The Two Military Revolutions Responsible for Empire
Peter Turchin:
“The main driver of “imperiogenesis” (processes underlying the rise of empires) is interstate competition. The intensity of this competition, in turn, is dialed up by advances in military technologies. Each military revolution, thus, generates a set of mega-empires. Today we live in the historical shadow of two most consequential military revolutions.
The iron-cavalry revolution dates to about 1000 BCE. Although horse riding and iron smelting were invented independently , by 500 BCE they were spreading together . And the detailed story of this military revolution and its profound effects on world history are in my book Ultrasociety.
To cut the long story short, the iron-cavalry revolution transformed the Great Eurasian Steppe into an engine of imperiogenesis. This continental heartland was the home of nomadic pastoralists, whose main military force consisted of horse archers. Most of the premodern mega-empires were located on the “shores” of this “sea of grass” (see the second infographic below).
One such imperial cluster, north China, abutted the eastern steppe region (Greater Mongolia). Another cluster, Iran, faced the central steppe (Turkestan). The third, Russia, developed under the influence of the western steppe (the Pontic-Caspian region). Northeastern Europe was a bit of late-comer, because its forest regions acquired agriculture quite late (only by the end of the First Millennium CE). But what unifies all three imperial regions, China, Iran, and Russia, was that they all developed in close interaction with the Inner Asians.
The other consequential revolution was, of course, the one that originated in Western Europe around 1400 CE. It’s two components were gunpowder weapons and ocean-going ships. So I refer to it as the “Gunship Revolution.” The parallels between the two revolutions are quite striking. Inner Asians rode horses and shot arrows, while Europeans rode ships and shot cannon balls. The world ocean played the same role as the “sea of grass.” Historians noted these similarities. For example, the historian of Southeast Asia, Victor Lieberman, referred to Europeans as “White Inner Asians.”
Readers, who are familiar with geopolitical theories of Mackinder, Mahan, Spykman, and others (if not, check out this Wikipedia article), will immediately recognize the similarities between what I am talking about here and various geographical concepts central to these theories (the Heartland, the Rimland, the Islands…). What my historical analysis shows is that the conflict between the American Empire and China+Russia+Iran was shaped by the two great military revolutions, thus clarifying and refining the traditional geopolitical theories.
Thus, the Great Steppe (which is treated as a pivotal region by several geopolitical theories) today is of little significance, except for its historical effect. By 1900 it was completely taken over by Russia and China. Today it’s home to a bunch of weak and geopolitically insignificant states, such as Mongolia and the “Stans.” The successors of old mega-empires, which arose on the Steppe frontiers, is where Eurasian power now resides.
The second pole of power is “Oceania,” which originated on the western shores of Eurasia during the sixteenth century (Portugal, Spain, the Netherlands, and the British Isles), then spread across the Atlantic, and now is a global empire, ruled from Washington and Brussels as a secondary capital (although there are cracks between these two seats of power due to Donald Trump’s policies). A good way to visualize this geopolitical entity is a map of American military bases. Oceania’s geopolitical logic—encirclement of Eurasian empires—is obvious.”
