Departments of France
The National Constituent Assembly decreed the creation of departments on the 26th of February 1790. This decision followed a decree from the 4th of August 1789 that eliminated provincial privileges. A subsequent decree dated the 22nd of December 1789 provided for the termination of existing provincial governments. Letters patent issued in January 1790 finalized this administrative overhaul. The revolutionary leader Abbé Sieyès championed this project to replace historical provinces with rational geographical boundaries. He believed these new units would strengthen national unity by erasing old cultural loyalties. Most departments were named after physical features like rivers or mountains rather than historical territories. For example, the department of Gironde takes its name from the estuary of the same river. The boundary between any settlement and the department capital was designed to be reachable within a day's ride on horseback. This security measure ensured the entire territory remained under close control from Paris. By 1793, these departments functioned as transmission belts for policies enacted in the capital. The system dissolved the mosaic of independent entities that had characterized France before the Revolution.
Each department is administered by an elected body called a departmental council. Before April 2015, these councils were known as general councils. A president leads each council through a six-year term determined by universal suffrage. Local services of state administration are traditionally organized at the departmental level where a prefect represents the government. The prefect is appointed directly by the President of the French Republic. From 1800 until 1982, the prefect served as the chief executive of the department. Since 1982, the prefect retains only powers not delegated to the department councils. Their role has largely been limited to preventing local policy from conflicting with national policy. The main areas of responsibility for councils include managing social welfare allowances and junior high school buildings. They also oversee technical staff, local roads, and rural buses. In certain cases, they contribute to municipal infrastructures. Regions have gained importance since the 2000s, leading some department-level services to merge into region-level services. As of 2025, there were 34,746 communes in France governed by municipal councils. Paris serves as both a commune and a department within this structure.
The number of departments initially stood at 83 when created in 1790. This figure increased to 130 by 1809 following territorial gains of the First French Empire. Napoleon's defeats between 1814 and 1815 led to the Congress of Vienna returning France to its pre-war size. The number of departments was reduced to 86 after these losses. Three original departments had been split during this period. France acquired the County of Nice and Savoy in 1860, creating three new departments including Alpes-Maritimes. The department of Bas-Rhin and parts of Meurthe, Moselle, Vosges, and Haut-Rhin were ceded to Germany in 1871. A small part of Haut-Rhin remained French and became known as the Territoire de Belfort. In 1922, this territory became France's 90th department. Reorganization of Île-de-France in 1968 and division of Corsica in 1975 added six more departments. By 2011, Mayotte joined earlier overseas departments like Guadeloupe, Martinique, and Réunion which were all created in 1946. The total reached 101 departments in the French Republic. In 2015, the Urban Community of Lyon split from Rhône to form the Métropole de Lyon. As of 2019, Corse-du-Sud and Haute-Corse remain administrative departments though they no longer hold full territorial collectivity status. Most departments are assigned a two-digit number called the Official Geographical Code.
The median land area of a department in mainland France is approximately 5,300 square kilometers. This size is two-and-a-half times larger than ceremonial counties in England or preserved counties in Wales. It is slightly more than three-and-a-half times the median area of a county in the United States. At the 2001 census, the median population was 511,000 inhabitants. This figure represents 21 times the median population of a US county but less than two-thirds of an English or Welsh ceremonial county. Most departments have an area between 4,000 and 8,000 square kilometers. Their populations typically range between 320,000 and one million people. Gironde stands as the largest department by area while Paris holds the smallest title. Nord contains the most populous community with 2,550,000 residents. Lozère remains the least populous with only 74,000 inhabitants. The Le Havre-Marseille line marks where 60% of the French population lives to the east. The prefecture is generally located roughly at the geographical center of the department. This location was determined according to travel time on horseback from the periphery within 24 hours. Mâcon serves as the capital of Saône-et-Loire despite Chalon-sur-Saône being the largest city.
Departmental Councils are elected using a two-round system that drastically limits fringe party chances. After the 1992 election, the left held a majority in only 21 of the 100 departments. By the 2011 election, the left dominated 61 of those same 100 departments. Mayotte became a department after this election cycle began. Political preferences vary significantly across regions due to this voting structure. Divers Centre represents independents or members of the Democratic Movement. Divers Droite denotes independent conservatives while Divers Gauche indicates independent left-wing politicians. The Socialist Party and Union for a Popular Movement remain major forces in local governance. The two-round electoral system ensures moderate parties support fringe candidates if necessary during runoff rounds. These maps cannot serve as useful resources for voter preference analysis because of this structural limitation. Frédéric Lefebvre spoke in December 2008 about fusing departments with regions as a matter for immediate discussion. Édouard Balladur and Gérard Longuet refuted these claims shortly thereafter through their committee work. The Attali Commission recommended eliminating the departmental level within ten years in January 2008. President François Hollande proposed abolishing departmental councils by 2020 in 2014 before scrapping the reform project.
The French model shaped administrative divisions in many countries including former colonies. Departments were established in Algeria from 1848 until independence in 1962. These units were supposed to be assimilated into France sometime in the future. Similar structures appeared in Haiti between 1795 and 1800 under the name South cardinal direction. Saint Lucia received a department named Sainte-Lucie covering the island of St Lucia. Mauritius and Seychelles were organized under Île de France during colonial rule. Pondicherry, Karikal, Yanaon, and Mahé formed part of Indes-Orientales in India. West Bengal included Chandernagore as an administrative unit. During the Napoleonic Empire, departments existed across conquered European territories like Belgium and Germany. The Department of Dyle covered Brussels while Escaut encompassed Ghent. Roman territories became departments such as Rome itself or Trasimène around Spoleto. Italian regions like Piedmont-Sardinia saw departments including Marengo and Pô. The system influenced Spain's territorial division in 1822 and again in 1833 which forms the basis of present-day provinces with minor modifications. Overseas departments have three-digit numbers instead of the standard two digits used elsewhere. Monaco uses the alphanumeric code 98 within this global framework.
