The Rebellion of the Seven States or Revolt of the Seven Kingdoms (simplified Chinese: 七国之乱; traditional Chinese: 七國之亂; pinyin: Qī Guó zhī Luàn) took place in 154 BC against the rule of Emperor Jing of the Western Han dynasty by its regional semi-autonomous kings, to resist the emperor's attempt to centralize the government further. The rebellion was crushed by the Western Han imperial forces within three months, and the powers of the imperial court grew exponentially afterward.
