Before the Revolution, despite supporting political reform (including Bolsheviks elected to the Duma, when opportune), Lenin proposed that capitalism could ultimately only be overthrown with revolution, not with gradual reforms—from within (Fabianism) and from without (social democracy)—which would fail, because the ruling capitalist social class, who hold economic power (the means of production), determine the nature of political power in a bourgeois society.[10] As epitomised in the slogan, "For a Democratic Dictatorship of the Proletariat and Peasantry", a revolution in underdeveloped Tsarist Russia required an allied proletariat of town and country (urban workers and peasants), because the urban workers would be too few to successfully assume power in the cities on their own. Moreover, owing to the middle-class aspirations of much of the peasantry, Leon Trotsky proposed that the proletariat should lead the revolution, as the only way for it to be truly socialist and democratic; although Lenin initially disagreed with Trotsky's formulation, he adopted it before the Russian Revolution in October 1917.
