The "Arms of the German Confederation" refers to the official heraldry used by the German Confederation (Deutscher Bund), a political union established in 1815 following the Congress of Vienna. It consisted of 39 member states, primarily former members of the Holy Roman Empire, ruled by various monarchies and confederates. The arms are symbolic of the unity and sovereignty of its member states within the larger context of the German Confederation. The design typically features a black shield with three golden vertical bars representing the Frankish empire, and above it, an Imperial double-headed eagle, which represents the Holy Roman Empire and the German King. This symbol served as the official emblem until 1866, marking the end of the Confederation.
