Yelü

The Yelü clan established numerous dynastic regimes in Chinese history: the Liao dynasty, Northern Liao, Western Liao, Eastern Liao, and Later Liao. In particular, the Liao dynasty and Western Liao were powerful empires that had significant impact on regional history.

Rise to power

Abaoji, born in 872, was the son of the chieftain of the Yila tribe. At this time, the Yaolian clan had led the Khitan people since the mid-eighth century, and were the only Khitan family to have adopted a surname at this point as this was seen as a mark of Han culture and not befitting of peoples of the steppe.

In 901, Abaoji was elected chieftain of the Yila tribe and in 905 forged relations with Li Keyong of the Shatuo Turks. In 907, he was chosen leader of the Khitans, the first outside the Yaolian lineage to be chosen in more than a century and a half. From this, Abaoji and his successors developed the Liao dynasty, which would conquer all of Manchuria, the northern fringe of the Central Plain known as the Sixteen Prefectures and adjacent areas of northern Korea, eastern Mongolian Plateau and parts of far-eastern Siberia.
