The purple triangle was a concentration camp badge used by the Nazis to identify Bibelforscher (Bible Students), the German name for Jehovah’s Witnesses in Nazi Germany. A small number of Adventists, Baptists and pacifists (less than one percent) were also identified by the badge. Nazism opposed unorthodox-Christian religious minorities (along with Jews), but made the Bible Students the object of particularly intense persecution, including such extensive incarceration that a distinct badge was assigned to them.
