Mensheviks in the context of "Bolshevik"

The Russian Revolution was a period of political and social change in Russia, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a civil war. It can be seen as the precursor for other revolutions that occurred in the aftermath of World War I, such as the German Revolution of 1918–1919. The Russian Revolution was a key event of the 20th century.

The Russian Revolution was inaugurated with the February Revolution in 1917, in the midst of World War I. With the German Empire inflicting defeats on the front, and increasing logistical problems causing shortages of bread and grain, the Russian Army was losing morale, with large scale mutiny looming. Officials were convinced that if Tsar Nicholas II abdicated, the unrest would subside. Nicholas stepped down on 15 March [O.S. 2 March], ushering in a provisional government led by the Duma (parliament). During the unrest, Soviet councils were formed by locals in Petrograd (now Saint Petersburg) that initially did not oppose the new government; however, the Soviets insisted on their influence in the government and control over militias. By March, Russia had two rival governments. The Provisional Government held state power in military and international affairs, whereas the network of Soviets held domestic power. Critically, the Soviets held the allegiance of the working class, and urban middle class. There were mutinies, protests and strikes. Socialist and other leftist political organizations competed for influence within the Provisional Government and Soviets. Factions included the Mensheviks, Social Revolutionaries, Anarchists, and the Bolsheviks, a far-left party led by Vladimir Lenin.

Vladimir Ilyich Ulyanov (22 April [O.S. 10 April] 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He was the first head of government of Soviet Russia from 1917 until his death in 1924, and of the Soviet Union from 1922 until his death. As the founder of the Bolsheviks, Lenin led the October Revolution, which established the world's first communist state. His government won the Russian Civil War and created a one-party state under the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism.

Lenin embraced revolutionary socialist politics after his brother was executed in 1887 for plotting to assassinate the Russian tsar. He was expelled from Kazan Imperial University for participating in student protests, and earned a law degree before moving to Saint Petersburg in 1893 and becoming a prominent Marxist activist. In 1897, Lenin was exiled to Siberia for three years, after which he moved to Western Europe and became a leading figure in the Russian Social Democratic Labour Party. In 1903, the party split between Lenin's Bolshevik faction and the Mensheviks, with Lenin advocating for a vanguard party to lead the proletariat in establishing socialism. Lenin briefly returned to Russia during the Revolution of 1905. During the First World War he campaigned for its transformation into a Europe-wide proletarian revolution. After the February Revolution of 1917 ousted Tsar Nicholas II, Lenin returned to Russia and played a leading role in the October Revolution.

The Russian Social Democratic Labour Party (RSDLP), also known as the Russian Social Democratic Workers' Party (RSDWP) or the Russian Social Democratic Party (RSDP), was a socialist political party founded in 1898 in Minsk, Russian Empire. The party emerged from the merger of various Marxist groups operating under Tsarist repression, and was dedicated to the overthrow of the autocracy and the establishment of a socialist state based on the revolutionary leadership of the Russian proletariat.

The RSDLP's formative years were marked by ideological and strategic disputes culminating at its Second Congress in 1903, where the party split into two main factions: the Bolsheviks, led by Vladimir Lenin, who advocated a tightly organized vanguard of professional revolutionaries; and the Mensheviks, led by Julius Martov and others, who favored a more moderate, broad-based model. During and in the years after the 1905 Revolution, the RSDLP operated both legally and underground, publishing newspapers, infiltrating trade unions, and agitating among industrial workers.

The Communist Party of the Soviet Union (CPSU), at some points known as the Russian Communist Party (Bolsheviks) and the All-Union Communist Party (Bolsheviks), and sometimes referred to as the Bolshevik Party and Soviet Communist Party, was the founding and ruling political party of the Soviet Union. The CPSU was the sole governing party of the Soviet Union until 1990 when the Congress of People's Deputies modified Article 6 of the 1977 Soviet Constitution, which had previously granted the CPSU a monopoly over the political system. The party's main ideology was Marxism–Leninism. The party was outlawed under Russian president Boris Yeltsin's decree on 6 November 1991, citing the 1991 Soviet coup attempt as a reason.

The party started in 1898 as part of the Russian Social Democratic Labour Party (RSDLP). In 1903, that party split into a Menshevik (m) ("minority") and Bolshevik (b) ("majority") faction; the latter, led by Vladimir Lenin, is the direct ancestor of the CPSU and is the party that seized power in the October Revolution of 1917. Its activities were suspended on Soviet territory 74 years later, on 29 August 1991, soon after a failed coup d'état by conservative CPSU leaders against the reforming Soviet president and party general secretary Mikhail Gorbachev.

Georgi Valentinovich Plekhanov (Russian: Георгий Валентинович Плеханов [ɡʲɪˈorɡʲɪj vəlʲɪnʲˈtʲinəvʲɪtɕ plʲɪˈxanəf] ; 11 December [O.S. 29 November] 1856 – 30 May 1918) was a Russian Marxist theorist, philosopher, and revolutionary. After beginning his revolutionary career as a populist, in 1883 Plekhanov established the Emancipation of Labour group, the first Russian Marxist political organisation. He is widely regarded as the "father of Russian Marxism", and his theoretical works were instrumental in converting a generation of revolutionaries, including Vladimir Lenin, to the cause.

Plekhanov was a prominent leader in the Russian Social Democratic Labour Party (RSDLP) and the Second International. In 1900, he collaborated with Lenin in founding the party newspaper Iskra, and at the party's Second Congress in 1903, initially sided with Lenin's Bolshevik faction. However, he soon broke with the Bolsheviks over their organisational principles, which he criticised as overly centralist, and became a leading figure in the opposing Menshevik faction. During the 1905 Russian Revolution, Plekhanov maintained that Russia was only ready for a bourgeois-democratic revolution and argued against what he saw as premature attempts to seize power by the proletariat.
