The city of Paris started mobilizing for war in September 1939, when Nazi Germany and the Soviet Union
attacked Poland, but the war seemed far away until 10 May 1940, when the Germans attacked France and quickly defeated the French army. The French government departed Paris on 10 June, and the Germans occupied the city on 14 June. During the occupation, the French government moved to Vichy, and Paris was governed by the German military and by French officials approved by the Germans. For Parisians, the occupation was a series of frustrations, shortages and humiliations. A curfew was in effect from 9 p.m. to 5 a.m.; at night, the city went dark. Rationing of food, tobacco, coal and clothing was imposed from September 1940. Every year the supplies grew more scarce and the prices higher.
