Marienwerder (region)

Regierungsbezirk Marienwerder was a Regierungsbezirk (governorate), or administrative region, of Prussia from 1815 until 1945. Marienwerder region was part of the Province of West Prussia from 1815–1829, and again 1878–1920, belonging to the Province of Prussia in the intermittent years. Marienwerder region was then placed under an inter-allied commission from 1920–22. It was known as Regierungsbezirk Westpreußen ("West Prussia") while it was joined to the Province of East Prussia from 1922–39, after which its original name was restored until its dissolution in 1945. The regional capital was Marienwerder (Kwidzyn).

Most of Polish Royal Prussia was annexed by King Frederick the Great of Prussia in the 1772 First Partition of Poland. The town of Marienwerder, previously in Ducal Prussia, became an administrative capital of the newly acquired territory, which became the Province of West Prussia on 31 January 1773.

West Prussia was divided into Regierungsbezirk Marienwerder and Regierungsbezirk Danzig in 1815 after the Napoleonic Wars. While the governor and provincial authorities were based in Danzig (Gdańsk), the provincial court was in the town of Marienwerder.

From 1815-18, West Prussia was reorganized into Kreise, or districts, within each government region. The Marienwerder region included the rural districts (Landkreise) of Deutsch-Krone, Flatow, Graudenz, Konitz, Kulm, Löbau, Marienwerder, Rosenberg, Schlochau, Schwetz, Strasburg, Stuhm, and Thorn.
