Vichy Holocaust collaboration timeline

Led first by Philippe Pétain, the Vichy regime that replaced the French Third Republic in 1940 chose the path of collaboration with the Nazi occupiers. This policy included the Bousquet-Oberg accords of July 1942 that formalized the collaboration of the French police with the German police. This collaboration was manifested in particular by anti-Semitic measures taken by the Vichy government, and by its active participation in the genocide.
