Because the world could not afford a Third War, the United Nations officially came into existence on October 24, 1945 after its charter was signed by the five permanent members of the Security Council–France, China, the (then) Soviet Union, the United States, the United Kingdom, and by a majority of the other 46 signatories.
There are currently 193 member states. The organization has six principal organs: the General Assembly, the Security Council, the Economic and Social Council, the Secretariat, the International Court of Justice, and the United Nations Trusteeship Council.
The UN’s World Development Information Day has also been held on 24 October since 1972.
