo 17 SM contained the scientific instrument module (SIM) bay. The SIM bay housed three new experiments for use in lunar orbit: a lunar sounder, an infrared scanning radiometer, and a far-ultraviolet spectrometer. A mapping camera, panoramic camera, and a laser altimeter, which had been carried previously, were also included in the SIM bay. + +The lunar sounder was to beam electromagnetic impulses toward the lunar surface, which were designed with the objective of obtaining data to assist in developing a geological model of the interior of the Moon to an approximate depth of . The infrared scanning radiometer was designed with the objective of generating a temperature map of the lunar surface to aid in locating surface features such as rock fields, structural differences in the lunar crust, and volcanic activity. The far-ultraviolet spectrometer was to be used to obtain information on the composition, density, and constituency of the lunar atmosphere. The spectrometer was also designed to detect far-UV radiation emitted by the Sun that had been reflected off the lunar surface. The laser altimeter was designed to measure the altitude of the spacecraft above the lunar surface within approximately , providing altitude information to the panoramic and mapping cameras, which were also in the SIM bay. + +Light-flash phenomenon and other experiments + +Beginning with Apollo 11, crew members observed light flashes that penetrated their closed eyelids. These flashes, described by the astronauts as "streaks" or "specks" of light, were usually observed while the spacecraft was darkened during a sleep period. These flashes, while not observed on the lunar surface, would average about two per minute and were observed by the crew members during the trip out to the Moon, back to Earth, and in lunar orbit. + +The Apollo 17 crew repeated an experiment, also conducted on Apollo 16, with the objective of linking these light flashes with cosmic rays. Evans wore a device over his eyes that recorded the time, strength, and path of high-energy atomic particles that penetrated the device, while the other two wore blindfolds to keep out light. Investigators concluded that the available evidence supports the hypothesis that these flashes occur when charged particles travel through the retina in the eye. + +Apollo 17 carried a sodium-iodide crystal identical to the ones in the gamma-ray spectrometer flown on Apollo 15 and 16. Data from this, once it was examined on Earth, was to be used to help form a baseline, allowing for subtraction of rays from the CM or from cosmic radiation to gain better data from the earlier results. In addition, the S-band transponders in the CSM and LM were pointed at the Moon to gain data on its gravitational field. Results from the Lunar Orbiter probes had revealed that lunar gravity varies slightly due to the presence of mass concentrations, or "mascons". Data from the missions, and from the lunar subsatellites left by Apollo 15 and 16, were used to map such variations in lunar gravity. + +Mission events + +Launch and outbound trip + +Originally planned to launch on December 6, 1972, at 9:53 p.m. EST (2:53 a.m. on December 7 UTC), Apollo 17 was the final crewed SaturnV launch, and the only one to occur at night. The launch was delayed by two hours and forty minutes due to an automatic cutoff in the launch sequencer at the T-30 second mark in the countdown. The cause of the problem was quickly determined to be the launch sequencer's failure to automatically pressurize the liquid oxygen tank in the third stage of the rocket; although launch control noticed this and manually caused the tank to pressurize, the sequencer did not recognize the fix and therefore paused the countdown. The clock was reset and held at the T-22 minute mark while technicians worked around the malfunction in order to continue with the launch. This pause was the only launch delay in the Apollo program caused by a hardware problem. The countdown then resumed, and the liftoff occurred at 12:33 a.m. EST on December 7, 1972. The launch window, which had begun at the originally planned launch time of 9:53 p.m. on December 6, remained open until 1:31 a.m., the latest time at which a launch could have occurred during the December 6–7 window. + +Approximately 500,000 people observed the launch in the immediate vicinity of Kennedy Space Center, despite the early-morning hour. The launch was visible as far away as , and observers in Miami, Florida, reported a "red streak" crossing the northern sky. Among those in attendance at the program's final launch were astronauts Neil Armstrong and Dick Gordon, as well as centenarian Charlie Smith, who alleged he was 130 years old at the time of Apollo 17. + +The ascent resulted in an orbit with an altitude and velocity almost exactly that which had been planned. In the hours following the launch, Apollo 17 orbited the Earth while the crew spent time monitoring and checking the spacecraft to ensure its readiness to depart Earth orbit. At 3:46 a.m. EST, the S-IVB third stage was reignited for the 351-second trans-lunar injection burn to propel the spacecraft towards the Moon. Ground controllers chose a faster trajectory for Apollo 17 than originally planned to allow the vehicle to reach lunar orbit at the planned time, despite the launch delay. The Command and Service Module separated from the S-IVB approximately half an hour following the S-IVB trans-lunar injection burn, after which Evans turned the spacecraft to face the LM, still attached to the S-IVB. The CSM then docked with the LM and extracted it from the S-IVB. Following the LM extraction, Mission Control programmed the S-IVB, no longer needed to propel the spacecraft, to impact the Moon and trip the seismometers left by prior Apollo crews. It struck the Moon just under 87 hours into the mission, triggering the seismometers from Apollo 12, 14, 15 and 16. Approximately nine hours after launch, the crew concluded the mission's first day with a sleep period, until waking up to begin the second day. + +Mission Control and the crew decided to shorten the mission's second day, the first full day in space, in order to adjust the crew's wake-up times for the subsequent days in preparation for an early morning (EST) wake-up time on the day of the lunar landing, then scheduled for early afternoon (EST). This was done since the first day of the mission had been extended because of the launch delay. Following the second rest period, and on the third day of the mission, the crew executed the first mid-course correction, a two-second burn of the CSM's service propulsion engine to adjust the spacecraft's Moon-bound trajectory. Following the burn, the crew opened the hatch separating the CSM and LM in order to check the LM's systems and concluded that they were nominal. So that events would take place at the time indicated in the flight plan, the mission clocks were moved ahead by 2 hours and 40 minutes, the amount of the launch delay, with one hour of it at 45:00:00 into the mission and the remainder at 65:00:00. + +Among their other activities during the outbound trip, the crew photographed the Earth from the spacecraft as it travelled towards the Moon. One of these photographs is now known as The Blue Marble. The crew found that one of the latches holding the CSM and LM together was unlatched. While Schmitt and Cernan were engaged in a second period of LM housekeeping beginning just before sixty hours into the Mission, Evans worked on the balky latch. He was successful, and left it in the position it would need to be in for the CSM-LM docking that would occur upon return from the lunar surface. + +Also during the outward journey, the crew performed a heat flow and convection demonstration, as well as the Apollo light-flash experiment. A few hours before entry into lunar orbit, the SIM door on the SM was jettisoned. At approximately 2:47 p.m. EST on December 10, the service propulsion system engine on the CSM ignited to slow down the CSM/LM stack into lunar orbit. Following orbit insertion and orbital stabilization, the crew began preparations for the landing at Taurus–Littrow. + +Lunar landing + +The day of the landing began with a checkout of the Lunar Module's systems, which revealed no problems preventing continuation of the mission. Cernan, Evans, and Schmitt each donned their spacesuits, and Cernan and Schmitt entered the LM in preparation for separating from the CSM and landing. The LM undocked from the CSM, and the two spacecraft orbited close together for about an hour and a half while the astronauts made visual inspections and conducted their final pre-landing checks. After finally separating from the CSM, the LM Challenger and its crew of two adjusted their orbit, such that its lowest point would pass about above the landing site, and began preparations for the descent to Taurus–Littrow. While Cernan and Schmitt prepared for landing, Evans remained in orbit to take observations, perform experiments and await the return of his crewmates a few days later. + +Soon after completing their preparations for landing and just over two hours following the LM's undocking from the CSM, Cernan and Schmitt began their descent to the Taurus–Littrow valley on the lunar surface with the ignition of the Lunar Module's descent propulsion system (DPS) engine. Approximately ten minutes later, as planned, the LM pitched over, giving Cernan and Schmitt their first look at the landing site during the descent phase and allowing Cernan to guide the spacecraft to a desirable landing target while Schmitt provided data from the flight computer essential for landing. The LM touched down on the lunar surface at 2:55 p.m. EST on December 11, just over twelve minutes after DPS ignition. Challenger landed about east of the planned landing point. Shortly thereafter, the two astronauts began re-configuring the LM for their stay on the surface and began preparations for the first moonwalk of the mission, or EVA-1. + +Lunar surface + +First EVA + +During their approximately 75-hour stay on the lunar surface, Cernan and Schmitt performed three moonwalks (EVAs). The astronauts deployed the LRV, then emplaced the ALSEP and the seismic explosive charges. They drove the rover to nine planned geological-survey stations to collect samples and make observations. Additionally, twelve short sampling stops were made at Schmitt's discretion while riding the rover, during which the astronauts used a handled scoop to get a sample, without dismounting. During lunar-surface operations, Commander Cernan always drove the rover, while Lunar Module Pilot Schmitt was a passenger who assisted with navigation. This division of responsibilities between the two crew positions was used consistently throughout Apollo's J-missions. + +The first lunar excursion began four hours after landing, at 6:54 p.m. EST on December 11. After exiting through the hatch of the LM and descending the ladder to the footpad, Cernan took the first step on the lunar surface of the mission. Just before doing so, Cernan remarked, "I'm on the footpad. And, Houston, as I step off at the surface at Taurus–Littrow, we'd like to dedicate the first step of Apollo 17 to all those who made it possible." After Cernan surveyed the exterior of the LM and commented on the immediate landing site, Schmitt joined Cernan on the surface. The first task was to offload the rover and other equipment from the LM. While working near the rover, Cernan caught his hammer under the right-rear fender extension, accidentally breaking it off. A similar incident occurred on Apollo 16 as John Young maneuvered around the rover. Although this was not a mission-critical issue, the loss of the part caused Cernan and Schmitt to be covered with dust stirred up when the rover was in motion. The crew made a short-lived fix using duct tape at the beginning of the second EVA, attaching a paper map to the damaged fender. Lunar dust stuck to the tape's surface, however, preventing it from adhering properly. Following deployment and testing the maneuverability of the rover, the crew deployed the ALSEP just west of the landing site. The ALSEP deployment took longer than had been planned, with the drilling of core holes presenting some difficulty, meaning the geological portion of the first EVA would need to be shortened, cancelling a planned visit to Emory crater. Instead, following the deployment of the ALSEP, Cernan and Schmitt drove to Steno crater, to the south of the landing site. The objective at Steno was to sample the subsurface material excavated by the impact that formed the crater. The astronauts gathered of samples, took seven gravimeter measurements, and deployed two explosive packages. The explosive packages were later detonated remotely; the resulting explosions detected by geophones placed by the astronauts and also by seismometers left during previous missions. The first EVA ended after seven hours and twelve minutes. and the astronauts remained in the pressurized LM for the next 17 hours. + +Second EVA + +On December 12, awakened by a recording of "Ride of the Valkyries" played from Mission Control, Cernan and Schmitt began their second lunar excursion. The first order of business was to provide the rover's fender a better fix. Overnight, the flight controllers devised a procedure communicated by John Young: taping together four stiff paper maps to form a "replacement fender extension" and then clamping it onto the fender. The astronauts carried out the new fix which did its job without failing until near the end of the third excursion. Cernan and Schmitt then departed for station 2—Nansen Crater, at the foot of the South Massif. When they arrived, their range from the Challenger was 7.6 kilometers (4.7 miles, 25,029 feet). This remains the furthest distance any spacefarers have ever traveled away from the safety of a pressurizable spacecraft while on a planetary body, and also during an EVA of any type. The astronauts were at the extremity of their "walkback limit", a safety constraint meant to ensure that they could walk back to the LM if the rover failed. They began a return trip, traveling northeast in the rover. + +At station 3, Schmitt fell to the ground while working, looking so awkward that Parker jokingly told him that NASA's switchboard had lit up seeking Schmitt's services for Houston's ballet group, and the site of station 3 was in 2019 renamed Ballet Crater. Cernan took a sample at Station 3 that was to be maintained in vacuum until better analytical techniques became available, joking with the CAPCOM, Parker, about placing a note inside. The container remained unopened until 2022. + +Stopping at station 4—Shorty crater—the astronauts discovered orange soil, which proved to be very small beads of volcanic glass formed over 3.5 billion years ago. This discovery caused great excitement among the scientists at Mission Control, who felt that the astronauts may have discovered a volcanic vent. However, post-mission sample analysis revealed that Shorty is not a volcanic vent, but rather an impact crater. Analysis also found the orange soil to be a remnant of a fire fountain. This fire fountain sprayed molten lava high into the lunar sky in the Moon's early days, some 3.5 billion years ago and long before Shorty's creation. The orange volcanic beads were droplets of molten lava from the fountain that solidified and were buried by lava deposits until exposed by the impact that formed Shorty, less than 20 million years ago. + +The final stop before returning to the LM was Camelot crater; throughout the sojourn, the astronauts