Het'um II abdicated in favour of his sixteen-year-old nephew Levon III and became a Franciscan friar; however, he emerged from his monastic cell to help Levon defend Cilicia from a Mamluk army, which was thus defeated near Baghras. In 1307, both the current and former kings met with Bularghu, the Mongol representative in Cilicia, at his camp just outside Anazarba. Bularghu, a recent convert to Islam, murdered the entire Armenian party. Oshin, brother of Het'um, immediately marched against Bularghu to retaliate and vanquished him, forcing him to leave Cilicia. Bulargu was executed by Oljeitu for his crime at the request of the Armenians. Oshin was crowned new king of Cilician Armenia upon his return to Tarsus.
