The concept and thought of "internationalism" was first put forward by Marx and Engels, the founders of scientific materialism. "Workers have no motherland", "Proletarians all over the world unite!" These two famous theories embody the thought of internationalism. The international proletariat unites against international capitalism, establishes proletarian dictatorship and realizes * * * productism, which is the core content of internationalism. When talking about the relationship between internationalism and national interests, classic writers pointed out that "the international movement of the proletariat is only possible within the scope of independent nationalities", "national independence is the basis of all international cooperation" and "if the proletariat allows its own nationality to take a little violence against other nationalities, it is not a socialist proletariat".

Lenin proposed and used the concept of "proletarian internationalism" earlier. At the beginning of the victory of the October Revolution, Soviet Russia was engaged in a desperate struggle with enemies at home and abroad, eager for the support and assistance of the international proletariat, and the rapidly rising European revolutionary situation at that time provided great practical possibilities for this. Therefore, the category of internationalism mentioned by Lenin in this period mainly refers to the relationship between nation-states (such as Soviet Russia and Germany, Poland, Hungary, etc. ), and the core content of internationalism refers to the world revolution, especially the European revolution. Lenin advocated that "the proletarians and oppressed nations of the world unite!" Famous slogan. Defending the newborn Soviet Russia is regarded as the direct goal of internationalism. With the end of the war and the shift of the focus of Soviet Russia's work, with the world revolution, especially the European revolution, moving from high tide to low tide, with the establishment of a unified Soviet state and the rise of great Russian within the party, Lenin's internationalism has changed, its scope has expanded from a nation-state to a socialist country, and the equality and unity of all ethnic groups within the Soviet Union (such as the relationship between Russia and Ukraine and Georgia) has risen to the height of internationalism, and it has been classified into the category of internationalism, repeatedly stressing the need to oppose great Russian. But Lenin did not give up the idea of world revolution, but waited for new opportunities and tried to influence and promote the world revolution through the practical example of Soviet socialism.

Stalin failed to develop and perfect internationalism in theory and practice with the development of the times: his insistence on internationalism was insufficient, while pragmatism was considered too much. Based on the theory that the Soviet Union built socialism in one country, Stalin very pragmatically equated the interests of the Soviet Union with internationalism and regarded * * * production as a tool to serve the national interests of the Soviet Union. On the issue of ethnic relations within the Soviet Union, Stalin equated opposing Russian chauvinism with opposing local nationalism, but actually emphasized opposing local nationalism. Especially during the Second World War, Stalin put away the banner of internationalism and mobilized the whole people to resist German defenders under the banner of Russian nationalism. In Stalin's view, since internationalism is not conducive to defending the Soviet Union, it should be abandoned, and the banner of nationalism is conducive to defending the Soviet Union and should be held high.

After the war, the cold war pattern between the United States and the Soviet Union gradually took shape, and the socialist system appeared in Eastern Europe. In this case, Stalin began to talk about proletarian internationalism again. 1948, the Intelligence Bureau of the * * * Production Party expelled Yugoslavia on the grounds of "nationalism" and "violation of the principle of proletarian internationalism", and launched a campaign to eliminate "Titonists" and oppose "right-wing nationalism" in Eastern European countries. Stalin regarded whether to implement the Soviet model and respect Soviet leadership as the touchstone to test true and false internationalism.

Khrushchev and Brezhnev inherited Stalin's view of internationalism. The term "big socialist family" originated in Khrushchev's period. The terms "Oriental Group", "proletarian internationalism" and "socialist internationalism" have almost become a mantra. Khrushchev said that "all socialist countries, like soldiers in line, should be equal to their leaders". The famous "Brezhnevism" theory embodies Brezhnev's understanding and practice of internationalism. Its main contents are: the "international dictatorship theory" of the proletariat; Soviet Union's "Great Power Responsibility Theory"; "Limited sovereignty theory" of other socialist countries. Internationalism has been seriously deformed and has become the theory of Soviet intervention and control of other socialist countries.

The spirit of internationalism is a spirit of peace, relevance and rationality. It can make people know right from wrong, and let people know how to tolerate others and who to tolerate.
