The historians' history of the world in twenty-five volumes, volume 07

In Short

This volume surveys the chaotic, majestic lifespan of the Later Roman Empire, tracking its evolution from the barbarian incursions of the fifth century through the fall of Constantinople and the dawn of the Middle Ages. Synthesized from dozens of classical and modern historians—including Gibbon, Procopius, Ammianus, and Bury—the narrative charts how a unified superpower splintered under the weight of internal rot, fiscal extortions, and external pressure from Goths, Huns, Saracens, and Franks. Empires collapse not in a single dramatic stroke, but through an endless cycle of palace coups, religious schisms, and structural decay, counterbalanced by brief flashes of military genius and administrative reform. Through chronological summaries, detailed campaign accounts, and institutional analyses, the work illustrates the resilience of imperial governance alongside the inevitable rise of new European nationalities. It has endured because it aggregates the vast spectrum of primary accounts into a unified, authoritative, and deeply human tapestry of human ambition and institutional decline.

The Story

The narrative opens with the early fractures of the Roman world as migrating tribes tested the empire’s borders. In Greece and Attica, the Gothic leader Alaric marches through the provinces, levying heavy contributions, plundering Eleusis, and driving civic authorities into capitulation. While legend claims supernatural apparitions spared Athens, the historical reality is one of political expediency, wall fortifications, and calculated ransoms. Farther east, nomadic hordes reshape the geopolitics of the ancient world. The Huns under Attila, compared by historical authorities to the later Mongol armies of Jenghiz Khan and Tamerlane, depopulate whole provinces through mass captivity, systemic rapine, and relentless raids, driving thousands into servitude and uprooting established civic structures.

Within Constantinople, the imperial core struggles against its own fiscal and moral corruption. Under Justinian, the empire achieves spectacular territorial expansions, but at immense human and economic cost. Imperial treasurers establish trade monopolies, such as the total seizure of silk manufacturing in Tyre and Berytus, driving entire populations into destitution or flight to rival Persia. The direct sale of public offices and judicial honors in the imperial palace creates a predatory bureaucracy where officials exact exorbitant fees from citizens to recoup the price of their appointments. Though Justinian occasionally attempts to curb this corruption with legal edicts and solemn oaths, the edicts are quickly suspended, leaving venality triumphant.

Simultaneously, Justinian pursues aggressive military campaigns to reclaim lost Western provinces. He concludes an costly "Everlasting Peace" with the Persian king Chosroes by paying eleven thousand pounds of gold, freeing military assets to attack the Vandals and Visigoths. Yet this peace proves brief; Chosroes, jealous of Justinian’s Western conquests, breaks the treaty, invades Syria, sacks Antioch, and carries its population into captivity. In Europe, the Visigoth king Theudes fails to unite with the Vandals, allowing imperial forces to seize strategic coastal strongholds in Spain that remain occupied for seventy years.

Across the centuries, external rivalries intensify. The Sassanian Empire undergoes internal collapse when the Persian ruler Hormuz, after insulting his victorious general Bahram by sending him women's clothing, faces a military revolt. Hormuz is deposed and imprisoned by the noble Bindoes. Decades later, the emperor Heraclius achieves monumental triumphs over Persia, reclaiming the True Cross and restoring it to Jerusalem. Yet his victories leave the empire financially ruined and physically exhausted. The state is forced to tax its devastated provinces a second time to repay war debts owed to the church. Weakened by these conflicts, the empire is caught unprepared when the forces of Islam emerge from the Arabian peninsula, permanently seizing the very provinces Heraclius had just rescued.

Internal instability continues to tear at the state. Dynasties rise and fall through brutal intrigue: Leontius overthrows Justinian II, mutilating his nose and exiling him to Cherson, only to lose Africa and Carthage to Arab forces due to naval mismanagement and civil neglect. In the palace, empresses like Irene seize power, blinding their own sons to hold the throne, while religious conflicts over image-worship tear the social fabric apart.

In the West, barbarian kingdoms evolve into new political powers. Clovis and his Franks invoke religious zeal to drive the Arian Visigoths from Gaul, aided by local Catholic bishops. Charles Martel halts the Saracen advance at Poitiers, securing his borders and laying the groundwork for the Carolingian dynasty. His grandson Charlemagne subjugates the Saxons through brutal campaigns—including the execution of 4,500 prisoners at Verden—and institutes deep structural reforms that reshape European society.

