orig. Marc
born 1050–58
died March 5 or 7, 1109, probably Bari
Prince of Otranto (1089–1109) and of Antioch (1098–1101, 1103–4).
The son of a duke who held sway in southeastern Italy, he was nicknamed after a legendary giant. He joined his father's army and contested with Alexius I Comnenus for territory in the Byzantine Empire. In 1095 he joined the First Crusade , reconquering Byzantine lands from the Turks and capturing Antioch (1098). Rather than taking part in the battle to gain Jerusalem, Bohemond remained in Antioch, which he ruled as a principality. His efforts to muster French and Italian support against Alexius and the Byzantine Empire were ultimately unsuccessful.
