Oshin of Armenia

Oshin (1282–1320), a son of Leo II of Armenia, seized the Cilician crown after the Mongol Bilarghu murdered his brother Hethum II and nephew Leo III in November 1307. He defeated Bilarghu and drove him out, while the Ilkhan Öljeitü confirmed his kingship and had the killer executed.

His pro-Roman church-union policy stirred discontent. By Isabel of Korikos he had Leo IV, and in 1316 married Joan of Taranto. He died on 20 July 1320, widely believed poisoned by Oshin of Corycos.
