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.
Tang poetry
After the official fall of the Tang dynasty in 907, some members of its ruling house of Li managed to find refuge in the south of China, where their descendants founded the Southern Tang dynasty in the year 937. This dynasty continued many of the traditions of the former great Tang dynasty, including poetry, until its official fall in 975, when its ruler, Li Yu, was taken into captivity. Importantly for the history of poetry, Li survived another three years as a prisoner of the Song dynasty, and during this time composed some of his best known works. Thus, including this "afterglow of the T'ang dynasty", the final date for the Tang Poetry era can be considered to be at the death of Li Yu, in 978.
