In 416 BCE Athens demanded Melos submit and pay; the island refused. “The strong do what they can and the weak suffer what they must,” the envoys said [2]. After siege, the men were executed and the women and children enslaved. Realpolitik spoke—and killed.

What Happened

Melos sat small and proud in the Cyclades, neutral through the war and close enough to Sparta to hope for rescue. Athens sent envoys and then soldiers. Its demand was simple: join the League and pay tribute. The Melians appealed to justice and the gods. The Athenians replied with arithmetic [2].

Thucydides sets their exchange as a drama: private, austere, and unforgettable. “Right,” said the Athenians, “is only in question between equals in power, while the strong do what they can and the weak suffer what they must” [2]. The line stripped empire of euphemism. Safety lay not in fairness but in fear and calculation.

The siege followed when words failed. Athenian troops walled the city in, their spades biting the island’s pale soil; engines thumped; arrows hissed over the walls. Inside, the Melians counted their grain and prayed for a Spartan sail on the horizon. None came. In time, Melos fell [2].

Athens did what Cleon had urged at Mytilene and what Diodotus had argued against. The men were executed; the women and children enslaved. The island was repopulated. The blue of the Aegean glittered, indifferent, as the empire enacted its logic of terror. The Tribute Lists would add Melos’ name—or at least its property—to the revenue stream.

News raced through the Cyclades. On Delos, pilgrims muttered. On Thera and Paros, magistrates recalculated the odds of resistance. In the Piraeus, some praised strength; others shivered at hubris. The same city that had spun procedure and ritual into compliance now announced that, where persuasion failed, the sword would finish the syllogism [2].

The Melian Dialogue endures because it sounds like a confession and a warning. It was also a policy choice—one that made later pleas for mercy ring hollow in allied ears. The bronze shine on Athena’s shield did not blind all who looked; some saw the blood it reflected.

Why This Matters

Melos distilled imperial realpolitik into a sentence and an atrocity. The Athenian envoys’ maxim—power over right—became the moral emblem of the empire, and the slaughter made it literal [2].

As war-debate-and-decision, Melos shows Athens choosing deterrent terror over profitable restraint. The decision contradicted Diodotus’ logic at Mytilene and undermined claims that Athens preferred stability to vengeance. It taught neutrals and allies that Athens would enslave as well as assess [17][2].

Practically, the island’s destruction added a minor asset and a major stain. The policy’s reputational cost mattered when Athens later needed courage and cash after Sicily; cities judge tyrants as well as benefactors. The envoys’ words kept echoing—in Athenian ears when they begged for support, and in Spartan ears when they promised revenge [2].

For historians, Melos is a text as much as a siege. It frames enduring debates about power and ethics, and it pins the Athenian empire to a line whose clarity still cuts [2].
