There has been much research, writing, and speculation on the Mesoamerican roots of prehistoric southwestern culture, and while scholars all agree on the importance of the northern spread of influences from the more ancient civilizations of southern Mexico, they have not as yet traced in detail what development came from what region, nor at what time. Although there are many gap of knowledge and differences of opinion, there is little disagreement among scientists that the Hohokam, the principal prehistoric inhabitants of southern Arizona, played an active role in what has been called "the Mexican connection."

By the middle of the sixteenth century, the Spanish and Portuguese -- no longer faced with effective resistance from the native populations -- had established colonial control over all of South America and much of North America. In the parts of North America that would eventually become the United States, the European presence was for a time less powerful. The Spanish established an important northern outpost in what is now New Mexico, a society in which Europeans and Indians lived together intimately, if unequally. On the whole, however, the North American Indians remained largely undisturbed by Europeans until English, French and Dutch migrations began in the early seventeenth century. Brinkley, p 26
