Polybius: The Histories. Robin Waterfield translation. Oxford: Oxford University Press, 2010.
A Greek from Megalopolis, Arcadia, researching, thinking, writing in Rome during the second century BC, Polybius acknowledges that all preceding historians have held that “knowledge of past events” provides an excellent “corrective of human behavior” because there is no better way “to prepare and train oneself for political life” than the study of those events and because “there is no more comprehensible and comprehensive teacher of the ability to endure with courage the vicissitudes of Fortune than a record of others’ catastrophes” (I.i). Among the possible topics for such study, Rome ranks at the top—specifically, Rome under the republican regime. “Is there anyone on earth who is so narrow-minded or uninquisitive that he could fail to want to know how and thanks to what regime almost the entire known world was conquered and brought under a single empire, the empire of the Romans, in less than fifty-three years [that is, between 220 and 167 BC]—an unprecedented event?” (I.i). By the known world, Polybius means those regions surrounding the Mediterranean Sea, extending from the Persians in the east to the Iberians in the west, from the Byzantines and Gauls in the north to the Egyptians and Carthaginians in the south. Greeks were of course aware of regions farther afield (Alexander had reached India two centuries before Polybius died) but the Mediterranean was known familiarly by trading, soldiering, and diplomacy.
The Romans “have made themselves masters of almost the entire known world, not just some bits of it, and have left such a colossal empire that no one alive today can resist it and no one in the future will be able to overcome it. My work will make it possible to understand more clearly how the empire was gained, and no reader will be left in doubt about the many important benefits to be gained from reading political history” (I.ii) Political history: as a student of Aristotle, Polybius knows that political life centers on regimes, and that regimes consist of rulers, ruling institutions, the purposes set by the rulers acting through those institutions, and the ways of life fostered by the rulers and institutions in pursuit of those purposes. This explains a feature of Polybius’ history which may seem odd to modern readers. After the first five books, the first “pentad,” he offers a book describing the Roman regime itself—an exercise in political science, not history. Polybius’ history is indeed the story of the Roman regime in motion; but to help his reader understand the regime’s structure he needs to bring the action to a rest, to look at its form, its animating principles, and the human ‘type’ it brings forth. Only an account of Rome’s regime can clarify Rome’s actions and explain their success. As Aristotle teaches, politic is architectonic.
Persia, Sparta, and Macedon had built empires before Rome. None of them was as extensive. The extensiveness of Rome requires an equally wide-ranging history—what we would now call a ‘geopolitical’ account of Rome’s conquests. “Before this time, things happened in the world pretty much in a sporadic fashion, because every incident was specific, from start to finish, to the part of the world where it happened. But ever since [the time of “the so-called Social War in Greece” beginning in 220] history has resembled a body, in the sense that incidents in Italy and Libya and Asia and Greece are all interconnected, and everything tends towards a single outcome” (I.iii). “The distinctive feature of my work (which is at the same time the most remarkable feature of our epoch)” is precisely that “Fortune has turned almost all the events of the known world in a single direction and has forced everything to tend towards the same goal.” Polybius intends to show how Fortune accomplished this; “no one else in our times has attempted to write [such] a universal history,” centered on “the finest thing Fortune has ever achieved, and the one from which we can learn most” (I.iv). Unlike many modern geopolitical writers, however, Polybius does not explain geopolitics in terms of ‘power,’ simply, as if ‘states’ resembled billiard balls differing only in size, density, and velocity. He understands geopolitics in terms of rival regimes, each with its own ruling persons, complex structure, purposes, way of life. He describes not only the Roman regime but the regimes of Carthage, Macedon, the Greeks, Egypt, the Gauls. The first two books of the history will therefore treat particularly of the intentions of the Roman rulers and the point at which they decided to found an empire, not only of their forces and resources (which all geopolitical writers discuss).
