In September 1935, the Nuremberg Laws were enacted, prohibiting marriages between Jews and people of Germanic extraction, extramarital sexual relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law stated that only those of German or related blood were defined as citizens; thus, Jews and other minority groups were stripped of their German citizenship. A supplementary decree issued in November defined as Jewish anyone with three Jewish grandparents, or two grandparents if the Jewish faith was followed. By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews emigrated to the United States, Palestine, Great Britain, and other countries.
