Thomas Becket Murdered in Canterbury Cathedral

Four knights murdered Archbishop Thomas Becket on the altar of Canterbury Cathedral on December 29, 1170, acting on what they interpreted as King Henry II's frustrated outburst against his former ally. The words Henry reportedly spoke, "Will no one rid me of this turbulent priest?" or some variation, were likely an expression of exasperation rather than a direct order. The four knights, Reginald FitzUrse, Hugh de Morville, William de Tracy, and Richard le Breton, rode to Canterbury, confronted Becket in the cathedral during Vespers, and struck him down with swords. The killing was savage: the final blow split Becket's skull and spilled his brains on the cathedral floor. The murder shocked all of Christendom. Becket and Henry had been close allies before Henry appointed him Archbishop of Canterbury in 1162, expecting Becket to be a compliant tool of royal authority over the Church. Instead, Becket embraced his new role with fanatical devotion, defending Church prerogatives against the king's attempts to bring clerical courts under royal jurisdiction. The quarrel between them, codified in the Constitutions of Clarendon in 1164, went to the heart of medieval governance: who held supreme authority in a Christian kingdom, the king or the Church? Becket was canonized just three years after his death, and Canterbury became medieval Europe's premier pilgrimage destination, generating enough revenue to rebuild the cathedral and sustain the city's economy for centuries. Henry was forced into a humiliating public penance, walking barefoot through Canterbury while monks flogged him. The murder subordinated English royal authority to the Church for generations and established the principle that even kings could not kill their way out of ecclesiastical disputes.
