House Un-American Activities Committee (HUAC), a committee (1938-75) of the U.S. House of Representatives, created to investigate disloyalty and subversive organizations. Its first chairman, Martin Dies, set the pattern for its anti-Communist investigations. The committee's methods included pressure on witnesses to name former associates, vague and sweeping accusations against individuals, and the assumption of an individual's guilt because of association with a suspect organization. Witnesses who refused to answer were cited for contempt of Congress. A highly publicized 1947 investigation of the entertainment industry led to prison sentences for contempt for a group of recalcitrant witnesses who became known as the Hollywood Ten. In 1948, Whittaker Chambers made sensational accusations of Soviet espionage against former State Dept. official Alger Hiss; those hearings kept the committee in the headlines and provided the first national exposure for committee member Richard Nixon. Critics of the committee contended that it disregarded the civil liberties of its witnesses and that it consistently failed to fulfill its primary purpose of recommending new legislation. After 1950, Sen. Joseph McCarthy borrowed many of the committee's tactics for his own Senate investigations. The committee (renamed the House Internal Security Committee in 1969) was abolished in 1975.

International organization founded (1945) at the end of World War II to maintain international peace and security, develop friendly relations among nations on equal terms, and encourage international cooperation in solving intractable human problems. A number of its agencies have been awarded the Nobel Prize for Peace, and the UN was the corecipient, with Kofi Annan, of the prize in 2001. The term originally referred to the countries that opposed the Axis powers. An international organization was discussed at the Yalta Conference in February 1945, and the UN charter was drawn up two months later at the UN Conference on International Organization. The UN has six principal organs: the Economic and Social Council, the United Nations General Assembly, the International Court of Justice, the Secretariat, the United Nations Security Council, and the United Nations Trusteeship Council. It also has 14 specialized agencies—some inherited from its predecessor, the League of Nations (e.g., the International Labour Organization)—and a number of special offices (e.g., the Office of the United Nations High Commissioner for Refugees), programs, and funds (e.g., UNICEF). The UN is involved in economic, cultural, and humanitarian activities and the coordination or regulation of international postal services, civil aviation, meteorological research, telecommunications, international shipping, and intellectual property. Its peacekeeping troops have been deployed in several areas of the world, sometimes for lengthy periods (e.g., they have been in Cyprus since 1964). The UN's world headquarters are in New York City; its European headquarters are in Geneva. In 2005 the UN had 191 member countries. The principal administrative officer of the UN is the secretary-general, who is elected to a five-year renewable term by the General Assembly on the recommendation of the Security Council. The secretaries-general of the UN have been Trygve Lie (1946–53), Dag Hammarskjöld (1953–61), U Thant (1961–71), Kurt Waldheim (1972–81), Javier Pérez de Cuéllar (1982–91), Boutros Boutros-Ghali (1992–96), and Kofi Annan (from 1997).
