Yelü Bei
Yelü Bei () (899 – January 7, 937), also known as Yelü Tuyu (耶律突欲 or 耶律圖欲), posthumously honored Wenxian Qinyi Huangdi () with the temple name Yizong (Simplified: 辽义宗, Traditional: 遼義宗), formally known as Ren Huangwang (人皇王, "imperial king of men") during his lifetime (including his period as the King of Dongdan), known as Dongdan Muhua () (931) and then Li Zanhua () (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 (Emperor Taizong), he fled to the Shatuo-led Later Tang, where he was killed in 937.
