How were Medieval Europe and the Aztecs similar?

Medieval Europe and the Aztecs shared similarities in their social structures, both featuring a rigid hierarchy with a ruling elite at the top—nobility and monarchs in Europe, and emperors and nobles in Aztec society. Both cultures emphasized the importance of religion, with the Aztecs practicing human sacrifice to appease their gods, while medieval Europeans engaged in various religious rituals and conflicts, including the Crusades. Additionally, both societies had economies based on agriculture and relied on a system of tribute or feudal obligations to sustain their populations and maintain their political power.
