Iolanta

Iolanta, Op. 69, (Russian: Иоланта) is a lyric opera in one act by Pyotr Tchaikovsky. It was the last opera he composed. The libretto was written by the composer's brother Modest Tchaikovsky, and is based on the Danish play Kong Renés Datter (King René's Daughter) by Henrik Hertz, a romanticised account of the life of Yolande de Bar. In the original Danish play, the spelling of the princess's name was "Iolanthe", later adopted for the otherwise unrelated Gilbert and Sullivan operetta of that name. The play was translated by Fyodor Miller and adapted by Vladimir Zotov. The opera received its premiere on 18 December 1892 in Saint Petersburg.

Composed after the completion of The Queen of Spades, Tchaikovsky worried that he had lost his creative inspiration after such a large project. He started Iolanta with the final duet in June 1891, and despite his worries, finished composition in September and orchestration in November. The public reception was quite favorable, though Tchaikovsky was disappointed and felt he was repeating himself, especially when compared to his earlier work, The Enchantress.

The world premiere took place on 18 December (6 December O.S.) 1892 at the Mariinsky Theatre in Saint Petersburg. It was conducted by Eduard Nápravník and sets were designed by Mikhail Bocharov. The premiere of the opera shared a double bill with the composer's last ballet, The Nutcracker. A 1997 two-act version of Iolanta is performed regularly at the Bolshoi Theatre in Moscow, and in Belarus.
