 The Edict of St. Germain, promulgated 36 years before by Catherine de Médici, had granted limited tolerance to Huguenots but was overtaken by events, as it was not formally registered until after the Massacre of Vassy on 1 March 1562, which triggered the first of the French Wars of Religion.The later Edict of Fontainebleau, which revoked the Edict of Nantes in October 1685, was promulgated by Louis XIV, the grandson of Henry IV.It drove an exodus of Protestants and increased the hostility of Protestant nations bordering France.
