He is succeeded by his 24-year-old son Manuel I, who is chosen as his successor, in preference to his elder surviving brother Isaac. Manuel dispatches John Axouchos, his commander-in-chief (megas domestikos), to Constantinople ahead of him – with orders to arrest Isaac in the Great Palace.^[1]

November 13 – King Fulk of Jerusalem dies after a hunting accident in Acre. He is succeeded by his 13-year-old son Baldwin III – who is crowned as co-ruler alongside his mother, Queen Melisende on Christmas Day. Due to the political situation the Crusader States of Tripoli, Antioch and Edessa assert their independence. Raymond of Antioch demands the return of Cilicia to his principality and invades the province.^[2]
