Concentration Camp Badges Explained

Here is a reproduction of an original chart explaining the system behind the badges that Concentration Camp prisoners wore. The background is the barb-wire fence from one of the camps. There are columns for criminals, immigrants, Jehovah's Witnesses (Bibelforscher -- literally Bible Discoverer, which is an interesting appellation), Homosexual, and Asocial. Each had their own colored triangle. Jews were then noted by addition of the upside-down triangle, forming the Star of David for instant identification. There were special categories for Polish captives and for Army prisoners (i.e. shirkers, court-martial victims, conscientious objecters, etc.), among others.
