McCarthyism has entered American speech as a general term for the phenomenon
of mass pressure, harassment, or blacklisting used to pressure people to follow popular
political beliefs.
Puritanism- Puritans was the name given in the 16th century to the more extreme
Protestants within the Church of England who thought the English Reformation
had not gone far enough in reforming the doctrines and structure of the church;
they wanted to purify their national church by eliminating every shred of Catholic influence.
Crucible- The Crucible is a play written by Arthur Miller in 1953. It is based
on the events surrounding the 1692 witch trials of Salem, Massachusetts.
