The advocacy coalition framework (ACF) was developed to explain policy processes where contentious coalitions of actors seek to translate competing belief systems into public policy. Advocacy coalitions may include interest groups, members of the media, scientists and academics, and government officials that share beliefs about a public issue and coordinate their behavior. These advocacy coalitions engage in various strategies using resources to influence policy change or stasis. As part of this process, advocacy coalition members may learn within and/or across coalitions. This framework is one of the most prominent and widely applied approaches to explain public policy. While it has been applied hundreds of times, in over 50 different countries, the vast majority of ACF applications have sought to explain domestic policy processes. A reason for the paucity of applications to foreign policy is that some ACF assumptions may not seem congruent to foreign policy issues. For example, the ACF uses a policy subsystem as the unit of analysis that may include a territorial dimension. Yet, the purpose of the territorial dimension is to limit the scope of the study. Therefore, this dimension can be substituted for a government body that has the authority or potential authority to make and implement foreign policy. In addition, the ACF assumes a central role for technical and scientific information in the policy process. Such information makes learning across coalitions more conducive, but the ACF can and should also be applied to normative issues, such as those more common among foreign policy research. This article introduces the ACF; provides an overview of the framework, including assumptions, key concepts and theories, and transferability of the ACF to foreign policy analysis; and discusses four exemplary applications. In addition, it proposes future research that scholars should explore as part of the nexus of the ACF and foreign policy analysis. In the final analysis, the authors suggest the ACF can and should be applied to foreign policy analysis to better understand the development of advocacy coalitions and how they influence changes and stasis in foreign policy.
