The Nutcracker (Balet-feyeriya) is a two-act ballet, originally choreographed by Marius Petipa and Lev Ivanov with a score by Pyotr Ilyich Tchaikovsky (Op. 71). The libretto is adapted from E. T. A. Hoffmann's story "The Nutcracker and the Mouse King".

Although the original production was not a success, the 20-minute suite that Tchaikovsky extracted from the ballet was. However, the complete Nutcracker has enjoyed enormous popularity since the late 1960s and is now performed by countless ballet companies, primarily during the Christmas season, especially in North America. Major American ballet companies generate around 40% of their annual ticket revenues from performances of The Nutcracker. The ballet's score has been used in several film adaptations of Hoffmann's story.

Tchaikovsky's score has become one of his most famous compositions. Among other things, the score is noted for its use of the celesta, an instrument that the composer had already employed in his much lesser known symphonic ballad The Voyevoda.

After the success of The Sleeping Beauty in 1890, Ivan Vsevolozhsky, the director of the Imperial Theatres, commissioned Tchaikovsky to compose a double-bill program featuring both an opera and a ballet. The opera would be Iolanta. For the ballet, Tchaikovsky would again join forces with Marius Petipa, with whom he had collaborated on The Sleeping Beauty. The material Petipa chose was an adaptation of E. T. A. Hoffmann's story "The Nutcracker and the Mouse King", by Alexandre Dumas called "The Story of a Nutcracker". The plot of Hoffmann's story (and Dumas' adaptation) was greatly simplified for the two-act ballet. Hoffmann's tale contains a long flashback story within its main plot titled "The Tale of the Hard Nut", which explains how the Prince was turned into the Nutcracker. This had to be excised for the ballet.

Petipa gave Tchaikovsky extremely detailed instructions for the composition of each number, down to the tempo and number of bars. The completion of the work was interrupted for a short time when Tchaikovsky visited the United States for twenty-five days to conduct concerts for the opening of Carnegie Hall. Tchaikovsky composed parts of The Nutcracker in Rouen, France.

Saint Petersburg premiere

The first performance of the ballet was held as a double premiere together with Tchaikovsky's last opera, Iolanta, on 18 December 1892, at the Imperial Mariinsky Theatre in Saint Petersburg, Russia. Although the libretto was by Marius Petipa, who exactly choreographed the first production has been debated. Petipa began work on the choreography in August 1892; however, illness removed him from its completion and his assistant of seven years, Lev Ivanov, was brought in. Although Ivanov is often credited as the choreographer, some contemporary accounts credit Petipa. The performance was conducted by Italian composer Riccardo Drigo, with Antonietta Dell'Era as the Sugar Plum Fairy, Pavel Gerdt as Prince Coqueluche, Stanislava Belinskaya as Clara, Sergei Legat as the Nutcracker-Prince, and Timofey Stukolkin as Drosselmeyer. Unlike in many later productions, the children's roles were performed by real children – students of the Imperial Ballet School in Saint Petersburg, with Belinskaya as Clara, and Vassily Stukolkin as Fritz – rather than adults.

The first performance of The Nutcracker was not deemed a success. The reaction to the dancers themselves was ambivalent. While some critics praised Dell'Era on her pointework as the Sugar Plum Fairy (she allegedly received five curtain-calls), one critic called her "corpulent" and "podgy". Olga Preobrajenskaya as the Columbine doll was panned by one critic as "completely insipid" and praised as "charming" by another.

Alexandre Benois described the choreography of the battle scene as confusing: "One can not understand anything. Disorderly pushing about from corner to corner and running backwards and forwards – quite amateurish."

The libretto was criticized as "lopsided" and for not being faithful to the Hoffmann tale. Much of the criticism focused on the featuring of children so prominently in the ballet, and many bemoaned the fact that the ballerina did not dance until the Grand Pas de Deux near the end of the second act (which did not occur until nearly midnight during the program). Some found the transition between the mundane world of the first scene and the fantasy world of the second act too abrupt. Reception was better for Tchaikovsky's score. Some critics called it "astonishingly rich in detailed inspiration" and "from beginning to end, beautiful, melodious, original, and characteristic". But this also was not unanimous as some critics found the party scene "ponderous" and the Grand Pas de Deux "insipid".
