In April 15, 1277, the Mamluk Sultan Baibars marched from Syria into the Mongol-dominated Seljuk Sultanate of Rûm and attacked the Mongol occupation force in the Battle of Elbistan (Abulustayn). Upon reaching Elbistan with at least 10,000 horseman, Baibars made ready for battle with the Mongols, expecting them to be around 30,000. However, although the Mongol forces were smaller than the Mamluk army, they were the Georgians and Rumis who helped bolster their numbers.
