History of Pima County
Pima County, one of the four original counties in Arizona, was created by the 1st Arizona Territorial Legislature with land acquired through the Gadsden Purchase from Mexico in 1853. The original county consisted of all of Arizona Territory east of longitude 113° 20' and south of the Gila River. Soon thereafter, the counties of Cochise, Graham and Santa Cruz were carved from the original Pima County.
