The Western and Eastern Roman Empires by 476 CE
The Western and Eastern Roman Empires by 476 CE

The causes and mechanisms of the fall of the Western Roman Empire are a historical theme that was introduced by historian Edward Gibbon in his 1776 book The History of the Decline and Fall of the Roman Empire. He started an ongoing historiographical discussion about what caused the fall of the Western Roman Empire. The traditional date for the end of the Western Roman Empire is 476 CE when the last Western Roman Emperor was deposed. Gibbon was not the first to speculate on why the empire collapsed, but he was the first to give a well-researched and well-referenced account. Many theories of causality have been explored. In 1984, Alexander Demandt enumerated 210 different theories on why Rome fell, and new theories have since emerged.[1][2] Gibbon himself explored ideas of internal decline (civil wars, the disintegration of political, economic, military, and other social institutions) and of attacks from outside the empire.

Many historians have postulated reasons for the collapse of the Western Roman Empire. Their conclusions usually belong in two broad schools: (1) external, military threats and barbarian invasions or (2) internal, a decline in "civic virtue" and military and economic capability. Most historians believe that the fall was due to a combination of both internal and external factors, but come down more heavily on one or the other as the most important cause of the fall. Modern scholarship has introduced additional factors such as climate change, epidemic diseases, and environmental degradation as important reasons for the decline. Some historians have postulated that the Roman Empire did not fall at all, but that the "decline" was instead a gradual, albeit often violent, transformation into the societies of the Middle Ages.

Comparisons by historians, both professional and amateur, and in literature, both scholarly and popular, of Rome with the decline and fall of other societies have been numerous. "From the eighteenth century onward", historian Glen Bowersock wrote, "we have been obsessed with the fall: it has been valued as an archetype for every perceived decline, and, hence, as a symbol for our own fears."[3]

Overview of historiography

Historiographically, the primary issue historians have looked at when analyzing any theory is the continued existence of the Eastern Empire or Byzantine Empire, which lasted almost a thousand years after the fall of the West. For example, Gibbon implicates Christianity in the fall of the Western Empire, yet the eastern half of the Empire, which was even more Christian than the west in geographic extent, fervor, penetration and vast numbers continued on for a thousand years afterwards (although Gibbon did not consider the Eastern Empire to be much of a success). As another example, environmental or weather changes affected the east as much as the west, yet the east did not "fall."

Theories will sometimes reflect the particular concerns that historians might have on cultural, political, or economic trends in their own times. Gibbon's criticism of Christianity reflects the values of the Enlightenment; his ideas on the decline in martial vigor could have been interpreted by some as a warning to the growing British Empire. In the 19th century, socialist and anti-socialist theorists tended to blame decadence and other political problems. More recently, environmental concerns have become popular, with deforestation and soil erosion proposed as major factors, and destabilizing population decreases due to epidemics such as early cases of bubonic plague and malaria also cited. Global climate changes of 535–536, perhaps caused by the possible eruption of Krakatoa in 535, as mentioned by David Keys and others,[4] is another example. Ideas about transformation without a distinct fall mirror the rise of the postmodern tradition, which rejects periodization concepts (see metanarrative). What is not new are attempts to diagnose Rome's particular problems; already in the early 2nd century, at the height of Roman power, Juvenal in his Satire X criticized the people's obsession with "bread and circuses" and their rulers' excessive efforts to gratify this obsession.

One of the primary reasons for the vast number of theories is the notable lack of surviving evidence from the 4th and 5th centuries. For example, there are so few records of an economic nature that it is difficult to arrive at even a generalization of the economic conditions. As a result, historians must use inductive reasoning in addition to available evidence to imagine how things most probably happened or must use evidence from previous and later periods. As in any field where available evidence is sparse, this ability of historians to imagine the 4th and 5th centuries plays as important a part in shaping our understanding as the available evidence, which means that there is room for endless variety in interpretation.

The end of the Western Roman Empire traditionally has been seen by historians to mark the end of the Ancient Era and beginning of the Middle Ages. More recent schools of history, such as Late Antiquity, offer a more nuanced view from the traditional historical narrative.

