The Estonian War of Independence (Estonian: Vabadussõda, literally "Freedom War"), also known as the Estonian Liberation War, was a defensive campaign of the Estonian Army and its allies, most notably the White Russian Northwestern Army, Latvia, and the United Kingdom, against the Soviet Western Front offensive and the aggression of the Baltische Landeswehr. It was fought in connection with the Russian Civil War during 1918–1920. The campaign was the struggle of Estonia for its sovereignty in the aftermath of World War I. It resulted in a victory for the newly established state and was concluded in the Treaty of Tartu.
