concentration camp

A location in which a regime detains civilians who are perceived to threaten that regime without judicial review. Though the practice of “concentration” of populations with a specific profile has been used by various countries since the 19th century, it has become most widely associated with Nazi policies during World War II.

The Nazis operated an expansive system of concentration camps between 1933-1945, in which vast numbers of prisoners were detained, murdered, and exploited as slave laborers. An estimated two million concentration camp prisoners died.
