Formed in 1945, the United Nations remains the largest and most important international organization in the world, providing a vital forum for dialogue among virtually all nations. Developed to promote peace and avoid conflict, UN programs help pool global resources to confront challenges such as poverty, health, climate change, and migration, while also providing peacekeepers to conflict zones. Both developed and developing countries have also pushed for reform of the organization to account for the dramatic changes in economic and political power around the world.
