The modern sovereign state of Estonia was born on 24 February 1918, when the Estonian Declaration of Independence (Manifest Eestile) was publicly read in Tallinn (Reval), ending centuries of Danish, German, Swedish, and Russian rule.
Independence required winning the Estonian War of Independence (1918–1920) against Soviet Russia and German Baltische Landeswehr. The 1920 Treaty of Tartu recognized Estonia's sovereignty de jure.
Estonia celebrates 24 February as its National Day (Independence Day), commemorating the 1918 declaration as the foundational moment of modern Estonian statehood.
