The last part of this exhibition starts with the Revolution of 1918. Visitors learn about the time of the Weimar Republic, the architecture of the Bauhaus era, the historical German youth movement and find out whether Germany and France really were arch-enemies.
Other parts of this collection are Baden in the Third Reich, the Hitler Youth, the persecution of political dissidents and ethnic minorities and finally World War II. After this, the visitors see how Baden was rebuilt from the ruins, and they learn about the problem of establishing the state of Baden-Württemberg. A special area in the room is dedicated solely to the Badner Lied, the inofficial anthem, with its numerous verses.
