Abstract
This chapter traces the evolution of foreign policy analysis (FPA) as a subfield of international relations (IR) from its beginnings in the 1950s through its classical period until 1993; it then sketches the research agenda of contemporary FPA, which is represented by the other chapters in this volume. Three paradigmatic works, by Richard Snyder and colleagues, James Rosenau, and Harold and Margaret Sprout, laid the foundation of this subfield. In turn, these works created three main threads of research in FPA: focusing on the decision making of small/large groups, comparative foreign policy, and psychological/sociological explanations of foreign policy. These three primary areas of research have waxed and waned in importance to the subfield over the years. Current FPA scholarship explores linkages between these literatures, seeking both greater cross-level integration of explanation and new methodologies more appropriate to cross-level analysis.
