Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.
Southern Arizona is known for its desert climate, with very hot summers and mild winters. Northern Arizona features forests of pine, Douglas fir, and spruce trees; the Colorado Plateau; mountain ranges (such as the San Francisco Mountains); as well as large, deep canyons, with much more moderate summer temperatures and significant winter snowfalls. There are ski resorts in the areas of Flagstaff, Sunrise, and Tucson. In addition to the internationally known Grand Canyon National Park, which is one of the world’s seven natural wonders, there are several national forests, national parks, and national monuments.

Brigham Young, patriarchal leader of the Church of Jesus Christ of Latter-day Saints in Salt Lake City in Utah, sent Mormons to Arizona in the mid- to late 19th century. They founded Mesa, Snowflake, Heber, Safford, and other towns. They also settled in the Phoenix Valley (or «Valley of the Sun»), Tempe, Prescott, and other areas. The Mormons settled what became northern Arizona and northern New Mexico. At the time these areas were in a part of the former New Mexico Territory.

Three ships named USS Arizona have been christened in honor of the state, although only USS Arizona (BB-39) was so named after statehood was achieved.
The Mogollon Rim (/ ˌmoʊ gəˈyoʊn /), a 1,998-foot (609 m) escarpment, cuts across the state’s central section and marks the southwestern edge of the Colorado Plateau. In 2002, this was an area of the Rodeo–Chediski Fire, the worst fire in state history until 2011.
Located in northern Arizona, the Grand Canyon is a colorful, deep, steep-sided gorge, carved by the Colorado River. The canyon is one of the Seven Natural Wonders of the World and is largely contained in the Grand Canyon National Park – one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of designating the Grand Canyon area as a National Park, often visiting to hunt mountain lion and enjoy the scenery. The canyon was created by the Colorado River cutting a channel over millions of years, and is about 277 miles (446 km) long, ranges in width from 4 to 18 miles (6 to 29 km) and attains a depth of more than 1 mile (1.6 km). Nearly two billion years of the Earth’s history have been exposed as the Colorado River and its tributaries cut through layer after layer of sediment as the Colorado Plateau uplifted.
Arizona is one of two U.S. states, along with Hawaii, that does not observe Daylight Saving Time, though the large Navajo Nation in the state’s northeastern region does.
Due to the primarily dry climate, large diurnal temperature variations occur in less-developed areas of the desert above 2,500 ft (760 m). The swings can be as large as 83 °F (46 °C) in the summer months. In the state’s urban centers, the effects of local warming result in much higher measured night-time lows than in the recent past.
Cities and towns
Tucson, with a metro population of just over one million, is the state’s second-largest city. Located in Pima County, approximately 110 miles (180 km) southeast of Phoenix, it was incorporated in 1877, making it the oldest incorporated city in Arizona. It is home to the University of Arizona. Major incorporated suburbs of Tucson include Oro Valley and Marana northwest of the city, Sahuarita south of the city, and South Tucson in an enclave south of downtown. It has an average July temperature of 100 °F (38 °C) and winter temperatures averaging 65 °F (18 °C). Saguaro National Park, just west of the city in the Tucson Mountains, is the site of the world’s largest collection of Saguaro cacti.
The Prescott metropolitan area includes the cities of Prescott, Cottonwood, Camp Verde and many other towns in the 8,123 square miles (21,000 km2) of Yavapai County area. With 212,635 residents, this cluster of towns is the state’s third largest metropolitan area. The city of Prescott (population 41,528) lies approximately 100 miles (160 km) northwest of the Phoenix metropolitan area. Situated in pine tree forests at an elevation of about 5,500 feet (1,700 m), Prescott enjoys a much cooler climate than Phoenix, with average summer highs around 88 °F (31 °C) and winter temperatures averaging 50 °F (10 °C).
Yuma is the center of the fourth-largest metropolitan area in Arizona. Located in Yuma County, it is near the borders of California and Mexico. It is one of the hottest cities in the United States, with an average July high of 107 °F (42 °C). (The same month’s average in Death Valley is 115 °F (46 °C).) The city features sunny days about 90% of the year. The Yuma Metropolitan Statistical Area has a population of 160,000. Yuma attracts many winter visitors from all over the United States.
Flagstaff, in Coconino County, is the largest city in northern Arizona, and is at an elevation of nearly 7,000 feet (2,100 m). With its large Ponderosa pine forests, snowy winter weather and picturesque mountains, it is a stark contrast to the desert regions typically associated with Arizona. It is sited at the base of the San Francisco Peaks, the highest mountain range in the state of Arizona, which contains Humphreys Peak, the highest point in Arizona at 12,633 feet (3,851 m). Flagstaff has a strong tourism sector, due to its proximity to numerous tourist attractions including: Grand Canyon National Park, Sedona, and Oak Creek Canyon. Historic U.S. Route 66 is the main east–west street in the town. The Flagstaff metropolitan area is home to 134,421 residents and the main campus of Northern Arizona University.
