German occupation of Eastern Europe was a multifaceted series of invasions, occupations, and administrations carried out by Nazi Germany and its allies across Poland, the Baltic States, Belarus, Ukraine, Moldova, and parts of the Balkans between 1939 and 1945. It combined military campaigns, ideological policies from the Nazi Party, and administrative frameworks derived from directives issued by figures such as Adolf Hitler, Hermann Göring, Heinrich Himmler, and Alfred Rosenberg. The occupation reshaped frontiers confirmed at the Potsdam Conference and influenced postwar institutions including the United Nations and the Nuremberg Trials.
The occupation built on diplomatic and military precursors such as the Molotov–Ribbentrop Pact, the Invasion of Poland (1939), and the staged crises surrounding the Annexation of Austria and the Munich Agreement. Strategic planning drew on concepts from the Generalplan Ost and ideological works promoted by Alfred Rosenberg and Rudolf Hess, while military preparations involved commands including the OKW, OKH, and army groups led by generals like Fedor von Bock and Gerd von Rundstedt. Prewar occupations and puppet regimes—Protectorate of Bohemia and Moravia, Slovak Republic (1939–1945), and collaborations in the Kingdom of Hungary—provided templates later applied in the east.
Major campaigns included Operation Barbarossa, the Battle of Smolensk (1941), the Siege of Leningrad, the Battle of Kiev (1941), and the Battle of Stalingrad, each involving formations such as Heer, Waffen-SS, and Einsatzgruppen under commanders like Heinrich Himmler and Reinhard Heydrich. Occupation policies combined security measures inspired by Kommissarbefehl and anti-partisan operations such as Operation Harvest Festival with population control strategies articulated in Generalplan Ost. Axis partners—Romania, Finland, Croatia (Independent State of), and Italy—implemented complementary operations including the Siege of Odessa and campaigns in the Balkans Campaign.
Administrative systems ranged from civil administrations like the General Government established in Kraków and governed initially by Hans Frank, to military administrations in occupied Soviet territories and Reichskommissariats such as Reichskommissariat Ostland and Reichskommissariat Ukraine supervised by officials like Hinrich Lohse and Erich Koch. Law enforcement relied on institutions including the Geheime Staatspolizei, Ordnungspolizei, and local auxiliaries drawn from nationalist movements such as Organization of Ukrainian Nationalists and the Forest Brothers. Occupation governance intersected with diplomatic arrangements including the Tripartite Pact and negotiations involving the Vichy France–era contacts and the German–Soviet Frontier Treaty adjustments.
Economic policies pursued requisitioning, forced labor, and exploitation of raw materials to feed the Third Reich and the wartime industry centered in the Reichswerke Hermann Göring and firms such as IG Farben and Siemens. Systems included forced labor drafted under the Arbeitsdienst and deportations coordinated through agencies like the Reich Ministry of Armaments and War Production and Alfred Rosenberg's offices. Agricultural expropriation, grain levies, and extraction of oil from fields in Ploiești under Romania involvement, as well as timber and minerals from Ukraine and the Baltic States, were overseen by economic planners citing directives from Hermann Göring and administrators in Berlin.
Civilians experienced mass deportations, famine, and demographic engineering implemented via directives from the SS and occupation ministries; notable affected urban centers included Warsaw, Kiev, Vilnius, and Riga. Resistance movements formed across occupied territories: the Polish resistance movement in World War II including Armia Krajowa, Soviet-aligned partisans under commanders such as Sidor Kovpak, the Yugoslav Partisans led by Josip Broz Tito, Lithuanian and Latvian Forest Brothers, and Ukrainian insurgent factions including Ukrainian Insurgent Army. Reprisals featured massacres like the Wola massacre, anti-partisan operations like Operation Spring Breeze (1943) and large-scale civilian pacification exemplified in the Khatyn massacre.
The occupation facilitated the Holocaust across Eastern Europe through mass shootings by Einsatzgruppen at sites such as Babi Yar and through extermination via camps including Treblinka, Auschwitz-Birkenau, Sobibór, Belzec, and Majdanek. Persecutions targeted Jews, Roma, Polish intelligentsia during operations like AB-Aktion, prisoners of war per Kommissarbefehl, and minorities targeted in ethnic cleansing campaigns aligned with Generalplan Ost. Collaborationist police forces and local auxiliaries participated in deportations to ghettos such as Łódź Ghetto and Warsaw Ghetto, leading to events like the Warsaw Ghetto Uprising.
The German retreat followed defeats at Battle of Kursk, Operation Bagration, and the Vistula–Oder Offensive, culminating in Soviet advances to Berlin and negotiations at the Potsdam Conference that redrew borders and sanctioned population transfers under agreements like the Polish–Soviet border changes (1945). Liberation involved armies including the Red Army, Allied operations by British Expeditionary Force elements in the north and western campaigns influencing outcomes in Hungary and Romania. Postwar consequences included the Nuremberg Trials, widespread displacement formalized in population transfers, the imposition of Soviet Union–aligned regimes in Eastern Europe, and long-term legal and moral reckonings in institutions such as the International Military Tribunal and subsequent war crimes prosecutions.
