Auschwitz-Birkenau-Plaszow Concentration Camps | Poland
The Auschwitz concentration camp was a complex of more than 40 Nazi concentration camps 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 and administrative headquarters in Oświęcim; Auschwitz II–Birkenau, a combined concentration and extermination camp three kilometers away in Brzezinka. Auschwitz was Nazi Germany’s largest concentration camp and extermination camp. Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews. Also among the dead were some 19,000 Roma who were held at the camp until the Nazis gassed them on July 31, 1944—the only other victim group gassed in family units alongside the Jews. The Poles constituted the second largest victim group at Auschwitz, where some 83,000 were killed or died.
