Mantinea dismantled under 'autonomy' policy

Autonomy, on paper, promised local freedom. In Arcadia, it meant Spartan bulldozers with bronze tips. Mantinea—an Arcadian city of weight and walls—had long leaned toward coalitions unwelcome in Lacedaemon. Under the King’s Peace, Sparta claimed a right to police coerced unions. In 385, Agesilaus II and his peers resolved to apply the principle where it hurt [3], [4], [10].

Xenophon, sympathetic to Sparta yet candid, narrates the deed. Mantinea’s walls came down. The city was split into its ancestral villages. The soundscape was not of speeches but of picks and sledges: stone cracking, wheelbarrows groaning, orders barked beneath the Arcadian sky. The color that day was the gray of dust coating red cloaks and work-scarred tunics alike [4].

Places frame the wound. In the central Peloponnese, Mantinea had guarded roads between Tegea, Orchomenus, and the routes north to the Corinthian Isthmus. Village-izing it atomized a node in any future Arcadian league. To the west, Megalopolis did not yet exist; to the south, Sparta’s Eurotas plain lay quiet but watchful. The King’s Peace language—“autonomous” poleis—became a crowbar to pry apart inconvenient solidarities [3], [10], [11].

The act rippled. In Phlius and Sicyon, elites weighed whether to appease or resist when harmosts appeared. In Thebes and Argos, men took note: autonomy could be a mask for coercion. The Peloponnesian League’s bilateral ties carried the immediate order; allied contingents stood by if needed. No common treasury was required to pay for this kind of policy—just authority and will [4], [16].

Mantinea’s people returned to fields and hamlets, their market square abandoned to weeds. The silence of civic life interrupted only by the distant clatter of carts was its own kind of sentence. Two decades later, Arcadians would remember and build a federal capital—Megalopolis—under Theban auspices. For now, Sparta won. And lost a little more of the legitimacy it could ill spare [5], [10], [11].
