There were several different factors that allowed for the persecution and extermination of minority groups. For example: Hitlers feelings about these groups were expressed in the book he wrote and his speeches to the German people. Since he had absolute control over the government and military, he could have individuals he didn't like killed at any time he would like. Also keep in mind economic problems were the Jewish people. These posters and speeches were spread so often that people started to believe them. This allowed for the extermination and persecution of individuals in Germany, as average citizens saw nothing wrong with getting rid of these people who were causing the problems.
