The Sinagua people were an ancient Native American culture that inhabited the northern regions of present-day Arizona from around 600 to 1400 CE. They are known for their unique adobe and stone dwellings, often built into cliffs and canyons, which provided protection from the elements and enemies. The Sinagua primarily engaged in agriculture, cultivating crops like corn, beans, and squash, and they also hunted and gathered local resources. The Sinagua culture is closely associated with the Hohokam and Ancestral Puebloans, sharing some similarities in pottery and architectural styles. By the late 14th century, many Sinagua communities began to decline, likely due to factors such as drought, resource depletion, and social changes, leading to their eventual migration to other areas.
