The Norwegian playwright known for advocating for women's rights is Henrik Ibsen. His works, particularly A Doll's House, challenged societal norms and the roles of women in the 19th century. Ibsen's characters often explored themes of independence and self-discovery, reflecting the struggles faced by women in a patriarchal society. By portraying strong female protagonists who questioned their societal roles, Ibsen opened up discussions about gender equality and the need for social reform. His influence extends beyond theater, as he inspired feminist movements and thinkers around the globe.
