Black triangle (badge)

The inverted black triangle (German: schwarzes Dreieck) was an identification badge used in Nazi concentration camps to mark prisoners designated asozial  [de] ("a(nti-)social")[1][2] and arbeitsscheu ("work-shy").

[1][3] The designation also included disabled individuals, alcoholics, beggars, homeless people, nomads, prostitutes, and violators of laws prohibiting sexual relations between Aryans and Jews.

Female Romani were still deemed asocials as they were stereotyped as petty criminals (prostitutes, kidnappers and fortune tellers).

[8][9] Such groups cite press coverage and government policies, including changes to incapacity benefits and disability living allowance, as the reasons for their campaigns.

[10][11] "The Black Triangle List" was created to keep track of welfare-related deaths due to cuts by the Department for Work and Pensions.
