The document discusses the Russian Civil War that took place after the Bolshevik Revolution in Russia from 1917-1922. It provides background information on key terms, events, and figures involved in the civil war. It then examines the impact of the Treaty of Brest-Litovsk signed in 1918, which required Russia to cede significant territory and resources to the German Empire, contributing to economic and political instability in Russia and opposition to the Bolshevik government. This further exacerbated other ongoing issues including foreign intervention, opposition to Bolshevik rule, and food shortages, leading to escalating conflict between the Bolshevik Red Army and opposing White forces.
