- Jews were not the only group of people who were sent to the extermination camps. Other groups of people were sent to forced-labor camps. Groups other than Jews that were sent to the camps were political prisoners, such as communists or socialists, common criminals, gypsies, Jehovah's witnesses, homosexuals, and captured Soviet soldiers were used as forced laborers. These different groups were categorized using colored triangles. Political prisoners wore red triangles, common criminals wore green, gypsies wore black, Jehovah's witnesses wore purple, and homosexuals wore pink. There were also letters placed on the triangles to show where the prisoners had came from. For example, F stood for French and P was for Polish. Jews were by far treated the worst out of all of the different groups of people. A lot of Jews were just sent straight to the extermination camps if they were seen to be unfit for work in the labor camps.
- Political prisoners, Jehovah's witnesses and homosexuals were also targeted groups. However, they were sent to the camps as punishment for their actions. Since the conditions in the camps were so cruel, most of the members of these groups ended up dying anyways due to starvation, disease, exhaustion or brutal treatment
