Outnumbered Greeks save the beginning of Western Democracy from the spread of Asian tyranny.
The Battle of Marathon is seen as a pivotal moment in European history – the victory of early Greek democracy over the tyranny of Persia. Marathon was a turning point 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 have begun at Marathon. The following two hundred years saw the rise of the Classical Greek civilization which has had enduring influence in Western society.
Though they were outnumbered, the Greeks, mostly Athenians, defeated the Persians because the Athenians and their allies chose a location for the battle, with marshes and mountainous terrain that prevented the Persian cavalry from joining the Persian infantry. Miltiades, the Athenian general, reinforced his flanks, luring the Persians’ best fighters into his center. The inward wheeling flanks enveloped the Persians, routing them. The Persian army broke in panic towards their ships, and large numbers were slaughtered.
The Persian forces, numbering 20,000 soldiers, were sent by King Darius I as a retaliation for the Greeks’ support for the Ionians, who had revolted against the Persians. The defeat at Marathon marked the end of the first Persian invasion of Greece, and the Persian force retreated to Asia. Darius then began raising a huge new army with which he meant to completely subjugate Greece; however, in 486 BC, his Egyptian subjects revolted, indefinitely postponing any Greek expedition. After Darius died, his son Xerxes I restarted the preparations for a second invasion of Greece, which finally began in 480 BC. This invasion would also fail after the heroic defense at Thermopylae by Leonidas’ Spartans and the combined Greek naval victory at Salamis.
