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)
Administrative divisions of the Tang dynasty
Some 20 years after Emperor Wuzong's death, the Tang empire began its last phase of collapse. The source of the downfall can be traced to an event in 868 when a group of soldiers in Gui Prefecture (Guangxi) under Pang Xun rebelled after the government ordered them to extend their garrison duty for one extra year, even though they had already served six years on what was supposed to be a three-year assignment. The rebellion spread northwards to the Chang Jiang and Huai River before its suppression in 869 by Shatuo cavalry under the command of Li Guochang. While the Tang court was still smarting from the impact of the Pang Xun rebellion, in 874, a salt trader by the name of Wang Xianzhi stirred up another rebellion in Changyuan, Puzhou, Henan. In 875 Wang was joined by Huang Chao, who eventually took over leadership of the rebel army when Wang died in 878. The cataclysmic Huang Chao rebellion was one of such vast magnitude that it shook the very foundations of the Tang empire, destroying it both internally as well as cutting off any pre-existing foreign contacts it had with the outside world. At the rebellion's peak, Huang claimed to command an army of one million. It swept through much of the lower and middle Yangzi valleys, devastated the Central Plains, and went as far south as Guangzhou (879). After sacking the twin capitals Luoyang in 880 and Chang'an the following year, Huang Chao declared the founding of his Great Qí (大齊) dynasty.
