The Aztec were very strict with social classes. The upper class and the lower class were not to mix. As the years went on the gap between the social classes grew. This growth was caused by Itzcoatl giving some of his close friends and family large areas of land. Farmers were the largest part of society, by far. This group was also called Macehualtin and had half of their people in the lower class and half in the higher class. The part in the lower class was the group that did the field work. The higher class farmers were the ones that seeded and transplanted. The most important group on the Aztec social pyramid was the Calpalli. This social group was connected by either blood, or long association. They controlled the distribution of the land.