There is no consensus on a date for the start of Rome's decline. Gibbon started his account in 98.[citation needed] The year 376 is taken as pivotal by many modern historians.[citation needed] In that year there was an unmanageable influx of Goths and other Barbarians into the Balkan provinces, and the situation of the Western Empire generally worsened thereafter, despite incomplete and temporary recoveries. Significant events include the Battle of Adrianople in 378, the death of Theodosius I in 395 (the last time the Roman Empire was politically unified), the crossing of the Rhine in 406 by Germanic tribes, the execution of Stilicho in 408, the sack of Rome in 410, the death of Constantius III in 421, the death of Aetius in 454, and the second sack of Rome in 455, with the death of Majorian in 461 marking the end of the last opportunity for recovery.

Gibbon took September 4, 476, as a convenient marker for the final dissolution of the Western Roman Empire, when Romulus Augustus, the last Emperor of the Western Roman Empire, was deposed by Odoacer, a Germanic chieftain. Some modern historians question the significance of the events of the year 476 for the end of the western empire.[5] Julius Nepos, the Western emperor recognized by the Eastern Roman Empire, continued to rule in Dalmatia, until he was assassinated in 480. The Ostrogothic rulers of Italia considered themselves upholders of the direct line of Roman tradition, and the Eastern emperors considered themselves the sole rightful Roman rulers of a united empire.[citation needed] Roman cultural traditions continued throughout the territory of the Western Empire, and a recent school of interpretation argues that the great political changes can more accurately be described as a complex cultural transformation rather than a fall.[6]

The decline of the Roman Empire is one of the traditional markers of the end of Classical Antiquity and the beginning of the European Middle Ages. Throughout the 5th century, the Empire's territories in western Europe and northwestern Africa, including Italy, fell to various invading or indigenous peoples in what is sometimes called the Migration period. Although the eastern half still survived with borders essentially intact for several centuries (until the Muslim conquests), the Empire as a whole had initiated major cultural and political transformations since the Crisis of the Third Century, with the shift towards a more openly autocratic and ritualized form of government, the adoption of Christianity as the state religion, and a general rejection of the traditions and values of Classical Antiquity. While traditional historiography emphasized this break with Antiquity by using the term "Byzantine Empire" instead of Roman Empire, recent schools of history offer a more nuanced view, seeing mostly continuity rather than a sharp break. The Empire of Late Antiquity already looked very different from classical Rome.

The Roman Empire emerged from the Roman Republic when Julius Caesar and Augustus Caesar transformed it from a republic into a monarchy. Rome reached its zenith in the 2nd century, then fortunes slowly declined (with many revivals and restorations along the way). The reasons for the decline of the Empire are still debated today, and are likely multiple. Historians infer that the population appears to have diminished in many provinces—especially western Europe—from the diminishing size of fortifications built to protect the cities from barbarian incursions from the 3rd century on. Some historians even have suggested that parts of the periphery were no longer inhabited because these fortifications were restricted to the center of the city only. Tree rings suggest "distinct drying" beginning in 250.[7]

By the late 3rd century, the city of Rome no longer served as an effective capital for the Emperor and various cities were used as new administrative capitals. Successive emperors, starting with Constantine, privileged the eastern city of Byzantium, which he had entirely rebuilt after a siege. Later renamed Constantinople, and protected by formidable walls in the late 4th and early 5th centuries, it was to become the largest and most powerful city of Christian Europe in the Early Middle Ages. Since the Crisis of the Third Century, the Empire was intermittently ruled by more than one emperor at once (usually two), presiding over different regions. At first a haphazard form of power sharing, this eventually settled on an east–west administrative division between the Western Roman Empire (centered on Rome, but now usually presided from other seats of power such as Trier, Milan, and especially Ravenna), and the Eastern Roman Empire (with its capital initially in Nicomedia, and later Constantinople). The Latin-speaking west, under dreadful demographic crisis, and the wealthier[citation needed] Greek-speaking east, also began to diverge politically and culturally. Although this was a gradual process, still incomplete when Italy came under the rule of barbarian chieftains in the last quarter of the 5th century, it deepened further afterward, and had lasting consequences for the medieval history of Europe.

