Nazi Germany maintained concentration camps (in German Konzentrationslager, or KZ) throughout the territories it controlled. The term was borrowed from the British concentration camps of the Second Anglo-Boer War. The concentration camps were administered since 1934 by Concentration Camps Inspectorate which in 1942 was merged into SS-Wirtschafts-Verwaltungshauptamt and were guarded by SS-Totenkopfverbände.
