Die Walkre's well known section is the Ride of the Valkyries. Wagner moved his tale from the Norse mythology told in the Volsunga Saga and the Poetic Edda. It achieved its premiere at the National Theatre Munich on 26th June the year 1870 at the insistence of King Ludwig II of Bavaria. It released in Wagner's Bayreuth Festival as part of the complete cycle on 14th August in the year 1876. The opera made its United States (US) introduction at the Academy of Music in New York on 2nd April the year 1877.
The first act shows “It is the following morning. Siegmund and Sieglinde have fled from Hunding into the mountains. Wotan orders his daughter named Valkyrie to prepare for battle to help Siegmund kill Hunding in their expected fight. Fricka who is Wotan's companion, now approaches. As the guardian of marriage, she demands the death of the Siegmund, who is in crime of both adultery and incest. When the Wotan refuses to discard his "free hero", Fricka lays exposed his self-deception: Siegmund is in no wisdom independent since his fate has been preordained by Wotan, who has even circuitously led him to find the magic sword.