Metropolitan Phoenix (4.7 million) and Tucson (1.0 million) are home to about five-sixths of Arizona’s people (as of the 2010 census). Metro Phoenix alone accounts for two-thirds of the state’s population.
Race and ethnicity
The state rate on transient lodging (hotel/motel) is 7.27%. The state of Arizona does not levy a state tax on food for home consumption or on drugs prescribed by a licensed physician or dentist. However, some cities in Arizona do levy a tax on food for home consumption.
Public transportation, Amtrak, and intercity bus
The Phoenix and Tucson metropolitan areas are served by public bus transit systems. Yuma and Flagstaff also have public bus systems. Greyhound Lines serves Phoenix, Tucson, Flagstaff, Yuma, and several smaller communities statewide.
Law and government
The House of Representatives and Senate buildings were dedicated in 1960, and an Executive Office Building was dedicated in 1974 (the ninth floor of this building is where the Office of the Governor is located). The original Capitol building was converted into a museum.
The Capitol complex is fronted and highlighted by the richly landscaped Wesley Bolin Memorial Plaza, named after Wesley Bolin, a governor who died in office in the 1970s. The site also includes many monuments and memorials, including the anchor and signal mast from the USS Arizona (one of the U.S. Navy ships sunk in Pearl Harbor) and a granite version of the Ten Commandments.
State legislative branch
Arizona state senators and representatives are elected for two-year terms and are limited to four consecutive terms in a chamber, though there is no limit on the total number of terms. When a lawmaker is term-limited from office, it is common for him or her to run for election in the other chamber.
State executive branch
Arizona’s executive branch is headed by a governor, who is elected to a four-year term. The governor may serve any number of terms, though no more than two in a row. Arizona is one of the few states that has no governor’s mansion. During their term, the governors reside within their private residence, with executive offices housed in the executive tower at the state capitol. The governor of Arizona is Katie Hobbs (D).
Arizona is one of five states that do not have a lieutenant governor. The elected secretary of state is first in line to succeed the governor in the event of death, disability, resignation, or removal from office. If appointed, the Secretary of State is not eligible and the next governor is selected from the next eligible official in the line of succession, including the attorney general, state treasurer, and superintendent of public instruction. Since 1977, four secretaries of state and one attorney general have succeeded to Arizona’s governorship.
State judicial branch
The Arizona Court of Appeals, subdivided into two divisions, is the intermediate court in the state. Division One is based in Phoenix, consists of nineteen judges, and has jurisdiction in the Western and Northern regions of the state, along with the greater Phoenix area. Division Two is based in Tucson, consists of nine judges, and has jurisdiction over the Southern regions of the state, including the Tucson area. Judges are selected in a method similar to the one used for state supreme court justices.
Each county of Arizona has a superior court, the size and organization of which are varied and generally depend on the size of the particular county.
Arizona is divided into 15 counties, ranging in size from 1,238 square miles (3,210 km2) to 18,661 square miles (48,330 km2).
Arizona’s two United States Senators are Kyrsten Sinema (I) and Mark Kelly (D).
Arizona’s United States Representatives are David Schweikert (R-1), Eli Crane (R-2), Ruben Gallego (D-3), Greg Stanton (D-4), Andy Biggs (R-5), Juan Ciscomani (R-6), Raul Grijalva (D-7), Debbie Lesko (R-8), and Paul Gosar (R-9). Arizona gained a ninth seat in the House of Representatives due to redistricting based on the 2010 United States census.
Party registration by Arizona county (January 2023)
From statehood through the late 1940s, Arizona was primarily dominated by the Democratic Party. During this time, the Democratic candidate for the presidency carried the state each election, the only exceptions being the elections of 1920, 1924 and 1928 – all three were national Republican landslides.
Arizona voted Republican in every presidential election from 1952 to 1992, with Richard Nixon and Ronald Reagan winning the state by particularly large margins. During this forty-year span, it was the only state not to be carried by a Democrat at least once.
Since the mid 20th century, the Republican Party has also dominated Arizona politics in general. The fast-growing Phoenix and Tucson suburbs became reliably Republican areas from the 1950s onward. During this time, many «Pinto Democrats», or conservative Democrats from rural areas, became increasingly willing to support Republicans at the state and national level. While the state normally supports Republicans at the federal level, Democrats are often competitive in statewide elections. Two of the last six governors have been Democrats.
On March 4, 2008, Senator John McCain effectively clinched the Republican nomination for 2008, becoming the first major party presidential nominee from the state since Barry Goldwater in 1964.
Arizona politics are dominated by a longstanding rivalry between its two largest counties, Maricopa and Pima – home to Phoenix and Tucson, respectively. The two counties have almost 75 percent of the state’s population and cast almost 80 percent of the state’s vote. They also elect a substantial majority of the state legislature.
