Ok I'm fiddling around with an idea in my head at the moment and need some help. How would France developed if they find a way to reach a peace in the aftermath of the War of the Fifth Coalition in which Napoleon dies at the tail end of that war and Talleyrand is able to get the House of Bourbon restored to the throne but on French terms. In this effort he is able to get 1802 borders in Europe kept by the French Kingdom but at the cost of some colonies overseas. How would the French go about developing their nation and would they down the line become an even more industrialized nation?
If Napoleon dies like this, he goes down a great national hero, having defeated every coalition ranged against him. Whether it's Joseph, Eugène or someone else succeeding him, his régime will survive in some fashion, at least initially. I don't see how Louis XVIII takes the throne. He's an émigré who's been out of the country for almost 20 years and living in enemy nations.
I dont know if this is possible. France at this point doesn't have colonies worth trading really, IOTL neither Britain nor Sweden really wanted Guadaloupe and it's about all France has that's worth trading. Look at OTL and what colonies Britain kept after the Napoleonic Wars- SOME of the Dutch colonies... they didn't keep the Philippines, Indonesia, or 80% of what they conquered (probably not even 90%). This is the time between the two French Colonial Empires, after the French and Indian Wars and before the conquests in West Africa. And Britain's goal was always to have a balance of power on the Continent to keep any one power from being able to keep the British out of trading with Europe; so is Britain going to allow France to be halfway to recreating the Charlemagne Holy Roman Empire? And what happens to the Holy Roman Empire in this TL?
If I'm reading the OP correctly, France ITTL is trading away
all of its conquests beyond the 1802 borders, plus giving away some colonies (it ceded Mauritius, St. Lucia and Tobago to Britain IOTL). I know Britain has a phobia of France controlling Belgium, but that's a heck of a good peace deal for them.
