Bohemund III of Antioch

Bohemund III was the son of Constance of Antioch by her first husband Raymond of Poitiers. His second wife was Orguilleuse, whom he had two sons: Raymond, the father of Raymond-Roupen of Antioch and Bohemund IV of Antioch. In 1180, Bohemund abandoned his lawful wife to join a woman name Sybilla and, in consequence, was excommunicated by Pope Alexander III. His sister Maria of Antioch married Byzantine emperor Manuel I Comnenus.
