Peng Zhen
The Anti-Rightist Campaign () in the People's Republic of China, which lasted from 1957 to roughly 1959, was a political campaign to purge alleged "Rightists" within the Chinese Communist Party (CCP) and abroad. The campaign was launched by Chairman Mao Zedong, but Deng Xiaoping and Peng Zhen also played an important role. The Anti-Rightist Campaign significantly damaged democracy in China and turned the country into a "de facto" one-party state.
