Regierungsbezirk
The first Regierungsbezirke were created by the Kingdom of Prussia in 1808/16, which divided its provinces into 25 Regierungsbezirke. The Regierungsbezirke of North Rhine-Westphalia are in direct continuation of those created in 1815. Other states of the German Empire created similar entities, named Kreishauptmannschaft (in Saxony) or Kreis (in Bavaria and Württemberg) (not to be confused with the Kreis or Landkreis today). During the Third Reich, the Nazi government unified the naming; since then all these entities are called Regierungsbezirk.
