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 the country as a whole. 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.
