Something similar happened to the gold. The aureus, though it kept its fineness, lost in weight down to Constantine. In the reign of Augustus it equalled one-fortieth of a Roman pound of gold, in that of Nero one forty-fifth, in that of Caracalla but one-fiftieth, in that of Diocletian one-sixtieth, and in that of Constantine one seventy-second, when the coin ceased passing by tale and was taken only by weight.39
The repudiation of the denarius was an act of bankruptcy; nor did the financial position improve while the administration remained at Rome. Therefore the inference is that, toward the middle of the third century, Italy had lost the treasure she had won in war, which had gradually gravitated to the centre of exchanges. This inference is confirmed by history. The movements of Diocletian seem to demonstrate that after 250 A.D. Rome ceased to be either the political or commercial capital of the world.
Unquestionably Diocletian must have lived a life of intense activity at the focus of affairs, to have raised himself from slavery to the purple at thirty-nine; and yet Gibbon thought he did not even visit Rome until he went thither to celebrate his triumph, after he had been twenty years upon the throne. He never seemed anxious about the temper of the city. When proclaimed emperor he ignored Italy and established himself at Nicomedia on the Propontis, where he lived until he abdicated in 305. His personal preferences evidently did not influence him, since his successors imitated his policy; and everything points to the conclusion that he, and those who followed him, only yielded to the same resistless force which fixed the economic capital of the world upon the Bosphorus. In the case of Constantine the operation of this force was conspicuous, for it was not only powerful enough to overcome the habit of a lifetime, but to cause him to undertake the gigantic task of building Constantinople.
Constantine was proclaimed in Britain in 306, when only thirty-two. Six years later he defeated Maxentius, and then governed the West alone until his war with Licinius, whom he captured in 323 and afterward put to death. Thus, at fifty, he returned to the East, after an absence of nearly twenty years, and his first act was to choose Byzantium as his capital, a city nearly opposite Nicomedia.
The sequence of events seems plain. Very soon after the insolvency of the government at Rome, the administration quitted the city and moved toward the boundary between Europe and Asia; there, after some forty years of vacillation, it settled permanently at the true seat of exchanges, for Constantinople remained the economic centre of the earth for more than eight centuries.
Similar conclusions may be drawn from the fluctuations of the currency. At Rome the coin could not be maintained at the standard, because of adverse exchanges; but when the political and economic centres had come to coincide, at a point upon the Bosphorus, depreciation ceased, and the aureus fell no further.
This migration of capital, which caused the rise of Constantinople, was the true opening of the Middle Ages, for it occasioned the gradual decline of the rural population, and thus brought about the disintegration of the West. Victory carried wealth to Rome, and wealth manifested its power in a permanent police; as the attack in war gained upon the defence, and individual resistance became impossible, transportation grew cheap and safe, and human movement was accelerated. Then economic competition began, and intensified as centralization advanced, telling always in favour of the acutest intellect and the cheapest labour. Soon, exchanges became permanently unfavourable, a steady drain of bullion set in to the East, and, as the outflow depleted the treasure amassed at Rome by plunder, contraction began, and with contraction came that fall of prices which first ruined, then enslaved, and finally exterminated, the native rural population of Italy.
In the time of Diocletian, the ancient silver currency had long been repudiated, and, in his well-known edict, he spoke of prices as having risen ninefold, when reckoned in the denarii of base metal; the purchasing power of pure gold and silver had, however, risen very considerably in all the western provinces. Nor was this all. It appears to be a natural law that when social development has reached a certain stage, and capital has accumulated sufficiently, the class which has had the capacity to absorb it shall try to enhance the value of their property by legislation. This is done most easily by reducing the quantity of the currency, which is a legal tender for the payment of debts. A currency obviously gains in power as it shrinks in volume, and the usurers of Constantinople intuitively condensed to the utmost that of the Empire. After the insolvency under Elagabalus, payments were exacted in gold by weight, and as it grew scarcer its value rose. Aurelian issued an edict limiting its use in the arts; and while there are abundant reasons for inferring that silver also gained in purchasing power, gold far outstripped it. Although no statistics remain by which to establish, with any exactness, the movement of silver in comparison with commodities, the ratio between the precious metals at different epochs is known, and gold appears to have doubled between Cæsar and Romulus Augustulus.
