How does The Crucible stands as a parable for the Cold-War Era ?

 Miller wrote The Crucible not simply as a straight historical play detailing the Salem witch trials. Indeed, a good deal of the information in the play misrepresents the literal events of the trial: John Proctor was not a farmer, not a tavern owner, and during the time of the trials he was sixty years old and Abigail Williams only eleven. Rather, the play has as much significance as a product of the early Cold War era during which Miller wrote the play. Indeed, the play is a parable for the McCarthy era, in which similar 'witch hunts' occurred targeting citizens as communists rather than disciples of Satan.

Wisconsin Senator Joseph McCarthy was an undistinguished member of the Senate until February 1950, when he made the public charge that 205 Communists had infiltrated the State department. Upon subsequent testimony before the Senate Committee on Foreign Relations, McCarthy proved unable to produce the name of any "card-carrying" communists, but he gained increasing popular support for his campaign of accusations. Although he was later denounced, he promoted unfounded accusations and suspicions of communism in many quarters, and is best known for his investigation of communists in the United States Army.

The House Committee on Un-American Activities (generally known as HUAC) also investigated communism within Hollywood, calling a number of playwrights, directors and actors known for left-wing views to testify. Although some of these, including film director Elia Kazan, testified for the committee to avoid prison sentences, the Hollywood Ten, a group of entertainers, refused to testify and were convicted of contempt and sentenced to up to one year in prison. Over three hundred other entertainers were placed on a blacklist for possible communist views and were thus forbidden to work for major Hollywood studios (many of these were writers who worked under pseudonyms at the time, including Dalton Trumbo and Michael Wilson). Arthur Miller was one of these blacklisted. The blacklist prevented these men from receiving screen credit during this time, until actor Kirk Douglas pushed for Trumbo to receive screen credit for his adaptation of Spartacus for Stanley Kubrick in 1960.
