Aryanization was the Nazi term for the seizure of property from Jews and its transfer to non-Jews, and the forced expulsion of Jews from economic life in Nazi Germany, Axis-aligned states, and their occupied territories. It entailed the transfer of Jewish property into "Aryan" or non-Jewish hands.

The Nuremberg Laws were antisemitic and racist laws that were enacted in Nazi Germany on 15 September 1935, at a special meeting of the Reichstag convened during the annual Nuremberg Rally of the Nazi Party. The two laws were the Law for the Protection of German Blood and German Honour, which forbade marriages and extramarital intercourse between Jews and Germans and the employment of German females under 45 in Jewish households; and the Reich Citizenship Law, which declared that only those of German or related blood were eligible to be Reich citizens. The remainder were classed as state subjects without any citizenship rights. A supplementary decree outlining the definition of who was Jewish was passed on 14 November, and the Reich Citizenship Law officially came into force on that date. The laws were expanded on 26 November 1935 to include Romani and Black people. This supplementary decree defined Romani people as "enemies of the race-based state", the same category as Jews.
