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 Saxony
The civil bicolour flag of white over green was used before World War II, and formally abolished in 1935, under the reforms of the Third Reich. It was readopted 1945 when Saxony became a state again, and abolished 1952 under governing reforms of the German Democratic Republic. When Germany was reunited, Saxony became a state again, and so the flag was finally officially readopted in 1991, having been a much used symbol during the demonstrations in the German Democratic Republic in 1989/90.
