Concentration Camps
The first concentration camps came after Hitler's appointment as chancellor in Germany in 1933. German authorities, including the SA, the SS, the police, and local authorities, established camps around Germany. Some of these camps were in Oranienburg, Esterwegen, Dachau, and Lichtenburg. Once World War II began, there were six concentration camps: Dachau, Sachsenhausen, Buchenwald, Flossenburg, Mauthausen, and Ravensbruck. After 1937, the location of camps were based on the economy. For instance, Mauthausen was located near a large stone quarry which made work for prisoners more complex. Concentration camps didn't just hold Jewish prisoners hostage, but it became a site that the SS authorities could kill enemies of the Nazi Regime. It also held weapons and other goods for German war efforts.