To understanding the starting point, the archē, of the Roman empire, Polybius reaches back several decades the final consolidation of Rome’s rule over Italy. In the wars leading up to that, “their trials of strength against the Samnites and Celts had already made them true athletes of warfare” (I.vi). This is the first suggestion that the Roman regime was a specific kind of republic, a military republic—as contrasted with the largely commercial, seafaring republics of Carthage and much later, of Great Britain and the United States. By 280 BC, Romans “for the first time set out against the rest of Italy, treating it not as foreign soil, but for the most part as if it were already theirs and belonged to them” (I.vi). The occasion was the invasion of Italy by Pyrrhus, king of the Greek polis, Epirus, who was called in by the people of Tarentum, who were frightened of the Romans but lacked the strength to fight them alone; the people of Rhegium, themselves threatened both by Pyrrhus’ forces and the Carthaginian navy, in turn called in the Romans to defend them. Roman troops betrayed Rhegium, seized it, but were eventually killed or taken prisoner by a subsequent Roman expeditionary force; the Romans, enraged at the betrayal of an ally by their own men, “lost no time in returning the land and the city to the people of Rhegium” (I.vii). As for Pyrrhus, he defeated the Romans in several battles but, famously, incurred such heavy losses that he was forced to return to Greece. Rome’s military republic thus exhibited resiliency and honor, keeping its army under civilian rule while encouraging the military spirit amongst its citizens while uniting Italy under its hegemony.
That left the Carthaginians as their main rival in the western Mediterranean. The Romans saw that “the Carthaginians had subjugated not only Libya but much of Iberia too, as well as controlling all the islands in the Sardinian and Tyrrhenian seas, and they were worried that, if the Carthaginians came to dominate Sicily too, they would become too much of a threat and a danger on their borders, since they would surround the Romans and threaten Italy on all sides” (I.x). Although the aristocratic Senate was cautious, the people wanted to defend the Sicilian city of Messana from the Carthaginians, motivated not only by geopolitical concerns but by “the certainty of significant profit for each and every one of them” if Roman rule over Sicily could be secured (I.xi). “That was the first time an armed force of Romans left Italy by sea” (I.xii), touching off the first war with Carthage. Just as in the United States, debate in the 1890s centered on the question of acquiring an ‘overseas empire’—as distinguished from the Jeffersonian ’empire of liberty’ extending across North America, which preoccupied American statesmen from the founding until 1890, a series of land purchases and conquests that had come to be described as the nation’s ‘Manifest Destiny’—so for Rome the advance to the neighboring island, Sicily, into the Mediterranean itself, was understood as a major step towards a ‘real’ empire. In this first imperial venture, the Romans won, defeating the Carthaginians and securing a foothold in Sicily. Their position strengthened when the Syracusan monarch, Hieron, chose to side with the Romans, becoming the Romans’ “source of provisions in times of emergency” and enjoying, in return, “safety for the rest of his life” (I.xvi). As for the Romans, in the ensuing conflicts with Carthage, they “were saved…by the excellence of their institution,” which (for example) habituated their soldiers to stand fast at their posts during a surprise raid by the Carthaginians (I.xvii).
The Romans did well in the Sicilian land war, soon capturing the Carthaginian stronghold at Acragus. But “as long as the Carthaginians had undisputed control of the sea, the outcome of the war hung in the balance,” with coastal towns especially inclined to switch allegiance as easily as shifts in the sea breeze (I.xx). Therefore, “the Romans committed themselves to taking the sea along with the Carthaginians,” in the hope not only of defending their own coast against enemy raids but of taking the war to Libya (I.xx). “Their shipwrights had no experience at all” in building ships “but this is exactly what reveals, more clearly than anything else, the scope and daring inherent in the Romans’ decision”—a daring bred into them, as it were, by the military ethos of their form of republicanism (I.xx). By the year 260, having built a fleet modeled on a captured Carthaginian vessel, they were launching their own raids on enemy territory; with their own technical innovation the ‘raven,’ which enabled their men to board rival ships easily, they won a number of their early encounters with the far more experienced sailors of Carthage.
A couple of years later, they mounted a serious naval offensive, “want[ing] the Carthaginians to feel that their very existence and their homeland were at risk”—the “last thing the Carthaginians wanted, because they were aware that Libya was vulnerable to an offensive and that any invader would easily subjugate the entire population there” (I.xxvi). They made an unsuccessful attempt to intercept the Roman fleet at sea; the Romans went on to seize one of their coastal cities. Desperate, the Carthaginians appealed to the Spartans, who sent an experienced general to their aid; the Spartans had no interest in seeing Rome continue its expansion. With his advice and training, the Carthaginians defeated the invaders, capturing their general.
