Revocation of the Edict of Nantes
Also called: Edict of Fontainebleau, Dragonnades
In 1685 Louis XIV revoked the Edict of Nantes with the Edict of Fontainebleau and outlawed Protestantism; hundreds of thousands of Huguenots fled to the Netherlands, England, Prussia and elsewhere.

Seeking “one king, one law, one faith”, Louis XIV forced Huguenots to convert by billeting dragoons in their homes (the dragonnades), and in October 1685 revoked the Edict of Nantes by the Edict of Fontainebleau. Some 200,000 Huguenots, many of them merchants and craftsmen, left for the Netherlands, England, Switzerland and Prussia, which issued an edict welcoming them. France lost skills and capital, while the countries that took them in saw their industries grow. Around the same time in Joseon, King Sukjong’s repeated changes of faction brought the Westerners and Southerners to power in turn.
