What is Ludwig van Beethoven’s only opera?

Ludwig van Beethoven’s only opera is Fidelio.12

First performed in 1805, the work underwent several revisions before reaching its final form in 1814. The opera, which is based on a libretto inspired by French Revolutionary-era literature, tells the story of a woman named Leonore who disguises herself as a man named Fidelio to rescue her husband from political imprisonment. Despite initial struggles to find success, Fidelio eventually became a classic of the German theatre, celebrated for its grandeur and its powerful theme regarding the triumph of the human spirit over oppression.12
