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.

In 1914 a series of drafts were made for proposed Coat of Arms and Flags for the German Colonies. However, World War I broke out before the designs were finished and implemented and the symbols were never actually taken into use. Following the defeat in the war, Germany lost all its colonies and the prepared coat of arms and flags were therefore never used.
