Battle of Ain Jalut
The last recorded appearance of the Crusaders in Hauran was in 1217. The Ayyubids had conquered the region in the late 12th century, but their rule collapsed in Syria following the Mongol invasion in 1260. That year the Mongols were defeated by the Mamluks at the Battle of Ain Jalut and Syria, including the Hauran, came under Mamluk rule.
