Dividing people up into valuable and less valuable individuals was one of the foundations of Hitler’s ideology. The terror against people who were considered racially or socially inferior or opponents of the regime including Jews, Sinti and Romanies, homosexuals, the disabled, communists, social democrats and Christians came in many different guises - political opponents were beaten up and taken into protective custody, they were intimidated, dispossessed and expelled, and mass murdered, Jews in particular.
