The ancient Greek city-state known for its military prowess was Sparta. Renowned for its disciplined and formidable army, Sparta emphasized a rigorous military education known as the agoge, where male citizens trained from childhood for warfare. Spartan society valued strength, resilience, and loyalty, prioritizing the collective over individual desires. This military focus enabled Sparta to dominate various Greek conflicts, especially during the Peloponnesian War against Athens. While Sparta is often remembered for its rigidity and austere lifestyle, it played a critical role in shaping the power dynamics of ancient Greece.
