Overview
Li Keyong (October 24, 856 – February 24, 908) was a Chinese military general and politician of Shatuo ethnicity, and from January 896 the Prince of Jin, which would become an independent state after the fall of the Tang dynasty in 907. Li served as a Jiedushi provincial military governor during the late Tang period and was an instrumental figure in the development of a Shatuo base of power in what is today's Shanxi Province of China. His son Li Cunxu (Emperor Zhuangzong), a child of his concubine Lady Cao, would succeed him as Prince of Jin and eventually become the founding emperor of the Later Tang dynasty in 923.
Background
Li Keyong—although he would have initially carried the surname of Zhuye—was born in 856, during the reign of Emperor Xuānzong. His father was the Shatuo chieftain Zhuye Chixin, whose people were then living in the Shenwu River (神武川, flowing through modern Shuozhou, Shanxi) region. His mother was Lady Qin, and it is not clear whether she was Zhuye Chixin's wife or concubine. He was Zhuye Chixin's third son.
In 869, during the reign of Emperor Xuānzong's son Emperor Yizong, as the Tang imperial general Kang Chengxun was commissioned to suppress the rebellion of Pang Xun at Xu Prefecture (徐州, in modern Xuzhou, Jiangsu), he invited Zhuye to bring his Shatuo soldiers and serve under him. Zhuye agreed, and then-14-year-old Li Keyong fought in the campaign so fiercely that he became known as the "Son of the Flying Tiger" (飛虎子). After the campaign, to recognize Zhuye Chixin's contributions during the campaign, Emperor Yizong bestowed on him the imperial surname of Li, and gave him a new name of Guochang. Li Keyong presumably took the imperial surname of Li at that time as well. Li Guochang was subsequently made the military governor (Jiedushi) of Zhenwu Circuit (振武, headquartered in modern Hohhot, Inner Mongolia). Li Keyong went to Zhenwu as well to serve under his father.
