Originally choreographed by Julius Reisinger to the music of Pyotr Ilyich Tchaikovsky (opus 20), it was first presented as "The Lake of the Swans" by the Ballet of the Moscow Imperial Bolshoi Theatre on 20 February/4 March 1877 (Julian/Gregorian calendar dates) in Moscow, Russia.  Although the ballet is presented in many different versions, most ballet companies today base their stagings both choreographically and musically on this revival by Marius Petipa and Lev Ivanov, staged for the Imperial Ballet, first presented on 15 January/27 January 1895, at the Imperial Mariinsky Theatre in St. Petersburg, Russia instead of the original version.

Vaclav (Wentsel), or Jules or Julius Wentsel Reisinger (1828 – 1892) is paradoxical figure in the history of ballet.  This prolific choreographer, an author of more than twenty works on various European stages, directed the Moscow company of the Bolshoi Theatre.  He is linked with two memorable events: the first stage production of Tchaikovsky's ballet "Swan Lake" and the production of the first ballet performance for the opening of the Prague National Theatre in 1884.  His work on "Swan Lake" was considered unsuccessful by the critics of the day but not necessarily unsuccessful by the theatre-going public—after all, Reisinger's original production of "Swan Lake" was kept in the active repertoire of the Bolshoi Theatre for seven years and was performed over thirty times during a period when other ballets could not sustain even twenty performances.  In fact, the production was not pulled until the scenery and costumes were worn and threadbare.  Much of its popularity was assumably due to its beautiful musical score which was critically acclaimed even though the choreography was not.
