Edict of Fontainebleau
His measures were also badly timed; the French Edict of Fontainebleau in October 1685 revoked tolerance for French Huguenots and in the next five years, some 200,000–400,000 left France, 40,000 of whom settled in London. The killing of 2,000 Vaudois Protestants in 1686 and French expansion under Louis XIV combined to reinforce fears Protestant Europe was threatened by a Catholic counter-reformation.
