The Dumbarton Oaks Conference was a series of meetings held in 1944 in Washington, D.C., aimed at discussing the establishment of a new international organization to promote peace and security after World War II. Delegates from the United States, United Kingdom, Soviet Union, and China participated in these discussions, laying the groundwork for what would eventually become the United Nations. During the conference, key issues such as the structure of the proposed organization, the voting system, and the roles of member states were debated. The outcomes of the Dumbarton Oaks Conference significantly influenced the formation of the UN and its charter, which was adopted later in 1945.
