Posen-West Prussia
In 1938, German Posen-West Prussia was dissolved and its former West Prussian territory was attached to the German Pomeranian Gau. Also in 1938, the Polish Pomeranian Voivodship was expanded southward to comprise the Bydgoszcz region. The resulting enlarged Pomeranian voivodship was called Greater Pomeranian Voivodship ("Wielkopomorskie").
