In short
In September 490 BC, roughly 10,000 Athenian and Plataean hoplites defeated a much larger Persian invasion force on the plain of Marathon, northeast of Athens. The victory halted Darius I's attempt to conquer Greece and became a defining moment in Western history—proving that a disciplined citizen army could overcome an empire's professional soldiers.

Timeline
How it actually unfolded.
Persian fleet departs Asia Minor
Datis and Artaphernes lead the Persian expeditionary force across the Aegean toward Greece, beginning Darius I's first invasion attempt.
Persian force lands at Marathon
The Persian fleet arrives at the Marathon plain, approximately 40 kilometers northeast of Athens. The invasion force expects to meet minimal organized resistance.
Greek forces mobilize
Athens and Plataea assemble their hoplite armies at Marathon. Miltiades persuades the Athenian generals to engage the larger Persian force rather than wait for siege.
The Battle of Marathon
Greek hoplites, arranged in a phalanx formation, charge the Persian line. The Greek center feigns retreat while stronger flanks encircle the Persian force, breaking their formations and routing the army back to their ships.
Persians withdraw to Asia
Unable to maintain the invasion without reinforcements and facing a recharged Athenian force, the Persian fleet sails for home. Darius I suspends further Greek conquest attempts for a decade.

Impact
What followed.
Marathon demonstrated that organized Greek city-states could stand against the Persian Empire's military might. The psychological and strategic victory bought Athens time to prepare for future invasions and helped establish the polis system as a viable alternative to autocratic rule across the Mediterranean.
