Flag of Germany
With the formation of the short-lived Weimar Republic after World War I, the tricolour was adopted as the national flag of Germany. Sixteen years later following World War II, the tricolour was again designated as the flag of both West and East Germany divided states in 1949. The two flags were identical until 1959, when the East German flag was augmented with the coat of arms of East Germany. Since reunification on 3 October 1990, the black-red-gold tricolour has become the flag of a reunified Federal Republic of Germany.
National colours of Germany
When on 18 May 1848 the Frankfurt Parliament first convened, the city streets were decorated in the "German colours" like the assembly room in St. Paul's Church. On November 12, the parliament passed a resolution whereafter black-red-gold became the German war and merchant flag. However, as official flag of the German Confederation, the tricolour was mainly used in the small Imperial fleet (Reichsflotte), which was dissolved by 1852. The Frankfurt Constitution, adopted in 1849 and never carried into effect, omitted any provision of national symbols. After the dissolution of the Frankfurt Parliament, the tricolour vanished from public space. Mocked by Heinrich Heine as "old Germanic rubbish", it nevertheless remained the official flag of the German Confederation, "revitalized" in 1866 as the banner of Austria and her allies in the War with Prussia and the North German states.
