New Study Questions a Major Assumption About the Fall of the Roman Empire

The period after the Roman Empire abandoned Britain has long been known as the “Dark Ages” for a reason. Scholars believed that after the Romans left, local industries collapsed and effectively all progress ceased for centuries. Britain, they theorized, was plunged into a cultural and economic abyss with their departure.

But for some time, a growing body of evidence has challenged this narrative. And in a new study published today in the journal Antiquity, researchers investigate the assumption that Britain’s metal economy ceased to function. Specifically, they interrogated the idea that when the Romans left Britain around the year 400, country’s lead and iron production—which the Romans may have brought with them to the isles—immediately and irreparably declined.

Reimagining northern England’s economy

The researchers studied metal pollutants in a sediment core extracted from Aldborough in North Yorkshire—a former Roman hub for metal production. They combined that analysis with other local textual and archeological evidence.

“Finding that fluctuations in pollution correspond with sociopolitical events, pandemics and recorded trends in British metal production c. AD 1100–1700, the authors extend the analysis to earlier periods that lack written records, providing a new post-Roman economic narrative for northern England,” the researchers argued in the paper.

Until now, the fate of Britain’s crucial metal industry after the Romans left was unknown, and there isn’t any written evidence testifying that lead production continued after the third century. The researchers’ approach, however, revealed that Britain’s metal production remained strong until about a century after the Romans left, experiencing a sudden drop some time around AD 550-600.

It remains a mystery what caused the crash, but other historical sources and DNA evidence suggest Europe was engulfed by the bubonic plague at that time, wreaking devastating to the entire region’s economy.

Britain’s rich history of making metals

Still, the research demonstrates that “not all industrial commodity production ended in the early 5th century,” Christopher Loveluck, lead author of the study and an archeologist at the University of Nottingham, said in a statement.

“At Aldborough, it is possible metal production expanded steadily using the ores and coal-fuel of the Roman period,” he added.

More broadly, Loveluck and his team’s work adds to the expanding body of evidence that suggests the so-called Dark Ages weren’t so dark after all.

Interestingly, the sediment core also reveals other post-Roman fluctuations in metal production that align with other pivotal events in British history—including Henry VIII‘s Dissolution of the Monasteries in the 16th century. During that time, metal production declined significantly because people were literally pulling metal off monasteries, abbeys, and other religious houses, Loveluck explains.
