From the later 1920s, Brecht developed a Marxist critique of the theater apparatus and began to experiment on the margins of, and outside, commercial theater. It was not until after World War II, when he founded the Berliner Ensemble, that he finally had the opportunity to control the means of theatrical production. The Berliner Ensemble’s entire approach was underpinned by a holistic understanding of political theater. This extended from actor training to outreach activities with audiences, going far beyond the argument or subject matter of any individual play.
