Nazi Germany maintained concentration camps (German: Konzentrationslager [kɔntsɛntʁaˈtsi̯oːnsˌlaːɡɐ], KZ or KL) throughout the territories it controlled. The first Nazi concentration camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control over the police through Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring.
