Bolshevism itself now expends considerable effort in its endeavours to make the influence of the lower classes felt, not only in social work but in political activities as well, and their endeavours have been extraordinarily effective in the most varied directions. The supreme power of the proletariate under communistic guidance means, then, first and foremost, that the non-Party proletariate are completely shut out from all participation in political or social work. When the Russian Social Democratic Party in the beginning of 1900 split and divided into a majority of Russian Bolshevists and a minority of Menshevists, one of the disputed points that led to the break was how a revolutionary party should be organized in Russia at that time. The Communist Party is called the proletariate's advance-guard, and its picture, as a whole, shows it to be an attacking party, marching in the van of the revolution.
