How was Ibsen influential in the drama world?

Henrik Ibsen is often regarded as the father of modern drama due to his pioneering use of realism and his exploration of complex social issues. He shifted the focus of theater from grand historical themes to the psychological struggles of individuals, particularly regarding gender roles, morality, and societal constraints. His plays, such as "A Doll's House" and "Hedda Gabler," challenged conventional narratives and inspired future playwrights to address contemporary issues and develop more nuanced characters. Ibsen's emphasis on character-driven plots and open-ended conclusions significantly transformed theatrical storytelling.
