Un ballo in maschera (A Masked Ball) is an 1859 opera in three acts by Giuseppe Verdi. The text by Antonio Somma was based on Eugène Scribe's libretto for Daniel Auber's 1833 five act opera, Gustave III, ou Le bal masqué.
The plot concerns the assassination in 1792 of King Gustav III of Sweden who was killed as the result of a political conspiracy against him. He was shot while attending a masked ball and died of his wounds thirteen days later.
It was to take over two years between the time of the commission from Naples and planned for a production there and its premiere performance at the Teatro Apollo in Rome on February 17, 1859. In order to become the Un ballo in maschera which we know today, Verdi's opera (and his libretto) was forced to undergo a significant series of transformations and title changes. Based on the Scribe libretto and begun as Gustavo III set in Stockholm, it became Una vendetta in domino set in Stettin, and finally Un ballo in maschera set in Boston during the colonial era. These changes were caused by a combination of censorship regulations in both Naples and Rome, as well as by the political situation in France in January 1858. It became one of the most frustrating experiences of Verdi's career.
From the mid-20th century, it has become more common for the setting to revert to its original 18th-century Stockholm location. A re-creation of the original Gustavo III has been staged in Sweden.
