The Emperor Taizu of Liao (辽太祖) was the first emperor of the Liao Dynasty (907-926). His given name was Abaoji (阿保机). Some sources also suggest that the surname Yelü (耶律) was adopted during his lifetime, though there is no unanimity on this point.

He was born in 872 and died in 926 in China. He had a turbulent childhood. His grandfather was killed in a conflict between tribes, and his father and uncles fled. Yelü Abaoji was hidden by his grandmother for his safety.
