Tucson was probably first visited by Paleo-Indians, known to have been in southern Arizona by about 12,000 years ago. Recent archaeological excavations near the Santa Cruz River have located a village site dating from 4,000 years ago. The floodplain of the Santa Cruz River was extensively farmed during the Early Agricultural period, circa 1200 BC to AD 150. These people constructed irrigation canals and grew corn, beans, and other crops while gathering wild plants and hunting animals. The Early Ceramic period occupation of Tucson saw the first extensive use of pottery vessels for cooking and storage. The groups designated by archaeologists as the Hohokam stayed in the area from AD 600-1450 and are known for their red-on-brown pottery.

Jesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac about 7 miles (12 km) upstream from the site of the settlement of Tucson in 1700. The Spanish established a presidio (fort) on August 20, 1775 and the town came to be called "Tucson." Tucson became a part of Mexico after Mexico gained independence from Spain in 1821. Following the Gadsden purchase in 1853, Tucson became a part of the US of America, although the US military did not formally take over control of the community until March 1856. From August 1861, until mid-1862, Tucson was the capital of the Confederate Arizona Territory. Until 1863, Tucson and all of Arizona was part of New Mexico Territory. From 1867 to 1879, Tucson was the capital of Arizona Territory. The University of Arizona, located in Tucson, was founded in 1885.

During the territorial and early statehood periods, Tucson was Arizona`s largest city and commercial area, whereas Phoenix was the seat of state government and agriculture. The establishment of Tucson Municipal Airport increased its importance. By the 1920s-30s, Phoenix outgrew Tucson and has continued to enlarge. Tucson has still been growing but at a slower pace. 1909.

As a result, residences consume the vast majority of municipal water. Like golf courses, agricultural lands are turning toward reclaimed water. Mining and other industrial water uses combined accounted for about a 15% of water use in 1997 . Although Tucsonans find lawns and swimming pools less acceptable than their neighbors in Phoenix, massive drawing down of groundwater resources over the last 100 years has occurred, visible as ground subsidence in some residential areas.
