What we call empires have varied greatly from place to place and from time to time. Nevertheless, they have shared many of the same opportunities, challenges, and constraints in their expansion, administration, and dissolution. We participate in the broader scholarly trend of bridging historiography on different empires, including the Mughal, Ottoman, Japanese, Roman, Byzantine, and a variety of African states; European colonial empires with significant overseas possessions, notably those of Iberia, Britain, and France; and also the indigenous groups they encountered in Africa, Asia, and throughout the Americas. Many of us examine the lived experience of empire—at the level of the nation-state, the region, and the individual—and explore things like the creation of, and institutionalization implementation of, imperial ideologies; regional adaptations in material culture and trade networks in spaces of cultural contact; resistance, revolutions and rebellions; and the processes of acculturation and creolization. Others of us give attention to the aftermath, or “echo” of empire in these different registers. We investigate the broader impacts of imperialism in its various guises, with an eye to issues such as the return of former colonial inhabitants (“peripheries”) to European metropoles (“centers”), decolonization, and the ways post-colonial peoples around the globe have interpreted and articulated their own colonial pasts. We welcome inquiries from prospective graduate students interested in the history of empire in its various iterations.
