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)
Tang campaign against Kucha
After 649, the Tang Dynasty continued their war against the Western Turks under the reign of Emperor Gaozong, Taizong's successor. Gaozong conducted a campaign led by general Su Dingfang against the Western Turk qaghan, Ashina Helu in 657. The qaghan surrendered, the Western Turks were defeated, and the khaganate's former territories were annexed by the Tang. The Tang retreated from beyond the Pamir Mountains in modern Tajikistan and Afghanistan after a Turkic revolt in 662, and lost the Tarim Basin to local revolts and Tibetan incursions in 665-670. The Tang regained the Tarim Basin in 692 and again lost it to the Tibetans in the 790s, the Four Garrisons having already been cut off from the rest of the Tang empire by a Tibetan conquest of the Gansu Corridor. Although the Tibetan empire collapsed in the middle of the ninth century, the Tang Dynasty lacked the means to regain dominance in the Tarim Basin and itself ended in 907 with the abdication of Emperor Ai.
