Who is a well-known literary figure who represents the idea of leadership?

Thanks! This is for a research paper where we need a historical figure and a literary figure. My historical figure is FDR, but I can't figure out a good literary representation.Who is a well-known literary figure who represents the idea of leadership?
Hmm..





Harry Potter, sort of, leading everyone against Voldemort/ leader among fellow students


Aragorn from Lord of the Rings


Vetinari from Discworld (though a very authoritarian leadership)
