معركة عين جالوت
The Mongol expansion into the Middle East was stopped in 1260, when the Franks in Acre struck a passive alliance with the Egyptian Mamluks, allowing the Muslim Mamluks to achieve a decisive victory against the Mongols at the pivotal Battle of Ain Jalut, a battle in which 500 knights from Armenia may have participated, fighting on the side of the Mongols.
