Did the Spanish won the Aztecs?

Yes, the Spanish conquistadors, led by Hernán Cortés, defeated the Aztec Empire in the early 16th century. The conquest culminated in 1521 when Cortés captured Tenochtitlán, the Aztec capital, after a series of battles, alliances with rival indigenous groups, and the spread of diseases that weakened the Aztec population. This marked the beginning of Spanish colonial rule in Mexico.
