Emperor Ai of Tang
The new Later Liang emperor created Li Chu the Prince of Jiyin and moved him from Luoyang to Cao Prefecture (曹州, in modern Heze, Shandong), and put his mansion under heavy guard, with a fence of thorns surrounding it. In 908, he had Li Chu poisoned to death, and gave Li Chu the posthumous name of "Ai" (哀, "lamentable"). In 928, by which time Li Keyong's adoptive son Li Siyuan was ruling as the emperor of Jin's successor state Later Tang (as Emperor Mingzong), which claimed to be the legitimate continuation of Tang Dynasty and which had earlier destroyed Later Liang, Emperor Mingzong's officials suggested that a temple be built to honor Emperor Ai. Emperor Mingzong had such a temple built at Cao Prefecture. In 929, Emperor Mingzong's officials further suggested giving Emperor Ai a more proper (i.e., more Tang-traditional) posthumous name of Emperor Zhaoxuan Guanglie Xiao, with a temple name of Jingzong, but they also pointed out that since Emperor Ai's temple was not among the imperial ancestral temples, a temple name was not proper. Therefore, only the new posthumous name was adopted, and the temple name was not. Traditional histories thus referred to him mostly as Emperor Ai but also at times as Emperor Zhaoxuan.No family recorded in official histories; Song dynasty general Li Gang was claimed to be a descendant through a son named Li Xizhao (李熙照)
Military history of the Sui–Tang dynasties
The Tang Empire collapsed into numerous rival warlord states, ushering in the period of Five Dynasties and Ten Kingdoms. In the south emerged the kingdoms of Wuyue, Min, and Southern Han. In the north, Li Keyong of Hedong and Zhu Quanzhong of Bianzhou vied for supremacy. Zhu held the last two Tang emperors as captives and controlled the North China Plain. He made an unsuccessful attempt to murder Li in 884 and proclaimed himself Emperor of Later Liang in 907. Zhu's Liang dynasty survived for only 11 years after his death in 912, and it was conquered in 923 by Li Keyong's successor Li Cunxu, founder of Later Tang. In 937, the Later Tang gave way to a number of short lived military regimes from which the Song dynasty eventually emerged, reuniting most of China by 979. However the Song never quite achieved the hegemonic status of the early Tang. It was, militarily speaking, at best only equal and at worst completely inferior to its northern neighbor, the Khitan Liao dynasty, followed by the Jurchen Jin dynasty.
