After the death of Sun Yat-sen, Chiang Kai-shek led the National Revolutionary Army founded by him to carry out the Northern Expedition, thus completing the reunification of China in name. Because the main leaders who participated in the revolution at that time, especially He (Wang Jingwei), were all leaders trained by Sun, the national government at that time should regard Sun as the highest spiritual leader and recommend the Three People's Principles as the highest guidance for governing the country. 1937 after the outbreak of War of Resistance against Japanese Aggression, Sun became one of the symbols of national centripetal force. The national government and its generals often call for "safeguarding the revolutionary achievements of Premier Sun" to encourage people to build and fight against soldiers. Therefore, in the middle and late period of the Anti-Japanese War, Sun Yat-sen was naturally elected as the founding father of the Republic of China.
For the analysis of Sun Yat-sen's historical contribution, it is mainly believed that Sun Yat-sen was indeed a leader who advocated * * * and revolution in modern times, successfully organized various anti-Qing forces with complex components, and injected modern western political theory and constitutional thought. Although Sun Yat-sen also attached importance to mastering the power of leaders, he was more idealistic and could give up political resources for the needs of system construction. Although Sun Yat-sen advocated overthrowing the autocratic monarchy by force and pacifying the warlord regime by force, his method was moderate, and the measures of rehabilitation were tolerant, and he did not take the practice of thorough eradication, which was different from that of Chiang Kai-shek or Mao Zedong who emphasized organizational discipline and severely punished opponents.
Sun Yat-sen is also an important stage figure in China's political and economic modernization. Sun Yat-sen comprehensively integrated the important elements of modern western bourgeois democratic thought, including constitutional democracy, people's sovereignty (election, recall, creation, referendum), separation of powers, socialism and so on. In addition, China's traditional institutional institutions-supervision power and review power, which he personally considered necessary, formed the five-power constitutional theory. The popularization of important western ideas in China has the role of a promoter, which has promoted the westernized democrats and * * * producers to explore the future construction of China. Sun Yat-sen, on the other hand, took a compromise position, but it still has its value to adhere to the democratic constitutional system.
