Thomas Becket. 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 Re
