Nazi concentration camp badge

File:Wikpedia system of identification German camps.png

The system of badges varied between the camps and in the later stages of World War II 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.{{citation needed|date=November 2024}}

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.{{citation needed|date=November 2024}}

• Blue triangle – foreign forced laborers and emigrants. This category included stateless people ("apatrides"),{{citation needed|date=November 2024}} Spanish refugees from Francoist Spain whose citizenship was revoked and emigrants to countries which were occupied by Nazi Germany or were under German sphere of influence.Gabriele Hammermann, Stefanie Pilzweger-Steiner (2018) KZ-Gedenk·stätte Dachau: Ein Rund·gang in Leichter Sprache. p. 72
• Purple triangle – primarily Jehovah's Witnesses (over 99%) as well as members of other small pacifist religious groups.Johannes S. Wrobel (June 2006). "Jehovah's Witnesses in National Socialist Concentration Camps, 1933–45". 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.'"
• Pink triangle – primarily homosexual men and those who were identified as such at the time (e.g., bisexual men, male prostitutes, and those deemed 'transvestites'{{efn|The concept of an official transgender identity did not exist at this time.

Double-triangle badges resembled two superimposed triangles forming a Star of David, a Jewish symbol.

• Red inverted triangle superimposed upon a yellow one representing a Jewish political prisoner.
• Blue inverted triangle superimposed upon a red one representing foreign forced labour and political prisoner (for example, Spanish Republicans in Mauthausen).{{cite web|url=http://entomelloso.com/de-tomelloso-a-mauthausen/|title=De Tomelloso a Mauthausen|website=entomelloso.com|date=12 January 2017|access-date=27 March 2018}}
• Green inverted triangle superimposed upon a yellow one representing a Jewish habitual criminal.
• Purple inverted triangle superimposed upon a yellow one representing a Jehovah's Witness of Jewish descent.
• Pink inverted triangle superimposed upon a yellow one representing a Jewish "sexual offender", typically a gay or bisexual man.
• Black inverted triangle superimposed upon a yellow one representing an "asocial" or work-shy Jew.
• Voided black inverted triangle superimposed over a yellow triangle representing a Jew convicted of miscegenation and labelled as a {{lang|de|Rassenschänder}} (race defiler).
• Yellow inverted triangle superimposed over a black triangle representing an "Aryan" woman convicted of miscegenation and labelled as a {{lang|de|Rassenschänder}} (race defiler).

Like those who wore pink and green triangles, people in the bottom two categories would have been convicted in criminal courts.

In addition to color-coding, non-German prisoners were marked by the first letter of the German name for their home country or ethnic group. Red triangle with a letter, for example:

• B ({{lang|de|Belgier}}, Belgians)
• E ({{lang|de|Engländer}}, "English"; in practice used for all British)
• F ({{lang|de|Franzosen}}, French)
• I ({{lang|de|Italiener}}, Italians)
• J{{cite web |url=http://www.politika.rs/rubrike/vesti-dana/U-Aushvicu-na-vest-o-oslobodjenju-Beograda.sr.html |title=У Аушвицу, на вест о ослобођењу Београда |author=J. Beoković |website=politika.rs |date=19 October 2009 |language=sr |access-date=26 October 2018 }} ({{lang|de|Jugoslawen}}, Yugoslavs)
• N ({{lang|de|Niederländer}}, Dutch)
• No ({{lang|de|Norweger}}, Norwegian)
• P ({{lang|de|Polen}}, Poles)
• S ({{lang|de|republikanische Spanier}}, Republican Spanish)
• T ({{lang|de|Tscheche}}, Czechs)
• U ({{lang|de|Ungarn}}, Hungarians)
• Z notation next to a black triangle ({{lang|de|Zigeuner}}, Gypsy).

Polish emigrant laborers originally wore a purple diamond with a yellow backing. A letter P (for {{lang|de|Polen}}) was cut out of the purple cloth to show the yellow backing beneath.

Furthermore, repeat offenders ({{lang|de|rückfällige}}, 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.

Many various markings and combinations existed. A prisoner would usually have at least two and possibly more than six.

