Auschwitz was divided into three main camps—Auschwitz I, Auschwitz II (Birkenau), and Auschwitz III (Monowitz)—to serve different purposes. Auschwitz I was primarily a administrative center and a concentration camp for political prisoners, while Auschwitz II (Birkenau) was designed as a large extermination camp to facilitate mass killings. Auschwitz III (Monowitz) functioned as a labor camp, where inmates were forced to work in factories supporting the German war effort. This division allowed the Nazis to efficiently manage the systematic genocide and exploitation of prisoners.

Auschwitz (Konzentrationslager Auschwitz) was the largest of the German Nazi concentration and extermination camps. Located in southern Poland, it took its name from the nearby town of Oświęcim (Auschwitz in German), situated about 50 kilometers west of Kraków and 286 kilometers from Warsaw. Following the German occupation of Poland in September 1939, Oświęcim was incorporated into Germany and renamed Auschwitz. Auschwitz opened as a concentration camp in May 1940 and from October 1941 expanded into a large group of camps, with Auschwitz I, II and III on or near the main site and a further 35 sub-camps.
