Ludovic Halévy in the context of Georges Bizet

Carmen (French: [kaʁmɛn] ) is an opera in four acts by the French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halévy, based on the novella of the same title by Prosper Mérimée. The opera was first performed by the Opéra-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalised its first audiences. Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years. Carmen has since become one of the most popular and frequently performed operas in the classical canon; the "Habanera" and "Seguidilla" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias.

The opera is written in the genre of opéra comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don José, a naïve soldier who is seduced by the wiles of the fiery gypsy Carmen. José abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which José kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the murder of the main character on stage, broke new ground in French opera and were highly controversial.

Henri Meilhac (French pronunciation: [ɑ̃ʁi mɛjak]; 23 February 1830 – 6 July 1897) was a prolific French playwright and opera librettist, known for his collaborations with Ludovic Halévy on comic operas with music by Jacques Offenbach. He also wrote occasionally for serious works including Georges Bizet's Carmen (with Halévy) and Jules Massenet's Manon.

Born in Paris, Meilhac began writing for a humorous magazine in 1852, and four years later he began a career as a playwright. In 1860 he collaborated for the first time with Halévy, an old schoolfriend, on a one-act comedy, presented at the Théâtre des Variétés. Over the next twenty-one years the two co-wrote fifty more stage works.

The Toreador Song, also known as the Toreador March or March of the Toreadors, is the popular name for the 1875 aria "Votre toast, je peux vous le rendre" ("I return your toast to you"), from the French opera Carmen, composed by Georges Bizet to a libretto by Henri Meilhac and Ludovic Halévy. It is sung by the bullfighter (French: toréador) Escamillo as he enters in act 2 and describes various situations in the bullring, the cheering of the crowds and the fame that comes with victory. The refrain, "Toréador, en garde", forms the middle part of the prelude to act 1 of Carmen.
