The Nuremberg Laws, as they became known, did not define a "Jew" as someone with particular religious beliefs
The Nuremberg Laws, did not define a "Jew" as someone with particular religious beliefs. But anyone who had a few Jewish grandparents was defined as a Jew, whether or not that person identified as a Jew or belonged to the Jewish religious community.
The laws excluded German Jews from Reich citizenship and prohibited them from marrying or having sexual relations with persons of "German or related blood."
The most serious actions against Jews were outside of any law, but the law itself was still pretty bad
The National archive stated that the laws mad it legal but the actual attack on Jews began 2 years before thew law
What made the laws so bad was it took the basic rights of Jews, such as the right to vote in political elections, and prohibited marital and extra-marital relations between Jewish and non-Jewish Germans
