France is simultaneously the "eldest daughter of the Church" — a title acknowledging its role as the first major German kingdom to convert to Catholicism under Clovis in 496 — and the European country that has gone furthest to banish religion from public life. The principle of laïcité (secularism) is foundational to French republican identity: the state is neutral on religious matters, guarantees freedom of belief, and forbids religious expression in state institutions including schools. This framework, born from centuries of religious conflict, now intersects with the presence of Europe's largest Muslim community to produce some of the continent's most intense debates about identity, integration, and freedom.
Historical Background
Catholic France
France was Catholic for fourteen centuries — from Clovis's baptism (traditionally dated 496 or 498) to the Revolution. The Church was integral to every aspect of life: education, healthcare, marriage, burial, the calendar, the moral framework. Cathedral-building was the supreme collective endeavour. The medieval French Church produced some of Christianity's greatest thinkers: Abelard, Bernard of Clairvaux, Thomas Aquinas (at the University of Paris).
The Wars of Religion
The sixteenth-century Wars of Religion (1562–1598) between Catholics and Huguenots (French Calvinists) devastated France. The St. Bartholomew's Day Massacre (1572) killed thousands of Protestants in Paris and across the country. Henri IV's Edict of Nantes (1598) granted Huguenots freedom of worship — the first such law in Europe. Louis XIV revoked it in 1685, driving hundreds of thousands of Protestants into exile.
The Revolution and Dechristianisation
The Revolution attacked the Church with revolutionary violence. Church lands were nationalised. Religious orders were dissolved. The Civil Constitution of the Clergy (1790) subordinated the Church to the state. During the Terror, cathedrals were converted to Temples of Reason, church bells melted for cannon, and the calendar itself was secularised (the ten-day week replaced the seven-day week, eliminating Sunday). Napoleon restored relations with Rome via the Concordat of 1801.
The 1905 Law
The Loi de séparation des Églises et de l'État (Law of Separation of Church and State) (1905) is the legal foundation of French secularism. Its key provisions:
- Freedom of conscience: The Republic guarantees freedom of belief
- No state religion: The Republic does not recognise, pay salaries to, or subsidise any religion
- State neutrality: Public institutions and servants must be religiously neutral
- Church property: Existing churches became state property; religious organisations may use them free of charge
The 1905 law did not apply to Alsace-Moselle (then part of Germany), which retains the Concordat system — the state pays salaries of Catholic, Protestant, and Jewish clergy, and religious education is taught in public schools.
Religion in France Today
Catholicism
France remains culturally Catholic — the calendar, the architecture, the holidays, the traditions of baptism, marriage, and burial — but practice has collapsed. Regular Mass attendance has fallen from over 90% in 1950 to approximately 5% today. Many churches outside Paris are nearly empty. Yet 60% of French people still identify as Catholic, and major events (Christmas, Easter, pilgrimages to Lourdes) retain cultural significance.
Islam
France's Muslim community — estimated at 5–6 million — is predominantly of North African origin (Algerian, Moroccan, Tunisian), reflecting colonial history and postwar immigration. Islam is the second religion of France and the fastest growing, though precise figures are unavailable because census data on religion is not collected.
The intersection of laïcité (secularism) and Islam has produced France's most divisive social debates: the 2004 ban on "conspicuous religious symbols" in public schools (targeting the hijab), the 2010 ban on face coverings in public spaces (targeting the niqab and burqa), and recurring controversies over mosque construction, halal food, and the integration of religious practice into secular public life.
Judaism
France has Europe's largest Jewish community (~450,000–600,000), concentrated in Paris and Marseille. French Judaism has deep roots — Jewish communities in Provence and Alsace predate the medieval period. But the Dreyfus Affair (1894–1906), the Vichy regime's active collaboration in the Holocaust (76,000 French Jews deported, fewer than 3,000 returned), and recent antisemitic attacks have created a community that is both culturally central and persistently anxious. Emigration to Israel has increased significantly since 2012.
Protestantism
Approximately 3% of the population, mainly Reformed (Calvinist) in the Cévennes and southwest, and Lutheran in Alsace. French Protestantism, forged in the Wars of Religion, has historically been associated with republican values, intellectual life, and banking.

Hours, fares, and festival weeks move. A 2024 caption is not a 2026 desk. Religion in France sits in a country that is easy to over-plan and easy to under-prepare. The society layer is where visitors collect names. This page is the opposite: what to do first, what to skip, and which sibling guide holds the rest.
France rewards a slow unit. One arrondissement, one valley, one appellation, one park trail. The photograph of five landmarks in five days is a real holiday, and it is also a queue with a passport. If you only have three nights, spend two of them in the same bed. The third night is for a train, not a third hotel.
Working a visit
Practical France is sockets (Type E/F, 230 V), tap water that is safe, pharmacies that are the real clinic for minor trouble, and a lunch hour that still closes a village. Cards work in cities. Cash still opens some park kiosks, some island boats, and some market stalls that have never seen contactless. A lightweight adapter belongs in the personal item, not the hold.
We will not write as if every reader is on a gap year, or as if every reader is in a palace hotel. We will not flatten 'the south' into one climate. We will not treat a strike day, a jour férié, or a Tuesday museum closure as a personality quirk of the French. They are calendars. Check them. Then use Religion in France as a pin, not as scripture.
Cross the five guides instead of cloning them. La Porte holds trains and the first week. La Terre holds weather and park gates. L'Esprit holds museum Tuesdays and the Revolution. La Table holds the market morning and the wine list. Le Moteur holds the Tour, the working week, and why August is empty in Paris and full on the coast.
