Kuomintang [SEP] Introduction
The KMT was founded by Song Jiaoren and Sun Yat-sen shortly after the Xinhai Revolution of 1911. Sun was the provisional President, but he ceded the presidency to Yuan Shikai. Yuan's death in 1916 led to the nation's disintegration in the Warlord Era. Sun deputed Chiang Kai-shek to form the National Revolutionary Army and launch the Northern Expedition that unified much of mainland China and established the capital at Nanjing. During the following Nanjing decade China achieved substantial economic growth and social progress, but the Second Sino-Japanese War (1937–1945) was disastrous. After the loss of the Chinese Civil War (1945–1949) to the Communist Party of China the KMT retreated to Taiwan where it continued to govern as an authoritarian one-party state.
