Examine and explain one force leading to the establishment and/or building of the new Soviet state under Lenin and later Stalin.

There were several pre-existing conditions in Russia favorable to the development of the Soviet state. I'll examine one of them: the absence of any real tradition in Russia of local government.
Russia was different from the Western European states in that feudalism did not exist in Russia in the Middle Ages. Feudalism in the Western countries, in which local barons were relatively autonomous, became the basis for the much later local municipalities that were a counter weight to the central power of the monarchy. Among the nations of Europe the process of power sharing occurred earliest in England with the signing of the Magna Carta in 1215. This led to English democracy and freedom, which developed much more slowly in the other countries.
In Russia this state of affairs had never really developed. Centralized power was more or less absolute in each stage of history from Tatar control through the period of the Czars. When the Czarist regime and then the following provisional government collapsed, there was a complete power vacuum because there were no localised municipal governments who could take charge. The Bolsheviks took over by default, since they were the only party ruthless enough and organized enough to seize power. With outside funding from the German government with whom Lenin had made an agreement that he would pull Russia out of the Great War, the Bolsheviks took over the country. The Russian population, lacking any democratic tradition or local government, was passive and resigned. There was little loyalty on their part to the Russian ancien régime or to the White Armies that fought to restore it. The Soviets were well organized and funded, and within a few years all opposition to them had been crushed.
