Edict of Fontainebleau
Huguenots (French Reformed Protestants) fought a series of wars in France with Catholics, resulting in millions of deaths and the Edict of Fontainebleau in 1685 which revoked their freedom of religion. In 1565, several hundred Huguenot shipwreck survivors surrendered to the Spanish in Florida, believing they would be treated well. Although a Catholic minority in their party was spared, all of the rest were executed for heresy, with active clerical participation.
