The Siberian Army was an armed formation of socialist Russian troops that existed from June 1918 to July 1919 during the Russian Civil War. The army was formed by leaders of the Socialist Revolutionary Party who were opposed to the Bolsheviks under Vladimir Lenin, and the army fought against the Red Army. In November 1918, Alexander Kolchak took over Siberia, and the Siberian Army became the White Army's Eastern Front in July 1919.
