On 15 September 1935, the Nazis introduced the Nuremberg Race Laws. These racist laws were directed against the Jews in Germany and essentially stripped them of their civil rights.
Based on family lineage, the laws determined who was Jewish and who was not. People with three or four Jewish grandparents were considered Jewish. Jews were no longer considered citizens and therefore could not claim certain civil rights, could no longer vote and could not work for the government.
Another section of the Nuremberg Laws was called the 'Law for the protection of German blood and German honour'. Under this law, marriages between Jews and Germans were forbidden. Moreover, Jews were not permitted to employ female citizens of German blood under the age of 45 as domestic workers.
