Departments of France

History

Main article: Territorial evolution of France

The first French territorial departments were proposed in 1665 by Marc-René d'Argenson to serve as administrative areas purely for the Ponts et Chaussées (Bridges and Highways) infrastructure administration.

Before the French Revolution, France gained territory gradually through the annexation of a mosaic of independent entities. By the end of the Ancien Régime it was organised into provinces. During the Revolution they were dissolved, partly in order to weaken old loyalties. The National Constituent Assembly decided to create a more uniform division into departments (département) and districts in late 1789. The process began on 4 August 1789 with the elimination of provincial privileges, and a 22 December 1789 decree (with letters patent in January 1790) provided for the termination of the provincial governments.

The modern department system, as all-purpose units of the government, was decreed on 26 February 1790 (with letters patent on 4 March 1790) by the National Constituent Assembly. Their boundaries served two purposes:

• Boundaries were chosen to break up France's historical regions in an attempt to erase cultural differences and build a more homogeneous nation.
• Boundaries were set so that every settlement in the country was within a day's ride of the capital of a department. This was a security measure, intended to keep the entire national territory under close control.

The old nomenclature was carefully avoided in naming the new departments. Most were named after an area's principal river or other physical features. Even Paris was in the department of Seine. Savoy, during its temporary occupation, became the department of Mont-Blanc. The provinces continued to exist administratively until 21 September 1791.

The number of departments, initially 83, had been increased to 130 by 1809 with the territorial gains of the Republic and of the First French Empire. Following the defeats of Napoleon in 1814–1815 the Congress of Vienna returned France to its pre-war size and the number of departments was reduced to 86 (three of the original departments having been split). In 1860 France acquired the County of Nice and Savoy, which led to the creation of three new departments. Two were added from the new Savoyard territory, while the department of Alpes-Maritimes was created from Nice and a portion of the Var department. The 89 departments were given numbers based on the alphabetical order of their names.

The department of Bas-Rhin and parts of Meurthe, Moselle, Vosges and Haut-Rhin were ceded to the German Empire in 1871 following France's defeat in the Franco-Prussian War. A small part of Haut-Rhin, however, remained French and became known as the Territoire de Belfort; the remaining parts of Meurthe and Moselle were merged into a new Meurthe-et-Moselle department. When France regained the ceded departments after World War I, the Territoire de Belfort was not reintegrated into Haut-Rhin. In 1922 it became France's 90th department. Likewise the Lorraine departments were not changed back to their original boundaries, and a new Moselle department was created in the regained territory, with slightly different boundaries from the pre-war department of the same name.

The reorganisation of Île-de-France in 1968 and the division of Corsica in 1975 added six more departments, raising the total in Metropolitan France to 96. By 2011, when the overseas collectivity of Mayotte became a department, joining the earlier overseas departments of the Republic (all created in 1946) – French Guiana, Guadeloupe, Martinique and Réunion – the total number of departments in the French Republic had become 101. In 2015 the Urban Community of Lyon was split from Rhône to form the Métropole de Lyon, a sui generis entity, with the powers of both an intercommunality and those of a department on its territory, formally classified as a "territorial collectivity with particular status" () and as such not belonging to any department. As of 2019 Corse-du-Sud and Haute-Corse are still administrative departments, although they no longer have the status of departmental "territorial collectivities": region and department functions have been managed by a "single territorial collectivity" since 2018.

Despite the intention to avoid the old nomenclature, often the names of pre-1790 provinces remained in use. For example, the name of Berry, though no longer having an official status, remains in widespread use in daily life.

General characteristics

Main article: Administrative divisions of France

Government and administration

The departmental seat of government is known as the prefecture (préfecture) or chef-lieu de département and is generally a town of some importance roughly at the geographical centre of the department. This was determined according to the time taken to travel on horseback from the periphery of the department. The goal was for the prefecture to be accessible on horseback from any town in the department within 24 hours. The prefecture is not necessarily the largest city in the department: for instance, in Saône-et-Loire department the capital is Mâcon, but the largest city is Chalon-sur-Saône. Departments may be divided into arrondissements. The capital of an arrondissement is called a subprefecture (sous-préfecture) or chef-lieu d'arrondissement.

