The Bretons aren't British or English, British aren't a race they are a union of English, welsh, Irish and Scottish the Bretons are French. They are based on the real life Bretons (not to be confused with Britons). Bretons are from Brittany in northern France they were celts who came originally from what is now England, as all celts were pushed out of England by the Anglo saxons into ireland , Wales and northernmost France. The English descended from the Anglo Saxons who came from areas that are now in Germany. And the altmer in my opinion are more like Nazi Germany as in they believe they are superior to all races and think they should rule all. The Nord's I agree are clearly Scandinavian, Orcs are Mongolian, Imperials are obviously roman possibly slightly British in the fact that the empire was at its peak the biggest empire in history. Redguards I'd say the moors, woodelfs I'm unsure cause I think part of they're religion involves cannibalism so native american would be out of it maybe tribes of haiti?, khajiit Arabian maybe, argonians possibly certain parts of Africa with the tropical swamps and in part because they are downtrodden and were once seen as slaves and dark elves im not really sure.
