Clemson University students from a variety of majors participate in inter-collegiate competitions in the U.S. and abroad simulating the proceedings of the United Nations as well as international crises. Clemson MUN delegations have won successive domestic and international awards going back to 1989. Students can choose to either enroll in a special Political Science course (POSC 311) to provide one credit hour for participation in the program or join a student organization to participate. Aside from regular competitions and activities, members organize and run a Model UN competition for high schools (CUMUNC).
CIRA is a student organization housed in the Political Science department for promoting and carrying out international relations activities across campus. Activities include organizing roundtables and talks on current international affairs topics and coordinating with other internationally oriented student groups on campus.
