France gradually strengthened its central power during the late middle ages and early modern times. But what if Protestantism/the Hugenotes became a stronger force than in OTL? In OTL there was a civil war in the latter half of the sixteenth century.What if the Hugenots managed to create a lasting separate state in the south of France? In OTL, during the Thirty Years' War, France supported German Protestants in order to weaken the Habsburg emperor. Is it possible to see a scenario where the Habsburgs would support the Hugenots in order to weaken the king of France (I suppose here that France is still much stronger than the Hugenot state, so that the Habsburgs would see France as more of a threat than the Hugenots in Occitania).
NB! In order to avoid mass murder of butterflies; such a state would obviously influence European politics in many ways, so please do not assume that there would neccessarily be a Thirty Years' War starting in 1618 and ending in 1648, although a similar war might occur. In fact, this scenario encourages an even larger war, since large parts of OTL France would be more directly involved as a scene of war.
