This research paper explores the pivotal roles of international organizations in conflict resolution, assessing their successes, challenges, and strategic impacts. It examines how entities like the United Nations (UN), African Union (AU), and European Union (EU) contribute to peacekeeping, diplomatic mediation, humanitarian aid, and legal support. The study highlights successful interventions, such as the UN’s role in Namibia and East Timor, demonstrating effective strategies in transitioning nations to peace. Conversely, it addresses the complexities encountered in ongoing conflicts like Syria and South Sudan, where geopolitical interests and operational difficulties impede resolution efforts. The analysis reveals that while international organizations can facilitate significant progress, their effectiveness is often constrained by political, logistical, and cultural challenges. Policy recommendations emphasize the need for enhanced political will, better resource allocation, and improved coordination among stakeholders. Future research directions include investigating the influence of geopolitical dynamics on conflict resolution and exploring innovative strategies for overcoming operational and cultural obstacles. This research aims to provide a comprehensive understanding of how international organizations can better address conflicts and contribute to global stability, offering valuable insights for both theory and practice in international relations.
