Hugh III of Cyprus (b. 1235)
Hugh III (French: Hugues; c. 1235 – 24 March 1284), also called Hugh of Antioch-Lusignan and the Great, was the king of Cyprus from 1267 and king of Jerusalem from 1268. Born into the family of the princes of Antioch, he effectively ruled as regent for underage kings Hugh II of Cyprus and Conrad III of Jerusalem for several years. Prevailing over the claims of his cousin Hugh of Brienne, he succeeded both young monarchs upon their deaths and appeared poised to be an effective political and military leader.

As the first king of Jerusalem to reside in the kingdom since the 1220s, Hugh tried to restore the royal domain, reassert royal authority over the increasingly independent mainland vassals, and prevent further loss of territory to the Egyptian Mamluks. Marital alliances brought to him steadfast loyalty of the most powerful noble families, the Ibelins and the Montforts, but his efforts on the mainland were doomed to failure by the hostility of the Venetian merchants and the Knights Templar. His insular vassals, on the other hand, resented his determination to deploy Cypriot armies in defense of the Crusader states. In 1275 he failed to establish himself as regent of the County of Tripoli.

Most problematically, Hugh's right to the throne of Jerusalem was challenged by his aunt Maria of Antioch, who sold her claim to Charles I of Anjou in 1277. With the support of the Venetians and the Templars, Charles promptly took Acre, the last city on the mainland that belonged directly to the king. After two unsuccessful attempts to regain Acre, Hugh died in Tyre, a mainland city held by the loyal Montforts. He was succeeded by his son John I.
