Peng Zhen was a leading member of the Chinese Communist Party. He led the party organization in Beijing following the victory of the Communists in the Chinese Civil War in 1949, but was purged during the Cultural Revolution for opposing Mao's views on the role of literature in relation to the state. He was rehabilitated under Deng Xiaoping in 1982 along with other 'wrongly accused' officials, and became the inaugural head of the Central Political and Legal Affairs Commission.

The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC). It was launched by Mao Zedong in 1966 and lasted until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. Though it failed to achieve its main objectives, the Cultural Revolution marked the effective return of Mao to the center of power in China after his political sidelining, in the aftermath of the Great Leap Forward and the Great Chinese Famine.
