Following the end of World War II in 1945, 51 countries—including the United States—came together to form the United Nations, an international organization tasked with maintaining international peace and security, promoting social progress, and supporting universal human rights.
Seventy-two years later, the UN has grown to encompass 193 member states, and its work touches on a wide array of issues critical to humanity: from conflict prevention and peacekeeping, to sustainable development and environmental protection, to humanitarian assistance, refugee protection, nuclear non-proliferation, gender equality, and promoting good governance.
