New Data Reveal the Hidden Mechanisms of the Collapse of the Roman Empire
The reasons for the fall of the Western Roman Empire have remained a mystery for modern historians, just as for the Romans themselves. Yet, recent data from the Greenland ice core provide us with new data on collapse of the Empire, showing how fast and brutal it was – a true “Seneca Collapse.” Could our civilization go the same way? (above: the sack of Rome by the Visigoths of King Alaric in 410 AD).
The Ancient Romans never understood what hit them. Nor did later historians: there exist literally hundreds of theories on what caused the fall of the Roman Empire. In 1984 Demandt listed 210 of them, ranging from moral decline to the diffusion of Christianity. Today, some historians still say that the fall is a “mystery” and some attribute it to the improbable piling up of several independent factors which, somehow, happened to gang up together.
Why is it so difficult to understand something that was so massive as the fall of the Western Empire? There is more than one reason, but one is the lack of data. We have scant written material about the last centuries of the Empire and very little has arrived to us in terms of quantitative data. Things are changing, though. Modern archaeology is generating astonishing results telling us a lot about the mechanisms of the collapse of the ancient Empire. For instance, look at this graph: (from Sverdrup et al., 2013):
Recent data by McConnell et al on lead pollution provide a more detailed picture (See also Peter Turchin’s blog).
