Life

The Linya Heads West

Yelü Dashi was an eighth-generation descendant of Emperor Taizu of Liao. Versed in both Khitan and Chinese, he passed the jinshi examination and rose to Hanlin Academician; since the Khitan called a Hanlin scholar "linya," he was known as "Dashi Linya." When the Jin attacked the Liao in 1122, he enthroned Yelü Chun at Yanjing and resisted both the Jin army and the Northern Song army.

Founding Western Liao

In 1124, after a disagreement with Emperor Tianzuo, he left with some 200 horsemen, pushed north to Kedun, rallied seven prefectures and 18 tribes of the Northern Gobi, and reorganized his army to march west. He founded a city at Emil in Central Asia and in 1132 proclaimed himself emperor with the title "Gurkhan," founding what historians call Western Liao.

Battle of Qatwan

In 1141 he routed the coalition of the Seljuk sultan Sanjar at the Battle of Qatwan, taking control of Transoxiana. Western Liao ruled Central Asia for nearly 80 years, carrying the name "Khitan" (Qara Khitai) far to the West. He died in 1143.

Legacy

After the Fall of Liao, Yelü Dashi founded the Western Liao, which ruled Central Asia for nearly 80 years; he is thought to be one of the sources of the European legend of Prester John.
