The Biggest Mistakes That Destroyed Great Empires

What separates a great empire from a cautionary tale? Lucas and Luna dissect the critical moments when power, pride, and poor decisions turned dominance into dust. From the overexpansion of the Roman Empire that strained its borders and economy, to the administrative collapse of the Mauryan Empire after Ashoka's pacifist turn, to the Ming Dynasty's disastrous maritime withdrawal under the Hongwu Emperor — each episode examines a single 'mistake' that accelerated decline. We explore the Battle of Adrianople (378 CE) where Gothic victories exposed Rome's brittle defenses; the catastrophic Mongol invasion of Japan thwarted by typhoons but also by strategic missteps; the Inca civil war that paved the way for Pizarro's conquest; and the Aztec reliance on tributary states that bred resentment. Along the way, we question whether 'mistakes' are inevitable in cycles of power, or whether leaders like Cleopatra, Napoleon, and Hitler simply made choices that sealed their fates. Through trade policies, military overreach, succession crises, and cultural arrogance, we trace how empires from Persia to Britain stumbled. The show doesn't just chronicle fall — it asks what we can learn today about institutional rigidity, hubris, and the silence before collapse.

The Sassanid Army's Fatal Flaw: Ghost Units and Empty Ranks

Aug 15, 2026 · 7:39

By the time Yazdegerd III faced the Arab armies at al-Qadisiyyah and Nihawand, the Sassanid military machine was a hollow shell. This episode digs into the quiet rot: a pay system that rewarded noble birth over competence, a cavalry elite that hoarded the best horses and gear, and a peasant infantry so neglected it barely counted. We follow the money—from the great spahbed commands to the local dehqan landlords—and see how the savaran became a privileged club while the empire's real strength…

The Sassanid Mistake That Lost the Crown Prince

Aug 14, 2026 · 8:28

In this milestone episode, Lucas and Luna explore the disastrous flight of the last Sassanid heir, Peroz III, to Tang China. After the fall of Ctesiphon and the death of Yazdegerd III at Merv, Peroz sought refuge at the court of Tang Gaozong, hoping to reclaim his father's throne. They trace his journey across Khorasan, his reception in Chang'an, and the Tang court's decision to support him. Drawing on the Old Book of Tang and the accounts of al-Tabari, they unpack the political calculations…

The Sassanid Mistake That Lost the Royal Banner

Aug 13, 2026 · 6:38

In Episode 199, Lucas and Luna explore the fall of the Sassanid Empire through the story of the Derafsh Kaviani, the royal banner that symbolized Persian kingship for centuries. From its legendary origins in the mythical past to its capture at the Battle of al-Qadisiyyah in 636 CE, the banner's fate mirrored the empire's decline. Lucas unpacks how the banner was woven from the apron of a blacksmith named Kaveh, why it carried jewels and a star, and how its loss at the hands of the Muslim Arabs…

The Sassanid Mistake That Lost the Crown of Glory

Aug 12, 2026 · 8:18

In this episode, Lucas and Luna explore a turning point that is often overlooked in the story of Persia's fall: the moment when the Sassanid kings traded the ancient khwarrah for a crown of gold and conquest. They trace the concept of divine glory from the Avestan hymns to the investiture reliefs at Naqsh-e Rostam, and they show how Ardashir I and Shapur I understood it, how Khosrow II gambled it away in his wars with Byzantium, and how Yazdegerd III lost it for good on the road to Merv. Along…

The Sassanid Mistake That Broke the Royal Succession

Aug 11, 2026 · 11:09

In this episode, Lucas and Luna revisit the final decades of the Sassanid Empire to uncover a quiet, fatal flaw: a succession system that turned every royal death into a civil war. From the murder of Hormizd IV to the fratricidal bloodbath under Khosrow II, the crown became a prize for the highest bidder among the wuzurgan, the great nobles. We follow the rise of Shahrbaraz, the general who seized the throne and lost it within months, and the desperate crowning of the child-king Yazdegerd III…

The Sassanid Mistake That Let the Hephthalites In

Aug 10, 2026 · 11:00

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a lesser-known but pivotal error of the late Sassanid Empire: the failure to secure the northeastern frontier against the Hephthalites. While earlier episodes covered military defeats and economic collapse, this one zeroes in on how the Sassanids' repeated wars with the Hephthalites—fought over and around the Silk Road—bled the empire dry and left it exposed to a new threat from the east. Lucas walks…

