In 1685, Louis XIV of France issued the Edict of Fontainebleau revoking the Edict of Nantes, which had enshrined the confessional coexistence of Catholics and Huguenots in law since 1598. Though emigration was forbidden by law, many French Protestants succeeded in leaving France. Most of them settled in the neighbouring European countries, though some also settled overseas.
