The states of the German Confederation were member states of the German Confederation, from 20 June 1815 until 24 August 1866.
The state of Prussia developed from the State of the Teutonic Order. The original flag of the Teutonic Knights had been a black cross on a white flag. Emperor Frederick II in 1229 granted them the right to use the black Eagle of the Holy Roman Empire. This "Prussian Eagle" remained the coats of arms of the successive Prussian states until 1947.
This is a list of coats of arms of Germany.
