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 Europe
In 1997, the "Central and Eastern Eurobarometer" poll included a section intending to "discover the level of public awareness of the European Union" in what were then candidate countries in Central and Eastern Europe. Interviewees were shown "a sticker of the European flag" and asked to identify it. Responses considered correct were: the European Union, the European Community, the Common Market, and "Europe in general". 52% of those interviewed gave one of the correct answers, 15% gave a wrong answer (naming another institution, such as NATO or the United Nations), and 35% could or would not identify it.
In 2002, Dutch architect Rem Koolhaas designed a new flag, dubbed the "barcode", as it displayed the colours of the national flags of the EU member states in vertical stripes. It was never officially adopted by the EU or any organisation, but it was used as the logo of the Austrian EU Presidency in 2006.
