La Conquista is an opera in two acts by Lorenzo Ferrero 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 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.

The musical language owes very little to ethnic influences, but the use of the Nahuatl language, characterized by the presence of distinct short and long vowels, imposes a specific rhythm to the vocal part.
