The Chinese Civil War, 1945-1950, fought between the Chinese Communist Party (CCP) and the Nationalist Party (GMD), was a defining conflict for China, East Asia, and the world. The Civil War was marked by a number of large battles and campaigns and the involvement of both the United States and the Soviet Union. The victory of the CCP and the founding of the People's Republic of China in October 1949 shifted the balance of power in the emerging Cold War.
