Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
Southern Tang
The last ruler, Li Yu (Li Houzhu), took over the state upon the death of his father in 961. The Song dynasty had conquered the northern part of the state located in Huainan, and thus Li Yu reigned no longer as an emperor but as the Ruler of the State of Jiangnan (Jiangnan guozhu 江南國主). Li Yu managed to maintain a semi-independent status of vassal of the Song but had to finally surrender after fighting for almost a year in 975. He was taken to the Song capital in Kaifeng where he offered his formal surrender to the Song emperor in early 976.
