"For Aryans only." The racial theories are being put into practice within a few years after the Nazis assume power: With the "Law for the Protection of German Blood and German Honor" passed at Nuremberg in 1935, intermarriage between "Aryans" and members of "inferior" races like Jews, Slavs or Gypsies became prohibited. Only people of German "blood" remained citizens with full political rights.
