Taizu of Liao, Khitan ruler (b. 872)
Abaoji (872 – 6 September 926), posthumously known by his temple name as the Emperor Taizu of Liao, was a Khitan leader and the founding emperor of the Liao dynasty of China, ruling from 916 to 926. He had a sinicised name, Yelü Yi; some sources suggest that Abaoji's family name, Yelü, was adopted during his lifetime, although there is no unanimity on this point.
Abaoji was born in 872 in Southern Mongolia and had a turbulent childhood. His grandfather was killed in a conflict between tribes, and his father and uncles fled. He was hidden by his grandmother for his safety. He became khagan of the Khitans on 27 February 907, and was subsequently enthroned as emperor in 916, proclaiming his own era name. He died on 6 September 926. He was responsible for the conquest and unification of all of Inner Mongolia, northern China and southern Manchuria. Once the Khitan Empire became the Liao dynasty in 942, he was posthumously considered a Liao emperor.