Throughout the 5th century, Western emperors were usually figureheads, while the Eastern emperors maintained more independence. For most of the time, the actual rulers in the West were military strongmen who took the titles of magister militum, patrician, or both, such as Stilicho, Aetius, and Ricimer. Although Rome was no longer the capital in the West, it remained the West's largest city and its economic center. But the city was sacked by rebellious Visigoths in 410 and by the Vandals in 455, events that shocked contemporaries and signaled the disintegration of Roman authority. Saint Augustine wrote The City of God partly as an answer to critics who blamed the sack of Rome by the Visigoths on the abandonment of the traditional pagan religions.

In June 474, Julius Nepos became Western Emperor but in the next year the magister militum Orestes revolted and made his son Romulus Augustus emperor. Romulus, however, was not recognized by the Eastern Emperor Zeno and so was technically an usurper, Nepos still being the legal Western Emperor. Nevertheless, Romulus Augustus is often known as the last Western Roman Emperor. In 476, after being refused lands in Italy, Orestes' Germanic mercenaries under the leadership of the chieftain Odoacer captured and executed Orestes and took Ravenna, the Western Roman capital at the time, deposing Romulus Augustus. The whole of Italy was quickly conquered, and Odoacer was granted the title of patrician by Zeno, effectively recognizing his rule in the name of the Eastern Empire. Odoacer returned the Imperial insignia to Constantinople and ruled as King in Italy. Following Nepos' death Theodoric the Great, King of the Ostrogoths, conquered Italy with Zeno's approval.

Meanwhile, much of the rest of the Western provinces were conquered by waves of Germanic invasions, most of them being disconnected politically from the East altogether and continuing a slow decline. Although Roman political authority in the West was lost, Roman culture would last in most parts of the former Western provinces into the 6th century and beyond.

The first invasions disrupted the West to some degree, but it was the Gothic War launched by the Eastern Emperor Justinian in the 6th century, and meant to reunite the Empire, that eventually caused the most damage to Italy, as well as straining the Eastern Empire militarily. Following these wars, Rome and other Italian cities would fall into severe decline (Rome itself was almost completely abandoned). Another blow came with the Persian invasion of the East in the 7th century, immediately followed by the Muslim conquests, especially of Egypt, which curtailed much of the key trade in the Mediterranean on which Europe depended.

The Empire was to live on in the East for many centuries, and enjoy periods of recovery and cultural brilliance, but its size would remain a fraction of what it had been in classical times. It became an essentially regional power, centered on Greece and Anatolia. Modern historians tend to prefer the term Byzantine Empire for the eastern, medieval stage of the Roman Empire.

Theories and explanations of the fall

The various theories and explanations of the fall of the Roman Empire in the West can be very broadly classified into four groups, although this classification is not without overlap and does not imply four schools of thought or often more than a superficially similar result of often very different historical analyses:

Explanations attributing the decay to general malaise go back to Edward Gibbon, who argued that the edifice of the Roman Empire had been built on unsound foundations to begin with. According to Gibbon, the fall was – in the final analysis – inevitable. On the other hand, Gibbon had assigned a major portion of the responsibility for the decay to the influence of Christianity, and he is therefore often, though perhaps unjustly, seen as the first proponent of a monocausal explanation.

On the other hand, proponents of a catastrophic collapse are convinced that the fall of the empire was not a pre-determined event and should not be taken for granted. Instead, they are convinced it was due to the combined effect of a number of adverse processes, many of them set in motion by the migration of peoples of the time, and that these processes together applied too much stress on the empire's basically sound structure.

Finally, proponents of transformation as the cause challenge the whole notion of the 'fall' of the empire and distinguish between the fall into disuse of a particular political dispensation,[clarification needed] which was in any case unworkable towards its end, and the fate of the Roman civilisation at the basis of the empire. These explanations are similar enough in reasoning to be considered a school of thought and draw their basic premise from the Pirenne thesis that the Roman world underwent a gradual (though often violent) series of transformations in morphing into the medieval world. The historians belonging to this school often prefer to speak of late antiquity instead of the fall of the Roman Empire.

