List of wild concentration camps
This is a list of concentration camps established independently by Nazi-affiliated groups and organizations before the process was centralized by Heinrich Himmler in 1934. These camps were established in a variety of usually abandoned buildings, including workhouses, factories, cellars, and taverns to imprison mostly political prisoners. They are known as "wild" concentration camps due to their ad-hoc nature and lack of oversight. The 1933 Schutzhaft Protective Custody Order was the main pretense for interning German citizens in wild concentration camps.
