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. The opera is most often performed in Italian translation, usually under the title Don Carlo.
The opera's story is based on conflicts in the life of Carlos, Prince of Asturias (1545–1568). Though he was betrothed to Elisabeth of Valois, part of the peace treaty ending the Italian War of 1551–59 between the Houses of Habsburg and Valois demanded that she be married instead to his father Philip II of Spain. It was commissioned and produced by the Théâtre Impérial de l'Opéra (Paris Opera) and given its premiere at the Salle Le Peletier on March 11, 1867.
