A 19th century mansion in the Georgetown area of Washington, D.C. played a pivotal role in the world that followed World War II.
Between August and October, 1944, two international meetings known as the Dumbarton Oaks Conferences, were held there. The main objective was to discuss the possibility of creating an international organization to maintain world peace after the war.
The principles laid out ultimately were incorporated into the charter of the United Nations.
The meetings were attended by representatives of the United States, the Soviet Union, Great Britain and China. A main issue at stake was the use of the power of veto in the Security Council. Today the 16-acre Dumbarton Oaks estate is a research center for studies in Byzantine and pre-Columbian art and history.
