Introduction

In the episode titled "Fall of Roman London," hosted by Tristan Hughes, listeners are taken on an in-depth exploration of Londinium's decline during the later stages of Roman Britain. The episode features Dr. Dominic Perring, emeritus professor from University College London and a leading expert on Roman London, who provides comprehensive insights into the archaeological and historical factors contributing to the city's transformation.

Early Roman London: Foundation and Growth

Foundation and Early Prosperity
Dr. Dominic Perring begins by outlining London's origins as a Roman city, established around AD 43 under Emperor Claudius. "London was originally a Roman city. For more than 300 years, it was the administrative and economic center of Roman Britain, of Britannia," he states (01:00). At its peak, Londinium housed an estimated population of 30,000 and featured significant Roman architecture, remnants of which lie buried beneath modern London.

Resilience Post-Rebellion
The city demonstrated remarkable resilience following Boudicca's rebellion in the mid-1st century AD. "The resilience is from the top down... They enhance and rebuild the waterfront," Perring explains (06:13). This rebuilding effort reaffirmed London's status as a pivotal administrative hub, quickly restoring its economic and structural integrity.

Mid-Third Century Crisis: Signs of Decline

Economic and Structural Shifts
By the mid-third century AD, Londinium began experiencing significant changes. Perring notes, "There is a third century contraction, less well defined," which he attributes to the broader "economic changes of what's called the crisis" (12:55). This period, often referred to as the Third Century Crisis, saw economic instability and external threats impacting Roman Britain.

Decline of the Waterfront
A critical shift occurred with the modification of the waterfront. "They get rid of most of it... The port of London is clearly not functioning in quite the way it used to," Perring details (14:05). This deliberate alteration signified a move away from Londinium's role as a major trade hub, potentially due to reduced need for large-scale shipments and increased concerns over maritime security, including rising piracy.

Impact of the Gallic Empire
The fragmentation of the Roman Empire, particularly the establishment of the Gallic Empire, disrupted central control and trade routes. "The Gallic Empire is very material... the northwest provinces have been separated from their own empire," Perring explains (15:18). This separation hindered Londinium's connectivity with the broader Mediterranean trade networks, exacerbating its decline.

Late Third Century Revival: Attempts at Stabilization

Reconstruction Efforts
Despite earlier declines, Londinium saw a period of revival in the late third century AD. "There's a rebuilding of the waterfront... associated with timber supplies," Perring mentions (18:12). This reconstruction was part of efforts to stabilize the region and reassert Roman control under Emperor Aurelian, who successfully reintegrated the Gallic Empire back into Rome.

Continued Economic Activity
During this revival, evidence shows the import of regional goods, such as Alice Holt pottery from Hampshire, indicating a shift towards a more localized economy. "There's a rebalancing of the regional economy associated with London's revival in the late third century," he notes (20:21).

Emergence of Prominent Figures
The period also saw the rise of local leaders like Allectus, who attempted to establish a breakaway empire in Britain. "They are using the same craftsmen because the building techniques are identical," Perring explains (23:10). However, these attempts were short-lived, as Central Roman authority swiftly reasserted control.

Fourth Century Changes: Administrative and Religious Shifts

Administrative Realignment Under Constantine
With the rise of Constantine in the early fourth century, Roman administrative structures underwent significant changes. Constantine's consolidation efforts reduced the need for regional commands, diminishing Londinium's importance. "Once we get into the 4th century, following Constantine's elevation, we get less in the way of archaeological activity going on in London" (27:18).

Rise of Christianity
The fourth century also marked the increasing presence of Christianity in Londinium. "While archaeology doesn't well attest to Christianity in Britain, we have church figures beginning to appear," Perring states (31:35). Evidence includes early Christian symbols found in burial sites and potential basilical structures, indicating the religion's growing influence despite limited architectural remains.

Cemeteries and Shifts in Burial Practices
There was a notable shift from cremation to inhumation in burial practices during this period, reflecting broader religious and cultural changes. "Most of our cemetery evidence comes from the later period... the favored method of dealing with rich people's burial was to cremate them in the early Roman period, and in the late Roman period, it is to bury them" (39:42).

Late Fourth Century: Structural Transformations and Final Decline

Architectural Enhancements and Defenses
In the late fourth century, Londinium underwent further architectural changes, including the addition of bastions to the city walls. "They add them to select locations on the city wall... to better defend and mark the site as prestigious," explains Perring (43:21). These enhancements were likely responses to ongoing security concerns and reflected continued investment by Roman authorities.

Economic Struggles and Coinage Shortages
The late fourth century also experienced economic hardships, characterized by a shortage of coinage and the rise of local forgeries. "Local manufacture, people start forging... to keep things going," Perring notes (56:24). This shortage hindered monetary transactions, further straining Londinium's economy.

Impact of Usurpers and Military Withdrawal
The emergence of usurpers like Magnus Maximus, who originated from Britain, played a pivotal role in Londinium's final decline. "Constantine III is another of these leaders who ends up withdrawing troops from Britain to fight campaigns in Gaul," Perring states (60:03). The withdrawal of military forces undermined Rome's authority and left Londinium vulnerable.

Final Signs of Decline
Archaeological evidence from the 380s indicates significant disruptions, such as road deterioration and abandoned buildings. "Houses next to the street on the north side look to be abandoned... and the street itself being damaged," Perring describes (53:58). These signs foreshadowed the city's eventual abandonment as Roman control waned.

Conclusion: The Disappearance of Roman London

Dr. Dominic Perring concludes that Londinium's disappearance was not an abrupt event but a gradual decline linked to Rome's inability to maintain authority in Britain. "London ceased to exist because Rome failed to maintain authority in Britain and the city had no other evident reason for being," he summarizes (60:41). The economic benefits of Roman investment were unevenly distributed, favoring a privileged few, and the harsh administration alienated the broader population, leading to the city's eventual abandonment.

Final Remarks
The episode wraps up with Perring highlighting the distinction between the urban decline and the changing countryside, suggesting that while Londinium faded, the surrounding regions continued to evolve independently. "The countryside is changing at a different pace to the city," he reflects (61:12).
