 Complete the following phrase:  After Baghdad, in 1260 the Mongols with their Christian subjects conquered Muslim Syria, domain of the Ayyubid dynasty. They took together the city of Aleppo in January, and in March, the Mongols with the Armenians and the Franks of Antioch took Damascus, under the Christian Mongol general Kitbuqa. With both the Abbasid and Ayyubid dynasties destroyed, the Near East, as described by historian Steven Runciman, was never again to dominate civilization. The last Ayyubid sultan An-Nasir Yusuf died shortly thereafter, and with the Islamic power centers of Baghdad and Damascus gone, the center of Islamic power transferred to the Egyptian Mamluks in Cairo. However, before the Mongols could continue their advance towards Egypt, they needed to withdraw because of the death of the Great Khan. Hulagu was needed back at the capital and took the bulk of his forces with him, leaving a small force under Kitbuqa to occupy Palestine during his absence.
