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 Apolloin Rome on 17 February 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 IIIset 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.
