Basically, what if Louis-Auguste de Bourbon, XVI of France had died in 1785, shortly after the birth of Louis-Charles, Duc de Normandy. Would this help put off the revolution or would the revolution change to be about removing the evil advisors of Louis-Joseph Xavier François, XVII of France. And would France benefit from an extended regency rather than a period of misrule and slow change, with the regency first under Louis-Joseph then Louis-Charles. Who takes the regency, the Duc de Orleans or perhaps the Count of Artois? Where do they marry off Marie-Therese in these circumstances, and does she have children with a different husband? And what happens to their mother, Marie Antoinette?
