Why were Spartans motivated to become so militaristic?

Spartans were motivated to become highly militaristic primarily due to their social structure, which emphasized discipline, strength, and communal loyalty. The need to control the large populations of enslaved helots and prevent uprisings drove them to prioritize military training and readiness. Additionally, their cultural values celebrated heroism, endurance, and the idea of a warrior society, fostering a sense of identity centered around martial prowess and collective security. This militaristic ethos was further reinforced by their rigorous education system, the Agoge, which instilled these ideals from a young age.
