The Archbishop Murdered At His Own Altar

The murder of Thomas Becket in Canterbury Cathedral on the 29th of December 1170 is one of the most famous and shocking crimes in English history — the killing of an archbishop at his own altar, on the effective wish of a king who had once been his closest friend. It sent a wave of horror across all of Christendom, and it made Becket a saint.

Thomas Becket and Henry II began not as enemies, but as the best of friends. Becket was the clever, charming, ambitious son of a London merchant, and when the young, energetic Henry became King of England, he took a liking to Becket and made him his Chancellor — his right-hand man. The two were inseparable. They worked together, hunted together, played chess together. Chroniclers said the King and his Chancellor “had but one heart and one mind.” Henry trusted Becket completely.

So in 1162, when the position of Archbishop of Canterbury — the most powerful churchman in all of England — fell vacant, Henry saw the perfect opportunity. He would make his loyal friend Becket the archbishop. That way, the King reasoned, he would finally have control over the troublesome Church, with his own man in charge of it.

The Horror

But Henry had made a catastrophic miscalculation. Because the moment Thomas Becket became archbishop, he transformed. He gave up his lavish lifestyle, embraced piety, and — instead of being the King’s puppet — became the single most fierce and stubborn defender of the rights and independence of the Church against the crown. The friend became the adversary.

The two men, once so close, fell into a long and bitter quarrel over the fundamental question of power: who was supreme in England — the King, or the Church? They clashed over whether the King’s courts could try priests, over the boundaries of royal and papal authority, over everything. The fight grew so vicious that Becket was forced to flee England and live in exile in France for six years, as the feud between the former friends poisoned the whole kingdom.

Finally, in 1170, a shaky, exhausted truce was patched together, and Becket returned to England to cheering crowds. But it collapsed almost immediately. Becket, as unbending as ever, excommunicated the bishops who had taken part in the coronation of Henry’s son — a ceremony that was the archbishop’s sacred right. To Henry, this was the last straw: his old friend defying and humiliating him yet again.

And Henry, who was in Normandy when the news reached him, flew into one of his famous, towering rages. And in that fury, he burst out with the words that would echo through history — words that, according to tradition, were something like: “Will no one rid me of this turbulent priest?”

He almost certainly did not mean it as a literal command to murder. It was the reckless roar of a furious man. But four of his knights — Reginald FitzUrse, Hugh de Morville, William de Tracy, and Richard le Breton — took the King at his word. Believing they were doing Henry’s will and would win his favour, the four armed themselves, slipped across the Channel, and rode hard for Canterbury.

On the afternoon of the 29th of December 1170, they arrived at Canterbury Cathedral. They first confronted Becket and demanded he submit to the King and absolve the bishops. He refused. The knights withdrew to arm themselves fully, and Becket’s terrified monks hustled him into the cathedral itself, bolting the doors, believing that surely, in the house of God, in a place of sacred sanctuary, no one would dare commit violence. Becket, with extraordinary courage, ordered the doors reopened, declaring that a church was not a fortress and should not be barred.

The knights burst in, swords drawn, as the monks were preparing for Vespers, the evening prayers. They found the archbishop near the altar. And Thomas Becket did not run, and he did not beg. He stood his ground and faced them.

What followed was witnessed and recorded in horrifying detail by a monk named Edward Grim, who was standing right beside Becket and was himself wounded trying to shield him. The knights seized the archbishop and tried to drag him from the cathedral, but Becket clung to a pillar and would not be moved, praying and commending his soul to God. Then the swords came down. The first blow struck Becket’s head — and glanced off the arm of Edward Grim as he tried to protect him. More blows rained down as Becket sank to his knees. And then came the terrible, final stroke: a sword blow of such savage force that it sliced the entire crown off the top of Becket’s skull. Grim recorded the ghastly image of the blood and the brain spilling onto the cathedral floor. One of the knights placed his foot on the dead archbishop’s neck, and they left him where he lay, cut down before the altar of his own cathedral.

THE MODERN RELIC The reaction was immediate, and it was volcanic. The murder of an archbishop — the head of the English Church — inside a cathedral, in a sacred space of sanctuary, was an act of almost unimaginable sacrilege. All of Christian Europe was shaken to its core. Becket was instantly hailed as a martyr. Almost at once, local people began collecting cloth dipped in his blood, and reports of miraculous healings spread like wildfire. In barely two years, in 1173, the Pope declared Thomas Becket a saint.

And King Henry II — whatever he had truly meant by those angry words — was overwhelmed by the horror and the guilt, and the political catastrophe of being blamed for the murder. In 1174, the King of England performed one of the most extraordinary acts of royal penance in history. He walked to Canterbury Cathedral barefoot, dressed in sackcloth, and knelt at the tomb of his murdered friend — and there he submitted to being scourged, whipped by the monks of Canterbury, as public penance for the death he had caused. The most powerful king in England, beaten at the tomb of the man his words had killed.

The relic is Canterbury Cathedral itself, one of the most sacred and visited places in England, and you can stand on the very spot. Becket’s shrine became the most important pilgrimage destination in all of England, drawing tens of thousands of pilgrims for centuries — the pilgrimage immortalised in Geoffrey Chaucer’s The Canterbury Tales. The magnificent shrine was destroyed by another Henry — Henry VIII — during the Reformation, who had Becket’s bones scattered and even declared the long-dead saint a traitor. But the site remains. In the north transept of Canterbury Cathedral, the exact spot where Thomas Becket was cut down is marked and known as “the Martyrdom.” And at the far east end, the Corona chapel was built specifically to house the relic of the sliced-off crown of Becket’s skull. Today, where his golden shrine once blazed with jewels, a single candle burns on the bare stone floor — marking the place where a king’s six angry words led four knights to butcher an archbishop at his altar, and turned an old friend into England’s most famous saint.
