Mao Zedong, also called Mao Tse-tung, (December 26, 1893-October 27, 1962) was the Chairman of the Communist Party of China. Mao's communist party was at war with Chaing Kai-Shek's KMT during the Chinese Civil War in 1930s and the late 1940s. He briefly cooperated with the KMT against Japan during the Second Sino-Japanese War. The communists emerged victorious on the mainland, with Mao declaring the People's Republic of China on October 1, 1949.
During the Korean War, Mao ordered the intervention of People's Volunteer Army Units to fight against the US-led United Nations forces. It is notable that PVA's entry into the war caused the UN back into the 38th parallel, leading to a signing of an armistice in 1953. Mao would then initiate economic and social reform in 1958 known as the Great Leap Forward. Its aim was to rapidly transform the country from an agrarian economy into a socialist society through rapid industrialization and collectivization. However, it is widely considered to have caused the Great Chinese Famine.
After Stalin's death, Mao had shaky relations with China's northern communist neighbor, the Soviet Union. While still allies by 1962, both the USSR and the PRC struggled for the leadership of communism worldwide. It would appear by the future that the Soviet Union and China would finally break away their alliance.
Mao was killed in Beijing on October 27, 1962 when the United States launched several nuclear missiles towards countless Chinese and Soviet cities. His death caused the collapse of China in to different states. However, in 1987, the People's Republic of China, a Soviet satellite state, was re-established in Manchuria on the "invitation" of exiled Chinese government officials.
