“History is really interesting because it’s about people. And people are interesting. So there are plenty of different ways of doing this, and I think there’s room for everybody.” — Adrian Goldsworthy

The greatest rivalry in antiquity is also uncomfortably relevant to us today. In Athens and Sparta: The Rivalry That Shaped Ancient Greece, the classical scholar Adrian Goldsworthy covers the long fifth century BC, from the Persian Wars that forced Athens and Sparta into alliance, through the Peloponnesian War that set them against each other.

The parallels of the rivalry between Sparta and Athens are uncannily relevant today. Goldsworthy traces the NATO-like structure of the Athenian alliance, with its familiar complaint that the allies weren’t paying enough. He notes that Athens, which outgrew its ability to grow its own food, had to secure its grain supply from the Black Sea — in the same way as closing the Straits of Hormuz has disrupted modern supply chains. And he observes that the Spartans won the Peloponnesian War by getting Persian money — while the Athenians were doing exactly the same thing. Persia, he notes, is always lurking in the background. There would be no “west” without it.

Five Takeaways

• Athens and Sparta: Two Experiments, One Greek Longing: Both city states were driven by the same competitive Greek impulse — the desire to excel, to be the best. But they ran radically different experiments in how to achieve it. Athens: radical democracy, open society, maritime empire, philosophy, drama. Sparta: apartheid military state, in which a tiny Spartan elite was freed from all labour by a vast population of helots, so that they could devote their entire lives to being warriors and citizens. Two models for a polity that still structure political argument today.

• Thucydides: Essential but Embittered: The History of the Peloponnesian War is the essential source — and the problematic one. Thucydides was an Athenian general who failed to save a city from a Spartan-led force and went into exile as a result. He is analytical and apparently balanced in ways that seem modern. But he cannot hide his biases: the demagogue Cleon gets speeches written for him that make him look like a self-interested buffoon. And his silences are as revealing as his words — large events, including an Athenian disaster in Egypt, are mentioned only vaguely. He tells us what he wants to tell.

• The NATO Parallel: They Weren’t Paying Enough: The Delian League — the Athenian alliance that emerged after the Persian Wars — has a structural similarity to NATO that Goldsworthy notes carefully. Athens, like the United States, is the dominant naval power that has mobilised for a great threat and then chosen not to demobilise. The allies, like European NATO members in successive administrations’ complaints, weren’t willing to send ships or men. They’d just send a bit of cash. The Athenian fleet ends up overwhelmingly Athenian. As the threat recedes, the other states increasingly resent the protection they’re receiving from it.

• Persia Is Always There: The Spartans won the Peloponnesian War by securing subsidies from the Persian Empire. The Athenians were doing the same thing. The irony: both sides of the Greek world’s greatest internal conflict ended up funded by the barbarian power they had united to defeat a generation earlier. Goldsworthy draws the modern parallel delicately: America is now fighting a war in Iran, once known as Persia. Europe chose not to join. The question of who Persia is in any given age is always live. Persia, he says, is always there. It always has been.

• Athens as a Theme Park: The Roman Legacy: In the Roman period, Athens and Sparta became what Goldsworthy calls “university cities or, in Sparta’s case, a theme park.” Sparta, having lost any real military or political power, invented a public performance of its old customs — a tourist attraction for Roman visitors who wanted to see the old ways enacted. Athens was a university town for the Roman elite, whose children went there as we might go to Oxford. What we think we know about classical Greece is partly filtered through this late antique nostalgia — a celebration of how great we used to be.
