Lü Long

Lü Long (; died 416), courtesy name Yongji (永基), was the last ruler of the Di-led Chinese Later Liang dynasty. He was the nephew of the founding emperor Lü Guang (Emperor Yiwu), and he took the throne after his brother Lü Chao (呂超) assassinated the emperor Lü Zuan (Emperor Ling) in 401 and offered the throne to him. During his reign, Later Liang was under constant attacks by Northern Liang and Southern Liang and reduced largely to its capital Guzang (姑臧, in modern Wuwei, Gansu). In 403, Lü Long decided to end the state by surrendering Guzang to Later Qin's emperor Yao Xing. He became a Later Qin official, but after aligning himself with Yao Xing's son Yao Bi (姚弼), who made unsuccessful attempts to seize the crown prince position from Yao Hong, was executed by Yao Hong after Yao Xing's death in 416.
