Reichsgau Wartheland
During the German occupation of 1939–1945, Poznań was incorporated into the Third Reich as the capital of "Reichsgau Wartheland". Many Polish inhabitants were executed, arrested, expelled to the General Government or used as forced labour; at the same time, many Germans and Volksdeutsche were settled in the city. The German population increased from around 5,000 in 1939 (some 2% of the inhabitants) to around 95,000 in 1944.
