Hethum II, OFM (Armenian: Հեթում Բ; 1266 – November 17, 1307) was king of the Armenian Kingdom of Cilicia from 1289 to 1293, 1295 to 1296 and 1299 to 1303, while Armenia was a subject state of the Mongol Empire. He abdicated twice to take vows with the Franciscans, while still remaining the power behind the throne as "Grand Baron of Armenia" and later as Regent for his nephew.
He was the son of King Leo II of Armenia and Queen Keran, and was part of the Hethumid dynasty, being the grandson of Hethum I, who had originally submitted Cilicia to the Mongols in 1247. Hethum II was assassinated with his nephew and successor Leo III by the Mongol general Bilarghu, who himself was later executed for this by the Mongol Ilkhanid ruler Öljaitü.[1]
