I think that one of the most critical developments that took place in Russia after the 7 November Revolution 1917 (Gregorian New Style calendar) was the Civil War between the Bolshevik "Reds" and the "Whites" of the Provisional Government. The Civil War that engulfed Russia for another three years after the November Revolution helped to plunge Russia into even more social, economic, and political disarray. Thousands of people died and millions more suffered greatly with the Civil War that resulted after the Bolsheviks took office.
This impacted the development of Russia. Russia would have to endure much more hardship before any hope of political stability could be evident. Given the fact that Marxist theories of change were not going to be as applicable in an agrarian and non- industrialized nation like Russia, the Civil War that ensued made the transition to the socialist- style economy even more difficult. The vast amount of dead also resulted in millions of orphans, children whose parents were killed or whose parents discarded them. The transition between the Czar's government, the Provisional Government, and the Bolshevik leadership contributed to this displacement that would impact Russia's growth and development in a significant manner.
