What This Text Is About¶

Thucydides — Pushkin Museum Thucydides (c. 460–400 BCE), historian of the Peloponnesian War and author of the Melian Dialogue.

In 416 BCE — fifteen years after Pericles delivered his celebrated Funeral Oration praising Athenian justice and openness — Athenian military commanders arrived at the small neutral island of Melos with a stark ultimatum: submit to Athenian rule or be destroyed. The Melians refused. Thucydides records the negotiation between the Athenian envoys and the Melian leaders as a formal dialogue — the most famous political negotiation in ancient literature.

The Athenians make no appeal to justice, rights, or morality. They argue only from power: "The strong do what they can; the weak suffer what they must." The Melians appeal to justice, the gods, hope, and the self-interest of other Greek city-states. The Athenians dismiss every appeal. When the Melians still refuse to submit, Athens besieges the island, kills all the men, and enslaves the women and children.

Thucydides presents this without moral commentary. The reader is left to draw the conclusions.

The Setup — Athens Gives Melos a Choice¶

The Melians are a colony of Lacedaemon that would not submit to the Athenians like the other islanders... The Athenians... sent envoys to negotiate. These the Melians did not bring before the people, but bade them state the object of their mission to the magistrates and the few; upon which the Athenian envoys spoke as follows:

The Core Exchange — Power vs. Justice¶

Athenians. For ourselves, we shall not trouble you with specious pretences—either of how we have a right to our empire because we overthrew the Mede, or are now attacking you because of wrong that you have done us—and make a long speech which would not be believed; and in return we hope that you, instead of thinking to influence us by saying that you did not join the Lacedaemonians, although their colonists, or that you have done us no wrong, will aim at what is feasible, holding in view the real sentiments of us both; since you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must.

Melians. As we think, at any rate, it is expedient—we speak as we are obliged, since you enjoin us to let right alone and talk only of interest—that you should not destroy what is our common protection, the privilege of being allowed in danger to invoke what is fair and right, and even to profit by arguments not strictly valid if they can be got to pass current. And you are as much interested in this as any, as your fall would be a signal for the heaviest vengeance and an example for the world to meditate upon.

Athenians. The end of our empire, if end it should, does not frighten us: a rival empire like Lacedaemon, even if Lacedaemon was our real antagonist, is not so terrible to the vanquished as subjects who by themselves attack and overpower their rulers. This, however, is a risk that we are content to take. We will now proceed to show you that we are come here in the interest of our empire, and that we shall say what we are now going to say, for the preservation of your country; as we would fain exercise that empire over you without trouble, and see you preserved for the good of us both.

Melians. And how, pray, could it turn out as good for us to serve as for you to rule?

Athenians. Because you would have the advantage of submitting before suffering the worst, and we should gain by not destroying you.

Melians. So that you would not consent to our being neutral, friends instead of enemies, but allies of neither side.

Athenians. No; for your hostility cannot so much hurt us as your friendship will be an argument to our subjects of our weakness, and your enmity of our power.

On Hope and Survival¶

Melians. Well then, if you risk so much to retain your empire, and your subjects to get rid of it, it were surely great baseness and cowardice in us who are still free not to try everything that can be tried, before submitting to your yoke.

Athenians. Not if you are well advised, the contest not being an equal one, with honour as the prize and shame as the penalty, but a question of self-preservation and of not resisting those who are far stronger than you are.

Melians. But we know that the fortune of war is sometimes more impartial than the disproportion of numbers might lead one to suppose; to submit is to give ourselves over to despair, while action still preserves for us a hope that we may stand erect.

Athenians. Hope, danger's comforter, may be indulged in by those who have abundant resources, if not without loss at all events without ruin; but its nature is to be extravagant, and those who go so far as to put their all upon the venture see it in its true colours only when they are ruined; but so long as the discovery would enable them to guard against it, it is never found wanting. Let not this be the case with you, who are weak and hang on a single turn of the scale; nor be like the vulgar, who, abandoning such security as human means may still afford, when visible hopes fail them in extremity, turn to invisible, to prophecies and oracles, and other such inventions that delight men with hopes to their destruction.

The Outcome — What Happened to Melos¶

The Melians surrendered at discretion to the Athenians, who put to death all the grown men whom they took, and sold the women and children for slaves, and subsequently sent out five hundred colonists and inhabited the place themselves.

ELA Standards This Connects To¶

R.9 — The dialogue is structured as a formal argument with claim and counterclaim — the Athenians make a case; the Melians respond; the Athenians rebut. Students analyze both sides: Is the Athenian argument logically sound? Is the Melian argument morally compelling but strategically naïve? Which is the better argument — on what terms?
W.4 — The Athenian argument is a masterclass in realpolitik argumentation: strip every claim down to interests and power, refuse all abstractions, and be willing to say what most people won't say in public. Use as a W.4 case study: when does an argument become dishonest by being too honest?
C.6 — The text is structured as a dialogue — literally the format of a Socratic seminar. Use in discussion: take positions, build on each other's arguments, and test whether the Melians had any argument that could have changed the outcome. Best C.6 primary source in the library.
R.2 — Thucydides' decision to record this without moral commentary is itself an interpretive choice. Inference work: Why does Thucydides include this dialogue? Is he endorsing the Athenian argument, condemning it, or simply documenting what power looks like without mythology?

