Spartans
One of the powerful military city-states in ancient Greece was Sparta. This city-state stood out from the others due to its total dedication to rigorous military training. The Spartans used phalanx warfare, like other Greek city-states, to confront the adversary in combat. However, due to their rigorous training regimen, the Spartan phalanx was regarded as one of the best in combat.
Warriors from Sparta were undoubtedly well-trained soldiers. However, in the ancient world, Sparta was renowned just as much for its government, educational system, philosophical culture, economic independence, diplomacy, music, and dancing as it was for its illustrious hoplites. Sparta in antiquity was much more intricate and varied. While they've also been referred to be warrior philosophers, Plutarch asserted that "devotion to the mind is more distinctive of Sparta than love of physical exercise."
