Trotskyism arose as a possible alternative to the NEP. He personified the mass protest of the industrial proletariat of our country against the huckstering and thieving Soviet capitalism. But very quickly and imperceptibly, he lost all his ideological positions, turning into a club of unprincipled political adventurers, ready to destroy the USSR and all its achievements for the sake of power. This metamorphosis is what this book is dedicated to. The book is dedicated to the political struggle in the CPSU (b) and the internal politics of the USSR in the period after the end of the civil war (1922) and until the final victory of Stalin (1934). The appendix contains brief biographies of oppositionists and participants in the defeat of the opposition. For students of the history of the USSR, political history, political science.