As gold had become the sole legal tender, this change of ratio represents a diminution, during the existence of the Western Empire, of at least fifty per cent in the value of property in relation to debt, leaving altogether out of view the appreciation of silver itself, which was so considerable that the government was unable to maintain the denarius.40
Resistance to the force of centralized wealth was vain. Aurelian’s attempt to reform the mints is said to have caused a rebellion, which cost him the lives of seven thousand of his soldiers; and though his policy was continued by Probus, and Diocletian coined both metals again at a ratio, expansion was so antagonistic to the interests of the monied class that, by 360, silver was definitely discarded, and gold was made by law the only legal tender for the payment of debts.41 Furthermore, the usurers protected themselves against any possible tampering with the mints by providing that the solidus should pass by weight and not by tale; that is to say, they reserved to themselves the right to reject any golden son which contained less than one seventy-second of a pound of standard metal, the weight fixed by Constantine.42
Thus, at a time when the exhaustion of the mines caused a failure in the annual supply of bullion, the old composite currency was split in two, and the half retained made to pass by weight alone, so as to throw the loss by clipping and abrasion upon the debtor. So strong a contraction engendered a steady fall of prices, a fall which tended rather to increase than diminish as time went on. But in prolonged periods of decline in the market value of agricultural products, farmers can with difficulty meet a money rent, because the sale of their crops leaves a greater deficit each year, and finally a time comes when insolvency can no longer be postponed.
In his opening chapter Gibbon described the Empire under the Antonines as enjoying “a happy period of more than fourscore years” of peace and prosperity; and yet nothing is more certain than that this halcyon age was in reality an interval of agricultural ruin. On this point Pliny was explicit, and Pliny was a large land-owner.
He wrote one day to Calvisius about an investment, and went at length into the condition of the property. A large estate adjoining his own was for sale, and he was tempted to buy, “for the land was fertile, rich, and well watered,” the fields produced vines and wood which promised a fair return, and yet this natural fruitfulness was marred by the misery of the husbandmen. He found that the former owner “had often seized the ‘pignora,’ or pledges [that is, all the property the tenants possessed]; and though, by so doing, he had temporarily reduced their arrears, he had left them” without the means of tilling the soil. These tenants were freemen, who had been unable to meet their rent because of falling prices, and who, when they had lost their tools, cattle, and household effects, were left paupers on the farms they could neither cultivate nor abandon. Consequently the property had suffered, the rent had declined, and for these reasons and “the general hardness of the times,” its value had fallen from five million to three million sesterces.43
In another letter he explained that he was detained at home making new arrangements with his tenants, who were apparently insolvent, for “in the last five years, in spite of great concessions, the arrears have increased. For this reason most [tenants] take no trouble to diminish their debt, which they despair of paying. Indeed, they plunder and consume what there is upon the land, since they think they cannot save for themselves.” The remedy he proposed was to make no more money leases, but to farm on shares.44
The tone of these letters shows that there was nothing unusual in all this. Pliny nowhere intimated that the tenants were to blame, or that better men were to be had. On the contrary, he said emphatically that in such hard times money could not be collected, and therefore the interest of the landlord was to cultivate his estates on shares, taking the single precaution to place slaves over the tenants as overseers and receivers of the crops.
In the same way the digest referred to such arrears as habitual.45 In still another letter to Trajan, Pliny observed, “Continuæ sterilitates cogunt me de remissionibus cogitare.”46 Certainly these insolvent farmers could have held no better position when working on shares than before their disasters, for as bankrupts they were wholly in their creditors’ power, and could be hunted like slaves, and brought back in fetters if they fled. They were tied to the property by a debt which never could be paid, and they and their descendants were doomed to stay for ever as coloni or serfs, chattels to be devised or sold as part of the realty. In the words of the law, “they were considered slaves of the land.”47 The ancient martial husbandman had thus “fallen from point to point, from debt to debt, into an almost perpetual subjection.”48 Deliverance was impossible, for payment was out of the question. He was bound to the soil for his life, and his children after him inherited his servitude with his debt.
