From the Princeton University Press description:
"Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria.
He takes readers from Rome’s pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted.
Harper describes how the Romans were resilient in the face of enormous environmental stress, until the besieged empire could no longer withstand the combined challenges of a “little ice age” and recurrent outbreaks of bubonic plague."
This is a highly readable, even exciting narrative which situates the Roman Empire within the climate cycle of the:
- Roman Climate Optimum (200 BC - 150 AD)
- Late Roman Transitional Period (150 - 450)
- Late Antique Little Ice Age (450 - 700).
This is by far the best, and most compelling account I have read of the dynamics underlying the fall of the Roman Empire (and also the rise of Islam, which brought the final coup de grace). Another case where climate science and paleogenetics are revolutionising history and archaeology.
One small criticism: Harper uses anachronistically the categories of capital and wage labour. But Rome was not capitalist, it was mercantilist, dominated by a mode of production based on ubiquitous slavery as Harper explains in great detail.
A few months ago I was freezing everywhere that there wasn't a heater, and last week I was roasting even overnight. Is this how the Roman Empire ended too?
ReplyDeleteAre there any lessons for current Empires?
Did I mention "The Year without a Summer"? Did I mention the major volcanic eruptions? Then there was the 60% mortality of the plagues. And the collapse of agricultural production and later the state apparatus itself. I think we have a way to go yet!
DeleteThe lessons for today, from the author, is that it is possible to get very complacent in the absence of major and sudden adverse climate change (chronic cold seems a particular problem, combined with too wet or too arid in the major production geographies) and lethal, highly infectious pandemics with no easy treatment. We need to stay lucky.
