Liu Shi , courtesy nameZishao, was a chancellor of the Chinese dynastyTang Dynasty, during the reign of Emperor Gaozong. His niece was Emperor Gaozong's first wife Empress Wang, and as Emperor Gaozong's favors for her waned, Liu found himself in a precarious position. in 654, he resigned his chancellor post, but was not able to escape being exiled in 655 when Empress Wang was deposed and killed, in favor of Empress Wu. In 659, as part of a campaign of Empress Wu's attempt to take vengeance on anyone who opposed her ascension, Emperor Gaozong issued an edict to have Liu executed.
Background
It is not known when Liu Shi was born. His family was from Pu Prefecture. His father Liu Ze had served as an imperial guard commander during Sui Dynasty and died while serving as an emissary to Goguryeo. It was said that Liu Shi went to Goguryeo to retrieve his father's body, and his mournfulness impressed the people of Goguryeo. His uncle Liu Heng served as an official under Tang Dynasty's first three emperors, Emperor Gaozu, Emperor Taizong, and Emperor Gaozong. Not much, however, was recorded about Liu Shi's career prior to 651.
During Emperor Gaozong's reign
In 651, Emperor Gaozong, whose wife Empress Wang was a niece of Liu Shi's, gave Liu Shi, who was then serving as Zhongshu Shilang -- the deputy head of the legislative bureau of government -- the additional designation of Tong Zhongshu Menxia Sanpin, making him a chancellor de facto. In 652, Emperor Gaozong further promoted him to the post of Zhongshu Ling -- the head of the legislative bureau and a post considered one for a chancellor. Empress Wang was sonless, and Liu suggested to her that she should request that Emperor Gaozong's oldest son, Li Zhong, whose mother Consort Liu was of low birth, be created crown prince, so that Li Zhong would be grateful to her. Empress Wang did so, and Emperor Gaozong agreed, after Liu Shi lobbied his fellow chancellors, including Emperor Gaozong's powerful uncle Zhangsun Wuji. Later in 652, Emperor Gaozong created Li Zhong crown prince. By 654, however, Emperor Gaozong's favors for Empress Wang had waned, particularly in light of his increasing favor for his concubineConsort Wu. The situation was exacerbated by the fact that Empress Wang was not good at earning the loyalty of the other concubines and the ladies in waiting, while Consort Wu was able to, and also that Liu Shi and his sister and Empress Wang's mother Lady Liu were not respectful to the other concubines. In 654, in fear, Liu requested to be relieved of his chancellor post, and Emperor Gaozong agreed, making him the minister of civil service, no longer a chancellor. In 655, Consort Wu falsely accused Empress Wang and Lady Liu of using witchcraft to try to regain favor for Empress Wang. In response, Emperor Gaozong barred Lady Liu from the palace and demoted Liu out of the capital Chang'an to be the prefect of Sui Prefecture. As he travelled through Qi Prefecture, the prefectural secretary general Yu Chengsu submitted a report accusing Liu of revealing palace secrets, and Emperor Gaozong further demoted Liu to be the prefect of Rong Prefecture, a smaller prefecture. Later that year, Emperor Gaozong deposed Empress Wang and replaced her with Consort Wu, and the former Empress Wang was soon executed along with her ally Consort Xiao by order of the new Empress Wu. In 657, Empress Wu's allies Xu Jingzong and Li Yifu further accused the chancellors Han Yuan and Lai Ji, both of whom had opposed Empress Wang's removal and Empress Wu's ascension, of conspiring with the former chancellor Chu Suiliang, who was even more vocal in his opposition and who had been demoted as a result. Han, Lai, and Chu were all demoted to be prefects of distant prefectures, and Liu was also further demoted to be the prefect of the extremely distant Xiang Prefecture. In 659, Empress Wu carried out even more reprisals—this time, having Xu falsely accuse Zhangsun, who had shown implicit disapproval of her ascension, of treason, and Chu, Liu, and Han of encouraging Zhangsun. Zhangsun was exiled, while Liu and Han were demoted to commoner rank. In fall 659, Emperor Gaozong further sent imperial messengers to arrest Liu and Han, as well as Zhangsun Wuji's cousin Zhangsun En, but even while imperial messengers were on the way changed the order to have Liu and Han executed instead. Liu's clan members were exiled to the modern Guangdong and Guangxi region, while his immediately family was specifically confiscated to become servants at Gui Prefecture.
After death
After Emperor Gaozong's death around the new year 684, Empress Wu seized power and eventually declared herself "emperor" in 690. After Empress Wu's own removal in 705 by her son Emperor Zhongzong, Liu Shi's offices were posthumously restored, and after her death that year, the exile order against Liu's clan members was cancelled. Early in the Kaiyuan era of Emperor Zhongzong's nephew Emperor Xuanzong, Liu Shi's grandnephew Liu Huan was serving as a mid-level official at the legislative bureau, when he submitted a position pointing out that Liu was wrongly executed and that, while his reputation had been restored, he was still buried a long distance from the capital and that his only surviving descendant, his great-grandson Liu Wutian, remained in exile. Emperor Xuanzong issued an edict approving Liu Shi's reburial at his home prefecture Pu Prefecture, and had Liu Wutian escort Liu Shi's casket there. Liu Wutian later served in the imperial administration as the commandant of Tan Prefecture.
