For an empire that collapsed more than 1,500 years ago, ancient Rome maintains a powerful presence. About 1 billion people speak languages derived from Latin; Roman law shapes modern norms; and Roman architecture has been widely imitated. Christianity, which the empire embraced in its sunset years, remains the world’s largest religion. Yet all these enduring influences pale against Rome’s most important legacy: its fall. Had its empire not unravelled, or had it been replaced by a similarly overpowering successor, the world wouldn’t have become modern.

This isn’t the way that we ordinarily think about an event that has been lamented pretty much ever since it happened. In the late 18th century, in his monumental work The History of the Decline and Fall of the Roman Empire (1776-1788), the British historian Edward Gibbon called it ‘the greatest, perhaps, and most awful scene in the history of mankind’. Tankloads of ink have been expended on explaining it. Back in 1984, the German historian Alexander Demandt patiently compiled no fewer than 210 different reasons for Rome’s demise that had been put forward over time. And the flood of books and papers shows no sign of abating: most recently, disease and climate change have been pressed into service. Wouldn’t only a calamity of the first order warrant this kind of attention?

It’s true that Rome’s collapse reverberated widely, at least in the western – mostly European – half of its empire. (A shrinking portion of the eastern half, later known as Byzantium, survived for another millennium.) Although some regions were harder hit than others, none escaped unscathed. Monumental structures fell into disrepair; previously thriving cities emptied out; Rome itself turned into a shadow of its former grand self, with shepherds tending their flocks among the ruins. Trade and coin use thinned out, and the art of writing retreated. Population numbers plummeted.

But a few benefits were already being felt at the time. Roman power had fostered immense inequality: its collapse brought down the plutocratic ruling class, releasing the labouring masses from oppressive exploitation. The new Germanic rulers operated with lower overheads and proved less adept at collecting rents and taxes. Forensic archaeology reveals that people grew to be taller, likely thanks to reduced inequality, a better diet and lower disease loads. Yet these changes didn’t last.

The real payoff of Rome’s demise took much longer to emerge. [Continue reading…]
