What happened
Plato, born around 428/427 BCE, gathered a circle of fellow philosophers in Athens that gradually developed into the institution known as the Academy, named for the sacred grove of the hero Academus where it met, just outside the city walls. Scholars place the founding anywhere from 387 to 383 BCE, depending on how they date Plato's return from his first trip to Syracuse, and the school appears to have grown gradually rather than opening on a fixed date. The Academy remained Plato's base for the rest of his life and continued after his death in 347 BCE, surviving as an institution until the Roman general Sulla destroyed its grove and gymnasium in 86 BCE, though thinkers identifying as Platonists carried on in Athens for centuries after that.
Why it matters
The Academy is often treated as the first institution in the Western world organized specifically around sustained philosophical inquiry rather than religious or civic function, and it trained Aristotle, among many others, giving it an outsized role in shaping the following century of Greek thought.
How we know
The Academy's location, general founding period, and eventual destruction under Sulla are documented across multiple ancient sources describing Plato's life and the site's later history, though the exact founding year is not fixed in any single ancient text and remains a matter of scholarly inference.
