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.
Germany national football team
The national team's home kit has always been a white shirt, black shorts, and white socks. The colours are derived from the 19th-century flag of the North German State of Prussia. Since 1988, many of the home kit's designs incorporate details patterned after the modern German flag (with the noted exception of the 2002 World Cup kit, which was a reversion to the pure black-and-white scheme). For the 2014 World Cup, the German team used white shorts rather than the traditional black due to FIFA's kit clashing rule for the tournament. The away shirt colour has changed several times. Historically, green shirt with white shorts is the most often used alternative colour combination, derived from the DFB colours – though it is often erroneously reported that the choice is in recognition of the fact that Ireland, whose home shirts are green, were the first nation to play Germany in a friendly game after World War II. However, the first team to play Germany after WWII, as stated above, was actually Switzerland. Other colours such as red, grey and black have also been used.
