"To my mind, the most significant single scholarly contribution made to date, anywhere, to the history of Soviet power."—George F. KennanThis book forms the second volume of Tucker's biography of Stalin, the first volume of which was "Stalin as Revolutionary". The author shows that Stalin was a Bolshevik of the radical right whose revolution cast the country deep into its imperial, autocratic past. In 1929 Stalin plunged Soviet Russia into a coercive "revolution from above", a decade-long effort to amass military-industrial power for a new war. He forced 25 million peasant families into state-run collectives and transformed the Communist Party into a servile instrument. In 1939, he concluded the pact with Hitler that enabled him to grasp at Eastern Europe while Hitler made war in the West. Tucker brings a fresh analysis to these events and to the Terror of the 1930s, revealing the motives and methods of what he calls the greatest murder mystery of this century.
