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.
List of German flags
The flag with the "Hakenkreuz" and white disc centered was used throughout (1920–45) as the NSDAP party flag (). Between 1933 and 1935, it was used as the national flag () and merchant flag () - interchangeably with the black-white-red horizontal tricolour last used (up to 1918) by the German Empire. In 1935, the black-white-red horizontal tricolour was scrapped again, and the flag with the "off-center" "Hakenkreuz" and disc was instituted as the only national flag (and was to remain as such until 1945). The flag with the centered disc only continued to be used as the "Parteiflagge" after 1935.
