Latest / Ancient Greece: Philosophy, Democracy, and Endless War — Fexingo History / The Spartan Double Kings and the Oracle's Shadow
Transcript
- Lucas: If you’ve been stepping into history with us episode by episode, you know we usually focus on Athens — the democracy, the navy, the philosophers. But for a long time, the real heavyweight in Greece wasn’t the city with the white columns; it was Sparta, or Lacedaemon, as they called their land. Lucas: We’ve talked about their soldiers, their taxes, and even their courtesans, but we haven’t really looked at the men who sat on the two thrones. Sparta didn’t have one king; it had two, from two different families, ruling simultaneously. It sounds like a recipe for disaster, but for centuries, it was the engine of their power. Luna: Two kings at once? How did they not kill each other over every little decision? Lucas: It wasn’t pretty, and it rarely worked smoothly. The system relied on the Agiad and the Eurypontid dynasties checking each other’s ambitions. One king might command the army in the field while the other stayed home to deal with the Council of Elders, but when both were young, aggressive, and standing next to each other, friction was inevitable. Lucas: Let’s zoom in on the early fourth century BCE, right after the Peloponnesian War ended. Sparta was the undisputed master of Greece, but that victory created more problems than it solved. The two kings on the throne were Archidamus III of the Eurypontid line and Agesilaus II of the Agiad line. Both were older men by then, seasoned by decades of conflict, but they had very different visions for what Sparta should do next. Luna: And this is around the time the rest of Greece started getting annoyed with them, right? Lucas: Exactly. By 395 BCE, Thebes, Corinth, and Argos had formed a coalition against Sparta, sparking what historians call the Corinthian War. The Greeks were tired of Spartan bullying, and suddenly, Sparta found itself fighting almost everyone at once. This is where the dynamic between Archidamus and Agesilaus becomes critical because their disagreement over strategy nearly split the state in two. Lucas: Agesilaus was the senior king, and he had just led a massive expedition into Asia Minor, trying to stir up trouble against the Persian Empire. He was winning battles and collecting tribute, which was exactly what a Spartan king wanted to do. But back in Greece, the war was going badly. The Spartans needed him home to defend the Peloponnese from the invading coalition forces. Luna: So he had to choose between personal glory and national defense? Lucas: He had no choice, but the recall was messy. The Ephors, the five elected officials who oversaw the kings, sent the order. But here is the twist: Archidamus III, the junior king, actually encouraged Agesilaus to stay. Archidamus believed that if Agesilaus remained in Asia, he could secure Persian money for Sparta without having to fight the expensive wars at home. Lucas: It was a bold political maneuver. Archidamus thought he could manage the crisis in Greece alone while his rival enriched the state from abroad. But Agesilaus, knowing the political winds back home, ignored Archidamus’s advice and marched his army home immediately. He knew that if he stayed, the Ephors would likely use the delay as an excuse to strip him of his command or charge him with treason. Luna: That must have been incredibly awkward for them to see each other again after years apart. Lucas: You can imagine the tension. When Agesilaus returned, he brought back a huge amount of silver and a reputation that overshadowed Archidamus. In Sparta, military success was currency, and Agesilaus had printed a lot of it. This shifted the balance of power. The Ephors, who usually balanced the kings, now leaned heavily toward Agesilaus because he delivered results. Lucas: This rivalry played out in the shadow of the Oracle at Delphi. The Spartans took their religious directives seriously. Before major campaigns, they would send envoys to consult Apollo. And in this period, the Pythia, the priestess, seemed to favor Agesilaus. She gave him prophecies that framed his campaigns as divinely sanctioned, which made it harder for Archidamus to argue against his strategies in the assembly. Luna: So the gods were basically taking sides in their sibling rivalry? Lucas: In a way, yes. Or rather, the interpretation of the gods was being manipulated. The Spartans believed that military failure was a sign of divine displeasure. So when Agesilaus won, it proved Apollo was with him. When Archidamus suffered setbacks, it suggested he had fallen out of favor. It was a self-fulfilling prophecy that cemented Agesilaus’s dominance. Lucas: But let’s talk about the actual fighting. The Corinthian War dragged on for five years. Archidamus tried to take the offensive in Arcadia, leading a campaign to subdue the local tribes who had joined the anti-Spartan alliance. He was cautious, methodical, preferring to starve cities into submission rather than risk a pitched battle. Luna: Which sounds like the traditional Spartan way, but maybe too slow for the times? Lucas: It was too slow for everyone else. The allies were gaining confidence. Meanwhile, Agesilaus was dealing with the naval threat and the diplomatic fallout. The two kings were essentially running parallel wars that didn’t support each other. Archidamus was bogged down in the mountains, while Agesilaus was navigating the complex politics of the Aegean. There was no unified command. Lucas: This lack of coordination allowed the Persians to step in. They had initially funded Sparta to defeat Athens, but now they realized a strong Sparta was bad for business in Asia. So the Great King switched sides, funding the coalition of Greeks to keep Sparta weak. This