What is the author's style in A Doll's House by Henrik Ibsen?

In this play, A Doll's House, Ibsen established a new genre of modern drama. Prior to A Doll's House, contemporary plays were usually historical romances or contrived comedy of manners. Ibsen is known as the "father of modern drama" because he elevated theatre from entertainment to a forum for exposing social problems. Ibsen broke away from the romantic tradition with his realistic portrayals of individual characters and his focus on psychological concerns as he sought to portray the real world, especially the position of women in society.
