Why did audiences riot at performances of The Playboy of the Western World?

Audiences rioted at performances of J.M. Synge’s The Playboy of the Western World primarily because they were enraged by the play’s satire of Irish character and rural life.12

Specifically, the play’s portrayal of the Irish peasantry and its mockery of Irish braggadocio caused significant resentment among viewers. The work, a masterpiece of the Irish literary renaissance, centers on a character who gains local admiration after claiming to have murdered his father, only for the community to turn on him when the father appears alive.12

These riots occurred during the play's 1907 opening at the Abbey Theatre in Dublin and followed the production to the United States, where similar protests and disorders broke out in cities with large Irish American communities, including New York City and Philadelphia.12
