Public diplomacy is a political instrument with analytical boundaries and distinguishing characteristics, but is it an academic field? It is used by states, associations of states, and nonstate actors to understand cultures, attitudes, and behavior; build and manage relationships; and influence opinions and actions to advance interests and values. This article examines scholarship with relevance, usually unintended, to the study of public diplomacy and a body of analytical and policy-related literature derived from the practice of public diplomacy. Ideas wars globalism technologies political pressures, and professional norms shaped the conduct of public diplomacy and the literature of scholars and practitioners during the hot and cold wars of the twentieth century. In the twenty-first century, thick globalism, network structures, and new technologies are transforming scholarship, governance, and state-based public diplomacy. An achievable consensus on an analytical framework and a substantial scholarly and practical literature hold promise for an emerging academic field.
