A prehistoric tradition of southern Arizona which began as a sedentary farming culture around 300 BC and existed until 1400/1450 AD. It was a cultural unit within the Cochise subculture and it had large villages, canal irrigation, and pottery-making. The finest craft products were shell jewelry and objects of carved stone. Diagnostic traits include small villages of shallow, oblong pit-houses with no formalized community plan, cremation of the dead, plain grey or brown paddle and anvil smoothed pottery (or sometimes painted red on buff). The tradition is divided into: Pioneer (150-550 AD), Colonial (550-900 AD), Sedentary (900-1100 AD), Classic (1100-1450 AD), and Post-Classic (1450-1700 AD). Between 550-1200 AD, renewed Mexican contacts brought foreign elements to the Hohokam: courts for the ball-game, platform mounds, new types of maize, slab metates, mosaic mirrors, exotic symbolism from Mexican religion, and the use of copper bells. From about 1100, certain groups began to construct pueblos under Anasazi influence. After 1400/1450, the Hohokam territory along the Gila and Salt Rivers seems to have been partially abandoned. Their cultural heirs are the Pima and Papago Indians. Snaketown is an important Hohokam site.
