 At the conference, a schism emerged between Lenin's supporters and those of Julius Martov.Martov argued that party members should be able to express themselves independently of the party leadership; Lenin disagreed, emphasising the need for a strong leadership with complete control over the party.Lenin's supporters were in the majority, and Lenin termed them the "majoritarians" ("bol'sheviki" in Russian; thus Bolsheviks); in response, Martov termed his followers the "minoritarians" ("men'sheviki" in Russian; thus Mensheviks).
