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.

In 1841, the German linguist and poet August Heinrich Hoffmann von Fallersleben wrote the lyrics of "" as a new text for that music, counterposing the national unification of Germany to the eulogy of a monarch, lyrics that were considered revolutionary at the time. Along with the flag of Germany, which first appeared in its essentially "modern" form in 1778; it was one of the symbols of the March Revolution of 1848.
