Flag of Germany
With the formation of the short-lived Weimar Republic after World War I, the tricolour was adopted as the national flag of Germany. Sixteen years later following World War II, the tricolour was again designated as the flag of both West and East Germany divided states in 1949. The two flags were identical until 1959, when the East German flag was augmented with the coat of arms of East Germany. Since reunification on 3 October 1990, the black-red-gold tricolour has become the flag of a reunified Federal Republic of Germany.
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.
