Theories of foreign policy: an historical overview

Although it is natural to consider the development of the comparative approach known as Foreign Policy Analysis (FPA) as the most obvious source of theories of foreign policy behaviour, it is important to remember that all perspectives on the subject of international relations contain statements about foreign policy. Historically this has been the case because virtually all approaches to the study of international relations took the state to be the central actor. Thus, approaches as diverse as those concentrating on political economy, international society and Marxism have all included a notion of what the state is and how its foreign policy results, regardless of the way in which policy might be defined. Theories of foreign policy are therefore intrinsic to theories of international relations, even for those who deny the centrality of the state as an actor in international society.
