Bertolt Brecht was a German playwright who developed Epic Theatre, which aimed to make audiences think critically rather than simply accept what they saw on stage. He was interested in Marxism and how industrialization affected society. To achieve his goal, Brecht used techniques like Verfremdungseffekt ("alienation effect") to remind viewers they were watching a play, not becoming absorbed in the story. This prevented emotional engagement and encouraged questioning the ideas presented. His unconventional approach revolutionized theater by transforming it into a medium for examining social issues.
