After 404 BCE, Sparta exported control by stationing harmosts and backing oligarchies from Piraeus to Samos. Boots scraped on citadel steps while city councils shrank to loyal boards. The network built by Lysander turned victory into a system—effective at first, corrosive in time.

What Happened

Victory demanded administrators, not just hoplites. In the months after Athens fell, Spartan commissioners fanned out from the Isthmus to the Hellespont, installing harmosts—military governors with small garrisons—in key harbors and citadels [1]. The creak of new doors on the Acrocorinth answered the ring of keys in the Cadmeia at Thebes, while at Piraeus a Spartan polemarch reviewed the quay at dawn.

The political engineering was simple in design and sharp in execution. Replace broad assemblies with smaller councils; prefer oligarchic boards aligned with Spartan interests; keep a harmost and 100 to 300 men on site as insurance. In Athens, the Thirty ruled; in Samos, in Byzantium, in Lampsacus, similar patterns took hold, often under the patronage of Lysander, whose personal prestige and client network glued these regimes together [1][14]. Bronze helmets at the council door made the point more vividly than decrees did.

Xenophon shows the reach of this architecture. His narrative slips from island to isthmus with the same assumption: Sparta commands; cities comply; dissenters count the cost [1]. At Miletus on the Ionian coast, oligarchs leaned on Spartan favor; at Ephesus, Spartan officers drilled men under an azure sky; in the Peloponnese, nearby Elis felt the weight of an irritated neighbor. The model worked because fear worked.

But every harmost generated his own politics. The scarlet cloak in a city’s citadel meant security for allies and insult for enemies. Local rivalries sharpened under the shield of Spartan authority. Where Lysander’s decarchies found a footing, they could last months or years; where they collided with civic identities—Corinth proud, Thebes prickly—the arrangement bred quiet rage. The sound of armored feet outside an assembly chamber turns debates into rehearsals [14].

The system looked cheaper than constant campaigning. A garrison of 200 could hold what an army of 10,000 had won; a council of ten could pass what a crowd of 5,000 would not. But coercion carries interest. Each insult to autonomy accumulated like dust on the steps of a temple, waiting for a wind strong enough to blow it back into Spartan faces [11][14].

For the moment, Sparta’s supremacy seemed unassailable. Ships carried harmosts to Samos and Chios; messengers traced routes through Corinth and Thebes; a single city—Sparta—spoke commands that a hundred heard. Then, in 395, alliances reshuffled and Persian coin clinked into Greek purses. The system built on garrisons would be tested by a war that began not in Laconia, but at Corinth and Thebes [15][1].

Why This Matters

Harmosts and oligarchic regimes converted Spartan battlefield gains into a continental management system. They delivered obedience with small garrisons, gave Sparta influence over city councils, and bought time by suppressing local opposition at low military cost. This directly extended the hegemony from 404 into the 390s [1][14].

The arrangement embodies the theme of garrisons, oligarchs, and compliance: force-backed institutions substituted for legitimacy. The overt security of bronze and scarlet masked the fragility beneath; each garrison doubled as a provocation. Phoebidas’s later coup in Thebes was the system taken to its amoral extreme—useful in the short term, ruinous in the long [3][14].

Strategically, the net of harmosts made Sparta vulnerable to naval shocks. When a Persian-backed fleet smashed Spartan sea power at Cnidus in 394, the capacity to reinforce or even pay distant garrisons vanished overnight. Control that had seemed entrenched in Samos or Byzantium depended on ships Sparta could no longer protect [15][1].

Historians read these years as a tutorial in how coercive hegemony corrodes itself. Xenophon’s proximity makes clear how natural the regime felt to Spartan eyes—and how galling it appeared to others. The later King’s Peace would codify this dynamic in the language of ‘autonomy,’ with Sparta as enforcer and Persian suzerainty in Asia as the price [1][12][19].
