Military occupations of World War II

Military occupations during World War II involved extensive control of conquered Poland, France, Soviet Union, Norway, Denmark, Belgium, Netherlands, Greece, Yugoslavia, China, Korea, Philippines, Indonesia (Dutch East Indies), Malaya, and numerous Pacific islands by Axis and Allied powers. Occupations combined military governance, civilian administrations, collaborationist regimes, and occupation policies that affected combat operations and postwar settlements such as the Potsdam Conference and Yalta Conference.

Background and Causes

Occupation practices evolved from prewar doctrines espoused by states including Nazi Germany, Imperial Japan, Fascist Italy, Soviet Union, United Kingdom, United States, and Free France. Strategic campaigns such as the Invasion of Poland, Fall of France, Operation Barbarossa, Battle of Britain, Battle of Crete, Pacific War, and Malayan Campaign created occupied zones. Ideologies including Nazism, Japanese imperialism, Italian Fascism, and Communism shaped occupation aims, while treaties like the Molotov–Ribbentrop Pact and armistices such as the Armistice of Cassibile redefined spheres of influence. Precedents from the First World War and interwar doctrines influenced legal interpretations later debated at the Nuremberg Trials and International Military Tribunal for the Far East.

Axis and Allied Occupation Policies

Axis powers implemented disparate systems: Nazi Germany pursued racialized policies in Poland General Government, Reichskommissariat Ukraine, Reichskommissariat Ostland, and annexations like Alsace-Lorraine analogues, often overseen by officials such as Wilhelm Frick, Alfred Rosenberg, and Hermann Göring’s economic commissars. Imperial Japan instituted puppet administrations in Manchukuo, Wang Jingwei regime, and military governments in Philippines, using commanders like Tojo Hideki and Shōwa Emperor (Hirohito). Fascist Italy created protectorates in Albania and parts of the Balkans. Allied occupations by United Kingdom, United States of America, Soviet Union, and Free French Forces combined military governments in liberated areas and occupation zones in defeated Germany and Japan, administered via institutions including the Allied Control Council and SCAP (Douglas MacArthur).

Major Occupied Territories and Administrative Structures

Examples include German civil administrations in the Protectorate of Bohemia and Moravia, military governors in Vichy France and coastal zones, and SS-led systems in Zamosc-era ethnic policies. Japanese structures ranged from Southern Expeditionary Army Group control in Dutch East Indies to military police units like the Kempeitai in Taiwan and Korea. Soviet occupation authorities established People's Commissariat offices and trained local communists in territories seized during Operation Bagration and the Vistula–Oder Offensive. Allied military governments framed occupation law in the U.S. Military Government in Germany (OMGUS), British Military Administration, and the Allied occupation of Japan. Colonial administrations by Vichy and Netherlands interacted with occupation mandates in Indochina, Ceylon, and Siam.

Resistance, Collaboration, and Civilian Impact

Occupied populations saw resistance movements such as the French Resistance, Polish Home Army, Yugoslav Partisans, Greek People's Liberation Army (ELAS), Soviet partisans, Eighth Route Army, and Moro resistance in the Philippines. Collaborationist entities included the Vichy regime, Vidkun Quisling’s government, the Romanian administration under Ion Antonescu, Vichy French Milice, and Wang Jingwei. Occupation produced mass civilian suffering exemplified by the Holocaust, Bataan Death March, Nanjing Massacre, Babi Yar, Khatyn massacre, and Korean comfort women system administered by the Imperial Japanese Army. Reprisals such as the Oradour-sur-Glane massacre and collective punishments in Belarus fueled cycles of violence.

Economic Exploitation and Resource Extraction

Occupying powers organized systematic extraction: Reichswerke Hermann Göring requisitions in Silesia, coal and steel seizures in the Ruhr under Albert Speer policies, grain and labor requisitions in Ukraine and Belarus for the Wehrmacht, rubber and oil expropriation in Dutch East Indies and Malaya by Imperial Japanese Navy, and forced labor programs using POWs from Soviet Union, United Kingdom, and United States. Corporations such as IG Farben, Krupp, Mitsubishi, and Yokohama Specie Bank profited while institutions like the Office of Strategic Services and Allied Shipping Control sought to interdict resources. Economic measures provoked famine in Leningrad and food shortages in Holland (Hunger Winter).

Legal Status, War Crimes, and Postwar Accountability

Occupation regimes raised legal questions adjudicated at the Nuremberg Trials, Tokyo Trials, and subsequent proceedings before national courts in Poland, France, Norway, and Yugoslavia. Charges addressed crimes against humanity, violations of the Hague Conventions (1907), deportations, massacres like Jasenovac, and sexual slavery cases examined later in suits against Japanese government. Command responsibility doctrines implicated leaders including Adolf Hitler, Hirohito (disputed role), Heinrich Himmler, Hideki Tojo, Ion Antonescu, and Benito Mussolini, while denazification and purges affected administrators like Klaus Barbie prosecuted in later decades.

Liberation, Transition, and Long-term Consequences

Liberation campaigns by Red Army, U.S. Army, British Army, Free French Forces, and Chinese National Revolutionary Army restored sovereignty in many areas but left new realities: Soviet occupations created People's Republics in eastern Europe and influenced the Iron Curtain and Cold War tensions articulated at Truman Doctrine and Marshall Plan negotiations. Territorial changes ratified at Paris Peace Treaties and Potsdam Conference redrew borders affecting Silesia, East Prussia, and Korean peninsula. Long-term consequences included population displacements like the Expulsion of Germans after World War II, lingering war crime memory in Israel and Poland, economic reconstruction via European Recovery Program, and legal legacies shaping Geneva Conventions (1949) and international humanitarian law institutions such as the International Criminal Court.
