The Reichsgau Danzig-West Prussia was a Nazi German province created on 8 October 1939 from annexed territory of the Free City of Danzig, the Greater Pomeranian Voivodship (Polish Corridor), and the Regierungsbezirk West Prussia of Gau East Prussia. Before 2 November 1939, the Reichsgau was called Reichsgau West Prussia. Though the name resembled the pre-1920 Prussian province of West Prussia, the territory was not identical. In contrast to the former Prussian province, the Reichsgau comprised the Bromberg (Bydgoszcz) region in the South and lacked the Deutsch-Krone (Walcz) region in the West.