Decay owing to general malaise

Edward Gibbon

In the words of classicist James J. O'Donnell, the "long, long shadow" of Edward Gibbon "darkens our understanding of the Roman world." Gibbon said the fall of Rome was "the triumph of barbarism and religion."[8] In The History of the Decline and Fall of the Roman Empire (1776–89), Gibbon dated the beginning of the decline of Rome to the year 180 after the death of the emperor Marcus Aurelius.[9] The "long peace" that ended with Marcus, in his view, "introduced a slow and secret poison into the vitals of the empire[10]....The decline of Rome was the natural and inevitable effect of immoderate greatness. Prosperity ripened the principle of decay; the causes of destruction multiplied with the extent of conquest; and as soon as time or accident had removed the artificial supports, the stupendous fabric yielded to the pressure of its own weight."[11] Weakened by internal decay, the Western Roman Empire "was overwhelmed by a deluge of Barbarians."[12]

Gibbon believed that the adoption of Christianity as the religion of Rome in the fourth century was an important factor in the fall of the Empire. He said that Christianity "preached the doctrines of patience and pusillanimity; the active virtues of society were discouraged; and the last remains of the military spirit were buried in the cloister." The Church caused the diversion of money and manpower away from the needs of the Empire.[13] Gibbon was criticized for his linkage of the rise of Christianity with the decline of Rome.[14]

Vegetius on military decline

Writing in the 5th century, the Roman historian Vegetius pleaded for reform of what must have been a greatly weakened army. The historian Arther Ferrill has suggested that the Roman Empire – particularly the military – declined largely as a result of an influx of Germanic mercenaries into the ranks of the legions. This "Germanization" and the resultant cultural dilution or "barbarization" led not only to a decline in the standard of drill and overall military preparedness within the Empire, but also to a decline of loyalty to the Roman government in favor of loyalty to commanders. Ferrill agrees with other Roman historians such as A.H.M. Jones:

...the decay of trade and industry was not a cause of Rome’s fall. There was a decline in agriculture and land was withdrawn from cultivation, in some cases on a very large scale, sometimes as a direct result of barbarian invasions. However, the chief cause of the agricultural decline was high taxation on the marginal land, driving it out of cultivation. Jones is surely right in saying that taxation was spurred by the huge military budget and was thus ‘indirectly’ the result of the barbarian invasion.[15]

Michael Rostovtzeff, Ludwig von Mises, and Bruce Bartlett: excessive government

Historian Michael Rostovtzeff and economist Ludwig von Mises both argued that unsound economic policies played a key role in the impoverishment and decay of the Roman Empire. According to them, in the second and third century AD, the Roman Empire developed a complex market economy in which trade was relatively free. Using Marxist terms, Rostovtzeff in 1926 argued that the roots of Roman decline were the "alliance of the [regressive] elements of the rural proletariat with the military destroyed the beneficient rule of an urban bourgeoisie."[16] Mises in 1959 said the ruin of Rome was due to inflation and government intervention in the economy, especially with price controls that did not reflect market realities.[17] Bruce Bartlett followed in the footsteps of Rostovtzeff and Mises. He titled his 1994 essay, "How Excessive Government Killed Ancient Rome." He said that "the fall of Rome was fundamentally due to economic deterioration resulting from excessive taxation, inflation, and over-regulation."[18]

Joseph Tainter: diminishing returns

In his 1988 book The Collapse of Complex Societies, American anthropologist Tainter presents the view that for given technological levels there are implicit declining returns to complexity, in which systems deplete their resource base beyond levels that are ultimately sustainable. Tainter argues that societies become more complex as they try to solve problems. Social complexity can include differentiated social and economic roles, reliance on symbolic and abstract communication, and the existence of a class of information producers and analysts who are not involved in primary resource production. Such complexity requires a substantial "energy" subsidy (meaning resources, or other forms of wealth). When a society confronts a "problem", such as a shortage of or difficulty in gaining access to energy, it tends to create new layers of bureaucracy, infrastructure, or social class to address the challenge.

