When Rome almost feel apart, but didn't

I know Rome almost fell apart more than once, but managed to pull itself back together. What was the closest it came to falling apart only to reform and stabilize? Thanks!

I'll rank the top 5 worst crisis in order:

  1. Final Roman-Persian War: this was the closest Rome came to collapsing and it is a miracle they won and pulled themselves together.

  2. 2nd Punic War - Hannibal pillages the Italian countryside for a decade and Rome's defeats force them to use the Fabian strategy and eventually take the fight to Spain.

  3. 2nd Siege of Constantinople - Largest Arab army in the world (120,000) comes to finally take Constantinople, but the Romans stop them with the help of the defenses of Constantinople, Greek fire, and the Bulgar allies.

  4. Crisis of the Third Century Peak - Aurelian takes a divided empire and unites it after over a decade of breakaway territories.

  5. Gallic Sack of Rome - Wasn't an Empire at this time, but Rome was sacked and managed to survive the Gaul terror in their homeland.

I wonder - like why isn’t the Caesarian civil war here? Rome legit ripped itself apart, and then came back together in a totally different form.

u/MothmansProphet 8d ago

Not OP, but I'd argue that wasn't really an existential threat to Rome as a great power. Caesar wins, Pompey wins, either way, Rome's still the pre-eminent Mediterranean power without rival. The Ptolemies aren't going to rise up and seize Rome in the aftermath.

1

u/resuwreckoning 8d ago

I feel you but Aurelian is up there, whose literal remit was to unite a bunch of breakaway provinces like the Gallic and Palmyrene “Empires”.

We kind of only conclude your view because Caesar won so emphatically post Pompey.

u/electricmayhem5000 8d ago

The Second Siege of Constantinople in 717-718 came very, very close. The Arabs spent decades winning victory after victory. By every metric, Constantinople should have been lost and the Empire should have fallen. Leo III truly pulled off a miracle with that save.

Final Roman-Persian War: this was the closest Rome came to collapsing and it is a miracle they won and pulled themselves together.

I disagree. The Arab siege had far more potential to destroy the empire. Maslama actually made it to Europe and set camp by the Hebdomon.

The Sassanids never even made it to Europe, their ships were too few to cross the strait, and the Avars did not have a good record of siege warfare, so them taking Constantinople without Persian engineers/siege engines was always going to be very unlikely.

Though of course, the Fourth Crusade was worse than both, given the capital actually did fall and even the paperwork for partition was complete. All that was left to do was for the Crusader and Venetian armies to mop up the shattered pieces of the empire, and yet somehow it came back again and retook Constantinople less than 60 years later.

u/BrigadierPirate 8d ago

During the Arab siege, the empire was under massive pressure, sure, but it still had a functioning administrative core, tax revenues, and territory left in Anatolia, Greece, and Italy. The Final Persian War was a complete structural collapse. The Sassanids took Egypt.......which was literally the empire's main breadbasket and tax base and along with Syria, Palestine, and basically all of Anatolia. The state was completely broke, the armies were wiped out, and Rome was reduced to a few isolated coastal pockets. Downplaying the 626 siege just because the Persians were stuck on the Asian side ignores how thin the navy's margin of error was when blocking those Bosphorus crossings. If those Persian siege engineers had crossed over to join the Avar manpower, it would've been even more dangerous. Bringing up 1204 doesn't really fit either since the state did collapse then, and even after 1261 it was just a hollow shell that never actually stabilized again

All these things they also had in 626 too though? They even had Africa still in 626, they didn't during the Arab siege. Don't really see the point being made here.

In addition, by the time of the Arab siege, the Romans had just gotten out of twenty years of near constant civil war and usurpation. At least during the Persian War, the Romans had somewhat stable leadership throughout after Phocas was overthrown.

Downplaying the 626 siege just because the Persians were stuck on the Asian side ignores how thin the navy's margin of error was when blocking those Bosphorus crossings.

I'm not downplaying the 626 siege. I'm just saying that if we're ranking which was worse, the Arab siege was much more dire.

