A place at which persons are confined or imprisoned, typically under harsh conditions, usually because of their membership within a particular persecuted group. Although the term has been used as early as the twentieth century in the Spanish American and Boer Wars, today it is most commonly used to refer to the Nazi camps of World War II, which held millions of Jews as well as other persecuted minorities including homosexuals, Gypsies, and Poles, and at which at least six million died under horrendous conditions.
The term “American concentration camps” is used to refer to the relocation centers or internment camps that housed Americans of Japanese ancestry and Japanese nationals who were forcibly removed from their homes during World War II.