For example, as Roman agricultural output slowly declined and population increased, per-capita energy availability dropped. The Romans solved this problem in the short term by conquering their neighbours to appropriate their energy surpluses (metals, grain, slaves, etc.). However, this solution merely exacerbated the issue over the long term; as the Empire grew, the cost of maintaining communications, garrisons, civil government, etc., increased. Eventually, this cost grew so great that any new challenges such as invasions and crop failures could not be solved by the acquisition of more territory. At that point, the Empire fragmented into smaller units.

Though it's often presumed that the collapse of the Roman Empire was a catastrophe for everyone involved, Tainter points out that it can be seen as a very rational preference of individuals at the time, many of whom were better off (all but the elite, presumably). Archeological evidence from human bones indicates that average nutrition improved after the collapse in many parts of the former Roman Empire. Average individuals may have benefited because they no longer had to invest in the burdensome complexity of empire. Tainter's view is supported by later studies which indicate that European men in the medieval period were taller than those of the Roman Empire. Average stature is a good indicator of nutrition and health. [19]

In Tainter's view, while invasions, crop failures, disease or environmental degradation may be the apparent causes of societal collapse, the ultimate cause is diminishing returns on investments in social complexity.[20]

Adrian Goldsworthy

In The Complete Roman Army (2003) Adrian Goldsworthy, a British military historian, sees the causes of the collapse of the Roman Empire not in any 'decadence' in the make-up of the Roman legions, but in a combination of endless civil wars between factions of the Roman Army fighting for control of the Empire. This inevitably weakened the army and the society upon which it depended, making it less able to defend itself against the growing numbers of Rome's enemies. The army still remained a superior fighting instrument to its opponents, both civilized and barbarian; this is shown in the victories over Germanic tribes at the Battle of Strasbourg (357) and in its ability to hold the line against the Sassanid Persians throughout the 4th century. But, says Goldsworthy, "Weakening central authority, social and economic problems and, most of all, the continuing grind of civil wars eroded the political capacity to maintain the army at this level."[21] Goldsworthy set out in greater detail his theory that recurring civil wars during the late fourth and early fifth centuries contributed to the fall of the West Roman Empire (395-476), in his book The Fall of the West: The Slow Death of the Roman Superpower (2009).

Monocausal decay

Disease

William H. McNeill, a world historian, noted in chapter three of his book Plagues and Peoples (1976) that the Roman Empire suffered the severe and protracted Antonine Plague starting around 165 AD. For about twenty years, waves of one or more diseases, possibly the first epidemics of smallpox and measles, swept through the Empire, ultimately killing about half the population. Similar epidemics, such as the Plague of Cyprian, also occurred in the 3rd century. McNeill argues that the severe fall in population left the state apparatus and army too large for the population to support, leading to further economic and social decline that eventually killed the Western Empire. The Eastern half survived due to its larger population, which even after the plagues was sufficient for an effective state apparatus.

Archaeology has revealed that from the 2nd century onward, the inhabited area in most Roman towns and cities grew smaller and smaller. Imperial laws concerning "agri deserti", or deserted lands, became increasingly common and desperate. The economic collapse of the 3rd century may also be evidence of a shrinking population as Rome's tax base was also shrinking and could no longer support the Roman Army and other Roman institutions.

Rome's success had led to increased contact with Asia though trade, especially in a sea route through the Red Sea that Rome cleared of pirates shortly after conquering Egypt. Wars also increased contact with Asia, particularly wars with the Persian Empire. With increased contact with Asia came increased transmission of disease into the Mediterranean from Asia. Romans used public fountains, public latrines, public baths, and supported many brothels all of which were conducive to the spread of pathogens. Romans crowded into walled cities and the poor and the slaves lived in very close quarters with each other. Epidemics began sweeping though the Empire.

The culture of the German barbarians living just across the Rhine and Danube rivers was not so conducive to the spread of pathogens. Germans lived in small scattered villages that did not support the same level of trade as did Roman settlements. Germans lived in single-family detached houses. Germans did not have public baths nor as many brothels and drank ale made with boiled water. The barbarian population seemed to be on the rise. The demographics of Europe were changing.

