the Ayyubid sultan, Saladin (r. 1174–1193), along with the Minaret of the Bride, which had been destroyed in the 1069 fire. During the internal feuds between later Ayyubid princes, the city was dealt a great deal of damage, and the mosque's eastern minaret—known as the 'Minaret of Jesus'—was destroyed at the hands of as-Salih Ayyub of Egypt while besieging as-Salih Ismail of Damascus in 1245. The minaret was later rebuilt with little decoration. Saladin, along with many of his successors, were buried around the Umayyad Mosque (see Mausoleum of Saladin). Mamluk era The Mongols, under the leadership of the Nestorian Christian Kitbuqa, with the help of some submitted Western Christian forces, captured Damascus from the Ayyubids in 1260 while Kitbuqa's superior Hulagu Khan had returned to the Mongol Empire for other business. Bohemond VI of Antioch, one of the Western Christian generals in the invasion, ordered Catholic Mass to be performed in the Umayyad Mosque. However, the Muslim Mamluks of Egypt, led by Sultan Qutuz and Baibars, wrested control of the city from the Mongols later in the same year, killing Kitbuqa in the Battle of Ain Jalut, and the purpose of the Mosque was returned from Christian to its original Islamic function. In 1270, Baibars, by now sultan, ordered extensive restorations to the mosque, particularly its marble, mosaics and gildings. According to Baibars' biographer, Ibn Shaddad, the restorations cost the sultan 20,000 dinars. Among the largest mosaic fragments restored was a segment in the western portico called the "Barada panel". The mosaics that decorated the mosque were a specific target of the restoration project and they had a major influence on Mamluk architecture in Syria and Egypt. In 1285, the Hanbali scholar Ibn Taymiyyah started teaching Qur'an exegesis in the mosque. When the Ilkhanid Mongols under Ghazan invaded the city in 1300, Ibn Taymiyya preached jihad, urging the citizens of Damascus to resist their occupation. The Mamluks under Sultan Qalawun drove out the Mongols later that year. When Qalawun's forces entered the city, the Mongols attempted to station several catapults in the Umayyad Mosque because the Mamluks had started fires around the citadel to prevent Mongol access to it. The attempt failed as the Mamluks proceeded to burn the catapults before they were placed in the mosque. The Mamluk viceroy of Syria, Tankiz, carried out restoration work in the mosque in 1326–1328. He reassembled the mosaics on the qibla
