What happened to Aztec's extinction?

Answer 1

The Aztecs never went extinct.

The Spaniards did however end their reign of power through a combination of religious, psychological, linguistic, and germ warfare. The Aztecs had no natural defense against these diseases, which were the main cause for their downfall.

In total, European diseases and slavery wiped out 90% of America's Native population, which was equivalent to 10% of planet Earth's population. Much greater then the entire continent of Europe. The Aztecs did not die out however, they just became ruled by the Spaniards.

In addition, the Aztecs did not call themselves 'Aztecs', they called themselves Mexicas.

The modern day Mexicans are either full blooded Aztecs, Mayans, Zapotec, Mixtec, or Meztiso (of mixed blood). Spanish only comprises of 10% of Mexico's population.

The Aztecs are still alive and festivals are held to this day. Although Mexicans speak Spanish, the majority of them are natives. Some in fact still speak their native Mexica language of Nahuatl. The true language of the Mexicans.
