The Chieftain is a two-act comic opera by Arthur Sullivan and F. C. Burnand based on their 1867 opera, The Contrabandista. It consists of substantially the same first act as the 1867 work with a completely new second act. It premiered at the Savoy Theatre on December 12, 1894, under the management of Richard D'Oyly Carte, for a run of 97 performances (by Sullivan's standards, a flop).
The opening cast included Florence St. John, Courtice Pounds, Walter Passmore, Richard Temple, Scott Russell, Florence Perry, Emmie Owen, R. Scott Fishe and Rosina Brandram.
In 1894, impresario Richard D'Oyly Carte needed a new piece for the Savoy Theatre. Gilbert and Sullivan's Utopia Limited had closed in June after a comparatively short (by G&S standards) nine-month run. André Messager's Mirette was an unsuccessful stop-gap, and Carte had to close the theatre in August. Desperate for a new work, he commissioned Sullivan and Burnand to patch up The Contrabandista, which could be made ready much faster than a new opera. Mirette was revised and re-opened in October for another two months, and although Mirette was playing strongly, once The Chieftain was ready in December, Mirette was closed, and The Chieftain was mounted.
