Flag of Germany
While the use of black-red-gold had been suggested in the Soviet zone in 1946, the Second People's Congress in 1948 decided to adopt the old black-white-red tricolour as a national flag for East Germany. This choice was based on the use of these colours by the National Committee for a Free Germany, a German anti-Nazi organisation that operated in the Soviet Union in the last two years of the war. In 1949, following a suggestion from Friedrich Ebert, Jr., the black-red-gold tricolour was instead selected as the flag of the German Democratic Republic upon the formation of this state on 7 October 1949. From 1949 to 1959, the flags of both West and East Germany were identical. On 1 October 1959, the East German government changed its flag with the addition of its coat of arms. In West Germany, these changes were seen as a deliberate attempt to divide the two Germanys. Displaying this flag in West Germany and West Berlin—where it became known as the (divider-flag)—was seen as a breach of the constitution and subsequently banned until the late 1960s.
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.
