Because urbanization in Tunisia started two millennia ago, tribal identity based on nomadism—which the medieval historian Ibn Khaldun said disrupted political stability—is correspondingly weak. Indeed, after the Roman general Scipio defeated Hannibal in 202 B.C . outside Tunis, he dug a demarcation ditch, or
fossa regia
, that marked the extent of civilized territory. The
fossa regia
remains relevant to the current Middle East crisis. Still visible in places, it runs from Tabarka on Tunisia’s northwestern coast southward, and turns directly eastward to Sfax, another Mediterranean port. The towns beyond that line have fewer Roman remains, and today tend to be poorer and less developed, with historically higher rates of unemployment. The town of Sidi Bouzid, where the Arab revolt started in December 2010, when a vendor of fruit and vegetables set himself on fire as an act of protest, lies just beyond Scipio’s line.
This is not fatalism. I am merely providing geographical and historical context to current events: the Arab revolt for democracy began in what in historical terms was the most advanced society in the Arab world—the one physically closest to Europe—yet it also began specifically in a part of that country which since antiquity had been ignored and suffered consequent underdevelopment.
Such knowledge can add depth to what has been transpiring elsewhere: whether it be in Egypt, another age-old cluster of civilization with a long history as a state just like Tunisia; or Yemen, the demographic core of the Arabian Peninsula, whose attempts at unity have been bedeviled by a sprawling and mountainous topography that has worked to weaken central government and consequently raise the importance of tribal structures and separatist groups; or Syria, whose truncated shape on the map harbors divisions within it based on ethnicity and sectarian identity. Geography testifies that Tunisia and Egypt are naturally cohesive; Libya, Yemen, and Syria less so. Itfollows, therefore, that Tunisia and Egypt required relatively moderate forms of autocracy to hold them together, while Libya and Syria required more extreme varieties. Meanwhile, geography has always made Yemen hard to govern at all. Yemen has been what the twentieth-century European scholars Ernest Gellner and Robert Montagne call a “segmentary” society, the upshot of a Middle Eastern landscape riven by mountains and desert. Hovering between centralization and anarchy, such a society in Montagne’s words is typified by a regime that “drains the life from a region,” even though “because of its own fragility,” it fails to establish lasting institutions. Here tribes are strong and the central government comparatively weak. 6 The struggle to construct liberal orders in such places cannot be divorced from such realities.
As political upheavals accumulate and the world becomes seemingly more unmanageable, with incessant questions as to how the United States and its allies should respond, geography offers a way to make at least some sense of it all. By engaging with old maps, and with geographers and geopolitical thinkers from earlier eras, I want to ground-truth the globe in the twenty-first century much as I did at these frontiers beginning in the late twentieth. For even if we can send satellites into the outer solar system—and even as financial markets and cyberspace know no boundaries—the Hindu Kush still constitutes a formidable barrier.

THE NAZI DISTORTION
As heirs to land power, Germans and Russians have over the centuries thought more in terms of geography than Americans and Britons, heirs to sea power. For Russians, mindful of the devastation wrought by the Golden Horde of the Mongols, geography means simply that without expansion there is the danger of being overrun. Enough territory is never enough. Russia’s need for an empire of Eastern European satellites during the Cold War, and its use of military power,
