Lai Ji was an official of the Chinese dynastyTang Dynasty, serving as a chancellor during the reign of Emperor Gaozong. He later offended Emperor Gaozong by opposing the ascension of Emperor Gaozong's second wife Empress Wu and was exiled to be a prefect in the extreme western part of the state. In 662, he died in battle while defending his prefecture against a Western Tujue attack. His brother Lai Heng also served as a chancellor during Emperor Gaozong's reign.
Early life
Lai Ji's family was from Jiangdu. His father Lai Hu'er was a major general during Sui Dynasty and carried the title of Duke of Rong. In 618, while Emperor Yang of Sui was at Jiangdu with the Sui state engulfed in agrarian rebellions, the general Yuwen Huaji led a coup and overthrew Emperor Yang. Yuwen executed a large number of high level officials, and Lai Hu'er, along with most of his family, was killed. Only Lai Ji and his older brother Lai Heng escaped death. It was said that Lai Ji, because his family had suffered such disaster and he had himself escaped many dangers, was particularly studious. He was said to be a good writer and good at rhetoric and analyzing situations. He did well in imperial examinations and was able to become an imperial official.
During Emperor Taizong's reign
As of 643, during the reign of Tang Dynasty's second emperor Emperor Taizong, Lai Ji was serving as a low level official at the legislative bureau of government. That year, Emperor Taizong's son and crown princeLi Chengqian was discovered to have plotted to overthrow Emperor Taizong, and Emperor Taizong requested opinions from his officials as to what to do with Li Chengqian. No one dared to speak up, but Lai said, "The best possible outcome is that Your Imperial Majesty can remain a kind father and that the Crown Prince can live out his years." Emperor Taizong agreed, and he deposed Li Chengqian to commoner rank but spared Li Chengqian's life. In 644, after Emperor Taizong had created another son, Li Zhi, to be the new crown prince, he could not find an appropriate person to serve the role of brainstormer for Li Zhi, and so he commissioned Lai. Lai was also made a scholar at the imperial think tank, Chongxian Pavilion. He was soon made a mid-level official at the legislative bureau and commissioned to edit the Book of Jin—the official history of Jin Dynasty—with Linhu Defen.
During Emperor Gaozong's reign
In 649, Emperor Taizong died and was succeeded by Li Zhi. In 651, Lai Ji was made Zhongshu Shilang, the deputy head of the legislative bureau, and he became an official in charge of editing the imperial history. In 653, he was given the designation of Tong Zhongshu Menxia Sanpin, making him a chancellor de facto. In 654, he was further given the honorific title of Yinqing Guanglu Daifu and, for his contributions in editing the histories, created the Baron of Nanyang. In 655, he was made Zhongshu Ling, the head of the legislative bureau and a post considered one for a chancellor, as well as the acting minister of civil service. At that time, Emperor Gaozong, who greatly favored his concubineConsort Wu, was considering deposing his wife Empress Wang and replacing her with Consort Wu. He first considered creating Consort Wu the unprecedented title of Chenfei, but Lai and fellow chancellor Han Yuan opposed the move on the basis that the title was unprecedented, so Emperor Gaozong relented. However, in 655, he, over the explicit opposition of Lai, Han, and the highly regarded chancellor Chu Suiliang, as well as the implicit disapproval by his own powerful uncle Zhangsun Wuji, deposed Empress Wang and replaced her with Consort Wu. After Empress Wu's ascension, she submitted a petition ostensibly praising the faithfulness of Han and Lai in opposing the unprecedented Chenfei title, but showing instead that she remembered that they had offended her. In 656, after Empress Wu's son Li Hong was created crown prince, Lai was made a junior advisor to the young crown prince, and his title was upgraded to that of a marquess. In 657, however, with Empress Wu and her allies Xu Jingzong and Li Yifu beginning to carry out a series of reprisals against officials who had opposed Empress Wu's ascension, Xu and Li falsely accused Han and Lai of encouraging Chu to rebel. Emperor Gaozong demoted both Han and Lai to be prefects of distant prefectures—in Lai's case, the prefect of Tai Prefecture -- and ordered that they be permanently barred from returning to the capital Chang'an. However, he was able to escape further reprisals in 659, when by Empress Wu's instigations Zhangsun was forced to commit suicide and Empress Wang's uncle Liu Shi was executed. In 660, though, Lai's post was moved to the even more distant Ting Prefecture, on the borders with Western Tujue. In 661, Western Tujue forces attacked Ting Prefecture. Lai gathered his forces to resist, and he told his subordinates, "I should have been executed a long time ago, and it is fortunate that I was spared. This is the time that I should sacrifice my body for the empire." He therefore engaged Western Tujue forces without wearing armor, and he was killed in battle. He was posthumously honored, and his casket was returned to his home territory to be buried.
