Li Xi, chancellor of the Tang Dynasty

Li Xi or Li Qi, courtesy name Jingwang (景望), nicknamed Li Shulou (李書樓), was an official of the Chinese Tang dynasty, serving briefly as a chancellor during the reign of Emperor Zhaozong. With imperial power dwindling, Li Xi's fellow chancellor Cui Zhaowei, who associated with the warlords Li Maozhen, Wang Xingyu, and Han Jian, encouraged Li Maozhen, Wang, and Han to march on the capital Chang'an. Once the three warlords arrived in Chang'an, they put Li Xi and his fellow chancellor Wei Zhaodu to death.

The chancellor was a semi-formally designated office position for a number of high-level officials at one time during the Tang dynasty of China. This list also includes chancellors of the short-lived Wu Zhou dynasty, which is typically treated as an interregnum of the Tang dynasty by historians.

The Tang dynasty, or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty.
