paragraph_text: The Cultural Revolution, formally the Great Proletarian Cultural Revolution, was a sociopolitical movement in China from 1966 until 1976. Launched by Mao Zedong, then Chairman of the Communist Party of China, its stated goal was to preserve Chinese Communism by purging remnants of capitalist and traditional elements from Chinese society, and to re-impose Mao Zedong Thought (known outside China simply as Maoism) as the dominant ideology within the Party. The Revolution marked Mao's return to a position of power after the failures of his Great Leap Forward. The movement paralyzed China politically and negatively affected both the economy and society of the country to a significant degree. An estimated 500,000 to 2,000,000 people were killed.The movement was launched in May 1966, after Mao alleged that bourgeois elements had infiltrated the government and society at large, aiming to restore capitalism. To eliminate his rivals within the Communist Party of China (CPC), Mao insisted that revisionists be removed through violent class struggle. China's youth responded to Mao's appeal by forming Red Guard groups around the country. The movement spread into the military, urban workers, and the Communist Party leadership itself. It resulted in widespread armed clashes between conservative and radical factions in all walks of life, as a result of Mao's open call for "all-round civil war" against the conservatives in the communist party establishment. In the top leadership, it led to a mass purge of senior officials, most notably Liu Shaoqi and Deng Xiaoping. During the same period, Mao's personality cult grew to immense proportions.
