Auschwitz concentration camp was the largest camp established by the Nazis. The camp was in fact three main camps with different functions but with one main purpose: to force the prisoners to work. This well-known camp’s construction started in May of 1940 in Poland, which was annexed in 1939. Auschwitz would eventually be separated into three separate camps, Auschwitz I, Auschwitz II ( Auschwitz- Birkenua) and lastly Auschwitz III (Auschwitz- Monowitz).1
