USA HISTORY

Detailed explanation-1: -The Aztec had no immunity to European diseases. Smallpox spread among the indigenous people and crippled their ability to resist the Spanish. The disease devastated the Aztec people, greatly reducing their population and killing an estimated half of Tenochtitlán’s inhabitants.

Detailed explanation-2: -Cortés’s army besieged Tenochtitlán for 93 days, and a combination of superior weaponry and a devastating smallpox outbreak enabled the Spanish to conquer the city. Cortés’s victory destroyed the Aztec empire, and the Spanish began to consolidate control over what became the colony of New Spain.

Detailed explanation-3: -The Spanish were able to defeat the Aztec and the Inca not only because they had horses, dogs, guns, and swords, but also because they brought with them germs that made many native Americans sick. Diseases like smallpox and measles were unknown among the natives; therefore, they had no immunity to them.

Detailed explanation-4: -The Spanish had a positive effect on Aztec civilization because they helped modernize the society. They introduced the Aztecs to domestic animals, sugar, grains, and European farming practices. Most significantly, the Spanish ended the Aztec’s practice of human sacrifice.

Detailed explanation-5: -In May 1521, Cortés returned to Tenochtitlán, and after a three-month siege the city fell. This victory marked the fall of the Aztec empire. Cuauhtémoc, Cuitláhuac’s successor as emperor, was taken prisoner and later executed, and Cortés became the ruler of a vast Mexican empire.
