The Agrarian Policy of the Russian Socialist-Revolutionary Party: From Its Origins Through the Revolution of 1905-1907The Socialist Revolutionary (SR) party gained an overall majority in the election to the Russian Constituent Assembly, which was dissolved by the Bolsheviks in January 1918. The SRs derived the bulk of their electoral support from the peasantry, and the gulf between the predominantly urban Bolshevik party and the rural masses was to create immense problems for the Soviet government in the 1920s, culminating in the horrors of forced collectivization.
