What were strengths and what were the weakness of the Aztec and Inka civilization on the eve of their encounter with European societies?

The Aztec and Inca civilizations exhibited significant strengths, such as advanced agricultural practices, sophisticated political systems, and impressive architectural achievements, which supported large, organized populations and complex societies. However, they also faced weaknesses, including internal strife, reliance on tribute systems that could incite rebellion, and limited technological advancements compared to European military capabilities. Additionally, both empires were vulnerable to diseases brought by Europeans, which decimated their populations and weakened their social structures. This combination of strengths and vulnerabilities ultimately influenced their rapid decline following European contact.
