And here's my other scenario: I've been thinking about other potential colonists in the Americas, with a divergence point around the usual time of the Age of Discovery (15th century). Anyway, what if Columbus found the backing for his expedition in his (presumed) home town of Genoa? Could travel to the New World have fallen into the hands of the Republic of Genoa? I know at the time the Republic was barely recovering from losses incurred by conflicts with the Ottomans, and presumably could have viewed the New World (Ameriga? Vesspucciland?) as a potential money-making venture. Did Genoa have enough of a martial spirit to have inspired their own versions of the Conquistadores? How long would it take before the implications of the Columbus voyage became apparent to the courts of Europe? What's the likelihood of rival colonists in the Amerigas, and who would they be?
