Latest / Nero: Mad Tyrant or Misunderstood Emperor? — Fexingo History / Nero's Danube Dream: The Sarmatian Campaign That Never Was
Transcript
- Lucas: So we've covered a lot of Nero's reign by now — the fire, the Domus Aurea, the Armenian settlement with Tiridates, even his grain fleet. But there's one big thing that never actually happened, yet it loomed large in his plans: a major military campaign on the Danube frontier against the Sarmatians and the Dacians. Luna: Wait, I've never heard of a Nero Danube campaign. Was this an actual plan? Lucas: It was. Throughout the 60s AD, Nero seriously considered launching a northern war that would have rivaled Caesar's conquest of Gaul. He even raised a new legion, the I Italica, specifically for this purpose. The target was the Sarmatian tribes — the Roxolani and the Iazyges — who had been raiding across the Danube into the Roman province of Moesia. Luna: And also the Dacians, right? They were a major threat later under Domitian and Trajan. Lucas: Exactly. The Dacian kingdom under King Scorilo — and later Decebalus — was a growing power. But what's fascinating is that we have a key figure from this period who actually did fight the Sarmatians: Tiberius Plautius Silvanus Aelianus. He was the governor of Moesia around 60 AD, and he conducted a series of campaigns that stabilized the frontier. An inscription from his career — the so-called 'CIL VI 1444' — records that he crossed the Danube with an army, defeated the Roxolani, and resettled over one hundred thousand people from across the river into Roman territory. Luna: One hundred thousand? That's an enormous number. Were they refugees or captives? Lucas: The inscription says they were 'translatis ex ulteriore ripa' — transferred from the farther bank. It's not entirely clear if they were prisoners of war or peaceful migrants, but either way, it was a massive demographic shift. Plautius also brought back hostages from the Sarmatian chiefs and even sent a delegation of Sarmatian nobles to Rome to swear allegiance to Nero. Tacitus mentions him too, in the Histories, describing how he kept the province peaceful. Luna: So Nero had a capable commander already doing the work. Why didn't he go north himself? Lucas: That's the million-sesterce question. Part of it was timing. In 66 AD, the Jewish Revolt broke out, which tied up a huge number of legions. Then in 68, the rebellion of Vindex in Gaul and Galba in Spain triggered Nero's downfall. But there's also evidence that Nero's plans were genuinely ambitious — maybe too ambitious. Suetonius says Nero planned an expedition to the Caspian Gates and even to explore the sources of the Nile. And Pliny the Elder mentions that Nero sent a reconnaissance mission to the Black Sea and the Danube delta to scout a route to India. Luna: A route to India through the Black Sea? That sounds more like fantasy than strategy. Lucas: It does, but the geography isn't completely crazy. The idea was to sail up the Danube, then portage to the Vistula or the Dnieper — ancient sources called them the 'Vistula' and 'Borysthenes' — and then down to the Black Sea again, or even further east. Pliny writes that Nero's explorers reported that the Caspian Sea was connected to the Northern Ocean, which would have opened a trade route to the Far East. Of course, that turned out to be wrong — the Caspian is landlocked — but the sheer ambition is staggering. Luna: So Nero was essentially trying to pull a Caesar, maybe even outdo him. But he ran out of time. Lucas: Exactly. If Nero had managed even a partial success on the Danube — say, a decisive defeat of the Roxolani and the annexation of Dacia — his legacy would be totally different. Instead, the man who actually conquered Dacia was Trajan, fifty years later. And Trajan's column in Rome stands as a monument to what Nero dreamed of. There's a tragic irony there. Luna: It's interesting that so much of Nero's planning survives only in fragments — an inscription here, a line in Pliny there. Do we have any idea what his specific war aims were? Lucas: We can piece it together from a few sources. First, the military buildup: besides the I Italica, Nero also formed a unit of Macedonian phalanx reenactors — yes, he actually revived the phalanx for show. But more practically, he ordered the construction of a fleet on the Danube, the 'classis Moesica', which later became a permanent force. And we know from Tacitus that the governor of Moesia, Plautius, was given extraordinary powers — he had