Marienwerder (region)

West Prussia was divided into the regions of Danzig and Marienwerder in 1815, following the Napoleonic Wars.

Up until 1920, the Marienwerder Region comprised the urban districts (Stadtkreise) of Graudenz (Grudziądz) and Thorn (Toruń), both established on 1 January 1900.

The eastern part of Marienwerder that voted to be incorporated within the Weimar Republic was named the Region of West Prussia (Regierungsbezirk Westpreußen) while it was joined to the Province of East Prussia from 1922 to 1939, after which the original Marienwerder Region was restored until its dissolution in 1945.

Regierungsbezirk Marienwerder had a majority German population, with a large Polish minority.

[1] Each of the nineteen Regierungsbezirke featured a non-legislative governing body called a Regierungspräsidium or Bezirksregierung (regional government) headed by a Regierungspräsident (regional president), concerned mostly with applying state law to administrative decisions on municipalities within their jurisdiction and their umbrella organisations (the districts).
