楚王
In 907, Zhu Quanzhong had Emperor Zhaozong's son and successor Emperor Ai yield the throne to him, ending Tang and establishing a new Later Liang as its Emperor Taizu. Several Tang warlords, including Yang Wo, Li Maozhen, Li Keyong, and Wang Jian, refused to recognize him as emperor, but the rest of the formerly Tang realm did, including Ma Yin's Wu'an Circuit. Shortly thereafter, the new Later Liang emperor created Ma the Prince of Chu. Emperor Taizu also gave him the title of military governor of Wuchang, even though he did not control Wuchang.
