Originally titled Historia Verdadera de la Conquista de la Nueva Espa a (The True History of the Conquest of New Spain), this first-person narrative by the military adventurer, conquistador, and settler Bernal D az del Castillo (1492-1584) recounts the fall of Aztec Emperor Moctezuma II, the defeat of the Aztec Empire, and his participation in the Spanish military campaigns that brought them about. D az served in three Mesoamerican expeditions, that of Francisco Hern ndez de C rdoba to the Yucat n peninsula (1517); that of Juan de Grijalva (1518), and finally the expedition of Hern n Cort s (1519) in the Valley of Mexico. Amongst chroniclers, D az was most celebrated as Daniel Defoe (1660-1731) was amongst novelists.
