History of the Republic of China
On the other hand, since the failure of the Second Revolution, Sun Yat-sen and his allies were trying to rebuild the revolutionary movement. In July 1914 Sun established the Chinese Revolutionary Party (). He felt that his failures at building a consistent revolutionary movement stemmed from the lack of cohesiveness among its members. To that end, Sun required that party members to be totally loyal to Sun and follow a series of rather harsh rules. Some of his earlier associates, including Huang Xing, balked at the idea of such authoritarian organization and refused to join Sun. However, they agreed that the republic must not revert to imperial rule.
Chinese Civil War
The Chinese Civil War was a war fought between the Kuomintang (KMT)-led government of the Republic of China and the Communist Party of China (CPC). Although particular attention is paid to the four years of Chinese Communist Revolution from 1945 to 1949, the war actually started in August 1927, with the White Terror at the end of Generalissimo Chiang Kai-shek's Northern Expedition, and essentially ended when major hostilities between the two sides ceased in 1950. The conflict took place in two stages: the first between 1927 and 1937, and the second from 1946 to 1950, with the Second Sino-Japanese War in 1937–1945 separating them. The war marked a major turning point in modern Chinese history, with the Communists gaining control of mainland China and establishing the People's Republic of China (PRC) in 1949, forcing the Republic of China (ROC) to retreat to Taiwan. It resulted in a lasting political and military standoff between the two sides of the Taiwan Strait, with the ROC in Taiwan and the PRC in mainland China both officially claiming to be the legitimate government of all China.