collected of samples, took another seven gravimeter measurements, and deployed three more explosive packages. Concluding the EVA at seven hours and thirty-seven minutes, Cernan and Schmitt had completed the longest-duration EVA in history to-date, traveling further away from a spacecraft and covering more ground on a planetary body during a single EVA than any other spacefarers. The improvised fender had remained intact throughout, causing the president of the "Auto Body Association of America" to award them honorary lifetime membership. + +Third EVA + +The third moonwalk, the last of the Apollo program, began at 5:25 p.m. EST on December 13. Cernan and Schmitt rode the rover northeast of the landing site, exploring the base of the North Massif and the Sculptured Hills. Stopping at station 6, they examined a house-sized split boulder dubbed Tracy's Rock (or Split Rock), after Cernan's daughter. The ninth and final planned station was conducted at Van Serg crater. The crew collected of lunar samples and took another nine gravimeter measurements. Schmitt had seen a fine-grained rock, unusual for that vicinity, earlier in the mission and had stood it on its edge; before closing out the EVA, he went and got it. Subsequently, designated Sample 70215, it was, at , the largest rock brought back by Apollo 17. A small piece of it is on exhibit at the Smithsonian Institution, one of the few rocks from the Moon that the public may touch. Schmitt also collected a sample, designated as Sample 76535, at geology station 6 near the base of the North Massif; the sample, a troctolite, was later identified as the oldest known "unshocked" lunar rock, meaning it has not been damaged by high-impact geological events. Scientists have therefore used Sample 76535 in thermochronological studies to determine if the Moon formed a metallic core or, as study results suggest, a core dynamo. + +Before concluding the moonwalk, the crew collected a breccia rock, dedicating it to the nations of Earth, 70 of which were represented by students touring the U.S. and present in Mission Control Center in Houston, Texas, at the time. Portions of this sample, known as the Friendship Rock, were subsequently distributed to the nations represented by the students. A plaque located on the LM, commemorating the achievements made during the Apollo program, was then unveiled. Before reentering the LM for the final time, Cernan remarked, + +Cernan then followed Schmitt into the LM; the final lunar excursion had a duration of seven hours and fifteen minutes. Following closing of the LM hatch and repressurization of the LM cabin, Cernan and Schmitt removed their spacesuits and reconfigured the cabin for a final rest period on the lunar surface. As they did following each of the previous two EVAs, Cernan and Schmitt discussed their geological observations from the day's excursion with mission control while preparing to rest. + +Solo activities +While Cernan and Schmitt were on the lunar surface, Evans remained alone in the CSM in lunar orbit and was assigned a number of observational and scientific tasks to perform while awaiting the return of his crewmates. In addition to the operation of the various orbital science equipment contained in the CSM's SIM bay, Evans conducted both visual and photographic observation of surface features from his aerial vantage point. The orbit of the CSM having been modified to an elliptical orbit in preparation for the LM's departure and eventual descent, one of Evans' solo tasks in the CSM was to circularize its orbit such that the CSM would remain at approximately the same distance above the surface throughout its orbit. Evans observed geological features visible to him and used handheld cameras to record certain visual targets. Evans also observed and sketched the solar corona at "sunrise," or the period of time during which the CSM would pass from the darkened portion of the Moon to the illuminated portion when the Moon itself mostly obscured the sun. To photograph portions of the surface that were not illuminated by the sun while Evans passed over them, Evans relied in conjunction on exposure and Earthlight. Evans photographed such features as the craters Eratosthenes and Copernicus, as well as the vicinity of Mare Orientale, using this technique. According to the Apollo 17 Mission Report, Evans was able to capture all scientific photographic targets, as well as some other targets of interest. + +Similarly to the crew of Apollo 16, Evans (as well as Schmitt, while in lunar orbit) reported seeing light "flashes" apparently originating from the lunar surface, known as transient lunar phenomena (TLP); Evans reported seeing these "flashes" in the vicinity of Grimaldi crater and Mare Orientale. The causes of TLP are not well-understood and, though inconclusive as an explanation, both of the sites in which Evans reported seeing TLP are the general locations of outgassing from the Moon's interior. Meteorite impacts are another possible explanation. + +The flight plan kept Evans busy, making him so tired he overslept one morning by an hour, despite the efforts of Mission Control to awaken him. Before the LM departed for the lunar surface, Evans had discovered that he had misplaced his pair of scissors, necessary to open food packets. Cernan and Schmitt lent him one of theirs. The instruments in the SIM bay functioned without significant hindrance during the orbital portion of the mission, though the lunar sounder and the mapping camera encountered minor problems. Evans spent approximately 148 total hours in lunar orbit, including solo time and time spent together with Cernan and Schmitt, which is more time than any other individual has spent orbiting the Moon. + +Evans was also responsible for piloting the CSM during the orbital phase of the mission, maneuvering the spacecraft to alter and maintain its orbital trajectory. In addition to the initial orbital recircularization maneuver shortly after the LM's departure, one of the solo activities Evans performed in the CSM in preparation for the return of his crewmates from the lunar surface was the plane change maneuver. This maneuver was meant to align the CSM's trajectory to the eventual trajectory of the LM to facilitate rendezvous in orbit. Evans fired the SPS engine of the CSM for about 20 seconds in successfully adjusting the CSM's orbital plane. + +Return to Earth + +Cernan and Schmitt successfully lifted off from the lunar surface in the ascent stage of the LM on December14, at 5:54 p.m. EST. The return to lunar orbit took just over seven minutes. The LM, piloted by Cernan, and the CSM, piloted by Evans, maneuvered, and redocked about two hours after liftoff from the surface. Once the docking had taken place, the crew transferred equipment and lunar samples from the LM to the CSM for return to Earth. The crew sealed the hatches between the CSM and the LM ascent stage following completion of the transfer and the LM was jettisoned at 11:51 p.m. EST on December14. The unoccupied ascent stage was then remotely deorbited, crashing it into the Moon with an impact recorded by the seismometers left by Apollo 17 and previous missions. At 6:35 p.m. EST on December16, the CSM's SPS engine was ignited once more to propel the spacecraft away from the Moon on a trajectory back towards Earth. The successful trans-Earth injection SPS burn lasted just over two minutes. + +During the return to Earth, Evans performed a 65-minute EVA to retrieve film cassettes from the service module's SIM bay, with assistance from Schmitt who remained at the command module's hatch. At approximately 160,000 nautical miles (184,000 mi; 296,000 km) from Earth, it was the third "deep space" EVA in history, performed at great distance from any planetary body. As of , it remains one of only three such EVAs, all performed during Apollo's J-missions under similar circumstances. It was the last EVA of the Apollo program. + +During the trip back to Earth, the crew operated the infrared radiometer in the SM, as well as the ultraviolet spectrometer. One midcourse correction was performed, lasting 9 seconds. On December 19, the crew jettisoned the no-longer-needed SM, leaving only the CM for return to Earth. The Apollo 17 spacecraft reentered Earth's atmosphere and splashed down safely in the Pacific Ocean at 2:25 p.m. EST, from the recovery ship, . Cernan, Evans, and Schmitt were then retrieved by a recovery helicopter piloted by Commander Edward E. Dahill, III and were safe aboard the recovery ship 52 minutes after splashdown. As the final Apollo mission concluded successfully, Mission Control in Houston was filled with many former flight controllers and astronauts, who applauded as America returned to Earth. + +Aftermath and spacecraft locations + +Following their mission, the crew undertook both domestic and international tours, visiting 29 states and 11 countries. The tour kicked off at Super Bowl VII, with the crew leading the crowd in the Pledge of Allegiance; the CM America was also displayed during the pregame activities. + +None of the Apollo 17 astronauts flew in space again. Cernan retired from NASA and the Navy in 1976. He died in 2017. Evans retired from the Navy in 1976 and from NASA in 1977, entering the private sector. He died in 1990. Schmitt resigned from NASA in 1975 prior to his successful run for a United States Senate seat from New Mexico in 1976. There, he served one six-year term. + +The Command Module America is currently on display at Space Center Houston at the Lyndon B. Johnson Space Center in Houston, Texas. The ascent stage of Lunar Module Challenger impacted the Moon on December 15, 1972, at 06:50:20.8 UTC (1:50 a.m. EST), at . The descent stage remains on the Moon at the landing site, . In 2023, a study of Apollo-era data from the Lunar Seismic Profiling Experiment showed that the descent stage was causing very slight tremors each lunar morning as components expanded in the heat. + +Eugene Cernan's flown Apollo 17 spacesuit is in the collection of the Smithsonian's National Air and Space Museum (NASM), where it was transferred in 1974, and Harrison Schmitt's is in storage at NASM's Paul E. Garber Facility. Amanda Young of NASM indicated in 2004 that Schmitt's suit is in the best condition of the flown Apollo lunar spacesuits, and therefore is not on public display. Ron Evans' spacesuit was also transferred from NASA in 1974 to the collection of the NASM; it remains in storage. + +Since Apollo 17's return, there have been attempts to photograph the landing site, where the LM's descent stage, LRV and some other mission hardware, remain. In 2009 and again in 2011, the Lunar Reconnaissance Orbiter photographed the landing site from increasingly low orbits. At least one group has indicated an intention to visit the site as well; in 2018, the German space company PTScientists said that it planned to land two lunar rovers nearby. + +See also + + List of Apollo missions + List of astronauts by year of selection + List of human spaceflights + List of human spaceflight programs + List of landings on extraterrestrial bodies + List of crewed spacecraft + List of NASA missions + List of spacewalks and moonwalks 1965–1999 + Moon landing + The Case of the Missing Moon Rocks + Apollo in Real Time + +Notes + +References + +Bibliography + +External links + + Apollo 17 Traverses, 43D1S2(25), Lunar Photomap at Lunar and Planetary Institute + "Apollo 17" – Detailed mission information by David R.

It created the environment for the American Revolutionary War, which lasted from 1775 to 1783, whereby the Thirteen Colonies secured their independence from the British Crown and consequently established the United States as the first sovereign nation state founded on Enlightenment principles of the consent of the governed, constitutionalism and liberal democracy. + +American colonists objected to being taxed by the British Parliament, a body in which they had no direct representation. Prior to the 1760s, British colonial authorities afforded the colonies a relatively high level of autonomy in their internal affairs, which were locally governed by colonial legislatures. During the 1760s, however, the British Parliament passed acts that were intended to bring the American colonies under more direct rule by the British monarchy and intertwine the economies of the American colonies with Britain in ways that benefited the British monarchy and increased the colonies' dependence on it. In 1765, the British Parliament passed the Stamp Act, which imposed taxes on official documents, newspapers and magazines, and most things printed in the colonies, leading to colonial protest and resulting in representatives from several colonies convening the Stamp Act Congress in New York City to plan a response. The British repealed the Stamp Act, alleviating tensions briefly but they flared again in 1767 with Parliament's passage of the Townshend Acts, a group of new taxes and regulations imposed on the thirteen colonies. + +In an effort to quell a mounting rebellion in the colonies, which was particularly severe in the colonial-era Province of Massachusetts Bay, King George III deployed troops to Boston, resulting in the Boston Massacre on March 5, 1770. The British government then repealed most of the Townshend duties in 1770, but it retained its tax on tea in order to symbolically assert Parliament's right to tax the colonies. The thirteen colonies responded assertively, first burning the Gaspee in Rhode Island in 1772 and then launching the Boston Tea Party in Boston Harbor on December 16, 1773, which vastly escalated tensions. The British responded by closing Boston Harbor and enacting a series of punitive laws, which effectively rescinded Massachusetts' governing autonomy. + +In late 1774, in support of Massachusetts, twelve of the thirteen colonies sent delegates to Philadelphia, where they formed the First Continental Congress and began coordinating resistance to Britain's colonial governance. Opponents of Britain were known as "Patriots" or "Whigs", and colonists who retained allegiance to the Crown were known as "Loyalists" or "Tories." In early 1775, the British monarchy declared Massachusetts to be in a state of open defiance and rebellion, and it sent an order to have American patriots disarmed. + +On April 19, 1775, tensions between the British Army and patriot militiamen escalated to open warfare, launching the American Revolutionary War, when British troops were sent to capture a cache of military supplies and were confronted by American patriots at Lexington and Concord. On June 14, 1775, the Second Continental Congress in Philadelphia responded by authorizing formation of the Continental Army and appointed George Washington as its commander-in-chief. In an early victory for the Americans, Washington and the Continental Army engaged British forces in the Siege of Boston, forcing them to withdraw by sea. Each of the thirteen colonies also formed their own Provincial Congress, assuming power from former British-controlled colonial governments. The Provincial Congresses suppressed Loyalists and contributed to the Continental Army. The Patriots unsuccessfully attempted to invade northeastern Quebec in an attempt to rally sympathetic colonists there during the winter of 1775–1776, but were more successful in the southwestern parts of the colony. + +At Independence Hall in Philadelphia, the Second Continental Congress declared King George III a tyrant who trampled the colonists' rights as Englishmen. On July 2, 1776, the Congress passed the Lee Resolution, which declared that the colonies considered