Nazi concentration camp badges, primarily triangles, were part of the system of identification in German camps. They were used in the
concentration camps A concentration camp is a prison or other facility used for the internment of political prisoners or politically targeted demographics, such as members of national or ethnic minority groups, on the grounds of national security, or for exploit ...
in the German-occupied countries to identify the reason the prisoners had been placed there. The triangles were made of fabric and were sewn on jackets and trousers of the prisoners. These mandatory badges of shame had specific meanings indicated by their colour and shape. Such emblems helped guards assign tasks to the detainees. For example, a guard at a glance could see if someone was a convicted criminal (green patch) and thus likely of a tough temperament suitable for '' kapo'' duty. Someone with an escape suspect mark usually would not be assigned to work squads operating outside the camp fence. Someone wearing an F could be called upon to help translate guards' spoken instructions to a trainload of new arrivals from France. Some historical monuments quote the badge-imagery, with the use of a triangle being a sort of visual shorthand to symbolize all camp victims. The modern-day use of a

Badge coding system

The system of badges varied between the camps and in the later stages of
World War II World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the wo ...
the use of badges dwindled in some camps and became increasingly accidental in others. The following description is based on the badge coding system used before and during the early stages of the war in the Dachau concentration camp, which had one of the more elaborate coding systems. Shape was chosen by analogy with the common triangular road hazard signs in Germany that denote warnings to motorists. Here, a triangle is called inverted because its base is up while one of its angles points down.

''Religion, State & Society''. Vol. 34. No. 2. pp. 89–125. "The concentration camp prisoner category 'Bible Student' at times apparently included a few members from small Bible Student splinter groups, as well as adherents of other religious groups which played only a secondary role during the time of the National Socialist regime, such as Adventists, Baptists and the New Apostolic community (Garbe 1999, pp. 82, 406; Zeiger, 2001, p. 72). Since their numbers in the camps were quite small compared with the total number of Jehovah's Witness prisoners, I shall not consider them separately in this article. Historian Antje Zeiger (2001, p. 88) writes about Sachsenhausen camp: 'In May 1938, every tenth prisoner was a Jehovah's Witness. Less than one percent of the Witnesses included other religious nonconformists (Adventists, Baptists, pacifists), who were placed in the same prisoner classification.'" *

). Polish emigrant laborers originally wore a purple diamond with a yellow backing. A letter P (for ) was cut out of the purple cloth to show the yellow backing beneath. Furthermore, repeat offenders (, meaning recidivists) would receive bars over their stars or triangles, a different colour for a different crime. * A political prisoner would have a red bar over their star or triangle. * A professional criminal would have a green bar. * A foreign forced laborer would not have a blue bar (as their impressment was for the duration of the war), but might have a different coloured bar if they were drawn from another pool of inmates. * A Jehovah's Witness would have a purple bar. * A homosexual or sex offender would have a pink bar. * An asocial would have a black bar. * Roma and Sinti would usually be incarcerated in special sub-camps until they died and so would not normally receive a repeat stripe. Later in the war (late 1944), to save cloth Jewish prisoners wore a yellow bar over a regular point-down triangle to indicate their status. For instance, regular Jews would wear a yellow bar over a red triangle while Jewish criminals would wear a yellow bar over a green triangle.


Special marks

Many various markings and combinations existed. A prisoner would usually have at least two and possibly more than six. Limited preventative custody detainee (, or BV) was the term for general criminals (who wore green triangles with no special marks). They originally were only supposed to be incarcerated at the camp until their term expired and then they would be released. However, when the war began they were confined indefinitely for its duration. (reformatory inmates) wore E or EH in large black letters on a white square. They were made up of intellectuals and respected community members who could organize and lead a resistance movement, suspicious persons picked up in sweeps or stopped at checkpoints, people caught performing conspiratorial activities or acts and inmates who broke work discipline. They were assigned to hard labor for six to eight weeks and were then released. It was hoped that the threat of permanent incarceration at hard labor would deter them from further action. (police inmates), short for (police secure custody inmates), wore either PH in large black letters on a white square or the letter S (for – secure custody) on a green triangle. To save expense, some camps had them just wear their civilian clothes without markings. Records used the letter PSV () to designate them. They were people awaiting trial by a police court-martial or who were already convicted. They were detained in a special jail barracks until they were executed. Some camps assigned (night and fog) prisoners had them wear two large letters NN in yellow. Soviet prisoners of war () assigned to work camps () wore two large letters SU (for , meaning Soviet sub-human) in yellow and had vertical stripes painted on their uniforms. They were the few who had not been shot out of hand or died of neglect from untreated wounds, exposure to the elements, or starvation before they could reach a camp. They performed hard labor. Some joined

's Liberation Army to fight for the Germans. Labor education detainees () wore a white letter A on their black triangle. This stood for ("work-shy person"), designating stereotypically "lazy" social undesirables like Gypsies, petty criminals (e.g. prostitutes and pickpockets), alcoholics/drug addicts and vagrants. They were usually assigned to work at labor camps. (anti-socials) inmates wore a plain black triangle. They were considered either too "selfish" or "deviant" to contribute to society or were considered too impaired to support themselves. They were therefore considered a burden. This category included pacifists and conscription resisters, petty or habitual criminals, the mentally ill and the mentally and/or physically disabled. They were usually executed. The (punishment battalion) and SS (probation company) were military punishment units. They consisted of and SS military criminals, SS personnel convicted by an Honor Court of bad conduct and civilian criminals for which military service was either the assigned punishment or a voluntary replacement of imprisonment. They wore regular uniforms, but were forbidden rank or unit insignia until they had proven themselves in combat. They wore an uninverted (point-upwards) red triangle on their upper sleeves to indicate their status. Most were used for hard labor, "special tasks" (unwanted dangerous jobs like defusing landmines or running phone cables) or were used as

s or cannon fodder. The infamous Dirlewanger Brigade was an example of a regular unit created from such personnel. A (punishment company) was a hard labor unit in the camps. Inmates assigned to it wore a black roundel bordered white under their triangle patch. Prisoners "suspected of ttempting toescape" () wore a red roundel bordered white under their triangle patch. If also assigned to hard labor, they wore the red roundel under their black roundel. A prisoner-functionary (), or '' kapo'' (boss), wore a cloth brassard (their , or identifying mark) to indicate their status. They served as camp guards (), barracks clerks () and the senior prisoners (, meaning elders) at the camp (), barracks () and room () levels of camp organization. They received privileges like bigger and sometimes better food rations, better quarters (or even a private room), luxuries (like tobacco or alcohol) and access to the camp's facilities (like the showers or the pool). Failure to please their captors meant demotion and loss of privileges and an almost certain death at the hands of their fellow inmates. Detainees wearing civilian clothing (more common later in the war) instead of the striped uniforms were often marked with a prominent X on the back. This made for an '' ersatz'' prisoner uniform. For permanence, such Xs were made with white oil paint, with sewn-on cloth strips, or were cut (with underlying jacket-liner fabric providing the contrasting color). Detainees would be compelled to sew their number and (if applicable) a triangle emblem onto the fronts of such X-ed clothing. File:13cwik.jpg, F on red triangle (French political enemy) on

Postwar use

Triangle-motifs appear on many postwar memorials to the victims of the Nazis. Most triangles are plain while some others bear nationality-letters. The otherwise potentially puzzling designs are a direct reference to the identification patches used in the camps. On such monuments, typically an inverted (point down, base up) triangle (especially if red) evokes all victims, including also the non-Jewish victims like Poles and other Slavs, communists, homosexuals, Roma and Sinti (see Porajmos), people with disability (see
