Okay. Not Exactly.
But could an ambiguously similar society have developed on the eastern coast of North America, in the hypothethical situation that a permanent settlement had been established by transatlantic navigators some centuries before the colonial powers in our timeline?
For example, a Vinland that managed to survive and expand along the coast until it grew so big that splintered into smaller feudal states? Or mayhaps the European nobles managed to escape en-masse from some much more powerful and succesful steppe horde that somehow penetreated into the heartland of their old continent?
