A Basic Introduction To The Ancient Roman Political System
QotD: The changed role of the Dictatorship in the late Roman Republic
And then the dictatorship sleeps, for 119 years. The Romans don’t appoint any dictators at all during the second century, despite appointing, on average, one roughly every four years for the first three centuries of the republic. And then in 82, L. Cornelius Sulla Felix “revives” the dictatorship.
Now, precisely because we are now talking about the irregular dictatorship, there really is no way to lay out its features except to go through its uses. Fortunately, there aren’t that many.
In the spring of 83 BC, Sulla, who had been notionally serving in a proconsular command in the East to fight Mithridates, landed in Italy with his army; Rome had effectively come under the control of a military junta initially led by Gaius Marius (cos.107, 104-100, 86) and after his death by L. Cornelius Cinna, Gn. Papirius Carbo and Gaius Marius the younger (son of the former). Sulla openly fought the consuls of 83 (Gaius Norbanus and L. Cornelius Scipio), pushing towards Rome. As the year shifted over into 82, Carbo and Marius the Younger had themselves elected consuls. Marius was killed in 82 during the siege of Praeneste; Carbo fled to Sicily after Sulla took Rome (where he’d eventually be captured and killed by Pompey in 81).
Now this posed a problem, constitutionally: there were always to be two consuls and consular elections had to be presided over by a consul … but one consul was dead and the other fled. The customary solution to this problem was the appointment of an interrex, a five-day-long office which essentially only had the authority to hold elections for new consuls in the absence of consuls or an already appointed dictator. Prior to 82, the last confirmed interrex we know of was in 216, but there may have been another in 208, in either case this also a long-unused office. All the interrex is supposed to do is hold an assembly of the comitia centuriata which can elect new consuls; they did not have any further authority.
Sulla, sweeping into Rome, convened the Senate and directed them to select an interrex; one wonders if this was the same meeting of the Senate Sulla convened within hearing distance of his soldiers in the process of butchering six thousand captured Romans who had sided against him, in case the Senate imagined they were being given a choice (Plut. Sulla 30.1-3). In any event, the Senate selected Lucius Valerius Flaccus (its oldest member, App. BCiv 1.98) on the assumption he would hold elections; instead, Sulla directed him (with the obvious threat of violence) to instead convene the comitia centuriata and instead of holding elections, propose a law (the lex Valeria) to make Sulla dictator with the remit of rei publicae constituendae causa, “for reforming the constitution of the Republic” – an entirely new causa never used before. Of course with Sulla’s army butchering literally thousands of his political opponents, the assembly knew how they were to vote.
This is, to be clear, a thing that customarily the interrex cannot do. This is also not, customarily, how dictators are selected. The appointment of a dictator had not been recommended by the Senate and in any case has also chosen the wrong voting assembly (the comitia centuriata instead of the comitia curiata) and also the interrex doesn’t have the authority to nominate a dictator or propose a law that nominates a dictator. You may begin to see why I see this as a new political innovation and not a clear extrapolation from previous practice. None of this is how the customary dictatorship had ever worked.
The law also gave Sulla a lot of powers, which was important because most of these powers were not things that customarily a dictator could do. He could legislate by fiat without an assembly, something dictators could not do before. He was given the ability to alter the number of senators as well as choose new senators and expel current senators; a dictator had once been named, Fabius Buteo in 216, to enroll new senators, but had (according to Livy) openly noted he did not consider himself to have the authority to remove senators enrolled by the previous Censors (Liv. 23.23). Sulla rendered his authority immune to the acts of the tribunes, whereas that office had previously been the only office to exist outside of the dictator’s authority. Finally, his appointment had no time limit set to it, whereas previously all dictators had six months and no more.
What Sulla has done here is used new legislation (remember, Rome has no written constitution which could invalidate any new law) to create what was is effectively an entirely new office, which shared neither an appointment procedure, term limit, or set of authorities and powers with the previous version.
Sulla then made a lot of very reactionary changes to the Roman Republic we need not get into here, got himself elected consul in 80, and then resigned his dictatorship (after rather a lot longer than six months, making Sulla, by the traditional criteria, the worst dictator Rome had up until that point, though I doubt he saw it that way), and after that retired from public life. Sulla seems to have imagined the office he created out of thin air in 82 would be a thing sui generis, a unique office to him only, to that moment only. Which was incredibly foolish because of course once you’ve created the precedent for that kind of office, you can’t then legislate away your own example.
And so Caesar utilized the same procedure. M. Aemilius Lepidus (later to be triumvir with Octavian and Antony), the praetor in 49, put forward the legislative measure – once again, proposed as a law rather than through the normal process – to make Caesar dictator for that year (Dio 41.36.1-3), with the same sweeping powers to legislate by fiat that Sulla had. One of the first things Caesar did was openly threaten the tribunes with violence if they interfered with him; as noted the tribune’s powers were not at the discretion of the dictator in the customary system and tribunes were held to be sacrosanct and thus legally immune to any kind of coercion by other magistrates, so this too represented a continuation of Sulla’s massive increase in the dictator’s absolute authority (App. BCiv 2.41, Plut. Caes. 35.6-11).
Caesar’s dictatorship, rather than initially being without time limit, was renewed, presumably every six months, from 49 through February 44, when Caesar had himself instead appointed dictator perpetuo rei publicae constieundae causa, “Dictator forever for the reformation of the Republic”, at this point (if not earlier) reusing Sulla’s made-up causa and now making explicit his intention to hold the office for life. He was assassinated a month later, on March 15, 44 BC, so perpetuo turned out to not be so perpetual.
As an aside, Julius Caesar is sometimes given a rosy glow in modern teaching materials, in part because he got such a glow from the ancient sources (one could hardly do otherwise writing under the reign of his grand-nephew, Augustus, who had him deified). That glow was often reinforced by (early) modern writers writing with one eye towards their monarch – Shakespeare, for instance. This may be a topic for another time, but I think a fair assessment of Caesar strips away most of this glow (especially his “man of the people” reputation), except for his reputation as a gifted general, which is beyond dispute. Julius Caesar’s career was a net negative for nearly everyone he encountered, with the lone exception of Augustus.

