History of the Jews in Besançon
The beginnings of the history of the Jews in Besançon go back to the Middle Ages, a period during which the Jews settled in the city attracted by its activity as a commercial place. The community was founded at the end of the 14th century and, due to its status as a free imperial city, Besançon remained one of the only territories in present-day France to tolerate Jews after their expulsion from the kingdom of France in 1394.
