Ghettos and camps refer to the segregated living areas and detention facilities established by Nazi Germany during World War II, primarily for the purpose of isolating, controlling, and ultimately exterminating Jewish populations and other targeted groups. Ghettos were often overcrowded urban areas where Jews were forced to live under deplorable conditions, while concentration camps were sites of imprisonment where forced labor, inhumane treatment, and mass murder took place. These locations exemplified the systematic approach of the Holocaust aimed at annihilating entire communities.
