I was wondering about what seems to me to be a fairly obvious question, but I'm guessing that since I don't know too much about 19th century politics, it's probably more complex than that.
If Ferdinand d'Orléans, Prince Royal de France were to survive his *unfortunate carriage accident that resulted in his death, could the July Monarchy last? I'm asking because the way I understood it, Louis-Philippe's abdication meant leaving the power in the hands of a minor (the Cte de Paris) under the regency of his mother (if one follows traditional French regencies) or of the senior male of the royal family, the Duc de Nemours (if one follows the "new" regency law brought in under the last years of Louis XVI). The problem was that his mother was Protestant, and Nemours was "an avowed conservative". From what I know, the Prince Royal was not only liberal but he was progressively minded.
Could Ferdinand save the July Monarchy if he'd lived?
* I say unfortunate since those who supported the senior house of Bourbon probably toasted it similarly to the Jacobites' little gentleman in velvet.
