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
The republican Reichsadler is based on the Reichsadler introduced by the Paulskirche Constitution of 1849, which was decided by the German National Assembly in Frankfurt upon Main, at the peak of the German civic movement demanding parliamentary participation and the unification of the German states. The achievements and signs of this movement had been mostly done away after its downfall and the political reaction in the 1850s. Only the tiny German Principality of Waldeck-Pyrmont upheld the tradition and continued to use the German colours called Schwarz-Rot-Gold in German ().
