The Nuremberg laws were broken into four different sections. The first stated that marriage between Jewish blood and German blood was prohibited. This law was put into place to "protect the German blood" (The Nuremberg Laws). The second section states that sexual relations of any kind between the Jewish and the Germans was also not allowed. This law also was put into effect to "protect the German blood".
Section 3 of the Nuremberg laws stated that you may not employ anyone under the age of 45 who is of German or related blood or is a woman (ushmm.org). Section 4 of the laws stated that Jews were forbidden to fly the reich flag. It also stated they weren't allowed to display the reich colors in any way. Another thing that section 4 of the Nuremberg laws stated was that, although they cannot display the reich flag or colors, Jews were allowed to display their own Jewish flag and colors. The exercise of this right was protected by the state (ushmm.org).
