In 1935, after the Nazi Party had taken control of the German government, they passed the Nuremberg Laws. The Nazis, led by Adolf Hitler, believed that the "Aryan" race was better than any other races. The Nuremberg Laws made it illegal for "Aryan" and "non-Aryan" people to marry or have sex. At first, the laws were mostly meant to keep "Aryans" from mixing with Jewish people (who the Nazis viewed as an inferior race). However, the Nazis later added "Gypsies, Negroes and their bastard [children]" to the Laws. Aryans who broke these laws could be sent to concentration camps; non-Aryans could be executed. To keep German blood "pure," after World War II began, the Nazis made it illegal for any non-German to marry or have sex with a German person.
