Li Yichang

Li Yichang () (d. 909/910) was an ethnically-Dangxiang warlord of the Chinese Five Dynasties and Ten Kingdoms state Later Liang, ruling Dingnan Circuit (定難, headquartered in modern Yulin, Shaanxi) from 908 to his death in 909 or 910, as its military governor ("Jiedushi") in "de facto" independence.
Biography.
It is not known when Li Yichang was born. The traditional histories conflict on Li Yichang's relationship with his predecessor Li Sijian. The "History of the Five Dynasties", the "New History of the Five Dynasties", and the "Zizhi Tongjian" all indicated that he was Li Sijian's son. However, the "History of Song" indicated that he was the grandson of Li Sijian's predecessor and older brother Li Sigong.
In any case, when Li Sijian died in 908, Li Yichang claimed the title of acting military governor of Dingnan. Shortly after, Later Liang's emperor Zhu Quanzhong bestowed on him the title of full military governor.
Li Yichang's rule of Dingnan was short. In 909 or 910, his officer Gao Zongyi () mutinied and killed him. The officers and soldiers of Dingnan then killed Gao and supported Li Renfu—a relative of Li Yichang's, one generation higher—as the new ruler of Dingnan. Li Renfu was thereafter made the new military governor by Zhu Quanzhong. (Li Yichang's death year was given as 909 by the "History of the Five Dynasties" and the "New History of the Five Dynasties" and 910 by the "Zizhi Tongjian".)