Economically, depopulation led to the impoverishment of East and West as economic ties among different parts of the empire weakened. Increasing raids by barbarians further strained the economy and further reduced the population, mostly in the West. In areas near the Rhine and Danube frontiers, raids by barbarians killed Romans and disrupted commerce. Raids also forced Romans into walled towns and cities furthering the spread of pathogens and increasing the rate of depopulation in the West. A low population and weak economy forced Rome to use barbarians in the Roman Army to defend against other barbarians.

Environmental degradation

Further information: Deforestation during the Roman period

Another theory is that gradual environmental degradation caused population and economic decline. Deforestation and excessive grazing led to erosion of meadows and cropland. Increased irrigation without suitable drainage caused salinization, especially in North Africa. These human activities resulted in fertile land becoming nonproductive and eventually increased desertification in some regions. Many animal species became extinct.[22] The recent research of Tainter stated that "deforestation did not cause the Roman collapse",[23] although it could be a minor contributing factor.

Also, high taxes and heavy slavery are another reason for decline, as they forced small farmers out of business and into the cities, which became overpopulated. Roman cities were only designed to hold a certain number of people, and once they passed that, disease, water shortage and food shortage became common.[citation needed]

Lead poisoning

See also: Lead poisoning

Publishing several articles in the 1960s, the sociologist S. Colum Gilfillan advanced the argument that lead poisoning was a significant factor in the decline of the Roman Empire.[24][25] Later, a posthumously published book elaborated on Gilfillan's work on this topic.[26] Jerome Nriagu, a geochemist, argued in a 1983 book that "lead poisoning contributed to the decline of the Roman empire." His work centred on the level to which the ancient Romans, who had few sweeteners besides honey, would boil must in lead pots to produce a reduced sugar syrup called defrutum, concentrated again into sapa. This syrup was used to some degree to sweeten wine and food. If acidic must is boiled within lead vessels the sweet syrup it yields will contain a quantity of Pb(C2H3O2)2 or lead(II) acetate.[27] Lead was also leached from the glazes on amphorae and other pottery, from pewter drinking vessels and cookware, and from lead piping used for municipal water supplies and baths.[28]

The role and importance of lead poisoning in contributing to the fall of the Roman Empire is the subject of controversy, and its importance and validity is discounted by many historians.[27] John Scarborough, a pharmacologist and classicist, criticized Nriagu's book as "so full of false evidence, miscitations, typographical errors, and a blatant flippancy regarding primary sources that the reader cannot trust the basic arguments."[29] He concluded that ancient authorities were well aware of lead poisoning and that it was not endemic in the Roman empire nor did it cause its fall. Additionally, Roman authors such as Pliny the Elder[30] and Vitruvius recognised the toxicity of lead.[31]

Catastrophic collapse

J. B. Bury

J. B. Bury's History of the Later Roman Empire (1889/1923) challenged the prevailing "theory of moral decay" established by Gibbon as well as the classic "clash of Christianity vs. paganism" theory, citing the relative success of the Eastern Empire, which was resolutely Christian. He held that Gibbon's grand history, though epoch-making in its research and detail, was too monocausal. His main difference from Gibbon lay in his interpretation of facts, rather than disputing any facts. He made it clear that he felt that Gibbon's thesis concerning "moral decay" was viable—but incomplete. Bury's judgment was that:[32]

The gradual collapse of the Roman power ... was the consequence of a series of contingent events. No general causes can be assigned that made it inevitable.

Bury held that a number of crises arose simultaneously: economic decline, Germanic expansion, depopulation of Italy, dependency on Germanic foederati for the military, the disastrous (though Bury believed unknowing) treason of Stilicho, loss of martial vigor, Aetius' murder, the lack of any leader to replace Aetius—a series of misfortunes which, in combination, proved catastrophic:

