Q: Louis XIV gained the throne in 1643 and acted increasingly aggressively to force the Huguenots to convert. At first he sent missionaries, backed by a fund to financially reward converts to Catholicism. Then he imposed penalties, closed Huguenot schools and excluded them from favored professions. Escalating, he instituted dragonnades, which included the occupation and looting of Huguenot homes by military troops, in an effort to forcibly convert them. In 1685, he issued the Edict of Fontainebleau, revoking the Edict of Nantes and declaring Protestantism illegal.[citation needed]
