Napoleon Bonaparte was the Corsican son of a minor noble who became an emperor. He was at once a man of the enlightenment and a ruthless despot. You might even call him an enlightened despot. He Tolerated different religions, Reformed laws, ruled with Absolute authority, and Patronized the arts (if you consider pillaging national treasures of conquered lands patronage). 

Napoleon was born great, made great by circumstance, both, neither, something we haven't thought up yet... 

Honestly, the "Great Man" debate makes about as much sense to me as the human nature debate. For my money, "both" is the horse I'm backing. Also, that horse doesn't have to be a man in my estimation...but the metaphors are starting to mix and I'm going to stop typing before this description gallops away from me. 

Hee hee.
