The Russian city has been one of the world's ballet capitals for almost two centuries. It is home to the Bolshoi Ballet, founded in the late 18th century and based at the Bolshoi Theatre. This is the city where Petipa's Don Quixote was first performed, also the site, in 1877, of the notorious first production of Reisinger's and Tchaikovsky's Swan Lake. The other major company is the Stanislavsky Ballet which is based at Moscow's second opera house. During the 20th century, under the Communists, ballet in Moscow was well supported by the state and it was here that the heroic Soviet style flourished. In the late 1980s and early 1990s, small independent companies, such as Moscow City Ballet and Moscow Classical Ballet, began to proliferate as well as a small number of modern dance groups. Since 1969 the city has hosted an International Ballet Competition, which takes place every four years. See also Russia.
