A fairy tale-ballet in two acts of Alexandre Dumas père's adaptation of the story "The Nutcracker and the Mouse King" by E.T.A. Hoffmann.
The story has been published in many book versions including colourful children-friendly versions. The plot revolves around a German girl named Clara Stahlbaum or Clara Silverhaus. In some Nutcracker productions, Clara is called Marie. (In Hoffmann's tale, the girl's name actually is Marie or Maria, while Clara - or "Klärchen" - is the name of one of her dolls.)
