Erwin Friedrich Maximilian Piscator was a German theatre director and producer. Along with Bertolt Brecht, he was the foremost exponent of epic theatre, a form that emphasizes the socio-political content of drama, rather than its emotional manipulation of the audience or the production's formal beauty.

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.
