The document discusses the Salem Witch Trials of 1692 and Arthur Miller's play The Crucible. It describes how religious persecution in their native England led Puritans to settle in America but they later persecuted others through hysteria over witches. Accusations of witchcraft stemmed from spectral evidence and led to executions. The Crucible was written by Miller as an allegory for the anti-Communist hysteria and witch hunt led by Senator McCarthy in the 1950s.
