The County of Tripoli (1109–1289) was the last Crusader state founded in the Levant, located in what today are parts of western Syria and northern Lebanon, where exists the modern city of Tripoli. The Crusader state was captured and created by Christian forces in 1109, originally held by Bertrand of Toulouse as a vassal of Baldwin I of Jerusalem. The County of Tripoli later became a substate of the Principality of Antioch in the 13th century. In the mid-13th century, its leader Bohemond VI, under the influence of his father-in-law Hetoum I of Cilician Armenia, swore vassalage to the Mongol Empire, and contributed troops to the Mongol conquests in the region.
In retaliation, the Sultan Qalawun, of the Muslim Mamluks in Cairo, attacked and destroyed both Tripoli and Antioch, absorbing the territories back into the Islamic Empire in the late 13th century. The Fall of Tripoli took place in 1289.
