Depicts the coat of arms of the German Reich (1919–28), Imperial Eagle (Reichsadler) facing left, surrounded by the inscription "Constitution Day 11th of August" and date.

After the introduction of the republic the coat of arms of Germany was also altered accounting for the political changes. The Weimar Republic (1918–1933), retained the Reichsadler without the symbols of the former Monarchy (Crown, Collar, Breast shield with the Prussian Arms). This left the black eagle with one head, facing to the right, with open wings but closed feathers, with a red beak, tongue and claws and white highlighting.

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 Republic's first President, Friedrich Ebert, signed the new German constitution into law on 11 August 1919. In 1921 the Constitution Day on 11 August was declared the national holiday, to be celebrated as ‘the day democracy in Germany was born’. The first celebrations in 1921 were rather academic in character and modest in scale. In the years that followed, however, they became more elaborate – featuring official gatherings and open days at the Reichstag, military parades, processions, sporting events, and fairs. However, these events did little to increase the holiday’s popularity.
