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
An off-centred disk version of the swastika flag was used as the civil ensign on German-registered civilian ships and was used as the jack on (the name of the German Navy, 1933–1945) warships. The flags for use on sea had a through and through image, so the "left-facing" and "right-facing" version were each present on one side while the national flag was right-facing on both sides.
