Mao Zedong
(born Dec. 26, 1893, Shaoshan, Hunan province, China — died Sept. 9, 1976, Beijing) Chinese Marxist theorist, soldier, and statesman who led China's communist revolution and served as chairman of the People's Republic of China (1949 – 59) and chairman of the Chinese Communist Party (CCP; 1931 – 76). The son of a peasant, Mao joined the revolutionary army that overthrew the Qing dynasty but, after six months as a soldier, left to acquire more education. At Beijing University he met Li Dazhao and Chen Duxiu, founders of the CCP, and in 1921 he committed himself to Marxism. At that time, Marxist thought held that revolution lay in the hands of urban workers, but in 1925 Mao concluded that in China it was the peasantry, not the urban proletariat, that had to be mobilized. He became chairman of a Chinese Soviet Republic formed in rural Jiangxi province; its Red Army withstood repeated attacks from Chiang Kai-shek'（蒋介石）s Nationalist army but at last undertook the Long March to a more secure position in northwestern China. There Mao became the undisputed head of the CCP. Guerrilla warfare tactics, appeals to the local population's nationalist sentiments, and Mao's agrarian policies gained the party military advantages against their Nationalist and Japanese enemies and broad support among the peasantry. Mao's agrarian Marxism differed from the Soviet model, but, when the communists succeeded in taking power in China in 1949, the Soviet Union agreed to provide the new state with technical assistance. However, Mao's Great Leap Forward and his criticism of "new bourgeois elements" in the Soviet Union and China alienated the Soviet Union irrevocably; Soviet aid was withdrawn in 1960. Mao followed the failed Great Leap Forward with the Cultural Revolution, also considered to have been a disastrous mistake. After Mao's death, Deng Xiaoping began introducing social and economic reforms.

Mao Zedong
A Chinese revolutionary leader of the twentieth century. He led an army of workers and peasants on the Long March in the 1920s and used guerrilla warfare techniques successfully on both the Japanese invaders and the forces of the Chinese government under Chiang Kai-shek. In 1949, his armies took over the country and established the People's Republic of China. Mao continued as chairman of China's Communist party and as premier. His “Little Red Book,” Quotations from Chairman Mao, was standard reading for schoolchildren of the country. Toward the end of his life, he brought about the Great Proletarian Cultural Revolution, in which all capitalist or elitist culture was to be purged. Mao died in 1976.
