An international organization of countries set up in 1945, in succession to the League of Nations, to promote international peace, security, and cooperation.
The members of the United Nations, originally the countries that fought against the Axis Powers in the Second World War, now number 193 and include most sovereign states of the world. Administration is by a secretariat headed by a secretary general. The chief deliberative body is the General Assembly, in which each member state has one vote; recommendations are passed but are not binding on members and generally have had little effect on world politics. The Security Council bears the primary responsibility for the maintenance of peace and security and may call on members to take action, chiefly peacekeeping action, to enforce its decisions. The UN's headquarters are in New York City
