Why does Doctor Stockmann become an enemy of the people in Henrik Ibsen’s An Enemy of the People?

In Henrik Ibsen’s play An Enemy of the People, Doctor Thomas Stockmann is declared an enemy of the people because he refuses to remain silent about a public health crisis.1

As the medical officer for his town’s public baths, Stockmann discovers that the water is contaminated. Because the town’s prosperity relies heavily on these baths, local authorities and citizens view his findings as a threat to their economic interests. Stockmann’s insistence on exposing the truth, despite the pressure to suppress it for the sake of the town's financial stability, leads to his ostracization. Through this character, Ibsen emphasizes the moral principle that the pursuit of truth is more important than seeking popular approval or maintaining social convenience.1
