The Chacoan people were an ancient Native American civilization that thrived in the Chaco Canyon region of present-day New Mexico from around AD 900 to 1150. They are known for their impressive architectural achievements, including large multi-story buildings called great houses, which served as centers for trade, politics, and religion. The Chacoans developed an extensive network of roads connecting various communities, facilitating communication and commerce. Their society was highly organized, with evidence of complex social structures and cultural practices. The Chacoan people engaged in agriculture, growing crops like maize, beans, and squash, which supported their population. The decline of the Chacoan civilization around the late 12th century is believed to be linked to environmental changes and resource depletion.
