United Nations Poster, "Charter of the United Nations" 1945
President Franklin Roosevelt was committed to U.S. participation in an international peace organization. To avoid challenges faced by President Wilson, President Roosevelt was careful to build bipartisan support for Senate approval by including influential Republican Senator Arthur Vandenberg as a delegate to the United Nations Conference in San Francisco. The U.N. Charter was signed on June 26, 1945. A month later the U.S. Senate overwhelmingly approved it.
