Introduction. Sparta was a warrior society in ancient Greece that reached the height of its power after defeating rival city-state Athens in the Peloponnesian War (431-404 B.C.).
Education in Sparta was completely different. The purpose of education in Sparta was to produce and maintain a powerful army. Sparta boys entered military school when they were about six years old. They learned how to read and write, but those skills were not considered very important except for messages.
