Don Carlos is a five-act grand opera composed by Giuseppe Verdi to a French-language libretto by Joseph Méry and Camille du Locle, based on the dramatic play Don Carlos, Infant von Spanien (Don Carlos, Infante of Spain) by Friedrich Schiller.
Given its premiere at the Salle Le Peletier on March 11, 1867, the opera's story is based on conflicts in the life of Carlos, Prince of Asturias (1545–1568), after his betrothed Elisabeth of Valois was married instead to his father Philip II of Spain as part of the peace treaty ending the Italian War of 1551–1559 between the Houses of Habsburg and Valois. It was commissioned and produced by the Théâtre Impérial de l'Opéra (Paris Opera). This 1971 EMI recording stars Placido Domingo. Carlo Maria Giulini conducts.
