Epic theatre is a theatrical movement that arose in the early to mid-20th century from the theories and practice of a number of theatre practitioners who responded to the political climate of the time through the creation of new political dramas. Epic theatre is not meant to refer to the scale or the scope of the work, but rather to the form that it takes. Epic theatre emphasizes the audience's perspective and reaction to the piece through a variety of techniques that deliberately cause them to individually engage in a different way. The purpose of epic theatre is not to encourage an audience to suspend their disbelief, but rather to force them to see their world as it is.

Friedrich Dürrenmatt was a Swiss author and dramatist. He was a proponent of epic theatre whose plays reflected the recent experiences of World War II. The politically active author's work included avant-garde dramas, philosophical crime novels, and macabre satire. Dürrenmatt was a member of the Gruppe Olten, a group of left-wing Swiss writers who convened regularly at a restaurant in the city of Olten.
