In 1939, at the outbreak of the Second World War, the French government decided to intern citizens of the Reich. In the region, theformer tile factory at Les Milles was transformed into an internment camp for these "enemy subjects", who were made to live in very precarious conditions. Yet some of them were ordinary citizens, sometimes even anti-fascists, who had left their country to flee Nazism.
Less than a year later, the armistice was signed and the Vichy regime transformed the site into a concentration camp for "undesirables", where Jews and foreigners were locked up. The Les Milles camp quickly became overcrowded, and the living conditions of the internees deteriorated as they had to endure hunger, overcrowding, vermin and disease.
