I certainly won't write your essay for you but I'd recommend doing your paper on Alexander III of Macedon aka Alexander the Great as he was a very influential and interesting figure in Greek history. Although king of ancient Macedonia for less than 13 years, Alexander the Great changed the course of history. One of the world's greatest military generals, he created a vast empire that stretched from Macedonia to Egypt and from Greece to part of India. This allowed for Hellenistic culture to become widespread.
