The document provides background information on Arthur Miller's play The Crucible, including the historical contexts of Puritanism, the Salem witch trials of 1692, and McCarthyism in the 1950s.

The document also summarizes some of the main characters in The Crucible like Abigail Williams, John Proctor, and Elizabeth Proctor.
