The government of Nazi Germany gradually took more and more rights away from the Jews from the time that they came to power. There were more than 400 laws passed under the Nazis that limited Jewish rights in some way.
The first major law to discriminate against Jews was passed in 1933. It made it so that Jews could no longer work for the government. Later laws made it illegal for Jews to participate in a variety of other professions. There were also laws that limited the number of Jews who were allowed to attend universities.
Perhaps the most famous anti-Jewish laws were the Nuremberg Laws of 1935. These laws did such things as denying Jews the right to be German citizens. They also banned marriages or any sexual relations between Jews and non-Jews.
German laws discriminated against Jews in many, many ways before World War II brought on the Holocaust.
