Numerous internment camps and concentration camps were located in France before, during and after World War II. Beside the camps created during World War I to intern German, Austrian and Ottoman civilian prisoners, the Third Republic (1871–1940) opened various internment camps for the Spanish refugees fleeing the Spanish Civil War (1936–1939). Following the prohibition of the French Communist Party (PCF) by the government of Édouard Daladier, they were used to detain communist political prisoners. The Third Republic also interned German anti-Nazis (mostly members of the Communist Party of Germany, KPD).

Then, after the 10 July 1940 vote of full powers to Marshal Philippe Pétain and the proclamation of the État français (Vichy regime), these camps were used to intern Jews, Gypsies, and various political prisoners (anti-fascists from all countries). Vichy opened up so many camps that it became a full economic sector, to the extent that historian Maurice Rajsfus writes: "The quick opening of new camps created jobs, and the Gendarmerie never ceased to hire during this period." In any case, most of these camps were closed definitively after the liberation of France at the end of World War II. Some "regroupement camps" were however used during the Algerian War (1954–1962). Several of these were then used to intern harkis (Algerians who had fought on the French side) after the 19 March 1962 Évian Accords. Finally, the Camp de Rivesaltes in the Pyrénées-Orientales and the camp of Bourg-Lastic in the Puy de Dôme were also used to intern Kurdish refugees from Iraq in the 1980s.

The first internment camps were opened during the First World War (1914–1918) to detain civilian prisoners (mainly German, Austro-Hungarian and Ottoman). These prisoners were detained in Pontmain in the department of Mayenne, Fort-Barreaux in Isère, in the military camp of Graveson (Bouches-du-Rhône), in Frigolet[1] near Tarascon (Bouches-du-Rhône), Noirlac (Abbey) (Cher), and Ajain(Creuse).

Other internment camps were used for Armenians in the 1920s-1930s (Mirabeau camp, Victor Hugo camp and Oddo Camp in Marseille); Gypsies after the 1912 Act on nomadism (for instance in the Royal Saltworks at Arc-et-Senans, but also in iron mines in the Manche and other disaffected industrial centers in Mayenne, in the Manche, in Loire-Atlantique, in the Sarthe, in the Maine-et-Loire, etc.).

The most infamous internment camps before World War II were used to intern the Spanish Republican refugees and military personnel during the Spanish Civil War. In 2 weeks in January and February 1939 around 500,000 men, women and children crossed the border. These were interned mostly in camps in the Roussillon Province, such as the Camp de concentration d'Argelès-sur-Mer although internment camps for defeated Spanish Republicans were established in all of French territory, even in Brittany, in the north-west of France. These camps were located in:

To these camps must be added the camps for the German prisoners in 1939 (sometimes overlapping with those above), and those of the Colonial Empire, not well known in Europe.

Furthermore, the Chilean poet Pablo Neruda, who had been named Consul in Paris for Immigration, organized the transportation to Chile of 2,200 Spanish refugees who had been detained in the camps on board the Winnipeg, which departed on 2 August 1939, and arrived in Valparaíso at the beginning of September 1939.

After 1940 when the Nazi Germany divided France in occupied and free zone, the camps were also used to imprison Jews, Gypsies, and sometimes gays, and the original prisoners were used as forced labor to make the camps larger.
