Founding of the Later Jin
The first sinicized Shatuo ethnicity state, Later Tang, was founded in 923 by Li Cunxu, son of the great Shatuo chieftain Li Keyong. It extended Shatuo domains from their base in Shanxi to most of North China, and into Sichuan.
After Li Cunxu’s death, his adopted son, Li Siyuan became emperor. However, the Shatuo relationship with the Khitans, which was vital to their rise to power, had soured. Shi Jingtang, the son-in-law of Li Cunxu, rebelled against him, and with the help of the Khitan, declared himself emperor of the Later Jin in 936.
The Later Jin founder Shi Jingtang claimed patrilineal Han Chinese ancestry.
There were Dukedoms for the offspring of the royal families of the Zhou dynasty, Sui dynasty, and Tang dynasty in the Later Jin. This practice was referred to as 二王三恪.
The Tang Imperial Longxi Li lineage 隴西李氏 also included sub lineages like the Guzang Li 姑臧李, from which Li Zhuanmei 李專美 came from, who served the Later Jin.
