Galadriel. She would be a great and terrible queen. All would love her, and despair.
> People that don't know any history?
For some reason, I find that people who accuse others of not knowing history tend to be the most ignorant of it themselves. History buffs don't seem to be walking around telling other people they "don't know any history". Just an observation.
For an example of a benevolent dictator, look at King Leopold II of Belgium, the Builder King. Loved by his people. Created the Royal Trust, donating a most of his properties to the Belgian nation. Brought culture and prestige to Belgium.
For an example of the atrocities of a malevolent dictator, look at King Leopold II of Belgium. The butcher of the Congo. Unbelievable exploitation and atrocities committed under his rule.
Or look at Ashurbanipal, the last "Great King" of Assyria, who built one of the greatest libraries in history; a collection of human knowledge surpassed in the ancient world only by the Library of Alexandria. And a genocidal maniac who spent months not just pillaging and raping opposing cities long after they had been defeated, but destroying any trace of the people who lived there, salting the land, and seeding the ground with weeds so that it would be impossible to ever re-build.
A wise builder-king with the power and drive to make the nation and world a better place for all its people would absolutely be the best government humanity has been able to achieve so far. Checks and balances are a necessity for a functioning government, but they do bog things down.
My point, of course, is that this is completely counter to human nature, and has (almost?) never been achieved, even in those times that it appears that it has.
