Book excerpt: This volume examines the bloodiest period of the Stalinist repression of political opposition in the Soviet Union, debunking the myth that the Great Purges were merely the product of Stalin's paranoia and had no overriding political logic. Through a meticulous examination of original sources, including archival documents only made available for research in the 1990s, Professor Vadim Rogovin argues that the ferocity of the mass repression was directly proportional to the intensity of resistance to Stalin within the Communist Party of the Soviet Union (CPSU), particularly the opposition inspired by and associated with the exiled Bolshevik leader Leon Trotsky. Far from Trotsky being a politically isolated figure, as both Stalinist and anti-communist historians have claimed, there was substantial sympathy for his criticism of the Stalin regime in the ranks and even in the leadership of the CPSU, and support for his demands for inner-party democracy, greater social equality and an international orientation to the Bolshevik goal of world revolution. It was this political fact, as Rogovin demonstrates, that accounts for the purge reaching so deeply into the party apparatus, the military, the Komsomol youth movement, and the broader layers of the population. Rogovin bases his analysis on scrupulous research, quoting from newly translated or unpublished documents, including memoirs, meeting minutes, newspaper articles and trial transcripts. He documents the reaction of different social layers to the purges, including workers, peasants, non-party intellectuals and the CPSU rank-and-file. This book includes rarely published photographs of the prison camps, documenting the lives of those labeled by Stalin;enemies of the people. Chronologically, this volume takes up where its predecessor, 1937: Stalin's Year of Terror , left off, with the June 1937 plenum of the Central Committee that followed the purging of the Soviet military command and the execution of Marshal Tukhachevsky and other leading generals. It analyzes such critical events as the Bukharin-Rykov trial, last of the infamous show trials; the massacre of Trotskyists in the Vorkuta slave-labor camp; and the assassination by Stalinist agents of Leon Sedov, Trotsky's son, and other oppositionists outside the Soviet Union. It concludes with an examination of how the purges transformed the CPSU and Soviet society as a whole.
