Yelü Dashi
The principality was significantly weakened by the early 12th century and the territory of modern Kyrgyzstan was conquered by the Mongolic Khitan people. The Kara-Khitan Khanate (Traditional Chinese: 西遼; Simplified Chinese: 西辽; pinyin: Xī Liáo, 1124–1218), also known as Western Liao, was established by Yelü Dashi (耶律大石) who led around 100,000 Khitan remnants after escaping the Jurchen conquest of their native country, the Khitan dynasty.
