Although Verdi began sketching the music for "Il corsaro" in 1846, a lengthy illness forced him to postpone further work. He finally completed the score in early 1848, but the revolutions of that year delayed its first performance. When it finally premiered on 25 October at the Teatro Grande of Trieste Verdi was in Paris and did not participate as usual in the production, which was poorly received. Though more successful in subsequent stagings, "Il corsaro" was soon eclipsed by the operas of the noted "trilogy" and fell from the repertory.
