Bertolt Brecht was a Marxist playwright who developed Epic Theatre, which sought to provoke rational self-reflection in audiences rather than emotional identification. Some key features of Epic Theatre included distancing effects to remind audiences the play was constructed, direct addresses to audiences to adopt a critical perspective, and a focus on argument over suggestion to move audiences to social action. Brecht employed techniques like placards, songs interrupting action, and past tense narration to achieve the "Verfremdungseffekt" or estrangement effect. He aimed to transform theatre into a forum for political ideas and critique of social realities through this modernist realism.
