Modernism emerged in the late 19th and early 20th centuries in response to industrialization, urbanization, and globalization. It challenged traditional artistic forms and sought new ways to express modern experiences. Modern drama developed as one manifestation of modernism in theatre. It shifted from plays focusing on external conflicts to exploring inner psychological aspects of characters. Modern drama experimented with forms like symbolism, expressionism, and the theatre of the absurd. Prominent modern dramatists include Henrik Ibsen, George Bernard Shaw, Anton Chekhov, Eugene O'Neill, Samuel Beckett, Arthur Miller, and Tennessee Williams.
