Abstract: This study examines the impact of revolutionary states upon international society. These states have always posed major problems for the achievement of world order: revolution is often accompanied by international as well as civil conflict, while revolutionary doctrines have proven to be highly disruptive of the existing structure of international politics. Conversely, the prevailing international order presents fundamental difficulties for some revolutionary states. The belief system on which its revolution was founded and which legitimized the assumption of state power by the revolutionary elite is certain to run counter to the prevailing political doctrines of many other states. David Armstrong asks whether revolutionary states are ‘socialized’ into adopting acceptable patterns of international behaviour, or whether it is the international society that is forced to change when these new states appear. He looks in detail at the French, American, and Russian revolutions and at several post-1945 revolutionary states. He also examines the relationship between revolutionary states and the principal ordering devices of an international society: international law, diplomacy, and the balance of power. His book is a significant contribution to the ‘English School’ literature, whose central concept is that of an international society. It shows how the interaction between revolutionary states and the established norms, rules, and institutions of international society works to produce change in both the revolutionary state and international society itself. As such it elucidates the dynamic aspects of international society.
