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 Switzerland
The white cross has been used as the field sign (attached to the clothing of combattants and to the cantonal war flags in the form of strips of linen) of the Old Swiss Confederacy since its formation in the late 13th or early 14th century. Its symbolism was described by the Swiss Federal Council in 1889 as representing "at the same the Christian cross symbol and the field sign of the Old Confederacy". As a national ensign, it was first used in 1800 during the Hundred Days by general Niklaus Franz von Bachmann, and as regimental flag of all cantonal troops from 1841. The federal coat of arms ("eidgenössisches Wappen") was defined in 1815 for the Restored Confederacy as the white-on-red Swiss cross in a heraldic shield. The current design was used together with a cross composed of five squares until 1889, when its dimensions were officially set.
