Isabella I of Armenia

Isabella, also called Zabel (c. 1216–1252), was queen regnant of Armenian Cilicia from 1219 until her death. Only child of Leo I and Sibylla of Cyprus, she succeeded at about three; the rival Raymond-Roupen was defeated and executed. Her regent Adam of Baghras was assassinated and Constantine of Baberon became her guardian.

Constantine married her to Philip of Antioch in 1222, but Philip plundered the palace and was poisoned at Sis. Constantine then forced her to marry his son Hethum I, who ruled with her and founded the Hethumid dynasty. She died on 23 January 1252.
