The Spartan army was the toughest in the world. Every Spartan man was enlisted, and they were feared around the world. Sparta did away with city walls, believing its men strong enough to make walls useless. It was the only country that Alexander the Great saw and left unconquered—and he never even had the courage to march his men into their land.
Spartan men were warriors because Spartan boys suffered through some absolutely incredible experiences. A child raised in Sparta wasn’t raised by his mother. He was raised by the state, and he was put through an education unlike any other in history.
