Latest / Marcus Aurelius: Rome's Philosopher King — Fexingo History / The Stoic Emperor's Dream of Lost Provinces
Transcript
- Lucas: So we've spent a lot of episodes on Marcus Aurelius fighting along the Danube, and you might think we've covered the Marcomannic Wars pretty thoroughly. But there's a whole dimension we haven't touched: his plan to actually annex the lands across the river, to turn Marcomannia and Sarmatia into Roman provinces. Luna: Wait, he wanted to expand the empire that far? I thought he was mostly defending. Lucas: That's the common image, and it's true for the early phase. But by the late 170s, after years of punitive campaigns, Marcus was seriously considering permanent conquest. Cassius Dio tells us he had a scheme to make Marcomannia and Sarmatia new provinces, and he even had administrators lined up. Lucas: The sources are a bit tricky. Dio, writing in Greek a few decades later, says Marcus 'wished to reduce Marcomannia and Sarmatia to subjection.' The Historia Augusta, that notoriously unreliable biography collection, claims he would have succeeded if he'd lived longer. But we have to be careful with both. Luna: So it's a real plan, but the details are murky. Lucas: Exactly. Dio might be projecting his own anxieties about barbarian pressure. The Historia Augusta loves a good 'what if' for rhetorical flourish. But the campaign evidence is concrete: Marcus spent years on the frontier, and he didn't just raid—he garrisoned key points and appointed governors. Lucas: Consider this: around 175, he's in Carnuntum, and he's got legions stationed across the Danube in temporary forts. He's also negotiating with tribal leaders, not just for peace but for submission. The Quadi, in particular, were supposed to accept Roman 'protectors' and give up hostages. Luna: So they were being set up as client states? Lucas: Partly, but annexation is a step beyond clientage. It means direct administration, Roman law, taxes, the whole machinery of empire. And there was precedent—Augustus had tried to push the frontier to the Elbe, but Varus lost three legions in the Teutoburg Forest. Marcus knew that risk. Lucas: Yet he pushed forward. The province of Marcomannia would have covered modern Moravia and parts of Austria, and Sarmatia would have taken in the Hungarian plain. That's a huge chunk of Central Europe, and it would have shortened the frontier considerably, making it easier to defend. Luna: But it didn't happen. What went wrong? Lucas: A few things. First, the resistance was fierce. The Quadi broke their oaths, the Iazyges kept raiding, and the terrain was brutal—marshes, forests, and no real cities to anchor Roman administration. And then there was the revolt of Avidius Cassius in the east, which forced Marcus to pull troops away. Lucas: After Cassius was killed, Marcus spent a year out East, and when he came back to the Danube in 178, he was determined to finish the job. He won a big battle against the Quadi and the Marcomanni, and he pushed into Sarmatian territory. But the cost was staggering, and the local population was not exactly welcoming the legions as liberators. Luna: I remember you mentioned the Rain Miracle last time—that was in the middle of this, right? Lucas: Right, the famous lightning and rain miracle of 172, when a legion was saved from thirst. That was during one of the early campaigns, and it became a symbol of divine favor. But by the late 170s, the gods seemed less interested in Roman expansion. Plague was still ravaging the army, and the empire was stretched thin. Lucas: There's also a personal angle: Marcus was a Stoic, and Stoicism teaches that you should act according to nature and reason, not just ambition. Annexing territory might have seemed like a rational way to secure peace, but it also required betraying the principle of not overextending. Some scholars think he was genuinely torn. Luna: Did he write about it? In Meditations, I mean. Lucas: Surprisingly, no. Meditations is intensely personal—it's about his own mind, not policy. He never mentions Marcomannia or Sarmatia by name. But you can read between the lines: he writes about the 'fragility of bodies' and the 'brevity of fame,' which might reflect his doubts about legacy. Lucas: The historian Cassius Dio, who was a senator and knew the imperial bureaucracy, says Marcus was actually planning to 'extend the empire' and that he had even prepared a speech to the Senate about it. But Dio is writing a hundred years later, and he might be mixing up Marcus with later emperors like Septimius Severus. Luna: So we're not even sure he had a formal plan. Lucas: Exactly. But there's circumstantial evidence: inscriptions show new auxiliary units raised specifically for the Danube, and there are remains of Roman-style forts east of the river. Plus, a Roman knight named Pertinax—yes, the future emperor—was given a command in the area, and he later boasted of his 'achievements' against the barbarians. Lucas: Pertinax is a fascinating figure. He was a grammar teacher turned soldier, and he rose through the ranks during the Marcomannic Wars. He commanded auxiliary cohorts, and in 175 he was put in charge of a 'special mission' to secure the Quadi and Marcomanni. He was one of the few Roman officers who actually campaigned in the winter. Luna: A winter campaign? That's brutal. Lucas: It was. The