As an organisation committed to promoting peace and international order, the United Nations (UN), at 80 years, has lasted longer than any other previous attempts at global governance.These include the post-Napoleonic Concert of Europe and the post-Great War League of Nations.

In its initial stages, the UN owed its existence to two American power men from New York - Franklin Delano Roosevelt and Nelson A.

Rockefeller.

Over time, the UN went through systemic and manufactured hardships and trials.
