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.

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.
