The Socialist Revolutionaries (SRs) were the largest political party in Russia in the crucial revolutionary year of 1917. Heirs to the legacy of the People’s Will movement, the SRs were unabashed proponents of peasant rebellion and revolutionary terror, emphasizing the socialist transformation of the countryside and a democratic system of government as their political goals. They offered a compelling, but still socialist, alternative to the Bolsheviks, yet by the early 1920s their party was shattered and its members were branded as enemies of the revolution. In 1922, the SR leaders became the first fellow socialists to be condemned by the Bolsheviks as “counter-revolutionaries” in the prototypical Soviet show trial. Scott B. Smith presents both a convincing account of the defeat of the SRs and a deeper analysis of the significance of the political dynamics of the Civil War for subsequent Soviet history. Smith reveals a complex and nuanced picture of the postrevolutionary struggle and demonstrates that the Civil War—and in particular the struggle with the SRs—was the formative experience of the Bolshevik party and the Soviet state. With extensive information on Fanya/Fania Kaplan, the female SR-member who tried to kill Lenin in August 1918 because of the betrayal of the revolution by the Bolsheviks.
