The Schutzstaffel was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.
Nacht und Nebel, meaning Night and Fog, also known as the Night and Fog Decree, was a directive issued by Adolf Hitler on 7 December 1941 targeting political activists and resistance "helpers" in the territories occupied by Nazi Germany during World War II, who were to be imprisoned, murdered, or made to disappear, while the family and the population remained uncertain as to the fate or whereabouts of the alleged offender against the Nazi occupation power. Victims who disappeared in these clandestine actions were often never heard from again.
Organisation Todt was a civil and military engineering organisation in Nazi Germany from 1933 to 1945, named for its founder, Fritz Todt, an engineer and senior member of the Nazi Party. The organisation was responsible for a huge range of engineering projects both in Nazi Germany and in occupied territories from France to the Soviet Union during the Second World War. The organisation became notorious for using forced labour. From 1943 until 1945 during the late phase of the Third Reich, OT administered all constructions of concentration camps to supply forced labour to industry.
The European theatre of World War II was one of the two main theatres of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin, and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May. On 5 June 1945, the Berlin Declaration proclaiming the unconditional surrender of Germany to the four victorious powers was signed. The Allied powers fought the Axis powers on two major fronts, but there were other fronts varying in scale from the Italian campaign, to the Polish Campaign, as well as in a strategic bombing offensive and in the adjoining Mediterranean and Middle East theatre.
The military occupation of Czechoslovakia by Nazi Germany began with the German annexation of the Sudetenland in 1938, continued with the creation of the Protectorate of Bohemia and Moravia, and by the end of 1944 extended to all parts of Czechoslovakia.
From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps, including subcamps on its own territory and in parts of German-occupied Europe.
The Eastern Front was a theatre of World War II fought between the European Axis powers and Allies, including the Soviet Union (USSR) and Poland. It encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans), and lasted from 22 June 1941 to 9 May 1945. Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front, including 9 million children. The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations. It is noted by historian Geoffrey Roberts that "More than 80 percent of all combat during the Second World War took place on the Eastern Front".
Hiwi, the German abbreviation of the word Hilfswilliger or, in English, auxiliary volunteer, designated, during World War II, a member of different kinds of voluntary auxiliary forces made up of recruits indigenous to the territories of Eastern Europe occupied by Nazi Germany. Adolf Hitler reluctantly agreed to allow recruitment of Soviet citizens in the Rear Areas during Operation Barbarossa. In a short period of time, many of them were moved to combat units.
Non-Germans in the German armed forces during World War II were volunteers, conscripts and those otherwise induced to join who served in Nazi Germany's armed forces during World War II. In German war-time propaganda those who volunteered for service were referred to as Freiwillige ("volunteers"). At the same time, many non-Germans in the German armed forces were conscripts or recruited from prisoner-of-war camps.
During World War II, the German Wehrmacht committed systematic war crimes, including massacres, mass rape, looting, the exploitation of forced labour, the murder of three million Soviet prisoners of war, and participated in the extermination of Jews. While the Nazi Party's own SS forces was the organization most responsible for the genocidal killing of the Holocaust, the regular armed forces of the Wehrmacht committed many war crimes of their own, particularly on the Eastern Front.
Crimes against the Polish nation committed by Nazi Germany and Axis collaborationist forces during the invasion of Poland, along with auxiliary battalions during the subsequent occupation of Poland in World War II, included the genocide of millions of Polish people, especially the systematic extermination of Jewish Poles. These mass killings were enacted by the Nazis with further plans that were justified by their racial theories, which regarded Poles and other Slavs, and especially Jews, as racially inferior Untermenschen.
Holocaust victims were people targeted by the government of Nazi Germany based on their ethnicity, religion, political beliefs, disability or sexual orientation. The institutionalized practice by the Nazis of singling out and persecuting people resulted in the Holocaust, which began with legalized social discrimination against specific groups, involuntary hospitalization, euthanasia, and forced sterilization of persons considered physically or mentally unfit for society. The vast majority of the Nazi regime's victims were Jews, Sinti-Roma peoples, and Slavs but victims also encompassed people identified as social outsiders in the Nazi worldview, such as homosexuals, and political enemies. Nazi persecution escalated during World War II and included: non-judicial incarceration, confiscation of property, forced labor, sexual slavery, death through overwork, human experimentation, undernourishment, and execution through a variety of methods. For specified groups like the Jews, genocide was the Nazis' primary goal.
Austria was part of Nazi Germany from 13 March 1938 until 27 April 1945, when Allied-occupied Austria declared independence from Nazi Germany.
During World War II, Soviet prisoners of war (POWs) held by Nazi Germany and primarily in the custody of the German Army were starved and subjected to deadly conditions. Of nearly six million that were captured, around three million died during their imprisonment.
The use of slave and forced labour in Nazi Germany and throughout German-occupied Europe during World War II took place on an unprecedented scale. It was a vital part of the German economic exploitation of conquered territories. It also contributed to the mass extermination of populations in occupied Europe. The Germans abducted approximately 12 million people from almost twenty European countries; about two thirds came from Central Europe and Eastern Europe. Many workers died as a result of their living conditions – extreme mistreatment, severe malnutrition and abuse were the main causes of death. Many more became civilian casualties from enemy (Allied) bombing and shelling of their workplaces throughout the war. At the peak of the program the forced labourers constituted 20% of the German work force. Counting deaths and turnover, about 15 million men and women were forced labourers at one point during the war.
The Wehrmacht were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
After the Munich Agreement, the Soviet Union pursued a rapprochement with Nazi Germany. On 23 August 1939 the Soviet Union signed a non-aggression pact with Germany which included a secret protocol that divided Eastern Europe into German and Soviet "spheres of influence", anticipating potential "territorial and political rearrangements" of these countries. Germany invaded Poland on 1 September 1939, starting World War II. The Soviets invaded eastern Poland on 17 September. Following the Winter War with Finland, the Soviets were ceded territories by Finland. This was followed by annexations of the Baltic states and parts of Romania.
The diplomatic history of World War II includes the major foreign policies and interactions inside the opposing coalitions, the Allies of World War II and the Axis powers, between 1939 and 1945.
The German occupation of Belgium during World War II began on 28 May 1940, when the Belgian army surrendered to German forces, and lasted until Belgium's liberation by the Western Allies between September 1944 and February 1945. It was the second time in less than thirty years that Germany had occupied Belgium.
The occupation of Poland by Nazi Germany and the Soviet Union during World War II (1939–1945) began with the Invasion of Poland in September 1939, and it was formally concluded with the defeat of Germany by the Allies in May 1945. Throughout the entire course of the occupation, the territory of Poland was divided between Nazi Germany and the Soviet Union (USSR), both of which intended to eradicate Poland's culture and subjugate its people. In the summer-autumn of 1941, the lands which were annexed by the Soviets were overrun by Germany in the course of the initially successful German attack on the USSR. After a few years of fighting, the Red Army drove the German forces out of the USSR and crossed into Poland from the rest of Central and Eastern Europe.