“There are a number of lessons to be learnt here, by any man of discernment, that should help him improve his life” (I.xxxv). First, “Regulus’ ruin brought home to everyone at the time in the most stark manner the advisability of distrusting Fortune, especially when things are going well” (I.xxxv). Second, in dealing with Fortune (as Euripides wrote), “A wise plan is stronger than many hands”: “just one man,” the Spartan general, Xanthippus, “one intellect, overcame a host that had seemed invincible and irresistible, revived a state that had plainly hit rock bottom, and alleviated the despair that had gripped its armed force” (I.xxxv). Third, it’s better to learn such things from reading a judicious historian than from the school of hard knocks; as Polybius drily puts it, “opportunities for changing one’s life for the better are afforded by both one’s own setbacks and those of others, and while learning from personal disasters drives the lesson home most forcefully, learning from others’ afflictions is less painful” (I.xxxv). “And so we see that there is no teacher better at preparing one for real life than the experience of reading political history, because only political history delivers, without pain, the ability to judge the better course of action, whatever the occasion or the situation” (I.xxxv).
The Romans evacuated their troops but the returning fleet was destroyed by a powerful storm along the Sicilian coast. “No record has survived of a greater single catastrophe at sea, and blame for it must go not, as one might unthinkingly assume, to Fortune, but to the commanders,” who had been warned by experienced pilots not to sail along the coastline facing the Libyan Sea, since “it was too wild for safe anchorage” during one of the frequent storms there (I.xxxvii). “Generally speaking, the Romans rely on force for everything,” regarding “nothing as impossible once they have made up their minds” (I.xxxvii). Such martial bravado often serves them well, especially on land, but the sea is more yielding to Fortune, and Fortune there is far more powerful than men, even Romans.
The war thus proved an equal struggle for many years, gouging each other on land and at sea “like pedigree fighting cocks” (lvii). Or, deploying another metaphor in describing the battles led by the great Carthaginian commander Hamilcar Barca and the Roman, Lucius Junius Pullus , “I cannot here give a thorough account of these struggles; the opposing generals were like a pair of exceptionally brave and skillful boxers fighting it out in a contest for first prize, who pummel each other so incessantly with blow after blow that it is impossible for either the contestants or the spectators to note and anticipate every single attack or punch, thought the overall vigor and determination displayed by the two men can be used to gain an adequate impression of their skill and strength and courage” (I.lvii). After twenty-four years of such struggle, the Romans’ persistence in fighting at sea finally made the Carthaginian occupation of Sicily untenable; they agreed to evacuate not only Sicily but all the islands between Sicily and Italy.
“Powers beyond the Romans’ control, such as Fortune, had no bearing on the assurance with which they set out to make themselves rulers and masters of the whole world; they had perfectly reasonable grounds for this, because of the training they received in the course of this critical and colossal war, and it was this training that enabled them to attain their objective” (I.lxii). The experience gained in this initial, prolonged struggle in effect both toughened and refined the overall character of their regime, which Polybius will describe more fully in Book VI—where it will, he assures us, “receive the prominence it deserves and will repay careful attention from my readers” (I.lxiv).