Each department is administered by a departmental council (conseil départemental), an assembly elected for six years by universal suffrage, with the President of the Departmental Council as executive of the department. Before 1982, the chief executive of the department was the prefect (préfet), who represents the Government of France in each department and is appointed by the President of the French Republic. The prefect is assisted by one or more sub-prefects (sous-préfet) based in the subprefectures of the department. Since 1982, the prefect retains only the powers that are not delegated to the department councils. In practice, their role has been largely limited to preventing local policy from conflicting with national policy.

The departments are further divided into communes, governed by municipal councils. As of 2025, there were 34,746 communes in France. In the overseas territories, some communes play a role at departmental level. Paris, the country's capital city, is a commune as well as a department.

In mainland France (metropolitan France, excluding Corsica), the median land area of a department is 5965 km2, which is two-and-a-half times the median land area of the ceremonial counties of England and the preserved counties of Wales and slightly more than three-and-half times the median land area of a county of the United States. At the 2001 census, the median population of a department in continental France was 511,000 inhabitants, which is 21 times the median population of a United States county, but less than two-thirds of the median population of a ceremonial county of England and Wales. Most of the departments have an area of between 4,000 and 8,000 km2 (1500 to 3000 sq. mi), and a population between 320,000 and 1 million. The largest in area is Gironde (10,000 km2), while the smallest is the city of Paris (105 km2). The most populous is Nord (2,550,000) and the least populous is Lozère (74,000).

Numbering

The departments are numbered: their two-digit numbers appear in postal codes, in INSEE codes (including "social security numbers") and on vehicle number plates. Initially the numbers corresponded to the alphabetical order of the names of the departments, but several changed their names and some have been divided, so the correspondence became less exact. Alphanumeric codes 2A and 2B were used for Corsica while it was split but it has since reverted to 20. The two-digit code "98" is used by Monaco. Together with the ISO 3166-1 alpha-2 country code FR, the numbers form the ISO 3166-2 country subdivision codes for the metropolitan departments. The overseas departments have three digits.

Relation to national government

Originally, the relationship between the departments and the central government was left somewhat ambiguous. While citizens in each department elected their own officials, the local governments were subordinated to the central government, becoming instruments of national integration. By 1793, however, the revolutionary government had turned the departments into transmission belts for policies enacted in Paris. With few exceptions, the departments had this role until the early 1960s.

Political party preferences

These maps cannot be used as a useful resource of voter preferences, because Departmental Councils are elected on a two-round system, which drastically limits the chances of fringe parties, if they are not supported on one of the two rounds by a moderate party. After the 1992 election, the left had a majority in only 21 of the 100 departments; after the 2011 election, the left dominated 61 of the 100 departments. (Mayotte only became a department after the election.)

Future

The removal of one or more levels of local government has been discussed for some years; in particular, the option of removing the departmental level. Frédéric Lefebvre, spokesman for the UMP, said in December 2008 that the fusion of the departments with the regions was a matter to be dealt with soon. This was soon refuted by Édouard Balladur and Gérard Longuet, members of the committee for the reform of local authorities, known as the Balladur Committee.

In January 2008, the Attali Commission recommended that the departmental level of government should be eliminated within ten years.

Nevertheless, the Balladur Committee has not retained this proposition and does not advocate the disappearance of the departments, but simply "favors the voluntary grouping of departments", which it suggests also for the regions, with the aim of reducing the number of regions to 15. This committee advocates, on the contrary, the suppression of the cantons.

Current departments

Each department has a coat of arms and a flag with which it is commonly associated, though not all are officially recognised or used.
