By June 1940, Nazi Germany had occupied Paris. France was cut in two: north of the demarcation line was the German-occupied zone, to the south was a zone headed by Marshal Pétain, whose seat of government was in the central spa town of Vichy. The Vichy regime very quickly, and without pressure from the Germans, passed the first Jewish laws. With the first of these, prefects in the southern zone had the right to lock up foreign Jews and Jewish refugees in camps.
