As far as I can see almost every nation (race) in TES is based on a real-world civilization. Cyrodiil is based on the Roman Empire, Skyrim on the Vikings (Norse), Hammerfell seems to be based on Arabic, desert dwelling people, and Highrock on Britain. I can't really see what the Kajiit, Argonians and Mer are based on. Any ideas?
I think the Altmer are more britiany (the accents), but I dont know much about Breton culture, so I wouldn't know. Dont know much about Summerset isle either, besides them being a bunch of snobs. I thought bretons were french?
