The founding document of the United Nations, the UN Charter, was signed on 26 June 1945, in San Francisco.
According to its Charter, the UN aims:
to save succeeding generations from the scourge of war,
to reaffirm faith in fundamental human rights,
to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained,
and to promote social progress and better standards of life in larger freedom.