QotD: The basics of army logistics before railways
We’ve introduced this problem before but we should do so again in more depth. Logistics in modern armies is rather unlike logistics in pre-modern armies; to be exact the break-point here is the development of the railroad. Once armies can be supplied with railroads, their needs shift substantially. In particular, modern armies with rail (or later, truck and air) supply can receive massively more supplies over long distance than pre-railroad armies. That doesn’t make modern logistics trivial, rather armies “consumed” that additional supply by adopting material intensive modes of warfare: machine guns and artillery fire a lot of rounds that need to be shipped from factories to the front while tanks and trucks require a lot of fuel and spare parts. Basics like food and water were no less necessary but became a smaller share of much, much larger logistics chains that are dominated by ammunition and fuel.
But in the pre-railroad era (note: including the early gunpowder era well into the 1800s) that wasn’t the case. Soldiers could carry their own weapons and often their own ammunition (which in turn put significant limits on both). For handheld weapons, the difference gunpowder made here was fairly limited, since muskets were fairly slow firing and soldiers had to carry the ammunition they’d have for a battle in any event. The major difference with gunpowder came with artillery (that is, cannon), which needed the cannon, their powder and shot all moved. The result was a substantial expansion of the “siege train” of the army, which did not change the structure of logistics but did place new and heavy demands on it, because the animals and humans moving all of that needed to be fed. But overwhelming all of that was food and, if necessary, water.
Adult men need anywhere from 2,000 to 3,200 calories per day in order to support their activity; soldiers marching under heavy load will naturally tend towards the higher end of this range. Now, these requirements can be fudged; as John Landers notes, soldiers who are underfed do not immediately shut off. On the other hand, they cannot be ignored for long: no matter the morale an undernourished army will struggle to perform. Starvation is real and does not care how many reps you could do or how motivated you were when the campaign started (in practice, armies that are not fed sufficiently dissolve away as men desert rather than starve).
Different armies and different cultures will meet that nutritional demand in different ways, but staple grains (wheat, barley, corn, rice) dominate rations in part because they also dominated the diet of the peasantry (being the highest calories-per-acre-farmed-and-labor-added foods) and because they were easy to move and store. Fruits and vegetables were, by contrast, always subject to local availability, since without refrigeration they were difficult to keep or move; meat at least could be smoked, salted or made into jerky, but its expense made it an optional bonus to the diet rather than the core of it. So the diet here is mostly bread; many armies reliant on wheat and barley agriculture came up with a fairly similar idea here: a dense but simple flour-and-water (and maybe salt) biscuit or cracker which if kept dry could keep for long periods and be easy to move. The Romans called this buccelatum; today we refer to a very similar modern idea as “hardtack“. However, because these biscuits aren’t very tasty, for morale reasons armies try to acquire actual bread where possible.
In practice the combination of calorie demands with calorie-dense grain-based foods is going to mean that rations tend to cluster in terms of weight, even from different armies. Spartan rations on Sphacteria were two choenikes of barley alphita (a course barley flour) per man per day (Thuc. 4.16.1) which comes out to roughly 1.4kg; Spartan grain contributions to the syssitia (Plut. Lyc. 12.2) were 1 medimnos of barley alphita per month, which comes out to almost exactly 1kg per day (but supplemented with meat and such). Both Roth and Erdkamp (op. cit. for both) try to calculate the weight of Roman rations based on reported grain rations and interpolations for other foodstuffs; Roth suggests a range of 1.1-1.327kg (of which .85kg was grain or bread), while Erdkamp simply notes that they must have been somewhat more than the .85kg grain ration minimum.1 The Army of Flanders was given pan de munición (“munition” or “ration” bread) made of a mix of wheat and rye in loaves of standard size; the absolute minimum ration was 1.5lbs (.68kg) per day (Parker, op. cit. 136), somewhat less than the more logistically capable (as we’ll see) Roman legions, but in the ballpark, especially when we remember that soldiers in the Army of Flanders often supplemented that with purchased or pillaged food. Daily U.S. Army rations during the American Civil War were around 3lbs (1.36kg; statistic via Engels (op. cit.) who inexplicably thinks this is a useful reference for Macedonian rations), but some of the things included (particularly the 1.6oz of coffee) were hardly minimum necessities; the United States much like the Romans has a well-earned reputation for better than average rations, though this is admittedly a low bar.
So we can see a pretty tight grouping here around 1kg, especially when we account for some of these ration-packages being supplemented by irregular but meaningful amounts of other foods (especially in the case of the Army of Flanders, where we know this happened). There is some wiggle room here, of course; marching rations like hardtack are going to be lighter per-day than raw grains or good bread (or other, even tastier foods). But once meat, vegetables and fruits – and the diet must be at least sometimes supplemented with non-grain foods for nutritional reasons – are accounted for, you can see how the rule of thumb around 3lbs or 1.36kg forms out of the evidence. Soldiers also need around three liters of water (which is 3kg, God bless the metric system) per day but we are going to operate on the hopeful assumption that water is generally available on the route of our march. If it isn’t our daily load jumps from 1.36kg to 4.36kg and our operational range collapses into basically nothing; in practice this meant that if local water wasn’t available an army simply couldn’t go there.2
Marching loads vary by army and period but generally within a range of 40 to 55kg or so (60 at the absolute upper-end). As you may well imagine, convincing soldiers to carry heavier loads demands a greater degree of discipline and command control, so while a general may well want to push soldier’s marching load up, the soldiers will want to push it down (and of course overloading soldiers is going to eventually have a negative impact on marching speed and movement capabilities). But you may well be thinking that 40-55kg (which is 90-120lbs or so) sounds more than ample – that’s a lot of food!
