Bohemond was the natural leader of the crusading host but, through a trick, he took Antioch and did not continue on to Jerusalem with the rest of the army, instead remaining in the newly conquered city to carve out a principality for himself there. Tancred also left the main Crusade at Heraclea Cybistra to fight for territory in Cilicia. A great state like the one his cousins were forging in Europe, however, was impossible for Bohemond. He was defeated badly at the Battle of Harran and forced later to sign the Treaty of Devol with Byzantium. Nevertheless, his son Bohemond II inherited the Crusader state. He in turn gave it to his only daughter, Constance, who ruled it until 1163.
