Estonia

Estonia flag with blue, black and white horizontal bands

The Estonian flag has three equal horizontal bands: blue, black and white from top to bottom.

Its student origins go back to 1884, when the Estonian Students’ Society’s flag was consecrated at Otepää. The state flag law followed in 1922. Soviet occupation interrupted its official use in Estonia; the tricolor was restored as the state flag in 1990.

Botswana

The blue of the flag of Botswana is similar to sky blue. A broad black band crosses the middle, with a narrow white stripe along each edge.

The Botswana embassy’s explanation connects blue with sky and water, while black and white express racial harmony. Water has particular importance in the country’s dry climate.
