"Analytically rigorous, historically rich, and theoretically innovative ... [An] outstanding work of scholarship."Australian Journal of Political Science"An essential read for all those who are interested in the meaning of empire today, be it within academia or the wider public."Nations and Nationalism"In this excellent book, Alejandro Colás draws together a wide range of theoretical perspectives and combines them with rich historical detail to illustrate his argument. That he does so in a concise, readable and yet rigorous way is something to be applauded. In short, Empire is a highly impressive achievement."Ray Kiely, University of London"This is an impressive and erudite contribution to the international relations literature on empire. Its distinctive approach, which focuses upon the spatial, economic, and cultural attributes of empire, works very effectively."Anthony McGrew, University of Southampton
