I'm a fierce advocate
against Napoleon for France. Sincerely, he did some incredible things, but I see him more as a bloody dictator than a ruler we ought to look upon. Do you know that he's responsible for the fact that French are
waaaay more prone to suffer from varicose veins because of him? Varicoses were a reason to be exempted to serve in Napoleonic armies, and so much soldiers died for Napoleon that it completely shift the genetic inheritage of French people. We often talk how Gengis Khan is the father of so much of the population, but Napoleon managed to screw the genes of a whole country.
Moreover, if we ought to have a second leader for France, I'd rather have a republican one rather than another monarchist (even if he's an imperial one). Sure, the Third Republic had her share on the Scramble of Africa, but as much as Victoria, so it's not that bad.
Jules Ferry could be a good one, especially a scientific leader for France, to show his school and education reforms quite fundamental for contemporary France. But, look at the
wonderful sideburns.
But if we want a militaristic leader for France, Louis XIV could work for both the cultural and militaristic aspect. Sure, he ruined the country... But didn't all kings did that? And Louis IX (Saint Louis) could be used as a military/religious leader, if you really want a militaristic leader. But... Please, not Napoléon (except if his ability is what I thought:
make Great Scientists and Great Engineers act as Great Generals too).
