Prisoners

Before World War II, most prisoners in the concentration camps were Germans. 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. By the end of the war, only 5 to 10 per cent of the camp population was "Reich Germans" from Germany or Austria. More than 100,000 Soviet prisoners of war and smaller groups from other nationalities were transferred to the concentration camps in direct violation of the Geneva Convention.

Most Jews who were persecuted and killed during the Holocaust were never prisoners in concentration camps. Significant numbers of Jews were imprisoned beginning in November 1938 because of Kristallnacht, after which they were always overrepresented as prisoners. During the height of the Holocaust from 1941 to 1943, the Jewish population of the concentration camps was low. Extermination camps for the mass murder of Jews— Kulmhof, Belzec, Sobibor, and Treblinka —were set up outside the concentration camp system. The existing IKL camps Auschwitz and Majdanek gained additional function as extermination camps. After mid-1943, some forced-labor camps for Jews and some Nazi ghettos were converted into concentration camps. Other Jews entered the concentration camp system after being deported to Auschwitz. Despite many deaths, as many as 200,000 Jews survived the war inside the camp system.
