Isabella of Ibelin, Queen of Cyprus
Isabella of Ibelin (1241–1324) was queen of Cyprus and Jerusalem by marriage to Hugh III. The daughter of Guy d'Ibelin, constable of Cyprus, she wed Hugh of Antioch in 1255; her kinsmen helped him succeed the childless Hugh II in 1267.
Widowed in 1284, she saw her sons John I and Henry II crowned. When Amalric deposed Henry in 1306, she and her brother Philip backed the king; after Amalric's murder in 1310 she secured Henry's restoration.
