The Socialist Revolutionary Party, or Party of Socialist-Revolutionaries was a major political party in late Imperial Russia, and both phases of the Russian Revolution and early Soviet Russia. The party was established in 1902 out of the Northern Union of Socialist Revolutionaries (founded in 1896), bringing together many local socialist revolutionary groups established in the 1890s, notably the Workers' Party of Political Liberation of Russia created by Catherine Breshkovsky and Grigory Gershuni in 1899. The party's programme was democratic and socialist — it garnered much support among Russia's rural peasantry, who in particular supported their programme of land-socialization as opposed to the Bolshevik programme of land-nationalization—division of land into peasant tenants rather than collectivization into authoritarian state management.
