Constantine II[1] (Armenian: Կոստանդին Բ), also Kostandin II,[citation needed] (unknown[citation needed] – after February 17, 1129[citation needed]) was the fourth lord of Armenian Cilicia[2] (1129[citation needed]/1130[1]).
The Chronique Rimée de la Petite Arménie (“The Rhymed Chronicle of Armenia Minor”) of Vahram of Edessa records that he was the son of Thoros I, lord of Armenian Cilicia.
[citation needed] His mother's name is not known.
[citation needed] He and his father's deaths occurred during 1129.
[1] After the death of Thoros, his only son and heir was cast into prison by some wicked people, who administered to him a poisonous drug, thus the principality came to Leon, the brother of Thoros (…).Other historians (e.g., Jacob G. Ghazarian, Vahan M. Kurkjian) suggest that there were no successors for Toros.
