The Ionian Revolt, and associated revolts in Aeolis, Doris, Cyprus and Caria, were military rebellions by several Greek regions of Asia Minor against Persian rule, lasting from 499 BC to 493 BC. At the heart of the rebellion was the dissatisfaction of the Greek cities of Asia Minor with the tyrants appointed by Persia to rule them, along with the individual actions of two Milesian tyrants, Histiaeus and Aristagoras. The cities of Ionia had been conquered by Persia around 540 BC, and thereafter were ruled by native tyrants, nominated by the Persian satrap in Sardis. In 499 BC, the tyrant of Miletus, Aristagoras, launched a joint expedition with the Persian satrap Artaphernes to conquer Naxos, in an attempt to bolster his position. The mission was a debacle, and sensing his imminent removal as tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king Darius the Great.

The Battle of Lechaeum was an Athenian victory in the Corinthian War. In the battle, the Athenian general Iphicrates took advantage of the fact that a Spartan hoplite regiment operating near Corinth was moving in the open without the protection of any missile throwing troops. He decided to ambush it with his force of javelin throwers, or peltasts. By launching repeated hit-and-run attacks against the Spartan formation, Iphicrates and his men were able to wear the Spartans down, eventually routing them and killing just under half. This marked one of the first occasions in Greek military history on which a force of peltasts had defeated a force of hoplites.

The battle was to determine which of the two alliances would have hegemony over Greece. However, the death of Epaminondas and his intended successors coupled with the impact on the Spartans of yet another defeat weakened both alliances, and paved the way for Macedonian conquest led by Philip II of Macedon.

After this defeat, the Thirty Tyrants were forced to flee to Eleusis.

The battle was a decisive Spartan victory, which, coupled with the Battle of Coronea later in the same year, gave Sparta the advantage in the early fighting on the Greek mainland.