themselves "free and independent states". Two days later, on July 4, 1776, the Congress unanimously adopted the Declaration of Independence, which was principally authored by Thomas Jefferson, a member of the Committee of Five charged by Congress with its development. The Declaration of Independence embodied the political philosophies of liberalism and republicanism, rejected monarchy and aristocracy, and famously proclaimed that "all men are created equal". + +In the summer of 1776, in a setback for American patriots, the British captured New York City and its strategic harbor. In September 1777, in anticipation of a coordinated attack by the British Army on the revolutionary capital of Philadelphia, the Continental Congress was forced to depart Philadelphia temporarily for Baltimore, where they continued deliberations. + +In October 1777, the Continental Army experienced a significant victory, capturing British troops at the Battle of Saratoga. Following the victory in the Saratoga campaign, France then entered the war as an ally of the United States and the cause of American independence, which expanded the Revolutionary War into a global conflict. The British Royal Navy blockaded ports and held New York City for the duration of the war, and other cities for brief periods, but failed in their effort to destroy Washington's forces. Britain's priorities shifted southward, attempting to hold the Southern states with the anticipated aid of Loyalists that never materialized. British general Charles Cornwallis captured Continental Army troops at Charleston, South Carolina in early 1780, but he failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory. A combined American and French force captured Cornwallis' army at Yorktown in the fall of 1781, effectively securing an American victory and end to the war. On September 3, 1783, the British signed the Treaty of Paris in which they acknowledged the independence and sovereignty of the thirteen colonies, and led to the formation of the United States, which took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, including southern Canada, while the British retained control of northern Canada, and French ally Spain took back Florida. + +Among the significant results of the American victory were American independence and the end of British mercantilism in America, opening up worldwide trade for the United States, including a resumption of it with Britain. Around 60,000 Loyalists migrated to other British territories in Canada and elsewhere, but the great majority remained in the United States. In 1787, at the Congress of the Confederation in Philadelphia, American delegates authorized, and states then ratified the United States Constitution, which took effect March 4, 1789 and replaced the weaker wartime Articles of Confederation. It provided for a relatively strong national government structured as a federal republic, including an elected executive, a national judiciary, and an elected bicameral Congress representing states in the Senate and the population in the House of Representatives. With its victory in the American Revolution, the United States became the first federal democratic republic in world history founded on the consent of the governed. In 1791, a Bill of Rights was ratified as the first ten amendments, guaranteeing fundamental rights used as justification for the revolution. Subsequent amendments, including the Reconstruction Amendments, the Nineteenth Amendment, and others, extended those rights to ever greater categories of citizens. + +Origin + +1651–1763: Early seeds + +From the start of English colonization of the Americas, the English government pursued a policy of mercantilism, consistent with the economic policies of other European colonial powers of the time. Under this system, they hoped to grow England's economic and political power by restricting imports, promoting exports, regulating commerce, gaining access to new natural resources, and accumulating new precious metals as monetary reserves. Mercantilist policies were a defining feature of several English American colonies from their inception. The original 1606 charter of the Virginia Company regulated trade in what would become the Colony of Virginia. In general, the export of raw materials to foreign lands was banned, imports of foreign goods were discouraged, and cabotage was restricted to English vessels. These regulations were enforced by the Royal Navy. + +Following the Parliamentarian victory in the English Civil War, the first mercantilist legislation was passed. In 1651, the Rump Parliament passed the first of the Navigation Acts, intended to both improve England's trade ties with its colonies and to address Dutch domination of the trans-Atlantic trade at the time. This led to the outbreak of war with the Netherlands the following year. After the Restoration, the 1651 Act was repealed, but the Cavalier Parliament passed a series of even more restrictive Navigation Acts. Colonial reactions to these policies were mixed. The Acts prohibited exports of tobacco and other raw materials to non-English territories, which prevented many planters from receiving higher prices for their goods. Additionally, merchants were restricted from importing certain goods and materials from other nations, harming profits. These factors led to smuggling among colonial merchants, especially following passage of the Molasses Act. On the other hand, certain merchants and local industries benefitted from the restrictions on foreign competition. The restrictions on foreign-built ships also greatly benefitted the colonial shipbuilding industry, particularly of the New England colonies. Some argue that the economic impact was minimal on the colonists, but the political friction which the acts triggered was more serious, as the merchants most directly affected were also the most politically active. + +King Philip's War was fought from 1675 to 1678 between the New England colonies and a handful of indigenous tribes. It was fought without military assistance from England, thereby contributing to the development of a unique American identity separate from that of the British people. The Restoration of King Charles II to the English throne also accelerated this development. New England had strong Puritan heritage and had supported the parliamentarian Commonwealth government that was responsible for the execution of his father, Charles I. Massachusetts did not recognize the legitimacy of Charles II's reign for more than a year after its onset. Charles II thus became determined to bring the New England colonies under a more centralized administration and direct English control in the 1680s. The New England colonists fiercely opposed his efforts, and the Crown nullified their colonial charters in response. Charles' successor James II finalized these efforts in 1686, establishing the consolidated Dominion of New England, which also included the formerly separate colonies of New York and New Jersey. Edmund Andros was appointed royal governor, and tasked with governing the new Dominion under his direct rule. Colonial assemblies and town meetings were restricted, new taxes were levied, and rights were abridged. Dominion rule triggered bitter resentment throughout New England; the enforcement of the unpopular Navigation Acts and the curtailing of local democracy greatly angered the colonists. + +New Englanders were encouraged, however, by a change of government in England which saw King James II effectively abdicate, and a populist uprising in Boston overthrew Dominion rule on April 18, 1689. Colonial governments reasserted their control after the revolt. The new monarchs, William and Mary, granted new charters to the individual New England colonies, and local democratic self-government was restored. Successive Crown governments made no attempts to restore the Dominion. + +Subsequent British governments continued in their efforts to tax certain goods however, passing acts regulating the trade of wool, hats, and molasses. The Molasses Act of 1733 was particularly egregious to the colonists, as a significant part of colonial trade relied on molasses. The taxes severely damaged the New England economy and resulted in a surge of smuggling, bribery, and intimidation of customs officials. Colonial wars fought in America were also a source of considerable tension. For example, New England colonial forces captured the fortress of Louisbourg in Acadia during King George's War in 1745, but the British government then ceded it back to France in 1748 in exchange for Chennai, which the British had lost in 1746. New England colonists resented their losses of lives, as well as the effort and expenditure involved in subduing the fortress, only to have it returned to their erstwhile enemy, who would remain a threat to them after the war. + +Some writers begin their histories of the American Revolution with the British coalition victory in the Seven Years' War in 1763, viewing the French and Indian War as though it were the American theater of the Seven Years' War. Lawrence Henry Gipson writes: + +The Royal Proclamation of 1763 redrew boundaries of the lands west of newly-British Quebec and west of a line running along the crest of the Allegheny Mountains, making them indigenous territory and barred to colonial settlement for two years. The colonists protested, and the boundary line was adjusted in a series of treaties with indigenous tribes. In 1768, the Iroquois agreed to the Treaty of Fort Stanwix, and the Cherokee agreed to the Treaty of Hard Labour followed in 1770 by the Treaty of Lochaber. The treaties opened most of what is present-day Kentucky and West Virginia to colonial settlement. The new map was drawn up at the Treaty of Fort Stanwix, which moved the line much farther to the west, from the green line to the red line on the map at right. + +1764–1766: Taxes imposed and withdrawn + +In 1764 Parliament passed the Sugar Act, decreasing the existing customs duties on sugar and molasses but providing stricter measures of enforcement and collection. That same year, Prime Minister George Grenville proposed direct taxes on the colonies to raise revenue, but he delayed action to see whether the colonies would propose some way to raise the revenue themselves. + +Grenville asserted in 1762 that the whole revenue of the custom houses in America amounted to one or two thousand pounds sterling a year, and that the English exchequer was paying between seven and eight thousand pounds a year to collect. Adam Smith wrote in The Wealth of Nations that Parliament "has never hitherto demanded of [the American colonies] anything which even approached to a just proportion to what was paid by their fellow subjects at home." Benjamin Franklin would later testify in Parliament in 1766 to the contrary, reporting that Americans already contributed heavily to the defense of the Empire. He argued that local colonial governments had raised, outfitted, and paid 25,000 soldiers to fight France in just the French and Indian War alone—as many as Britain itself sent—and spent many millions from American treasuries doing so. + +Parliament passed the Stamp Act in March 1765, which imposed direct taxes on the colonies for the first time. All official documents, newspapers, almanacs, and pamphlets were required to have the stamps—even decks of playing cards. The colonists did not object that the taxes were high; they were actually low. They objected to their lack of representation in the Parliament, which gave them no voice concerning legislation that affected them. The British were, however, reacting to an entirely different issue: at the conclusion of the recent war the Crown had to deal with approximately 1,500 politically well-connected British Army officers. The decision was made to keep them on active duty with full pay, but they—and their commands—also had to be stationed somewhere. Stationing a standing army in Great Britain during peacetime was politically unacceptable, so they determined to station them in America and have the Americans pay them through the new tax. The soldiers had no military mission however; they were not there to defend the colonies because there was no current threat to the colonies. + +Shortly following adoption of the Stamp Act, the Sons of Liberty formed, and began using public demonstrations, boycotts, and threats of violence to ensure that the British tax laws became unenforceable. In Boston, the Sons of Liberty burned the records of the vice admiralty court and looted the home of chief justice Thomas Hutchinson. Several legislatures called for united action, and nine colonies sent delegates to the Stamp Act Congress in New York City in October. Moderates led by John Dickinson drew up a Declaration of Rights and Grievances stating that taxes passed without representation violated their rights as Englishmen, and Congressed emphasized their determination by organizing a boycott on imports of all British merchandise. + +The Parliament at Westminster saw itself as the supreme lawmaking authority throughout the Empire and thus entitled to levy any tax without colonial approval or even consultation. They argued that the colonies were legally British corporations subordinate to the British Parliament, and they pointed to numerous instances where Parliament had made laws in the past that were binding on the colonies. Parliament insisted that the colonists effectively enjoyed a "virtual representation", as most British people did, since only a small minority of the British population elected representatives to Parliament. However, Americans such as James Otis maintained that there was no one in Parliament responsible specifically for any colonial constituency, so they were not "virtually represented" by anyone in Parliament at all. + +The Rockingham government came to power in July 1765, and Parliament debated whether to repeal the stamp tax or to send an army to enforce it. Benjamin Franklin appeared to make the case for repeal, explaining that the colonies had spent heavily in manpower, money, and blood defending the empire in a series of wars against the French and indigenous people, and that further taxes to pay for those wars were unjust and might bring about a rebellion. Parliament agreed and repealed the tax on February 21, 1766, but they insisted in the Declaratory Act of March 1766 that they retained full power to make laws for the colonies "in all cases whatsoever". The repeal nonetheless caused widespread celebrations in the colonies. + +1767–1773: Townshend Acts and the Tea Act + +In 1767, the British Parliament passed the Townshend Acts, which placed duties on several staple goods, including paper, glass, and tea, and established a Board of Customs in Boston to more rigorously execute trade regulations. The new taxes were enacted on the belief that Americans only objected to internal taxes and not to external taxes such as custom duties. However, in his widely read pamphlet, Letters from a Farmer in Pennsylvania, John Dickinson argued against the constitutionality of the acts because their purpose was to raise revenue and not to regulate trade. Colonists responded to the taxes by organizing new boycotts of British goods. These boycotts were less effective, however, as the goods taxed by the Townshend Acts were widely used. + +In February 1768, the Assembly of Massachusetts Bay Colony issued a circular letter to the other colonies urging them to coordinate resistance. The governor dissolved the assembly when it refused to rescind the letter. Meanwhile, a riot broke out in Boston in June 