The customs, according to which the coloni held, were infinitely varied; they differed not only between estates, but between the hands on the same estate. On the whole, however, the life must have been hard, for the serfs of the Empire did not multiply, and the scarcity of rural labour became a chronic disease.
Yet, relatively, the position of the colonus was good, for his wife and children were his own; slavery was the ulcer which ate into the flesh, and the Roman fiscal system, coupled as it was with usury, was calculated to enslave all but the oligarchy who made the laws.
The taxes of the provinces were assessed by the censors and then sold for cash to the publicans, who undertook the collection. Italy was at first exempted, but after her bankruptcy she shared the common fate. Companies were formed to handle these ventures. The knights usually subscribed the capital and divided the profits, which corresponded with the severity of their administration; and, as the Roman conquests extended, these companies grew too powerful to be controlled. The only officials in a position to act were the provincial governors, who were afraid to interfere, and preferred to share in the gains of the traffic, rather than to run the risk of exciting the wrath of so dangerous an enemy.49
According to Pliny the collection of a rent in money had become impossible in the reign of Trajan. The reason was that with a contracting currency prices of produce fell, and each year’s crop netted less than that of the year before; therefore a rent moderate in one decade was extortionate in the next. But taxes did not fall with the fall in values; on the contrary, the tendency of centralization is always toward a more costly administration. Under Augustus, one emperor with a moderate household sufficed; but in the third century Diocletian found it necessary to reorganize the government under four Cæsars, and everything became specialized in the same proportion.
In this way the people were caught between the upper and the nether millstone. The actual quantity of bullion taken from them was greater, the lower prices of their property fell, and arrears of taxes accumulated precisely as Pliny described the accumulation of arrears of rent. These arrears were carried over from reign to reign, and even from century to century; and Petronius, the father-in-law of Valens, is said to have precipitated the rebellion of Procopius, by exacting the tribute unpaid since the death of Aurelian a hundred years before.
The processes employed in the collection of the revenue were severe. Torture was freely used,50 and slavery was the fate of defaulters. Armed with such power, the publicans held debtors at their mercy. Though usury was forbidden, the most lucrative part of the trade was opening accounts with the treasury, assuming debts, and charging interest sometimes as high as fifty per cent. Though, as prices fell, the pressure grew severer, the abuses of the administration were never perhaps worse than toward the end of the Republic. In his oration against Verres, Cicero said the condition of the people had become intolerable: “All the provinces are in mourning, all the nations that are free are complaining; every kingdom is expostulating with us about our covetousness and injustice.”51
The well-known transactions of Brutus are typical of what went on wherever the Romans marched. Brutus lent the Senate of Salaminia at forty-eight per cent a year. As the contract was illegal, he obtained two decrees of the Senate at Rome for his protection, and then to enforce payment of his interest, Scaptius, his man of business, borrowed from the governor of Cilicia a detachment of troops. With this he blockaded the Senate so closely that several members starved to death. The Salaminians, wanting at all costs to free themselves from such a load, offered to pay off both interest and capital at once; but to this Brutus would not consent, and to impose his own terms upon the province he demanded from Cicero more troops, “only fifty horse.”52
When at last, by such proceedings, the debtors were so exhausted that no torment could wring more from them, they were sold as slaves; Nicodemus, king of Bithynia, on being reproached for not furnishing his contingent of auxiliaries, replied that all his able-bodied subjects had been taken by the farmers of the revenue.53 Nor, though the administration doubtless was better regulated under the Empire than under the Republic, did the oppression of the provinces cease. Juvenal, who wrote about 100, implored the young noble taking possession of his government to put some curb upon his avarice, “to pity the poverty of the allies. You see the bones of kings sucked of their very marrow.”54 And though the testimony of Juvenal may be rejected as savouring too much of poetical licence, Pliny must always be treated with respect. When Maximus was sent to Achaia, Pliny thought it well to write him a long letter of advice, in which he not only declared that to wrest from the Greeks the shadow of liberty left them would be “durum, ferum, barbarumque;” but adjured him to try to remember what each city had been, and not to despise it for what it was.55
