Introduction

The United Nations (UN) came into existence after the catastrophic events of World War II, aiming to prevent future global-scale conflicts, and serving as a successor to the ineffective League of Nations. On April 25, 1945, representatives from 50 governments gathered in San Francisco to draft what eventually became the UN Charter. This charter was officially adopted on June 25, 1945, and took effect on October 24, 1945.

Functions of the United Nations

The organization, guided by its charter, has several key objectives, which include the maintenance of international peace and security, the protection of human rights, the delivery of humanitarian aid, the promotion of sustainable development, and the upholding of international law. Originally founded with 51 member states, the UN's membership expanded to 193 in 2011, encompassing the vast majority of the world's sovereign states.

Structure of the United Nations
The UN operates through five principal organs:

• General Assembly
• United Nations Security Council (UNSC)
• Economic and Social Council (ECOSOC)
• International Court of Justice
• UN Secretariat

The Trusteeship Council, once the sixth principal organ, suspended its operations on November 1, 1994, after granting independence to Palau, the last remaining UN trustee territory.