1768 over the seizure of the sloop Liberty, owned by John Hancock, for alleged smuggling. Customs officials were forced to flee, prompting the British to deploy troops to Boston. A Boston town meeting declared that no obedience was due to parliamentary laws and called for the convening of a convention. A convention assembled but only issued a mild protest before dissolving itself. In January 1769, Parliament responded to the unrest by reactivating the Treason Act 1543 which called for subjects outside the realm to face trials for treason in England. The governor of Massachusetts was instructed to collect evidence of said treason, and the threat caused widespread outrage, though it was not carried out. + +On March 5, 1770, a large crowd gathered around a group of British soldiers on a Boston street. The crowd grew threatening, throwing snowballs, rocks, and debris at them. One soldier was clubbed and fell. There was no order to fire, but the soldiers panicked and fired into the crowd. They hit 11 people; three civilians died of wounds at the scene of the shooting, and two died shortly after the incident. The event quickly came to be called the Boston Massacre. The soldiers were tried and acquitted (defended by John Adams), but the widespread descriptions soon began to turn colonial sentiment against the British. This accelerated the downward spiral in the relationship between Britain and the Province of Massachusetts. + +A new ministry under Lord North came to power in 1770, and Parliament withdrew all taxes except the tax on tea, giving up its efforts to raise revenue while maintaining the right to tax. This temporarily resolved the crisis, and the boycott of British goods largely ceased, with only the more radical patriots such as Samuel Adams continuing to agitate. + +In June 1772, American patriots, including John Brown, burned a British warship that had been vigorously enforcing unpopular trade regulations, in what became known as the Gaspee Affair. The affair was investigated for possible treason, but no action was taken. + +In 1772, it became known that the Crown intended to pay fixed salaries to the governors and judges in Massachusetts, which had been paid by local authorities. This would reduce the influence of colonial representatives over their government. In Boston, Samuel Adams set about creating new Committees of Correspondence, which linked Patriots in all 13 colonies and eventually provided the framework for a rebel government. Virginia, the largest colony, set up its Committee of Correspondence in early 1773, on which Patrick Henry and Thomas Jefferson served. + +A total of about 7,000 to 8,000 Patriots served on Committees of Correspondence at the colonial and local levels, comprising most of the leadership in their communities. Loyalists were excluded. The committees became the leaders of the American resistance to British actions, and later largely determined the war effort at the state and local level. When the First Continental Congress decided to boycott British products, the colonial and local Committees took charge, examining merchant records and publishing the names of merchants who attempted to defy the boycott by importing British goods. + +In 1773, private letters were published in which Massachusetts Governor Thomas Hutchinson claimed that the colonists could not enjoy all English liberties, and in which Lieutenant Governor Andrew Oliver called for the direct payment of colonial officials. The letters' contents were used as evidence of a systematic plot against American rights, and discredited Hutchinson in the eyes of the people; the colonial Assembly petitioned for his recall. Benjamin Franklin, postmaster general for the colonies, acknowledged that he leaked the letters, which led to him being berated by British officials and removed from his position. + +Meanwhile, Parliament passed the Tea Act lowering the price of taxed tea exported to the colonies, to help the British East India Company undersell smuggled untaxed Dutch tea. Special consignees were appointed to sell the tea to bypass colonial merchants. The act was opposed by those who resisted the taxes and also by smugglers who stood to lose business. In most instances, the consignees were forced by the Americans to resign and the tea was turned back, but Massachusetts governor Hutchinson refused to allow Boston merchants to give in to pressure. A town meeting in Boston determined that the tea would not be landed, and ignored a demand from the governor to disperse. On December 16, 1773, a group of men, led by Samuel Adams and dressed to evoke the appearance of indigenous people, boarded the ships of the East India Company and dumped £10,000 worth of tea from their holds (approximately £636,000 in 2008) into Boston Harbor. Decades later, this event became known as the Boston Tea Party and remains a significant part of American patriotic lore. + +1774–1775: Intolerable Acts + +The British government responded by passing several measures that came to be known as the Intolerable Acts, further darkening colonial opinion towards England. They consisted of four laws enacted by the British parliament. The first was the Massachusetts Government Act which altered the Massachusetts charter and restricted town meetings. The second act was the Administration of Justice Act which ordered that all British soldiers to be tried were to be arraigned in Britain, not in the colonies. The third Act was the Boston Port Act, which closed the port of Boston until the British had been compensated for the tea lost in the Boston Tea Party. The fourth Act was the Quartering Act of 1774, which allowed royal governors to house British troops in the homes of citizens without requiring permission of the owner. + +In response, Massachusetts patriots issued the Suffolk Resolves and formed an alternative shadow government known as the Provincial Congress, which began training militia outside British-occupied Boston. In September 1774, the First Continental Congress convened, consisting of representatives from each colony, to serve as a vehicle for deliberation and collective action. During secret debates, conservative Joseph Galloway proposed the creation of a colonial Parliament that would be able to approve or disapprove acts of the British Parliament, but his idea was tabled in a vote of 6 to 5 and was subsequently removed from the record. Congress called for a boycott beginning on December 1, 1774, of all British goods; it was enforced by new local committees authorized by the Congress. + +Military hostilities begin + +Massachusetts was declared in a state of rebellion in February 1775 and the British garrison received orders to disarm the rebels and arrest their leaders, leading to the Battles of Lexington and Concord on April 19, 1775. The Patriots laid siege to Boston, expelled royal officials from all the colonies, and took control through the establishment of Provincial Congresses. The Battle of Bunker Hill followed on June 17, 1775. It was a British victory—but at a great cost: about 1,000 British casualties from a garrison of about 6,000, as compared to 500 American casualties from a much larger force. The Second Continental Congress was divided on the best course of action, but eventually produced the Olive Branch Petition, in which they attempted to come to an accord with King George. The king, however, issued a Proclamation of Rebellion which declared that the states were "in rebellion" and the members of Congress were traitors. + +The war that arose was in some ways a classic insurgency. As Benjamin Franklin wrote to Joseph Priestley in October 1775: + +In the winter of 1775, the Americans invaded northeastern Quebec under generals Benedict Arnold and Richard Montgomery, expecting to rally sympathetic colonists there. The attack was a failure; many Americans who weren't killed were either captured or died of smallpox. + +In March 1776, the Continental Army forced the British to evacuate Boston, with George Washington as the commander of the new army. The revolutionaries now fully controlled all thirteen colonies and were ready to declare independence. There still were many Loyalists, but they were no longer in control anywhere by July 1776, and all of the Royal officials had fled. + +Creating new state constitutions + +Following the Battle of Bunker Hill in June 1775, the Patriots had control of Massachusetts outside Boston's city limits, and the Loyalists suddenly found themselves on the defensive with no protection from the British army. In all 13 colonies, Patriots had overthrown their existing governments, closing courts and driving away British officials. They held elected conventions and "legislatures" that existed outside any legal framework; new constitutions were drawn up in each state to supersede royal charters. They proclaimed that they were now states, no longer colonies. + +On January 5, 1776, New Hampshire ratified the first state constitution. In May 1776, Congress voted to suppress all forms of crown authority, to be replaced by locally created authority. New Jersey, South Carolina, and Virginia created their constitutions before July 4. Rhode Island and Connecticut simply took their existing royal charters and deleted all references to the crown. The new states were all committed to republicanism, with no inherited offices. They decided what form of government to create, and also how to select those who would craft the constitutions and how the resulting document would be ratified. On May 26, 1776, John Adams wrote James Sullivan from Philadelphia warning against extending the franchise too far: + +The resulting constitutions in states, including those of Delaware, Maryland, Massachusetts, New York, and Virginia featured: + Property qualifications for voting and even more substantial requirements for elected positions (though New York and Maryland lowered property qualifications) + Bicameral legislatures, with the upper house as a check on the lower + Strong governors with veto power over the legislature and substantial appointment authority + Few or no restraints on individuals holding multiple positions in government + The continuation of state-established religion + +In Pennsylvania, New Jersey, and New Hampshire, the resulting constitutions embodied: + universal manhood suffrage, or minimal property requirements for voting or holding office (New Jersey enfranchised some property-owning widows, a step that it retracted 25 years later) + strong, unicameral legislatures + relatively weak governors without veto powers, and with little appointing authority + prohibition against individuals holding multiple government posts + +The radical provisions of Pennsylvania's constitution, however, lasted only 14 years. In 1790, conservatives gained power in the state legislature, called a new constitutional convention, and rewrote the constitution. The new constitution substantially reduced universal male suffrage, gave the governor veto power and patronage appointment authority, and added an upper house with substantial wealth qualifications to the unicameral legislature. Thomas Paine called it a constitution unworthy of America. + +Independence and Union + +In April 1776, the North Carolina Provincial Congress issued the Halifax Resolves explicitly authorizing its delegates to vote for independence. By June, nine Provincial Congresses were ready for independence; one by one, the last four fell into line: Pennsylvania, Delaware, Maryland, and New York. Richard Henry Lee was instructed by the Virginia legislature to propose independence, and he did so on June 7, 1776. On June 11, a committee was created by the Second Continental Congress to draft a document explaining the justifications for separation from Britain. After securing enough votes for passage, independence was voted for on July 2. + +Gathered at Pennsylvania State House in Philadelphia, 56 of the nation's Founding Fathers, representing America's Thirteen Colonies, unanimously adopted and issued to King George III the Declaration of Independence, which was drafted largely by Thomas Jefferson and presented by the Committee of Five, which had been charged with its development. The Congress struck several provisions of Jefferson's draft, and then adopted it unanimously on July 4. With the issuance of the Declaration of Independence, each colony began operating as independent and autonomous states. The next step was to form a union to facilitate international relations and alliances. + +On November 5, 1777, the Congress approved the Articles of Confederation and Perpetual Union and sent it to each state for ratification. The Congress immediately began operating under the Articles' terms, providing a structure of shared sovereignty during prosecution of the Revolutionary War and facilitating international relations and alliances. The Articles were fully ratified on March 1, 1781. At that point, the Continental Congress was dissolved and a new government of the United States in Congress Assembled took its place the following day, on March 2, 1782, with Samuel Huntington leading the Congress as presiding officer. + +Defending the Revolution + +British return: 1776–1777 + +According to British historian Jeremy Black, the British had significant advantages, including a highly trained army, the world's largest navy, and an efficient system of public finance that could easily fund the war. However, they seriously misunderstood the depth of support for the American Patriot position and ignored the advice of General Gage, misinterpreting the situation as merely a large-scale riot. The British government believed that they could overawe the Americans by sending a large military and naval force, forcing them to be loyal again: + +Washington forced the British out of Boston in the spring of 1776, and neither the British nor the Loyalists controlled any significant areas. The British, however, were amassing forces at their naval base at Halifax, Nova Scotia. They returned in force in July 1776, landing in New York and defeating Washington's Continental Army in August at the Battle of Brooklyn. Following that victory, they requested a meeting with representatives from Congress to negotiate an end to hostilities. + +A delegation including John Adams and Benjamin Franklin met British admiral Richard Howe on Staten Island in New York Harbor on September 11 in what became known as the Staten Island Peace Conference. Howe demanded that the Americans retract the Declaration of Independence, which they refused to do, and negotiations ended. The British then seized New York City and nearly captured Washington's army. They made the city and its strategic harbor their main political and military base of operations, holding it until November 1783. The city became the destination for Loyalist refugees and a focal point of Washington's intelligence network. + +The British also took New Jersey, pushing the Continental Army into Pennsylvania. Washington crossed the Delaware River back into New Jersey in a surprise attack in late December 1776 and defeated the Hessian and British armies at Trenton and Princeton, thereby regaining control of most of New Jersey. The victories gave an important boost to Patriots at a time when morale was flagging, and they have become iconic events of the war. + +In 1777, the British sent Burgoyne's invasion force from Canada south to New York to seal off New England. Their aim was to isolate New England, which the British perceived as the primary source of agitation. Rather than move north to support Burgoyne, the British army in New York