Peng Yue
In 205 BC, Peng Yue allied with Liu Bang, the King of Han, and became one of Liu's generals after Liu promised to grant him land and the title of a vassal king. Earlier on, Peng Yue had refused to send his troops to help Liu Bang, that resulted in the latter's defeat by Xiang Yu at the Battle of Guling. Three years later, Peng Yue conquered more than 20 cities around Changyi and acquired a large amount of supplies. He then led his troops southwards and joined the armies of Han Xin and Liu Bang at the Battle of Gaixia against Xiang Yu. Peng Yue's contributed greatly to the eventual Han victory over Xiang Yu. After Liu Bang founded the Han dynasty, Peng Yue was conferred the title of "King of Liang" () and granted the lands of former Wei state as his kingdom.
