One reason why the Spanish easy Concord Americans was that the Aztecs and Incas lacked what?

Answer 1

One reason why the Spanish easily conquered the Aztecs and Incas was that these civilizations lacked immunity to diseases brought by the Europeans, such as smallpox and influenza. The indigenous populations had no prior exposure to these diseases and thus had no natural immunity, leading to devastating epidemics that weakened their societies and contributed to the Spanish conquest. Additionally, the Aztecs and Incas were also affected by internal strife and rivalries, which the Spanish were able to exploit.