City went to Philadelphia in a major case of mis-coordination, capturing it from Washington. The invasion army under Burgoyne was much too slow and became trapped in northern New York state. It surrendered after the Battles of Saratoga in October 1777. From early October 1777 until November 15, a siege distracted British troops at Fort Mifflin, Philadelphia, Pennsylvania, and allowed Washington time to preserve the Continental Army by safely leading his troops to harsh winter quarters at Valley Forge. + +Prisoners + +On August 23, 1775, George III declared Americans to be traitors to the Crown if they took up arms against royal authority. There were thousands of British and Hessian soldiers in American hands following their surrender at the Battles of Saratoga. Lord Germain took a hard line, but the British generals on American soil never held treason trials, and instead treated captured American soldiers as prisoners of war. The dilemma was that tens of thousands of Loyalists were under American control and American retaliation would have been easy. The British built much of their strategy around using these Loyalists. The British maltreated the prisoners whom they held, resulting in more deaths to American prisoners of war than from combat operations. At the end of the war, both sides released their surviving prisoners. + +American alliances after 1778 + +The capture of a British army at Saratoga encouraged the French to formally enter the war in support of Congress, and Benjamin Franklin negotiated a permanent military alliance in early 1778; France thus became the first foreign nation to officially recognize the Declaration of Independence. On February 6, 1778, the United States and France signed the Treaty of Amity and Commerce and the Treaty of Alliance. William Pitt spoke out in Parliament urging Britain to make peace in America and to unite with America against France, while British politicians who had sympathized with colonial grievances now turned against the Americans for allying with Britain's rival and enemy. + +The Spanish and the Dutch became allies of the French in 1779 and 1780 respectively, forcing the British to fight a global war without major allies, and requiring it to slip through a combined blockade of the Atlantic. Britain began to view the American war for independence as merely one front in a wider war, and the British chose to withdraw troops from America to reinforce the British colonies in the Caribbean, which were under threat of Spanish or French invasion. British commander Sir Henry Clinton evacuated Philadelphia and returned to New York City. General Washington intercepted him in the Battle of Monmouth Court House, the last major battle fought in the north. After an inconclusive engagement, the British retreated to New York City. The northern war subsequently became a stalemate, as the focus of attention shifted to the smaller southern theater. + +The British move South: 1778–1783 + +The British strategy in America now concentrated on a campaign in the southern states. With fewer regular troops at their disposal, the British commanders saw the "southern strategy" as a more viable plan, as they perceived the south as strongly Loyalist with a large population of recent immigrants and large numbers of slaves who might be tempted to run away from their masters to join the British and gain their freedom. + +Beginning in late December 1778, the British captured Savannah and controlled the Georgia coastline. In 1780, they launched a fresh invasion and took Charleston, as well. A significant victory at the Battle of Camden meant that royal forces soon controlled most of Georgia and South Carolina. The British set up a network of forts inland, hoping that the Loyalists would rally to the flag. Not enough Loyalists turned out, however, and the British had to fight their way north into North Carolina and Virginia with a severely weakened army. Behind them, much of the territory that they had already captured dissolved into a chaotic guerrilla war, fought predominantly between bands of Loyalists and American militia, and which negated many of the gains that the British had previously made. + +Surrender at Yorktown (1781) + +The British army under Cornwallis marched to Yorktown, Virginia, where they expected to be rescued by a British fleet. The fleet did arrive, but so did a larger French fleet. The French were victorious in the Battle of the Chesapeake, and the British fleet returned to New York for reinforcements, leaving Cornwallis trapped. In October 1781, the British surrendered their second invading army of the war under a siege by the combined French and Continental armies commanded by Washington. + +The end of the war +Washington did not know if or when the British might reopen hostilities after Yorktown. They still had 26,000 troops occupying New York City, Charleston, and Savannah, together with a powerful fleet. The French army and navy departed, so the Americans were on their own in 1782–83. The American treasury was empty, and the unpaid soldiers were growing restive, almost to the point of mutiny or possible coup d'etat. Washington dispelled the unrest among officers of the Newburgh Conspiracy in 1783, and Congress subsequently created the promise of a five years bonus for all officers. + +Historians continue to debate whether the odds were long or short for American victory. John E. Ferling says that the odds were so long that the American victory was "almost a miracle". On the other hand, Joseph Ellis says that the odds favored the Americans, and asks whether there ever was any realistic chance for the British to win. He argues that this opportunity came only once, in the summer of 1776, and the British failed that test. Admiral Howe and his brother General Howe "missed several opportunities to destroy the Continental Army .... Chance, luck, and even the vagaries of the weather played crucial roles." Ellis's point is that the strategic and tactical decisions of the Howes were fatally flawed because they underestimated the challenges posed by the Patriots. Ellis concludes that, once the Howe brothers failed, the opportunity "would never come again" for a British victory. + +Support for the conflict had never been strong in Britain, where many sympathized with the Americans, but now it reached a new low. King George wanted to fight on, but his supporters lost control of Parliament and they launched no further offensives in America on the eastern seaboard. However, the British continued formal and informal assistance to Indian tribes making war on US citizens over the next three decades, which contributed to a "Second American Revolution" in the War of 1812. In that war against Britain, the US permanently established its territory and its citizenship independent of the British Empire. + +Paris peace treaty + +During negotiations in Paris, the American delegation discovered that France supported American independence but no territorial gains, hoping to confine the new nation to the area east of the Appalachian Mountains. The Americans opened direct secret negotiations with London, cutting out the French. British Prime Minister Lord Shelburne was in charge of the British negotiations, and he saw a chance to make the United States a valuable economic partner. The US obtained all the land east of the Mississippi River, including southern Canada, but Spain took control of Florida from the British. It gained fishing rights off Canadian coasts, and agreed to allow British merchants and Loyalists to recover their property. Prime Minister Shelburne foresaw highly profitable two-way trade between Britain and the rapidly growing United States, which did come to pass. The blockade was lifted and all British interference had been driven out, and American merchants were free to trade with any nation anywhere in the world. + +The British largely abandoned their indigenous allies, who were not a party to this treaty and did not recognize it until they were defeated militarily by the United States. However, the British did sell them munitions and maintain forts in American territory until the Jay Treaty of 1795. + +Losing the war and the Thirteen Colonies was a shock to Britain. The war revealed the limitations of Britain's fiscal-military state when they discovered that they suddenly faced powerful enemies with no allies, and they were dependent on extended and vulnerable transatlantic lines of communication. The defeat heightened dissension and escalated political antagonism to the King's ministers. The King went so far as to draft letters of abdication, although they were never delivered. Inside Parliament, the primary concern changed from fears of an over-mighty monarch to the issues of representation, parliamentary reform, and government retrenchment. Reformers sought to destroy what they saw as widespread institutional corruption, and the result was a crisis from 1776 to 1783. The crisis ended after 1784 confidence in the British constitution was restored during the administration of Prime Minister William Pitt. + +Finance + +Britain's war against the Americans, the French, and the Spanish cost about £100 million, and the Treasury borrowed 40 percent of the money that it needed. Meanwhile in Paris, heavy spending and a weak tax base brought France to the verge of bankruptcy and revolution. In London the British had relatively little difficulty financing their war, keeping their suppliers and soldiers paid, and hiring tens of thousands of German soldiers. Britain had a sophisticated financial system based on the wealth of thousands of landowners who supported the government, together with banks and financiers in London. The British tax system collected about 12 percent of the GDP in taxes during the 1770s. + +In sharp contrast, Congress and the American states had no end of difficulty financing the war. In 1775, there was at most 12 million dollars in gold in the colonies, not nearly enough to cover current transactions, let alone finance a major war. The British made the situation much worse by imposing a tight blockade on every American port, which cut off almost all imports and exports. One partial solution was to rely on volunteer support from militiamen and donations from patriotic citizens. Another was to delay actual payments, pay soldiers and suppliers in depreciated currency, and promise that it would be made good after the war. Indeed, the soldiers and officers were given land grants in 1783 to cover the wages that they had earned but had not been paid during the war. The national government did not have a strong leader in financial matters until 1781, when Robert Morris was named Superintendent of Finance of the United States. Morris used a French loan in 1782 to set up the private Bank of North America to finance the war. He reduced the civil list, saved money by using competitive bidding for contracts, tightened accounting procedures, and demanded the national government's full share of money and supplies from the individual states. + +Congress used four main methods to cover the cost of the war, which cost about 66 million dollars in specie (gold and silver). Congress made issues of paper money, known colloquially as "Continental Dollars", in 1775–1780 and in 1780–1781. The first issue amounted to 242 million dollars. This paper money would supposedly be redeemed for state taxes, but the holders were eventually paid off in 1791 at the rate of one cent on the dollar. By 1780, the paper money was so devalued that the phrase "not worth a Continental" became synonymous with worthlessness. The skyrocketing inflation was a hardship on the few people who had fixed incomes, but 90 percent of the people were farmers and were not directly affected by it. Debtors benefited by paying off their debts with depreciated paper. The greatest burden was borne by the soldiers of the Continental Army whose wages were usually paid late and declined in value every month, weakening their morale and adding to the hardships of their families. + +Beginning in 1777, Congress repeatedly asked the states to provide money, but the states had no system of taxation and were of little help. By 1780, Congress was making requisitions for specific supplies of corn, beef, pork, and other necessities, an inefficient system which barely kept the army alive. Starting in 1776, the Congress sought to raise money by loans from wealthy individuals, promising to redeem the bonds after the war. The bonds were redeemed in 1791 at face value, but the scheme raised little money because Americans had little specie, and many of the rich merchants were supporters of the Crown. The French secretly supplied the Americans with money, gunpowder, and munitions to weaken Great Britain; the subsidies continued when France entered the war in 1778, and the French government and Paris bankers lent large sums to the American war effort. The Americans struggled to pay off the loans; they ceased making interest payments to France in 1785 and defaulted on installments due in 1787. In 1790, however, they resumed regular payments on their debts to the French, and settled their accounts with the French government in 1795 when James Swan, an American banker, assumed responsibility for the balance of the debt in exchange for the right to refinance it at a profit. + +Concluding the Revolution + +Creating a "more perfect union" and guaranteeing rights +The war ended in 1783 and was followed by a period of prosperity. The national government was still operating under the Articles of Confederation and settled the issue of the western territories, which the states ceded to Congress. American settlers moved rapidly into those areas, with Vermont, Kentucky, and Tennessee becoming states in the 1790s. + +However, the national government had no money either to pay the war debts owed to European nations and the private banks, or to pay Americans who had been given millions of dollars of promissory notes for supplies during the war. Nationalists led by Washington, Alexander Hamilton, and other veterans feared that the new nation was too fragile to withstand an international war, or even the repetition of internal revolts such as the Shays' Rebellion of 1786 in Massachusetts. They convinced Congress to call the Philadelphia Convention in 1787. The Convention adopted a new Constitution which provided for a republic with a much stronger national government in a federal framework, including an effective executive in a check-and-balance system with the judiciary and legislature. The Constitution was ratified in 1788, after a fierce debate in the states over the proposed new government. The new administration under President George Washington took office in New York in March 1789. James Madison spearheaded Congressional legislation proposing amendments to the Constitution as assurances to those cautious about federal power, guaranteeing many of the inalienable rights that formed a foundation for the revolution. Rhode Island was the final state to ratify the Constitution in 1790, the first ten amendments were ratified in 1791 and became known as the United States Bill of Rights. + +National debt + +The national debt fell into three categories after the American Revolution. The first was the $12 million owed to foreigners, mostly money borrowed from France. There was general agreement to pay the foreign debts at full value. The national government owed $40 million and state governments owed $25 million to Americans who had sold food, horses, and supplies to the Patriot forces. There were also other debts which consisted of