Parallels have been drawn between the Brexit debate and the arguments that raged in the 12th century over sovereignty, with Pope Gregory VII (also known as Hildebrand) seeking to assert the authority of the Church over all the secular rulers of Christendom. Fortunately, even in the most fraught discussions about whether national or EU courts should have supremacy in any post-Brexit trade deal, no politician has inflicted a fatal sword blow on an opponent. It was different in December 1170, when Henry II is said to have lost his temper on learning that Becket had excommunicated the Archbishop of York and three other bishops because they had supported the king in an escalating row over whether monks and priests should be subject to secular or ecclesiastical courts.

The king is said to have described the members of his household as ‘miserable drones and traitors’ for allowing ‘their lord be treated with such shameful contempt by a low- born cleric’. Later historians polished the phrase to give it greater rhetorical force. The claim that the king asked ‘Who will deliver me from this turbulent priest?’ first appears in the History of the Life of King Henry the Second (1772) by George Lyttleton, and the phrase has been associated with Becket’s murder ever since.

From martyrdom to miracles
Whatever words the king actually used, and whether he meant them rhetorically (as he subsequently claimed) or as a subtly veiled command, Henry II was realistic enough to understand that he had lost the argument by resorting to violence, and he accepted the blame for the assassination. The Church regarded Becket’s murder as all the more heinous because it took place in the house of God. That was probably not an accident. According to the account written by Edward Grim, who witnessed the murder and published his version as Vita Sancti Thomae (Life of St Thomas, c.1180), Becket fled to the safety of the cathedral once he was aware that an attempt would be made on his life. Perhaps the Archbishop calculated that if he could not avoid martyrdom, he could at least maximise the shock value by forcing the assassins to kill him in a place of holiness and sanctuary.
