[1] Prussian government regions were not bodies of regional self-rule of the districts and cities comprised, but shear top-to-down government agencies to apply federal or state law and supervise local entities of self-rules, such as municipalities, rural and urban districts.
In 1815, after the Napoleonic Wars, West Prussia was divided into the Regions of Marienwerder and Danzig.
As a result of World War I, the Treaty of Versailles allocated most of West Prussia to the Second Polish Republic, and the Danzig Region was dissolved in 1920.
A few eastern areas of the Danzig Region remained in the Free State of Prussia in Weimar Germany, however.
The Danzig region had a German majority population with significant minorities of Poles and Kashubians.
