Athens stops an empire at Marathon
What happened
A Persian invasion force sent by King Darius I landed at Marathon, northeast of Athens, intending to punish the city for supporting a failed Ionian revolt against Persian rule. Heavily outnumbered, roughly 10,000 Athenian and Plataean hoplites under the general Miltiades charged the Persian line directly, deliberately weakening their own center so both flanks could swing inward and trap the Persian army once it broke through. By the battle's end, a Greek tradition recorded 6,400 Persian dead against just 192 Athenians, a ratio ancient and modern historians alike treat as exaggerated on the Greek side, though the scale of the Athenian victory itself is not in serious doubt. Afterward, a long-distance runner named Pheidippides is said to have covered 240 kilometers to Sparta before the battle seeking reinforcements, a real feat later confused, by writers working centuries afterward, with a separate legend of a shorter run from Marathon to Athens announcing victory.
Why it matters
Marathon was the first time Greek hoplites had beaten a Persian army in open battle, proof to the rest of Greece that the vast Achaemenid Empire could actually be resisted rather than simply submitted to. It bought Athens a decade before Xerxes returned with a far larger invasion, time Athens used to build the fleet that would decide the war at Salamis instead.
How we know
The battle is described in detail by Herodotus, writing several decades later, while the Athenian burial mound at Marathon, still visible on the plain today, physically confirms that the dead were buried at the battlefield itself rather than returned to the city, an honor usually reserved for a uniquely important victory.