As the centuries progress, eastern borders face new threats from the Varangians and Russians. The emperor Joannes Zimisces besieges Sviatoslaff at Dorystolon, engaging in desperate battles until a hard-fought peace allows the defeated Russian forces to return home. Alexius Comnenus navigates the incoming wave of Western Crusaders with shrewd diplomacy, but the Western powers eventually turn on Byzantium. In 1204, the Fourth Crusade sacks Constantinople, partition the imperial lands, and puts whole provinces up for auction among Western knights. Though Michael Palæologus briefly restores the Greek empire in 1261—blinding his young co-emperor Joannes IV to secure his usurpation—the empire never recovers its former strength.

The final chapters chronicle the agonized decline under the Ottoman shadow. Emperor Manuel II embarks on a humiliating pilgrimage to Western Europe begging for aid, receiving polite charity but little military support. Though Timur’s crushing defeat of Sultan Bajazet at Angora briefly grants Byzantium a respite, the Ottoman state rapidly reconstitutes itself. Sultan Muhammed II systematically reduces the remaining Christian enclaves, demanding total submission from rulers like David Comnenus of Trebizond and Demetrius Palæologus of the Morea. Striped of power, former emperors end their days in exile on papal pensions or isolated in monastic cells, bringing a thousand-year imperial narrative to its quiet, definitive end.

How It Unfolds

The barbarian tide surges Alaric marches his Gothic host through Greece, imposing heavy financial levies on Athens and destroying Eleusis. Simultaneously, Attila’s Huns sweep across imperial territories, capturing thousands of citizens and depopulating vast regions through systematic destruction.

Justinian’s grand ambition The emperor Justinian enforces state trade monopolies and legalizes the sale of public offices, straining the empire’s economy. He purchases a temporary peace with Persia to launch military campaigns aimed at reclaiming lost Western provinces in Italy and Spain.

Persian rivalries and ruin Sassanian king Hormuz insults his general Bahram, sparking a military revolt that leads to Hormuz’s imprisonment by the noble Bindoes. Later, Emperor Heraclius defeats Persia and restores the True Cross to Jerusalem, but the ruinous cost leaves the empire vulnerable to rapid Saracen conquests.

Dynastic violence and lost provinces Leontius dethrones Justinian II, cutting off his nose and exiling him, but soon loses Carthage and North Africa to Arab fleets due to administrative negligence. In Constantinople, Empress Irene blinds her son Constantine VI to seize sole control of the empire amid fierce iconoclastic disputes.

The rise of Frankish hegemony Clovis rallies Catholic support to defeat the Visigoths in Gaul, while Charles Martel halts Saracen expansion at the Battle of Poitiers. Charlemagne forcefully consolidates Western Europe, brutally quelling the Saxon rebellion under Witikind and establishing a vast, reformed empire.

Carolingian fracture and northern raids Charlemagne's heirs turn on one another, leading to civil wars between Lothair, Ludwig the German, and Charles the Bald. Taking advantage of internal division, Norse raiders ravage imperial territories until King Arnulf defeats them in a hand-to-hand battle near Lyons.

Byzantine struggle and imperial collapse Emperor Joannes Zimisces repels the Russian forces under Sviatoslaff at the Siege of Dorystolon, securing a temporary treaty. Centuries later, Western knights of the Fourth Crusade capture Constantinople, partitioning imperial lands and selling off whole cities among themselves.

The final Ottoman conquest Emperor Manuel II travels to Western Europe begging for military aid against the Ottomans, but returns with little support. Sultan Muhammed II systematically absorbs the remaining imperial remnants, forcing rulers like David Comnenus and Demetrius Palæologus into exile or execution.

The People

• Alaric: The ambitious Gothic king who leads his armies through Greece. Seeking plunder and political concessions, he spares Athens through a negotiated capitulation while razing surrounding towns like Eleusis.
• Attila: The formidable ruler of the Huns whose widespread raids depopulate Roman provinces. He governs a vast pastoral horde that exacts massive human captivity and destruction across both Eastern and Western empires.
• Justinian: The determined Eastern Roman Emperor who attempts to restore the glory of the Western Empire. He codifies laws and expands borders, but relies on oppressive monopolies and the sale of public offices to fund his costly wars.
• Heraclius: The resilient Byzantine emperor who saves the empire from Persian destruction and returns the True Cross to Jerusalem. Despite his military genius, his reign ends in tragedy as financial exhaustion causes the rapid loss of his conquered lands to Arab armies.
• Hormuz: The arrogant Sassanian king of Persia whose erratic cruelty alienates his court. After humiliating his victorious general Bahram with female clothing, he is overthrown by the noble Bindoes and thrown into a dungeon.
• Bindoes: A courageous Sassanian prince who escapes his imprisonment to lead a palace coup. He personally confronts and deposes King Hormuz, placing him in the same cell he recently occupied.
• Irene: The ambitious Athenian-born empress who restores image-worship to the Greek Church. Driven by a relentless desire for power, she suppresses her son Constantine VI and eventually has him blinded to rule as sole emperor.
• Clovis: The cunning king of the Franks who unifies his nation under Catholic Christianity. He uses religious zeal to justify his wars against the Arian Visigoths, expanding Frankish dominion across Gaul.
• Charlemagne: The powerful Frankish monarch who builds a vast Western empire through decades of relentless military campaigning. He forcefully converts and subjugates the Saxons under Witikind while reforming legal and cultural institutions.
• Witikind: The resilient Saxon chieftain who leads a fierce pagan resistance against Charlemagne's expansion. He repeatedly rallies his people to defend their traditional rights until forced into flight and ultimate submission.
• Michael Palæologus: The calculating Byzantine noble who usurps the imperial throne and recaptures Constantinople from the Latins. To secure his rule, he orders the blinding and lifelong imprisonment of his ten-year-old ward, Joannes IV.
• Muhammed II: The decisive Ottoman sultan who completes the destruction of the Byzantine Empire. He systematically demands the surrender of remaining Greek enclaves, forcing their last rulers into exile or execution.

