The document presents proceedings from the sixth in a series of annual national citizenship conferences. Held in Washington, D.C. in 1951, the conference served as a forum where educational, political, business, religious, labor, civic, and communications leaders could explore functions and duties of American citizenship. The theme of the conference was "Freedom in One World: Today and Tomorrow." Specific concerns of conference speakers included reviewing the responsibilities of the United States as leader of the free world and defining the role of the United States in stemming the tide of communism. Speakers stressed the need for American citizens to pursue active political cooperation, study of political matters, conscientious leadership, and respect for other people. Topics discussed include education of the foreign-born for citizenship, naturalization proceedings and problems, world freedom, citizenship in time of crisis, attitudes of youth toward citizenship, the role of the media in a changing world, and citizens' responsibility for freedom at home and abroad. Speakers included President Harry Truman, the attorney general of the United States (J. Howard McGrath), representatives of the National Education Association, United States senators from Oregon (Wayne Morse) and Tennessee (Estes Kefauver), members of the clergy, educators, media representatives, and young people representing the Boy Scouts of America, 4-H clubs, the National YMCA, the American Legion, and the United World Federalists.
