The Great Russian chauvinism is part of more common Great-Power chauvinism or chauvinism in general. According to the Great Soviet Encyclopedia (GSE), Great-Power chauvinism is an ideology of the "dominant exploiting classes of the nation, holding a dominant (sovereign) position in the state, declaring their nation as the "superior" nation". The GSE defines chauvinism as an extreme form of nationalism and acknowledges the existence of great-national chauvinism in the Russian Empire as well as other countries across the globe.
Following the October Revolution, in September of 1922 Lenin wrote to a letter to Politburo stating, "we consider ourselves, the Ukrainian SSR, and others equal and enter with them on an equal basis into a new union, a new federation, the Union of the Soviet Republics of Europe and Asia". Lenin also promoted an idea for the Bolshevik party to defend the right of oppressed nations within the former Russian Empire to self-determination and equality as well as the language-rights movement of the newly-formed republics.
Moreover, in December of 1922 Lenin in his letter "What practical measures must be taken in the present situation?" wrote, "...Thirdly, exemplary punishment must be inflicted on Comrade Ordzhonikidze (I say this all the more regretfully as I am one of his personal friends and have worked with him abroad) and the investigation of all the material which Dzerzhinsky's commission has collected must be completed or started over again to correct the enormous mass of wrongs and biased judgments which it doubtlessly contains. The political responsibility for all this truly Great-Russian nationalist campaign must, of course, be laid on Stalin and Dzerzhinsky."
