Also because I'm bored --
Xerxes I the Great, Persian King of Kings, 485-465 BC
The way he was portrayed in the movie 300 is very obviously EIE, and I think it's a plausible type for the historical person as well (a hunch in this case).
"I only require that you kneel before me -- because I am kind" (in the movie).
Trajan, Emperor of Rome, 98-117 AD
He's easier to type than you might think -- lots of his letters have survived.
Constantine I the Great, Emperor of Rome 306-337 AD
The guy who made Christianity into the western world's chief religion. Liked to style himself "the 13th apostle".
Jumping a few centuries --
John Kennedy, US president
Ronald Reagan, US president
Valéry Giscard d'Estaing, French president 1974-81
(note that in his tv farewell as president, he made a point of standing up and walking away, live, something he had never done before)
Nelson Mandela , president of South Africa 1994-99, and Muammar al-Gaddafi "Brotherly Leader and Guide of the Revolution" of Libya
