The main purpose of the United Nations (UN) is to promote peace, security, and cooperation among its member states. Founded in 1945 after World War II, the UN aims to prevent future conflicts, foster international dialogue, and address global challenges such as poverty, human rights, and environmental sustainability. The organization facilitates diplomatic negotiations, provides humanitarian aid, and coordinates efforts to tackle issues like climate change and health crises. Through various agencies and programs, the UN plays a pivotal role in promoting development and upholding international law, striving for a safer and more equitable world.
