Book excerpt: Empires have returned as features of the international scene. With the Cold War's global ideological contest gone, alternative structures such as the War on Terror or the Clash of Civilizations losing credibility, and even the unipolar position of the USA no longer self-evident, the operations of competing empires, history's best known form of order imposed over territories and peoples, acquires renewed credibility. Empire and International Order presents a critical examination of how useful the concept of empire is for understanding varieties of international order across time and place. Original contributions from an international team of upcoming and distinguished scholars analyse a wealth of theoretical approaches alongside contemporary themes enabling the reader to understand the desire to shift the ground of analysis away from the current literature of immediate issue of the US towards the disciplines of international relations, politics, and political/sociological theory.
