February 21 – Charles signs a treaty and is proclaimed King of Albania. He promises to protect the nobles and to honor the privileges they have from the Byzantine Empire. The treaty declares the union between the Kingdom of Albania (Latin: Regnum Albanie) and the Kingdom of Sicily, under Charles' rule. He appoints Gazo Chinard as his vicar-general, and sends his Sicilian fleet to Achaea, to defend the principality against Byzantine attacks.[1]
November – Charles I orders his officials to take all Genoese prisoner within his territories, except for the Guelphs and to seize their property. The Sicilian fleet occupies Ajaccio on Corsica. Pope Gregory X condemns the aggressive policy of Charles and proposes that the Genoese elect Guelph officials.[4]
May 22 – King Hugh III of Cyprus ("the Great") signs a peace with Sultan Baibars, Mamluk ruler of Egypt, at Caesarea. The Kingdom of Jerusalem is guaranteed for 10 years the possession of its present lands, which consists mainly of the narrow coastal plain from Acre to Sidon, together with the right to use without hindrance the pilgrim-road to Nazareth. The County of Tripoli is safeguarded by the peace treaty.[6]
June 16 – The Lord Edward, heir to the English throne, prevents an assassination attempt on himself at Acre. A Syrian Nizari (or Assassin) supposedly sent by Baibars penetrates into the prince's chamber and stabs him with a poisoned dagger. The wound is not fatal, but Edward is seriously ill for some months. Baibars hastens to dissociate himself from the deed by sending his congratulations on the prince's escape.[7]
August 18 – Nubian forces sack the Egyptian Red Sea outpost of Aydhab and raid the southern frontier city of Aswan. In return, Baibars invades the kingdom of Makuria.[8]
