There were 37 sessions and 51 delegates. Of these, 33 supported
Iskra, the party newspaper (controlled by Lenin and his close allies), 5 backed the
Bund and there were 2 "
economists" (Marxists who believed workers should concentrate on economic demands rather than political ones). 6 delegates were neutral. According to historian Richard Cavendish, the delegates originally "assembled in a flea-ridden flour warehouse in Brussels", where they elected
Georgi Plekhanov as chair. During the fifteenth session the delegates voted in favor of supporting a
dictatorship of the proletariat as it approved into the party programme the paragraph "A necessary condition for this social revolution is the dictatorship of the proletariat, that is, conquest by the proletariat of such political power as will enable it to suppress any resistance by the exploiters.". The Congress saw the RSDLP split into
Bolsheviks and
Mensheviks as a result of a dispute between Lenin and
Julius Martov over the major points of the Party Programme. At the 22nd session, Lenin and Martov disagreed on the wording of the first party rule defining membership. Lenin proposed a party member should be someone "Who recognizes the party's program and supports it by material means and by
personal participation in one of the party organisations". Martov's wording was slightly different: "
regular personal association under the direction of one of the party organisations". The dispute was about whether the party should have a loose membership or whether it should be a party of professional revolutionaries. Plekhanov, founder of Russian Marxism, supported Lenin.
Leon Trotsky, future leader of the Petrograd Soviet, backed Martov. The congress voted 28–23 in Martov's favour but his support included the 7 Bundists and Economists who would later walk out from the congress. This left Lenin's faction in the majority, so Lenin called his faction the
Bolsheviks or majoritarians. Martov accepted this, calling his faction the
Mensheviks or minoritarians. At the 27th session, one of the constituent groups of the party, the
General Jewish Labour Bund, asked that the Bund would be recognized as the sole representative of the Jewish working class in Russia. A
Bundist delegate tabled a motion that all Russian citizens should have the right to use their own language. Lenin and the
Iskra group opposed the motion. It was defeated in a tie, 23 votes against 23 votes. However, a similar motion proposed by
Noe Zhordania (leader of the
Transcaucasian Social Democrats) was passed. The two economists also walked out when the congress decided that the Iskraists should represent the party abroad. The
2nd Central Committee was elected at the congress.
Iskra's editorial board became the party's Central Organ and was cut from six to three members (Lenin, Plekhanov and Martov). According to Cavendish, the day after the congress ended, Lenin, who knew London well, took some of the delegates to the
Natural History Museum and
London Zoo, "followed by a respectful visit to
Karl Marx’s grave in
Highgate Cemetery. == References ==
