One of the posts over in the Preventing the Hapsburg Genetic Collapse that dominated the Seventeenth Century TL, came up with an idea of perhaps of widening the pool of potential non-relative candidates by having the European monarch marry into established Kingdoms in the Americas, Africa and Asia. As far as I understand it no effort was made atleast during the intial decades of the Age of Exploration to legitimatize the newly discovered kingdoms? Since this is before the development of the social construction of Racism, what would it take for the European Houses to believe that the best way to bring these territories into their own realm was by perhaps by marriage? Would the technological gap between the The Americas, Africa and Asia have to be smaller?,Coupled maybe with the phenomenon of having the early attempts to conquer such kingdoms ultimately fail? Is there any specific one POD that could be used to get an precedent established for such a thing as the Spanish marrying one of the Tawantinsuya princess? I can't wait to see what everyone comes up with.
