Friedenstag

Friedenstag (Peace Day) is an opera in one act by Richard Strauss, his Opus 81, to a German libretto by Joseph Gregor. Strauss had hoped to work again with Stefan Zweig on a new project after their previous collaboration of Die schweigsame Frau, but the Nazi authorities had harassed Strauss over his collaboration with Zweig, who was of Jewish ancestry. While the idea for the story was from Zweig, he then suggested Gregor as a "safe" collaborator for the actual writing of the libretto. Zweig's influence on the work nonetheless remained in its "form and dramatic substance".
