Díaz's monumental work, The True History of the Conquest of New Spain (Historia verdadera de la conquista de la Nueva España, 1632), is a firsthand account of the conquest of Mexico from 1514 to 1568. In a fresh, natural way, Díaz described both great events and the daily life of the common soldier.
Díaz participated in several military campaigns in the New World and from 1519 to 1521 was with Hernando Cortez in the conquest of Mexico. Late in life, Díaz settled in Guatemala.
