Li Renfu (李仁福) (died March 10, 933[1][2]), possibly né Tuoba Renfu (拓拔仁福), formally the Prince of Guo (虢王), was an ethnic Dangxiang (Tangut) warlord during the Five Dynasties and Ten Kingdoms period, ruling Dingnan Circuit (定難, headquartered in modern Yulin, Shaanxi) from 909 or 910 to his death in 933, as its military governor (jiedushi) in de facto independence.
[6] Later in 910, Li Maozhen the Prince of Qi—one of the rival states to Later Liang—as well as two military governors under him, Li Jihui the military governor of Jingnan Circuit (靜難, headquartered in modern Xianyang, Shaanxi) and Liu Zhijun the military governor of Zhangyi Circuit (彰義, headquartered in modern Pingliang, Gansu)—sent emissaries to Li Cunxu, the Prince of Jin (another rival state to Later Liang), suggesting that they attack Dingnan together.
The two armies put Dingnan's capital Xia Prefecture (夏州, in modern Yulin, Shaanxi) under siege.
[6] For his holding out against Qi and Jin, Zhu bestowed on Li Renfu the titles of acting Taibao (太保) and honorary chancellor (同中書門下平章事, Tong Zhongshu Menxia Pingzhangshi).
The attempt failed, and Li Renfu's family would become entrenched at Dingnan for the rest of the Five Dynasties and Ten Kingdoms period.
