UN Day marks the anniversary of the entry into force in 1945 of the UN Charter. With the ratification of this founding document by the majority of its signatories, including the five permanent members of the Security Council, the United Nations officially came into being.
"This year again, we saw the United Nations come together on armed conflict, human rights, the environment and many other issues. We continue to show what collective action can do. We can do even more. In a world that is more connected, we must be more united. On United Nations Day, let us pledge to live up to our founding ideals and work together for peace, development and human rights. "
Secretary-General Ban Ki-moon
