Southern Liang
In 397, after Lü Guang had suffered a loss on the battlefield against Western Qin's prince Qifu Gangui, Tufa Wugu declared himself the Prince of Xiping and changed era name, signifying a declaration of independence for Southern Liang. He then captured Later Liang's city Jincheng (金城, in modern Lanzhou, Gansu), which Later Liang had only captured from Western Qin earlier that year. Lü Guang sent his general Dou Gou (竇苟) to attack Southern Liang, but was defeated by Tufa Wugu.
