"The Athenians, as defenders of the Hellenes, in Marathon
destroyed the might of the golden-dressed Medes"
Epigram on the tomb of the Athenians at Marathon

2500 years ago: The Battle of Marathon took place on September 12, 490 BC, during the first Persian invasion of Greece. It was fought between the citizens of Athens, aided by Plataea, and the Persian invasion force.It was the culmination of the first attempt by Persia, under King Darius I, to subjugate Greece. The first Persian invasion was a response to Greek involvement in the Ionian Revolt, when Athens and Eretria had sent a force to support the cities of Ionia in their attempt to overthrow Persian rule. The Athenians and Eretrians had succeeded in capturing and burning Sardis, but were then forced to retreat with heavy losses. In response to this raid, the Persian king Darius swore to have revenge on Athens and Eretria.
Once the Ionian revolt was finally crushed by the Persian victory at the Battle of Lade, Darius began to plan to subjugate Greece. In 490 BC, he sent a naval task force under Datis and Artaphernes across the Aegean, to subjugate the Cyclades, and then to make punitive attacks on Athens and Eretria. Reaching Euboea  in mid-summer after a successful campaign in the Aegean, the Persians proceeded to besiege and capture Eretria. The Persian force then sailed for Attica, landing in the bay near the town of Marathon. The Athenians, joined by a small force from Plataea, marched to Marathon, and succeeded in blocking the two exits from the plain of Marathon. Stalemate ensued for five days, before the Athenians (for reasons that are not completely clear) decided to attack the Persians. Despite the numerical advantage of the Persians, the hoplites  proved devastatingly effective against the more lightly armed Persian infantry, routing the wings before turning in on the centre of the Persian line.The defeat at Marathon marked the end of the first Persian invasion of Greece, and the Persian force retreated to Asia. The defeat at Marathon marked the end of the first Persian invasion of Greece, and the Persian force retreated to Asia. 
The Battle of Marathon was a watershed in the Greco-Persian wars, showing the Greeks that the Persians could be beaten; the eventual Greek triumph in these wars can be seen to begin at Marathon. Since the following two hundred years saw the rise of the Classical Greek  civilization, which has been enduringly influential in western society, the Battle of Marathon is often seen as a pivotal moment in European history. For instance, John Stuart Mill famously suggested that "the Battle of Marathon, even as an event in British history, is more important than the Battle of Hastings".
The Battle of Marathon is perhaps now more famous as the inspiration for the Marathon  race. Although historically inaccurate, the legend of a Greek messenger running to Athens with news of the victory became the inspiration for this athletic event, introduced at the 1896 Athens Olympics, and originally run between Marathon and Athens.
