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.
National colours of Germany
When on 18 May 1848 the Frankfurt Parliament first convened, the city streets were decorated in the "German colours" like the assembly room in St. Paul's Church. On November 12, the parliament passed a resolution whereafter black-red-gold became the German war and merchant flag. However, as official flag of the German Confederation, the tricolour was mainly used in the small Imperial fleet (Reichsflotte), which was dissolved by 1852. The Frankfurt Constitution, adopted in 1849 and never carried into effect, omitted any provision of national symbols. After the dissolution of the Frankfurt Parliament, the tricolour vanished from public space. Mocked by Heinrich Heine as "old Germanic rubbish", it nevertheless remained the official flag of the German Confederation, "revitalized" in 1866 as the banner of Austria and her allies in the War with Prussia and the North German states.