promissory notes issued during the war to soldiers, merchants, and farmers who accepted these payments on the premise that the new Constitution would create a government that would pay these debts eventually. + +The war expenses of the individual states added up to $114 million, compared to $37 million by the central government. In 1790, Congress combined the remaining state debts with the foreign and domestic debts into one national debt totaling $80 million at the recommendation of first Secretary of the Treasury Alexander Hamilton. Everyone received face value for wartime certificates, so that the national honor would be sustained and the national credit established. + +Ideology and factions +The population of the Thirteen States was not homogeneous in political views and attitudes. Loyalties and allegiances varied widely within regions and communities and even within families, and sometimes shifted during the Revolution. + +Ideology behind the Revolution + +The American Enlightenment was a critical precursor of the American Revolution. Chief among the ideas of the American Enlightenment were the concepts of natural law, natural rights, consent of the governed, individualism, property rights, self-ownership, self-determination, liberalism, republicanism, and defense against corruption. A growing number of American colonists embraced these views and fostered an intellectual environment which led to a new sense of political and social identity. + +Liberalism + +John Locke (1632–1704) is often referred to as "the philosopher of the American Revolution" due to his work in the Social Contract and Natural Rights theories that underpinned the Revolution's political ideology. Locke's Two Treatises of Government published in 1689 was especially influential. He argued that all humans were created equally free, and governments therefore needed the "consent of the governed". In late eighteenth-century America, belief was still widespread in "equality by creation" and "rights by creation". Locke's ideas on liberty influenced the political thinking of English writers such as John Trenchard, Thomas Gordon, and Benjamin Hoadly, whose political ideas in turn also had a strong influence on the American Patriots. + +The theory of the social contract influenced the belief among many of the Founders that the right of the people to overthrow their leaders, should those leaders betray the historic rights of Englishmen, was one of the "natural rights" of man. The Americans heavily relied on Montesquieu's analysis of the wisdom of the "balanced" British Constitution (mixed government) in writing the state and national constitutions. + +Republicanism + +The most basic features of republicanism anywhere are a representational government in which citizens elect leaders from among themselves for a predefined term, as opposed to a permanent ruling class or aristocracy, and laws are passed by these leaders for the benefit of the entire republic. In addition, unlike a direct or "pure" democracy in which the majority vote rules, a republic codifies in a charter or constitution a certain set of basic civil rights that is guaranteed to every citizen and cannot be overridden by majority rule. + +The American interpretation of "republicanism" was inspired by the Whig party in Great Britain which openly criticized the corruption within the British government. Americans were increasingly embracing republican values, seeing Britain as corrupt and hostile to American interests. The colonists associated political corruption with ostentatious luxury and inherited aristocracy, which they condemned. + +The Founding Fathers were strong advocates of republican values, particularly Samuel Adams, Patrick Henry, John Adams, Benjamin Franklin, Thomas Jefferson, Thomas Paine, George Washington, James Madison, and Alexander Hamilton, which required men to put civic duty ahead of their personal desires. Men were honor bound by civic obligation to be prepared and willing to fight for the rights and liberties of their countrymen. John Adams wrote to Mercy Otis Warren in 1776, agreeing with some classical Greek and Roman thinkers: "Public Virtue cannot exist without private, and public Virtue is the only Foundation of Republics." He continued: + +"Republican motherhood" became the ideal for American women, exemplified by Abigail Adams and Mercy Otis Warren; the first duty of the republican woman was to instill republican values in her children and to avoid luxury and ostentation. + +Protestant Dissenters and the Great Awakening + +Protestant churches that had separated from the Church of England, called "dissenters", were the "school of democracy", in the words of historian Patricia Bonomi. Before the Revolution, the Southern Colonies and three of the New England Colonies had official established churches: Congregational in Massachusetts Bay, Connecticut, and New Hampshire, and the Church of England in Maryland, Virginia, North-Carolina, South Carolina, and Georgia. The New York, New Jersey, Pennsylvania, Delaware, and the Colony of Rhode Island and Providence Plantations had no officially established churches. Church membership statistics from the period are unreliable and scarce, but what little data exists indicates that the Church of England was not in the majority, not even in the colonies where the it was the established church, and they probably did not comprise even 30 percent of the population in most localities (with the possible exception of Virginia). + +John Witherspoon, president of the College of New Jersey (now Princeton University), who was considered a "new light" Presbyterian, wrote widely circulated sermons linking the American Revolution to the teachings of the Bible. Throughout the colonies, dissenting Protestant ministers from the Congregational, Baptist, and Presbyterian churches preached Revolutionary themes in their sermons while most Church of England clergymen preached loyalty to the king, the titular head of the English state church. Religious motivation for fighting tyranny transcended socioeconomic lines to encompass rich and poor, men and women, frontierspeople and townspeople, farmers and merchants. The Declaration of Independence also referred to the "Laws of Nature and of Nature's God" as justification for the Americans' separation from the British monarchy. Most eighteenth-century Americans believed that the entire universe ("nature") was God's creation and he was "Nature's God". Everything was part of the "universal order of things" which began with God and was directed by his providence. Accordingly, the signers of the Declaration professed their "firm reliance on the Protection of divine Providence", and they appealed to "the Supreme Judge for the rectitude of our intentions". George Washington was firmly convinced that he was an instrument of providence, to the benefit of the American people and of all humanity. + +Historian Bernard Bailyn argues that the evangelicalism of the era challenged traditional notions of natural hierarchy by preaching that the Bible teaches that all men are equal, so that the true value of a man lies in his moral behavior, not in his class. Kidd argues that religious disestablishment, belief in God as the source of human rights, and shared convictions about sin, virtue, and divine providence worked together to unite rationalists and evangelicals and thus encouraged a large proportion of Americans to fight for independence from the Empire. Bailyn, on the other hand, denies that religion played such a critical role. Alan Heimert argues that New Light anti-authoritarianism was essential to furthering democracy in colonial American society, and set the stage for a confrontation with British monarchical and aristocratic rule. + +Class and psychology of the factions + +John Adams concluded in 1818: + +In the mid-20th century, historian Leonard Woods Labaree identified eight characteristics of the Loyalists that made them essentially conservative, opposite to the characteristics of the Patriots. Loyalists tended to feel that resistance to the Crown was morally wrong, while the Patriots thought that morality was on their side. Loyalists were alienated when the Patriots resorted to violence, such as burning houses and tarring and feathering. Loyalists wanted to take a centrist position and resisted the Patriots' demand to declare their opposition to the Crown. Many Loyalists had maintained strong and long-standing relations with Britain, especially merchants in port cities such as New York and Boston. Many Loyalists felt that independence was bound to come eventually, but they were fearful that revolution might lead to anarchy, tyranny, or mob rule. In contrast, the prevailing attitude among Patriots was a desire to seize the initiative. Labaree also wrote that Loyalists were pessimists who lacked the confidence in the future displayed by the Patriots. + +Historians in the early 20th century such as J. Franklin Jameson examined the class composition of the Patriot cause, looking for evidence of a class war inside the revolution. More recent historians have largely abandoned that interpretation, emphasizing instead the high level of ideological unity. Both Loyalists and Patriots were a "mixed lot", but ideological demands always came first. The Patriots viewed independence as a means to gain freedom from British oppression and to reassert their basic rights. Most yeomen farmers, craftsmen, and small merchants joined the Patriot cause to demand more political equality. They were especially successful in Pennsylvania but less so in New England, where John Adams attacked Thomas Paine's Common Sense for the "absurd democratical notions" that it proposed. + +King George III + +The revolution became a personal issue for the king, fueled by his growing belief that British leniency would be taken as weakness by the Americans. He also sincerely believed that he was defending Britain's constitution against usurpers, rather than opposing patriots fighting for their natural rights. + +Although Prime Minister Lord North was not an ideal war leader, George III managed to give Parliament a sense of purpose to fight, and Lord North was able to keep his cabinet together. Lord North's cabinet ministers, the Earl of Sandwich, First Lord of the Admiralty, and Lord George Germain, Secretary of State for the Colonies, however, proved to lack leadership skills suited for their positions, which in turn, aided the American revolutionaries. + +King George III is often accused of obstinately trying to keep Great Britain at war with the revolutionaries in America, despite the opinions of his own ministers. In the words of the British historian George Otto Trevelyan, the King was determined "never to acknowledge the independence of the Americans, and to punish their contumacy by the indefinite prolongation of a war which promised to be eternal." The king wanted to "keep the rebels harassed, anxious, and poor, until the day when, by a natural and inevitable process, discontent and disappointment were converted into penitence and remorse". Later historians defend George by saying in the context of the times no king would willingly surrender such a large territory, and his conduct was far less ruthless than contemporary monarchs in Europe. After the surrender of a British army at Saratoga, both Parliament and the British people were largely in favor of the war; recruitment ran at high levels and although political opponents were vocal, they remained a small minority. + +With the setbacks in America, Lord North asked to transfer power to Lord Chatham, whom he thought more capable, but George refused to do so; he suggested instead that Chatham serve as a subordinate minister in North's administration, but Chatham refused. He died later in the same year. Lord North was allied to the "King's Friends" in Parliament and believed George III had the right to exercise powers. In early 1778, Britain's chief rival France signed a treaty of alliance with the United States, and the confrontation soon escalated from a "rebellion" to something that has been characterized as "world war". The French fleet was able to outrun the British naval blockade of the Mediterranean and sailed to North America. The conflict now affected North America, Europe and India. The United States and France were joined by Spain in 1779 and the Dutch Republic, while Britain had no major allies of its own, except for the Loyalist minority in America and German auxiliaries (i.e. Hessians). Lord Gower and Lord Weymouth both resigned from the government. Lord North again requested that he also be allowed to resign, but he stayed in office at George III's insistence. Opposition to the costly war was increasing, and in June 1780 contributed to disturbances in London known as the Gordon riots. + +As late as the Siege of Charleston in 1780, Loyalists could still believe in their eventual victory, as British troops inflicted defeats on the Continental forces at the Battle of Camden and the Battle of Guilford Court House. In late 1781, the news of Cornwallis's surrender at the siege of Yorktown reached London; Lord North's parliamentary support ebbed away and he resigned the following year. The king drafted an abdication notice, which was never delivered, finally accepted the defeat in North America, and authorized peace negotiations. The Treaties of Paris, by which Britain recognized the independence of the United States and returned Florida to Spain, were signed in 1782 and 1783 respectively. In early 1783, George III privately conceded "America is lost!" He reflected that the Northern colonies had developed into Britain's "successful rivals" in commercial trade and fishing. + +When John Adams was appointed American Minister to London in 1785, George had become resigned to the new relationship between his country and the former colonies. He told Adams, "I was the last to consent to the separation; but the separation having been made and having become inevitable, I have always said, as I say now, that I would be the first to meet the friendship of the United States as an independent power." + +Patriots + +Those who fought for independence were called "Revolutionaries" "Continentals", "Rebels", "Patriots", "Whigs", "Congress-men", or "Americans" during and after the war. They included a full range of social and economic classes but were unanimous regarding the need to defend the rights of Americans and uphold the principles of republicanism in rejecting monarchy and aristocracy, while emphasizing civic virtue by citizens. The signers of the Declaration of Independence were mostly—with definite exceptions—well-educated, of British stock, and of the Protestant faith. Newspapers were strongholds of patriotism (although there were a few Loyalist papers) and printed many pamphlets, announcements, patriotic letters, and pronouncements. + +According to historian Robert Calhoon, 40 to 45 percent of the white population in the Thirteen Colonies supported the Patriots' cause, 15 to 20 percent supported the Loyalists, and the remainder were neutral or kept a low profile. Mark Lender analyzes why ordinary people became insurgents against the British, even if they were unfamiliar with the ideological reasons behind the war. He concludes that such people held a sense of rights which the British were violating, rights that stressed local autonomy, fair dealing, and government by consent. They were highly sensitive to the issue of tyranny, which they saw manifested in the British response to the Boston Tea Party. The arrival in Boston of the British Army heightened