In 1927, civil war erupted in China, between the Chinese Nationalist Party and the Communist Party of China. Externally, the Nationalists were supported by the West and the Communists by the Soviets. In China today, the conflict is referred to as the "War of Liberation".
The war was interrupted in 1937 when the two sides united against the Japanese invasion. After World War II, the civil war resumed, only ending when the Nationalist leadership of Chiang Kai-shek fled to Taiwan in 1949.
