What was the main effect of the Nuremberg laws?

The main affect of the Nuremberg laws was that the Jews no longer had certain freedoms, liberties, and rights they did before the laws were created. This ultimately led to Kristallnacht and much worse experiences.

The Nuremberg laws were designed to make Jewish people second class citizens - well, non-citizens, really. And it worked. Many of the atrocities that happened to the Jewish people were actually not against the law in Germany at that time. They were still very wrong and cruel.
