Explain one reason that the Nazi German regime undertook the Holocaust against European Jews. Describe one earlier intellectual development that contributed to Nazi ideology.

Within Nazi Germany, everyone did not support Nazism or the Nazi regime to the same degree and to the extent suggested by iconic photographs and film footage of Nazi-staged spectacles. As Doris Bergen writes, “Smooth functioning of the system did not require all Germans—or even most—to share every tenet of Nazi ideology. Enough enthusiasts could always be found to stage enormous public shows of support such as the annual Nazi Party rallies. On a day to day basis, the Nazi regime only needed most people to obey the law, try to stay out of trouble, and promote their own interests as best they could under the current circumstances.”