Most impressive, perhaps, of all, is the statement of Dio Cassius that the revolt led by Boadicea in Britain in 61 A.D., which cost the Romans seventy thousand lives, was provoked by the rapacity of Seneca, who, having forced a loan of ten million drachmas ($1,670,000) on the people at usurious interest, suddenly withdrew his money, thereby inflicting intense suffering.56 As Pliny said with bitterness and truth, “The arts of avarice were those most cultivated at Rome.”57
The stronger type exterminated the weaker; the money-lender killed out the husbandman; the race of soldiers vanished, and the farms, whereon they had once flourished, were left desolate. To quote the words of Gibbon: “The fertile and happy province of Campania … extended between the sea and the Apennines from the Tiber to the Silarus. Within sixty years after the death of Constantine, and on the evidence of an actual survey, an exemption was granted in favour of three hundred and thirty thousand English acres of desert and uncultivated land; which amounted to one-eighth of the whole surface of the province.”58
It is true that Gibbon, in this paragraph, described Italy as she was in the fourth century, just before the barbarian invasions, but a similar fate had overtaken the provinces under the Cæsars. In the reign of Domitian, according to Plutarch, Greece had been almost depopulated.
“She can with much difficulty raise three thousand men, which number the single city of Megara sent heretofore to the battle of Platæa… For of what use would the oracle be now, which was heretofore at Tegyra or at Ptous? For scarcely shall you meet, in a whole day’s time, with so much as a herdsman or shepherd in those parts.”59
Wallon has observed that Rome, “in the early times of the Republic, was chiefly preoccupied with having a numerous and strong population of freemen. Under the Empire she had but one anxiety – taxes.”60
To speak with more precision, force changed the channel through which it operated. Native farmers and native soldiers were needless when such material could be bought cheaper in the North or East. With money the cohorts could be filled with Germans; with money, slaves and serfs could be settled upon the Italian fields; and for the last century, before the great inroads began, one chief problem of the imperial administration was the regulation of the inflow of new blood from without, lacking which the social system must have collapsed.
The later campaigns on the Rhine and the Danube were really slave-hunts on a gigantic scale. Probus brought back sixteen thousand men from Germany, “the bravest and most robust of their youth,” and distributed them in knots of fifty or sixty among the legions. “Their aid was now become necessary… The infrequency of marriage, and the ruin of agriculture, affected the principles of population; and not only destroyed the strength of the present, but intercepted the hope of future generations.”61
His importations of agricultural labour were much more considerable. In a single settlement in Thrace, Probus established one hundred thousand Bastarnæ; Constantius Chlorus is said to have made Gaul flourish by the herds of slaves he distributed among the landlords; in 370, large numbers of Alemanni were planted in the valley of the Po, and on the vast spaces of the public domain there were barbarian villages where the native language and customs were preserved.
Probably none of these Germans came as freemen. Many, of course, were captives sold as slaves, but perhaps the majority were serfs. Frequently a tribe, hard pressed by enemies, asked leave to pass the frontier, and settle as tributaries, that is to say as coloni. On one such occasion Constantius II. was nearly murdered. A body of Limigantes, who had made a raid, surrendered, and petitioned to be given lands at any distance, provided they might have protection. The emperor was delighted at the prospect of such a harvest of labourers, to say nothing of recruits, and went among them to receive their submission. Seeing him alone, the barbarians attacked him, and he escaped with difficulty. His troops slaughtered the Germans to the last man.
This unceasing emigration gradually changed the character of the rural population, and a similar alteration took place in the army. As early as the time of Cæsar, Italy was exhausted; his legions were mainly raised in Gaul, and as the native farmers sank into serfdom or slavery, and then at last vanished, recruits were drawn more and more from beyond the limits of the Empire. At first they were taken singly, afterwards in tribes and nations, so that, when Aëtius defeated Attila at Châlons, the battle was fought by the Visigoths under Theodoric, and the equipment of the Romans and Huns was so similar that when drawn up the lines “presented the image of civil war.”
