A Brief Introduction
The United Nations was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. It contains multiple subsidiary organizations to carry out its missions. In 1945, the UN had 51 members. It now has 193, of which more than two-thirds are developing countries. Because of their numbers, developing countries are often able to determine the agenda of the Assembly ，the character of its debates, and the nature of its decisions. For many developing countries, the UN is the source of much of their diplomatic influence and the principal outlet for their foreign relations initiatives.
Four of the official languages are the national languages of the permanent members of the Security Council (the United Kingdom and the United States share English as official language); Spanish and Arabic are the languages of the two largest blocs of official languages outside of the permanent members (Spanish being official in 20 countries, Arabic in 26). Five of the official languages were chosen when the UN was founded; Arabic was added later in 1973.
