Middle Formative period

Mesoamerican history

Quick Summary

The Middle Formative period in Mesoamerican history, spanning from 900 to 300 BCE, saw the development of settled village life and the beginnings of more complex societal structures. While cultures in central Mexico, such as those in the Valley of Mexico, were characterized by simple villages and plain pottery, evidence suggests the emergence of ceremonial pyramid construction at sites like Cuicuilco.1

Olmec influence, seen in figurines and ceramics, was present in some Middle Formative sites, indicating cultural exchange. This period also saw the diffusion of a distinctive hard, white pottery and solid figurines with large eyes, marking a horizon that helped archaeologists link different cultures across Mesoamerica. Agriculture, primarily corn farming supplemented by hunting, formed the basis of subsistence.21
