トリポリ伯国
Bohemond was installed as prince after his mother was dethroned. Nur ad-Din laid siege to Krak des Chevaliers in the County of Tripoli in September 1163. Raymond III of Tripoli appealed to Bohemond for assistance. Bohemond and Constantine Kalamanos, Byzantine governor of Cilicia, hurried to the castle. The united Christian armies defeated the besiegers in the Battle of al-Buqaia.
