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.
Modern architecture
In Germany, a modernist industrial movement, Deutscher Werkbund (German Work Federation) had been created in Munich in 1907 by Hermann Muthesius, a prominent architectural commentator. Its goal was to bring together designers and industrialists, to turn out well-designed, high quality products, and in the process to invent a new type of architecture. The organization originally included twelve architects and twelve business firms, but quickly expanded. The architects include Peter Behrens, Theodor Fischer (who served as its first president), Josef Hoffmann and Richard Riemerschmid. In 1909 Behrens designed one of the earliest and most influential industrial buildings in the modernist style, the AEG turbine factory, a functional monument of steel and concrete. In 1911–1913, Adolf Meyer and Walter Gropius, who had both worked for Behrens, built another revolutionary industrial plant, the Fagus factory in Alfeld an der Leine, a building without ornament where every construction element was on display. The Werkbund organized a major exposition of modernist design in Cologne just a few weeks before the outbreak of the First World War in August 1914. For the 1914 Cologne exhibition, Bruno Taut built a revolutionary glass pavilion.
