Polish areas annexed by Nazi Germany directly following the Invasion of Poland (1939) comprised nearly 92,000 square kilometers of pre-war Polish territory, which were incorporated into the Greater Germanic Reich. These annexations, executed through decrees by Adolf Hitler in October 1939, were a central component of Nazi racial and expansionist ideology, aiming to permanently eliminate the Polish state and exploit its resources. The brutal occupation regime in these areas featured intense Germanization, mass expulsions, economic plunder, and the systematic murder of the Polish intelligentsia and Jewish population.

Background and historical context

The annexation plans were rooted in long-standing irredentist and expansionist goals within segments of the German political establishment, particularly following Poland's return to independence after World War I. The Nazi Party, under Adolf Hitler, explicitly outlined the destruction of Poland in Mein Kampf and through directives like the Hossbach Memorandum. The Molotov–Ribbentrop Pact, signed in August 1939 between Nazi Germany and the Soviet Union, contained a secret protocol dividing Eastern Europe into spheres of influence, paving the way for the joint Invasion of Poland (1939). Immediate plans for annexation were formalized during the September Campaign by officials like Heinrich Himmler and Adolf Hitler.

Administrative divisions and territorial changes

The annexed territories were organized into new or expanded administrative units of the Third Reich, known as Reichsgaus. The bulk of the land was incorporated into Reichsgau Wartheland (centered on Posen) and Reichsgau Danzig-West Prussia (centered on Danzig). Parts of East Upper Silesia were attached to the Province of Silesia, while regions surrounding Ciechanów (Zichenau) and Suwałki (Sudauen) were incorporated into East Prussia. Key cities like Łódź (renamed Litzmannstadt) and Bydgoszcz (Bromberg) became major administrative centers under direct German rule.

Germanization policies and population transfers

The Nazi regime implemented a ruthless policy of Germanization, seeking to ethnically reconfigure the region. This involved the creation of the German People's List (Deutsche Volksliste) to classify inhabitants, with ethnic Germans granted privileges. The Polish population faced mass expulsion; hundreds of thousands were forcibly deported to the General Government in operations overseen by the SS and Reich Security Main Office. Simultaneously, ethnic Germans from the Baltic states and other parts of Eastern Europe were resettled into the annexed territories under programs like the Heim ins Reich initiative managed by the SS Race and Settlement Main Office.

Economic exploitation and forced labor

The annexed areas were subjected to systematic economic plunder to fuel the German war effort. Industrial complexes, particularly in Upper Silesia, were seized by German conglomerates like the Reichswerke Hermann Göring. Agricultural output was confiscated for the Wehrmacht and German civilians. The Polish population was subjected to widespread forced labor, with many conscripted as Eastern Workers and sent to factories and farms across Germany. The Łódź Ghetto and others were also used as sources of slave labor before the inhabitants were murdered in extermination camps like Chełmno and Auschwitz-Birkenau.

Resistance and repression

Resistance in the annexed territories was met with extreme brutality. The Intelligenzaktion and other operations aimed to decapitate Polish society by murdering teachers, priests, and officials in mass executions at sites like Piaśnica and in the Bydgoszcz area. The Gestapo and Einsatzgruppen were particularly active. Despite this, a strong underground resistance developed, including units of the Home Army and organizations like Union of Armed Struggle, which engaged in sabotage, intelligence gathering, and clandestine education. Reprisals for resistance activities were swift and severe, often involving public executions and the destruction of entire villages.

Aftermath and legacy

Following the Red Army's advance and the defeat of Nazi Germany in 1945, the annexed territories were returned to Poland under the terms of the Potsdam Agreement. The post-war Polish government subsequently expelled most of the remaining German population. The legacy of the annexation is a central element of Polish historical memory of World War II, symbolizing the brutality of the Nazi occupation of Poland. The events are documented in trials such as the Nuremberg trials and are memorialized at numerous sites, including the Museum of the Second World War in Gdańsk and the Institute of National Remembrance in Warsaw.
