calpulli

Nahuatl calpulli (from calli meaning 'house' and -pul an augmentative and -li a suffix) literally means 'big house' but describes something closer to a neighborhood or district. In Aztec society, the calpulli was the basic social, territorial, and administrative unit. Tenochtitlan was divided into multiple calpullis, each with clearly defined boundaries, shared land (milpas), a community temple (calpulco), and a school (telpochcalli).

Each calpulli functioned almost as a city-state within the larger Aztec state. Land was held communally by the calpulli, not by individuals. Families had usufruct rights—the right to use land they cultivated—but the calpulli itself owned the property. If you didn't farm it, another family could use it. This system prevented landlessness and created stability.

The calpulli had legal authority. They collected taxes, maintained order, and kept records. Young men trained in the telpochcalli received military and civic instruction. Women had separate but equally valued roles in crafts, weaving, and community work. The calpulli was not a clan based on bloodline but a neighborhood-corporation based on residence and shared labor.

Spanish colonizers misunderstood the calpulli completely. They imposed European feudal categories and Christian parish structures, destroying the system's elegant checks and balances. The neighborhoods were reorganized into parishes. The communal land was privatized. Within a century, the calpulli system was extinct. What had been shared became individual property. What had been balanced became hierarchical.
