The author considers the fact that in the years of the First World War, contrary to the old view, the struggle was not only for the new territories, but also for the establishment of the «eternal» peace of the world. Being an active participant in this struggle, the Bolsheviks defended the «socialist» model of the world in the ideological confrontation, mainly, with the adherents of the «democratic» model, which included not only liberals, but also many representatives of the international social democratic movement. However, in recent years this activity of the Bolsheviks is often ignored, it helps to wrench the picture of past and to one-side explanation of the world wars history.
