Concentration camps, the epicenters of Nazi atrocities, represent a harrowing chapter of world and human history. Part of a highly organized system intended to decimate Europe's Jewish population and other groups deemed undesirable by Adolf Hitler's regime, these detention and extermination facilities enabled genocide to a degree never before seen in modern history. This volume chronicles the development of the concentration camp system and examines the various types of camps, the deplorable conditions and treatment the camps' victims faced, and the aftermath of the Holocaust. Documentation and eyewitness accounts from survivors and camp liberators supplement the narrative and highlight the horrors of the camps.
