Isn’t this a cool map? The places where states which controlled at least a million square kilometers before 1800 were founded, from Turchin, “A Theory for the Formation of Large Empires.” Look how many there are in North China and Southwest Asia, and how few in Southeast Asia or Europe! (Although part of that is the fact that we treat the long history of the Byzantine and Roman empires as one thing, but each Mongol or Chinese dynasty as different)
After a chat with T. Greer of The Scholar’s Stage, I read an interesting article by Peter Turchin called “A theory for formation of large empires” (2009). He is curious whether other world regions show the same pattern as China of empires beginning in the steppe or in the neighbouring farmland not the richest and safest agricultural districts. As he says, a lot of research focuses on the decline and disintegration of empires, not so much how a single king can come to rule millions or tens of millions of people in the first place: why do some empires last centuries when most fall to pieces within decades?
Turchin catalogued 64 states until the year 1800 CE with an area of at least a million square kilometers, and found that “over 90% of historical mega-empires were located next to or within the Old World arid zone extending from the Sahara desert to the Gobi desert” (which is a slightly different claim than the one about steppe frontiers, but never mind). When I read his list, one line popped out at me:
The table lists a Median empire with 2.8 million square kilometers in -585 (which is 586 BCE in Julian astronomical years with a year 0, but I think he means 585 BCE). That would have been as large as Iran, Afghanistan, and Pakistan combined. And the trouble is that such an empire probably did not exist, and if it did exist we don’t know its area.
