Sparta was the ancient Greek city-state known for its military culture and rigorous training of its citizens. Unlike Athens, which emphasized arts and philosophy, Sparta's society was predominantly focused on discipline, strength, and military prowess. The Spartan education system, known as the "agoge," instilled these values from a young age, preparing males for service in the Spartan army. Their formidable military reputation was characterized by the famous Spartan warriors, particularly during battles such as Thermopylae. Sparta’s unique social structure and emphasis on collective identity set it apart from other Greek city-states.