WH.6_12.3 — The Melian Dialogue is the defining ancient document for the relationship between democratic governance and imperial power. Athens was a democracy; it also built an empire. The dialogue forces students to confront the question: Can a democracy be an empire? Is the democracy Pericles praised the same political system that destroyed Melos?
WH.6_12.5 — The dialogue directly precedes the Athenian decision to launch the disastrous Sicilian Expedition (415 BCE) — the military overreach that ultimately ended Athenian dominance. Thucydides appears to use Melos as a moral turning point. Students trace causes and effects: did the logic of the Melian Dialogue lead to Athens' own defeat?
WH.6_12.6 — "The strong do what they can; the weak suffer what they must" is arguably the most quoted sentence in the history of international relations. Students find this logic operating in: the Atlantic Slave Trade, colonial empire, WWII, the Cold War, contemporary geopolitics. The question is whether anything has changed since 416 BCE.

Key Vocabulary¶

Term	Definition
Realpolitik	Political decisions based on practical power rather than ethical or ideological principles — the Athenian position is the ancient origin of this concept
Neutrality	Melos had tried to remain neutral in the war between Athens and Sparta — the Athenians argue neutral parties weaken the appearance of Athenian power
Suzerainty	Dominance by one state over another, where the weaker state maintains internal self-governance but submits to the stronger state's authority
Deterrence	The Athenian argument that they must destroy Melos to signal to other neutral or wavering states what happens to those who resist
Thucydidean trap	A modern political science concept (from this text): the danger when a rising power threatens an established power — both are driven toward conflict by logic neither controls

Key Passages¶

Athenians: ...you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must. — Book V, trans. Crawley

Melians: ...you should not destroy what is our common protection, the privilege of being allowed in danger to invoke what is fair and right, and even to profit by arguments that are not strictly valid...

Athenians: ...the standard of justice depends on the equality of power to compel and that in fact the strong exact what they can and the weak grant what they must. — Book V, trans. Crawley

Melians: But we trust that the gods may grant us fortune as good as yours, since we are just men fighting against unjust...

Athenians: Of the gods we believe, and of men we know, that by a necessary law of their nature they rule wherever they can. This law was not made by us, and we are not the first who have acted upon it... — Book V, trans. Crawley

Why these passages matter: The Athenian argument that "the strong do what they can" is not presented as boasting — it is presented as a description of how the world works, as natural as gravity. The Melians' appeal to justice and the gods is not naive — it is the only argument available to a weak party. Thucydides shows us both arguments working correctly within their own logic, and then shows us what happens anyway.

Read This Alongside: Pericles' Funeral Oration¶

This text should never be read alone. It pairs with the Pericles' Funeral Oration — also from Thucydides, fifteen years earlier.

In the Funeral Oration, Pericles argues that Athens is great because it is just, open, and a model for others. In the Melian Dialogue, Athenian envoys tell a small neutral island: "The strong do what they can; the weak suffer what they must." These are the same state, the same democracy, fifteen years apart.

The central question of both texts together: Was Pericles describing Athens or imagining it? Is the Melian Dialogue the truth that the Funeral Oration was designed to obscure?

The Dialogue's Legacy¶

The phrase "the strong do what they can; the weak suffer what they must" has been quoted in: - Every major international relations textbook since the 19th century - The Nuremberg trials (arguing that "following orders" doesn't excuse atrocity) - The UN founding debates (arguing that a rules-based international order is necessary precisely to prevent Melian logic) - Contemporary discussions of great-power competition

This is the oldest political science text in the reading library that is still directly quoted in current events.

Why This Is Relevant Today?¶

The Athenian argument to the Melians — "the strong do what they can, the weak suffer what they must" — is the argument of every great power that has invaded a smaller country, imposed a trade deal, or threatened sanctions to force compliance. Thucydides records it openly because the Athenians didn't bother with euphemisms. Modern great powers usually wrap the same argument in the language of democracy, security, or rules-based order — which is exactly what Orwell described in "Politics and the English Language" 2,400 years later. The Melian Dialogue is relevant whenever a more powerful country tells a weaker one what it must accept, whenever permanent members of the UN Security Council veto resolutions about their own actions, or whenever international law is described as what the powerful choose to enforce. The Melians argued for neutrality and international norms. The Athenians destroyed them anyway. That outcome matters too — it tells you something about what norms without enforcement actually are.
