Hitler came to power with the ideology of anti-semitism. He had a pseudo-scientific view of constructing an 'Aryan nation'. The Jews were the worst sufferers in Hitler's regime. Hitler stereotyped them as the killers of Christ and usurers. They were pushed to live in marked areas called Ghettos. The Nazis dehumanised Jews by comparing them to vermins, parasites, pests, lice, and rats. The Nazis also propagated that the ethnic cleansing of Jews would liberate Germany. Hitler brutally committed mass killings through various techniques such as putting the Jews in gas chambers and disinfection areas.
