Deutsche Bundespost 150th anniversary of the Hambacher Festival.

DEUTSCHE BUNDESPOST on 27 May 1982 issued a First Day Cover stamps to commemorate the 150th anniversary of the Hambacher Festival.

The Hambacher Festival was a German national democratic festival celebrated from 27 May to 30 May 1832 at Hambach Castle, near Neustadt an der Weinstraße, in present-day Rhineland-Palatinate, Germany. The event was disguised as a nonpolitical county fair.[clarification needed] It was one of the main public demonstrations in support of German unity, freedom and democracy during the Vormärz era.

The Festival confirmed the establishment of the combination of black, red and gold as a symbol of a democratic movement for a united Germany. The colours were later used by democratic revolutionaries in the Revolutions of 1848 as a symbol of German unity, but it was not achieved until 1871 and, even then, to Otto von Bismarck's specifications. After World War I, Black-Red-Gold were adopted by the Weimar Republic as the national colours of Germany and are used on the modern German flag.
