冉闵
After Liu Cong's death, the kingdom was split between Liu Yao and General Shi Le. Shi Le was an ethnic Jie who had worked as an indentured farm laborer before joining Liu Yuan's rebellion and becoming a powerful general in Hebei. In 319, he founded a rival Zhao Kingdom, known as the Later Zhao and in 328 conquered Liu Yao's Former Zhao. Shi Le instituted a dual-system of government that imposed separate rules for Chinese and non-Chinese, and managed to control much of northern China. After his death, his sons were locked in a fratricidal succession struggle and the kingdom was ended in 350 by General Ran Min, an ethnic Chinese who seized the throne and founded the Ran Wei. Ran Min favored Han Chinese and massacred thousands of Jie. He was defeated and killed in 352 by the Murong Xianbei from Liaodong.