their sense of violated rights, leading to rage and demands for revenge. They had faith that God was on their side. + +Thomas Paine published his pamphlet Common Sense in January 1776, after the Revolution had started. It was widely distributed and often read aloud in taverns, contributing significantly to concurrently spreading the ideas of republicanism and liberalism, bolstering enthusiasm for separation from Great Britain and encouraging recruitment for the Continental Army. Paine presented the Revolution as the solution for Americans alarmed by the threat of tyranny. + +Loyalists + +The consensus of scholars is that about 15 to 20 percent of the white population remained loyal to the British Crown. Those who actively supported the king were known at the time as "Loyalists", "Tories", or "King's men". The Loyalists never controlled territory unless the British Army occupied it. They were typically older, less willing to break with old loyalties, and often connected to the Church of England; they included many established merchants with strong business connections throughout the Empire, as well as royal officials such as Thomas Hutchinson of Boston. + +There were 500 to 1,000 Black Loyalists, enslaved African Americans who escaped to British lines and supported Britain's cause via several means. Many of them died from various diseases, but the survivors were evacuated by the British to their remaining colonies in North America. + +The revolution could divide families, such as William Franklin, son of Benjamin Franklin and royal governor of the Province of New Jersey who remained loyal to the Crown throughout the war. He and his father never spoke again. Recent immigrants who had not been fully Americanized were also inclined to support the King, such as Flora MacDonald, a Scottish settler in the backcountry. + +After the war, the great majority of the half-million Loyalists remained in America and resumed normal lives. Some became prominent American leaders, such as Samuel Seabury. Approximately 46,000 Loyalists relocated to Canada; others moved to Britain (7,000), Florida, or the West Indies (9,000). The exiles represented approximately two percent of the total population of the colonies. Nearly all black loyalists left for Nova Scotia, Florida, or England, where they could remain free. Loyalists who left the South in 1783 took thousands of their slaves with them as they fled to the British West Indies. + +Neutrals + +A minority of uncertain size tried to stay neutral in the war. Most kept a low profile, but the Quakers were the most important group to speak out for neutrality, especially in Pennsylvania. The Quakers continued to do business with the British even after the war began, and they were accused of supporting British rule, "contrivers and authors of seditious publications" critical of the revolutionary cause. Most Quakers remained neutral, although a sizeable number nevertheless participated to some degree. + +Role of women + +Women contributed to the American Revolution in many ways and were involved on both sides. Formal politics did not include women, but ordinary domestic behaviors became charged with political significance as Patriot women confronted a war which permeated all aspects of political, civil, and domestic life. They participated by boycotting British goods, spying on the British, following armies as they marched, washing, cooking, and mending for soldiers, delivering secret messages, and even fighting disguised as men in a few cases, such as Deborah Samson. Mercy Otis Warren held meetings in her house and cleverly attacked Loyalists with her creative plays and histories. Many women also acted as nurses and helpers, tending to the soldiers' wounds and buying and selling goods for them. Some of these camp followers even participated in combat, such as Madam John Turchin who led her husband's regiment into battle. Above all, women continued the agricultural work at home to feed their families and the armies. They maintained their families during their husbands' absences and sometimes after their deaths. + +American women were integral to the success of the boycott of British goods, as the boycotted items were largely household articles such as tea and cloth. Women had to return to knitting goods and to spinning and weaving their own cloth—skills that had fallen into disuse. In 1769, the women of Boston produced 40,000 skeins of yarn, and 180 women in Middletown, Massachusetts wove of cloth. Many women gathered food, money, clothes, and other supplies during the war to help the soldiers. A woman's loyalty to her husband could become an open political act, especially for women in America committed to men who remained loyal to the King. Legal divorce, usually rare, was granted to Patriot women whose husbands supported the King. + +Other participants + +France and Spain + +In early 1776, France set up a major program of aid to the Americans, and the Spanish secretly added funds. Each country spent one million "livres tournaises" to buy munitions. A dummy corporation run by Pierre Beaumarchais concealed their activities. American Patriots obtained some munitions from the Dutch Republic as well, through the French and Spanish ports in the West Indies. Heavy expenditures and a weak taxation system pushed France toward bankruptcy. + +In 1777, Charles François Adrien le Paulmier, Chevalier d'Annemours, acting as a secret agent for France, made sure General George Washington was privy to his mission. He followed Congress around for the next two years, reporting what he observed back to France. The Treaty of Alliance between the French and the Americans followed in 1778, which led to more French money, matériel and troops being sent to the United States. + +Spain did not officially recognize the United States, but it was a French ally and it separately declared war on Britain on June 21, 1779. Bernardo de Gálvez, general of the Spanish forces in New Spain, also served as governor of Louisiana. He led an expedition of colonial troops to capture Florida from the British and to keep open a vital conduit for supplies. + +Germans + +Ethnic Germans served on both sides of the American Revolutionary War. As George III was also the Elector of Hanover, many supported the Loyalist cause and served as allies of the Kingdom of Great Britain; most notably rented auxiliary troops from German states such as the Landgraviate of Hessen-Kassel. + +American Patriots tended to represent such troops as mercenaries in propaganda against the British Crown. Even American historians followed suit, in spite of Colonial-era jurists drawing a distinction between auxiliaries and mercenaries, with auxiliaries serving their prince when sent to the aid of another prince, and mercenaries serving a foreign prince as individuals. By this distinction the troops which served in the American Revolution were auxiliaries. + +Other German individuals came to assist the American revolutionaries, most notably Friedrich Wilhelm von Steuben, who served as a general in the Continental Army and is credited with professionalizing that force, but most Germans who served were already colonists. Von Steuben's native Prussia joined the League of Armed Neutrality, and King Frederick II of Prussia was well appreciated in the United States for his support early in the war. He expressed interest in opening trade with the United States and bypassing English ports, and allowed an American agent to buy arms in Prussia. Frederick predicted American success, and promised to recognize the United States and American diplomats once France did the same. Prussia also interfered in the recruiting efforts of Russia and neighboring German states when they raised armies to send to the Americas, and Frederick II forbade enlistment for the American war within Prussia. All Prussian roads were denied to troops from Anhalt-Zerbst, which delayed reinforcements that Howe had hoped to receive during the winter of 1777–1778. + +However, when the War of the Bavarian Succession (1778-1779) erupted, Frederick II became much more cautious with Prussian/British relations. U.S. ships were denied access to Prussian ports, and Frederick refused to officially recognize the United States until they had signed the Treaty of Paris. Even after the war, Frederick II predicted that the United States was too large to operate as a republic, and that it would soon rejoin the British Empire with representatives in Parliament. + +Native Americans + +Most indigenous people rejected pleas that they remain neutral and instead supported the British Crown. The great majority of the 200,000 indigenous people east of the Mississippi distrusted the Americans and supported the British cause, hoping to forestall continued expansion of settlement into their territories. Those tribes closely involved in trade tended to side with the Patriots, although political factors were important as well. Some indigenous people tried to remain neutral, seeing little value in joining what they perceived to be a "white man's war", and fearing reprisals from whichever side they opposed. + +The great majority of indigenous people did not participate directly in the war, with the notable exceptions of warriors and bands associated with four of the Iroquois tribes in New York and Pennsylvania which allied with the British, and the Oneida and Tuscarora tribes among the Iroquois of central and western New York who supported the American cause. The British did have other allies, particularly in the regions of southwest Quebec on the Patriot's frontier. The British provided arms to indigenous people who were led by Loyalists in war parties to raid frontier settlements from the Carolinas to New York. These war parties managed to kill many settlers on the frontier, especially in Pennsylvania and New York's Mohawk Valley. + +In 1776, Cherokee war parties attacked American Colonists all along the southern Quebec frontier of the uplands throughout the Washington District, North Carolina (now Tennessee) and the Kentucky wilderness area. The Chickamauga Cherokee under Dragging Canoe allied themselves closely with the British, and fought on for an additional decade after the Treaty of Paris was signed. They would launch raids with roughly 200 warriors, as seen in the Cherokee–American wars; they could not mobilize enough forces to invade settler areas without the help of allies, most often the Creek. + +Joseph Brant (also Thayendanegea) of the powerful Mohawk tribe in New York was the most prominent indigenous leader against the Patriot forces. In 1778 and 1780, he led 300 Iroquois warriors and 100 white Loyalists in multiple attacks on small frontier settlements in New York and Pennsylvania, killing many settlers and destroying villages, crops, and stores. + +In 1779, the Continental Army forced the hostile indigenous people out of upstate New York when Washington sent an army under John Sullivan which destroyed 40 evacuated Iroquois villages in central and western New York. Sullivan systematically burned the empty villages and destroyed about 160,000 bushels of corn that composed the winter food supply. The Battle of Newtown proved decisive, as the Patriots had an advantage of three-to-one, and it ended significant resistance; there was little combat otherwise. Facing starvation and homeless for the winter, the Iroquois fled to Canada. The British resettled them in Ontario, providing land grants as compensation for some of their losses. + +At the peace conference following the war, the British ceded lands which they did not really control, and which they did not consult about with their indigenous allies during the treaty negotiations. They transferred control to the United States of all the land south of the Great Lakes east of the Mississippi and north of Florida. Calloway concludes: + +The British did not give up their forts until 1796 in the Ohio country and Illinois country; they kept alive the dream of forming an allied indigenous nation there, which they referred to an "Indian barrier state". That goal was one of the causes of the War of 1812. + +Black Americans + +Free blacks in the New England Colonies and Middle Colonies in the North as well as Southern Colonies fought on both sides of the War, but the majority fought for the Patriots. Gary Nash reports that there were about 9,000 black veteran Patriots, counting the Continental Army and Navy, state militia units, privateers, wagoneers in the Army, servants to officers, and spies. Ray Raphael notes that thousands did join the Loyalist cause, but "a far larger number, free as well as slave, tried to further their interests by siding with the patriots." Crispus Attucks was one of the five people killed in the Boston Massacre in 1770 and is considered the first American casualty for the cause of independence. + +The effects of the war were more dramatic in the South. Tens of thousands of slaves escaped to British lines throughout the South, causing dramatic losses to slaveholders and disrupting cultivation and harvesting of crops. For instance, South Carolina was estimated to have lost about 25,000 slaves to flight, migration, or death which amounted to a third of its slave population. From 1770 to 1790, the black proportion of the population (mostly slaves) in South Carolina dropped from 60.5 percent to 43.8 percent, and from 45.2 percent to 36.1 percent in Georgia. + +During the war, the British commanders attempted to weaken the Patriots by issuing proclamations of freedom to their slaves. In the November 1775 document known as Dunmore's Proclamation Virginia royal governor, Lord Dunmore recruited black men into the British forces with the promise of freedom, protection for their families, and land grants. Some men responded and briefly formed the British Ethiopian Regiment. Historian David Brion Davis explains the difficulties with a policy of wholesale arming of the slaves: + +Davis underscores the British dilemma: "Britain, when confronted by the rebellious American colonists, hoped to exploit their fear of slave revolts while also reassuring the large number of slave-holding Loyalists and wealthy Caribbean planters and merchants that their slave property would be secure". The Americans, however, accused the British of encouraging slave revolts, with the issue becoming one of the 27 colonial grievances. + +The existence of slavery in the American colonies had attracted criticism from both sides of the Atlantic as many could not reconcile the existence of the institution with the egalitarian ideals espoused by leaders of the Revolution. British writer Samuel Johnson wrote "how is it we hear the loudest yelps for liberty among the drivers of the Negroes?" in a text opposing the grievances of the colonists. Referring to this contradiction, English abolitionist Thomas Day wrote in a 1776 letter that African American writer Lemuel Haynes expressed similar viewpoints in his essay Liberty Further Extended where he wrote that "Liberty is Equally as pre[c]ious to a Black man, as it is to a white one". Thomas Jefferson unsuccessfully attempted to include a section in the Declaration of Independence which asserted that King George III had "forced" the slave trade onto the colonies. Despite the turmoil of the period, African-Americans contributed to the foundation of an American national identity during the Revolution. Phyllis Wheatley, an African-American poet, popularized the image of Columbia to represent America. She came to public attention when her Poems on Various Subjects, Religious and Moral appeared in 1773, and received praise from