The Persecution and Assassination of Marat as Performed by the Inmates of the Asylum of Charenton Under the Direction of the Marquis de Sade 1965

The Persecution and Assassination of Jean-Paul Marat as Performed by the Inmates of the Asylum of Charenton Under the Direction of the Marquis de Sade (German: Die Verfolgung und Ermordung Jean Paul Marats dargestellt durch die Schauspielgruppe des Hospizes zu Charenton unter Anleitung des Herrn de Sade), usually shortened to Marat/Sade (pronounced: [ma.ʝa.sad]), is a 1963 play by Peter Weiss. The work was first published in German.

Incorporating dramatic elements characteristic of both Artaud and Brecht, it is a bloody and unrelenting depiction of class struggle and human suffering which asks whether true revolution comes from changing society or changing oneself.
