The Spanish conquest of Mexico, led by Hernán Cortés from 1519 to 1521, marked a pivotal moment in world history. This clash between the Spanish conquistadors and the Aztec Empire, ruled by Moctezuma II, resulted in the fall of Tenochtitlan and the establishment of Spanish colonial rule. The conquest was driven by a complex mix of motives, including the search for wealth, religious zeal, and imperial expansion. It involved key strategies like forming alliances with indigenous groups, exploiting internal conflicts, and leveraging technological advantages, ultimately reshaping the cultural, social, and political landscape of Mexico.
