Concentration camps are facilities where large groups of people are detained, often without trial. These camps are typically used during times of war or political unrest to imprison individuals based on their ethnicity, political beliefs, or other characteristics. Conditions in these camps can be harsh, with limited access to food, medical care, and basic human rights. Historically, concentration camps have been associated with events such as the Holocaust, where millions of Jews and other targeted groups were imprisoned and killed. They have also been used in various conflicts around the world, reflecting the darker aspects of human governance and conflict.
