Time to make some moves, as there's a crowd in the political/military leader categories.
First,
HeroQuest moves Genghis Khan to Eastern category (Mongol generals were so important in creating the Mongol tactics and strategy that it's hard to know what exactly was his contribution as a military leader anyway).
Second,
HeroQuest picks Napoleon I of France, better known as
Napoleon Bonaparte (1769 – 1821) in the
Military Leader category.
He is one of the few "total" military leaders. He personally handled both grand and operational strategies as well as the politics, economics and logistics, creating smaller or larger revolutions in all parts of warfare (although often making good use of already existing ideas).
I might expand on this a little later. But propably Napoleons most lasting, important and positive legacies, one of which he was reportedly most proud of, is
one of the most influential documents in history.
Napoleon was instrumental in coming up with and putting to effect the
first succesful codification of law. But of course he did not actually write it. He found a good lawyer to do it.
Third: In the
Innovator/Humanitarian category,
HeroQuest picks
Jean Jacques Régis de Cambacérès (1753–1824),
the main author of the Napoleonic Code.
If you don't know what that is, you should read about it, since it's
"one of the few documents which have influenced the whole world."[1]

He was a pretty moderate man, mostly known for his legal work (and his homosexuality), so for example reading through his Wikipedia article doesn't take long. I think these days we could use a little of this kind of ideological approach to law: understandable and for the general good, made by professionals. There can be upsides to dictatorships.
