McCarthianism is the term used to describe the communist resentment in America during 1950's. A senator by the name of Joesph McCarthy created a blacklist of "Communists" whom he tried prosecute. Many were communist party members, but some were just political enemies. In the aftermath of World War 2, McCarthy's accusations of Communists created a level of hysteria in the United States and he gained considerable power within congress. However, people eventually found out his motivations and he drifted back to obscurity. McCarthianism is the term used to describe the communist resentment in America during 1950's.
