Imad ad-Din Zengi
Pons closely cooperated with Tancred's successor, Roger of Salerno, against the Muslim rulers in the 1110s. He refused obedience to Baldwin II of Jerusalem in early 1122, but their vassals soon mediated a reconciliation between the two rulers. Pons was one of the supreme commanders of the crusader troops during the successful siege of Tyre in 1124. He supported Alice of Jerusalem, the dowager princess of Antioch, against her brother-in-law, Fulk, King of Jerusalem, in late 1132, but they could not prevent him from taking control of Antioch. A year later, Pons was only able to defend his county against Imad ad-Din Zengi, atabeg of Mosul, with Fulk's assistance.
