Constantine of Baberon (died c. 1263) was a powerful Armenian noble of the Het‛umid family. He was the son of Vassag and the father of King Het‛um I, who ruled the Armenian Kingdom of Cilicia from 1226 to 1270. Constantine played a pivotal role in placing his son on the throne by engineering the murder of Philip, the husband of Isabella, Queen of Armenia. He tricked Philip’s father, Bohemond IV of Antioch, to search for his son at Amouda rather than at Sis, where he was being tortured and poisoned. He then took his army to the gates of Silifke Castle, forced its Frankish lords to surrender Isabella, and arranged the marriage, making his son the first Het‛umid ruler of the Armenian Kingdom.
