What conquistador is known for conquering the Aztecs?

Hernán Cortés is the conquistador known for conquering the Aztec Empire. He arrived in present-day Mexico in 1519 and, through a combination of military strategy, alliances with local tribes, and the impact of diseases brought by Europeans, he ultimately defeated the Aztecs and captured their capital, Tenochtitlán, in 1521. His conquest significantly altered the course of history in the Americas and led to Spanish colonization.
