He studied under the philosopher Socrates and later founded his own school, the Academy, where he continued to teach and write influential philosophical works.

Alexander was first tutored by the strict Leonidas, a relative of his mother, and by Lysimachus of Acarnania. In early childhood Alexander was raised in the manner of noble Macedonian youths, learning to read, play the lyre, ride, fight, and hunt.

When Alexander was 13, Philip began to search for a tutor and considered such academics as Isocrates and Speusippus, the latter offering to resign to take up the post. In the end, Philip chose Aristotle and provided the Temple of the Nymphs at Mieza as a classroom. In return for teaching Alexander, Philip agreed to rebuild Aristotle's hometown of Stageira in central Macedonia near the eastern coast of the peninsula of Chalcidice, which Philip had razed, and to repopulate it by buying and freeing the ex-citizens who were slaves or pardoning those who were in exile. Many new structures were built at this time, including an aqueduct, two shrines to Demeter. and many houses.
