Early period: nationalism (expelling Tatars and restoring China), civil rights (establishing the Republic of China), and people's livelihood (equal land rights).
Later period: On this basis, unite with Russia and help the peasants and workers.
The following is a more detailed process of ideological transformation.
The first stage:1June, 894, Sun Yat-sen tasted the book "Li Shang Fu Xiang Shu" and put forward many reform suggestions, but Li Hongzhang refused. Disappointed, he went to Maui, Honolulu on June 24th, 165438, intending to raise funds to create the first revolutionary organization in his life-Xingzhonghui, and put forward the slogan of "expelling the Tatars, restoring China and establishing a coalition government", aiming at "rejuvenating China" and paving the way for his revolutionary cause by exhausting Manchu thoughts.
The second stage:1In August, 905, Japanese Uchida Ryohei joined Sun Yat-sen's "Zhong Xing Club", Huang Xing's "Hua Xing Club", Cai Yuanpei's "Patriotic Club" and Zhang Ji's "Youth Club" to establish the "China League" in Tokyo, Japan. Sun Yat-sen was promoted to the position of Prime Minister of the League, and once again defined "expelling the Tatars, restoring China, establishing the Republic of China and sharing land rights" as the revolutionary program, and reorganized the organ newspaper of the Huaxing Association, Twentieth Century Ji Zhina, into People's Daily. He first put forward the theory of "Three People's Principles" in Preface, that is, "national character, civil rights character and people's livelihood character", and had a fierce debate with reformists such as Liang Qichao and Kang Youwei. Then, the General Program of the League Revolution was compiled, and the national revolution was officially declared. Citing four vows, the Republic of China was established, and three procedures were set up: military law rule, contract law rule and constitutional rule.
The third stage: 1924 1, the first national congress of the Chinese Kuomintang was held in Guangzhou, and the declaration of reorganizing the Kuomintang was issued; Determine the three major policies of "alliance with Russia, alliance with * * *, and assistance to farmers and workers"; Re-interpret the old Three People's Principles as the new Three People's Principles through the new party program and the new party constitution; China Kuomintang was reorganized into a revolutionary alliance including workers, peasants, petty bourgeoisie and national bourgeoisie, thus realizing the first cooperation between the two countries. In October 165438+, Feng Yuxiang invited him to go north to "discuss the country". On his way to the north, he reiterated his opposition to imperialism and feudal warlords and put forward the slogan of convening a "national convention" and abolishing unequal treaties. 1March, 925 12, died in Beijing at the age of 59. On his deathbed, he pointed out in his will that "the revolution has not yet succeeded" and "the people must be aroused, and the nations that treat me equally in the world must be United to fight together".
Generally speaking, Sun Yat-sen's thoughts are embodied in the following aspects: 1, and the concept of "Three People's Principles" with "national character", "civil rights" and "people's livelihood" as the core. 2. advocate "separation of powers"-"people have rights and the government has the ability"; Carry out "universal government"-"promoting welfare and making great achievements" 3. Pay attention to "people's rights"-political power should have four items: "election, recall, initiative and referendum". 4. Pay attention to the "power of the government"-the separation of the five powers of "ruling, legislation, administration, justice, examination and supervision" is a "five-power constitution". 5. Explain the basic training and conditions for people to exercise political power: preliminary civil rights, that is, procedural rules. 6. Put forward the "equal rights system" between the central and local governments and "local autonomy" with the county as the unit. 7. In terms of economic thought, it advocates the theory of social mutual assistance: "The principle of human evolution is different from that of species evolution, and species take competition as the principle and human beings take mutual assistance as the principle." 8. In the aspect of political modernization, he advocated the three stages of gradualism, namely, military administration, political training and constitutionalism, and said: "During the military and political period, priority was given to eliminating warlords and bandits, and military control was implemented. During the political training, priority should be given to infrastructure construction and preliminary training of civil rights, and one party should be in power. The conditions for constitutional government are that more than half of the counties and cities in China have the conditions to recall local leaders by election and citizens have the conditions to initiate a referendum. Then they elected the National Assembly to formulate a constitution, return government to the people, and implement a modern political system of multi-party competition. " 9. Promoting regional cooperation and political structure based on kingship: Greater Asianism and industrial plans open to international investment.
