Emperor Wen's Strategic Ministerial Control Secures Dynasty's Prosperity, Avoids Downfall.
During the Han Dynasty, Emperor Wen and the Princes of Dai and Changyi relied on their ministers to maintain power. Emperor Wen successfully consolidated his rule by putting the imperial guards under a minister of Dai, leading to prosperity. In contrast, Prince Changyi failed to follow Emperor Wen's example, leading to his dethronement by the powerful court minister Huo Guang.
