Emperor An
Liu Yi was the son of Liu Kai (), the Prince of Hejian (and therefore a grandson of Emperor Zhang), and he had initially been made the Prince of Pingyuan as the heir of his cousin Liu Sheng () by Empress Dowager Deng Sui, the regent for Emperor An, who was impressed with his abilities. That led to rumors that Empress Deng was looking to replace Emperor An, Prince Yi's cousin, with Prince Yi. After Empress Dowager Deng died in 121, Emperor An, bearing a grudge against Prince Yi, demoted him to the rank of Marquess of Duxiang and exiled him to his father's principality. During the reign of Emperor Shun, Prince Kai requested that he be allowed to give Liwu County, part of his principality, to his son, and Emperor Shun permitted it. Marquess Yi thus became the Marquess of Liwu.
