From 1149, all Fatimid caliphs were children, and military commanders were competing for power. Ascalon, the Fatimids' last Palestinian bridgehead, hindered Frankish raids against Egypt, but Baldwin captured the town in 1153. The Damascenes feared further Frankish expansion, and Nur ad-Din seized the city with ease a year later. He continued to remit the tribute that Damascus' former rulers had offered to the Jerusalemite kings. Baldwin extracted tribute from the Egyptians as well. Raynald lacked financial resources. He tortured the Latin Patriarch of Antioch, Aimery of Limoges, to appropriate his wealth and attacked the Byzantine's Cilician Armenians. When Emperor Manuel I Komnenos delayed the payment he had been promised, Raynald pillaged Byzantine Cyprus. Thierry, Count of Flanders, brought military strength from the West for campaigning. Thierry, Baldwin, Raynald and Raymond III of Tripoli attacked Shaizar. Baldwin offered the city to Thierry, who refused Raynald's demands he become his vassal, and the siege was abandoned. After Nur ad-Din seized Shaizar in 1157, the Nizari remained the last independent Muslim power in Syria. As prospects for a new crusade from the West were poor, the Franks of Jerusalem sought a marriage alliance with the Byzantines. Baldwin married Manuel's niece, Theodora, and received a significant dowry. With his consent, Manuel forced Raynald into accepting Byzantine overlordship.
