The Chinese Communist Revolution was a social and political revolution in mainland China that began in 1927 and culminated with the proclamation of the People's Republic of China (PRC) in 1949. The revolution was led by the Chinese Communist Party (CCP), which afterwards became the ruling party of China. The political revolution resulted in major social changes within China and has been looked at as a model by revolutionary communist movements in other countries.
During the preceding century, termed the century of humiliation, the decline of the Qing dynasty and the rise of foreign imperialism caused escalating social, economic, and political problems in China. The Qing collapsed in 1912 and were replaced with the Republic of China, which had itself fallen into warring factions by 1917. A small group of urban intellectuals, inspired by the October Revolution and European socialist ideas, founded the CCP in 1921. They created an alliance known as the First United Front with the much larger Kuomintang (KMT), having the shared goal of overthrowing the warlords governing China. During this period the CCP rapidly expanded its membership, organized a militant labor movement in several of China's major cities, and established rudimentary peasant associations in rural areas. Nonetheless, and despite the First United Front's military successes, KMT leader Chiang Kai-shek ended the alliance in 1927 by initiating the Shanghai massacre.
