Bolsheviks

The Bolsheviks, led by Vladimir Lenin, were a radical faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the Second Party Congress in 1903. The Bolshevik party, formally established in 1912, seized power in Russia in the October Revolution of 1917 and was later renamed the Russian Communist Party, All-Union Communist Party, and ultimately the Communist Party of the Soviet Union. Its ideology, based on Leninist and later Marxist–Leninist principles, became known as Bolshevism.

The origin of the RSDLP split was Lenin's support for a smaller party of professional revolutionaries, as opposed to the Menshevik desire for a broad party membership. The influence of the factions fluctuated in the years up to 1912, when the RSDLP formally split in two. The political philosophy of the Bolsheviks was based on the Leninist principles of vanguardism and democratic centralism. Lenin was also more willing to use illegal means such as robbery to fund the party's activities. By 1917, influenced by the experiences of World War I, he reached the conclusion that the chain of world capitalism could "break at its weakest link" in Russia before it assumed the level of the advanced countries, opposing theorists such as Georgi Plekhanov. Lenin had also come to view poorer peasants as potential allies of the relatively small Russian proletariat.

After the February Revolution of 1917, Lenin returned to Russia and issued his April Theses, which called for "no support for the Provisional Government" and "all power to the soviets." During the summer of 1917, which saw events including the July Days and Kornilov affair, large numbers of radicalized workers joined the Bolsheviks, which planned the October Revolution that overthrew the government. The Bolsheviks initially governed in coalition with the Left Socialist-Revolutionaries, but increasingly centralized power and suppressed opposition during the Russian Civil War. After 1921, it became the sole legal party in Soviet Russia and the Soviet Union. Under Joseph Stalin's leadership, Bolshevism became linked to his policies of "socialism in one country," rapid industrialization, collectivized agriculture, and centralized state control.

Lenin's political pamphlet What Is to Be Done?, written in 1901, helped to precipitate the Bolsheviks' split from the Mensheviks. In Germany, the book was published in 1902, but in Russia, strict censorship outlawed its publication and distribution. One of the main points of Lenin's writing was that a revolution can only be achieved by a strong, professional leadership with deep dedication to Marxist theoretical principles and an organization that spanned through the whole of Russia, abandoning what Lenin called "artisanal work" towards a more organized revolutionary work. After the proposed revolution had successfully overthrown the Russian autocracy, this strong leadership would relinquish power and allow a Socialist party to fully develop within the principles of democratic centralism. Lenin said that if professional revolutionaries did not maintain influence over the fight of the workers, then that fight would steer away from the party's objective and carry on under the influence of opposing beliefs or even away from revolution entirely.

The pamphlet also showed that Lenin's view of a socialist intelligentsia was in line with Marxist theory. For example, Lenin agreed with the Marxist ideal of social classes ceasing to be and for the eventual "withering away of the state". Most party members considered unequal treatment of workers immoral and were loyal to the idea of a completely classless society. This pamphlet also showed that Lenin opposed another group of reformers, known as "Economists", who were for economic reform while leaving the government relatively unchanged and who, in Lenin's view, failed to recognize the importance of uniting the working population behind the party's cause.

At the 2nd Congress of the RSDLP, which was held in Brussels and then London during August 1903, Lenin and Julius Martov disagreed over the party membership rules. Lenin, who was supported by Georgy Plekhanov, wanted to limit membership to those who supported the party full-time and worked in complete obedience to the elected party leadership. Martov wanted to extend membership to anyone "who recognises the Party Programme and supports it by material means and by regular personal assistance under the direction of one of the party's organisations." Lenin believed his plan would develop a core group of professional revolutionaries who would devote their full time and energy towards developing the party into an organization capable of leading a successful proletarian revolution against the Tsarist autocracy.

The base of active and experienced members would be the recruiting ground for this professional core. Sympathizers would be left outside and the party would be organised based on the concept of democratic centralism. Martov, until then a close friend of Lenin, agreed with him that the core of the party should consist of professional revolutionaries, but he argued that party membership should be open to sympathizers, revolutionary workers, and other fellow travellers. The two had disagreed on the issue as early as March–May 1903, but it was not until the Congress that their differences became irreconcilable and split the party. At first, the disagreement appeared to be minor and inspired by personal conflicts. For example, Lenin's insistence on dropping less active editorial board members from Iskra or Martov's support for the Organizing Committee of the Congress which Lenin opposed. The differences grew and the split became irreparable.

Internal unrest also arose over the political structure that was best suited for Soviet power. As discussed in What Is To Be Done?, Lenin firmly believed that a rigid political structure was needed to effectively initiate a formal revolution. This idea was met with opposition from once close allies, including Martov, Plekhanov, Vera Zasulich, Leon Trotsky, and Pavel Axelrod.^{[page needed]} Plekhanov and Lenin's major dispute arose addressing the topic of nationalizing land or leaving it for private use. Lenin wanted to nationalize to aid in collectivization, whereas Plekhanov thought worker motivation would remain higher if individuals were able to maintain their own property. Those who opposed Lenin and wanted to continue on the socialist mode of production path towards complete socialism and disagreed with his strict party membership guidelines became known as "softs" while Lenin supporters became known as "hards".
