Auschwitz concentration camp

Auschwitz concentration camp was a network of Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It consisted of Auschwitz I (the original camp), Auschwitz II–Birkenau (a combination concentration / extermination camp), Auschwitz III–Monowitz (a labor camp to staff an IG Farben factory), and 45 satellite camps.

Auschwitz I was first constructed to hold Polish political prisoners, who began to arrive in May 1940. The first extermination of prisoners took place in September 1941, and Auschwitz II–Birkenau went on to become a major site of the Nazi "Final Solution to the Jewish question".