This military metamorphosis indicated the extinction of the martial type, and it extended throughout society. Rome not only failed to breed the common soldier, she also failed to produce generals. After the first century, the change was marked. Trajan was a Spaniard, Septimius Severus an African, Aurelian an Illyrian peasant, Diocletian a Dalmatian slave, Constantius Chlorus a Dardanian noble, and the son of Constantius, by a Dacian woman, was the great Constantine.
All these men were a peculiar species of military adventurer, for they combined qualities which made them, not only effective chiefs of police, but acceptable as heads of the civil bureaucracy, which represented capital. Severus was the type, and Severus has never been better described than by Machiavelli, who said he united the ferocity of the lion to the cunning of the fox. This bureaucracy was the core of the consolidated mass called the Empire; it was the embodiment of money, the ultimate expression of force, and it recognized and advanced men who were adapted to its needs. When such men were to be found, the administration was thought good; but when no one precisely adapted for the purple appeared, and an ordinary officer had to be hired to keep the peace, friction was apt to follow, and the soldier, even though of the highest ability, was often removed. Both Stilicho and Aëtius were murdered.
The monied oligarchy which formed this bureaucracy was a growth as characteristic of the high centralization of the age, as a sacred caste is characteristic of decentralization. Perhaps the capitalistic class of the later Empire has been better understood and appreciated by Fustel de Coulanges than by any other historian.
“All the documents which show the spirit of the epoch show that this noblesse was as much honoured by the government as respected by the people… It was from it that the imperial government chose ordinarily its high functionaries.”
These functionaries were not sought among the lower classes. The high offices were not given as a reward of long and faithful service; they belonged by prescriptive right to the great families. The Empire made the wealthy, senators, prætors, consuls, and governors; all dignities, except only the military, were practically hereditary in the opulent class.
“This class is rich and the government is poor. This class is mistress of the larger part of the soil; it is in possession of the local dignities, of the administrative and judicial functions. The government has only the appearance of power, and an armed force which is continually diminishing…
“The aristocracy had the land, the wealth, the distinction, the education, ordinarily the morality of existence; it did not know how to fight and to command. It withdrew itself from military service; more than that, it despised it. It was one of the characteristic signs of this society to have always placed the civil functions not on a level with, but much above, the grades of the army. It esteemed much the profession of the doctor, of the professor, of the advocate; it did not esteem that of the officer and the soldier, and left it to men of low estate.”62
This supremacy of the economic instinct transformed all the relations of life, the domestic as well as the military. The family ceased to be a unit, the members of which cohered from the necessity of self-defence, and became a business association. Marriage took the form of a contract, dissoluble at the will of either party, and, as it was somewhat costly, it grew rare. As with the drain of their bullion to the East, which crushed their farmers, the Romans were conscious, as Augustus said, that sterility must finally deliver their city into the hand of the barbarians.63 They knew this and they strove to avert their fate, and there is little in history more impressive than the impotence of the ancient civilization in its conflict with nature. About the opening of the Christian era the State addressed itself to the task. Probably in the year 4 A.D., the emperor succeeded in obtaining the first legislation favouring marriage, and this enactment not proving effective, it was supplemented by the famous Leges Julia and Papia Poppæa of the year 9. In the spring, at the games, the knights demanded the repeal of these laws, and then Augustus, having called them to the Forum, made them the well-known speech, whose violence now seems incredible. Those who were single were the worst of criminals, they were murderers, they were impious, they were destroyers of their race, they resembled brigands or wild beasts. He asked the equites if they expected men to start from the ground to replace them, as in the fable; and declared in bitterness that while the government liberated slaves for the sole purpose of keeping up the number of citizens, the children of the Marcii, of the Fabii, of the Valerii, and the Julii, let their names perish from the earth.64
