I had made the wrong assumption that Protestantism would have been strong in Northern France, while Sothern France would be a Catholic stronghold. But I have found recently that it was the other way round. Why did it happened? Was it because Southern France was farther away from Paris and the Court? Was it because there were remanents of the idea of religious dissent in the South, from the days of Catarism? Was it for some other reason?
