Battle of Marathon (490 BC): Ten Thousand Greeks Beat Twenty-Five Thousand Persians

On September twenty-sixth, four hundred ninety BC, ten thousand Greek farmers and merchants faced down twenty-five thousand Persian professional warriors on a beach called Marathon. By sunset, the greatest empire on Earth lay shattered in the sand, and Western civilization had bought itself a future measured in millennia.

Think about those numbers for a second. Ten thousand citizen-soldiers against twenty-five thousand battle-hardened Persians. That's a two-point-five-to-one disadvantage. The fate of democracy itself, a radical three-decade-old experiment, hung by a thread so thin it was invisible. Yet by the end of this video, you'll understand how Greek hoplites achieved the impossible.

I'm about to reveal three things that will change how you see ancient warfare forever. First, the tactical gamble that turned numerical weakness into devastating strength. Second, why Persian cavalry, the terror of Asia, never entered the battle. And third, the twenty-six-mile run that saved Athens and created an Olympic legend.