Except of course they need to carry everything and weapons, armor and (for gunpowder armies) shot are heavy. Roman soldiers were and are famous for having marched heavy, carrying as much of their equipment and supplies as possible in their packs, which the Romans called the sarcina (we’ll see why this could improve an army’s capabilities). This practice is often attributed to Gaius Marius in the last decade of the second century (Plut. Marius 13.1) but care is necessary as this sort of “reform” was a trope of Roman generalship and is used of even earlier generals than Marius (e.g. Plut. Mor. 201BC on Scipio Aemilianus). Various estimates for the marching load of Roman troops exist but the best is probably Marcus Junkelmann’s physical reconstruction (in Die Legionen des Augustus (1986); highly recommended if you can read German; alas for the lack of an English translation!) which recreated all of the Roman kit and measured a marching load of 54.8kg (120.8lbs), with ~43 of the 54.8kg reserved for weapons, armor, entrenching kit and personal equipment, leaving just 11.8kg for food (about ten days worth). Other estimates are somewhat less, but never much less than 40kg for a Roman soldier’s equipment before rations, leaving precious little weight in which to fit a lot of food.
The same exercise can be run for almost any kind of infantryman: while their load is often heavy, after one accounts for weapons, armor and equipment (and for later armies, powder and shot) there is typically little space left for rations, usually amounting to not more than a week or two (ten days is a normal rule of thumb). Since the army obviously has more than two weeks of work to do (and remember it needs to be able to march back to wherever it started at the end), it is going to need to get a lot more food.

1. To be clear, we know with some certainty that Roman rations were supplemented, but not by how much. If you read much older scholarship, you will find the notion that Roman soldier’s diet lacked regular meat; both Erdkamp and Roth reject this view decisively and for good reason.
2. I may return to the logistics of water later, but some range can be extended here by taking advantage of the fact that pack animals, while they need a lot of water per day over a long period, can be marched short periods with basically no water and still function, whereas water deprived humans die very quickly. Consequently an army can do a low-water “lunge” over short distances by loading its pack animals with water, not watering them, having the soldiers drink the water and then abandoning the pack animals as they die (the water they carried having been consumed). This is, to say it least, a very expensive thing to do – animals are not cheap! – but there is some evidence the Romans did this, on this see G. Moss, “Watering the Roman Legion” M.A. Thesis, UNC Chapel Hill (2015).

QotD: Prosopography
In the History Biz, prosopography is the study of quasi-familial relationships, a kind of “collective biography”. It’s different from genealogy, which studies direct lineal descent — So-and-So begot Wossname, like in the Bible. Your classic prosopography is Beard’s Economic Interpretation of the Constitution, which you still see Leftards on the Internet hauling out all the time, though of course they don’t know where it comes from (or that modern historians, who are far more flamingly Leftist than Beard ever dreamed of being, consider it largely discredited).
Prosopography is vital in the study of Classical Antiquity, especially the Roman Republic. The Romans, as I’m sure you recall, practiced “patronage and clientage” — a man’s clients were often in a very real way more important than his biological family. Prove that Wossname was So-and-So’s client, and you know a lot about Wossname, even if you can’t find it in the archaeological record, and what you do know about him from the record takes on a whole new meaning. For instance, under Gaius Marius (et al.), the patron / client relationship got extended to the army — coteries of officers and NCOs personally loyal to their commanding general, not to the State — and there’s your Fall of the Roman Republic.
Kremlinology required something similar. Since the important levels of the Apparat all went to the same Higher Party Schools in Moscow, the fact that So-and-So was Wossname’s roommate for a few semesters was potentially of much greater importance than anything So-and-So did as the People’s Commissar of Whatever. He might’ve looked like a real up-and-comer based on his early promotion to a prestige post, but based on his prosopography an experience Kremlinologist might deduce that this was just horse-trading — someone high up in the Politburo owed Wossname’s father a favor for something back in the Great Patriotic War, and so this was payback; Wossname wasn’t going any higher than that.
It’s even more important in a completely ideologized society like the USSR. No Roman client would ever go so far as to openly stab his patron in the back — no one in his society would ever trust him again; he’d get shanked the very minute he donned the purple — but a Roman could have a change of heart. He might get religion, of either the philosophical (Epicureanism, Stoicism) or the actual cultic sort. This would significantly change the patron / client relationship. But in a society like the USSR — ostentatiously dedicated to the World Proletarian Revolution — ideology imposed some hard limits …

Sulla: bloodthirsty psycho or saviour of the Republic?
Adrian Goldsworthy. Historian and Novelist
Published 23 Oct 2024Today’s question asked about Lucius Cornelius Sulla, the first man to the march his legions against the city of Rome, starting the first — but far from the last — of Rome’s civil wars. He killed a lot of people, broke a lot of laws and conventions, but as dictator also introduced a very “conservative” programme of reforms. How should we judge Sulla, as a selfish, brutal murderer, or as a reluctant rebel and well-intentioned reformer?

QotD: Roman Republic versus Seleucid Empire – the Battle of Magnesia
Rome’s successes at sea in turn set conditions for the Roman invasion of Anatolia, which will lead to the decisive battle at Magnesia, but of course in the midst of our naval narrative, we rolled over into a new year, which means new consuls. The Senate extended Glabrio’s command in Greece to finish the war with the Aetolians, but the war against Antiochus was assigned to Lucius Cornelius Scipio, one of the year’s consuls and brother of Publius Cornelius Scipio Africanus, the victor over Hannibal at Zama (202). There’s an exciting bit of politics behind Scipio getting the assignment (including his famous brother promising to serve as one of his military tribunes), but in a sense that’s neither here nor there. As we’ve seen, Rome has no shortage of capable generals. From here on, if I say “Scipio”, I mean Lucius Cornelius Scipio; if I want his brother, I’ll say “Scipio Africanus”.