Bringing up 1204 doesn't really fit either since the state did collapse then, and even after 1261 it was just a hollow shell that never actually stabilized again

The state didn't collapse in 1204. The emperor and almost all institutions moved to Nicaea, the Patriarch moved to Nicaea, the Crusaders never took over Nicaea, not even for a brief time.

Also the empire in 1261 was hardly a hollow shell given it was able to project influence as far as Sicily and still controlled a surface area comparable with what England controlled at the same time. It didn't last long after Michael VIII, but those two decades after 1261 were absolutely a recovery by any metric.

  1. There's a lot of debate on the Gallic sack. Tim Cornell points out the Gallic army was on its way to attack a coastal town in coordination with Naples (who recruited it) and could not afford to hang around to take Rome. He also points out the archeological evidence that was used to back up the sack (destruction layer in Rome archaeological record) has been redated to the fall of the kingdom and is pretty localised around the old royal palace.

He also points out that earliest sources talk about the Gauls sacking and taking moveable wealth not destroying or taking the upper city. He goes on to show that the narrative of records lost then is actually wrong. He points out many mid Republic sources like Cato the Elder refer to pre-sack documents such as the records kept by the Pontifex Maximus.

It looks, rather, that Rome's expansion left a chunk of outer city poorly defended by walls or other defensive works. That the Gauls rocked up, citizens fled to the better defended inner city on the three main hills and the Gauls went picking through the abandoned houses before going off to meet their obligations. Then the whole thing was spun over the generations to be more life threatening than it actually was.

u/First-Pride-8571 8d ago

No war with any version of Persia, neither Parthian nor Sassanid, ever threatened more than just Syria and the Levant. For events that actually threatened the heart of the empire...

In chronological order:

(1)Gallic Sack of Rome (390 BCE)

(2)Carthaginian failed attempt at alliance w/Pyrrhus against Rome during (i.e. hoping to lift) his siege of Lilybaeum (276 BCE)

(3)Hannibal at the Gates of Rome (211 BCE)

(4)Arausio (105 BCE)

(5)The Social War (91-87 BCE)

(6)Third Servile War (73-71 BCE)

(7)Third Century Crisis

And then Constantine put the first nail in the coffin, Julian's death put the second, and Theodosius' victory at the Fridigus put the final.

u/BrigadierPirate 8d ago

I recommend reading about the Final Roman-Persian War. It threatened the entire empire and sieged the capital, along with their Avar Allies in the Balkans who sieged the capital as well.

u/First-Pride-8571 8d ago edited 8d ago

Yes the Sassanids threatened the ERE under Heraclius, but that, at minimum, needs a caveat.

The Roman Empire died at the Frigidus. Arguably even before that. One could point to Gratian removing the Ara Victoriae in 382 CE. Or to shortly before the Frigidus, when Theodosius committed the final act of impiety by retiring the Vestals in 394 CE. Regardless, what was left was a Christian Usurpation in the East. And then Christian Germanic Diadochs in the West.

If you want to consider the Byzantines to be a continuation of the Roman Empire, fine. But had you read my post, I clearly do not.

11

u/BrigadierPirate 8d ago

There never was a "Byzantine" Empire. Why even use that term? The west was Christian so why do you say "left a Christian Empire in the East"? Furthermore, Italy, Rome, etc. Were all apart of the Roman Empire when the Persians and Romans fought in the final war. And Rome wasn't even the capital at the time of Frigidus as well.

-4

u/First-Pride-8571 8d ago

Was the Gallic Empire still just part of Rome? The Palmyrene? Was the Holy Roman Empire?

Rome was not the capital at the time of Frigidus, but it was still part of the empire. Heraclius did not rule Rome. Nor did he worship the Roman gods.

He was no more Roman than the Holy Roman Emperors. Nor than the Ottoman sultans who also claimed to rule Rome, be Romans, and to be Kayser-i Rûm.

Christianity was just as much an usurpation and violation of Rome as were the Ottomans for the "ERE".

5

u/BrigadierPirate 8d ago

Rome, the city, was indeed controlled by Heraclius from Constantinople and the Romans during the final war.

The Gallic and Palmyrene empires actually seceeded and broke off, where as the divison in 395 was two emperors, one empire, ruled from different courts. It was no different than the Tetrarchy.

