Answer:
The Jews were stripped of their German citizenship. Hitler and Josef Goebbels used propaganda to give Germans (or Aryans) the view that Jews were subhuman ('untermensch') and that they didn't belong in Germany.
An example of this discrimination against Jews is Kristallnacht. Many Jewish synagogues, businesses and homes were organised by the SS or be attacked and destroyed, in retaliation for a Jew assassinating the German Ambassador to France.
