The KMT and CCP initially cooperated in the First United Front during the Northern Expedition against warlords in 1926–1927. When that alliance collapsed, armed conflict erupted on 1 August 1927. A brief interlude occurred during 1937–1945 when both sides formed the Second United Front to resist the Japanese invasion, though armed clashes between them remained frequent.
The civil war, fought in two main phases from 1927 to 1949, saw the Chinese Communist Party progressively gain military and political strength. After Japan's defeat in 1945, full-scale fighting resumed. The CCP gained the upper hand in the final phase (1945–1949), known as the Chinese Communist Revolution, driving KMT forces across much of mainland China.
The CCP established the People's Republic of China on the mainland in 1949, while the ROC leadership retreated to Taiwan. A prolonged political and military standoff across the Taiwan Strait followed, with both governments claiming legitimacy over all of China. Open conflict effectively ceased in 1979, but no formal peace treaty has ever been concluded.
