Formed by the United States, the United Kingdom, Russia, and China in the aftermath of World War II, the United Nations is the largest and most powerful intergovernmental organization in the world. The UN Charter was first signed on June 26, 1945, and entered into effect on October 24, 1945. A total of 51 member countries attended the UN General Assembly's first meeting, which took place in London, England on January 10, 1946. As of 2023, the UN includes 193 member states and two non-member observer states (full list below). Few sovereign territories exist that are not members of the United Nations.
The United Nations charter establishes four main goals for the organization:
The UN is made up of six main organs, five of which are active:
The remaining organ, the Trusteeship Council, technically still exists but has been inactive since 1994. The Trusteeship Council's role was to oversee and mentor non-sovereign "trustee" territories. The last trustee (Palau) obtained its sovereignty in 1994. Its purpose fulfilled, the council's operations were suspended. However, it has never been officially disbanded.
The UN also includes several specialized agencies which help the organization fulfill its duties and goals. These agencies include the World Health Organization, which performs vaccinations, and the World Food Programme, which helps overcome famine and prevent malnutrition around the world.
Non-member observer status was awarded to Palestine on 29 November 2012 and to Vatican City on 6 April 1964.
