Black triangle (badge)

The inverted black triangle (German: schwarzes Dreieck) was an identification badge used in Nazi concentration camps to mark prisoners designated asozial ("asocial") and arbeitsscheu ("work-shy"). The Roma and Sinti people were considered asocial and tagged with the black triangle. The designation also included alcoholics, beggars, homeless people, nomads, prostitutes, and violators of laws prohibiting sexual relations between Aryans and Jews. Women also deemed to be anti-social included nonconformists.