The Sassanid Mistake of the Coronation Oath

Aug 9, 2026 · 7:18

In this episode of Fexingo History, Lucas and Luna explore the Sassanid coronation oath — a sacred promise made by each new shahanshah to protect the realm and uphold the faith. They trace its origins to Ardashir I and examine how later kings, especially Khosrow II, broke it, draining the khwarrah — the divine glory that legitimized Sassanid rule. The episode covers the oath's role in the succession crisis of Kavad I and Mazdak, the reforms of Khosrow I, and the final, desperate reign of…

The Sassanid Mistake of the Coronation Oath

Aug 8, 2026 · 7:33

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a lesser-known but fatal flaw in Sassanid Persia: the coronation oath. When a new king took the throne at Ctesiphon, he swore to uphold the pact between crown, altar, and landed nobility. But in the disastrous reign of Kavad I, that oath collided with the reformer Mazdak and his radical message of communal property. The result was a decade of chaos that nearly tore the empire apart before Khosrow I…

The Sassanid Mistake: When the Royal Hunt Went Wrong

Aug 7, 2026 · 9:48

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore the Sassanid royal hunt — a tradition that was far more than sport. For centuries, the shahs of Persia used the hunt as a stage for power, a training ground for the savaran elite, and a way to bind the nobility to the throne. But when the institution decayed, it became a symbol of the dynasty's decline. Drawing on the Shahnameh, the carvings at Taq-e Bostan, and the accounts of al-Tabari, the hosts…

The Sassanid Mistake That Starved Ctesiphon of Grain

Aug 6, 2026 · 8:18

In this episode, Lucas and Luna explore how the Sassanid Empire's fatal neglect of its own agricultural heartland in Khuzestan contributed to its collapse before the Arab conquests. Focusing on the Great Kavir salt desert and the qanat irrigation systems that sustained the empire, they discuss how Khosrow II's over-taxation and the subsequent breakdown of water management led to famine and desertification. The episode draws on inscriptions from the Naqsh-e Rostam and the writings of al-Tabari…

The Sassanid Mistake That Lost the Royal Road

Aug 5, 2026 · 8:50

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore the Sassanid Empire's fatal neglect of its own legendary road network. From the stone-paved highways that once linked Ctesiphon to the Silk Road's western terminus, to the caravanserais that fell into ruin as local strongmen took over, we trace how a crumbling infrastructure quietly eroded imperial control. We look at the Royal Road's Persian roots, the Sassanid upgrades that made it the envy of the…

The Fire Temple That Fueled an Empire and Its Fall

Aug 4, 2026 · 7:45

In this episode of The Biggest Mistakes That Destroyed Great Empires, we look at the role of Zoroastrian fire temples in Sassanid Persia's collapse. While earlier episodes touched on the faith's institutions, we now focus on how the crown's alliance with the mobadhan—the Zoroastrian clergy—turned sacred flames into instruments of control and, ultimately, alienation. We follow the story of Adur Gushnasp, the great warrior fire at Shiz, and how its association with the shahanshah made it a target…

The Sassanid Mistake That Left the Eastern Gates Unguarded

Aug 3, 2026 · 7:32

In episode 189, Lucas and Luna turn eastward to the Khorasan front, where the Sassanid Empire's failure to secure its northeastern marches against the Hephthalites and Türgesh opened the way for the Rashidun Caliphate's swift conquest. They explore the strategic importance of the Silk Road oasis towns—Merv, Balkh, Nishapur—and the role of the dihqans, the local landed gentry whose loyalty was stretched thin by a distant court in Ctesiphon. How did a series of missteps, including the neglect of…

The Sassanid Mistake That Blinded the Desert Watchtowers

Aug 2, 2026 · 4:22

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna trace how a chain of small stone watchtowers along the Silk Road failed to save Sassanid Persia. The towers, linked by signal fires from Merv to Ctesiphon, were meant to give early warning of steppe raids and nomad incursions. But by the 620s, neglect, cost-cutting, and a focus on the Byzantine front left many unmanned. When the Rashidun armies swept out of Arabia, the network that should have flashed warnings…

