Epic theatre (German: episches Theater) is a theatrical movement arising 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 a new political theatre. These practitioners included Erwin Piscator, Vladimir Mayakovsky, Vsevolod Meyerhold and, most famously, Bertolt Brecht.
The term "epic theatre" comes from Erwin Piscator who coined it during his first year as director of Berlin's Volksbühne (1924—1927). Piscator aimed to encourage playwrights to address issues related to "contemporary existence." This new subject matter would then be staged by means of documentary effects, audience interaction, and strategies to cultivate an objective response. The epic form describes both a type of written drama and a methodological approach to the production of plays: "Its qualities of clear description and reporting and its use of choruses and projections as a means of commentary earned it the name 'epic'." Epic theatre incorporates a mode of acting that utilises what Brecht calls gestus. One of Brecht's most-important aesthetic innovations prioritised function over the sterile opposition between form and content. Brecht discussed the priorities and approach of epic theatre in his work "A Short Organum for the Theatre". Although many of the concepts and practices involved in Brechtian epic theatre had been around for years, even centuries, Brecht unified them, developed the approach, and popularised it.
Near the end of his career, Brecht preferred the term "dialectical theatre" to describe the kind of theatre he pioneered. From his later perspective, the term "epic theatre" had become too formal a concept to be of use anymore. According to Manfred Wekwerth, one of Brecht's directors at the Berliner Ensemble at the time, the term refers to the "'dialecticising' of events" that this approach to theatre-making produces.
