Purple triangle

The purple triangle was a concentration camp badge used by the Nazis to identify Bibelforscher (the German name for Jehovah's Witnesses) in Nazi Germany. A small number of Adventists, Baptists, Bible Student splinter groups, and pacifists (combined 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.
