Roberto Devereux (or "Roberto Devereux, ossia Il conte di Essex" ["Robert Devereux, or the Earl of Essex"]) is a "tragedia lirica", or tragic opera, by Gaetano Donizetti.
 Salvadore Cammarano wrote the Italian libretto after François Ancelot's tragedy "Elisabeth d'Angleterre" (1829), and based as well on the "Historie secrete des amours d'Elisabeth et du comte d'Essex" (1787) by "Jacques Lescéne des Maisons", although Devereux was the subject of at least two other French plays: "Le Comte d'Essex" by Thomas Corneille and "Le Comte d'Essex" by Gauthier de Costes, seigneur de la Calprenède.
Operas set against the background of the medieval Crusades can be found in the earliest examples of the art form and continue to be written into the 21st century.
 Many of the works listed here contain characters and plots based on real or legendary figures of the time such as Tancred, Prince of Galilee, Godfrey of Bouillon or Jaufre Rudel.
 The majority are set, at least in part, in the Holy Land and the surrounding region and deal with the conflicts between the Christians and Muslims. Others, such as Donizetti's "Gabriella di Vergy", deal with the misadventures of knights returning from the Crusades.
 In the case of "Gabriella di Vergy", Raoul de Coucy returns from the Third Crusade to find that his beloved Gabriella has married Lord Fayel.
 Following a duel, Fayel cuts out the heart of the unfortunate Raoul and presents it in an urn to Gabriella.
 The only comedy in the list, Rossini's "Le comte Ory", recounts the attempts by Ory and his friends to seduce the Countess of Formoutiers and the women of her household while their men are away at the Crusades.
 Ory's ploy of dressing up as nuns to gain access to the women is foiled when the Crusaders return.
 Many of the libretti for the operas listed are based either directly or indirectly on Torquato Tasso's epic poem, "La Gerusalemme liberata" ("Jerusalem Delivered"), or on Voltaire's tragic play, "Zaïre".
