The organization established in 1945 to promote international cooperation and prevent conflict is the United Nations (UN). Formed in the aftermath of World War II, the UN aimed to foster peace and security among nations, provide a platform for dialogue, and promote human rights and social progress. Its founding members sought to prevent the recurrence of devastating wars by enabling collective security, facilitating humanitarian aid, and addressing global issues such as poverty and health. Over the decades, the UN has played a vital role in peacekeeping, conflict resolution, and fostering international development partnerships.