Scipio also brought fresh troops with him. The Senate authorized him to raise a supplementum (recruitment to fill out an army) of 3,000 Roman infantry, 100 Roman cavalry, 5,000 socii infantry and 200 socii cavalry (Livy 37.2.1) as well as authorizing him to carry the war into Asia (meaning Anatolia or Asia Minor) if he thought it wise – which of course he will. In addition to this, the two Scipios also called for volunteers from Scipio Africanus’ veterans and got 5,000 of them, a mix of Romans and socii (Livy 37.4.3), so all told Lucius Cornelius Scipio is crossing to Greece with reinforcements of some 13,000 infantry (including some battle-hardened veterans), 300 cavalry and one Publius Cornelius Scipio Africanus.1 That said, a significant portion of this force is going to end up left in Greece to handle garrison duty and the Aetolians. Antiochus III, for his part, spends this time raising forces for a major battle, while dispatching his son Seleucus (the future Seleucus IV, r. 187-175) to try to raid Pergamum, Rome’s key ally in the region.
Once the Romans arrive (and join up with Eumenes’ army), both sides maneuvered to try and get a battle on favorable terms. Antiochus III’s army was massive with lots of cavalry – 62,000 infantry and 12,000 cavalry, an army on the same general order of magnitude as the one that fought at Raphia – so he sought an open area, setting up his fortified camp near Magnesia, with fairly formidable defenses – a ditch with a double-rampart (Livy 37.37.9-11). Unsurprisingly, the Romans, with a significant, but smaller force, preferred a fight in more confined quarters and for several days the armies sat opposite each other with minor skirmishes (Livy 37.38).
The problem Scipio faced was a simple one: the year was coming to a close, which meant that soon new consuls would be elected and he could hardly count on his command being extended. Consequently, Scipio calls together his war council – what the Romans call a consilium – to ask what he should do if Antiochus III couldn’t be lured into battle on favorable terms. The answer he got back was to force a battle and so force a battle Scipio did, advancing forward onto the ground of Antiochus’ choosing, leading to the Battle of Magnesia.
We have two accounts of this battle which mostly match up, one in Livy (Livy 37.39-44) and another in Appian’s Syrian Wars (App. Syr. 30-36). Livy here is generally the better source and chances are both authors are relying substantially on Polybius (who would be an even better source), whose account of the battle is lost.
Antiochus III’s army was enormous, with a substantial superiority in cavalry. From left to right, according to Livy (Livy 37.40), Antiochus III deployed: Cyrtian slinger and Elymaean archers (4,000), then a unit of caetrati (4,000; probably light infantry peltasts), then the contingent of Tralli (1,500; light infantry auxiliaries from Anatolia), then Carian and Cilicians equipped like Cretans (1,500; light archer infantry), then the Neo-Cretans (1,000; light archer infantry), then the Galatian cavalry (2,500; mailed shock cavalry), then a unit of Tarantine cavalry (number unclear, probably 500; Greek light cavalry), a part of the “royal squadron” of cavalry (1,000; Macedonian shock cavalry), then the ultra-heavy cataphract cavalry (3,000), supported by a mixed component of auxiliaries (2,700; medium thureophoroi infantry?) along with his scythed chariots and Arab camel troops.
That gets us to the central component of the line (still reading left to right): Cappadocians (2,000) who Livy notes were similarly armed to the Galatian infantry (1,500, unarmored, La Tène infantry kit, so “mediums”) who come next. Then the main force of the phalanx, 16,000 strong with 22 elephants. The phalanx was formed 32 ranks deep, with the intervals between the regiments covered by the elephants deployed in pairs, creating an articulated or enallax phalanx like Pyrrhus had, but using elephants rather than infantry to cover the “hinges”. This may in fact, rather than being a single phalanx 32 men deep be a “double” phalanx (one deployed behind the other) like we saw at Sellasia. Then on the right of the phalanx was another force of 1,500 Galatian infantry. Oddly missing here is the main contingent of the elite Silver Shields (the Argyraspides); some scholars2 note that a contingent of them 10,000 strong would make Livy’s total strength numbers and component numbers match up and he has just forgotten them in the main line. We might expect them to be deployed to the right of the main phalanx (where Livy will put the infantry Royal Cohort (regia cohors), confusing a subunit of the argyraspides with the larger whole unit. Michael Taylor in a forthcoming work3 has suggested they may also have been deployed behind the cavalry we’re about to get to or otherwise to their right.
That gets us now to the right wing (still moving left to right; you begin to realize how damn big this army is), we have more cataphracts (3,000, armored shock cavalry), the elite cavalry agema (1,000; elite Mede/Persian cavalry, probably shock), then Dahae horse archers (1,200; Steppe horse archers), then Cretan and Trallian light infantry (3,000), then some Mysian Archers (2,500) and finally another contingent of Cyrtian slinger and Elymaean archers (4,000).
This is, obviously, a really big army. But notice that a lot of its strength is in light infantry: combining the various archers, slingers and general light infantry (excluding troops we suspect to be “mediums”) we come to something like 21,500 lights, plus another 7,700 “medium” infantry and then 26,000 heavy infantry (accounting for the missing argyraspides). That’s 55,200 total, but Livy reports a total strength for the army of 62,000; it’s possible the missing remainder were troops kept back to defend the camp, in which case they too are likely light infantry. A Roman army’s infantry contingent is around 28% “lights” (the velites), who do not occupy any space in the main battle line. Antiochus’ infantry contingent, while massive, is 39% “lights” (and another 14% “mediums”), some of which do seem to occupy actual space in the battle line.
Of course Antiochus also has a massive amount of cavalry ranging from ultra-heavy cataphracts to light but highly skilled horse archers and massive cavalry superiority covereth a multitude of sins.
But the second problem with this gigantic army is one that – again, in a forthcoming work – Michael Taylor has pointed out. The physical space of the battlefield at Magnesia is not big enough to deploy the whole thing […]
Now Livy specifies that the flanks of Antiochus’ army curve forward, describing them as “horns” (cornu) rather than “wings” (alae) and noting they were “a little bit advanced” (paulum producto), which may be an effort to get more of this massive army actually into the fight […]. So while this army is large, it’s also unwieldy and difficult to bring properly into action and it’s not at all clear from either Livy or Appian that the whole army actually engaged – substantial portions of that gigantic mass of light infantry on the wings just seem to dissolve away once the battle begins, perhaps never getting into the fight in the first place.
