Sparta, known as a formidable land-based power, owed much of its strength to its highly trained soldiers known as hoplites. The Spartan military operated under a strict code of discipline and obedience, demanding its warriors to be tough and self-reliant. Physical fitness and rigorous training held great significance in Spartan society, with a focus on developing strong and capable soldiers. The military structure of Sparta revolved around a dual kingship and a council of elders, which provided a hierarchical organization for their forces.
