The third and perhaps most telling factor adding to the overall confusion about Boulle's parentage was that in October 1685 (a mere 8 years after his marriage), Louis XIV renounced the Edict of Nantes and declared Protestantism illegal with the Edict of Fontainebleau. All Protestant ministers were given two weeks to leave the country unless they converted to Catholicism.Louis XIV ordered the destruction of Huguenot churches, as well as the closure of Protestant schools. This made official the persecution of Protestants already enforced since 1681 and it led to around 400,000 fleeing the country.