The Sassanid Mistake That Lost the Silk Road

Aug 1, 2026 · 4:38

In this episode, Lucas and Luna explore how the Sassanid Empire's catastrophic mismanagement of the Silk Road trade — marked by the murder of the last great king, the disruption of the northern routes, and the rise of the Türgesh and Khazar powers — directly contributed to its collapse. Drawing on the accounts of al-Tabari and the Old Book of Tang, they trace the empire's fatal reliance on the Sogdian merchants, the closure of the vital Kharazmian corridor, and the fateful decision to redirect…

Sassanid Spahbeds: The Military Mistake That Toppled the Throne

Jul 30, 2026 · 5:44

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore how the Sassanid Empire's own military structure—the spahbed system—became a fatal liability. Created by Khosrow I to command the four quarters of the realm, the spahbeds (supreme generals) evolved into autonomous warlords who prioritized personal ambition over imperial unity. We trace the rebellions of Bahram Chobin (from the House of Mihran), the brief coup of Shahrbaraz after Khosrow II's downfall…

Nihawand 642 The Battle That Ended Sassanid Persia

Jul 30, 2026 · 6:13

After the defeat at al-Qadisiyyah, the Sassanid Empire was reeling. Yazdegerd III fled Ctesiphon, but he still commanded vast resources from the eastern provinces. In 642 CE, Persian forces gathered at Nihawand to make a final stand against the advancing Rashidun army. This episode explores the fatal strategic errors that led to the Sassanid defeat at Nihawand: overconfidence in open battle, underestimation of Arab tactical flexibility, and a failure to adapt to guerrilla warfare. We examine…

The Sassanid Mistake at al-Qadisiyyah: Overconfidence Lost an Empire

Jul 29, 2026 · 5:02

In 636 CE, on the plains of southern Iraq, the Sassanid Empire faced a new threat: the armies of the Rashidun Caliphate. Exhausted by decades of war with Byzantium and plagued by internal decay, the Persians under Yazdegerd III thought they could crush the Arab invaders with a single decisive battle. But at al-Qadisiyyah, the Sassanid commander Rustam Farrokhzad made a series of fatal errors — from overreliance on heavy cavalry to underestimating Bedouin mobility and failing to coordinate with…

The Sassanid Mistake That Dried Up Mesopotamia's Canals

Jul 29, 2026 · 5:18

The Sassanid Empire didn't fall solely on the battlefield — it was slowly undermined by the collapse of its ancient water infrastructure. In this episode, Lucas and Luna explore the catastrophic neglect of the Tigris-Euphrates irrigation system, once the agricultural backbone of Persia. They trace the golden age of canals under Khosrow I, the engineering marvel of the Nahrawan Canal, and how short-sighted rulers after him let the qanats silt up, fields salinize, and tax revenues vanish. The…

Khosrow II's Overreach: How the Byzantine War Destroyed Sassanid Persia

Jul 28, 2026 · 6:10

In 602 AD, the murder of Byzantine Emperor Maurice gave Khosrow II a pretext for war—a war of revenge that would ultimately doom his own empire. This episode explores the miscalculations that turned a string of stunning Persian victories into a catastrophic defeat. From the capture of Jerusalem and the True Cross to the failed siege of Constantinople with the Avars, we trace how Khosrow's refusal to negotiate, his alienation of the brilliant general Shahrbaraz, and his overreach led to…

The General Who Broke the Sassanid Throne: Bahram Chobin's Rebellion

Jul 28, 2026 · 7:23

In the dying years of the 6th century, the Sassanid Empire tore itself apart from within. This episode focuses on the rebellion of Bahram Chobin, a celebrated spahbed (general) who, after being humiliated by his king, marched on Ctesiphon, overthrew the monarchy, and briefly ruled as Shahanshah. Lucas and Luna trace how this civil war drained the empire's military elite, alienated loyalist clans, and invited Byzantine intervention—setting the stage for the rapid collapse just decades later.…

The Last Sassanid Prince in Tang China: Peroz III's Impossible Dream

Jul 27, 2026 · 5:35

After the Arab conquest of Persia, Yazdegerd III's son Peroz III fled east to the Tang court in Chang'an. There, Emperor Gaozong granted him a government in exile and military support for a doomed attempt to reclaim the Sassanid throne. This episode follows Peroz's journey along the Silk Road, his alliance with the Turks of Tokharistan, and the eventual absorption of the Persian diaspora into Tang society. Drawing on Chinese chronicles like the Old Book of Tang, we explore how the last Emperor…

