In 1941, around 280 million people in Europe, more than half the population, were governed by Germany or their allies and puppet states.[3] It comprised an area of 3,300,000 km2 (1,300,000 sq mi).[1]
Germany operated thousands of concentration camps in German-occupied Europe. The first camps were established in March 1933 immediately after Adolf Hitler became Chancellor of Germany. Following the 1934 purge of the SA, the concentration camps were run exclusively by the SS via the Concentration Camps Inspectorate and later the SS Main Economic and Administrative Office. Initially, most prisoners were members of the Communist Party of Germany, but as time went on different groups were arrested, including "habitual criminals", "asocials", and Jews.
After the beginning of World War II, people from German-occupied Europe were imprisoned in the concentration camps.
About 1.65 million people were registered prisoners in the camps, of whom about a million died during their imprisonment. Most of the fatalities occurred during the second half of World War II, including at least 4.7 million Soviet prisoners who were registered as of January 1945.
Following Allied military victories, the camps were gradually liberated in 1944 and 1945, although hundreds of thousands of prisoners died in the death marches.
After the expansion of Nazi Germany, people from countries occupied by the Wehrmacht were targeted and detained in concentration camps. In Western Europe, arrests focused on resistance fighters and saboteurs, but in Eastern Europe arrests included mass roundups aimed at the implementation of Nazi population policy and the forced recruitment of workers. This led to a predominance of Eastern Europeans, especially Poles, who made up the majority of the population of some camps. The ethnicities of captured people were various other groups from other different nationalities were transferred to Auschwitz or sent to local concentration camps.
Occupied countries
The countries occupied included all, or most, of the following nations or territories:
^Although there was substantial popular support in Austria for some type of (re)unification with Germany, Chancellors Engelbert Dollfuss and his successor Kurt Schuschnigg wanted to maintain at least some type of independence. Dollfuss had implemented an authoritarian regime now termed Austrofascism, continued by Schussnigg, which imprisoned many members of the Austrian Nazi Party and the Social Democratic Party which both favored unification. Violence by Austrian Nazi Party members including the assassination of Dollfuss, along with German propaganda and ultimately threats of invasion by Adolf Hitler, eventually led Schuschnigg to capitulate and resign. Hitler, however, did not wait for his hand-picked successor, Austrian Nazi Arthur Seyss-Inquart, to be sworn in and ordered German troops to invade Austria at dawn on 12 March 1938, where they were met with cheering crowds and an Austrian army previously ordered not to resist.
^In a referendum in 1935, over 90% of residents supported reunification with Germany over remaining a League of Nations protectorate of France and the United Kingdom or joining France.
