The United Nations (UNO) is an international organization founded in 1945 with the goal of promoting international cooperation and maintaining peace and security among nations. It is made up of 193 member states, including nearly every recognized sovereign state in the world.
The UNO has six main organs: the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, the Secretariat, and the Trusteeship Council (currently inactive). Each organ has a specific role in carrying out the UN's mission.
The General Assembly is the main deliberative body of the UNO, where all member states have equal representation and can discuss and make recommendations on any issue within its scope. The Security Council is responsible for maintaining international peace and security by addressing threats to peace or acts of aggression. It has 15 members, five of which are permanent (China, France, Russia, UK, US) with veto power.
The Economic and Social Council works to promote economic development and social progress around the world. The International Court of Justice settles legal disputes between countries according to international law. The Secretariat is headed by the Secretary-General and carries out administrative tasks for all other organs.
