Pons was count of Tripoli from 1112 to 1137. He was a minor when his father, Bertrand, died in 1112. He swore fealty to the Byzantine Emperor Alexios I Komnenos in the presence of a Byzantine embassy. His advisors sent him to Antioch to be educated in the court of Tancred of Antioch, ending the hostilities between the two crusader states. Tancred granted four important fortresses to Pons in the Principality of Antioch. Since Pons held his inherited lands in fief of the kings of Jerusalem, Tancred's grant strengthened the autonomy of the County of Tripoli. On his deathbed, Tancred also arranged the marriage of his wife, Cecile of France, to Pons.

The County of Tripoli (1102–1289) was one of the Crusader states. It was founded in the Levant in the modern-day region of Tripoli, northern Lebanon and parts of western Syria. When the Frankish Crusaders – mostly southern French forces – captured the region in 1109, Bertrand of Toulouse became the first count of Tripoli as a vassal of King Baldwin I of Jerusalem. From that time, the rule of the county was decided not strictly by inheritance but by factors such as military force, 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.