In the aftermath of their defeat, the Carthaginians faced a major civil war, a war caused by the commercial republican character of their own regime. Commerce lends itself to sea-craft, and Carthage held their own in the Mediterranean. Commerce does not lend itself to land armies, at least not to the extent that the military ethos of Roman republicanism did. As a result, the Carthaginians employed mercenary troops consisting of “various barbarian tribes”—unhesitatingly warlike, to be sure, but none too amenable to military organization and discipline (I.lxv). Having lost a long and expensive war, the Carthaginians couldn’t pay their troops, assuming “that they could get the mercenaries to forgo some of their back pay, if they made them all welcome en masse in Carthage” (I.lxvi). Still wanting the money owed them, and little scrupulous about how to obtain it, the barbarians almost immediately took to crime; more generally, “the unruliness of the mob became a matter of concern” (I.lxvi). Even after they were relocated to the town of Sicca, in Tunis, mutiny threatened. “But all the different peoples and languages created nothing but an incoherent muddle, and the state of the army may truly be described as one of frenzy”; “while ethnic pluralism in any army is a good way of reducing the chances of concerted dissidence or insubordination, it is a very bad idea when the men are resentful or hostile or mutinous, and need to have things explained to them, to be calmed down, and to have their false impressions corrected” (I.lxvii) Such men “behave in a deranged fashion, like the most savage of beasts” (I.lxvii). Too late, “the Carthaginians clearly understood how stupid they had been, and the magnitude of their errors” (I.lxviii). Even when the Carthaginians were able to meet their initial demands, the mercenaries upped the price of settlement.
On top of that, Libyan rebels organized the mercenaries and “openly made war on the Carthaginians” (I.lxx). “The Carthaginians had always depended on the produce of their farmland [in Libya] to sustain them in their private lives,” with “mercenary troops [to] do their fighting for them. But now they had lost all of these resources at once, and as if that were not enough, these resources were being deployed against them” (lxxi). “Previously, they had been challenging the Romans for possession of Sicily, but now, with a civil war on their hands, their very existence and their homeland were at stake,” far more than it had been when the Romans sent their naval forces against them (I.lxxi). As a result of the Sicilian War, they had no ships in reserve; they had no supplies in the territories beyond the contested ground of Libya, and “there was no chance of any support from friends and allies abroad,” perhaps because a civil war didn’t threaten foreigners (I.lxxi).
They had no one to blame but themselves because “during the Sicilian War they had felt themselves justified in treating their Libyan subjects harshly,” taking half of their agricultural produce from them for decades and doubling the tax rate in Libyan cities and towns (I.lxxii). This notwithstanding, the commercial republic, despite its paucity of homegrown soldiers, did have capable generals. Hamilcar Barca was the greatest of them, but Hanno, who had served as military governor of the province so harshly during the Sicilian War, was a better general than civil administrator. The Carthaginians put him in charge of suppressing the revolt. Unfortunately, although he was good at war preparations he was “generally incompetent and negligent” on the battlefield (I.lxxiv). He had never fought battle-hardened troops before, having been detailed to defend Carthage against the Numidians, a nation whose troops “would vanish over the horizon and flee for two or three days once they had been turned in battle” (I.lxxiv). The mercenaries were tougher than that. Hanno was relieved by Hamilcar Barca, who made alliance with a young Numidian aristocrat who had Carthaginian ancestors. Combined, the Carthaginian and Numidian troops crushed the rebels in one battle, only to suffer reverses later on—reverses so severe that Carthage itself was besieged.
Enter Hieron of Syracuse, who sent aid to Carthage after making “sure that it was in his own best interests…that Carthage should survive,” as “he did not want to see the stronger side in the Rome-Carthage balance to gain its objective without any struggle” (I.lxxxiii). “This was sound and sensible thinking on his part: such a situation should never be ignored, nor should one help anyone gain so much power that disagreement becomes impossible even when everyone knows where justice lies” (I.lxxxiii). Even Rome itself backed Carthage, perhaps because it preferred to deal with a civilized rival that it had defeated than an uncivilized one of the sort which had threatened Rome itself in years past. This policy served them well in the short run, although in the longer term they would regret it.
Polybius hints at why the Romans might regret the preservation of Carthage against the barbarians when he recounts the end of the war. True, “the mercenaries proved themselves the equals of their opponents in terms of tactics and daring, but often found themselves at a disadvantage because of inexperience. In fact, it looks as though it was possible at that time to see at first hand the great difference between generalship, with its scientifically acquired experience, and the mindless knack of soldiering, which lacks such experience.” (I.lxxxiv). Hamilcar fought “like a good backgammon player,” dividing and trapping his enemy in ambushes; “anyone taken alive was thrown to the elephants” (I.lxxxiv). “In the end,” the mercenaries “were reduced by starvation to cannibalism—divine retribution for their violation of the laws of gods and men in the way they treated others” (I.lxxxiv). First, they ate their prisoners, then their slaves; when “the officers were sure that the men would be driven by the severity of their suffering to make them their next victims” (officers, after all, tend to be sleeker and better-fed than common soldiers) they treated for peace. Hamilcar seized them as hostages when they arrived in his camp to negotiate the surrender then surrounded the Libyans and their barbarian allies and “slaughtered them all” (I.lxxxv). One of the rebel leaders was “crucified for all to see” (I.lxxxvi). His partner in rebellion escaped and managed to inflict more damage on the Carthaginian forces before his final capture.
