[email protected] The emergence of a regional, aristocratic polity was a shift from the Carolingian past, and historians have proffered Funding information Leverhulme Trust, Grant/Award Number: several explanations for it. This article examines several ECF-2017-693 models for the development of principalities: as the expres- sions, however compromised, of ethnic separatism; as the evolved forms of ninth-century administrative structures; and as aristocratic power constellations no different from any other. It traces the history of Aquitaine from the first duke, William the Pious, in the early tenth century, to the Poitevin dukes of the mid-eleventh century. The post- Carolingian duchy of Aquitaine, it is argued, is best under- stood not as an ethnic or an institutional formative, but as the distinctive expression of a changing regional political culture. 1 | INTRODUCTION The emergence of discrete, regional, non-royal political units (known, by an historian's term of art, as ‘principalities’) in what is now France over the course of the late ninth through early eleventh centuries is an historical puzzle. Prob- ably the most profound is how we are to characterise these polities: a break, an evolution or just the nobility's power essentially unchanged but dressed up in flashy new titles? Historians have up to the present struggled to characterise the emergence, out of a Carolingian world where aristocratic polities were conspicuous by their absence of regional political units such as Normandy, Burgundy and, of course, Aquitaine.
