Dumbarton Oaks Conference Opens to Plan United Nations
Summary
As World War II neared its end, Allied powers sought to create a new international organization to prevent future global conflicts. From August 21 to October 7, 1944, representatives from the United States, United Kingdom, Soviet Union, and China met at the Dumbarton Oaks estate in Washington, D.C. They drafted proposals for the structure of what would become the United Nations, including the Security Council and General Assembly frameworks. The conference built on earlier wartime agreements and addressed issues of collective security and postwar governance. China participated in a second phase after initial Soviet objections.
Why It Matters
The Dumbarton Oaks proposals formed the essential blueprint for the United Nations Charter adopted in 1945. The conference established core institutions that continue to shape international diplomacy, peacekeeping, and global cooperation today.
