During its entire existence, slightly over 400 thousand people were registered at Auschwitz as prisoners - including 131 thousand women. The two largest groups of prisoners were Jews - about 200 thousand - and Poles, some 140 thousand. Since Germans established the camp in spring 1940 with the members of Polish resistance and intelligentsia in mind, Poles dominated in the camp at first. This situation began to change in March 1942, when mass deportations of Jews for extermination began. Dr. Piotr Setkiewicz, the head of the Auschwitz Memorial Research Center, talks about the situation of Polish and Jewish prisoners in the camp.
