How did the Holocaust happen?

laws were gradually implemented which both demonized groups which Hitler did not like and allowed the persecution of those groups to be legal.

How did group, location, and World War II events impact an individual’s experience?

Group – Jews, Socialists, Communists, Jehovah’s Witnesses, Roma, homosexuals and the mentally ill were persecuted while those who did not fall into the above categories were left alone.
Location – Crimes were committed against those in Nazi-controlled countries, while those in countries under the control of the Allies were left alone. In addition, the specific concentration camp where one was incarcerated impacted the way a person was treated. Auschwitz was one of the worst.
World War II events – after D-Day, persecution decreased dramatically, most likely because the Germans were busy fighting.
