361 BCE

The Egyptians under their King Teos and the Spartans under King Agesilaus II, with some Athenian mercenaries under their general Chabrias, set out to attack the Persian King's Phoenician cities. However, they have to return almost at once due to revolts back in Egypt. Subsequently, Agesilaus II quarrels with the Egyptian king and joins a revolt against him. With the Persian empire weakening, revolts occur in many parts of the empire, including Sidon, a prosperous and rich Phoenician city. Plato returns once more to Syracuse to teach the young Syracusan tyrant Dionysius II. He fails to reconcile the tyrant to Dion, who Dionysius II banished in 366 BC. Because of this, Plato is forced to flee Syracuse to save his life.