At this point Rome took its short-term reward. Over Carthaginian protests, Roman forces seized Sardinia. “With little choice in the matter,” the Carthaginians “not only gave up Sardinia, but paid an additional 1,200 talents to the Romans, to avoid facing another war for the time being” (I.xxxvii). But as civilized masters of war, they were not yet done with the Romans.
Indeed, “as soon as they had settled affairs in Libya, the Carthaginians mustered an army and sent Hamilcar to Iberia,” a mission he undertook with his usual skill (II.i). He stayed there for nine years “and succeeded, by military means or diplomacy, in getting a great deal of the Iberian population to accept Carthaginian dominion” (II.i). He died in battle, not before apprenticing his son, Hannibal, to military and civilian rule, and swearing the boy to nurse a lifelong hatred of Rome.
The Romans had turned their imperial attention to Illyria and eastern Europe, where Demetrius II, king of Macedon, had bribed the Illyrian king to attempt to lift the siege of the Greek city of Medion, besieged by the Aetolians. The Illyrians and Medionites routed the Aetolians, lifting the siege. Polybius takes the opportunity to emphasize the power of Fortune. “It was as though Fortune were deliberately using [the Medionites’] situation to demonstrate her power to all of us, by allowing them to do to their enemies exactly what, not long before, they had expected their enemies to very shortly be doing to them. the lesson the Aetolians taught everyone else by their unexpected setback was never to treat a future event as if it were a fait accompli, and never to look forward with any certainty to anything that may yet turn out quite different. mere mortals should always make allowance for the unexpected, especially in warfare.” (II.iv).
Nor was Fortune done with her instruction. The Illyrian king died of pleurisy after his drunken victory revels, leaving his wife Teuta as inheritor of the throne. “Typically, given the way a woman’s mind works, she could see nothing apart from the victory they had just won and failed to take account of what was happening elsewhere” directing her officers to go on a plundering expedition along the coastline of Elis and Messenia (II.iv). They seized the Epirus by bribing Gaul mercenaries stationed there; the Epirots asked both the Aetolian League and the Achaean League for assistance in retaking their polis. Unaccountably, after their allies succeeded in expelling the Illyrians, the Epirots entered into an alliance with their erstwhile enemies against the two leagues. “The stupidity of this way of treating benefactors was obvious, but it showed how fundamentally their policies lacked intelligent guidance. When disasters are unforeseeable, as happens in the lives of men, we blame not the victims, but Fortune and any human agents who were responsible; but when someone’s stupid behavior brings utter ruin down on himself, when he could have avoided it, everyone recognizes that the victim himself is at fault.” (II.vi-vii). From trusting the Gauls to betraying their allies, the Epirots blundered their way towards a more lasting defeat, later on.
