How did the russia civil war finally end

The Russian Civil War was to tear Russia apart for three years - between 1918 and 1921. The civil war occurred because after November 1917, many groups had formed that opposed Lenin's Bolsheviks ... At the end of 1917, the Bolsheviks only effectively controlled Petrograd, Moscow and the territory between both cities and then came the rise of the USSR

The Red Army won this war because their army was better organised and they held the best territory.
