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)
Zhangsun Wuji
Li Yuan captured Chang'an in winter 617 and declared Emperor Yang's grandson Yang You emperor (as Emperor Gong), taking power himself as regent. After he received news in spring 618 that Emperor Yang had been killed at Jiangdu (江都, in modern Yangzhou, Jiangsu) in a coup led by the general Yuwen Huaji, he had Yang You yield the throne to him, establishing Tang Dynasty as its Emperor Gaozu. Li Shimin was created the Prince of Qin and thereafter became the main general in charge of his father's campaigns to reunify China under Tang rule, which was largely complete by 623, when the last major rival to Tang, Liu Heita the Prince of Handong, was captured and killed by Li Shimin's older brother, Li Jiancheng the Crown Prince. For Zhangsun Wuji's contributions to Li Shimin's campaigns, he was created the Duke of Shangdang.
