Chinese Communist Party

Explanation:

The Chinese Civil War was a conflict that was fought between the Communist Party of China, led by Mao Zedong, and the government of the Republic of China led by the Kuomintang. The war lasted intermittently between 1927 and 1949. The final phase of the war took place from 1945-1949, and is generally referred to as the Chinese Communist Revolution. At the end of the war, the Communists gained control of mainland China, while the Republic of China retreated to Taiwan. No official armistice or peace treaty was ever signed.