The Empire had come to depend on the enrollment of barbarians, in large numbers, in the army, and ... it was necessary to render the service attractive to them by the prospect of power and wealth. This was, of course, a consequence of the decline in military spirit, and of depopulation, in the old civilised Mediterranean countries. The Germans in high command had been useful, but the dangers involved in the policy had been shown in the cases of Merobaudes and Arbogastes. Yet this policy need not have led to the dismemberment of the Empire, and but for that series of chances its western provinces would not have been converted, as and when they were, into German kingdoms. It may be said that a German penetration of western Europe must ultimately have come about. But even if that were certain, it might have happened in another way, at a later time, more gradually, and with less violence. The point of the present contention is that Rome's loss of her provinces in the fifth century was not an "inevitable effect of any of those features which have been rightly or wrongly described as causes or consequences of her general 'decline'". The central fact that Rome could not dispense with the help of barbarians for her wars (gentium barbararum auxilio indigemus) may be held to be the cause of her calamities, but it was a weakness which might have continued to be far short of fatal but for the sequence of contingencies pointed out above.[32]

Peter Heather

Peter Heather, in his The Fall of the Roman Empire (2005), maintains the Roman imperial system with its sometimes violent imperial transitions and problematic communications notwithstanding, was in fairly good shape during the first, second, and part of the 3rd centuries AD. According to Heather, the first real indication of trouble was the emergence in Iran of the Sassanid Persian empire (226–651). In Heather's words:

Much more important to imperial collapse than any internal developments was the rise of Persia to superpower status in the third century AD. From this point on, a much higher proportion of the empire's resources, fiscal and military, had to be focused permanently on the east.[33]...Army, bureaucracy, and politics: all had to adapt in order to meet the Persian challenge.[34]

Heather goes on to state—in the tradition of Gibbon and Bury—that it took the Roman Empire about half a century to cope with the Sassanid threat, which it did by stripping the western provincial towns and cities of their regional taxation income. The resulting expansion of military forces in the Middle East was finally successful in stabilizing the frontiers with the Sassanids, but the reduction of real income in the provinces of the Empire led to two trends which, Heather says, had a negative long-term impact. First, the incentive for local officials to spend their time and money in the development of local infrastructure disappeared. Public buildings from the 4th century onward tended to be much more modest and funded from central budgets, as the regional taxes had dried up. Second, Heather says "the landowning provincial literati now shifted their attention to where the money was ... away from provincial and local politics to the imperial bureaucracies."[35] Having set the scene of an Empire stretched militarily by the Sassanid threat, Heather then suggests, using archaeological evidence, that in 400 CE the Germanic tribes of Europe had "increased substantially in size and wealth" since the first century. Contact with the Empire had increased their material wealth, and that in turn had led to disparities of wealth sufficient to create ruling and military classes capable of maintaining control over far larger groupings than had previously been possible. The Germans had become more formidable foes.[36]

Heather then posits what amounts to a domino theory—namely that pressure on peoples very far away from the Empire could result in sufficient pressure on peoples on the Empire's borders to make them contemplate the risk of full scale immigration to the empire. Thus he links the Gothic invasion of 376 directly to Hunnic movements around the Black Sea in the decade before. In the same way he sees the invasions across the Rhine in 406 as a direct consequence of further Hunnic incursions in Germania; as such he sees the Huns as important in the fall of the Western Empire long before they themselves became a military threat to the Empire. He postulates that the Hunnic expansion caused unprecedented invasions of the Empire in 376 and 405-408 by barbarian groupings who had become significantly more politically and militarily capable than in previous eras. This detached territory and denied revenues to an empire already at maximum stretch due to the Sassanid pressure.[37]

He disputes Gibbon's contention that Christianity and moral decay led to the decline. He also rejects the political infighting of the Empire as a reason, considering it was a systemic recurring factor throughout the Empire's history which, while it might have contributed to an inability to respond to the challenges of the 5th century, it cannot be blamed for them. Instead he places the fall of the Western Roman Empire on outside military factors, starting with the Sassanids, and ending with the Germanic invasions under pressure from the Huns.[38]

Bryan Ward-Perkins

Bryan Ward-Perkins's The Fall of Rome and the End of Civilization (2005) takes a traditional view tempered by modern discoveries, arguing that the empire's demise was caused by a vicious circle of political instability, foreign invasion, and reduced tax revenue. Essentially, invasions caused long-term damage to the provincial tax base, which lessened the Empire's medium- to long-term ability to pay and equip the legions, with predictable results. Likewise, constant invasions encouraged provincial rebellion as self-help, further depleting Imperial resources. Contrary to the trend among some historians of the "there was no fall" school, who view the fall of Rome as not necessarily a "bad thing" for the people involved, Ward-Perkins argues that in many parts of the former Empire the archaeological record indicates that the collapse was truly a disaster.

