Liu Pengli (Chinese: 劉彭離) of China, third child of Prince Xiao of Liang or King of Liang (梁孝王), grandson of Emperor Wen of Han (漢文帝) and cousin of Emperor Jing of Han (漢景帝). His four brothers are, in a descending order of age, Liu Mai (劉買), Liu Ming (劉明), Liu Ding (劉定)and Liu Bushi (劉不識).
Liu was made Prince of Jidong (濟東王) in the sixth year of the middle reign of Emperor Jing (144 BC), when Empress Dou (竇皇后) mourned over Prince Xiao of Liang's death. His brothers took one the other four parts of Liang. According to the Chinese historian Sima Qian (司馬遷), "twenty-nine years later, he was arrogant and cruel, and would go out on marauding expeditions with tens of slaves or young men who were in hiding from the law, murdering people and seizing their belongings for sheer sport. Confirmed victims exceeded 100, and these murders were known across the kingdom, so people were afraid of going out of their houses at night. Eventually the son of one of his victims accused him to the Emperor, and the officials of the court requested that Liu Pengli be executed; however, the emperor could not bear to have his own cousin killed, and Liu Pengli was made a commoner and banished to the county of Shangyong (上庸縣), now Zhushan County (竹山縣), in Hubei Province (湖北省) of China. His sovereignty was abolished, and his land was reclaimed by Emperor Jing."
