Greece a country united by its name, but divided by its ways. Although Sparta and Athens were both Greek cities, their societies were different. Sparta was focused on having a perfect military, whereas Athenian daily life revolved learning and knowledge. When Spartan boys were being trained for an army, Athenian boys were being trained for life.
Sparta was a city-state based on strict military ruling. Lives of Spartans revolved around military. The education given was meant to create Spartans into soldiers. Not only were the Spartans raised to be military-minded, but they were also expected to be a disciplined marching army. The strict rules of the government made it so that every Spartan was to be physically fit. Those rules would be easier to deal with than some of the other laws that were firmly instituted. Such as, when a baby was born, Spartan soldiers came to see if the baby was healthy.
If the baby did not seem to be healthy and strong, then the infant would be taken away and left to die on a hillside. The baby would be left to die, but if the baby was not taken away to die, then the infant would be trained to be slave (or helot). Now, if an infant was found to be perfectly healthy, then the child was assigned a brotherhood or sisterhood. They were usually assigned to the same one as their mother or father.
Schooling in Sparta started at age six or seven. The children were not well fed and the boys were taught to steal food. When they stole food, they could not get caught, for if they were caught, there were great consequences. There was an anecdote that speaks of a boy who stole a fox because he wanted to cook and eat it.
