The Nutcracker and the Mouse King is a story written in 1816 by E. T. A. Hoffmann in which young Marie Stahlbaum's favorite Christmas toy, the Nutcracker, comes alive and, after defeating the evil Mouse King in battle, whisks her away to a magical kingdom populated by dolls. In 1892, the Russian composer Pyotr Ilyich Tchaikovsky and choreographers Marius Petipa and Lev Ivanov turned Alexandre Dumas père's adaptation of the story into the ballet The Nutcracker, which became one of Tchaikovsky's most famous compositions, and perhaps the most popular ballet in the world..
