The Great Proletarian Cultural Revolution (shortened as the Cultural Revolution or GPCR) were a series of policies enacted by the Communist Party of China in order to eliminate bourgeois influence in China. This lasted from May 1966 until Mao's death.
The Cultural Revolution remains controversial amongst Marxist-Leninists due to nature it took place, as Anti-revisionist Marxists (specifically Maoists) support it, meanwhile those who support China in its modern form criticise the Cultural Revolution.
