Depends on what you mean by "important," if you mean what world leaders have had the greatest impact, or the most influence, then you could look at leaders like Alexander the Great, Napoleon, Ghangas Khan, Ramses, Nebuchadnezzar, Wiston Churchill, Adolf Hitler, of course these are all political leaders.
