Ayyubid rule (and independence) came to an end with the Mongol invasion of Syria in 1260, in which the Mongols led by Kitbuqa entered the city on 1 March 1260, along with the King of Armenia, Hethum I, and the Prince of Antioch, Bohemond VI; hence, the citizens of Damascus saw for the first time for six centuries three Christian potentates ride in triumph through their streets. However, following the Mongol defeat at Ain Jalut on 3 September 1260, Damascus was captured five days later and became the provincial capital of the Mamluk Sultanate, ruled from Egypt, following the Mongol withdrawal. Following their victory at the Battle of Wadi al-Khaznadar, the Mongols led by Ghazan besieged the city for ten days, which surrendered between December 30, 1299, and January 6, 1300, though its Citadel resisted. Ghazan then retreated with most of his forces in February, probably because the Mongol horses needed fodder, and left behind about 10,000 horsemen under the Mongol general Mulay. Around March 1300, Mulay returned with his horsemen to Damascus, then followed Ghazan back across the Euphrates. In May 1300, the Egyptian Mamluks returned from Egypt and reclaimed the entire area without a battle. In April 1303, the Mamluks managed to defeat the Mongol army led by Kutlushah and Mulay along with their Armenian allies at the Battle of Marj al-Saffar, to put an end to Mongol invasions of the Levant. Later on, the Black Death of 1348–1349 killed as much as half of the city's population.