financial leverage was devastating for Spartan morale. Luna: I remember hearing about the Satrapal Gold that changed everything. Lucas: Yes, the gold of the Persian satraps flowed into the coffers of Athens and Thebes, allowing them to rebuild their fleets. Without money, Sparta couldn’t pay its rowers or maintain its alliances. The war turned into a stalemate that exhausted everyone. Eventually, the Peace of Antalcidas was imposed by the Persians in 387 BCE, forcing Sparta to give up its Asian territories but confirming its dominance over mainland Greece. Lucas: For Agesilaus, this was a bitter pill. He had spent years trying to liberate the Greek cities in Asia, only to be told by his own king’s enemies to stop. He returned to Greece not as a conqueror, but as a guardian of a status quo that was already crumbling. Archidamus, meanwhile, continued to serve as a capable general, but he never matched his rival’s fame. Luna: Did they ever reconcile, or was there always that underlying resentment? Lucas: They served together loyally in many ways, bound by duty and family tradition. But the historical record, particularly from Xenophon, shows that the respect was strained. Xenophon, who was actually friends with Agesilaus, paints him as the ideal king—courageous, pious, and generous. Archidamus gets a fairer treatment, but he is often cast in the role of the cautious administrator rather than the heroic commander. Lucas: This period also highlights the growing power of the Ephors. As the kings became more focused on external campaigns and personal prestige, the Ephors stepped in to manage the domestic economy and the helot population. They began to dictate foreign policy more directly, using the kings as figureheads when it suited them. Luna: So the kings were losing control of their own state? Lucas: Precisely. The dual monarchy was designed to prevent tyranny, but it also created gridlock. When the kings disagreed, the Ephors often chose the path of least resistance, which usually meant limiting both kings’ powers. This weakening of the royal authority would come back to haunt Sparta later. When the Thebans rose under Epaminondas, Sparta needed a unified, decisive leadership to counter them. Lucas: Instead, they had two old men who had already defined their legacies in a previous era. Archidamus died in 360 BCE, still serving as a general, but he never commanded the main army again. Agesilaus lived until 360 BCE as well, outliving his rival by mere months, but his final years were marked by failed attempts to restore Spartan influence in the face of Theban aggression. Luna: It’s tragic to think their rivalry contributed to the end of their city’s greatness. Lucas: It wasn’t just their rivalry, though. It was the structural flaw of a system that couldn’t adapt. The dual kingship worked when Sparta was expanding and fighting clear-cut wars against Persia or Athens. But in the complex, multi-polar world of the mid-fourth century, it became a liability. They needed a single voice, and they had two competing ones. Lucas: The Battle of Leuctra in 371 BCE, where Epaminondas crushed the Spartan army, was the final nail in the coffin. By then, Agesilaus was gone, and Archidamus’s son, Archidamus IV, was king. But the damage was done. The myth of Spartan invincibility was shattered, and the delicate balance of the dual monarchy could no longer hold the state together. Luna: So the oracle couldn't save them from their own political structure. Lucas: No, it couldn’t. The gods may have favored Agesilaus in the short term, but they couldn’t fix the long-term institutional decay. Sparta remained a respected military power for a while, but it never regained its hegemony. The experiment of the dual kingship, which had sustained them for five hundred years, finally ran out of time. Lucas: It makes you wonder how much of ancient history is shaped by these small, human frictions between powerful individuals. If Archidamus and Agesilaus had been able to unite their strategies, perhaps the outcome of the Corinthian War would have been different. Perhaps Thebes would never have risen. But history rarely gives us second chances for what-if scenarios. Luna: It’s a reminder that even the strongest systems have weak points. Lucas: Absolutely. And those weak points are often human. Whether it’s pride, jealousy, or simply different interpretations of divine will, the people behind the titles drive the events we study. Sparta fell not because it lacked soldiers, but because it lacked unity at the top. Lucas: Before we dive deeper into the aftermath of Leuctra and how Theban tactics changed warfare forever, I want to pause for a moment. These conversations about the past are made possible by listeners like you. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. It helps us keep the research deep and the stories free. Luna: Yeah, it really does make a difference in keeping the quality high. Lucas: Thanks for that. Now, let’s get back to the battlefield. After Leuctra, the world of Greek warfare changed overnight. The hoplite phalanx, which Sparta had perfected, was exposed as vulnerable to new tactical innovations. We need to look at how Epaminondas used density and depth to break the Spartan line, and how this shift affected the role of the individual soldier versus the collective formation. Luna: I’m ready to hear how they broke the unbreakable line. Lucas: It starts with the concept of the oblique order, where Thebes concentrated its strength on one flank to overwhelm the enemy’s weakest point. It was a radical departure from the symmetrical engagements of the past. Let’s trace how this tactical revolution rippled through the rest of Greece, changing not just how armies fought, but how citizens viewed their duty to the state.
