On September 15, 1935, passage of the Nuremberg Laws deprived Jews of German citizenship, and barred them from marrying or having relations with persons of "German or related blood."
Though the Nazis attempted to downplay its persecution of Jews in order to placate the international community during the 1936 Berlin Olympics (in which German-Jewish athletes were not allowed to compete), additional decrees over the next few years disenfranchised Jews and took away their political and civil rights.
In addition to its pervasive anti-Semitism, Hitler's government also sought to establish the cultural dominance of Nazism by burning books, forcing newspapers out of business, using radio and movies for propaganda purposes and forcing teachers throughout Germany's educational system to join the party.
Much of the Nazi persecution of Jews and other targets occurred at the hands of the Geheime Staatspolizei (GESTAPO), or Secret State Police, an arm of the SS that expanded during this period.
