A string of Mongol victories, starting in 1218 when they invaded Khwarezm, quickly gave the Mongols control over Persia as well as the Seljuk Sultanate of Rum of Asia Minor. Incorporated troops from submitted countries such as Cilician Armenia and the Kingdom of Georgia, in 1258, the Mongols sacked Baghdad followed in 1260 by the taking of Aleppo and Damascus. Later that same year, the Mongols experienced their first major defeat at the Battle of Ain Jalut, which eventually forced the Mongols out of Damascus and Aleppo and back across the Euphrates.