The Roman force was deployed in its typical formation, with the three lines of the triplex acies and the socii flanking the legions (Livy 37.39.7-8), with the combined Roman and socii force being roughly 20,000 strong (the legions and alae being somewhat over-strength). In addition Eumenes, King of Pergamum was present and the Romans put his force on their right to cover the open flank, while he anchored his left flank on the Phrygios River. Eumenes’ wing consisted of 3,000 Achaeans (of the Achaean League) that Livy describes as caetrati and Appian describes as peltasts (so, lights), plus nearly all of Scipio’s cavalry: Eumenes’ cavalry guard of 800, plus another 2,200 Roman and socii cavalry, and than some auxiliary Cretan and Trallian light infantry, 500 each. Thinking his left wing, anchored on the river, relatively safe, Scipio posted only four turmae of cavalry there (120 cavalry). He also had a force of Macedonians and Thracians mixed together – so these are probably “medium” infantry – who had come as volunteers, who he posts to guard the camp rather than in the main battleline. I always find this striking, because I think a Hellenistic army would have put these guys in the front line, but a Roman commander looks at them and thinks “camp guards”. The Romans also had some war elephants, sixteen of them, but Scipio assesses that North African elephants won’t stand up to the larger Indian elephants of the Seleucids (which is true, they won’t) and so he puts them in reserve behind his lines rather than out front where they’d just be driven back into him. All told then, the Roman force is around 26,000 infantry and 3,000 cavalry – badly outnumbered by Antiochus, but of a relatively higher average quality and a bit more capable of actually fitting its entire combat power into the space.
The Battle
Because the armies are so large, much like as happened at Raphia, the battle that results is almost three battles running in parallel: the two wings and the center. Antiochus III commanded from his right wing, where – contrary to the expectations of Scipio who thought the river would secure his flank there – he intended his main attack. His son Seleucus commanded the left. Livy reports a light rain which interfered with both with visibility and some of Antiochus’ light troops’ weapons, as their bows and slings reacted poorly to the moisture (as composite bows will sometimes do; Livy 37.41.3-4, note also App. Syr. 33).Antiochus opens the battle on his left with his scythed chariots, a novel “gimmick” weapon (heavy chariots with blades all over them, used to shock infantry out of position). This may have been a nasty surprise for the Romans, but given the dispositions of the army, it was Eumenes, not Scipio who faces the chariots and as Livy notes, Eumenes was well aware how to fight them (Livy 37.41.9), using his light troops – those Cretan archers and Trallian javelin-troops. Deployed in loose order, they were able to move aside to avoid the chariots better than heavy infantry in close-order (similar tactics are used against elephants) and could with their missiles strike at chariot drivers and horses at range (Livy 37.41.10-12). Turning back this initial attack seems to have badly undermined the morale of the Seleucid left-wing, parts of which fled, creating a gap between the extreme left-wing and the heavy cavalry contingent. Eumenes then, with the Roman cavalry, promptly hammered the disordered line, hitting first the camel troops, then in the confusion quickly overwhelming the rest of the cavalry, including the cataphracts, leading Antiochus’ left wing to almost totally collapse, isolating the phalanx in the center. It’s not clear what the large mass of light infantry on the extreme edge of the battlefield was doing.
Meanwhile on the other side of the battle, where Scipio had figured a light screen of 120 equites would be enough to hold the end of the line, Antiochus delivered is cavalry hammer-blow successfully. Obnoxiously, both of our sources are a lot less interested in describing how he does this (Livy 37.42.7-8 and App. Syr. 34), which is frustrating because it is a bit hard to make sense of how it turns out. On the one hand, the constricted battlefield will have meant that, regardless of how they were positioned, those argyraspides are going to end up following Antiochus’ big cavalry hammer on the (Seleucid) right. They then overwhelm the cavalry and put them to flight and then push the infantry of that wing (left ala of socii and evidently a good portion of the legion next to it) back to the Roman camp.
On the other hand, the Roman infantry line reaches its camp apparently in good order or something close to it. Marcus Aemilius, the tribune put in charge of the camp is able to rush out, reconstitute the infantry force and, along with the camp-guard, halt Antiochus’ advance. The thing is, infantry when broken by cavalry usually cannot reform like that, but the distance covered, while relatively short, also seems a bit too long for the standard legionary hastati-to-principes-to-triarii retrograde. Our sources (also including a passage of Justin, a much later source, 31.8.6) vary on exactly how precipitous the flight was and it is possible that it proceeded differently at different points, with some maniples collapsing and others making an orderly retrograde. In any case, it’s clear that the Roman left wing stabilized itself outside of the Roman camp, much to Antiochus’ dismay. Eumenes, having at this point realized both that he was winning on his flank and that the other flank was in trouble dispatched his brother Attalus with 200 cavalry to go aid the ailing Roman left wing; the arrival of these fellows seem to have caused panic and Antiochus at this point begins retreating.
Meanwhile, of course, there is the heavy infantry engagement at the center. Pressured and without flanking support, Appian reports that the Seleucid phalanx first admitted what light infantry remained and then formed square, presenting their pikes tetragonos, “on all four sides” (App. Syr. 35), a formation known as a plinthion in some Greek tactical manuals. Forming this way under pressure on a chaotic battlefield is frankly impressive (though if they were formed as a double-phalanx rather than a double-thick single-phalanx, that would have made it easier) and a reminder that the core of Antiochus’ army was quite capable. Unable in this formation to charge, the phalanx was showered with Roman pila and skirmished by Eumenes’ lighter cavalry; the Romans seem to have disposed of Antiochus’ elephants with relative ease – the Punic Wars had left the Romans very experienced at dealing with elephants (Livy 37.42.4-5). Appian notes that some of the elephants, driven back by the legion and maddened disrupted the Seleucid square, at which point the phalanx at last collapsed (App. Syr. 35); Livy has the collapse happen much faster, but Appian’s narrative here seems more plausible.
