Location
Cause → Event → Consequence
Megara, situated between central Greece and the Peloponnese and possessing two strategically valuable harbors, was an ally of Sparta. Athens sought to exploit tensions within the city and capture this key position, threatening Spartan supply lines and regional influence during the Peloponnesian War.
Athenian forces attacked Megara in 424 BC and initially achieved success against the Peloponnesian garrison. However, Spartan general Brasidas arrived quickly with reinforcing troops, halting the Athenian advance and creating a military stalemate around the city.
The intervention of Brasidas allowed the oligarchic faction within Megara to gain the upper hand internally. Athenian forces subsequently withdrew without securing the city, leaving Megara firmly within the Spartan alliance and its strategic harbors out of Athenian control.
