The Liao dynasty fell in 1125. Some Khitans fled west under the leadership of Yelü Dashi after their defeat by the Jurchens and founded the Western Liao dynasty (1124–1218) in present-day Xinjiang and eastern Kazakhstan with capital in Balasagun, modern Kyrgyzstan. In addition, the Western Liao also controlled some highly autonomous vassalized states, such as Khwarezm, the Eastern and the Western Kara-Khanids, etc. In 1218, Genghis Khan destroyed the Western Liao, after which the Khitans passed into obscurity. The modern-day minority of Mongolic-speaking Daurs in China are their direct descendants based on DNA evidence and other Khitans assimilated into the Mongols (Southern Mongols), Turkic peoples and Han Chinese.
