Flag of Germany
While the use of black-red-gold had been suggested in the Soviet zone in 1946, the Second People's Congress in 1948 decided to adopt the old black-white-red tricolour as a national flag for East Germany. This choice was based on the use of these colours by the National Committee for a Free Germany, a German anti-Nazi organisation that operated in the Soviet Union in the last two years of the war. In 1949, following a suggestion from Friedrich Ebert, Jr., the black-red-gold tricolour was instead selected as the flag of the German Democratic Republic upon the formation of this state on 7 October 1949. From 1949 to 1959, the flags of both West and East Germany were identical. On 1 October 1959, the East German government changed its flag with the addition of its coat of arms. In West Germany, these changes were seen as a deliberate attempt to divide the two Germanys. Displaying this flag in West Germany and West Berlin—where it became known as the (divider-flag)—was seen as a breach of the constitution and subsequently banned until the late 1960s.
Flag of Germany
The design of the Nazi flag was introduced by Hitler as the party flag in mid-1920, roughly a year before (29 July 1921) he became his political party's leader: a flag with a red background, a white disk and a black swastika "(Hakenkreuz)" in the middle. In "Mein Kampf", Hitler explained the process by which the Nazi flag design was created: It was necessary to use the same colours as Imperial Germany, because in Hitler's opinion they were "revered colours expressive of our homage to the glorious past and which once brought so much honour to the German nation." The most important requirement was that "the new flag ... should prove effective as a large poster" because "in hundreds of thousands of cases a really striking emblem may be the first cause of awakening interest in a movement." Nazi propaganda clarified the symbolism of the flag: the red colour stood for the social, white for the movement's national thinking and the swastika for the victory of the Aryan peoples over Jewry. Several designs by a number of different authors were considered, but the one adopted in the end was Hitler's personal design. Albert Speer stated in his memoirs that "in only two other designs did he (Adolf Hitler) execute the same care as he did his Obersalzberg house: that of the Reich War Flag and his own standard of Chief of State".
