In lieu of an abstract, here is a brief excerpt of the content:Global Empires and The Roman ImperiumBrent D. ShawP. Fibiger Bang, C. A. Bayly, and W. Scheidel, eds. The Oxford World History of Empire. 2 vols. Oxford: Oxford University Press, 2021; xxviii + 552 pp.; xxxiv + 1,318 pp.The volumes under review are an impressive if unequal diptych. The first, the slimmer of the two, entitled "The Imperial Experience," comprises a series of analytical studies on the creation, management, and (...) ideologies of empires, and forms of resistance to them. The second, "The History of Empires," is a forbidding tome of forty-four specific studies of individual empires and imperial ventures, from Ur III and Middle Kingdom Egypt to the Mongols and the British, ending, naturally, with America's "global imperium." In the analytics, the usual suspects, including Michael Doyle, Frederick Cooper and Jane Burbank, are on display; and the conceptual approaches of Michael Mann and Ernest Gellner are favorite points d'appui. For premodern empires, the ideas of the Maghribi thinker Ibn Khaldūn provide a different focus, so it is heartening to see Bang and others applying them more consistently (e.g., 1:13, 40, 326–9; 2:162, 246–8, 253). Especially for premodern empires, these volumes can be seen as an extension of earlier handbooks devoted to the state, one devoted to the ancient Near Eastern and Mediterranean state and another on ancient empires.1 As an aspect of world history, the endeavor is the culmination of a decades-long project on the history of empires fronted by Peter Bang.2 He has usefully produced detailed historical introductions not only to both volumes, but also to the subsections in each of them. Perhaps not surprisingly, empire turns out to be a virile enterprise. As Ian Morris notes, "the story of empire... is so strongly gendered that it [End Page 505] seems reasonable to call rulers and commanders 'he' throughout" (1:162 n. 14). The muscular subject is mirrored by its principal actors and by its students. All the editors are men. Reflecting the same balance, out of the forty-five authors of individual studies in the large history of empires volume, there are five (lonely) female voices. In both volumes, women as subjects of empire are, for all intents and purposes, absent.3From the perspective of an historian who has actually worked on the history of an empire, it must be plainly stated that almost all of the theories, adequately reviewed by Bang (1:20–48), are worth about as much as the paper or pixilated screens on which they have been written. Obvious and serious exceptions to every one of the definitions and hypotheticals abound. In fact, a fair number of the exemplary histories in the second volume do not obey the strictures of most of the theories advanced in the first. So it is with a sense of relief that one turns from theory to the hard quantities offered by Walter Scheidel (1:chap. 2). To a considerable degree, his analysis depends on the well-known measurements made by Rein Taagepera. Rather alarmingly, Taagepera counted as an empire "any large sovereign political entity whose components are not sovereign," say, like the well-known empires of Algeria, Finland, or Canada.4 What an analysis of these global entities confirms is that size or orders of magnitude mattered, and that the first entities to count as empires emerged in the 7th to 5th centuries bce in southwestern Asia (1:53; 2:161, 245). The neo-Assyrian empire was the first super-large territorial state and its successor, the Achaemenid empire, was the first "hyper-power without rival" (1:172; 2:83, 111, 161). Subsequent premodern empires were able to reach higher levels of millions of square kilometers of territory and larger populations of dozens of millions of subjects nominally under their aegis. The magnitudes reached by a given generation of super-states set base-lines above which a successor might be able to reach greater sophistication of rule, numbers of subjects, and extent of territory. In some cases, being able to piggy-back on existing empires, they were able to skip early developmental stages and to advance quickly to imperial status, as a succession... (shrink)
