This article details a simulation of formulating a new international human rights treaty designed for an introductory international studies course. Student understanding and interest in a range of international relations topics—including diplomacy, two-level games, international law, human rights, and group decision making—are reinforced by actively engaging the students in policy formulation and state-to-state negotiations. The article is structured around the four key components of active learning approaches—educational objectives, design parameters, procedures, and assessment and debriefing—in order to provide a full understanding of the goals, set-up, process, and advantages of the simulation. The simulation has been successfully run multiple times at both a large state university and a small liberal arts institution. Supportive student feedback and an interesting variety of outcomes indicate that this simulation is a positive addition to the course and reinforces the use of active learning approaches in the international studies classroom.
