Why was it necessary for the Spartans to always be prepared for conflict?

The Spartans prioritized constant preparedness for conflict due to their militaristic society and the ongoing threat from neighboring city-states, particularly Athens and the helot population they subjugated. Their rigorous training and discipline, exemplified through the agoge system, ensured that every citizen was a skilled warrior ready to defend their territory and maintain control over the helots. Additionally, being perpetually ready for battle helped uphold their societal values and instilled a sense of unity and purpose among Spartan citizens. This relentless focus on military readiness was crucial for their survival and dominance in the ancient Greek world.
