Lecture on McCarthyism

McCarthyism is the term used to describe a period of intense suspicion in the United States during the early 1950s. It began when Senator Joseph McCarthy, a U.S. senator from Wisconsin, claimed that communists had infiltrated the Department of State. McCarthyism is the practice of making accusations of subversion or treason without proper regard for evidence. During this period, people from all walks of life became the subjects of aggressive “witch hunts” often based on inconclusive, questionable evidence.
