The ruling class, the Spartiates, gave themselves wholly to war. At birth a boy was inspected by the elders, and if he appeared too weakly for future military service, he was taken into the mountains and abandoned. If he was fit, he was taken from his mother at the age of seven to begin rigorous military training. He became a soldier at 20, a citizen at 30, and continued as a soldier until 60. Thus his entire life was spent under rigorous discipline.
