I never believe any "official" versions of history. There are always three sides to every story, the winner's, the loser's and the truth. There is always an alternative version of what happened that can be researched.
Now that my rant is over, let me answer the question at hand. I have always had a fascination with Germanic history. I also love the history of the "New World". Which by the way, contrary to the Euro centric bias of most people, pre-dates 1492 by a long, long time. How can someone "discover" a land with hundreds of thousands inhabitants already there? There is evidence of limited African-South American trade at least a hundred years before Columbus. Never mind the Vikings and the fact that there where people living in South America far to early for the Bering land bridge to be the only way that people populated the the western hemisphere.
