The romantic era in ballet began with "The Ballet of the Nuns" in 1831 and was followed by "La Sylphide" in 1832. The genre began a slow decline. "Coppélia" of 1870 is said to mark the end of the romantic ballet, although the three ballets composed by Tchaikovsky are romantic ballets. Tchaikovsky's "Swan Lake" of 1876 is considered a romantic ballet. Even his "The Nutcracker" of 1892 is a romantic ballet. Michel Fokine's "Les Sylphides" of 1906 is considered a tribute to the romantic ballet in its atmosphere and tone.