The Sassanid Mistake That Unleashed the Mazdakite Crisis

Jul 27, 2026 · 6:57

Kavad I's support for the radical Mazdakite movement in the 5th-6th centuries nearly tore the Sasanian Empire apart. This episode explores how the king's alliance with a firebrand preacher led to the redistribution of wealth, the fall of noble families, and a violent backlash that culminated in a bloody purge by Khosrow I. We trace the story from Kavad's deposition to his return, the Council of Ctesiphon, and the lasting damage done to the empire's social fabric—a fissure that would reopen…

The Sassanid Mistake That Lost the Dihqan Loyalty

Jul 26, 2026 · 5:20

In this episode, Lucas and Luna explore the fatal internal division that crippled the Sassanid Empire from within: the alienation of the dihqan class. These local landholders and petty aristocrats had long formed the backbone of Persian administration and military recruitment. But as the empire's central authority weakened under Khosrow II and his successors, the dihqans were increasingly squeezed by heavy taxation and neglect. When the Arab armies crossed into Iran, many dihqans chose to…

The Sassanid Mistake That Destroyed the Lakhmid Buffer

Jul 26, 2026 · 6:08

In this episode, Lucas and Luna explore one of the Sassanid Empire's most self-inflicted wounds: the decision to dismantle the Lakhmid buffer kingdom in 602 AD. For centuries, the Lakhmids of Hira had guarded Persia's Arabian frontier, keeping Bedouin raids at bay and maintaining a delicate balance of alliances. But when Khosrow II suspected the last Lakhmid king, al-Nu'man III, of disloyalty, he arrested him and abolished the kingdom—a move that alienated powerful Arab tribes like the Banu…

Sassanid Persia's Fatal Mistake: Debasement of the Silver Drachm

Jul 25, 2026 · 6:07

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore how the Sassanid Empire's gradual debasement of its silver coinage under Khosrow II and his successors poisoned the economy from within. They trace how centuries of reliable drachm weight gave way to inflation, hoarding, and loss of trust among the dihqan landholders and savaran cavalry, ultimately crippling the empire's ability to pay troops and maintain loyalty. This economic self-inflicted wound…

The Sassanid Mistake That Lost the Gorgan Wall

Jul 24, 2026 · 4:09

In this episode, Lucas and Luna explore the Sassanid Empire's catastrophic failure to maintain the Gorgan Wall, the longest defensive barrier of its time. Built under Khosrow I in the 6th century, this 195-kilometer wall across northeastern Iran was meant to hold back the Hephthalites and later the Türgesh and Khazar nomads. But after the devastating war with Byzantium and the plague of 628, the Sassanids could no longer garrison the wall. Lucas explains how the dehqan landowners, once the…

The Sassanid Mistake: Ignoring the Caucasus Defensive Line

Jul 24, 2026 · 5:48

Why did the Sassanid Empire, for all its military might, repeatedly fail to secure its northern frontier in the Caucasus? This episode explores the strategic blunder of neglecting the Derbent Pass and the fortifications of the Caucasus Mountains against nomadic incursions. Lucas and Luna discuss the Khazar khaganate's rise, the 7th-century raids that ravaged Persian provinces, and the empire's disastrous decision to redirect crack troops from the north to fight Byzantium. Key figures like…

Sassanid Persia's Fatal Mistake The Overlooked Role of the Zoroastrian Fire Temples

Jul 23, 2026 · 3:56

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a lesser-known but critical factor in the collapse of the Sassanid Empire: the systematic neglect and alienation of the Zoroastrian fire temples. As the empire faced existential threats from the Rashidun Caliphate, the central government's failure to maintain the sacred fires—especially the Adur Gushnasp, Adur Farnbag, and Adur Burzen-Mihr—eroded religious legitimacy and local support. We delve into how…

The Sassanid Mistake: Alienating the Armenian Allies

Jul 23, 2026 · 6:46

In the final decades of the Sassanid Empire, a critical error cost them their most loyal buffer state: Armenia. This episode of The Biggest Mistakes That Destroyed Great Empires explores how Khosrow II's suspicion of his Christian Armenian nobles led to the catastrophic Battle of Avarayr and the eventual collapse of the eastern frontier. We examine the role of the sparapet, the Mamikonian and Bagratuni houses, the Zoroastrian imposition of the mowbedan mowbed, and the lasting damage to Sassanid…

