Isabella of Ibelin, Queen of Cyprus and Jerusalem

Isabella of Ibelin (1241–1324) was queen of Cyprus and Jerusalem by marriage to Hugh III of Cyprus.

Isabella was the daughter of Guy of Ibelin, marshal and constable of the Kingdom of Cyprus. She married Hugh of Antioch, who succeeded his childless cousin Hugh II as king of Cyprus in 1267 thanks to her family's connections. In 1268, her husband became king of Jerusalem too. He died in 1284 and the crowns passed to their sons, first John I and shortly after to Henry II.

When her son Amalric seized power in 1306, Queen Isabella and her brother Philip unsuccessfully supported her older son King Henry. Amalric was murdered on 5 June 1310, and another son, Aimery, was proclaimed governor in his stead. But by 11 June, supporters of the imprisoned king contacted their mother, Queen Isabella, papal representatives, and Aimery's party. Aimery was outnumbered and agreed with his supporters to restore Henry in return for Isabella's promise to persuade Henry to pardon them and to ratify legal transactions they made. Envoys reported to King James II of Aragon, husband of Isabella's daughter Maria, that Isabella and Philip dominated Henry's court in the rest of his reign.
