Prisoners of the Camps
Identifying the Prisoners: Badges of the Concentration Camps
Nearly all prisoners selected for forced labor in concentration camps were registered by the SS and given a number. Many were photographed.
Beginning in 1937–38, the SS created a standardized system of marking camp prisoners with triangular badges, the color of which identified the reason for their incarceration. Jews were marked by adding a yellow triangle beneath the first to form a Star of David.
