Negotiation is less taught than might be expected in International Relations (IR) programs. Yet an upper-level university course is needed to address three audiences: future citizens, diplomats, and scholars. Since there is no single theory of negotiations, such a course needs to address the various conceptual approaches, grouped as Behavioral, Processual, Integrative, Structural, and Strategic. Conceptual presentations need to be supplemented with practitioners’ testimonies, simulations, and case studies, the latter using participants’ accounts as well as analyses. Games and a sample syllabus are presented.
