The Loiret department gets its name from the eponymous river, a resurgence of the Loire. Created during the French Revolution in 1790, it is mainly derived from the former province of Orléanais. Its prefecture, Orléans, is inseparable from the figure of Joan of Arc, who liberated the city in 1429.


Loiret is bordered by seven departments: the Essonne, the Seine-et-Marne, the Yonne, the Nièvre, the Cher, the Loir-et-Cher and the Eure-et-Loir. 


Historically, the department is divided into several natural regions with strong identities: the Beauce (the granary), the Gâtinais (around Montargis), the Sologne (hunting and mystery lands) and the Loire Valley, classified as a UNESCO World Heritage site. For genealogists, understanding this geography is essential because the professions (Loire rivermen, winemakers, Beauce plowmen) and population movements depend directly on it.

🌎 Migrations in Loiret


Loiret has always been a transit and melting pot area, located on the strategic axis between the Paris Basin and southern France.

  • 17th - 18th centuries: during the Ancien Régime, Loiret was a commercial crossroads. The Loire was the "nation of rivers," and many families of river workers traveled between Orléans and Nantes. 

    Like other provinces, Orléans contributed to the settlement of Canada. It is estimated that several dozen colonists left this region to settle in Quebec.


  • 19th century: with the industrial revolution and the arrival of the railway (Paris-Orléans line in 1843), movements accelerated.

    Loiret experienced a strong exodus to Paris. Young rural residents from Beauce and Gâtinais left farms to become domestic workers or factory workers in the capital.
    Conversely, Beauce attracted seasonal workers (harvesters) sometimes coming from poorer departments in central France (Creuse, Auvergne).

  • 20th century: the last century saw the arrival of populations fleeing conflicts or coming to rebuild the country.

    Following the Retirada, Loiret welcomed thousands of Spanish refugees. Camps were set up, notably in Saint-Cyprien and later in local structures like the camp in Cepoy. Many settled permanently in the department.

    After 1945, the industrial development of Orléans and the Montargis conurbation (Hutchinson factories, pharmaceutical sector) attracted a significant foreign workforce: Portuguese, Maghrebi and Italian workers joined the ranks of construction and industry workers.

    A unique fact, Orléans hosted the general headquarters of NATO forces in France. This presence generated specific marriages and population flows with the United States.
