Of the territories annexed from Poland and the Free City of Danzig in 1939, Reichsgau Wartheland and Reichsgau Danzig-West Prussia were created. Annexed territories of pre-war Poland not within these two Reichsgaue were incorporated into the neighboring Gaue East Prussia and Silesia. The Grand Duchy of Luxembourg as well as Alsace-Lorraine, annexed from pre-war France in 1940, were attached to the bordering Southwestern Gaue of Nazi Germany.
