Concentration camp, internment centre for political prisoners and members of national or minority groups who are confined for reasons of state security, exploitation, or punishment, usually by executive decree or military order. Persons are placed in such camps often on the basis of identification with a particular ethnic or political group rather than as individuals and without benefit either of indictment or fair trial. Concentration camps are to be distinguished from prisons interning persons lawfully convicted of civil crimes and from prisoner-of-war camps in which captured military personnel are held under the laws of war. They are also to be distinguished from refugee camps or detention and relocation centres for the temporary accommodation of large numbers of displaced persons.
