The purpose of this study is to explore the activities of transnational organizations which were involved in the Nigerian civil war, in order to evaluate the hypotheses of this study - that the transnational organizations studied here contributed to the outbreak of the civil war; that they attempted to influence the behavior of the conflicting parties; that they helped to prolong the war; and that they served as instruments of conflict resolution in the civil war. The final chapter summarizes the conclusions arrived at in various chapters of the study. The evidence yielded varying degree of support to the hypotheses, These transnational actors are seen to have, through their different interactions with both sides affected the course of the war and have produced mixed impacts. They produced some evidence for the explanation of behavioral patterns likely to be displayed by transnational actors in similar situations. Also, these interactions are seen as giving some validity to the perceived need to expand the analytic framework of actors in international politics.
