Lü Guang (Chinese: 呂光; 337–400), courtesy name Shiming (世明), also known by his posthumous name as the Emperor Yiwu of Later Liang (後涼懿武帝), was the founding emperor of the Di-led Chinese Later Liang dynasty (although during most of his reign, he used the title "Heavenly King"). He was initially a Former Qin general, but in light of Former Qin's collapse starting in 384, he decided to found his own state, initially including nearly all of modern Gansu. As his reign continued, however, his domain dwindled after Southern Liang and Northern Liang declared independence. His death in 400 left Later Liang in an unstable state, and it would be no more by 403.
