The Huguenots, Henry IV.'s former co-religionists, were deeply pained at the step taken by their leader, and they insisted that their demands must be satisfied. Henry IV., more anxious for the unity and welfare of France than for the triumph of either religious party, determined to put an end to the civil strife by the publication of the Edict of Nantes (1598). The principal articles of the Edict were that the Calvinists should enjoy ******* of worship throughout the greater part of the kingdom, that they should be eligible for all positions of honour and trust in the state, that they should have for their own use the Universities of Montauban, Montpelier, Sedan, and Samur, that the funds for the upkeep of these universities and for the maintenance of their religion should be supplied by the state, and that for a period of eight years they should have possession of some of the principal fortresses. On their side they engaged to break off all alliances with foreigners, to allow Catholic worship to be restored in the places where it had been suppressed, to observe the marriage laws of the Catholic Church, and to abstain from anything that might be regarded as a violation of Catholic holidays. Such concessions were regarded with great disfavour by the Pope, the clergy, and the vast majority of the French people as being opposed to the entire national tradition of France, and it required all the efforts of the king to secure for them the approval of the Paris Parliament (1599). Similarly the Calvinists were not content with what had been conceded to them, nor were they willing to abide by the terms of the Edict of Nantes in so far as to allow the establishment of Catholic worship in the places which were under their control. Their public attacks on the Blessed Eucharist and on the Pope were very irritating to their countrymen, but Henry IV., who was a good king deeply interested especially in the welfare of the lower classes, continued to keep the peace between both parties. His sympathies were, however, with the Protestants of Germany, and he was actually on his way to take part in a war against the Emperor when he was assassinated (1610).
He was succeeded by his son Louis XIII. (1610-43) who was then a boy of nine years. His mother Mary de' Medici, who acted as regent approved the terms of the Edict of Nantes, but the Huguenots relying on the weakness of the government refused to carry out those portions of the Edict favourable to Catholics, and made demands for greater privileges. They rose in rebellion several times especially in the South, entered into alliance with every rebel noble who took up arms against the king, and acted generally as if they formed a state within a state. Cardinal Richelieu who was for years the actual ruler of France (1624-42),[10] inspired solely by political motives, determined to put an end to a condition of affairs that was highly dangerous to the strength and national unity of the kingdom. He saw that it was impossible for France to extend her power so long as there existed at home a well-organised body of citizens prepared to enter into treasonable relations with foreign enemies, and to turn to their own advantage their country's difficulties. His opportunity came when the Huguenots having concluded an alliance with England rose in rebellion (1627). He laid siege to their strongest fortress, La Rochelle, drove back the fleet which England sent to their assistance, and compelled the city to surrender (1628). By this strong measure he put an end to the power of the Huguenots in France and secured peace and unity for the country, while at the same time he treated the conquered with comparative mildness, confirming the Edict of Nantes (Edict of Nimes, 1629), proclaiming a general amnesty, and restoring the leaders of the rebellion to the property and positions they had forfeited.
During the reign of Louis XIV. (1643-1715) the whole tendency of the government was dangerous to the Huguenots. Louis XIV. was determined to make himself absolute ruler of France, and, therefore, he could regard only with the highest disfavour the presence in his territories of a well-organised privileged party like the Huguenots. An opportunity of carrying out his designs came in 1659, when with the approval of the Synod of Montpazier they attempted to negotiate an alliance with England. They were punished with great severity, forbidden to preach in any place without express permission, to attack Catholic doctrines publicly, or to intermarry with Catholics. Converts from Calvinism were encouraged by promises of special concessions.
Owing to the disfavour of the king and the energetic action of the clergy and bishops, whose education and culture at that time stood exceedingly high, large numbers of the Huguenots returned to the Church so that in some places, as for example in Normandy, where once they could boast of considerable influence, the sect became almost extinct.
