A Brief History of Tucson
The history of life in the Tucson Valley begins ca. 10,000 B.C. with the migrations of Paleoindian and Archaic hunters and gatherers. Whether or not there was continuous habitation is unclear, though evidence of agricultural settlements along the Santa Cruz River have been found dating from ca. 1000 B.C.
Between A.D. 200 and 1450, the Hohokam culture thrives. The Pima and Tohono O'odham are the descendents of that advanced civilization, and have inhabited the region since the Hohokam decline.
