This article examines the intraregional conflict management activities of the Organization of African Unity (OAU). Three traditional regionalist claims are tested and suggestions concerning the future role of such organizations are provided. The findings indicate that in a number of cases the OAU was not an effective agent for conflict management; its limitations were clearest in internal disputes and those international conflicts involving allegations of subversion. Evidence from this study does not convincingly support the proposition that similarities of interests, problems, and loyalties found at the regional level make it more likely that attempts at settlement will be forthcoming and successful. Other findings indicate that the organization was able to isolate intra-regional conflicts from entanglement in more complex global disputes; this ability was, however, highly dependent on the desire of the great powers to remain uninvolved. The OAU was able to relieve the UN of the potential burden of numerous local conflicts, but this too sometimes proved dependent on policy decisions made by the United States or the Soviet Union. It is suggested that regional organizations may assist the superpowers in avoiding unwanted involvement in local disputes, but that unless the conflict management capacity of such organizations is increased, the result may be that many conflicts will remain unsettled.
