Aristotle taught Alexander the Great rhetoric, literature and philosophy. Alexander's father King Philip II invited Aristotle to become his 13-year-old son's personal tutor around 338 B.C.
Aristotle tutored Alexander for only three years before King Phillip II died. Alexander quickly ascended the throne and began his legendary conquest of neighboring lands, but he and Aristotle continued to exchange letters and books. Aristotle is credited with introducing Alexander to Homer's "The Iliad" as well as Greek arts and culture. This later influenced how he treated the cultures of those he conquered. Aristotle also used in his own book "The Art of Rhetoric" to teach Alexander the power of logic and persuasion, both of which made him a charismatic leader and successful strategist.
