In the year 49 BCE, the Roman Senate declared Julius Caesar the enemy of the people of Rome (hostis publicus).

An Enemy of the People (original Norwegian title: En folkefiende) is an 1882 play by Norwegian playwright Henrik Ibsen that explores the conflict between personal integrity and societal norms. The play centers on Dr. Thomas Stockmann, who discovers a serious contamination issue in his town's new spas, endangering public health. His courageous decision to expose this truth brings severe backlash from local leaders, including his brother Peter Stockmann, who is a powerful political figure in the town.

Set against the backdrop of a community grappling with economic and environmental concerns, the play highlights the often harsh consequences faced by those who challenge established systems. Ibsen’s depiction of this struggle emphasizes the tension between truth and expediency. The character of Peter Stockmann is based on Ibsen’s own uncle, Christian Cornelius Paus, whose political influence and authoritative role in Ibsen's hometown of Skien parallel those of Peter in the play. Ibsen himself was uncertain about the play's classification, noting in a letter to his publisher that it contained both comedic and serious elements, reflecting his complex view of the protagonist's moral stance. This exploration of moral and societal conflict follows Ibsen’s earlier work, Ghosts, which faced similar criticism for its bold critique of societal norm
