Synopsis UN has come a long way in facilitating global governance since its inception on June 26, 1945 as the international body. And in present world order UN has made itself indispensable. 50 years of its longevity and survival have attracted enormous global attention. An assessment of the evolved structure and function of this international organization would be very timely, so as to suggest possible reforms in near future, probably a reorganization of this institution for increasing its future credibility and role towards creating a new world order by the 21st century.
