Dang Guo (Chinese: 黨國; pinyin: Dǎngguó; lit. 'party-state') was the one-party system adopted by the Republic of China under the Kuomintang. It was from 1924 onwards, after Sun Yat-sen acknowledged the efficacy of the nascent Soviet Union's political system (notably governance under a dictatorship). Chiang Kai-shek later used the Kuomintang to control and operate the National Government of the Republic of China (ROC) and the National Revolutionary Army. All of the major national policies of the government bureaucracy were formulated by the Kuomintang, resulting in the party holding the supreme power of the whole nation. In Sun Yat-sen's belief, rule over the state should have been returned to the people after the National Revolutionary Army militarily ended the Warlord Era.