In Its Own Voice

"As soon as the exclusive sale of silk was usurped by the imperial treasurer, a whole people, the manufacturers of Tyre and Berytus, was reduced to extreme misery, and either perished with hunger, or fled to the hostile dominions of Persia."

This passage illustrates the devastating domestic consequences of Justinian's fiscal monopolies, where state control of key industries ruined local economies and forced taxpayers into foreign exile.

"The loss of two hundred thousand soldiers who had fallen by the sword, was of less fatal importance than the decay of arts, agriculture, and population, in this long and destructive war: and although a victorious army had been formed under the standard of Heraclius, the unnatural effort appears to have exhausted rather than exercised their strength."

Here, the text highlights the hollow nature of Heraclius's victory over Persia, showing how the total economic and human exhaustion of the state paved the way for immediate foreign conquest.

"In the distribution of the cities and lands of the empire, every one of the lords and barons had obtained domains proportionate with the rank and services of the new possessor."

This comment captures the mercenary reality of the Fourth Crusade, wherein Western invaders carved up the ancient Byzantine realm as personal spoils of war.

What It's Really About

At its core, this volume explores the fundamental fragility of civilizational power and the structural causes of imperial decline. Through a century-spanning survey, the text argues that states rarely collapse purely from external conquest; rather, foreign invaders merely shatter structures that have already been hollowed out from within. The repeated collapse of Roman and Byzantine authority is consistently traced back to domestic corruption: fiscal extortion by state treasurers, the sale of judicial and administrative offices, and the willingness of ruling elites to betray the public good for immediate personal wealth.

The text also examines the powerful interplay between religious ideology and political legitimacy. Religious zeal acts as both a unifying force for emerging kingdoms—such as Clovis using Catholic orthodoxy to conquer Gaul—and a deeply destructive wedge within established states, where bitter schisms over iconoclasm or doctrine distract rulers from pressing border threats.

Furthermore, the narrative highlights the relentless cycle of human ambition. Victory over a rival power frequently breeds a fatal overextension, exhausting the state’s human and financial capital. Time and again, great military leaders like Heraclius achieve brilliant triumphs only to leave their nations too depleted to survive the next political wave. Civilization is presented not as a static achievement, but as an endless, precarious balance between administrative order and the chaotic forces of human greed and ambition.

Why Read It Today

This volume offers a sweeping, unvarnished look at the mechanics of institutional decay and geopolitical transformation. Readers who enjoy big-picture history will appreciate the seamless integration of classic texts into a single, continuous narrative that spans centuries of European and Eastern history. It provides an extraordinary view of how global power shifts over long periods, offering valuable perspective on how modern states handle fiscal overextension, border defense, and internal division.

The experience of reading it is like walking through a vast historical gallery filled with vivid character studies, dramatic reversals of fortune, and sharp political analysis. Rather than presenting history as a series of dry dates, the text brings to life the stark human choices behind major historic events: a general insulted by his king, an empress plotting against her son, or a defeated emperor begging for money in foreign courts.

However, readers should be prepared for certain period difficulties. The narrative moves at a relentless pace across vast geographic regions, requiring attention to complex political lines and shifting regional names. Furthermore, because the volume relies on early 20th-century scholarship and classic texts, it reflects the period attitudes of its source historians—including moralizing judgments on Eastern politics, harsh portrayals of barbarian tribes, and occasional outdated historical spellings. Yet for those willing to engage with its grand scale and elevated prose style, the book remains a deeply rewarding study of power, ambition, and the impermanence of empires.
