Abstract:In April, 1917, Lenin held that the democratic revolution of overthrowing Tsarist autocracy had completed and the bourgeoisie had been in power, which meant that Russian revolution was to march into the “second stage”, namely, the power should be transferred to the proletariat and poor peasants. Nevertheless, Kamenev believed that Russia's bourgeois revolution had not completed and it was unwise to overthrow the bourgeois provisional government. In October, Lenin pointed out that the Petrograd Soviet and Moscow Soviet had turned to the Bolshevik so the Party was ready and must lead an armed uprising and seize control of government. In contrast, Kamenev was opposed to armed uprising, especially before the second congress of the Soviet. History proves that Kamenev is wrong because his idea goes against the rule of revolutionary struggles.
