The course is designed to explore the origins, nature and evolution of regional co-operation and/or integration among states in the international system. It also examines the theoretical assumptions of regionalism and the contemporary trends and issues of regional politics. Conceptually, the various approaches to integration are analysed. These are federalism, functionalism, neo-functionalism, supra-nationalism, communications and transaction. In addition, regional organisations like the EU, OAU, NATO, NAM and the Commonwealth are focused upon. Sub-regional organisations like ECOWAS, ASEAN, NAFTA, SADC and the Arab League are also explored. The structure, membership functions, problems or limitations and successes of these bodies are emphasised.
