Nazi Camps
Between 1933 and 1945, Nazi Germany and its allies established more than 44,000 camps and other incarceration sites (including ghettos). The perpetrators used these sites for a range of purposes, including forced labor, detention of people thought to be enemies of the state, and for mass murder.
In March 1933, the first concentration camp, Dachau, opened outside of Munich, Germany. It was used primarily for political prisoners and was the longest running camp in operation, until its liberation in April 1945.
Nazi officials established more than 44,000 incarceration sites during the time of the Third Reich. This estimate is based on continuing research of contemporary sources, including the perpetrators’ own records.
Not all facilities established were concentration camps, though they are often referred to in this way. These sites varied in purpose and in the types of prisoners detained there.
Early Camps (1933–38)
From its rise to power in 1933, the Nazi regime built a series of incarceration sites to imprison and eliminate real and perceived "enemies of the state." Most prisoners in the early concentration camps were political prisoners—German Communists, Socialists, Social Democrats—as well as Roma (Gypsies), Jehovah's Witnesses, gay men and men accused of homosexuality, and persons accused of "asocial" or socially deviant behavior. Many of these sites were called concentration camps. The term concentration camp refers to a camp in which people are detained or confined, usually under harsh conditions and without regard to legal norms of arrest and imprisonment that are acceptable in a constitutional democracy.
After Germany's annexation [Anschluss] of Austria in March 1938, Austrian political prisoners came into the Nazi concentration camp system. Following the violent Kristallnacht ("Night of Broken Glass") pogroms in November 1938, Nazi officials conducted mass arrests of adult male Jews throughout the country, the first time Jews were arrested en masse precisely because they were Jews. Over 30,000 German Jews were incarcerated in the Dachau, Buchenwald, and Sachsenhausen concentration camps in Germany, initially until each could provide proof of their ability to emigrate.
Types of Camps
Many people refer to all of the Nazi incarceration sites during the Holocaust as concentration camps. The term concentration camp is used very loosely to describe places of incarceration and murder under the Nazi regime, however, not all sites established by the Nazis were concentration camps. Nazi-established sites include:
Concentration camps: For the detention of civilians seen as real or perceived “enemies of the Reich.”
Forced-labor camps: In forced-labor camps, the Nazi regime brutally exploited the labor of prisoners for economic gain and to meet labor shortages. Prisoners lacked proper equipment, clothing, nourishment, or rest.
Transit camps: Transit camps functioned as temporary holding facilities for Jews awaiting deportation. These camps were usually the last stop before deportations to a killing center.
Prisoner-of-war camps: For Allied prisoners of war, including Poles and Soviet soldiers.
Killing centers: Established primarily or exclusively for the assembly-line style murder of large numbers of people immediately upon arrival to the site. There were 5 killing centers for the murder primarily of Jews. The term is also used to describe “euthanasia” sites for the murder of disabled patients.
Other types of incarceration sites numbered in the tens of thousands. These included but were not limited to early camps; “euthanasia” facilities for the murder of disabled patients; Gestapo, SS and German justice detention centers; so-called “Gypsy” camps, and Germanization facilities.
Concentration Camps
Concentration camps are often inaccurately compared to a prison in modern society. But concentration camps, unlike prisons, were independent of any judicial review. Nazi concentration camps served three main purposes:
To incarcerate real and perceived “enemies of the state." These persons were incarcerated for indefinite amounts of time.
To eliminate individuals and small, targeted groups of individuals by murder, away from the public and judicial review.
To exploit forced labor of the prisoner population. This purpose grew out of a labor shortage.
