United Nations

"The United Nations is bound together for all countries of the world to keep the planet in peace, but now, and unfortunately, they have failed to keep the whole world in control."

--Su Ji-Hoon, The Great Failure

The United Nations (UN) is an intergovernmental organization tasked to promote international cooperation and to create and maintain international order. A replacement for the ineffective League of Nations, the organization was established on October 24, 1945 after World War II with the aim of preventing another such conflict. At its founding, the UN had 51 member states; there are 193 as of 2018. The headquarters of the UN is in Manhattan, New York City, and is subject to extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world.

The UN Charter was drafted at a conference between April-June 1945 in San Francisco, and was signed on 26 June 1945 at the conclusion of the conference; this charter took effect 24 October 1945, and the UN began operation. The UN's mission to preserve world peace was complicated in its early decades by the Cold War between the US and Soviet Union and their respective allies. The organization participated in major actions in Korea and the Congo, as well as approving the creation of the state of Israel in 1947. The organization's membership grew significantly following widespread decolonization in the 1960s, and by the 1970s its budget for economic and social development programmes far outstripped its spending on peacekeeping. After the end of the Cold War, the UN took on major military and peacekeeping missions across the world with varying degrees of success.

The UN has six principal organs: the General Assembly (the main deliberative assembly); the Security Council (for deciding certain resolutions for peace and security); the Economic and Social Council (ECOSOC; for promoting international economic and social co-operation and development); the Secretariat (for providing studies, information, and facilities needed by the UN); the International Court of Justice (the primary judicial organ); and the UN Trusteeship Council (inactive since 1994). UN System agencies include the World Bank Group, the World Health Organization, the World Food Programme, UNESCO, and UNICEF. The UN's most prominent officer is the Secretary-General, an office held by Portuguese António Guterres since 2017. Non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the UN's work.

The organization won the Nobel Peace Prize in 2001, and a number of its officers and agencies have also been awarded the prize. Other evaluations of the UN's effectiveness have been mixed. Some commentators believe the organization to be an important force for peace and human development, while others have called the organization ineffective, corrupt, or biased.

Background
In the century prior to the UN's creation, several international treaty organizations and conferences had been formed to regulate conflicts between nations, such as the International Committee of the Red Cross and the Hague Conventions of 1899 and 1907. Following the catastrophic loss of life in the First World War, the Paris Peace Conference established the League of Nations to maintain harmony between countries. This organization resolved some territorial disputes and created international structures for areas such as postal mail, aviation, and opium control, some of which would later be absorbed into the UN. However, the League lacked representation for colonial peoples (then half the world's population) and significant participation from several major powers, including the US, USSR, Germany, and Japan; it failed to act against the Japanese invasion of Manchuria in 1931, the Second Italo-Ethiopian War in 1935, the Japanese invasion of China in 1937, and German expansions under Adolf Hitler that culminated in the Second World War.