Ward-Perkins' theory, much like Bury's, and Heather's, identifies a series of cyclic events that came together to cause a definite decline and fall.

Transformation

Henri Pirenne

In the second half of the 19th century, some historians focused on the continuities between the Roman Empire and the post-Roman Germanic kingdoms rather than the rupture. In Histoire des institutions politiques de l'ancienne France (1875–89), Fustel de Coulanges argued that the barbarians simply contributed to an ongoing process of transforming Roman institutions.

Henri Pirenne continued this idea with the "Pirenne Thesis", published in the 1920s, which remains influential to this day. It holds that even after the barbarian invasions, the Roman way of doing things did not immediately change; barbarians came to Rome not to destroy it, but to take part in its benefits, and thus they tried to preserve the Roman way of life. The Pirenne Thesis regards the rise of the Frankish realm in Europe as a continuation of the Roman Empire, and thus validates the crowning of Charlemagne as the first Holy Roman Emperor as a successor of the Roman Emperors. According to Pirenne, the real break in Roman history occurred in the 7th and 8th centuries as a result of Arab expansion. Islamic conquest of the area of today's south-eastern Turkey, Syria, Palestine, North Africa, Spain and Portugal ruptured economic ties to western Europe, cutting the region off from trade and turning it into a stagnant backwater, with wealth flowing out in the form of raw resources and nothing coming back. This began a steady decline and impoverishment so that by the time of Charlemagne western Europe had become almost entirely agrarian at a subsistence level, with no long-distance trade. Pirenne's view on the continuity of the Roman Empire before and after the Germanic invasion has been supported by recent historians such as François Masai, Karl Ferdinand Werner, and Peter Brown.

Some modern critics have argued that the "Pirenne Thesis" erred on two counts: by treating the Carolingian realm as a Roman state and by overemphasizing the effect of the Islamic conquests on the Byzantine or Eastern Roman Empire. Other critics have argued that while Pirenne was correct in arguing for the continuity of the Empire beyond the sack of Rome, the Arab conquests in the 7th century may not have disrupted Mediterranean trade routes to the degree that Pirenne argued. Michael McCormick in particular has argued that some recently unearthed sources, such as collective biographies, describe new trade routes. Moreover, other records and coins document the movement of Islamic currency into the Carolingian Empire. McCormick has concluded that if money was coming in, some type of goods must have been going out – including slaves, timber, weapons, honey, amber, and furs.

Lucien Musset and the clash of civilizations

In the spirit of "Pirenne thesis", a school of thought pictured a clash of civilizations between the Roman and the Germanic world, a process taking place roughly between 3rd and 8th century.

The French historian Lucien Musset, studying the Barbarian invasions, argues the civilization of Medieval Europe emerged from a synthesis between the Graeco-Roman world and the Germanic civilizations penetrating the Roman Empire. The Roman Empire did not fall, did not decline, it just transformed but so did the Germanic populations which invaded it. To support this conclusion, beside the narrative of the events, he offers linguistic surveys of toponymy and anthroponymy, analyzes archaeological records, studies the urban and rural society, the institutions, the religion, the art, the technology.

Late Antiquity

Historians of Late Antiquity, a field pioneered by Peter Brown, have turned away from the idea that the Roman Empire fell at all – refocusing instead on Pirenne's thesis. They see a transformation occurring over centuries, with the roots of Medieval culture contained in Roman culture and focus on the continuities between the classical and Medieval worlds. Thus, it was a gradual process with no clear break. Brown argues in his book that:

Factors we would regard as natural in a 'crisis'—malaise caused by urbanization, public disasters, the intrusion of alien religious ideas, and a consequent heightening of religious hopes and fears—may not have bulked as large in the minds of the men of the late second and third centuries as we suppose... The towns of the Mediterranean were small towns. For all their isolation from the way of life of the villagers, they were fragile excrescences in a spreading countryside."[39]
