I understand that sources like Plutarch emphasise the uniqueness of Sparta in its educational and social organisation, with them supposedly being geared towards creating a professional class of soldiers. But in practice during the archaic period (8th to early 5th century) did Sparta actually engage in more aggressive wars or warmongering than other Archaic Greek city-states? and do we know whether Spartan society was actually designed to create the perfect soldier class for warfare, or were they concerned with other end goals such as controlling internal conflict or some idea of eugenics and physical health?
