Step-by-step explanation:
They rounded up anyone of Jewish descent and packed them into concentration camps. Any german citizen who was found harboring Jewish people were punished severely. These concentration camps were brutal as they experimented on their wrongfully imprisoned people and killed many in gas chambers. The bodys piled up so high they would either throw them in the incinerator or dig abnormally large holes to throw them in. Auschwitz was a well know concentration camp located in Poland. Many believe the worst of the worst crimes were committed there. It is known a doctor resided there who favored experimenting (torturing) on twins.
