Question

What did the Nuremberg laws do?

Answer 1

These laws took German citizenship away from Jews and outlawed both marriage and sex between Jews and non-Jews.

Answer 2

The Nuremberg Laws were actually a set of two laws: the Reich Citizenship Law and the Law for the Protection of German Blood and Honor.

The Reich Citizenship Law stripped Jews of their German citizenship and introduced a new distinction between "Reich citizens " and "nationals."

the Law for the Protection of German Blood and Honor -

Marriages between Jews and citizens of German or kindred blood are forbidden. Marriages concluded in defiance of this law are void, even if, for the purpose of evading this law, they were concluded abroad.

Sexual relations outside marriage between Jews and nationals of German or kindred blood are forbidden.

Jews will not be permitted to employ female citizens of German or kindred blood as domestic servants.

Jews are forbidden to display the Reich and national flag or the national colors.
