Constantine III of Armenia

Constantine III (1313–1362), son of Baldwin, Lord of Neghir, was king of Armenian Cilicia from 1344. The main Hethumid line had ended with the murder of Leo IV in 1341; his successor Constantine II fell to an uprising in 1344, and Constantine III took the crown.

He tried to wipe out rival claimants, ordering the deaths of Constantine II's nephews Bemon and Leo, but the boys escaped to Cyprus. Under Mamluk pressure his realm shrank: they seized Ajazzo in 1347, then Tarsus and Adana in 1359, leaving the kingdom little more than Sis.

He married Maria, daughter of Oshin of Corycos. Both his sons died before him, and when he died of natural causes the crown passed to his cousin Constantine IV.