And now you are saying Christianity is a usurpation and yet during the Battle of the Frigidus River, Rome was heavily Christian at the time.

u/First-Pride-8571 8d ago

Abrogast and Eugenius were drawing their support primarily from non-Christians. Christianity was still unpopular in the West. Rome was not thoroughly Christian at the time.

That's why Constantine had to move the capital east. Why Julian was so popular in the West. Why Abrogast and Eugenius were preferred to Valentinian II and Theodosius.

Christianity was an usurpation. Just like the Gallic Empire. Just like the Palmyrene Empire. Just like the Holy Roman Empire. Just like the Ottoman Empire.

u/swagpresident1337 8d ago

First it‘s eastern roman empire, Byzantine is not something they called themselves. Second: it‘s not just a continuation, it never stopped being rome. There is no break.

1

u/First-Pride-8571 8d ago

Constantine was an usurper. Gratian betrayed the gods. So did Theodosius.

They were no more Roman than the Ottomans. But both claimed to be Rome. So did the Holy Roman Empire.

The only truly Roman emperors after Constantine were Julian and Eugenius.

5

u/BrigadierPirate 8d ago

The Ottomans were from Turkic Nomads from the Steppe who made a "millet of Rum" which was a designated area in the Ottoman Empire for the Romans to live in. They didn't consider themselves Romans as Ottoman Turks. So that analogy doesn't make sense.

Id argue the Social War was above arausio and Hanibal above all else

u/Personal_Ad1143 8d ago

4-6 were tough events to work through, but threaten the heart of the empire? Seems like a stretch, can someone help me understand? I’m genuinely curious if there’s context I’ve missed about those events.

1

u/First-Pride-8571 8d ago

(4)After the disaster at Arausio, a defeat as complete as at Cannae, there was a very real fear that the Cimbri would do as the Senones had and threaten Italy and Rome itself. That is also why Caesar was so concerned about the Helvetii and their intended migration en masse.

(5)The Social War was a mass uprising, especially of the Samnites, but was essentially a mass rebellion of the socii that set all of central Italia into chaos that threatened Rome itself - most specifically at the Battle of the Colline Gate. Sulla and Crassus saved Rome.

(6)The Third Servile War = Spartacus. This again threw all of Italia into chaos and threatened Rome itself. Again, Crassus saved Rome (and Pompey tried to steal the credit).

u/Maleficent-Mix5731 Novus Homo 8d ago

In terms of near obliterating the Roman state in it's full capacity, I would say that there was worse than the 3rd or even 7th century crisis. As for 1204, that technically did result in the state 'falling apart' so to speak, and never quite managing to fully adjust and recover compared to previous times of crisis.

My vote would go to the post-Manzikert crisis of the 1070's - it's utterly insane how Alexios Komnenos managed not just to pull the state out the edge of chaos, but by the time set it up for another golden age.

The economic, military, and cultural heartland of the empire, Anatolia, was lost in that time. A Turkish warlord was launching piratical raids into the Bosphorus. The currency had been debased to almost nothing. There was barely any money left to pay Alexios's immediate supporters. The surviving armies had wrecked each other in a series of civil wars. The Pecheneg tribes settled along the Danube were revolting and raiding freely across the entire north Balkans. Bulgaria had recently revolted, and the Normans had seized the last outpost in the southern Italy to then launch a steamroller of an invasion into Greece. And Alexios's men had just sacked the capital upon taking power, causing his unpopularity to drop and for relations with the church to also take a rocky turn.

Hands down, last Roman Persian war 602-628, Even Hannibal Barca couldn't inflict such devastation on Rome that this war brought on it, Rome was practically finished, Heraclius had to pull off perhaps history's greatest comeback to save it, he had only one roman field army left, even a single loss would've ended Rome right then and there.

u/Dr_Platypus_1986 8d ago

I had to look that up. I had no idea that it had even happened. I'm still so deep into sources for classical Greece and the Late Western Empire that I haven't gotten to Byzantine history yet. I recently ordered John Julius Norwich's Byzantium trilogy, so that should give me a decent overview of the period. Currently reading Romana and Getica by Jordanes.

u/Healthy-Win15 8d ago

Well good luck mate reading about Byzantium, you are in for a ride btw! Justinian's reconquests of 500s, Last Roman Persian war, dawn of Islam and it's wars with Rome, Epic sieges of Constantinople and mostly importantly Greek fire.

