Mao Zedong was a Chinese politician, revolutionary, and political theorist who founded the People's Republic of China in 1949 and led the country from its establishment until his death in 1976. Mao served as Chairman of the Chinese Communist Party from 1943 until his death, and as the party's de facto leader from 1935. His theories, which he advocated as a Chinese adaptation of Marxism–Leninism, are known as Maoism.
Born to a peasant family in Shaoshan, Hunan, Mao studied in Changsha and was influenced by the 1911 Revolution and ideas of Chinese nationalism and anti-imperialism. He was introduced to Marxism while working as a librarian at Peking University, and later participated in the May Fourth Movement of 1919. In 1921, Mao became a founding member of the CCP. After the start of the Chinese Civil War between the Kuomintang and CCP, Mao led the failed Autumn Harvest Uprising in Hunan in 1927, and in 1931 founded the Jiangxi Soviet. He helped build the Chinese Red Army, and developed a strategy of guerilla warfare. In 1935, Mao became leader of the CCP during the Long March, a military retreat to the Yan'an Soviet in Shaanxi, where the party began rebuilding its forces.
