Auschwitz was the biggest of the Nazi concentration and extermination camps. Located in southern Poland, it was founded as a holding facility for political prisoners. However, it developed into a network of concentration camps where Jews and other perceived enemies of the Nazi regime were murdered, often in gas chambers or forced to work as slaves.
