sinimustvalge

Officially adopted as the national flag on this day in 1922 after the country declared its independence in 1918 in the short interlude between the retreat of the Bolsheviks and German occupation just before the end of World War I, the tricolour of Estonia was banned in August of 1940 with its annexation by the Soviet Union, though used continuously by the government-in-exile based in Stockholm and Estonian diaspora groups continuously from 1940 to 1991. The three equal bands of blue black and white (as referenced in the title) represent the landscape of the Baltic nation and was readopted in August of 1990 with the restoration of the republic.
