The Nuremberg Laws (Nurnberger Gesetze) were anti-Semitic laws in Nazi Germany in 1935. The preamble states that the law is intended 'to conserve the purity of German blood. 'Marriages as well as extra-marital relations between Jews and per-sons of German or cognate blood are forbidden. Jews may not employ in their homes female persons of German or cognate blood Under 45 years of age. Jews are not allowed to display the colours of the Reich or to hoist the national flag. Severe penalties will be imposed for violation of this law'.