What was left of Antiochus’ army now fled to their camp – not far off, just like the Roman one – leading to a sharp battle at the camp which Livy describes as ingens et maior prope quam in acie cades, “a huge slaughter, almost greater than that in the battle” (Livy 37.43.10), with stiff resistance at the camp’s gates and walls holding up the Romans before they eventually broke through and butchered the survivors. Livy reports that of Antiochus’ forces, 50,000 infantry and 3,000 cavalry were killed, another 1,500 captured; these seem really high as figures go, but Appian reports almost the exact same. Interesting, Livy doesn’t report the figure in his own right or attribute it to Polybius but instead simply notes “it is said that”, suggesting he may not be fully confident of the number either. Taylor supposes, reasonably I think, that this oversized figure may also count men who fled from the battlefield, reflecting instead that once Antiochus III could actually reconstitute his army, he had about 19,000 men, most of the rest having fled.4 Either way, the resulting peace makes clear that the Seleucid army was shattered beyond immediate repair.
Roman losses, by contrast, were shockingly light. Livy reports 300 infantry lost, 24 Roman cavalry and 25 out of Eumenes’ force; Appian adds that the 300 infantry were “from the city” – meaning Roman citizens – so some socii casualties have evidently been left out (but he trims Eumenes’ losses down to just fifteen cavalry) (Livy 37.44.2-3; App. Syr. 36). Livy in addition notes that many Romans were wounded in addition to the 300 killed. This is an odd quirk of Livy’s casualty reports for Roman armies against Hellenistic armies and I suspect it reflects the relatively high effectiveness of Roman body armor, by this point increasingly dominated by the mail lorica hamata: good armor converts lethal blows into survivable wounds.5 It also fits into a broader pattern we’ve seen: Hellenistic armies that face Roman armies always take heavy casualties, winning or losing, but when Roman armies win they tend to win lopsidedly. It is a trend that will continue.
So why Roman victory at Magnesia? It is certainly not the case that the Romans had the advantage of rough terrain in the battle: the battlefield here is flat and fairly open. It should have been ideal terrain for a Hellenistic army.
A good deal of the credit has to go to Eumenes, which makes the battle a bit hard to extrapolate from. It certainly seems like Eumenes’ quick thinking to disperse the Seleucid chariots and then immediately follow up with his own charge was decisive on his flank, though not quite battle winning. Eumenes’ forces, after all, lacked the punch to disperse the heavier phalanx, which did not panic when its wing collapsed. Instead, the Seleucid phalanx, pinned into a stationary, defensive position by Eumenes’ encircling cavalry, appears to have been disassembled primary by the Roman heavy infantry, peppering it with pila before inducing panic into the elephants. It turns out that Samnites make better “glue” for an articulated phalanx than elephants, because they are less likely to panic.
Meanwhile on the Seleucid right (the Roman left), the flexible and modular nature of the legion seems to have been a major factor. Antiochus clearly broke through the Roman line at points, but with the Roman legion’s plethora of officers (centurions, military tribunes, praefecti) and with each maniple having its own set of standards to rally around, it seems like the legion and its socii ala managed to hold together and eventually drive Antiochus off, despite being pressured. That, in and of itself, is impressive: it is the thing the Seleucid center fails to do, after all.

The Third Triumvirate?
On the social media platform formerly known as Twitter, John Carter posted an amusing thread (unrolled here courtesy of the @threadreaderapp):
Trump, Musk, Vance: the new triumvirate, bringing a window of stability to the troubled Republic.
Trump: the old warhorse, beloved of the people, a part of the establishment but with an uneasy relationship to it. Trump is Pompey.
Musk: the richest man in the world. Musk is Crassus.
Vance: the charismatic young upstart. Vance is Caesar.
So how does this play out?
Musk’s ambition is to go to Mars, just as Crassus wanted to conquer Parthia. Musk harnesses his wealth, launches the expedition to great fanfare. Things go horribly wrong after their arrival. Contact with the colony is lost. Musk’s grave is never found.
At the head of a private military corporation equipped with letters of marque, Vance is sent into the badlands of South America to crush the cartels and secure the Panama Canal. The war takes longer than expected. By the end of it, Vance hasn’t merely crushed the cartels – he’s conquered the entirety of Central America.
At home, Vance is beset by his enemies in the Senate, who mistrust his ambitions and intentions. It is whispered that he wishes to make himself king.
Vance’s enemies whisper in Trump’s ears. Were you not the one who built the wall? If Vance brings the Central American republics into the Union, what then of immigration? Of your life’s work? Vance will destroy it all.
And do the people, after all, not love you first and most? Are you not their hero? Why then should you fear this upstart?
With Trump’s blessing, Vance is recalled by the Senate, to face charges of corruption.
But throughout this time Vance has been building auctoritas with the people, going directly to them with his poasts, showing them his victories and their fruits. The people have come to love him more than they love Trump — for he has sent great wealth back to them, and crushed their enemies abroad.
And so the fateful day comes in which Vance returns, as summoned … but he does not demobilize his mercenary army when it crosses the Rio Grande. His forces — which now include former cartel soldiers, some of whom he has won to his side — drive straight to Washington in a blitzkrieg attack.
Washington empties out in panic.
Trump and the Senate flee to New York City, where they rally their forces. There are still many who are loyal to Trump, particularly within the military … but it turns out that Trump’s base is much older than Vance’s … and there are many, more than expected, who declare for Vance.
And so the Union cracks apart into the Civil War that was deferred when the triumvirate first seized power, so many years ago.
But this is not first and foremost a war of ideology, as it would have been — a showdown between right and left.
It is a war of personalities and personal loyalty, a war to determine a single question: who is to be king?
Obviously none of this is going to happen. History never repeats itself so precisely.
