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
Upon the Nazi Party's "Machtergreifung" when Adolf Hitler came to power in January 1933, the "democratic" colours quickly fell out of use, though they were not officially abolished. By order of March 7, two days after the German federal election, Reich President Paul von Hindenburg re-introduced black, white, and red as official decorations on the coming "Volkstrauertag" public holiday. Alongside the swastika flag of the Nazi Party, the imperial colours were restored as a provisional national symbol, subject to a final decision by the German government. The concurrent Nazi flag also used a combination of black, white, and red colours, but not in the same way as the old flag of the German Empire. Instead, the socialist red was the dominant colour.
