In Aztec society, a family group was commonly referred to as a calpulli. The calpulli was not just a typical family unit; it represented a broader social structure. It included extended families and was responsible for various aspects of life including the sharing of land, religious practices, and community responsibilities.
Members of a calpulli lived together, and each calpulli had its own leaders and governed its own activities. This system allowed for a strong sense of community and mutual support among its members, which was crucial in a society that relied heavily on agriculture and trade. The calpulli also played a significant role in the Aztec economy and education, as they managed the land for farming and passed down cultural knowledge to the younger generations.
