The Nazi occupants had merged the German-annexed territories of the Free City of Danzig (a free city under the League of Nations) and of the Polish Pomeranian Voivodeship (Polish: Województwo Pomorskie) and the German Marienwerder Region (German: Regierungsbezirk Marienwerder) in a Reichsgau, a kind of paramount Nazi administrative region.

Since the reorganisation of the league districts in 1933 football teams from places in the Free City of Danzig and the Marienwerder Region (called West Prussia Region between 1922 and 1939, not to be confused with the homonymous province dissolved in 1920) used to play in the Gauliga Ostpreußen-Danzig.

In 1940 the Gauliga Ostpreußen-Danzig skipped the addition Danzig from its name and comprised only teams from East Prussia in its then borders.

Until 1939 also clubs of Polish identity, such as Gedania Danzig, comprising many, but not only, Danzigers of Polish tongue, played in the Gauliga Ostpreußen-Danzig and qualified for the play-offs of the Ostpreußen-Danzig gauliga championships (German: Gaumeisterschaft).

The imminent collapse of Nazi Germany in 1945 gravely affected all Gauligas and football in Danzig-West Prussia ceased in 1944.
