Rescue opera was a genre of opera in the late 18th and early 19th centuries in France and Germany. Generally, rescue operas deal with the rescue of a main character from danger and end with a happy dramatic resolution in which lofty humanistic ideals triumph over base motives. Operas with this kind of subject matter became popular in France around the time of the French Revolution; a number of such operas dealt with the rescue of a political prisoner. Stylistically and thematically, rescue opera was an outgrowth of the French bourgeois opéra comique; musically, it began a new tradition that would influence German Romantic opera and French grand opera. The most famous rescue opera is Ludwig van Beethoven's Fidelio.
