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)
Foreign relations of imperial China
Although the reign of Emperor Xuanzong (r. 712–756) is seen as the zenith point of the Tang dynasty, it was during the last years of his reign that one of the most destructive rebellions in Chinese history occurred. The Tang Empire had recruited many Central Asian Turks into their armed forces. One of these was An Lushan (703–757), a Sogdian-Turk who became a military commander and personal favorite of Emperor Xuanzong's concubine Consort Yang. He instigated the An Lushan Rebellion, which caused the deaths of millions of people, cost the Tang dynasty their Central Asian possessions, and allowed the Tibetans to invade China and temporarily occupy the capital, Chang'an. The Tang dynasty recovered under Emperor Xianzong (805-820) but it never achieved its former martial and political strength. The unintended effect of the rebellion, however, was the loosening of government restrictions on trade. Although the 9th century was politically turbulent, the economy of China actually continued to thrive, bolstered still by foreign trade. The Japanese were sending embassies to the Tang Empire as late as 894, which was finally halted by Emperor Uda by the persuasion of Sugawara no Michizane.
