The Principality of Antioch, including parts of modern-day Turkey and Syria, was one of the crusader states created during the First Crusade.While Baldwin of Boulogne and Tancred headed east from Asia Minor to set up the County of Edessa, the main army of the First Crusade continued south to besiege Antioch. Bohemond of Taranto led the siege, beginning in October, 1097. With over four hundred towers, the city was almost impenetrable. The siege lasted throughout the winter, with much suffering among the Crusaders, who were often forced to eat their own horses, or, as legend has it, the bodies of their fellow Christians who had not survived.
