On the 29th December 1170, Thomas Becket – the Archbishop of Canterbury – was murdered in front of the altar of Canterbury Cathedral. He had been appointed by Henry II to the most important religious position in England in 1162, but was slain after some of the king’s men interpreted one of their ruler’s angry outbursts as the desire to have Becket killed.
Thomas Becket was appointed Chancellor by Henry in 1155. In this job he proved himself to be a loyal member of the king’s court and so when Theobald, the existing Archbishop of Canterbury died, Henry saw his chance to dominate the church by appointing Becket to succeed him.
Having a loyal friend in the most senior religious position in England made sense to Henry. However, as Archbishop of Canterbury, Becket’s allegiance quickly switched to siding with the church. This frustrated Henry, who asked Becket to sign the Constitutions of Clarendon in 1164 to extend the king’s authority over the clergy. Becket refused, and shortly after being summoned to the king to explain his actions fled to France.
Becket returned in 1170 but, after excommunicating members of the clergy for supporting Henry, found himself the target of an angry outburst by the king – which almost certainly wasn’t “Who will rid me of this troublesome priest?” Whatever Henry did say, however, it was enough to encourage four knights to travel to Canterbury and kill him inside the Cathedral. It is said that the fatal blow split his skull. Becket was canonised by the Pope barely two years after the murder, and in 1174 the king himself walked barefoot to Canterbury in penance.
