Concentration camp
Look up concentration camp in Wiktionary, the free dictionary.
A concentration camp is a prison or other facility used for the internment of political prisoners or politically targeted demographics, such as members of national or ethnic minority groups, on the grounds of national security, or for exploitation or punishment.
Prominent examples of historic concentration camps include the Nazi concentration camps (which later morphed into extermination camps), the British confinement of non-combatants during the Second Boer War, the internment of German, Italian, and Japanese Americans by the US during the Second World War, and the Soviet labour camps or gulag.
