The French National Archives have created a series of tools that provide directions for researching naturalisations in archives, beginning with key elements of the evolution of nationality law to help situate research within its legal context.
Naturalisation is the process of acquiring a nationality that one does not possess at birth. In France, individuals not born French can acquire nationality in two main ways:
- By declaration: for those entitled “by right” (such as spouses of French citizens or individuals born in France to foreign parents);
- By decree: available, under certain conditions, to individuals residing in France. In this case, the State decides whether to grant nationality after reviewing the application.
A guide offers for an initial search in our aggregator, the FranceArchives portal, which provides an overview of relevant archival holdings.
To locate naturalisation decrees published in the Journal Officiel (the only legally recognised proof of nationality), researchers should consult the holdings of the Bibliothèque nationale de France, accessible via Gallica.
For questions concerning nationality after the Algerian independence specifically, the Noria chatbot (Nouvelle Orientation de Recherche Interactive dans les Archives, New Orientation in Interactive Research in the Archives) can assist with queries related to archives produced by the French administration in Algeria (1830–1962).
