The Liao dynasty was destroyed by the Jurchen-led Jin dynasty in 1125 with the capture of Emperor Tianzuo of Liao. However, the remnant Khitans, led by Yelü Dashi (Emperor Dezong of Liao), established the Western Liao dynasty (Qara Khitai), which ruled over parts of Central Asia for almost a century before being conquered by the Mongols. Although cultural achievements associated with the Liao dynasty are considerable, and a number of various statuary and other artifacts exist in museums and other collections, major questions remain over the exact nature and extent of the influence of the Liao Khitan culture upon subsequent developments, such as the musical and theatrical arts.