Limited preventative custody detainee ({{lang|de|Befristete Vorbeugungshaft Häftling}}, 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.

{{lang|de|Erziehungshäftlinge}} (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.

{{lang|de|Polizeihäftlinge}} (police inmates), short for {{lang|de|Polizeilich Sicherungsverwahrte Häftlinge}} (police secure custody inmates), wore either PH in large black letters on a white square or the letter S (for {{lang|de|Sicherungsverwahrt}} – 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 ({{lang|de|Polizeilich Sicherungsverwahrt}}) 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 {{lang|de|Nacht und Nebel}} (night and fog) prisoners had them wear two large letters NN in yellow.

Soviet prisoners of war ({{lang|de|russische Kriegsgefangenen}}) assigned to work camps ({{lang|de|Arbeitslager}}) wore two large letters SU (for {{lang|de|sowjetischer Untermensch}}, meaning Soviet sub-human){{Citation needed|date=October 2019}} 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 Andrey Vlasov's Liberation Army to fight for the Germans.

Labor education detainees ({{lang|de|Arbeitserziehung Häftling}}) wore a white letter A on their black triangle. This stood for {{lang|de|Arbeitsscheuer}} ("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.

{{lang|de|Asoziale}} (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 {{lang|de|Wehrmacht|italic=no}} {{lang|de|Strafbattalion}} (punishment battalion) and SS {{lang|de|Bewährungstruppe}} (probation company) were military punishment units. They consisted of {{lang|de|Wehrmacht|italic=no}} 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 forlorn hopes or cannon fodder. The infamous Dirlewanger Brigade was an example of a regular unit created from such personnel.

A {{lang|de|Strafkompanie}} (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 [attempting to] escape" ({{lang|de|Fluchtverdächtiger}}) wore a red roundel bordered white under their triangle patch. If also assigned to hard labor, they wore the red roundel under their black {{lang|de|Strafkompanie}} roundel.

A prisoner-functionary ({{lang|de|Funktionshäftling}}), or kapo (boss), wore a cloth brassard (their {{lang|de|Kennzeichen}}, or identifying mark) to indicate their status. They served as camp guards ({{lang|de|Lagerpolizei}}), barracks clerks ({{lang|de|Blockschreiber}}) and the senior prisoners ({{lang|de|ältesten}}, meaning elders) at the camp ({{lang|de|lagerältester}}), barracks ({{lang|de|blockältester}}) and room ({{lang|de|stubenältester}}) 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.{{cite book|url=https://books.google.com/books?id=zglu2RvoLmgC&q=%22an+x%22+%22concentration+camp%22+-%22x-men%22+-%22x-ray%22&pg=PA77|title=The Jewish Women of Ravensbrück Concentration Camp|author=Rochelle G. Saidel|year=2006|page=76|publisher=Terrace Books |isbn=9780299198640|access-date=20 May 2013}} 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.

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 Action T4), Soviet POWs and Jehovah's Witnesses. An inverted triangle colored pink would symbolize gay male victims. A non-inverted (base down, point up) triangle and/or a yellow triangle is generally more evocative of the Jewish victims.{{citation needed|date=May 2025}}

In June 2020, the re-election campaign of Donald Trump posted an advertisement on Facebook stating that "Dangerous MOBS of far-left groups are running through our streets and causing absolute mayhem" and identifying them as "ANTIFA", accompanied by a graphic of a downward-pointing red triangle. The ads appeared on the Facebook pages of Donald Trump, the Trump campaign, and Vice President Mike Pence. Many observers compared the graphic to the symbol used by the Nazis for identifying political prisoners such as communists, social democrats and socialists. Many noted the number of ads – 88 – which is associated with neo-Nazis and white supremacists.{{Cite web|last=Breland|first=Ali|title=Nazis put this symbol on political opponents' arms.

As an example of the public outcry against the use of the downward-pointing red triangle, as reported by MotherJones, the Twitter account (@jewishaction),{{Cite Twitter profile|jewishaction}} the account of Bend the Arc: Jewish Action,{{cite web |url=https://www.bendthearc.us/ |title=Home |website=bendthearc.us}} a Progressive Jewish site stated:
