Chiang Kai-shek was a Chinese politician, revolutionary, and military leader. He was the head of the Nationalist Kuomintang (KMT) party, General of the National Revolutionary Army, known as Generalissimo, and the leader of the Republic of China (ROC) in mainland China from 1928 until 1949. After being defeated in the Chinese Civil War by the Chinese Communist Party (CCP) in 1949, he led the ROC on the island of Taiwan until his death in 1975.

The Chinese Civil War was fought between the Kuomintang-led government of the Republic of China and the forces of the Chinese Communist Party (CCP), with armed conflict continuing intermittently from 1 August 1927 until 7 December 1949, resulting in a CCP victory and control of mainland China in the Chinese Communist Revolution.
