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.
Coat of arms of Germany
In 1815, a German Confederation ("Bund") of 39 loosely united German states was founded on the territory of the former Holy Roman Empire. Until 1848, the confederation did not have a coat of arms of its own. The Federal Diet ("Bundestag") meeting at Frankfurt am Main used a seal which carried the emblem of the Austrian Empire, since Austria had taken over the union's leadership. It showed a black, double-headed eagle, which Austria had adopted just before the dissolution of the Holy Roman Empire of the German Nation.
