Conflict Management by International Organizations, 1945-1970 (ICPSR 5303)

Principal Investigator(s): Haas, Ernst; Butterworth, Robert Lyle; Nye, Joseph


This study contains data on 146 disputes in different geographical regions of the world that were managed by international or regional organizations in the period 1945-1970. Part of the project on Studies in International Integration of the Institute of International Studies at the University of California (Berkeley), this study was aimed at addressing how much difference international organizations have made in the management of international conflicts. Data are provided for conflicts brought before at least one of the following organizations whose primary concern was conflict management among members: United Nations, Organization of American States, Organization of African Unity, Arab League, and the Council of Europe. For each dispute, data are provided for the name of the conflict, issues at stake, power status of the parties involved, responses of the international organizations involved in managing the dispute, interstate nature of the dispute, duration of hostilities, civil and military fatalities, likelihood of the dispute abating, disappearing, or escalating if the disputing parties were left to themselves by the international organizations, and the likelihood that the United States and the Soviet Union would engage in a major war over the dispute, involving the use of nuclear weapons or massive conventional weapons on several fronts. A summary scale was developed by the investigators to measure the intensity levels of each dispute, and to score the successes of organizational management of the dispute.
