During the Nazi regime, there were several different factors that allowed for the persecution and extermination of minority groups. This includes:
Political factors
The rise in power of Adolph Hitler was the most significant political factor that allowed for the persecution of Jews and other minority groups. His feelings about these groups were expressed in the book he wrote (Mein Kempf) 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.
Social factors
A series of written and spoken propaganda convinced German citizens that the root of their 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.
