Germany Flag Lapel Pin

When Germany was unified at the end of the 19th century, the national flag had stripes of black-white-red. After the defeat of the Second Reich in World War I, that flag was replaced by the black-red-yellow under the Weimar Republic. The Federal Republic of Germany (West Germany) restored the old black-red-yellow flag on May 9, 1949, and the government made use of a similar flag with the eagle shield in the centre.
 
The plain tricolour was also used in the communist-dominated German Democratic Republic (GDR; East Germany), although its coat of arms was added to the tricolour in 1959. The GDR flag disappeared in 1990 when the two Germanys were reunited as a single state. No changes were made in the symbols of the Federal Republic at the time of reunion.
