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.
French ensigns
Until the French Revolution most merchants flew designs composed of blue and white. In 1790, however, the revolution joined all three colours in one flag, and the new ensign became the white flag with a canton of three equal columns of red, white, and blue. Since the white field was too royal for the taste of the revolution, on 27 pluviôse year II of the French Republican Calendar (15 February 1794), the flag and the ensign were changed to the design of the current flag of France: Three columns of equal width, of blue, white, and red. The same banner was again decreed to be the flag on 7 March 1848.
