Battle of Ain Jalut
In 1260, the Mamluks advanced from Egypt, being allowed to camp and resupply near the Christian stronghold of Acre, and engaged Kitbuqa's forces just north of Galilee at the Battle of Ain Jalut. The Mongols were defeated, and Kitbuqa executed. This pivotal battle marked the western limit for Mongol expansion in the Middle East, and the Mongols were never again able to make serious military advances farther than Syria.
