Thomas Becket (1119 - 1170). Thomas Becket, also known as Saint Thomas of Canterbury, Thomas of London and later Thomas à Becket, was Archbishop of Canterbury from 1162 until his murder in 1170. He is venerated as a saint and martyr by both the Catholic Church and the Anglican Communion. He engaged in conflict with Henry II, King of England, over the rights and privileges of the Church and was murdered by followers of the king in Canterbury Cathedral. Soon after his death, he was canonised by Pope Alexander III. The main sources for the life of Becket are a number of biographies written by contemporaries. A few of these documents are by unknown writers, although traditional historiography has given them names. The known biographers are John of Salisbury, Edward Grim, Benedict of Peterborough, William of Canterbury, William fitzStephen, Guernes of Pont-Sainte-Maxence, Robert of Cricklade, Alan of Tewkesbury, Benet of St Albans, and Herbert of Bosham. The other biographers, who remain anonymous, are generally given the pseudonyms of Anonymous I, Anonymous II, and Anonymous III. Besides these accounts, there are also two other accounts that are likely contemporary that appear in the Quadrilogus II and the Thómas saga erkibyskups. Besides these biographies, there is also the mention of the events of Becket's life in the chroniclers of the time. These include Robert of Torigni's work, Roger of Howden's Gesta Regis Henrici Secundi and Chronica, Ralph Diceto's works, William of Newburgh's Historia Rerum, and Gervase of Canterbury's works. Becket was born about 1119, or in 1120 according to later tradition. He was born in Cheapside, London, on 21 December, which was the feast day of St Thomas the Apostle. He was the son of Gilbert and Matilda Beket. Gilbert's father was from Thierville in the lordship of Brionne in Normandy, and was either a small landowner or a petty knight. Matilda was also of Norman descent, and her family may have originated near Caen. Gilbert was perhaps related to Theobald of Bec, whose family also was from Thierville. Gilbert began his life as a merchant, perhaps in textiles, but by the 1120s he was living in London and was a property owner, living on the rental income from his properties. He also served as the sheriff of the city at some point. They were buried in Old St Paul's Cathedral. One of Becket's father's wealthy friends, Richer de L'Aigle, often invited Thomas to his estates in Sussex where Becket was exposed to hunting and hawking. According to Grim, Becket learned much from Richer, who was later a signatory of the Constitutions of Clarendon against Thomas. Beginning when he was 10, Becket was sent as a student to Merton Priory southwest of the city in Surrey and later attended a grammar school in London, perhaps the one at St Paul's Cathedral. He did not study any subjects beyond the trivium and quadrivium at these schools. Later, he spent about a year in Paris around age 20. He did not, however, study canon or civil law at this time and his Latin skill always remained somewhat rudimentary. Some time after Becket began his schooling, Gilbert Beket suffered financial reverses, and the younger Becket was forced to earn a living as a clerk. Gilbert first secured a place for his son in the business of a relative, Osbert Huitdeniers, and then later Becket acquired a position in the household of Theobald of Bec, by now the Archbishop of Canterbury. Theobald entrusted him with several important missions to Rome and also sent him to Bologna and Auxerre to study canon law. Theobald in 1154 named Becket Archdeacon of Canterbury, and other ecclesiastical offices included a number of benefices, prebends at Lincoln Cathedral and St Paul's Cathedral, and the office of Provost of Beverley. His efficiency in those posts led to Theobald recommending him to King Henry II for the vacant post of Lord Chancellor, to which Becket was appointed in January 1155. As Chancellor, Becket enforced the king's traditional sources of revenue that were exacted from all landowners, including churches and bishoprics. King Henry sent his son Henry to live in Becket's household, it being the custom then for noble children to be fostered out to other noble houses. Becket was nominated as Archbishop of Canterbury in 1162, several months after the death of Theobald. His election was confirmed on 23 May 1162 by a royal council of bishops and noblemen. Henry may have hoped that Becket would continue to put the royal government first, rather than the church. However, the famous transformation of Becket into an ascetic occurred at this time.
