A Doll's House was published in 1879. The play is a scathing criticism of the marital roles accepted by men and women which characterized Ibsen's society. I taught this at the University of the Sciences as an adjunct and I truly enjoyed it with the students as the first Realist play we covered.

Ghosts followed in 1881, another scathing commentary on the morality of Ibsen's society, in which a widow reveals to her pastor that she had hidden the evils of her marriage for its duration. The pastor had advised her to marry her fiancé despite his philandering, and she did so in the belief that her love would reform him. But his philandering continued right up until his death, and his vices are passed on to their son in the form of syphilis. The mention of venereal disease alone was scandalous, but to show how it could poison a respectable family was considered intolerable.

In An Enemy of the People (1882), Ibsen went even further. In earlier plays, controversial elements were important and even pivotal components of the action, but they were on the small scale of individual households. In An Enemy, controversy became the primary focus, and the antagonist was the entire community. One primary message of the play is that the individual, who stands alone, is more often "right" than the mass of people, who are portrayed as ignorant and sheeplike. Contemporary society's belief was that the community was a noble institution that could be trusted, a notion Ibsen challenged. In An Enemy of the People, Ibsen chastised not only the conservatism of society, but also the liberalism of the time. He illustrated how people on both sides of the social spectrum could be equally self-serving. An Enemy of the People was written as a response to the people who had rejected his previous work, Ghosts. The plot of the play is a veiled look at the way people reacted to the plot of Ghosts. The protagonist is a physician in a vacation spot whose primary draw is a public bath. The doctor discovers that the water is contaminated by the local tannery. He expects to be acclaimed for saving the town from the nightmare of infecting visitors with disease, but instead he is declared an 'enemy of the people' by the locals, who band against him and even throw stones through his windows. The play ends with his complete ostracism. It is obvious to the reader that disaster is in store for the town as well as for the doctor.

In 1896, he published John Gabriel Borkman.
