The United Nations plays a central role in global governance by promoting international peace, security, and cooperation among countries. Established in 1945, the UN works to prevent conflicts, support peacekeeping operations, and encourage diplomatic solutions to global disputes. It also addresses global challenges such as climate change, human rights protection, poverty reduction, and humanitarian crises. Through its specialized agencies, programs, and forums like the General Assembly and Security Council, the UN provides a platform for dialogue and collective decision-making to maintain international stability.
