Scandinavians colonize Minnesota? That's not original tee hee hee.
But this time around, they won't be assimilated.
Control of Helluland, Markland, and Vinland pretty much ensures the ability for the Nordic people to expand their control into the St. Lawrence river and into the Great Lakes. The French meanwhile would slowly make their way up the eastern seaboard, colonizing what would had been more or less the Thirteen Colonies that would make up the core states for the United States of America. If you read the fictional sources, it implies the creation of an independent Francophone state a couple of centuries ahead but that is all that I am revealing concerning it.
Now I have several ideas. I can cover the beginnings of Muslim incursions into the Carribean or cover what has the potential of being an important event for the Ottoman empire or concentrate on the Incas.
Any status on the battle of Tenochtitlan would have be saved for later.