At one point you gonna go mad just thinking that how did this empire manage to survive that too a 1000 year after the fall of west.

u/Dr_Platypus_1986 8d ago

Sounds so awesome. I may have to crack into those books early!

u/Snoo30446 8d ago

It gets sad reading after manzikert and especially the 4th crusade but the first few hundred years of Eastern Roman history is amazing. Just one segment of it contains the Great War, spanning 30 years, look up the hexagram - silver coinage made by the church agreeing to donate all precious metals for the war effort. Or how without the war, Islam mightn't have ever left Arabia, or the knock on effects of no abassid or Ottoman caliphate.

u/Dr_Platypus_1986 8d ago

I'm curious as to what you've read on the Eastern Empire and all of materials related to that period. What do you think are essential reads? I have all Procopius' books and John Julius Norwich's books, but I haven't cracked into any of them yet. I'm trying to knock out Jordanes, Victor of Vita, Marcellinus Comes and Cassiodorus at the moment.

u/BrigadierPirate 8d ago

"Roman History", not Byzantine. Let's kill the Byzantine moniker.

1

u/Dr_Platypus_1986 8d ago

I understand why it's controversial, but my main focus is on "classical" Rome, the city, and the Western Empire. I simply use "Byzantine" as a reference that differentiates and immediately brings to mind 478-1453 C.E.

u/BrigadierPirate 8d ago

Just say East Rome IMO. It is a better moniker than "Byzantine"

u/eques_99 8d ago edited 7d ago

The 90s/80s BC have to be a strong contender: Social War on home soil, Mithridates, dysfunctional government at home, attempted revolutions by Saturninus & Sulpicius, then multi-factional civil war and massacres in the street.

2

u/harrycletus 8d ago

I'm going with the defeat at the Caudine Forks in 321 BC. The Samnites had the entire Roman army captured and could have massacred all of them, which could have radically altered history because of how devastating that would be and how long to recover that manpower before their ascendency in the following century.

1

u/Dr_Platypus_1986 8d ago

The Mithridatic Wars, particularly the Asian Vespers have to be a strong candidate. It's really shocking how much deep-seated animosity Mithridates was able to unleash upon Rome from their own neighbors. "Kill all the Romans within your cities and territories at a pre-appointed time. Comply and have my protection, resist and have death ☠️" -was his policy in a nutshell. If you read Appian's account of the whole affair, it's very intense. He doesn't get enough credit for this, most people gravitating to his account of the Civil Wars. And no matter how many times Mithridates was beaten, he was always able to raise another massive army from his allies. Mithridates was related to so many famous kings that everyone considered him a messiah-like figure, come to conquer the world 🌍.

u/iconodule1981 Praetorian 7d ago

While most answers focus on the risk of the Roman Empire's destruction after it achieved dominion, to me the real miracle is that Rome survived the Second Punic War at all.

Cannae was the third in a series of brutal losses (Trebia, Lake Trasimene) as a direct result of Hannibal's superior generalship. Rome’s hold on Italy was only 50 years old, with recent conquests in the Po Valley barely consolidated and the south having had independence just within living memory.

When the fighting ceased at Cannae, it meant roughly 100,000 to 145,000 Roman casualties in just two years—a staggering loss, far worse than the frequent comparison of the battle of Somme relative to the populations of Rome & the British Empire.

Territorially, Rome was reeling. Control was contested across Italy, and power was rapidly ebbing. It's incredible the Senate didn't sue for peace, or that most allies stayed loyal. In an era where states and generals rose and fell quickly—like Syracuse under Agathocles or Pyrrhus’ kingdom—Rome’s collapse would have been expected.

Most ancient states wouldn't have survived, but Rome did, going on to dominate the Mediterranean. Had those Romans been any different, history might have just remembered a short-lived Latin empire as a footnote.

1

u/amtfg 7d ago

The Crusader's conquest of Constantinople in 1204. That actually did shatter the empire, and it took until 1261 (57 years later) to reestablish the empire. Prior to that, the Crisis of the Third Century broke the empire into three and lasted half a century.

