Socialist Revolutionary Party

The Socialist Revolutionary Party, also Party of Socialist-Revolutionaries or Social Revolutionary Party (the SRs, , or Esers, ; , ), was a major political party in late Imperial Russia, during both phases of the Russian Revolution, and in early Soviet Russia. The SRs were agrarian socialists and supporters of a democratic socialist Russian republic. The ideological heirs of the Narodniks, the SRs won a mass following among the Russian peasantry by endorsing the overthrow of the Tsar and the redistribution of land to the peasants. The SRs boycotted the elections to the First Duma following the Revolution of 1905 alongside the Russian Social Democratic Labour Party, but chose to run in the elections to the Second Duma and received the majority of the few seats allotted to the peasantry. Following the 1907 coup, the SRs boycotted all subsequent Dumas until the fall of the Tsar in the February Revolution of March 1917. Controversially, the party leadership endorsed the Russian Provisional Government and participated in multiple coalitions with liberal and social-democratic parties, while a radical faction within the SRs rejected the Provisional Government's authority in favor of the Congress of Soviets and began to drift towards the Bolsheviks. These divisions would ultimately result in the party splitting over the course of the summer of 1917 into the Right and Left SRs. Meanwhile, Alexander Kerensky, one of the leaders of the February Revolution and the second and last head of the Provisional Government (July–November 1917) was a nominal member of the SR party but in practice acted independently of its decisions. By November 1917, the Provisional Government had been widely discredited by its failure to withdraw from World War I, implement land reform or convene a Constituent Assembly to draft a Constitution, leaving the soviet councils in de facto control of the country. The Bolsheviks thus moved to hand power to the 2nd Congress of Soviets in the October Revolution. After a few weeks of deliberation, the Left SRs ultimately formed a coalition government with the Bolsheviks – the Council of People's Commissioners – from November 1917 to March 1918 while the Right SRs boycotted the Soviets and denounced the Revolution as an illegal coup. The SRs obtained a majority in the subsequent elections to the Russian Constituent Assembly, with most of the party's seats going to the Right faction.
