Thomas Becket was murdered in Canterbury Cathedral
On this day · 29 December 1170
Four of King Henry II's knights cut down the Archbishop of Canterbury at his own altar, creating one of medieval Europe's most powerful martyrs.
On 29 December 1170, four knights loyal to King Henry II confronted Archbishop Thomas Becket inside Canterbury Cathedral. The two men had once been close, but their friendship shattered over where the king’s power ended and the Church’s began. When Becket refused to pardon men he had excommunicated, the confrontation turned lethal — one knight sliced off the top of his head with a sword.
Henry, allegedly raging in France, is said to have asked, “Will no one rid me of this turbulent priest?” Whether he meant it as an order, no one knows.
What followed was swift and astonishing. Locals reported miracles tied to cloth soaked in Becket’s blood, and his tomb became the most popular pilgrimage site in late medieval Britain. Pope Alexander III canonized him in 1173, barely three years after the killing — lightning speed by medieval standards. A murder meant to silence a priest instead made him a saint.
