Hernán Cortés de Monroy y Pizarro Altamirano, 1st Marquess of the Valley of Oaxaca (1485-1547) was a Spanish conquistador who led an expedition that caused the fall of the Aztec Empire and brought large portions of what is now mainland Mexico under the rule of the King of Castile in the early 16th century.

The Spanish conquest of the Aztec Empire was a pivotal event in the history of the Americas, marked by the collision of the Aztec Triple Alliance and the Spanish Empire, ultimately reshaping the course of human history. Taking place between 1519 and 1521, this event saw the Spanish conquistador Hernán Cortés, and his small army of soldiers and indigenous allies, overthrowing one of the most powerful empires in Mesoamerica.
