Liao Dynasty

The Liao Dynasty (simplified Chinese: 辽朝; traditional Chinese: 遼朝; pinyin: Liáo Cháo; Khitan language: Mos Jælud), also known as the Khitan Empire (simplified Chinese: 契丹国; traditional Chinese: 契丹國; pinyin: Qìdān Guó; Khitan: Mos diau-d kitai huldʒi gur), was an empire in East Asia that ruled over Mongolia and portions of the Russian Far East and northern China proper from 907 to 1125. It was founded by the Khitan Great Khan Abaoji around the time of the collapse of the Han Chinese Tang Dynasty.

The Liao Empire was destroyed by the Jurchen people of the Jin Dynasty in 1125. However, remnants of its people, led by Yelü Dashi, established the Western Liao Dynasty, also known as the Kara-Khitan Khanate, which ruled over parts of Central Asia for almost a century before being conquered by Genghis Khan's Mongolian army.