Meanwhile, Queen Teuta’s continued depredations began to interest Rome. She treated Roman envoys “with an air of arrogance and disdain” (II.viii), pretending that the marauding Illyrian ships were mere privateers over whom she exercised no control. When the younger of the two envoys reprimanded her for this policy she had him murdered “in defiance of the law of nations” (II.viii). “When news of the murder reached Rome, the woman’s crime aroused such anger that military preparations became the first order of priority, and they set about calling up their legions and gathering a fleet” (II.viii). For her part, Queen Teuta ordered her forces to besiege the Greek city of Corcyra, both the Aetolians and the Achaeans sent ships in an effort to lift the siege. But the Illyrians won the ensuing naval battle. Then the Roman navy arrived in Corcyrea, where they were welcomed by Demetrius of Macedon, who had allied with Teuta, occupied the city, but now saw good reason to cede it to the Romans, rightly calculating what the new balance of power in Greece was likely to become. With their habitual thoroughness, the Romans proceeded to wrest several Greek cities from Illyrian hands, leaving their administration to their newfound ally, Demetrius. Reduced to a more sensible mood, Queen Teuta concluded a peace treaty with the Roman general, Postumius, who then sent embassies to the Aetolians and Achaeans to “explain why they had fought a war on foreign soil” and to show them the treaty with Illyria. “The treaty made life considerably more secure for the Greeks, because at that time the Illyrians were not particular about whom they attacked; no one was spared their hostility” (II.xii). The Romans followed up this first military expedition to Greek territory with diplomatic missions to Corinth and Athens.
In Iberia, Hamilcar Barca’s son-in-law, Hasdrubal, succeeded him as provincial governor of Iberia. “The Romans could see that the Carthaginians were creating a larger and more formidable empire than before, and they committed themselves to a course of interference in Iberian affairs. They realized that they had been caught napping while the Carthaginians assembled a large army, so they wanted to move things along as quickly as possible, but in the short term they did not dare to give the Carthaginians an ultimatum or go on the offensive against them, because of the looming threat of a Celtic invasion, which they expected any day. They decided they had to pacify Hasdrubal and make sure he was no kind of threat, so that they could then attack the Celts and fight to the finish.” (II.xiii). They enacted a treaty with Hasdrubal, whereby the Carthaginians pledged not to cross the Ebro River in northeastern Iberia with their troops. “And then the Romans immediately embarked upon the war against the Celts” (II.xiii).
Polybius takes care to describe the Celtic regime, which pervaded a set of tribes, ruling no fixed polis or empire. “Their villages were unwalled and lacked any other civilized amenities. They lived simple lives, sleeping on straw and eating meat skilled in nothing apart from warfare and farming, without the slightest inkling of any other science or craft. their wealth consisted of cattle and gold, because they were easily transportable wherever they went; whatever the circumstances, they could move these possessions from one place to another at whim. The most important thing was for a man to have a following, because whoever was thought to have the largest number of attendants and retainers was held in awe as the most powerful chieftain among them.” (II.xvii). They had warred with the Romans off and on for a long time, sometimes in alliance with the Gauls, who proved no more reliable allies of theirs than they did anywhere, with anyone.
By 232 BC, the troubles renewed, and in 226 the Gauls entered the fray, crossing the Alps into Italy. This actually helped Rome, as “the people of Italy were so frightened by the approach of the Gauls that they no longer thought of themselves as fighting in support of Rome, nor did it cross their minds that the purpose of the war was Roman supremacy; all the allies took the danger personally and saw it as a direct threat to their own cities and lands, and were happy to do what the Romans wanted” (II.xxiii). After inflicting heavy casualties on Rome and its allies, putting Rome itself in “terrible danger,” the Celts were defeated (II.xxxi). “In terms of the depravity and recklessness of the contestants, and also of the numbers of combatants and casualties involved in the battles,” this war “was second to none in recorded history” (II.xxxv). More than that, it is worth recording because “if future generations are unaware of these events, they will be utterly distraught at sudden and unexpected barbarian invasions, when all they need to do is briefly bear in mind that any barbarian threat is temporary and easily disposed of, and then they can endure the invasion and exhaust every last resource at their command, rather than give up anything important” (II.xxxv). Despite the “myriads of men” in the barbarian host, despite “all their fearlessness and their armament”—all elements of their regime, their way of life—they were “destroyed by the resolve and the resources of those who faced danger intelligently and rationally” (II.xxxv). No civilized people uncorrupted by luxury need be “dismayed by immense quantities of supplies and weapons, and hordes of troops, into abandoning all hope and failing to fight for his land and the country of his birth,” as the Greeks were in Polybius’ time, but as the Romans were not, and as the Greeks were not before that, when they confronted the Persian invasion chronicled by Herodotus (II.xxxv).
