오초칠국의 난
In 179 BC, Zhao was granted to Liu Sui, son of Liu You. A year later, Hejian was created as a separate kingdom. Sui rebelled during the Rebellion of the Seven States and was defeated. Liu Pengzu (劉彭祖), a son of Emperor Jing was named the new Prince of Zhao. Thereafter, Zhao was reduced to a fraction of its former size, and only covered Handan Commandery.
