Prince of Hongnong
In 907, Zhu Quanzhong had Emperor Zhaozong's son and successor Emperor Ai yield the throne to him, ending Tang Dynasty and starting a new Later Liang with him as its Emperor Taizu. A number of regional warlords refused to recognize him as their emperor and whose domains effectively became independent states — including Li Maozhen (whose state became known as Qi as his title was Prince of Qi), Li Keyong the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) (whose state became known as Jin as his title was Prince of Jin), Yang Wo the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu) (whose title was Prince of Hongnong but whose state was also known as Wu as his father and predecessor Yang Xingmi was the Prince of Wu) and Wang Jian (whose state became known as Former Shu as his title was Prince of Shu and he soon thereafter claimed the title of emperor himself).
