Over the remainder of Louis XIII's reign, and especially during the minority of Louis XIV, the implementation of the Edict varied year by year. In 1661 Louis XIV, who was particularly hostile to the Huguenots, started assuming control of his government and began to disregard some of the provisions of the Edict. In 1681 he instituted the policy of dragonnades, to intimidate Huguenot families to convert to Roman Catholicism or emigrate. Finally, in October 1685, Louis issued the Edict of Fontainebleau, which formally revoked the Edict and made the practice of Protestantism illegal in France. The revocation of the Edict had very damaging results for France. While it did not prompt renewed religious warfare, many Protestants chose to leave France rather than convert, with most moving to Great Britain, Prussia, the Dutch Republic and Switzerland. At the dawn of the 18th century, Protestants remained in significant numbers in the remote Cévennes region of the Massif Central. This population, known as the Camisards, revolted against the government in 1702, leading to fighting that continued intermittently until 1715, after which the Camisards were largely left in peace.
