The UN was founded as a successor to the league of nations. It was established in 1945 immediately after. The organisation was set up through the signing of the United Nations charter by 51 states. It tried to achieve what the league could not between the two world wars. The UN's objective is to prevent international conflict and to facilitate cooperation among states.
