This essay begins with a summary overview of emergent intellectual trends that are redefining the study of empire today. It then charts a history of modern Irish scholarship on empire, discussing the achievements and limitations of Atlantic History, Commonwealth History, and postcolonial studies. 1 The piece closes with a discussion of how Empire Studies in Ireland might be reoriented in the future so as to deal not only with Irish responses to the now-vanished British Empire but also to the wider European imperial system and to the American neo-imperialism that emerged in its wake. Empire Studies and the Crises of American Imperialism Not so long ago the historiography of empire was a sedate enterprise with the air of a somewhat inconsequential intellectual tidy-up operation in which mostly Western historians deliberated the character of European empires gone the way of Nineveh and Tyre. For a time, the very word "imperialism" seemed even to be becoming obsolete due to the collapse of Marxist theory's intellectual stock 11 . These fields obviously do not cover the entire gamut of Irish scholarship on empire. Several other fields might be discussed, including the economic history of empire, scholarship on Northern Ireland, studies of empire in eighteenth-and nineteenth-century contexts, and so on. However, they do represent major concentrations of work and thus represent significant contributions to the development of Empire Studies in Ireland. Amongst Empires: A Short History of Ireland and Empire Studies in International Context after and to its displacement by newer lexicons like "globalization." Now, as Giovanni Arrighi has remarked, the "E" and "I" words are very much back in fashion and, what is more, the study of empire and imperialism has lost much its aura of retrospection, its romance of requiem. 2 And as this has occurred, the center of gravity of Empire Studies has also moved westward from Britain and France to the United States. When contemporary intellectuals debate the economics of imperial expansion, the nature of interimperial competition, or the dangers of over-stretch, they do so less as archivists of a disappearing age and more in the manner of auguries hoping to discern the outline of a new world in the entrails of the old. The current reinvigoration of Empire Studies owes much to scholars who have worked to rehabilitate the idea of empire, not least by arguing that the United States should assume the imperial functions relinquished by Britain and France after World War II. Refurbishing arguments about imperialism as midwife to modernization and enlightenment, this scholarship is also advanced on the "realist" premise that in an inherently war-prone international state system it will always be necessary for some master-state to regulate the world. Hence, unless a twenty-first century pax Americana can replicate its nineteenth-century British predecessor, the world is doomed in the century ahead either to long-term chaos or to the prospect that some non-Western power will assume the Augu...
