The Battle of Marathon, 490 B.C.
The battle of Marathon is one of history's most famous military engagements. It is also one of the earliest recorded battles. Their victory over the Persian invaders gave the fledgling Greek city states confidence in their ability to defend themselves and belief in their continued existence. The battle is therefore considered a defining moment in the development of European culture. In September of 490 BC a Persian armada of 600 ships disgorged an invasion force of approximately 20,000 infantry and cavalry on Greek soil just north of Athens. Their mission was to crush the Greek states in retaliation for their support of their Ionian cousins who had revolted against Persian rule.