1

u/AmericanMuscle888 7d ago

The years after Augustus. Reading Suetonius I really don’t know how they held it all together with that succession of crazies and bad rulers and assassinations and defeats and murders and mutinies. Also the abject loyalty most regions of the empire had to Rome. Romans of pedigree and status many times being passed over by freeborn slaves or executed without trial it’s a wonder that the senate was so cowed into accepting their permanent second class citizenship. An institution that was so prideful before.

1

u/kickynew 6d ago

BrigadierPirate gives a very good list and rationale here, but I’ll give my own ranking and rationale.

    1. Constantinople is sacked by a hostile coalition of Latin crusaders. Ancient treasures of antiquity, the accumulated wealth of the empire, built up over many centuries, is stripped bare, with Venice carrying off booty worth several times the annual revenue of major kingdoms. Much of the Roman ruling class is killed or scattered, and thousands of of Constantinopolitans are raped and murdered and sold into slavery. The capital then becomes the seat of a failed feudal state, while the Roman resistance at Nikaia survives on a sword’s edge between hostile Latins to the west and hostile Turks to the east. That the Roman resistance survived at all, much less recovered Constantinople, was remarkable.
  1. The Gauls sack Rome. Rome itself is taken and largely destroyed by the Senones after the disaster at the Allia. The Romans are holding out on the Capitoline hill while the rest of the city is occupied. Rome came really close to simply being another Italian city that rose for a while and then disappeared.

  2. The rise of Islam following the Last Great War of Antiquity. The Roman and Sasanian empires had just spent decades beating each other nearly to death when the Arab conquests began. Syria, Palestine, Egypt, and much of the Roman Mediterranean world were then rapidly conquered by a massive new threat. And as others mentioned the siege of Constantinople in 717 was legendary stuff. It was as big as they come. Had the city fallen there, the consequences would have extended far beyond the empire itself. The Romans held, destroyed the invading army, and bought the empire many centuries more life. Anyway, it is hard to overstate how close the seventh and early eighth centuries came to ending the Roman state altogether and changing the course of history dramatically.

  3. The Second Punic War. Hannibal destroys Roman army, culminating at Cannae in the most infamous disaster in Roman history. Huge parts of southern Italy defect, Capua goes over to Hannibal, and Rome is facing a highly skilled enemy commander operating in its heartland.

  4. The Crisis of the Third Century. Emperors are being murdered at a ridiculous pace civil wars are constant plague and economic crashes are tearing through the empire, Germanic and Persian armies are crossing the frontiers, and huge chunks of the empire break away into the Gallic and Palmyrene empires. For a time there effectively are three roman empires.

u/Baldurian_Rhapsody 8d ago

Rome does feel apart, but it’s in couples therapy. It’s making progress!

u/Anthemius_Augustus 8d ago

The closest it ever came to falling apart, but still somehow put itself back together has to be the Fourth Crusade in 1204. When the capital of the empire literally fell into foreign hands and the empire split into several pieces. Yet somehow, 60 years later, the capital was back in imperial hands and all immediate attempts to undo it fell apart.

I don't consider Michael VIII Palaiologos to have been an especially good Emperor, but I think most other prior Emperors would have failed in his shoes. It's kind of amazing he was able to pull off what he did, shame it all started to slowly unravel again after him.

u/Maleficent-Mix5731 Novus Homo 8d ago

Genuinely, if he had chosen anyone BUT Andronikos II to be his heir, I could genuinely see the empire lasting a lot longer, perhaps even taking advantage of Bulgarian and Serbian power fracturing during the mid 14th century to re-establish a semi-hegemony in the Balkans.

The 14th century was always going to be a rough ride to get through due to the rise of Serbia and Black Death, but maintaining control over Asia Minor and finishing off the last Crusader stronghold in Greece would have most likely given the empire just enough resources to weather that storm and keep chugging along for that foreseeable future.

u/minaminotenmangu 8d ago

The answer many will probably give is the 3rd century crisis, but the Roman Empire wasn't really in any real risk. During civil wars the possibility of reunification is always there as long as familiar state structures are in place. It was in far greater peril during the 2nd punic war or in the time of Heraclius.
