A concentration camp is a place where people who are politically against the leaders of a region, people who are of a certain race or religion, non-military prisoners of war, or other people are imprisoned.

The first concentration camps were used by the British in the Boer War in Africa in the 1890s. Concentration camps gained notoriety after 1936 when Nazi Germany's leader, Adolf Hitler, thought of certain groups of people as "unclean" or "undesirable". Such people were sent to these camps to be gassed, shot, or sometimes worked to death. The gas chambers reportedly killed up to 20,000 people a day, towards the end of World War II. Over half of the people who died in the holocaust died at the concentration camps, mostly at Auschwitz.
