Now part of the canon of the Italian stage, Morte accidentale di un anarchico was in its original form a subversive piece of political theatre. The play is based on the events of December 1969 when Guiseppe Pinelli, the anarchist, "fell" to his death from a fourth floor window of the police headquarters in Milan where he was being held for questioning in connection with a bombing in Pialla Fontana. This edition sets the play in its historical and political context and introduces readers to Fo's political thought and theatrical practice. The text has been edited and annotated for classroom use, but the play itself will be of interest to readers outside the classroom as well.
