Die Walküre is the second of the four operas that form the cycle Der Ring des Nibelungen (The Ring of the Nibelung), by Richard Wagner. Die Walküre's best-known excerpt is the "Ride of the Valkyries".
Wagner took his tale from the Norse mythology told in the Volsunga Saga and the Poetic Edda.
It received its premiere at the National Theater in Munich on June 26, 1870 at the insistence of King Ludwig II of Bavaria. It premiered in Wagner's Bayreuth Festival as part of the complete cycle on August 14, 1876. The opera made its United States premiere at the Academy of Music in New York on April 2, 1877. This live 1993 Bayreuther production was conducted by Daniel Barenboim.
