The term was formed from the words Reich (realm, empire) and Gau, the latter a deliberately medieval-sounding word with a meaning approximately equivalent to shire. The Reichsgaue were an attempt to resolve the administrative chaos resulting from the mutually overlapping jurisdictions and different boundaries of the NSDAP Party Gaue, placed under a Party Gauleiter, and the federal states, under a Reichsstatthalter responsible to the Ministry of the Interior (in the Prussian provinces, the equivalent post was that of Oberpräsident). Interior Minister Wilhelm Frick had long desired to streamline the German administration, and the Reichsgaue were the result: the borders of party Gaue and those of the federal states were to be identical, and the party Gauleiter also occupied the post of Reichsstatthalter.