In Iberia, after Hasdrubal’s assassination by a Celt who harbored a personal grudge against him, young Hannibal took over the Carthaginian forces. True to his vow to the gods before his father, “right from the start of his command, he made no secret of his intention to make war on the Romans” (II.xxxvi). His spectacular crossing of the Alps and the ensuing “Hannibalic War” will occupy Polybius’ attention throughout Book III. But it is the war between the Aetolian League and the Achaean League (with Macedon as its ally) serves as Polybius’ final topic in Book II. This war effected the beginning of the unification of the Peloponnese in a federal system of poleis. As a political historian, Polybius will explain how this unifying movement compared and contrasted with the successful unification of Italy under Rome.
“There had been many attempts in the past to unify the Peloponnesians, but none of them succeeded because each polis was interested only in its own supremacy, not in freedom for all alike” (II.xxxvii). By Polybius’ time, he writes, “this cause has made considerable progress” because the regimes by then were “more or less identical from city to city” (II.xxxvii). It was the Achaeans who unified Greece for a time, as a result of their victory in the so-called “Social War.” “Why,” Polybius asks, “were they and everyone else in the Peloponnese happy to take on the Achaean system of government and the Achaean name? What induced them to do so?” (II.xxxviii). To say ‘Fortune’ will not do. “We need to look deeper for a reason, knowing that even things that seem improbable have causes, just as much as comprehensible events, because otherwise they would not happen” (II.xxxviii).
Polybius locates that cause in the same place he locates the cause of Roman rule: the regime. “One would be hard put to find equality and the right to speak one’s mind in assembly—in short, the regime and principles of true democracy—in a purer form than among the Achaeans” (II.xxxviii). This mattered ‘geopolitically’ because democracy “won over” Greeks initially suspicious of it “by the persuasive power of reason”; those not so persuaded acceded at first to “the timely application of force” but soon “exchanged resistance for contentment” because democracy “reserved no privileges for any of her original devotees and treated all as equals, regardless of when they came over to her side”—a lesson followed by the Framers of the United States Constitution when they granted each new state equal standing in the American Union (II.xxxviii). “Democracy, then, was the instigator and agent, and we look no further to explain how the Peloponnesians came to cooperate and forge their current prosperity,” as well (II.xxxviii). Whereas Greek cities had been “rife with murder, conflict, and mayhem of all kinds,” it was only “the Achaeans whose integrity they trusted and to whom they looked for a solution to their current troubles” (II.xxxix).
The League was founded in 280 BC, with four members; in ten years it had ten members. Its founders had a model in the original Achaean League, founded long before but conquered by the Macedonians. Although that league featured monarchic regimes, the relations among them were democratic, with each of its twelve poleis having an equal vote on common policies. The new league was democratic in respect of both its federal relations and the regimes of the poleis composing it.
A major advance for the League came in 243 BC, when the twenty-year-old Aratus “liberated his city,” Sicyon, “from tyranny through his own valor and courage, and brought Sicyon into the League. He had always been an admirer of the Achaeans’ political principles.” (II.xliii). As a general, he liberated Corinth and Megara, at the same time that Rome forced the Carthaginians to evacuate Sicily. All [Aratus’] policies and all his actions were directed towards a single goal: expelling the Macedonians from the Peloponnese, banishing the tyrants, and guaranteeing every polis its ancestral freedom, as a member of the League” (II.xliii). Initially, the Aetolians allied with the Macedonians in attempted to destroy the League, but after the death of the Aetolian monarch in 239 the two leagues joined forces against the Macedonians. Ten years later, with the death of the Macedonian king, Demetrius II, the remaining tyrants in the Peloponnese abdicated, seeing that they could no longer maintain their rule without their principal backer. This unified the Achaean region in a single federation.
