Imperialist capitalism has become the eve of socialist revolution owing to the level of its development, the contradictions it has aggravated and the decay it has experienced. The internationalisation of productive forces, highly advanced socialization of production and enormous accumulation of wealth, have matured the conditions for proletarian revolution and socialism worldwide. The solution of this epoch determining contradiction between capitalism and socialism has entered the agenda of history. The victory of Great Socialist October Revolution inaugurated the age of proletarian revolutions, the age of transition from capitalism to socialism on a global scale. This new age found its explicit expression in the chain of revolutions covering the greater part of the 20th century and the processes of socialist construction.
