In OTL, Alfonso was used as a pawn by the nobles of Castile against his brother Henry IV. When he died from either the plague or being assassinated, they then moved to position Isabella to be Queen instead of Juana, Henry's daughter, leading to the Second War of Castilian Succession. So what if Alfonso doesn't die from either the plague or being assassinated? Would there still be a war between him and Juana? I know Henry had tried to make them become engaged to unite the claims but I don't really see that happening.
Who would be a potential bride for Alfonso XII? Would he be able to reverse the decentralization of his brother as Isabella did in OTL? He died at fourteen so we don't know much about how he would have ruled in any case but I could see him being similar to his elder sister.
