In Sparta, 9,000 Spartan slave owners ruled more than 250,000 slaves, and there were about 30,000 Pyrrhians. Because slaves can't stand long-term inhuman rule, they often run away or rebel. Because the geographical environment of Sparta is easy to defend but difficult to attack, it has long been at odds with its neighbors and is often threatened by military aggression from other countries. Faced with such a harsh reality, the slave owners' ruling class in Sparta had to brutally suppress slave uprisings and riots at home and resist foreign military aggression in order to maintain their own rule.

In Sparta, almost all major affairs are handled and directly managed by the state, and education is no exception. In order to safeguard the national rights and social and political system of Spartans, the ruling class attached great importance to education. "The direct goal pursued by the country is to cultivate Spartans into war land and become powerful, well-trained and future slave owners. All education in Sparta is also subject to this task. " In order to achieve this goal, all Spartans should receive military education and training from an early age to serve national security.

In Sparta, babies born with normal physical development and no diseases or defects are allowed to survive, and their mothers or nannies are responsible for taking care of them until they reach the age of 7. Boys will be sent to national educational institutions to receive military sports training all the year round until 18 years old.

In order to meet the needs of the cruel war in the future, children and teenagers should spend most of their daytime on military sports training, wrestling, fighting games and ball games; They should often participate in the internship activities of killing slaves at night to exercise their courage and practical ability; In order to make future soldiers develop superhuman endurance, educators often make children face all kinds of hardships and endure hunger, thirst, cold and pain in the process of receiving education and training.
