The County of Tripoli (1109–1289) was the last of the Crusader states. It was founded in the Levant, that is, the modern-day region of Tripoli, northern Lebanon and parts of western Syria which supported an indigenous population of Christians, Druze and Muslims. When the Crusaders, (Christian, mostly Frankish forces), captured the region in 1109, Bertrand of Toulouse became the first Count of Tripoli. He was a vassal of Baldwin I of Jerusalem. From that time, rule of the county was decided not strictly by inheritance but by factors such as military force (external and civil war), favour and negotiation. In 1289, the County of Tripoli fell to Sultan Qalawun of the Muslim Mamluks of Cairo. The county was absorbed into Mamluk Egypt.
