Extermination camps were facilities established by Nazi Germany during World War II for the systematic murder of millions of people, primarily Jews, as part of the Holocaust. These camps were designed specifically for mass killings, employing methods such as gas chambers and mass shootings to eliminate those deemed undesirable by the Nazi regime. The existence of extermination camps underscores the horrific nature of the Holocaust and the extreme measures taken by the Nazis to carry out their genocidal policies.
