Pedro de Alvarado was a Spanish conquistador and governor of Guatemala. He participated in the conquest of Cuba, in Juan de Grijalva's exploration of the coasts of the Yucatán Peninsula and the Gulf of Mexico, and in the conquest of the Aztec Empire led by Hernán Cortés. He is considered the conquistador of much of Central America, including Guatemala, Honduras, and El Salvador.

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.
