The Russian Social Democratic Labour Party (RSDLP) was a revolutionary political party founded in 1898 that aimed to represent the interests of the working class and promote socialist ideals in Russia. It emerged during a period of social upheaval, influenced by Marxist ideology, and played a crucial role in the political landscape leading up to the Russian Revolution of 1917. The RSDLP split into two factions, the Bolsheviks and the Mensheviks, which had differing views on how to achieve socialist goals.