But it’s fun to think about Vance rampaging around Central America at the head of a PMC.

QotD: Decisive factors in the Roman victory over the Seleucids
Zooming out even further, why Roman victory in the Roman-Seleucid War? I think there are a few clear factors here.
Ironically for a post covering land battles, the most important factor may be naval: Rome’s superior naval resources (and better naval allies), which gave the Romans an enormous operational advantage against Antiochus. In the initial phase, the Romans could get more troops to Greece than the king could, while further on, Roman naval supremacy allowed Roman armies to operate in Anatolia in force (while Antiochus, even had he won in Greece, had no hope of operating in Italy). Neutralizing Antiochus’ navy both opened up options for the Romans and closed down options for Antiochus, setting the conditions for Roman victory. It would have also neutered any Roman defeat. If Antiochus wins at Magnesia, he cannot then immediately go on the offensive, after all: he has merely bought perhaps a year or two of time to rebuild his navy and try to contest the Aegean again. Given the astounding naval mobilizations Rome had shown itself capable of in the third century, one cannot imagine Antiochus was likely to win that contest.
Meanwhile, the Romans had better allies, in part as a consequence of the Romans being better at getting allies. The Romans benefit substantially from allied Achaean, Pergamese and Rhodian ships and troops, as well as support from the now-humbled Philip V of Macedon and even supplies and auxiliaries from Numidia and Carthage. Alliance-management is a fairly consistent Roman strength and it shows here. It certainly seems to help that Roman protestations that they had little interest in a permanent presence in Greece seem to have been somewhat true; Rome won’t set up a permanent provincia in Macedonia until 146 (though the Romans do expect their influence to predominate before then). By contrast, Antiochus III, clearly bent on rebuilding Alexander’s empire, was a more obvious threat to the long-term independence and autonomy of Greek states like the Pergamum or Rhodes.
Finally, there is the remarkable Seleucid glass jaw. The Romans, after all, sustained a defeat very much like Magnesia against Hannibal in 216 (the Battle of Cannae) and kept fighting. By contrast, Antiochus is forced into a humiliating peace after Magnesia, in which he cedes all of Anatolia, gives up any kind of navy and is forced to pay a crippling financial indemnity which will fatally undermine the reign of his successor and son Seleucus IV (leading to his assassination in 175, leading to yet further Seleucid weakness). Part of this glass jaw may have been political: after Magnesia, Antiochus’ own aristocrats seem pretty well done with their king’s adventurism against Rome.
But at the same time, some of it was clearly military. Antiochus didn’t have a second army to fall back on and Magnesia represented essentially a peak “all-call” Seleucid mobilization. A similar defeat at Raphia had forced a similarly unfavorable peace earlier in his reign, after all. Part of the problem, I would argue, is that the Seleucids needed their army for more than just war: they needed it to enforce taxation and tribute on their own recalcitrant subjects. As a result, no Seleucid king could afford to “go for broke” the way the Roman Republic could, nor could the Seleucids ever fully mobilize the massive population of their realm. The very nature of the Hellenistic kingdom’s ethnic hierarchy made fully tapping the potential resources of the kingdom impossible.
As a result, while Antiochus III was not an incompetent general, he ruled a deceptively weak giant. Massive revenues were offset by equally massive security obligations and the Seleucids seem to have been perenially cash strapped (with a nasty habit of looting temples to make up for it). The very nature of the Seleucid Empire – like the Ptolemaic one – as an ethnic empire where Macedonians ruled and non-Macedonians were ruled kept Antiochus from being able to fully mobilize his subjects. It may also explain why so many of those light infantry auxiliaries seem to have run off without much of a fight. Eumenes and his Pergamese troops fought for their independence, the Romans for the greater glory of Rome and the socii for their own status and loot within the Roman system, but what could Antiochus offer a subjected Carian or Cilician except a paycheck and a future of continued subjugation? That’s not much to die for.

QotD: The Roman Republic versus the heirs of Alexander the Great
Last time, we finished our look at the third-century successes of the phalanx with the career of Pyrrhus of Epirus, concluding that even when handled very well with a very capable body of troops, Hellenistic armies struggled to achieve the kind of decisive victories they needed against the Romans to achieve strategic objectives. Instead, Pyrrhus was able to achieve a set of indecisive victories (and a draw), which was simply not anywhere close to enough in view of the tremendous strategic depth of Rome.
Well, I hope you got your fill of Hellenistic armies winning battles because it is all downhill from here (even when we’re fighting uphill). For the first half of the second century, from 200 to 168, the Romans achieve an astounding series of lopsided victories against both (Antigonid) Macedonian and Seleucid Hellenistic armies, while simultaneously reducing several other major players (Pergamon, Egypt) to client states. And unlike Pyrrhus, the Romans are in a position to “convert” on each victory, successfully achieving their strategic objectives. It was this string of victories, so shocking in the Greek world, that prompted Polybius to write his own history, covering the period from 264 to 146 to try to explain what the heck happened (much of that history is lost, but Polybius opens by suggesting that anyone paying attention to the First Punic War (264-241) ought to have seen this coming).
That said, this series of victories is complex. Of the five major engagements (The River Aous, Cynoscephalae, Thermopylae, Magnesia, and Pydna) Rome commandingly wins all of them, but each battle is strange in its own way. So we’re going to look at each battle and also take a chance to lay out a bit of the broader campaigns, asking at each stage why does Rome win here? Both in the tactical sense (why do they win the battle) and also in the strategic sense (why do they win the war).
