As if being economically fragile and in constant fear of war wasn’t enough, the Franks were pagans, their beliefs dating back to the Celtic iron-age and forming the basis of European folklore and fairytales. The Romans had ended 280 years of Christian persecution, now the Franks were free to resurrect it.
The foundations of a strong and wealthy society in Normandy were in place, though it’s doubtful the average Christian peasant would have seen it. It wasn’t dubbed the Dark Ages for no reason. The Dark ages, early middle ages or early medieval times, they’re all the same, would last for 500 years until 1000AD.
The persecution of Christians finally ended in 496 when King Clovis’s Christian wife convinced him to convert. From then on the Catholic Christian community began to thrive.
