Ghosts is a controversial three-act play by Henrik Ibsen that confronts taboo subjects such as inherited sin, illness, hypocrisy, and moral decay. Mrs. Alving, the central character, faces the tragic consequences of concealing the truth about her late husband from their son. Shocking for its time, Ghosts challenged the foundations of 19th-century morality and social convention. Its unflinching look at family, duty, and repression continues to provoke and move audiences more than a century later.