We’re going to start with the war that brought Rome truly into the political battle royale of the Eastern Mediterranean, the Second Macedonian War (200-196). Rome was acting, in essence, as an interloper in long-running conflicts between the various successor dynasties of Alexander the Great as well as smaller Greek states caught in the middle of these larger brawling empires. Briefly, the major players are the Ptolemaic Dynasty, in Egypt (the richest state), the Seleucid Dynasty out of Syria and Mesopotamia (the largest state) and the Antigonid Kingdom in Macedonia (the smallest and weakest state, but punching above its weight with the best man-for-man army). The minor but significant players are the Attalid dynasty in Pergamon, a mid-sized Hellenistic power trapped between the ambitions of the big players, two broad alliances of Greek poleis in the Greek mainland the Aetolian and Achaean Leagues, and finally a few freewheeling poleis, notably Athens and Rhodes. The large states are trying to dominate the system, the small states trying to retain their independence and everyone is about to get rolled by the Romans.

QotD: Did the customary Dictatorship work in the Roman Republic?
Of the roughly 85 dictatorships in the “customary” period from 501 to 202, 0% of them seized control of the state, led or participated in a major violent insurrection. […]
How could an office with such extensive powers be so apparently stable? Dictators under the customary system simply lacked the tools necessary to overthrow the state even if they wanted to. As noted, all of the other magistrates remained in office and while they were notionally subordinate to the dictator, they didn’t need to be cooperative (and surely wouldn’t be if a dictator announced he was staying on after the end of his term). Dictators couldn’t legislate on their own and so couldn’t alter the constitutional structure of the Republic itself. Moreover, one key magistracy, that of the tribunes of the plebs, remained distinctly outside of the dictator’s power and by the third century were equipped with a range of highly disruptive powers and a mandate to protect the interests of the Roman people which would justify them blocking a dictator’s efforts to seize power.
The dictator’s command of the army was likewise not an effective tool to dominate the state. The Roman army of the early and middle republics was a citizen militia, so the dictator would need to convince the Roman voting assemblies to abolish themselves. Moreover, with a mere six-month command, no dictator was likely to remain in command of his army long enough to foster the kind of iron-clad loyalty he would need to then direct that army against the rest of the state.
In terms of allowing rapid and unified response to a fast-moving crisis, the dictatorship also seems generally to have worked well, allowing the Romans to temporarily suspend whatever political gridlock might exist, but in a context that rarely allowed for one side to win the gridlock by suspending it, since the causa [the specific, named problem that triggered the appointment] of the dictator was limited and generally externally directed. In cases where a dictator was appointed to deal with internal dissent, they often still had to compromise in the face of popular discontent because they lacked the tools to coerce the political system; P. Manlius Capitolinus (dict. 368) had to push a major compromise in order to get the plebs back on board after the previous dictator, M. Furius Camillus, had attempted to strong-arm the issue. On the flipside, Manius Valerius (dict. 494), being appointed dictator in 494 to deal with a military crisis and a successio plebis, defeated the external enemy and then suggested the senate compromise internally, which it refused to do. He simply resigned his dictatorship, to the acclaim of the people.
While the powers of the dictator are often stated as being “absolute” or “extreme” (and were, compared to the power of a consul), the customary dictatorship was essentially just a unitary executive, something that quite a lot of modern governments have. Customary Roman dictators were, if anything, less powerful than most modern Prime Ministers or the modern President of the United States. Like many ancient civic governments, the Roman Republic was constructed with a lot of worry about monarchy and thus tended to keep its offices short in duration and institutionally weak and the dictatorship was no exception.

“Like Sulla, [Trump]’s been taking names, and he has a list”

So-called “Sulla” (probably from the time of Augustus) after a portrait of an important Roman from the 2nd century BC.
From the Glyptothek collection via Wikimedia Commons.
The comparison of Trump to the man who prefigured Julius Caesar in the final years of the Roman Republic is, we should all passionately hope, more rhetorical than realistic. Sulla came to power in Rome after being, in his view, illegally removed from his rightful position, and he came wading through the blood of his enemies. He then created a brand new position for himself, using the old and disused title of “dictator”, but piling on far more power than any earlier dictator had held (the irregular election was held in hearing distance of where Sulla’s army was busy executing many of his captured enemies). He used his power to reconfigure and codify the rules by which the Republic was run, to “restore the Republic” to what he imagined was a purer, better nation. He set a precedent that would be followed a generation later by Julius Caesar and the end of the Republic was clearly in sight.
Trump has come again to power, from which he believes he was illegally removed, although he has not been wading through the blood of his enemies. He has been using the powers of his position very actively, but thus far seems to be staying within the bounds of the Constitution (mostly). On his Substack, Glenn Reynolds says that the second Trump presidency will be much worse for his political opponents than if he’d won his second term in 2020, and I think that’s the right analysis:
Well, if you follow me here, you probably don’t need to be told how fast Trump is moving. But I have a few other thoughts here that didn’t fit the column. The main point is that the Democrats’ over-the-top rule-breaking, norm-busting attacks on Trump have backfired bigly. I like to use the Tolkien quote, “oft evil will shall evil mar”, and that happened here for sure.
A second consecutive Trump term would have been better, from my perspective, than Biden’s sham administration, obviously. But it certainly would have been better for the Democrats than this second non-consecutive term. Trump spent the past four years not only planning his comeback, but planning what he would do after his comeback.
In his first term he was too busy running to plan, and he was naïve about how Washington and the federal government – and the Republican Party – actually work. Not so much anymore. I’ve seen people – to continue the Tolkien reference – compare him to Gandalf the White coming back after battling the Balrog, and that’s not a bad analogy.
Then there’s this one, which pretty much sums up what I’m saying here. Like Sulla, he’s been taking names, and he has a list.
And there’s this:
It really is. Trump could get carried away with this stuff at some point, but at present he seems to be settling all family business in a very measured way. Where the opening months of the first Trump Administration were confused – Omarosa in the White House? – this time around he’s realized that personnel is policy, and he’s clearly done a lot of thinking about who his personnel will be. And it’s no coincidence that he’s put a lot of people who were victims of various government agencies in charge of those same agencies. Not much danger of them going native, I think.
A second consecutive Trump term would have delayed the advance of the left/Democrat agenda, and pushed it back in some minor ways, but would probably have ultimately been no more than a bump in the road for that agenda. This Trump term will likely burn it down.
