The name "Tucson" comes from the O'odham word "Tüscon." This word is a stative verb. In the O'odham language, it means "to be black" or "to be dark." It can also refer to a base or foundation. Many people translate the name as "the base of the hill is black." This likely refers to Sentinel Peak, a hill covered in basalt.

The city has several nicknames. Some call it the "Old Pueblo." Others call it "Optics Valley." This name refers to the city's global reputation for optical science and telescopes.

Human history in this region began long before the city was founded. Paleo-Indians likely visited the area about 12,000 years ago. Archaeological sites near the Santa Cruz River show a village existed in 2100 BC. During the Early Agricultural Period, people farmed the river's floodplain. They grew corn and beans using irrigation canals. They also hunted and gathered wild plants. The Hohokam people lived here from AD 600 to AD 1450. They are famous for their red-on-brown pottery. They also built very large irrigation canal systems.

European influence arrived through Spanish explorers and missionaries. Eusebio Francisco Kino visited the Santa Cruz River valley in 1692. He founded the Mission San Xavier del Bac in 1700. Later, Hugo O'Conor authorized a military fort in 1775. This fort was called Presidio San Agustín del Tucsón. The modern Pima County Courthouse sits near this original site. The area's political control changed many times. It was part of the Spanish Empire and later Mexico. In 1853, the United States acquired the land through the Gadsden Purchase. This treaty brought Tucson into the United States. The city served as the capital of the Arizona Territory from 1867 to 1877.

The late 1800s were a period of both growth and conflict. The city was the largest in Arizona during the territorial period. However, Phoenix eventually surpassed it in population by 1920. The frontier was often violent due to Apache attacks on settlers. The U.S. Army established Fort Lowell to provide protection. The era also saw famous gunfighters and stagecoach robberies. One notable figure was William Whitney Brazelton, a masked road agent. Even during the Civil War, Tucson saw military engagements. The Battle of Picacho Pass occurred in April 1862. Union forces eventually captured the city during that conflict.

Tucson's environment has shaped how people live there. The city is known for its clean, dry air. In the early 20th century, many veterans came here for respiratory therapy. They sought treatment for issues caused by gases used in World War I. The high altitude and dry conditions were also used to treat tuberculosis.

The University of Arizona was founded in 1885. It began as a land-grant college on ranchland. Today, the university is a central part of the city's identity.
