When Nora Helmer closed the door on her doll's house, the modern drama came into being.  It was not so much that she asserted her emancipation from monogamy but that Henrik Ibsen himself proclaimed the playwright’s emancipation from the anemic drama of his time.  Ghosts, An Enemy of the People and The Master Builder advanced the Liberation in terms of social drama which revealed human beings confronted with present-day Problems.
