Throughout the Soviet history millions of people became victims of Soviet political repression, which was an instrument of the internal politics of the Soviet Russia and Soviet Union since the first days after the October Revolution. Culminating during the Stalin era, it still existed during the "Khrushchev Thaw," followed by increased persecution of Soviet dissidents during Brezhnev stagnation, and didn''t cease to exist during Gorbachev''s perestroika. Its heritage still influences the life of the modern Russia. Early on the theoretical basis of the repressions was the Marxist view at the class struggle and the resulting notion of the dictatorship of the proletariat. Its legal basis was formalized into the Article 58 in the code of RSFSR and similar articles for other Soviet republics.
