The Calpulli. After the family, the basic unit of ancient Aztec government was the calpulli. Families didn't individually own land, the land was owned by a group of families, the calpulli. This structure of local government existed long before the Aztec empire. The leadership in the calpulli would be responsible for the basic needs of the group.
Crops. The most common crop grown by the Aztecs was maize, also known as corn, and it was also the most important. Maize could be stored for long periods of time, and in addition to being eaten as it was, it could be ground into flour and made into other foods. Squash was another important crop in Aztec agriculture. There are many varieties of squash that were utilized by Aztec farmers based on how they could be best used as a food source. The pumpkin, for example, was used often because its seeds provided a great deal of protein.
