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
After World War II, Germany was occupied and divided. Both new states founded in 1949, the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany), took up the "democratic" colours of black, red, and gold again, with the GDR adding their own socialist symbols to their flag in 1959. As a compromise, the Olympic United Team of Germany, which had first competed in 1956, had to add white Olympic rings to the flag for the games of 1960 and 1964, and also for 1968 when two separate German teams entered under common symbols. After the fall of the Berlin Wall in 1989, East German citizens cut out the socialist symbols of the East German flag in order to show support for a unification with West Germany, which had also continued the use of the traditional eagle coat of arms, called "Bundesadler".
