Answer:
Bolsheviks and Mensheviks.
Step-by-step explanation:
The Russian Social Democratic Party of Russia was initially the united political party that began as a revolutionary socialist party. Founded in Minsk to unite the various revolutionary factions in the country, the RSDLP became the uniting force for all political activities.
But this united stand wasn't to last long. On November 17, 1903, the party was divided with their differences in beliefs. The two factions that came out of the united party were referred to as the Bolsheviks (the majority) and the Mensheviks (minority). The Bolsheviks were led by Vladimir Lenin while Julius Martov led the Mensheviks.