the authority to make peace and war independently. That suggests Nero was serious about a major push. Luna: But wasn't Nero also distracted by his artistic tours? I remember from the Olympic episode that he went to Greece in 67 AD. Lucas: That's another factor. Nero left for Greece in September 66 and didn't return until early 68. While he was there, he 'liberated' the Greek provinces — declared them free from Roman taxation — and performed in every festival. That was his priority. So the Danube campaign was planned but never executed, partly because Nero was busy being an artist. The Jewish revolt also required the transfer of legions from the Danube to Judea, which weakened the frontier. So it was a combination of strategic overstretch, personal distraction, and ultimately political collapse. Luna: What about the Sarmatians themselves? Were they really a credible threat, or was this a case of Roman imperial overreaction? Lucas: The Sarmatians were a real danger. They were nomadic horse archers, similar to the Parthians but with a different culture — they wore scale armor and used long lances, and they had a reputation for ferocity. They had been raiding Moesia for decades. In 69 AD, during the Year of the Four Emperors, the Roxolani actually invaded and destroyed a Roman legion — the III Gallica was ambushed and lost its eagle. So Nero's concern was justified. And the Dacians, under Scorilo, had also made incursions. A campaign to subdue both would have been a massive undertaking. Luna: I keep thinking about that inscription for Plautius Silvanus — it sounds like he accomplished a lot without a full-scale war. Could diplomacy have worked instead? Lucas: That's a great point. Plautius's method seems to have been a combination of force and negotiation. He defeated the Sarmatians in battle, but then he resettled tens of thousands of them as Roman subjects — creating a buffer zone. He also brought Sarmatian kings to Rome to acknowledge Nero's supremacy. That's exactly the same approach Nero used with Tiridates in Armenia: a diplomatic solution backed by military credibility. So maybe Nero's Danube plan was less about conquest and more about a grand diplomatic settlement, like a 'Pax Neroniana' on the northern frontier. Luna: That would fit his image as a peacemaker — the closing of the Temple of Janus, the Armenian settlement. But the sources paint him as a warmonger too. Lucas: The sources are contradictory. Cassius Dio says Nero 'desired to perform some great and brilliant feat' and that he 'planned to make an expedition against the peoples beyond the Danube'. Suetonius lists his planned campaigns as 'the Caspian Gates, the Ethiopian coast, and the sources of the Nile'. But we also have coins from 66-67 AD that show Nero in military dress — a cuirass and a spear — with the legend 'Decursio', which means a military exercise or review. So he was clearly projecting a martial image, even if he never fought in person. Luna: And the damnatio memoriae probably erased a lot of the actual preparations, right? Lucas: Absolutely. After Nero's death, his memory was condemned. Inscriptions were chiseled out, statues were melted down. The legion I Italica was renamed and its origin story was suppressed. So the full scope of his military planning is lost. What we have are fragments — a mention in Pliny, a line in Tacitus, a damaged inscription from Moesia. But those fragments hint at something enormous: a vision of Roman expansion that might have changed the course of European history. Luna: It's a classic what-if. If Nero had lived and succeeded, maybe there would have been no Dacian Wars under Trajan, no Marcomannic Wars later. The whole shape of the empire might have been different. Lucas: Exactly. And the Danube would have become a Roman lake, like the Mediterranean. Nero might have been remembered not as the mad emperor who fiddled while Rome burned, but as the conqueror who brought civilization to the barbarians. Instead, he's a cautionary tale about ambition without execution. But I think there's something poignant in that — a man who dreamed of outdoing Caesar, but couldn't get out of his own way. Luna: So the next time someone calls Nero a madman, I'll mention his Danube dream. Maybe not mad, just... overreaching. Lucas: Overreaching, yes. But also, in a way, visionary. The Roman Empire eventually did push to the Danube and beyond — it just took better emperors to get there. Nero's tragedy is that he saw the horizon, but couldn't reach it.
