In What Is to Be Done?, Lenin argues that the working class will not spontaneously become political simply by fighting economic battles with employers over wages, working hours and the like. To convert the working class to Marxism, Lenin insists that Marxists should form a political party, or "vanguard", of dedicated revolutionaries to spread Marxist political ideas among the workers. The pamphlet precipitated in part the split of the Russian Social Democratic Labor Party (RSDLP) between Lenin's Bolsheviks and the Mensheviks.[2]
