The Russian Revolution from 1815-1924 saw a period of civil war from 1918-1921. Key events included the formation of the Czech Legion that opposed Bolshevik rule and helped spark the civil war. The Bolsheviks instituted a policy of "War Communism" from 1918-1921 that involved the nationalization of industry and establishment of a state-controlled economy. This policy included forced grain requisitions from peasants and attempts to collectivize agriculture, sparking conflict between the Bolsheviks and peasants. The civil war period was one of violence and turmoil as the Bolsheviks consolidated control over Russia.
