"We the people of the United Nations, determined to save succeeding generations from the scourge of war, which twice in our lifetime has brought untold sorrow to mankind..."
As the Second World War came to a close, the immanence of the old world order met its demise, and from the ashes of a world desecrated by the zeal of war emerged the United Nations, an intergovernmental organization dedicated to the global peace and prosperity for all generations past, present and future.
On 25 April 1945, as Germany was officially liberated by the Allied powers and the curtains of the war in the European theatre came to a close, 50 governments convened in San Francisco for what would come to be known as the San Francisco Conference and started drafting the UN Charter, which was adopted on 25 June 1945 and took effect on 24 October 1945, when the UN began operations.
Pursuant to the Charter, the organization's objectives include maintaining international peace and security, safeguarding human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law. At its founding, the UN had 51 member states; with the addition of South Sudan in 2011, membership is now 193, representing almost all of the world's sovereign states.
The United Nations comprises six principal organs and many other subsidiary bodies, which are the United Nations General Assembly (UNGA), United Nations Security Council (UNSC), Economic and Social Council (ECOSOC), Trusteeship Council, International Court of Justice (ICJ), and the UN Secretariat, which is spearheaded by the Secretary General of the United Nations.
