Bohemund III of Antioch (1144-1201), also know as the Stammerer, was ruler of the principality of Antioch (a crusader state) from 1163 to his death.
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.
