Russian Social Democratic Labour Party
political party in the Russian Empire
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.
Despite repeated attempts at reunification, the rift between the Bolsheviks and Mensheviks widened, resulting in a formal split in 1912. The February Revolution of 1917 saw some Mensheviks support cooperation with the Provisional Government, which the Bolsheviks opposed in favor of "all power to the soviets". After the Bolsheviks seized power in the October Revolution later that year, the RSDLP was effectively dissolved. In 1918, the Bolshevik party formally renamed itself the Russian Communist Party (Bolsheviks), which later became the Communist Party of the Soviet Union.
History
Origins and early activities
The RSDLP was not the first Russian Marxist group; the Emancipation of Labour group had been formed in 1883. The RSDLP was created to oppose the revolutionary populism of the Narodniks, which was later represented by the Socialist Revolutionary Party (SRs).

Why this record matters
The subject matters to the history & society register because the source frames it as political party in the Russian Empire. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q204911. VIAF identifies the subject as 129605317. The Library of Congress control number is n82155150. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1898, 1903, 1905 and 1912.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
