Constantine of Baberon

Constantine of Baberon (died c. 1263), called the Grand Baron, was a powerful noble of the Hethumid house in Cilician Armenia. As guardian of Queen Isabella, he engineered the murder in 1226 of her husband, Philip of Antioch.

He tricked Philip's father Bohemond IV into looking for his son at Amouda while Philip was held at Sis, then forced the Frankish garrison at Silifke to surrender the queen and married her to his own son Hethum I, founding the Hethumid royal line. By his third wife Biatr he fathered Constantine, lord of Neghir, ancestor of later Armenian kings.
