By placeEdit


  • Winter – Egyptian forces led by Saladin invade Palestine and besiege Darum on the Mediterranean coast. Its defenses are weak and though Saladin has no siege-engines with him, its fall seems imminent. King Amalric I withdraws his Templar garrison from Gaza, to assist him in defending Darum. Saladin raises the siege and marches on Gaza, where he captures the lower town (despite the stiff resistance ordered by Lord Miles of Plancy), and massacres the inhabitants. But the citadel is too strong for Saladin, and he is forced to retreat back to Egypt.[1]
  • Saladin sends an Egyptian squadron up the Gulf of Akaba, which captures the Crusader outpost of Aila, at the head of the Gulf.[2]


  • June 14 – King Henry II has his 15-year-old son Henry (the Young King) crowned by Roger, archbishop of York, as Junior King and heir to the English throne. The Becket dispute forces Henry to reconcile his quarrel with Thomas Becket, archbishop of Canterbury, who finds this act a violation of Canterbury's privilege of coronation.
  • William Marshal is appointed head of the household of Henry (the Young King). He is responsible for protecting, training and running the military household of the heir.
  • July 22 – Henry II and Thomas Becket meet near Fréteval, France, where they come to an agreement to end their differences. This results in Becket's partial restoration.
  • December 1 – Henry II sends word, saying that the conflict with Thomas Becket is at an end, and his lands will be restored. Becket returns to England, landing at Sandwich.
  • December 25 – Thomas Becket takes to the pulpit at Canterbury Cathedral and gives his sermon. At the end of the sermon, he excommunicates several of his enemies.
  • This is the earliest date for the making of Cheddar Cheese in Somerset (this according to a pipe roll of Henry II, who purchases 10,240 lb of Cheddar at a farthing per pound).
  • December 29 – Thomas Becket is assassinated by knights in Canterbury Cathedral, after his refusal to be arrested for breaking his agreement with Henry II.[3]
