Auschwitz I- Birkenau
Auschwitz had 3 big 'main' camps. They were called Auschwitz I, Auschwitz Birkenau and Auschwitz Monowitz. Monowitz was really a sub camp which was commonly used and when expanded did become as part of the main camps. Out of the lot, Auschwitz Birkenau was the biggest and most feared of as this part was about Extermination when the Final Solution was putted in place.
It had 3 sections. Auschwitz-I, which served as a working camp. Auschwitz II-Birkenau, the death camp. Auschwitz-III, it was used to provide slave labor to the nearby industry.
From early 1942 Auschwitz operated as both. The only other camp that served as both a concentration camp and extermination camp was Majdanek.
Auschwitz was established by Heinrich Himmler.
