Catholic historical work examining the Spanish conquest of Mexico, the encounter between Spanish and Aztec cultures, and the events surrounding the apparition of Our Lady of Guadalupe to St. Juan Diego. Carroll presents the story from a distinctly Catholic perspective, combining historical narrative, eyewitness accounts, and religious interpretation.

Originally published in 1983 by Christendom Press, this paperback explores the fall of the Aztec Empire, the role of Hernán Cortés, the conversion of indigenous peoples, and the enduring significance of the Guadalupe apparition in the history of the Americas. The author, best known for his acclaimed History of Christendom series, aims to reassess conventional interpretations of the conquest and its religious consequences.
