Now part of the canon of Italian plays, Morte accidentale di un anarchico, in its original form, was a subversive piece of political theatre. It is based on the events of December 1969 when Guiseppe Pinelli, the anarchist of the title, 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 the bomb 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 for sixth form and university students but will be useful to anyone who wants to read a salient text of the period with the help of notes and vocabulary.
