(Via Visit Tucson)

Located in the Southwest United States, in Southern Arizona, Tucson is one of the oldest continually inhabited areas in North America. Hohokam Indians lived and farmed here for 4,000 years before Spanish missionaries and soldiers arrived in the late 1600s. In the 1700s, these “newcomers” established the Presidio San Agustín del Tucson and theMission San Xavier del Bac—the two most  iconic and historic structures in the region. “The Old Pueblo,” as the adobe-walled Tucson Presidio became known, is Tucson’s nickname to this day.

Tucson officially was founded on August 20, 1775—an event celebrated annually at Tucson’s birthday party, La Fiesta de San Agustín. Though once part of Mexico, Tucson officially became part of the United States in 1854. Soon after, cattle ranchers, settlers, miners, and Apache Indians began to clash, thus beginning the Wild West era of 1860-1880. With the Southern Pacific Railroad’s arrival in 1880, Tucson’s multicultural roots grew as new residents adopted customs of the Tohono O’odham Indians and Mexicans living here. In 1877, the city was incorporated, making Tucson the oldest incorporated city in Arizona.

Tucson is now the second-largest city in Arizona after the state capital Phoenix; it is also the county seat of Pima County, which includes the towns of Marana, Oro Valley, Catalina, South Tucson, Sahuarita, Vail, and Green Valley. Pima County, including Metropolitan Tucson’s population is more than 1 million; this includes roughly 50,000 students and employees at the University of Arizona, the first university in Arizona, founded in 1885.
