Abstract: Peace and security has remained the global challenge in international relations and politics, through out the history of international relations. The study tries to capture the historical and theoretical development of efforts made by states and unions at providing and maintaining global peace and security in international relations. It analyses the contradictions and the implications of such efforts to global peace and security. Findings show that some states leaders had sincerely contributed their ultimate effort with utmost good faith towards peace and security in the world, while some have even manourverously instigated insecurity and tension within the international political atmosphere. The study concludes that states and nations struggle for power and some, for the elimination of others. This process, however, dislocates the stand, for global peace and security.
