Rebellion of the Seven States
After Crown Prince Qi ascended to the throne and became Emperor Jing of Han, based on the advice from Chao Cuo, Emperor Jing began to centralize power in an attempt to reduce the strength of the regional princes. In 154 BC, Liu Pi convinced six other princes to rebel against the emperor, thereby starting the Rebellion of the Seven States. The emperor appointed Zhou Yafu as commander and he defeated Liu Pi's army. Liu Pi was killed during the battle and his title was abolished.
