He's hot as fuck so based on that fact I'd like to think he is real....It's based on fact to an extent. I don't think there's any evidence as to Ragnar actual being a living person. Everything he is mentioned in is either folk lore or mythical stories.
But hey I could be wrong.

His deformed son becomes King and Rollo was definetly a real person.
All in all, makes a good change to the usual BS tv shows.
