Concordat of 1801

The Revolution had not set out to destroy the Catholic Church so much as to nationalise it. The 1790 Civil Constitution of the Clergy made bishops and priests elected officials paid by the state and required an oath of loyalty to the new constitutional order; a majority of bishops and roughly half the parish clergy refused it, splitting French Catholicism into a constitutional church recognised by the state and a refractory church loyal to Rome, with persecution, emigration and, during the Terror, execution falling on clergy on both sides at different points. By the time Napoleon took power in 1799, France had two rival Catholic hierarchies, a large fraction of the population still practising in secret or not at all, and a Papacy that had been driven from Rome twice by French armies.

Napoleon wanted religious peace for practical reasons: an unreconciled Church was a standing source of royalist and counter-revolutionary sentiment, particularly in the west of France, and normal civil life was hard to run without settled parish structures for birth, marriage and death. Negotiations with Pope Pius VII, conducted through intermediaries over many months, produced an agreement signed in July 1801 and promulgated the following Easter, after Napoleon had added, over the Pope's strong objection, a set of unilateral Organic Articles that gave the French state further supervisory power over the Church's public functioning.

The settlement required something genuinely difficult of both sides. Pius VII had to ask the surviving constitutional and refractory bishops alike to resign so that an entirely new episcopate could be appointed jointly, a demand many bishops resisted, and Napoleon had to accept a Church whose loyalty to Rome he could not fully control even as he gained new power over its administration.

The Concordat's terms were narrower than a full restoration. Catholicism was recognised as the religion of the great majority of French citizens, not as the state religion, a distinction that mattered because it preserved the Revolution's principle of religious freedom for Protestants and Jews alongside the practical dominance of the Catholic Church. Confiscated Church property was not returned; in exchange the state agreed to pay clergy salaries, converting the priesthood into salaried civil functionaries in a way that gave the state permanent leverage over appointments and, in practice, over content preached from the pulpit.

The Organic Articles that Napoleon attached without the Pope's agreement went further still, requiring government permission for the publication of any papal document in France and for episcopal correspondence with Rome, provisions the Vatican never formally accepted but that French governments enforced for decades regardless. The result was a durable but uneasy compromise: the Church had public worship, an intact hierarchy and a paid clergy back, and the state had a Church it could supervise rather than an underground one it could not.

The Concordat of 1801 remained the legal basis for church-state relations in France until the Law of 1905 formally separated them, and a modified version of the same regime persists today in the three departments of Alsace-Moselle, which were under German administration in 1905 and never came under the separation law, so a French Concordat negotiated by Napoleon and a Pope still governs clergy salaries in a corner of the French Republic more than two centuries later.
