By the mid 15th century the Iroquois Confederacy (or another American Indian state) has become established in roughly the area of what is now New England, southern Quebec and the Maritime Provinces of Canada. It has reached about the same level of technological and military development as Europe and is politically stable.
In 1474 a fleet from there sails to Europe and eventually lands in Portugal, after an average length west-east voyage across the Atlantic by sailing ships. It is intended as a journey of exploration, not of conquest, but the fleet has some soldiers for defensive purposes. There is also a Portuguese speaker who had learnt that language through contact with Portuguese fisherman in the fishing grounds off Newfoundland. What would be the likely reaction of the Portuguese authorities? Alfonso V (1438-1481) was king of Portugal.
What would be the reaction of Aragon, Castile, Granada, and the other European powers?
If that expedition had returned to its native land, there would probably have been subsequent expeditions to Europe.
Would these expeditions have stimulated voyages of discovery/conquest across the Atlantic by European powers before that by Columbus in 1492?
What affect would the American Indian voyages to Europe have had on the course of European and American history?
This is my first post here on this really great discussion forum.
