The republican Reichsadler is based on the Reichsadler introduced by the Paulskirche Constitution of 1849, which was decided by the German National Assembly in Frankfurt upon Main, at the peak of the German civic movement demanding parliamentary participation and the unification of the German states. The achievements and signs of this movement had been mostly done away after its downfall and the political reaction in the 1850s. Only the tiny German Principality of Waldeck-Pyrmont upheld the tradition and continued to use the German colours called Schwarz-Rot-Gold in German ().
