What Native American civilization was destroyed by Hern?

Hernán Cortés is most famously known for the destruction of the Aztec civilization in the early 16th century. He led the Spanish expedition that resulted in the fall of Tenochtitlán, the Aztec capital, in 1521. This conquest was marked by violence, betrayal, and the spread of diseases that devastated the indigenous population. The fall of the Aztecs paved the way for Spanish colonization in Mexico.
