Political Parties in Russia (World Revolution)

Since the February Revolution, the Russian Democratic Federative Republic (or RDFR) has been a multiparty democracy and, since the October Spring, been a socialist or worker's state as enshrined by the constitution of 1921. Since 1918, Russia has been limited to only socialist parties (since the right wing elements had already rebelled against the government). Russia's head of state, the President, is elected by popular vote conducted every 2 or 3 years, though the soviets and zemstvos can vote to impeach the President at any time. The head of government is the premier, who is elected by the Constituent Assembly, which consists of elected representatives of the constituencies in Russia. These parties have been known to often frequently dissolve, split, or merge into other parties due to fluctuating national issues. Thus the political parties can be divided into different eras. Frequently, one party or coalition holds a somewhat small majority against another large party or coalition, though their have been eras where a single party has dominated for several decades, such as the Bolshevik-Leninist Party of Leon Trotsky or the Left Socialists under Victor Serge.

Revolutionary Era (1917-1921)
The Revolutionary Era is typically considered to have begun with the February Revolution and ended with the establishment of a Russian Constitution in 1921. This era was a period of great national turmoil that decided the direction that the nascent republic would go in. Nationalists on Russia's edges broke away while other areas were conquered by Imperial Germany and right wing elements within the new government, frustrated at the victory of the socialists, would stage a series of uprisings and coup attempts that would end in the establishment of a rival reactionary government in Vladivostok supported by Britain, the US, and Japan.

Socialist-Revolutionary Party
The Socialist Revolutionary Party, or Party of Socialists-Revolutionaries (the SRs or Esers; Russian: Партия социалистов-революционеров (ПСР), эсеры, esery) was a major political party in early 20th century Imperial Russia. After the October Spring, the SRs won a plurality of the national vote in Russia's first ever democratic elections and formed a coalition with the Bolsheviks, later known as the Russian Communist Party, and the Mensheviks, later known as the Social Democratic Labor Party, known as the Revolutionary Coalition. This coalition has the support of a wide range of socialist groups, as right as the Popular Socialists led by Kerensky and as left as the anarchist Pyotr Kropotkin, who served as minister of education in the Revolutionary Coalition Cabinet.
