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.
Flag of Germany
From 1956 to 1964, West and East Germany attended the Winter and Summer Olympic Games as a single team, known as the United Team of Germany. After the East German national flag was changed in 1959, neither country accepted the flag of the other. As a compromise, a new flag was used by the United Team of Germany from 1960 to 1964, featuring the black-red-gold tricolour defaced with white Olympic rings in the red stripe. In 1968 the teams from the two German states entered separately, but both used the same German Olympic flag. From 1972 to 1988, the separate West and East German teams used their respective national flags.
