Etymologically they amount to the same. Norse is just Dutch for "people from the north," which is precisely what Norsk means.I say I don't like indentify norway to viking , I think norsemen as have been stated is far better
If you mean from the time of the accession of James VI and I, sure, but in the Middle Ages, at the time of Robert the Bruce, Scotland was absolutely independent from England, and hostile or at least unfriendly towards England more often than not. Up until the High Middle Ages, when the Normans moved in, Scotland was far more closely linked with Ireland than England. That's not to say that Civ6's design that strangely leans heavily on British Scotland doesn't feel terribly out of place, but Scotland absolutely was a completely independent commonwealth ("state" is a misleading term for the Middle Ages or Early Modern period) until James I and VI succeeded to the throne of England upon the death of Elizabeth I, nor were Anglo-Scottish relations particularly cozy even then. I'm not thrilled that they chose Scotland--its design is more British than Norman and more Norman than Celtic, making it a dubious choice for what they clearly hoped would be a "Celtic" civ--Ireland or Gaul would have been much better choices in that regard--but they certainly could have given Scotland a design more in line with what they were aiming for*.about independence .. we have no to discuss things like sovereign and political unions... but the fact that there was independence sentiment in Scotland (and today is still there) and foreign enemies tried to use it .. does mean that Scotland and England were independent states in real terms..
*More or less, at least. The Gaels were always marginalized in Scotland, which means that Scotland was never going to be the ideal choice for a more specific Celtic civ.
