La Conquista is an opera in two acts by Lorenzo Ferrero set to a trilingual libretto by the composer and Frances Karttunen, based on a concept by Alessandro Baricco. It depicts the major episodes of the Spanish conquest of the Aztec Empire in 1521 and the subsequent destruction of the Aztec civilization. The libretto (English-Spanish-Nahuatl) is a blend of historical and literary sources drawn from transcriptions of indigenous and European literature, both kept, with some exceptions, in their original languages. The texts are taken from The Truthful History of the Conquest of New Spain by Bernal Díaz del Castillo, the Book XII of the Florentine Codex, the works of Juan Boscán Almogáver, Bernardino de Sahagún, Lope de Vega, Heinrich Heine, and from Aztec prayers, songs and poems as collected in Cantares Mexicanos and Romances de los señores de Nueva España.

Lorenzo Ferrero is an Italian composer, librettist, author, and book editor. He started composing at an early age and has written over a hundred compositions thus far, including twelve operas, three ballets, and numerous orchestral, chamber music, solo instrumental, and vocal works. His musical idiom is characterized by eclecticism, stylistic versatility, and a neo-tonal language.
