General Assembly

The General Assembly is the main deliberative assembly of the United Nations. Composed of all United Nations member states, the assembly meets in regular yearly sessions under a president elected from among the member states. Over a two-week period at the start of each session, all members have the opportunity to address the assembly.  The first session was convened on 10 January 1946 in the Westminster Central Hall in London and included representatives of 51 nations.The Assembly may make recommendations on any matters within the scope of the UN, except matters of peace and security that are under Security Council consideration.

Security Council

The Security Council is charged with maintaining peace and security among countries. While other organs of the United Nations can only make 'recommendations' to member governments, the Security Council has the power to make binding decisions that member governments have agreed to carry out, under the terms of Charter Article 25. The decisions of the Council are known as United Nation Security Council resolutions.

The Secretariat

The Secretariat — an international staff working in duty stations around the world — carries out the diverse day-to-day work of the Organization. It services the other principal organs of the United Nations and administers the programmes and policies laid down by them. At its head is the Secretary-General, who is appointed by the General Assembly on the recommendation of the Security Council for a five-year, renewable term.

The International Court of Justice

The International Court of Justice (ICJ), located in The Hague, Netherlands, is the primary judicial organ of the United Nations. Established in 1945 by the United Nations Charter, the Court began work in 1946 as the successor to the Permanent Court of International Justice. The Statute of the International Court of Justice, similar to that of its predecessor, is the main constitutional document constituting and regulating the Court.

It is based in the Peace Palace in The Hague, Netherlands, sharing the building with the Hague Academy of International Law, a private centre for the study of international law. Several of the Court's current judges are either alumni or former faculty members of the Academy. Its purpose is to adjudicate disputes among states. The court has heard cases related to war crimes, illegal state interference and ethnic cleansing, among others, and continues to hear cases.

Economic and Social council

The Economic and Social Council (ECOSOC) assists the General Assembly in promoting international economic and social cooperation and development. ECOSOC has 54 members, all of which are elected by the General Assembly for a three-year term.

History of Uno.

The League of Nations failed to prevent World War II (1939–1945). Because of the widespread recognition that humankind could not afford a third world war, the United Nations was established to replace the flawed League of Nations in 1945 in order to maintain international peace and promote cooperation in solving international economic, social and humanitarian problems.  The term was first officially used on 1 January 1942, when 26 governments signed the Atlantic Charter, pledging to continue the war effort. On 25 April 1945, the UN Conference on International Organization began in San Francisco, attended by 50 governments and a number of non-governmental organizations involved in drafting the United Nations Charter. The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five permanent members of the Security Council—France, the Republic of China, the Soviet Union, the United Kingdom and the United States—and by a majority of the other 46 signatories. The first meetings of the General Assembly, with 51 nations represented, and the Security Council, took place in Westminster Central Hall in London in January 1946.

The organization was based at the Sperry Gyroscope Corporation's facility in Lake Success, New York, from 1946–1952, before moving to the United Nations Headquarters building in Manhattan upon its completion.

Since its creation, there has been controversy and criticism of the United Nations. In the United States, an early opponent of the UN was the John Birch Society, which began a "get US out of the UN" campaign in 1959, charging that the UN's aim was to establish a "One World Government." After the Second World War, the French Committee of National Liberation was late to be recognized by the US as the government of France, and so the country was initially excluded from the conferences that aimed at creating the new organization.
