Ragnar Lothbrok and the Vikings in the Middle Ages

R Ragnar Lothbrok is almost certainly the most famous name in early Viking history. He's supposed to have been one of the leaders in the great attack on Paris in the middle eight forties where those guys were slaughtered by the Vikings. Some people will suggest he'd ever existed at all but like so many figures in ancient or medieval history he was turned into something like a demigod over time.
