Dumbarton Oaks: Blueprint for the United Nations Forged

Delegates from five major powers hammered out a framework for global cooperation at Dumbarton Oaks, then expanded that vision into the UN Charter during the San Francisco conference. Fifty governments ratified the document in October 1945, instantly creating an international body with headquarters on sovereign territory in New York City. Trygve Lie became the first Secretary-General, launching a permanent institution designed to prevent future world wars through collective security rather than isolated national defense.