George Washington. + +The 1779 Philipsburg Proclamation expanded the promise of freedom for black men who enlisted in the British military to all the colonies in rebellion. British forces gave transportation to 10,000 slaves when they evacuated Savannah and Charleston, carrying through on their promise. They evacuated and resettled more than 3,000 Black Loyalists from New York to Nova Scotia, Upper Canada, and Lower Canada. Others sailed with the British to England or were resettled as freedmen in the West Indies of the Caribbean. But slaves carried to the Caribbean under control of Loyalist masters generally remained slaves until British abolition of slavery in its colonies in 1833–1838. More than 1,200 of the Black Loyalists of Nova Scotia later resettled in the British colony of Sierra Leone, where they became leaders of the Krio ethnic group of Freetown and the later national government. Many of their descendants still live in Sierra Leone, as well as other African countries. + +Effects of the Revolution + +After the Revolution, genuinely democratic politics became possible in the former American colonies. The rights of the people were incorporated into state constitutions. Concepts of liberty, individual rights, equality among men and hostility toward corruption became incorporated as core values of liberal republicanism. The greatest challenge to the old order in Europe was the challenge to inherited political power and the democratic idea that government rests on the consent of the governed. The example of the first successful revolution against a European empire, and the first successful establishment of a republican form of democratically elected government, provided a model for many other colonial peoples who realized that they too could break away and become self-governing nations with directly elected representative government. + +Interpretations +Interpretations vary concerning the effect of the Revolution. Historians such as Bernard Bailyn, Gordon Wood, and Edmund Morgan view it as a unique and radical event which produced deep changes and had a profound effect on world affairs, such as an increasing belief in the principles of the Enlightenment. These were demonstrated by a leadership and government that espoused protection of natural rights, and a system of laws chosen by the people. John Murrin, by contrast, argues that the definition of "the people" at that time was mostly restricted to free men who passed a property qualification. This view argues that any significant gain of the revolution was irrelevant in the short term to women, black Americans and slaves, poor white men, youth, and Native Americans. + +Gordon Wood states: +The American Revolution was integral to the changes occurring in American society, politics and culture .... These changes were radical, and they were extensive .... The Revolution not only radically changed the personal and social relationships of people, including the position of women, but also destroyed aristocracy as it'd been understood in the Western world for at least two millennia. + +Edmund Morgan has argued that, in terms of long-term impact on American society and values: +The Revolution did revolutionize social relations. It did displace the deference, the patronage, the social divisions that had determined the way people viewed one another for centuries and still view one another in much of the world. It did give to ordinary people a pride and power, not to say an arrogance, that have continued to shock visitors from less favored lands. It may have left standing a host of inequalities that have troubled us ever since. But it generated the egalitarian view of human society that makes them troubling and makes our world so different from the one in which the revolutionists had grown up. + +Inspiring other independence movements and revolutions + +The first shot of the American Revolution at the Battle of Lexington and Concord is referred to as the "shot heard 'round the world" due to its historical and global significance. The Revolutionary War victory not only established the United States as the first modern constitutional republic, but marked the transition from an age of monarchy to a new age of freedom by inspiring similar movements worldwide. The American Revolution was the first of the "Atlantic Revolutions": followed most notably by the French Revolution, the Haitian Revolution, and the Latin American wars of independence. Aftershocks contributed to rebellions in Ireland, the Polish–Lithuanian Commonwealth, and the Netherlands. + +The U.S. Constitution, drafted shortly after independence, remains the world's oldest written constitution, and has been emulated by other countries, in some cases verbatim. Some historians and scholars argue that the subsequent wave of independence and revolutionary movements has contributed to the continued expansion of democratic government; 144 countries, representing two-third of the world's population, are full or partially democracies of same form. + +The Dutch Republic, also at war with Britain, was the next country after France to sign a treaty with the United States, on October 8, 1782. On April 3, 1783, Ambassador Extraordinary Gustaf Philip Creutz, representing King Gustav III of Sweden, and Benjamin Franklin, signed a Treaty of Amity and Commerce with the U.S. + +The Revolution had a strong, immediate influence in Great Britain, Ireland, the Netherlands, and France. Many British and Irish Whigs in Parliament spoke glowingly in favor of the American cause. In Ireland, the Protestant minority who controlled Ireland demanded self-rule. Under the leadership of Henry Grattan, the Irish Patriot Party forced the reversal of mercantilist prohibitions against trade with other British colonies. The King and his cabinet in London could not risk another rebellion on the American model, and so made a series of concessions to the Patriot faction in Dublin. Armed volunteer units of the Protestant Ascendancy were set up ostensibly to protect against an invasion from France. As had been in colonial America, so too in Ireland now the King no longer had a monopoly of lethal force. + +For many Europeans, such as the Marquis de Lafayette, who later were active during the era of the French Revolution, the American case along with the Dutch Revolt (end of the 16th century) and the 17th century English Civil War, was among the examples of overthrowing an old regime. The American Declaration of Independence influenced the French Declaration of the Rights of Man and of the Citizen of 1789. The spirit of the Declaration of Independence led to laws ending slavery in all the Northern states and the Northwest Territory, with New Jersey the last in 1804. States such as New Jersey and New York adopted gradual emancipation, which kept some people as slaves for more than two decades longer. + +Status of African Americans + +During the revolution, the contradiction between the Patriots' professed ideals of liberty and the institution of slavery generated increased scrutiny of the latter. As early as 1764, the Boston Patriot leader James Otis, Jr. declared that all men, "white or black", were "by the law of nature" born free. Anti-slavery calls became more common in the early 1770s. In 1773, Benjamin Rush, the future signer of the Declaration of Independence, called on "advocates for American liberty" to oppose slavery, writing, "The plant of liberty is of so tender a nature that it cannot thrive long in the neighborhood of slavery.". The contradiction between calls for liberty and the continued existence of slavery also opened up the Patriots to charges of hypocrisy. In 1775, the English Tory writer Samuel Johnson asked, "How is it that we hear the loudest yelps for liberty among the drivers of negroes?" + +In the late 1760s and early 1770s, several colonies, including Massachusetts and Virginia, attempted to restrict the slave trade, but were prevented from doing so by royally appointed governors. In 1774, as part of a broader non-importation movement aimed at Britain, the Continental Congress called on all the colonies to ban the importation of slaves, and the colonies passed acts doing so. In 1775, the Quakers founded first antislavery society in the Western world, the Pennsylvania Abolition Society. + +In the first two decades after the American Revolution, state legislatures and individuals took actions to free slaves, in part based on revolutionary ideals. Northern states passed new constitutions that contained language about equal rights or specifically abolished slavery; some states, such as New York and New Jersey, where slavery was more widespread, passed laws by the end of the 18th century to abolish slavery by a gradual method. By 1804, all the northern states had passed laws outlawing slavery, either immediately or over time. In New York, the last slaves were freed in 1827. Indentured servitude (temporary slavery), which had been widespread in the colonies (half the population of Philadelphia had once been bonded servants) dropped dramatically, and disappeared by 1800. + +No southern state abolished slavery, but for a period individual owners could free their slaves by personal decision, often providing for manumission in wills but sometimes filing deeds or court papers to free individuals. Numerous slaveholders who freed their slaves cited revolutionary ideals in their documents; others freed slaves as a reward for service. Records also suggest that some slaveholders were freeing their own mixed-race children, born into slavery to slave mothers. The number of free blacks as a proportion of the black population in the upper South increased from less than 1 percent to nearly 10 percent between 1790 and 1810 as a result of these actions. Nevertheless, slavery continued in the South, where it became a "peculiar institution", setting the stage for future sectional conflict between North and South over the issue. + +Thousands of free Blacks in the northern states fought in the state militias and Continental Army. In the south, both sides offered freedom to slaves who would perform military service. Roughly 20,000 slaves fought in the American Revolution. + +Status of American women + +The democratic ideals of the Revolution inspired changes in the roles of women. + +The concept of republican motherhood was inspired by this period and reflects the importance of revolutionary republicanism as the dominant American ideology. It assumed that a successful republic rested upon the virtue of its citizens. Women were considered to have the essential role of instilling their children with values conducive to a healthy republic. During this period, the wife's relationship with her husband also became more liberal, as love and affection instead of obedience and subservience began to characterize the ideal marital relationship. In addition, many women contributed to the war effort through fundraising and running family businesses without their husbands. + +The traditional constraints gave way to more liberal conditions for women. Young people had more freedom to choose their spouses and more often used birth control to regulate the size of their families. Society emphasized the role of mothers in child rearing, especially the patriotic goal of raising republican children rather than those locked into aristocratic value systems. There was more permissiveness in child-rearing. Patriot women married to Loyalists who left the state could get a divorce and obtain control of the ex-husband's property. + +Whatever gains they had made, however, women still found themselves subordinated, legally and socially, to their husbands, disfranchised and usually with only the role of mother open to them. But, some women earned livelihoods as midwives and in other roles in the community not originally recognized as significant by men. + +Abigail Adams expressed to her husband, the president, the desire of women to have a place in the new republic: + +The Revolution sparked a discussion on the rights of woman and an environment favorable to women's participation in politics. Briefly the possibilities for women's rights were highly favorable, but a backlash led to a greater rigidity that excluded women from politics. + +For more than thirty years, however, the 1776 New Jersey State Constitution gave the vote to "all inhabitants" who had a certain level of wealth, including unmarried women and blacks (not married women because they could not own property separately from their husbands), until in 1807, when that state legislature passed a bill interpreting the constitution to mean universal white male suffrage, excluding paupers. + +Loyalist expatriation + +Tens of thousands of Loyalists left the United States following the war, and Maya Jasanoff estimates as many as 70,000. Some migrated to Britain, but the great majority received land and subsidies for resettlement in British colonies in North America, especially Quebec (concentrating in the Eastern Townships), Prince Edward Island, and Nova Scotia. Britain created the colonies of Upper Canada (Ontario) and New Brunswick expressly for their benefit, and the Crown awarded land to Loyalists as compensation for losses in the United States. Nevertheless, approximately eighty-five percent of the Loyalists stayed in the United States as American citizens, and some of the exiles later returned to the U.S. Patrick Henry spoke of the issue of allowing Loyalists to return as such: "Shall we, who have laid the proud British lion at our feet, be frightened of its whelps?" His actions helped secure return of the Loyalists to American soil. + +Commemorations + +The American Revolution has a central place in the American memory as the story of the nation's founding. It is covered in the schools, memorialized by two national holidays, Washington's Birthday in February and Independence Day in July, and commemorated in innumerable monuments. George Washington's estate at Mount Vernon was one of the first national pilgrimages for tourists and attracted 10,000 visitors a year by the 1850s. + +The Revolution became a matter of contention in the 1850s in the debates leading to the American Civil War (1861–1865), as spokesmen of both the Northern United States and the Southern United States claimed that their region was the true custodian of the legacy of 1776. The United States Bicentennial in 1976 came a year after the American withdrawal from the Vietnam War, and speakers stressed the themes of renewal and rebirth based on a restoration of traditional values. + +Today, more than 100 battlefields and historic sites of the American Revolution are protected and maintained by the government. The National Park Service alone manages and maintains more than 50 battlefield parks and many other sites such as Independence Hall that are related to the Revolution, as well as the residences, workplaces and meeting places of many Founders and other important figures. The private American Battlefield Trust uses government grants and other funds to preserve almost 700 acres of battlefield land in six states, and the ambitious private recreation/restoration/preservation/interpretation of over 300 acres of pre-1790 Colonial Williamsburg was created in the first half of the 20th century for public visitation. + +See also + List of films about the American Revolution + List of George Washington articles + List of television series and miniseries about the American Revolution + Museum of the American Revolution + +Notes + +References + +General sources + +Bibliography + +Reference works + + Barnes, Ian, and Charles Royster.
