They didnt quite reach their natural boundaries tho. In the north, germania and all of britain + maybe even Jütland would have been feasible, but it wasnt worthwile. They tried both once, failed, and never tried again. But they could have. To the south they could have conquered Nubia, Fessan, and Western morocco. Again they tried the first two of these once, but failed and never tried again. They could have also expanded along the coastal Red sea as the ottomans did. Then, finally, they could have conquered all of pannonia and dacia and establish their border on the carpathians. This one is the most puzzling to me why it never happened, as countries that came after the romans always had their borders on the carpathians. So all in all there was still some space for expansion; and maybe if they did and reached their natural borders, they would have become like China.

Joseph Tainter's "The Collapse of Complex Societies" is also a good explanation. The basic idea is: diminishing returns. The greatest returns on investment (manpower, resources, gold etc.) are at the beginning of expansion and growth. And some institutions always tend towards becoming more and more complex over time (government bureaucracy, as just one example). Over time the returns diminish while the costs increase. At some point the returns pay the expenses with no surplus, while the costs are so great that the entire economy is running to stand still. That's where complex societies become vulnerable to crises they can't deal with.

Its funny that the supposedly "too complex" roman empire lasted far longer than its "superior" simple neighbors.

Especially when we consider most states fail to exist for more than 200. Edit: I also think of china, a society that is incredibly complex at the same time as rome. It had its ups and downs but always managed to reconsitute itself. I would think it was only due to the complexity of the chinese state that it was able to keep itself together (with periods of great disunity) and not collapse.

@@ldubt4494 Conquering and holding land are two very different things, however.

[@silverjohn6037]

There's an old Rudyard Kipling poem, The Lost Legion, that begins, "There's a Legion that never was listed, That carries no colours or crest, But, split in a thousand detachments, Is breaking the road for the rest." It was basically about traders and adventurers that, over centuries, built the British Empire but it could also apply to the Roman Republic. It wasn't just the grand politicians that built the Republic to it's peak for the Empire to inherit, it was also the younger sons of the landed gentry seeking opportunities and retired legionaries taking land grants in the conquered territories that "Romanized" their neighbours through intermarriage and building social and economic ties. With the fall of the Republic the landed class grew smaller and the Empires discouraged the survivors from straying too far out of sight and building a power base outside the Emperors' control. Without fresh blood from Rome the old connections grew weaker until the people living at the border regions had more in common with the barbarians outside the borders than the elite back in Rome.

When it comes to central eastern and northern borders, I would say the main factor was likely the law of diminishind return: to conquer and most importantly maintain inhospitable and mostly non-urbanized areas not very suitable for extensive agriculture and not easily taxable was essentially not worth the resources necessarily to do so. And the further the expansion in outer areas with not pre-established cities and road systems, the more challenging to have the central infrastructures and communication work properly. Also, further expansion North East would mean more military efforts to settle revolts, more potential usurpers.

If the Battle of Teutoberg Forest never happened, do you think Rome would have held on to the land between the Rhine and Elbe long-term? While it was sparsely populated, that means more land could be granted to veterans who had finished their term of service (colonies).

[@Brian-----]

I think if there is one big explanation, it's because more expansion just didn't pay in hard money or the ROI was negative or unsustainable: for example, Dacia had known gold mines, so it was worth crossing the Danube to seize. I think at each point along the frontier, the question also had a local answer. Scotland and Ireland were just not worth conquering and even England and Wales were only marginally valuable. The Rhine and Danube saved money and time on logistics (as did the Mediterranean at center) and those two big rivers naturally kept barbarians out or from coordinating well after making a crossing. I'm not sure conquering Germania to the Elbe would have made much difference overall, and I don't think Bohemia's gold was yet known to exist. Persia blocked Rome in the east by force and the desert blocked Rome in the south by terrain.

[@TheSpecialJ11]

Yeah. All that would have been worth conquering in Germania in this time period would be anything close enough to the Rhine and Danube for easy transport to the coast. The moment you stray too far from a navigable river (with a nice port city at its mouth) then there's no way those foggy forests of Germany would be worth anything to a Mediterranean focused iron age civilization. Arguably Rome had more to gain in the Black Sea, but the difficult to defend and irrigate steppe prevented the great potential of what is now Ukraine to be realized until the Slavs came in with gunpowder and early modern plows to do so.

[@andrewsoboeiro6979]

Bret Devereaux (whom I believe you interviewed last year) emphasizes what a massive difference waterways make to preindustrial military logistics. Where you can transport food by sea or river, your army can operate over much greater distances and for much longer periods of time than when you need to transport it over land, because ships, unlike human- or animal-driven land transport, can carry food without consuming food. Thus, it's no surprise that the Roman Empire was largely confined to the Mediterranean coast; the few territories it had that weren't along the Mediterranean were largely accessible either by major river systems or from the Atlantic.