The Sassanid Mistake That Drained Their Treasury: Khosrow II's Gold

Jul 22, 2026 · 7:12

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a lesser-known but catastrophic error of the Sassanid Empire: the reckless accumulation and hoarding of gold under Khosrow II. After decades of war with Byzantium, the shah hoarded vast reserves of precious metal—depicted in accounts like al-Tabari's—but this treasure became a target for the invading Rashidun armies at Ctesiphon. The episode traces how the empire's fiscal policies, including heavy…

Sassanid Persia's Fatal Mistake: The Battle of Dhi Qar

Jul 22, 2026 · 9:11

Before the Islamic conquests, the Sassanid Empire suffered a shocking defeat at the hands of Arab tribes at Dhi Qar in 609 CE. This episode explores how the Battle of Dhi Qar—fought near the Euphrates—shattered Persian military prestige and emboldened Arab resistance. We examine the role of the Banu Bakr and Taghlib tribes, the leadership of Hani' ibn Qabisah and the poet al-Muthaqqib, the capture of the Derafsh Kaviani by Arab forces, and the broader implications for the Arab-Persian frontier.…

The Sassanid Mistake That Brought the Plague of Shiruyeh

Jul 21, 2026 · 6:44

In 628 CE, as the Sassanid Empire spiraled into civil war, a devastating outbreak known as the Plague of Shiruyeh swept through Ctesiphon and the western provinces. This episode explores how the empire's internal strife created the perfect conditions for the pandemic—overcrowded refugee camps, disrupted trade, and a collapsed administration. We trace the plague's path from the Byzantine front to the heart of Persia, examine its role in the swift turnover of shahs (Kavadh II, Ardashir III…

The Sassanid Empire once controlled the Persian Gulf and Indian Ocean trade, but a series of strategic blunders left its navy crippled. In this episode, Lucas and Luna explore how the Sassanids lost naval supremacy to the Rashidun Caliphate, focusing on the Battle of the Chains and the destruction of the Siraf fleet. They discuss the role of the wuzurgan (nobility) in blocking naval investment, the rise of Arab maritime power, and the long-term consequences for Persian trade and defense. Key…

Sassanid Persia's Fatal Mistake: The Massacre of the Zoroastrian Clergy

In this episode, Lucas and Luna explore a little-known but devastating mistake that sealed the fate of the Sassanid Empire: the systematic massacre of Zoroastrian mobads and hērbads during the political chaos following Khosrow II's overthrow. After the coup of 628 CE, rival factions within the wuzurgan — the noble families — turned on the priestly class, whom they blamed for decades of religious persecution and failed prophecies. Lucas explains how the mobadhan, once the empire's spiritual…

Sassanid Persia's Fatal Mistake: The Great Purge of 628

Jul 20, 2026 · 7:06

In 628 CE, the Sassanid Empire convulsed in a civil war that saw three kings in a single year, culminating in the Great Purge ordered by Queen Boran. This episode explores how the empire's elite—the wuzurgan, mobadhan, and spahbed—turned on each other after the execution of Khosrow II, systematically eliminating military commanders, Zoroastrian priests, and noble families. We follow the short, bloody reigns of Kavadh II, Ardashir III, and Boran, focusing on the purge's devastating impact: the…

The Sassanid Fatal Mistake: Exiling the Christian Doctor Gabriel of Shiggar

Jul 19, 2026 · 8:52

The Sassanid Empire's collapse is often told through battles and betrayals, but this episode zooms in on a single, overlooked decision: the exile of Gabriel of Shiggar, a Nestorian Christian physician to Khosrow II. Gabriel's banishment after court intrigues fractured the fragile peace between the Zoroastrian elite and the empire's Christian subjects — just as the Byzantines and then the Rashidun Caliphate loomed. We trace how Gabriel's personal fall—tied to the rivalry between the wuzurgan and…

Sassanid Persia's Fatal Mistake: Denying the Kushan Refugees

Jul 19, 2026 · 6:37

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a little-known but devastating error of the late Sassanid Empire: the refusal to grant asylum to Kushan refugees fleeing the Hephthalite invasions in the 5th century CE. Under King Peroz I, the Sassanid court turned away thousands of displaced Kushan nobles, warriors, and artisans, who then settled in Sogdiana and eventually bolstered the Hephthalite ranks. Lucas explains how this decision backfired…

