After the end of World War II, the Chinese Civil War resumed between the Chinese Nationalists (Kuomintang), led by Generalissimo Chiang Kai-shek, and the Chinese Communist Party (CCP), led by CCP Chairman Mao Zedong. Throughout the months of 1949, a series of Chinese Communist offensives led to the capture of its capital Nanjing on 23 April and the subsequent defeat of the Nationalist army on the mainland, and the Communists founded the People's Republic of China on 1 October.
