In 907, Zhu Quanzhong had Tang's final emperor Emperor Ai yield the throne to him, ending Tang and starting a new Later Liang with him as its Emperor Taizu. Li Keyong and several other regional governors (Yang Wo the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu), Li Maozhen the military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi), and Wang Jian the military governor of Xichuan Circuit) refused to recognize the new Later Liang emperor, with Li Keyong, Li Maozhen, and Yang continuing to maintain the Tang era name of "Tianyou", while Wang shortly after declared himself the emperor of a new state of Former Shu, although Li Keyong was effectively the ruler of his own state of Jin as he carried the title of Prince of Jin. In 908, Li Keyong died and was succeeded as the Prince of Jin by his son Li Cunxu.