Episode 163 of The Biggest Mistakes That Destroyed Great Empires uncovers a rarely discussed but crucial factor in the Sassanid Empire's collapse: its systematic neglect of naval power. While earlier episodes have covered land battles, internal rebellions, and diplomatic failures, this episode dives into the Sassanids' curious lack of a blue-water navy in the Persian Gulf and Indian Ocean. Lucas and Luna explore how the empire's Sasanian rulers, despite controlling the entire northern shore of…

The Sassanid Empire's Fatal Mistake: Breaking the Sogdian Alliance

Jul 18, 2026 · 6:56

In this episode, Lucas and Luna explore one of the lesser-known but catastrophic missteps of the late Sassanid Empire: the alienation of the Sogdian merchants of Samarkand and Bukhara. As the Arab conquests pressed eastward after the fall of Ctesiphon, Yazdegerd III fled to Merv and sought refuge with the Sogdian lords. But decades of heavy taxation, broken trade agreements along the Silk Road, and a Zoroastrian religious crackdown on the Sogdian Buddhist and Manichaean communities had already…

By 636, the Sassanid Empire had collapsed, its armies shattered at al-Qadisiyyah and Nahavand. But the last king, Yazdegerd III, did not die in battle. He fled east, from court to court, a king without a throne, until he was murdered by a miller near Merv in 651. This episode follows Yazdegerd's desperate final years: his childhood as a fugitive in Estakhr, his rise to power at sixteen after a civil war, his fractured alliance with the dehqan nobility, and the betrayal that ended his life.

Sassanid Persia's Fatal Mistake: The Domino Effect of the Byzantine War

Jul 16, 2026 · 7:28

In this episode, Lucas and Luna explore how the Sassanid Empire's decades-long war with Byzantium—often seen as a final heroic stand—was actually a strategic blunder that drained resources, alienated allies, and left the empire vulnerable to the rising Rashidun Caliphate. They focus on the back-to-back campaigns of Khosrow II and his successors, the devastating sack of Jerusalem in 614 CE, the temporary recovery under Heraclius, and the crushing peace terms that impoverished Persia.

In this episode of The Biggest Mistakes That Destroyed Great Empires, Lucas and Luna explore a lesser-known but critical error of the Sassanid Empire: its neglect of the Persian Gulf. While historians often focus on the military defeats at al-Qadisiyyah and Nihavand, the Sassanids' failure to maintain a strong naval presence and secure maritime trade routes left the empire's southern flank exposed. Lucas explains how the empire's land-focused aristocracy, the wuzurgan, viewed the Gulf as a…

The Sassanid Empire's collapse wasn't just about battlefield defeats. In this episode, Lucas and Luna explore the overlooked role of the Arab tribes of the Syrian Desert — how the Lakhmid buffer state was dismantled, how nomadic groups like the Taghlib and Bakr shifted allegiances, and how the empire's hubris left its southwestern flank exposed. Drawing on al-Tabari, the Shahnameh, and recent scholarship, the conversation traces from Khosrow II's deposition of al-Nu'man III to the defection of…

In this episode, Lucas and Luna revisit the Sassanid Empire's collapse through the lens of the Battle of Jalula (637 AD), often called the 'lesser Qadisiyyah.' After the devastating defeat at al-Qadisiyyah, the Sassanid general Mihran rallied the remnants of the savaran and dehqan to make a stand at Jalula, northeast of Ctesiphon. Lucas explains how internal divisions among the wuzurgan and the failure of Yazdegerd III to provide coherent leadership doomed the Persian resistance. The episode…

How the Silk Road Pockets Betrayed the Sassanid Empire

The Sassanid Empire didn't just fall to Arab armies — it was starved of cash by its own merchant class. This episode explores how the great Persian trading families of Merv, Ctesiphon, and the Silk Road cities quietly shifted their loyalties when the Rashidun Caliphate offered lower taxes and safer trade routes. We examine the role of the wuzurgan (noble families) who controlled the caravans, the dehqan landlords who hoarded silver, and the pivotal 637 CE Battle of Jalula — where a Sassanid…
