Now I know that this is not a terribly large WI, and not likely to cause any major change but it is still one that has been nagging at me for some time.
In november of 1870 the revolutionary government in Spain elected the second son of the King of Italy, Amadeo, the Duke of Aosta, as king of of spain. Things did not go well for Amadeo and by early 1873 he was forced to abdicate the throne, not through and major lack of competance, but rather by the chaos that was Spain at the time.
So, what if Amadeo had managed to hold on to the reins of power and forge a new ruling dynasty.
