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 East Germany
Since the GDR had not yet been recognized under international law, it started to be in 1968 in sporting contests, such as in Olympic Games, teams with athletes from both parts of Germany. The Olympic Committee of the GDR refused to compete under the flag of the Federal Republic, and the Olympic Committee of Germany lasted until the very last moment on, no changes in the black-red-gold flag carry. Ultimately yet succeeded yet an agreement. They sat on the red stripes of black, red and gold flag of the Olympic rings in white. As part of the international recognition of the GDR by the United Nations and the recognition of the sovereignty of the GDR by the FRG, two separate teams with two separate flags took part since the 1972 Winter Olympics.
