Detailed explanation-1: -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-2: -The overthrow of the Aztec Empire by Cortez and his expedition rests on three factors: The fragility of that empire, the tactical advantages of Spanish technology, and smallpox.

Detailed explanation-3: -Spanish conquistadores commanded by Hernán Cortés allied with local tribes to conquer the Aztec capital city of Tenochtitlán. 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.

Detailed explanation-4: -The main view is that the Inca were eventually defeated due to inferior weapons, ‘open battle’ tactics, disease, internal unrest, the bold tactics of the Spanish, and the capture of the Inca’s Emperor.
