Despite a number of attempts at reunification, the split proved permanent. As time passed, ideological differences emerged in addition to the original organizational differences. The main difference that emerged in the years after 1903 was that the Bolsheviks believed that only the workers, backed up by the peasantry, could carry out the bourgeois-democratic revolutionary tasks in Russia, which would then provide incentive to socialist revolution in Germany, France and Britain, while the Mensheviks believed that the workers and peasants must seek out enlightened people from the liberal bourgeoisie to carry out the bourgeois-democratic revolutionary tasks in Russia. The two warring factions both agreed that the coming revolution would be "bourgeois-democratic" within Russia, but while the Mensheviks viewed the liberals as the main ally in this task, the Bolsheviks opted for an alliance with the peasantry as the only way to carry out the bourgeois-democratic revolutionary tasks while defending the interests of the working class. Essentially, the difference was that the Bolsheviks considered that in Russia the tasks of the bourgeois democratic revolution would have to be carried out without the participation of the bourgeoisie. The 3rd Party Congress was held separately by the Bolsheviks.
