The Auschwitz concentration camp was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II–Birkenau, a concentration and extermination camp three kilometers away in Brzezinka; Auschwitz III–Monowitz, a labor camp in Monowice created to staff an IG Farben synthetic-rubber factory; and dozens of other subcamps.
Approximately, 1.3 million people were shipped to the camps with an estimate of more than 1.1 million being exterminated.
