Only after World War I, with Russia in revolutionary wreckage, was Estonia able to declare its independence. Shortly before World War II, in 1940, that independence was usurped by the Soviets, who—save for a brief three-year occupation by Hitler's Nazis—proceeded to suppress all forms of national Estonian pride for the next 50 years. Estonia finally regained independence in 1991. In the early 1990s, Estonia's own Riigikogu (Parliament), not some other nation's puppet ruler, handed down from the Upper City reforms that forced Estonia to blaze its post-Soviet trail to the European Union. Estonia has been a member of the EU since 2004, and in 2011, the country and its growing economy joined the Eurozone. Tallinn was also named the European City of Culture in 2011, cementing its growing reputation as a cultural hot spot.
