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.
National colours of Germany
The national colours of the Federal Republic of Germany are officially black, red, and gold, defined with the adoption of the West German flag as a tricolour with these colours in 1949. As Germany was divided into West Germany and East Germany beginning in 1949 and continuing through 1990, both Germanies retained the black, red, and gold colors on each respective flag. After German reunification in 1990, West and East Germany adopted the West German flag as the flag of the reunited Germany, therefore maintaining black, red, and gold as Germany's colors.