[@agagqbq]

i think a big reason for the location of the Roman territory is that the Mediterranean Sea(Mare Nostrum = Our Sea) is the most important aspect of the empire. Controlling the whole coastline meant you had a vast trade income while at the same time making the port cities super wealthy which could then be taxed. Furthering the borders beyond that(Ghaul, Dacia, Middle-East) is mainly beneficial to subdue future invasions.

A few things I learned from playing the game "Knights & Merchants" (A Real Time Strategy game with a heavy focus on the civilian side of food and production.) -Expanding your territory without a MASSIVE surplus of food will create a famine in an otherwise healthy civilization. -The Military is a surprisingly parasitic branch of society. It pulls massive amounts of food and resources from the rest of your civilization, and gives very little back in return. A military is necessary because it provides protection, but it steals food and supplies from your agriculture and production arms, which are both of far greater benefit to the civilization as a whole. -The more land you control, the harder it is to keep it. And since the military is so parasitic on the economy, and it takes time to travel from one border to the other, you are often times given the choice between "Feeding the parasite" by creating more armies, or withdrawing your forces back to a position that you can more easily control. Once again, I'm only discussing the way things work in a computer game, not real life, However, it seems to be knowledge that parallels fairly well. And it's knowledge that strongly affects my views on questions like "Why didn't the Roman Empire expand further?" (Next up, what Morrowwind taught me about evolution! 🤣🤣🤣)

Empire's have one enduring trait that is common to them, that is while typically created by conquest and engaging in frequent warfare: Empire's DON'T CONQUOR. At the end of the day the fundamental issue is that an Emperor benefits little from adding new land to his empire. Even a wealthy kingdom adds little when compared to the massive empire they already possess, by contrast the emperor is personally responsible for managing and integrating any new territories as well as paying for all that process. Huge headache for little gain. Most wars focus on non-territorial gains, with territorial gains more about security then conquest. Usually only the founder and maybe it's immediate successor engage in any significant expansion. We can see this in the Mongols, We see it in Charlemagne, we see it in china, in Persia, so on and so forth. I think the Ottomans lasted the longest for continuous conquerors although even this slowed rapidly. Indeed one of the notable things about the British/European colonial empires is that they were driven by independent nobles and politicians (e.g. east india company) not the rulers.

There was also the problem that the further out a province was, the harder it was to control politically from Rome. There were a lot of serious rebellions in the more distant provinces, either by the populations there, or by governors who felt they should be kings or even emperors. What’s really interesting to me is the border with Parthia/Persia. This lasted from the Roman Republic, through the Empire, and continued to the Byzantine period, neither side able to decisively defeat the other despite numerous wars. And that same border existed between the Ottoman Empire and Persia, again for hundreds of years of wars. You would think this would mean that border was really hard to overcome from both the East and the West. And yet the early Muslims stormed out of Arabia in the early 7th century and crossed that border in BOTH directions, defeating the Byzantine empire and defeating and conquering the entire Persian empire in just a few years. It’s one of the most bizarre and impressive episodes in history, right up there with Alexander’s conquests, the Mongol conquests, and the conquest of much of the world by relatively small and distant European states like Portugal and Britain.

It's not bizarre at all, both empires just had gotten out of the last Sassanid-Byzantine war, which left them both very weak.

Another thing is that you defeat a kingdom's army, and replace the king with your guy, you can pretty much use the existing system and annex the kingdom. Later you can tweak it to match your own administration. If the land is of villages which raid and kill each other, you need to defeat and control them separately, change their way of life, and they still don't produce much that you value. Except perhaps for soldiers, you can recruit barbarians in your armies instead of your own citizens, and I see no way this could possibly backfire.

Wdym "deserts and wastelands"? Mesopotamia was THE most fertile region in the ancient world and one of the most densely populated.

[@nikolatasev4948]

@@yaqubebased1961 By "deserts and wastelands" I meant the parts of Afrika closest to Italy, the Germanic and Pict tribes. You are absolutely right, Mesopotamia was incredibly fertile, but getting to it was very challenging logistically. It would mean an incredibly long overland march over hostile terrain (which Rome as a land power preferred), or a second sea voyage over unfamiliar seas. While not impossible to invade (Trajan and Julian did so), it proved very difficult to hold. Perhaps if they tried to capture and hold it bit by bit, instead of take it all at once they would have been more successful. On the other hand, a province so far away would not count on timely support against enemies, and with constant political turmoil would be very difficult to keep loyal.

