Menshevik

The Mensheviks (sometimes called Menshevists Russian: меньшевик) were a faction of the Russian socialist movement that emerged in 1904 after a dispute in the Russian Social Democratic Labour Party (RSDLP) between Julius Martov and Vladimir Lenin, leading to the party splitting into two factions, one being the Mensheviks and the other being the Bolsheviks. The dispute originated at the Second Congress of the RSDLP, ostensibly over minor issues of party organization. Martov's supporters, who were in the minority in a crucial vote on the question of party membership, came to be called Mensheviks, derived from the Russian word меньшинство (minority), whereas Lenin's adherents were known as Bolsheviks, from большинство (majority). Neither side held a consistent majority over the course of the congress. The split proved to be long-standing and had to do both with pragmatic issues based in history, such as the failed revolution of 1905, and theoretical issues of class leadership, class alliances, and interpretations of historical materialism. While both factions believed that a proletariat revolution was necessary, the Mensheviks generally tended to be more moderate and were more positive towards the liberal opposition and the dominant peasant-based Socialist Revolutionary party.

At the 2nd Congress of the RSDLP in August 1903, Lenin and Martov disagreed, first about which persons should be in the editorial committee of the party newspaper Iskra, and then about the definition of a "party member" in the future party statute. Lenin's formulation required the party member to be a member of one of the party's organizations, whereas Martov's only stated that he should work under the guidance of a party organization. Although the difference in definitions was small, with Lenin's being slightly more exclusive, it was indicative of what became an essential difference between the philosophies of the two emerging factions: Lenin argued for a small party of professional revolutionaries with a large fringe of non-party sympathizers and supporters, whereas Martov believed it was better to have a large party of activists with broad representation.
