Most of preserved documentary sources about the Jews refer to the city of Maribor and deal with economic activities of the Jewish community, mostly commerce and money-lending, as well as with the social position of the Jews in Styrian towns. He describes the anti-Jewish restrictive policies imposed by the territorial princes from the beginning of the 15lh century onwards, which finally led to their expulsion in the year 1496.
