What is United Nations?

Out of the Ashes:
After the end of the second world war, fifty-one countries assembled to host a series of meetings to deliberate on a peaceful way forward as mankind. The reasoning behind this meeting was to avoid the pain and suffering and loss of human life because of war.
So these countries agreed to create an international organisation that would be the forum for the peaceful resolution of differences and dialogue on a common way forward for humanity.
On 24 October 1945, the San Francisco Charter entered into force and the United Nations officially began its work.
"We the peoples of these United Nations determined to save succeeding generations from the scourge of war, which twice in our lifetimes have brought untold pain and sorrow to mankind ..."
