When the Bolsheviks seized power in October 1917 they took control of Petrograd, with Moscow falling a few weeks later. However gaining control of the rest of the country was to prove a more difficult task. They faced external and internal threats, which were linked, and posed a serious danger to the very survival of the revolution. At the beginning of 1918 three particularly urgent questions confronted the new regime. First – how were the Bolsheviks, in view of their meagre military resources, to extend their control over the nation at large? Second – how could they achieve a speedy end to the war and effect a rapid withdrawal of the German army, which was currently occupying the greater part of Western Russia? Third – how quickly, if at all, would they be able to bring economic stability to a Russia devastated by four years of war and internal upheaval?The internal threat for the Bolsheviks was mainly from the left, other socialist groups such as the Mensheviks and the Social Revolutionaries, who were demanding a say in the new government. Thus in keeping with a promise he made to the Proletariat before the revolution, Lenin called the Constituent Assembly. However at the first elections, as Lenin had predicted the Bolsheviks were heavily outnumbered with the Social Revolutionaries gaining 410 seats and the Bolsheviks managing just 175. To use the Assembly, as a national government would pose a threat to continued Bolshevik rule, therefore the first step Lenin took was to dissolve the Assembly and condemn it as an instrument of the bourgeoisie. In place of the Assembly, Lenin use the All-Russian Congress of Soviets as an instrument of popular support, a body which of course the Bolsheviks had much more control and thus the first steps to consolidation of power was taken. However in doing this Lenin caused a great number of people to be aggrieved, especially the Mensheviks and Social Revolutionaries and thus with an impending Civil War, Lenin had to remove the external threat, so to concentrate on the internal one and hence the two are linked.The external threat was that of Germany and her allies in the First World War. The Russian army was disintegrating, morale plummeted, and they were in no fit state to carry on with the fighting. Lenin’s pragmatism shone through and realised that Bolshevik consolidation would be extremely difficult to achieve whilst the war was raging on. He did not want the Bolsheviks to suffer the same fate as the Provisional Government and so needed to end Russian involvement in the First World War quickly. Peace was made in the Treaty of Brest Litovsk 1918, which cost Russia vast expanses of her territory including Lithuania, Estonia, Latvia, Finland and the Ukraine. This represented around 32% of Russia’s agricultural land, 34% of its population and 54% of its industry, thus causing huge resentment within Russia. However knowing that the Bolsheviks were soon to face an internal Civil War, Lenin knew he must end this war, so to save resources which will prove to be vital in the consolidation of their power during the Civil War.After inheriting huge economic problems in 1917, Lenin had to adopt for again a pragmatic approach, even though the Revolution marked a victory of proletarian socialism over bourgeoisie capitalism. Therefore a transitional period was needed wear the Bolsheviks would work within the current framework, until such a time as socialism could be introduced, this was known as State Capitalism. The new regime simply did not possess enough power to impose sweeping, revolutionary economic policy and thus if they wanted to say in power for the short term at least, capitalism had to stay.Although Lenin considered the future was with the workers, if Russia could not feed herself then she would make no advances and thus logic demanded that in the Bolshevik treatment of the peasants the primary consideration must be how best they could be induced or forced into becoming suppliers of adequate quantities of food. Therefore in 1917 the Decree on Land and the Decree on Worker’s Control were brought in, to first of all please the mass of the population so the Bolsheviks power would be consolidated and secondly making agriculture and industry more efficient by legitimising practices that had been around since February, for example factories run by the workers.Therefore in conclusion the Bolsheviks faced several problems that seriously jeopardised the revolution, however in Lenin’s pragmatism we find the most important reason why they survived because it was his steps, most importantly getting Russia out of World War One, by signing the Treaty of Brest Litovsk, as it allowed them to concentrate on internal distractions, which helped the Bolsheviks to survive their first year and consolidate their power for future years to come.