The Aetolians, “an innately aggressive and rapacious people,” soon broke their alliance and renewed their alliance with Macedon (II.xlv). They also hoped to bring the Spartans into their alliance. “In all probability they would soon have met with success, except they overlooked a critical flaw in their plans. They failed to take into consideration that this initiative of theirs would bring them up against Aratus, a man who could cope with any crisis.” (II.xlv). Aratus did the Aetolians one better, making a secret alliance with the Macedonian king, Antigonus Doson, persuading him that the Aetolians were more dangerous to Macedon than the Achaeans. Defeated in three battles by the Spartans, he then called upon the Macedonians for assistance; the Achaeans appointed Antigonus as the commander-in-chief of the allied armies. In 222, he defeated the Spartans. Crucially, and despite the harshness of the Spartans during the war (they destroyed the Achaean polis of Megalopolis, Polybius’ home town), his treatment of the enemy “was nothing but generous and humane, and he reestablished their ancestral regime,” which had been overthrown by the tyrant Cleomenes, the Spartan ruler during the war (II.lxx). “He had personally made it possible for all the inhabitants of Greece to look forward to a better future, not just as a result of what he had done for them in the field, but even more because he was a man of principle and integrity” (II.lxx).
The Cleomenean War, as this one was called, preceded the Social War, to which Polybius will turn in a subsequent book of this pentad. He has shown how the Romans, having established hegemony in Italy, began their overseas empire by taking Sicily and Sardinia from the Carthaginians and by a short-lived foray into Illyria. He has described the Carthaginian consolidation of rule in Iberia and the founding and defense of the Achaean League. All of these events will contribute the establishment of the Roman empire throughout the Mediterranean, the “known world.”
In the course of relating these events and establishing their causes, Polybius clearly presents the elements of the political education he intends to provide through political history, which provides those who aspire to statesmanship or to historiography (Polybius was an accomplished practitioner of both arts) with some of the experience needed to build up the practical wisdom necessary for success in either of those fields of endeavor. He invites his readers to learn politics by considering four main topics.
First, he measures the strength and limitations of Fortune. No doubt, there are forces beyond human control—the sudden storm, the untimely illness, the small accident that brings on a calamitous outcome. But although Polybius would never claim that Fortune can be mastered, as his admirer Machiavelli contends, he does think that intelligent and experienced statesmen and generals can minimize it, often by avoiding extremes of passion and the actions prompted by them. This is the advantage civilized peoples enjoy over barbarians, and he takes care to notice both the Carthaginian defeat of barbarian mercenaries and the Roman defeat of the combined forces of Celts and Gauls—demonstrating that two sharply differing republican regimes could knock down the worst efforts of warlike, sizeable but ill-organized and ill-disciplined tribal hordes.
Second, and with respect to regimes, he contrasts the military republic of Rome with the commercial republic of Carthage. The disadvantage of the commercial republic is its practice of trying to buy the armies that defend it; mercenaries prove less reliable than one’s own troops (and here Machiavelli wholeheartedly concurs). A potential weakness of the military republic is over-reliance on force; accordingly, Polybius emphasizes Rome’s civilian control of its military, its successful diplomatic efforts, and the effectiveness of a prudent mixture of persuasion and military action seen in Aratus, the great statesman/general of the Achaean League.
Third, in addition to regimes he addresses the matter of what might be called ‘states’—political communities organized not only according to the number and types of rulers, ruling institutions, purposes, and ways of life but with respect to size and degree of centralization. Tribal organizations are too small by themselves, too apt to fall into frequent disputes amongst themselves when confederated, and almost always too impassioned to think straight. Empires consist of the rule of one people over a collection of subordinate peoples. They defeat barbaric tribes, thanks to their superior organization and rationality. They can be vulnerable to civil war, including civil wars fomented by their enemies, who aim at re-dividing them out of self-defense or in the hope of conquering them and incorporating them into their own empires. Despite the spectacular success of Rome, Polybius seems to favor the federal state, seen in his native Achaea, whereby democratic-republican regimes combine for purposes of defense and commerce.
Finally, in terms of geopolitics he describes the beginnings of the interconnectedness of Italy, Libya, Greece, and Asia. He does so, however, in a manner distinct, and distinctly more accurate than, the ‘geopoliticians’ of the last century-and-a-half, often devotees of the German school of Realpolitik, who reduce politics to power relations. That is, not only are the Mediterranean regions shown to be interconnected militarily, politically, and commercially, his four topics intertwine, as well. Under Polybius’ Aristotelian gaze, Realpolitik looks not so real and not so politic.
