Departments of France - History

History

The first French departments, in the sense of territory, were proposed in 1665 by Marc-René d'Argenson, and served as administrative areas purely for the Ponts et Chaussées ("Bridges and Highways", the infrastructure administration).

Before the French Revolution, France gained territory gradually through the annexation of a mosaic of independent entities. By the close of the Ancien Régime, it was organised into provinces. During the period of the Revolution, these were dissolved, partly in order to weaken old loyalties.

The modern departments, as all-purpose units of the government, were created on 4 March 1790 by the National Constituent Assembly to replace the provinces with what the Assembly deemed a more rational structure. Their boundaries served two purposes:

• Boundaries were deliberately 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 any settlement in the country was within a day's ride of the capital of the department. This was a security measure, intended to keep the entire national territory under close control. This measure was directly inspired by the Great Terror, during which the government had lost control of many rural areas far from any centre of government.

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.

The number of departments, initially 83, was increased to 130 by 1809 with the territorial gains of the Republic and of the First French Empire (see Provinces of the Netherlands for the annexed Dutch departments). Following Napoleon's defeats in 1814-1815, the Congress of Vienna returned France to its pre-war size; the number of departments was reduced to 86, as three of the original departments had 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 their alphabetical order.

The departments of Moselle, Bas-Rhin, and most of 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 remained French, however, and became known as the Territoire de Belfort. 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.

The reorganisation of Île-de-France (1968) and the division of Corsica (1975) added six more departments, raising the total to 96. Counting the five overseas departments (French Guiana, Guadeloupe, Martinique, Réunion and Mayotte) the total comes to 101 departments. In 2011, the overseas collectivity of Mayotte became the 101st department.
