The United Nations Day is observed every year on 24th October to mark anniversary of entry into force of UN Charter in 1945. With ratification of this founding document by majority of its members, including five permanent members of UN Security Council, United Nations officially came into existence.
Since then, 24th October is celebrated as UN Day. On this day all member states of UN contribute finances to its operation to help further its goals.
UN is successor of ineffective League of Nations and was established in 1945 after World War II in order to prevent another such conflict. Now, it has become world’s only truly universal global organization and is foremost forum to address issues that transcend national boundaries and cannot be resolved by any one country acting alone.
Its prime role is to maintain world peace, human rights, promote social and economic development and provide aid around the world in cases of famine, natural disaster and armed conflict.
The main organs of UN are: General Assembly (UNGA), Security Council (UNSC), Economic and Social Council (UNESOC), International Court of Justice (ICJ), UN Secretariat, Trusteeship Council.
