Yelü Bei

Yelü Bei, also known as Yelü Tuyu, posthumously honored Wenxian Qinyi Huangdi (文獻欽義皇帝) with the temple name Yizong, formally known as Ren Huangwang during his lifetime, known as Dongdan Muhua (東丹慕華) (931) and then Li Zanhua (李贊華) (931-937) as a Later Tang subject, was the eldest son of Emperor Taizu of Liao, the founder of the Liao dynasty. He was declared successor to the Emperor Taizu in 916, but never succeeded to the throne. Rather, after the accession of his younger brother Yelü Deguang, he fled to the Shatuo-led Later Tang, where he was killed in 937.
