The Pomeranian Voivodeship or Pomorskie Voivodeship (Polish: Województwo Pomorskie) was an administrative unit of interwar Poland (from 1919 to 1939). It ceased to function in September 1939, following the German and Soviet invasion of Poland.

Most of the territory of Pomeranian province became part of the current Kuyavian-Pomeranian Voivodeship, of which one of two capitals is the same as the interwar voivodeship's Toruń; the second one is Bydgoszcz.

The name Pomerania derives from the Slavic po more, meaning "by the sea" or "on the sea".

History

This was a unit of administration and local government in the Republic of Poland (II Rzeczpospolita) established in 1919 after World War I from the majority of the Prussian province of West Prussia (made out of territories taken in Partitions of Poland which was returned to Poland. Toruń was the capital. In 1938–1939, the voivodeship extended to the south at the expense of Poznań Voivodeship and Warsaw Voivodeship, and was called Great Pomerania afterwards (see: Territorial changes of Polish Voivodeships on April 1, 1938).

During World War II, it was occupied by Nazi Germany and unilaterally annexed as Reichsgau Danzig-Westpreußen ("Reich province of Danzig-West Prussia"). Poles and Jews were classified as untermenschen by German authorities and their intended fate slavery and extermination. In 1945, the region was returned to Poland. In 1945 out of its northern territory, the new voivodeship of Gdańsk was formed, including annexed territories of the Free City of Danzig and of German Prussian Province of Pomerania and German Prussian Province of East Prussia. The bulk of the old voivodeship was enlarged by annexed territories of the German Prussian Province of Pomerania and later renamed into Bydgoszcz voivodeship. In the years 1975–1998, it was reorganized into the voivodeships of Gdańsk, Elbląg, Bydgoszcz, Toruń, and Włocławek.
