Why was Sparta in ancient Greece considered selfish?

Answer 1

Sparta was often considered selfish due to its focus on militarism and the welfare of its own state over broader Greek unity. The Spartans prioritized their own interests and the rigid maintenance of their social order, often at the expense of alliances with other city-states. Their reluctance to engage in cooperative ventures, such as the Delian League, and their harsh treatment of helots (subjugated populations) further contributed to the perception of selfishness. This insular mentality ultimately isolated Sparta from the rest of the Greek world.
