- Lucas: So we've talked a lot about Persian military power — the sieges, the Immortals, the great battles. But today I want to look at a moment when Persia won without fighting a single battle. I'm talking about the Peace of Antalcidas, also called the King's Peace, in 387 BCE. Luna: Wait, Persia dictated peace terms to the Greek city-states? Lucas: Exactly. And not just any terms — they forced Athens, Sparta, and Thebes to accept a treaty that handed over the Greek cities of Ionia to Persia. It was a diplomatic masterstroke by the Achaemenid king Artaxerxes II and his satrap Tiribazus. And here's the thing: a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what lets us dig into these deep cuts — ad-free, no sponsors, just the history. So if you've been enjoying these conversations, that's where you can help keep them going. Luna: Yeah, it's a small group that makes this possible. And honestly, it's because of them we can spend an entire episode on a treaty that most people have never heard of. Lucas: Right. So the background: after the Peloponnesian War, Sparta dominated Greece, but they were brutal about it. By 395 BCE, Athens, Thebes, Corinth, and Argos had formed a coalition against Sparta — that's the Corinthian War. And both sides went looking for Persian money. Luna: Because Persia had been funding Greek wars for decades by then. Lucas: Exactly. The Persians had learned that it was cheaper to hire Greek mercenaries and bribe politicians than to send armies across the Aegean. So at first, the Persians backed the anti-Spartan coalition. They even put a Greek admiral named Conon in charge of a Persian fleet, and he crushed the Spartan navy at the Battle of Cnidus in 394 BCE. Luna: That must have been humiliating for Sparta. Lucas: It was. But then the Persians started to worry that Athens was getting too strong again. The Athenian general Conon used Persian money to rebuild the Long Walls and the Athenian fleet. And Artaxerxes II's court shifted strategy. They decided that a weak but grateful Sparta was a better counterweight than a resurgent Athens. Lucas: Enter Antalcidas, a Spartan diplomat. He went straight to the Persian satrap Tiribazus in Sardis and offered a deal: Sparta would abandon the Greek cities of Ionia to Persia if Persia stopped funding the anti-Spartan coalition. Tiribazus liked the offer, but he needed the king's approval. Luna: So Antalcidas actually went to the Persian court? Lucas: He did. He traveled to Susa and negotiated directly with Artaxerxes II. The Greek historian Xenophon tells us that Antalcidas argued that Sparta was willing to let Persia have Ionia and the islands — Cyprus and Clazomenae specifically — in exchange for peace. And Artaxerxes agreed. Luna: That's a huge concession from Sparta. They'd been fighting to 'free the Greeks of Asia' for decades. Lucas: Exactly. It was a complete reversal. The Spartans, who had fought the Persians at Thermopylae and Plataea, now handed over their fellow Greeks to secure their own dominance. And in 387 BCE, Artaxerxes issued an edict: all Greek cities in Asia were to belong to the King, and all other Greek cities were to be autonomous — except Lemnos, Imbros, and Scyros, which stayed Athenian. Lucas: The autonomy clause was a knife. It meant Sparta could break up any alliance it wanted — including the Boeotian League led by Thebes. And if any city refused the terms, the King threatened to make war on them, by sea and by land, with those who accepted the peace. Luna: So the Persians essentially became the enforcers of Greek autonomy. Lucas: Exactly. It was a brilliant use of soft power. Persia didn't have to lift a finger. They just said, 'This is the King's Peace. Accept it or face us and our Spartan allies.' And the Greek cities had no choice. The Corinthian War ended, and Sparta became the King's policeman in Greece. Lucas: But here's the irony: the peace only lasted about a decade. Sparta used it to bully its neighbors, especially Thebes. They occupied the Theban acropolis, the Cadmea, in 382 BCE. That eventually backfired when Thebes rebelled under Epaminondas and shattered Spartan power at Leuctra in 371 BCE. Luna: So the King's Peace actually set the stage for Thebes' rise. Lucas: Exactly. And it also showed that the Achaemenid Empire had learned to play the Greek game better than the Greeks themselves. They used diplomacy, bribery, and divide and rule to keep Greece fractured. The Peace of Antalcidas was the high point of Persian interference in Greek affairs. Lucas: One more thing: the Athenian orator Andocides gave a speech in favor of accepting the peace. He argued that Athens was exhausted and couldn't fight both Sparta and Persia. The speech survives, and it gives us a window into how the Athenians justified the humiliation. Luna: Did anyone in Greece speak out against the treaty? Lucas: Yes, but it was risky. The Thebans initially refused to accept the autonomy clause because it dissolved their Boeotian League. But when Sparta and Persia threatened war, they caved. And the Corinthians, who had suffered terribly in the war, were just relieved to have peace. So the treaty held — for a while. Lucas: What's striking is that the Peace of Antalcidas is often overlooked in popular history. Everyone remembers the Persian Wars, the battles of Marathon and Salamis. But this treaty was arguably more consequential — it redrew the map of the Aegean and confirmed Persian control of Ionia for another fifty years, until Alexander. Luna: And it shows that the Persians were just as skilled at diplomacy as they were at warfare. Lucas: Absolutely. The Achaemenid Empire wasn't just about armies and satraps. They had a sophisticated foreign policy that exploited Greek divisions. The Peace of Antalcidas is a perfect example of how they used the 'King's Peace' as a tool of imperial control. Luna: It's almost like a blueprint for later empires — divide and conquer through treaties. Lucas: Exactly. And it worked until the Greeks finally united — under Philip of Macedon. But that's another story. For now, the Peace of Antalcidas stands as a testament to Persian strategic thinking. They didn't need to conquer Greece; they just needed to keep it weak.