Danube freezes, and both sides used the ice to cross for raids. But a full-scale winter offensive was rare. Pertinax led his men across the frozen river, surprised the enemy, and brought back a lot of plunder. He was so successful that Marcus rewarded him with a seat in the Senate. That's how much the emperor valued aggressive commanders. Lucas: But even with men like Pertinax, the costs were mounting. The Antonine Plague had already killed millions, and the treasury was empty. Marcus had to auction off imperial treasures to fund the war, including some of his wife's silk gowns. He was literally selling the family silver to keep the legions in the field. Luna: That's a powerful image. He's not the detached philosopher king—he's scraping for cash. Lucas: He was both, I think. Stoicism for him was a way to endure, not to avoid action. He once wrote, 'Not to be puffed up by success or broken by failure.' He kept that in mind even as his grand plan slipped away. Lucas: The turning point came in 179. Marcus fell ill—possibly the plague, possibly just exhaustion. He died on March 17, 180, at Vindobona, near modern Vienna. His son Commodus immediately abandoned the offensive and made peace with the tribes, giving up most of the occupied territory. The dream of Marcomannia vanished in a single day. Luna: So Commodus just gave it all back? That seems so wasteful. Lucas: It was, from a strategic view. But Commodus had no interest in his father's plans. He wanted to return to Rome and enjoy himself. The peace he made was actually quite favorable—tribes had to provide troops and grain—but they were no longer subjects. The frontier went back to the Danube, and the provinces were never established. Lucas: And here's something that makes you wonder: if Marcus had lived another five years, would we be speaking a Romance language in Prague? It's a classic counterfactual. But the deeper question is whether Rome could have held those provinces. The costs were enormous, and the tribes were never fully pacified—they revolted again in the third century. Luna: So maybe it wasn't a missed opportunity, but a realistic limit. Lucas: That's what many modern historians think. Rome's power had its limits, and Marcus knew that better than most. He writes in Meditations about the 'empire of the soul' being the only true possession. Maybe he realized that adding a province was less important than keeping his own integrity intact. Lucas: This brings up something we did earlier about the equestrian statue on the Capitoline. That statue shows him on horseback, but with his hand extended in a gesture of clemency, not conquest. The visual message is that true power is about mercy, not expansion. That's Stoic, and it's also a political statement. Luna: Do you think he saw annexation as a mercy too? Like, bringing civilization to the barbarians? Lucas: That's a thorny question. Roman ideology often framed conquest as a gift of civilization, but Marcus was too thoughtful to believe that uncritically. He knew the tribes had their own societies, and he respected their courage. He even tried to integrate them into the Roman army, forming auxiliary units from the Quadi and Marcomanni. Lucas: In the end, the plan failed because of timing, resources, and perhaps a lack of will. But it left an interesting legacy: the name 'Marcomannia' appears on some coins minted during his reign, and later emperors like Diocletian and Constantine revived the idea. They never succeeded either. Luna: It's like a ghost province, always on the edge of becoming real. Lucas: That's a lovely way to put it. A ghost province. And that's probably how Marcus himself might have seen it—something that existed in his mind, a possibility that never materialized. Stoics often talk about the 'inner citadel,' and maybe his true province was that inner space of reason and virtue. Lucas: We've been talking about Marcus's imperial ambitions, and it strikes me that this is a show that tries to understand him as a person, not just an emperor. If you're enjoying these conversations, you might want to help keep them going. We deliberately keep this podcast free of ads, and listener support is what makes that possible. If you're inclined, you can find us at buy me a coffee dot com slash fexingo. Luna: Yeah, it's a nice way to show appreciation. Every little bit helps us keep digging into these stories. Lucas: And we're not going to belabor it. Back to the ghost province—there's a poignant detail from the Historia Augusta that Marcus, on his deathbed, is said to have told Commodus to 'continue the war' and not make peace. But Dio suggests the opposite, that he was weary and wanted peace. The sources conflict, and we'll never know what he truly wanted. Luna: So even his last wish is ambiguous. Lucas: Exactly. And that ambiguity is what makes him so compelling. He was a philosopher who had to act, and an emperor who doubted himself. The ghost province of Marcomannia is a perfect symbol of that tension—a dream that was never realized, but that still speaks to us about the limits of power and the frailty of human plans. Lucas: And that's where we'll leave it for today. Next time, we might explore what happened to the soldiers who fought in those wars, or the fate of the tribes who were caught between Rome and their own leaders. There's always more to uncover.
