The United Nations came into existence this date in 1945.
The United Nations (UN) is an intergovernmental organization formed to promote international cooperation. A replacement for the ineffective League of Nations, the organization was established after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193.
Headquarters of the UN is in Manhattan, New York City. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster and armed conflict.
