The Anasazi, also known as the Ancestral Puebloans, were an ancient Native American civilization that thrived in the southwestern United States, particularly in present-day Arizona, New Mexico, Colorado, and Utah, from around 100 AD to 1300 AD. They are known for their distinctive adobe and stone cliff dwellings, as well as their advanced agricultural practices, including the cultivation of maize, beans, and squash. The Anasazi culture is marked by significant achievements in pottery, weaving, and architecture, but they mysteriously abandoned their settlements around the late 13th century, likely due to factors such as drought and resource depletion. Today, their legacy continues to influence the cultural practices of contemporary Pueblo peoples.
