Kara-Khitan Khanate
The Kara-Khitan or Qara-Khitai Khanate (Mongolian: Хар Хятан; Persian: خانات قراختایی), also known as Western Liao (simplified Chinese: 西辽; traditional Chinese: 西遼; pinyin: Xī Liáo) (1124-1218) was a Khitan empire in Central Asia. The dynasty was founded by Yelü Dashi, who led the remnants of the Liao Dynasty to Central Asia after fleeing from the Jurchen conquest of their homeland in North and Northeast of modern day China. The empire was usurped by the Naimans under Kuchlug in 1211; traditional Chinese, Persian and Arab sources considered the usurpation to be the end of the Kara-Khitan rule. The empire was later taken by the Mongol Empire in 1218.
