Brennus Dux gallorum some additional reading for you to learn about the Macedonian history

"Aristotle was born of a well-to-do family in the Macedonian town of Stagira in 384 BCE. His father, Nicomachus, was a physician who died when Aristotle was young. In 367, when Aristotle was seventeen, his uncle, Proxenus, sent him to Athens to study at Plato’s Academy. There he remained, first as a pupil, later as an associate, for the next twenty years.

When Plato died in 347, the Academy came under the control of his nephew Speusippus, who favored mathematical aspects of Platonism that Aristotle, who was more interested in biology, found uncongenial. Perhaps for this reason – but more likely because of growing anti-Macedonian sentiment in Athens – Aristotle decided to leave."
