In October 1685 Louis XIV signed the Edict of Fontainebleau revoking the Edict of Nantes. It forbade exercising the Protestant faith and any migrating of Protestants. Pastors were granted a fortnight to convert or flee into exile.
It resulted in clandestine departures to Refuge countries and in conversions which were not always sincere. Some newly converted avoided Catholic obligations for instance, and met in clandestine assemblies. The repression was organised.
