And one more thing, Can you describe the social class of the aztec empire???

"Social classes in Aztec culture

There were two main social classes in Aztec culture. First the nobility or pilli, then the common people or macehualli. Each of these was further broken up into groups of people that had quite different lives.

There were also slaves, which were generally well-treated. Slavery was not hereditary - the children of a slave were free. There were ways for a slave to gain freedom, such as purchasing it."
