Protestantism in France

Protestantism in France has existed in its various forms, starting with Calvinism and Lutheranism since the Protestant Reformation. John Calvin was a Frenchman, as were numerous other Protestant Reformers including William Farel, Pierre Viret and Theodore Beza, who was Calvin's successor in Geneva. Peter Waldo (Pierre Vaudes/de Vaux) was a merchant from Lyon, who founded a pre-Protestant group, the Waldensians. Martin Bucer was born a German in Alsace, which historically belonged to the Holy Roman Empire, but now belongs to France.

Hans J. Hillerbrand in his Encyclopedia of Protestantism claims the Huguenots reached as much as 15% of the French population on the eve of the St. Bartholomew's Day massacre, declining to 10-12% by the end of the 16th century, and further after heavy persecution began once again with the revocation of the Edict of Nantes by Louis XIV.

Protestants were granted a degree of religious freedom following the Edict of Nantes, but it ceased with the Edict of Fontainebleau. The Protestant minority was persecuted, and a majority of Huguenots fled the country, leaving isolated communities like the one in the Cevennes region, which survives to this day.

According to a 2020 survey, Protestants made up 3% of the French population. A renewed interest in Protestantism has been brought by numerous Evangelical Protestants, while the membership of Calvinist and Lutheran churches has stagnated; many of the latter two confessions have merged into the United Protestant Church of France.
