During World War II, the Nazis undertook to exterminate all the Jews in Europe. If they managed to kill all the Jews in Europe, they would kill all the Jews in the world. To accomplish this work, they established concentration camps across Europe (“Concentration”). These camps were places of torture and held Jews as if they were some kind of plague.

Auschwitz I was the main camp and is where the Nazis performed medical experiments on Jews and where the camp housed some of its prisoners. Auschwitz II was the part of the camp that did nothing but kill. By the end of the Holocaust, more than a million Jews were in Auschwitz and died; a large proportion of these deaths were due to this second Auschwitz camp.
