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.

The 1815–16 Congress of Vienna led to the creation of the German Confederation, a loose union of all remaining German states after the Napoleonic Wars. The Confederation was created as a replacement for the now-extinct Holy Roman Empire, with Francis I of Austria—the last Holy Roman Emperor—as its president. The confederation did not have a flag of its own, although the black-red-gold tricolour is sometimes mistakenly attributed to it.
Upon returning from the war, veterans of the Lützow Free Corps founded the fraternity in Jena in June 1815. The Jena eventually adopted a flag with three equal horizontal bands of red, black, and red, with gold trim and a golden oak branch across the black band, following the colours of the uniforms of the Free Corps. Since the students who served in the Lützow Free Corps came from various German states, the idea of a unified German state began to gain momentum within the and similar that were subsequently formed throughout the Confederation. On 18 October 1817, the fourth anniversary of the Battle of Leipzig, hundreds of fraternity members and academics from across the Confederation states met in Wartburg in Saxe-Weimar-Eisenach (in modern Thuringia), calling for a free and unified German nation.