Could you please elaborate, on how Europe of today, would have been different IF had Publius Quinctilius Varus NOT been defeated by Arminius? I remember back in 1987, when the main battlefield in Kalkriese was found. It was here that the Empire ended, and I have wondered since then, HOW would Germany/Europe would have developed IF this battle never took place.

[@RemembertheKrell]

The Roman empire didn't end at Teutoburg. Varus' defeat in 9 AD was a temporary set back at worst. Roman legions under the command of Germanicus actually reinvaded northern Germany and inflicted multiple defeats on the German tribes in 15 and 16 AD. Arminius himself was later killed by his own people due to internal tribal politics. Moreover, Rome continued to expand and conquer new territories over the next century. For example, they invaded and conquered Britain in 43 AD and Dacia (modern day Romania) in 117 AD. It's doubtful a Roman victory at Teutoburg would have changed history much. What really halted Roman expansion was economics. It cost Rome a lot of money to maintain its army, garrison and administer its provinces, and build and maintain the road system that connected the empire. Simply put, there wasn't much of economic value in Germany to make it worth while for Rome to conquer and hold it. While Britain had tin mines, Dacia had gold mines, Egypt had grain, and the East had valuable trade routes to the Orient, all Germany had was forests and swamps. A similar thing happened when the Romans later invaded Caledonia (Scotland). There after initial victories they eventually withdrew as the cost to garrison the country outweighed the economic benefits. Ultimately, what caused Rome's destruction in was a combination of political decay, high taxation and inflation, and large scale human migration into Europe. By the 5th century Rome simply couldn't afford to keep a large enough army in the field to defend against the barbarian incursions. A key factor was a growing Roman reliance on allied tribes (foederati) to provide troops free of charge to defend the frontier. Over time the foederati grew more and more powerful and carved their own mini kingdoms inside Roman territory. By the 420s large parts on the Western roman empire were controlled by the Franks and Vandals. The Roman Army was simply too small and too weak to do anything about it. Fifty years later the empire was kaput.

[@Brian-----]

I think it would not have made a big difference. Germania lacks gold, was forested, had more swamps and bogs, is hilly, and has a harsher climate than Gaul or southern Britain. It also always would have been less secure, and so more expensive to defend. I think it never would be a priority for Rome to Romanize or develop Germania or at least the accessible part between the Rhine and Elbe. Bohemia has gold but I don't think it was yet discovered in Roman times.

[@Reaper08]

The Romans still wouldn't have conquered Germania as it was simply not worth conquering. As chrismace2221 already said, it was economics that largely halted Roman expansion. Maintaining an army of 430,000 men and the supporting infrastructure is not cheap. Trying to annex new territories that held little economic value wouldn't make sense. Contrary to Hollywood movies, the Romans don't try to conquer the world and expand just because they can.

[@gengis737]

I never noticed, but northern frontier of Roman Empire followed the limit of continental climate, with icy winter, while all of Mediterranean and Oceanic climates, with mild winter, are within the empire. Although perfectly livable today (but producing no olive oil, and very few wine), perhaps continental winter did not suit well for Roman time agriculture or was too lengthy and harsh to sustain warming and feeding large cities. Except by using Rhine and Danube river to supplement it. The same happened much later in Baltic countries : they were thinly populated with no major city until ships became large enough to carry large amount of food traded for wood and fur.

[@paolomarega3790]

Whenever I talk about Roman expansion, I always differentiate in three categories: Roman Republic, Augustus and Roman Empire. During the Republic, the aggressive expansion of Roman territories was indirectly fueled by Rome political system. The consuls had only one year to prove their worth and military conquest was definitely the easiest and shortest route. It's no wonder why Roman republic was almost constantly in war with somebody else for almost 500 years. In the later Empire, there were only two reasons for expansion wars: consolidation of power and economic reasons. "Weak" emperors used the expansion war as an argument to strengthen their position in Rome and gain the favour of Senate and people. A successful example of this strategy is the conquest od Britain by Claudius. On the other side, the bad financial state of Roman Empire forced many wars with the only goal to get some treasure to boost the economy. Look at Trajan: he had no reason to invade Dacia but to bring back to Rome the rich golden treasure they had (a two-week long convoy af carriages full of gold, if I remember correctly). The only Roman being with a different mindset was Augustus (and that's why he's the best emperor of all). He understood that the Roman State (during the transition between republic and empire) needed stability; in addition, he even understood that said stability could not be achieved until the hostile population at the borders of the state were pacified, either by diplomacy (like Parthians) or war (like Germans and Arabs). The German campaigns of Tiberius, Varus and later Germanicus had the goal of preventing the Germans from breaking the stability of the borders. If Teutoburg didn't happen ( or better, if Germanicus was allowed to continue his campaign), Germany would have ended up being a Roman province fornthe centuries ahead and the Northern border would have been way more stable (with a ton of positive consequences for the later empire).

