Chinese Civil War (1927 - 1950)

The Chinese Civil War was a civil war in China fought between forces loyal to the government of the Republic of China led by the Kuomintang (KMT) and forces of the Communist Party of China (CPC). The war began in April 1927, amidst the Northern Expedition, and essentially ended when major active battles ceased in 1950. The conflict eventually resulted in two de facto states, the Republic of China (ROC) in Taiwan and the People's Republic of China (PRC) in mainland China, both claiming to be the legitimate government of China.

Background
The Qing Dynasty, the last of the ruling Chinese dynasties, collapsed in 1911. China was left under the control of several major and lesser warlords in the Warlord era. To defeat these warlords, who had seized control of much of Northern China, the anti-monarchist and national unificationist Kuomintang party and its leader Sun Yat-sen, sought the help of foreign powers.
Sun Yat-sen's efforts to obtain aid from the Western democracies were ignored, however, and in 1921 he turned to the Soviet Union. For political expediency, the Soviet leadership initiated a dual policy of support for both Sun and the newly established Communist Party of China, which would eventually found the People's Republic of China. Thus the struggle for power in China began between the KMT and the CPC.
In 1923, a joint statement by Sun and Soviet representative Adolph Joffe in Shanghai pledged Soviet assistance for China's unification. The Sun-Joffe Manifesto was a declaration for cooperation among the Comintern, KMT and the Communist Party of China.

The CPC joined the KMT to form the First United Front.
