Eugene O’Neill’s *The Emperor Jones* is one of the earliest and most successful Expressionist plays in American drama.

In *The Emperor Jones*, O’Neill transforms the stage into a representation of Brutus Jones’s disturbed consciousness. The audience does not simply witness physical events but experiences Jones’s psychological journey as he escapes through the forest.