Matches pretty well with what Tainter says in "the collapse of complex civilization"... they had conquered all the territories that made them more money than they cost them. Further expansion (and even some of the expansion they did) was a net-negative economic prospect.

[@countottovanshanoo822]

"Why Did the Roman Empire Stop Expanding?" In-fighting and private armies that held allegiance to their generals rather than the state, they put all their efforts into civil wars rather than protecting/expanding the empire.

[@jacquesmertens3369]

There may have been unlimited land to conquer, but there was no unlimited supply of Roman soldiers or mercenaries. Also, as you move further away from Rome logistics become an issue. Additionally, in 30 BC the Roman army switched from conscription to recruitment, just like our modern armies. Pretty soon mercenaries made up 50% of the army. Further expansion would have required more money, for almost no extra return. Last but not least: Roman soldiers far away from home had relationships with local girls. They were forbidden to marry them until the reign of Emperor Severus (192-211 A.D.), but the mix which had resulted in the romanisation of the locals also meant that the soldiers were no longer available to be stationed elsewhere. Mixed marriages made the borders fade away. The military conquest was over, but the Romans had left their cultural mark.

"Started wars and annexed territory for Rome's glory, and their own." Right off the bat, you make a catastrophic analytical mistake. Rome's wars of conquest were a path to wealth for individuals, particularly after the full professionalization of the Legions under Marian. It's a mistake to believe that anything else, particularly sentiments like "glory" were a motivating factor. Money was power, and vice versa in Rome.

[@doppelwaffen]

The republic expanded constantly because war was a racket. It enriched the senators (who happened to decide upon war and peace) to the expense of the public. We may call it the military agricultural complex. The senators gained slaves, real estates, and markets. For instance, Rome used its legions to enforce an Italian monopoly on wine production. Things changed with the principate. The emperor would use his legions to further is interests and he would not engage in costly wars which did not pay off.

[@UGTLDG]

Great subject! The simple answer is that Rome would not expand further, because it was economically unsitable. In order to expend, a state would require more and more soldiers to conquer and occupy new territories. Those armies would require more and more resources to remain loyal. Those resourses had to come up from those new territories, but this couldn't happen because those areas were underdevelopped (Parthia Excluded). The Romans first would have to wait for centuries for these areas to grow wealthy enough to worth the effort and resources conquering them... With frost to the North, desert to the South and the ocean to the West, the only quadrant that would worth trying expanding was East towards Parthia, but that state was particularly hard to conquer due to the different tactics they employed in battle, using quite large proportions of excelent cavalry, a weapon the infantry-based Roman doctrine always had trouble to cope with. Rome (in the form of the Eastern Roman Empire or Byzantium) finaly DID won the upper hand at last, in the 7th century AD, after adapting to their fighting style with their own excellent cavalry detachment. But the timing was terrible: the Arabs storming out of the desert, another logistical nightmare for Rome, fell upon both combattands at a time when they were exsausted from their infighting. Byzantium managed to hold its own but Persia was overrun in a short period, adding all its resources to the Arabs (including those excellent cavalrymen), rather than the Eastern Romans who counted on them after a hard fought war... The years that followed, Byzantium lost a huge chunk of its eastern territories to the Arabs, setting a case study of why an empire should NOT overreach, and how wise the old Romans were for NOT succumbing to greed. The history of Alexander also pinpoints how difficult it was to reach that far, with the means of the time! It took him (and his army) 10 long years to conquer Persia and admittedly cost him his life! At a time when horseshoes did't even exist, even the cavelry had to dismount and walk most of the way, from village to village and from battle to battle! Soldiers would litteraly grow old fighting a never ending war, never to see their homes again! That was NOT inspiring, to say the least! A king could perhaps muster enough willpower, but how to transmit that to motivate simple soldiers, that was a lost cause, before modern transports (like loccomotive) became available.

[@barrybarlowe5640]

Inertia, to some degree. Imperialism pushed expansion, because examples of Roman might, and the absirbtion of loot from the conquered helped sustain the empire. But as the victories occurred further and further away, and less loot made it back to Rome, this enthusiasm dwindled. Also, being rich meant being near the seat of power, and that meant huge bribes to Imperial coffers. It also meant incredible danger from mad, greedy emperors, their sycophants and getting involved in the latest plot to usurp power. Eventually, military action at the Empire's borders was to simply protect what they had acquired, while wealth was made through trade.
