The Duchess of Padua is a tragic melodrama that centres around a young man named Guido Ferranti who has come to Padua to learn the secret of his birth. There he is told that his father's life was ruined by the current duke of Padua; Guido is convinced that he should revenge his father's life by murdering the duke. He agrees at first to undertake this mission, but later balks at the task, only for it to be carried out by his lover, Beatrice, the wife of the murdered Duke. The play ends in further bloodshed, with the double suicide of the lovers.
The Duchess of Padua, written in 1883, is Oscar Wilde's second play. Written for, but ultimately rejected by, the American actress Mary Anderson, it finally premiered anonymously at the Broadway Theatre in New York.