Maricopa County is home to almost 60 percent of the state’s population, and most of the state’s elected officials live there. Before Joe Biden won Maricopa County in 2020, it had voted Republican in every presidential election since 1952. This includes the 1964 run of native son Barry Goldwater; he would not have carried his home state without his 20,000-vote margin in Maricopa County. Similarly, McCain won Arizona by eight percentage points in 2008, aided by his 130,000-vote margin in Maricopa County.
In contrast, Pima County, home to Tucson, and most of southern Arizona have historically voted more Democratic. While Tucson’s suburbs lean Republican, they hold to a somewhat more moderate brand of Republicanism than is common in the Phoenix area.

Arizona is a recognized center of Native American art, with a number of galleries showcasing historical and contemporary works. The Heard Museum, also in Phoenix, is a major repository of Native American art. Some of the signature exhibits include a full Navajo hogan, the Mareen Allen Nichols Collection containing 260 pieces of contemporary jewelry, the Barry Goldwater Collection of 437 historic Hopi kachina dolls, and an exhibit on the 19th-century boarding school experiences of Native Americans. The Heard Museum has about 250,000 visitors a year.

Several major Hollywood films, such as Billy Jack, U Turn, Waiting to Exhale, Just One of the Guys, Can’t Buy Me Love, Bill & Ted’s Excellent Adventure, The Scorpion King, The Banger Sisters, Used Cars, and Raising Arizona have been made there (as have many Westerns). The 1993 science fiction movie Fire in the Sky, based on a reported alien abduction in the town of Snowflake, was set in Snowflake. It was filmed in the Oregon towns of Oakland, Roseburg, and Sutherlin.
The 1974 film Alice Doesn’t Live Here Anymore, for which Ellen Burstyn won the Academy Award for Best Actress, and also starring Kris Kristofferson, was set in Tucson. The climax of the 1977 Clint Eastwood film The Gauntlet takes place in downtown Phoenix. The final segments of the 1984 film Starman take place at Meteor Crater outside Winslow. The Jeff Foxworthy comedy documentary movie Blue Collar Comedy Tour was filmed almost entirely at the Dodge Theatre. Some of Alfred Hitchcock’s classic film Psycho was shot in Phoenix, the ostensible home town of the main character.
Some of the television shows filmed or set in Arizona include The New Dick Van Dyke Show, Medium, Alice, The First 48, Insomniac with Dave Attell, Cops, and America’s Most Wanted. The TV sitcom Alice, which was based on the movie was set in Phoenix. Twilight had passages set in Phoenix at the beginning and the end of the film.
Arizona is prominently featured in the lyrics of many Country and Western songs, such as Jamie O’Neal’s hit ballad «There Is No Arizona». George Strait’s «Oceanfront Property» uses «ocean front property in Arizona» as a metaphor for a sucker proposition. The line «see you down in Arizona Bay» is used in a Tool song in reference to the possibility (expressed as a hope by comedian Bill Hicks) that Southern California will one day fall into the ocean. Glen Campbell, a notable resident, popularized the song «By The Time I Get To Phoenix».
Arizona’s budding music scene is helped by emerging bands, as well as some well-known artists. The Gin Blossoms, Chronic Future, Roger Clyne and the Peacemakers, Jimmy Eat World, Caroline’s Spine, and others began their careers in Arizona. Also, a number of punk and rock bands got their start in Arizona, including JFA, The Feederz, Sun City Girls, The Meat Puppets, The Maine, The Summer Set, and more recently Authority Zero and Digital Summer.
Arizona also has many singers and other musicians. Singer, songwriter and guitarist Michelle Branch is from Sedona. Chester Bennington, the former lead vocalist of Linkin Park, and mash-up artist DJ Z-Trip are both from Phoenix. One of Arizona’s better known musicians is shock rocker Alice Cooper, who helped define the genre. Maynard James Keenan, the lead singer of the bands Tool, A Perfect Circle, and Puscifer, calls the town of Cornville home.
Other notable singers include country singers Dierks Bentley and Marty Robbins, folk singer Katie Lee, Fleetwood Mac’s Stevie Nicks, CeCe Peniston, Rex Allen, 2007 American Idol winner Jordin Sparks, and Linda Ronstadt.
Arizona is also known for its heavy metal scene, which is centered in and around Phoenix. In the early to mid-1990s, it included bands such as Job for a Cowboy, Knights of the Abyss, Greeley Estates, Eyes Set To Kill, blessthefall, The Word Alive, The Dead Rabbitts, and Abigail Williams. The band Soulfly calls Phoenix home and Megadeth lived in Phoenix for about a decade. Beginning in and around 2009, Phoenix began to host a burgeoning desert rock and sludge metal underground, (ala’ Kyuss in 1990s California) led by bands like Wolves of Winter, Asimov, and Dead Canyon.
Arizona also hosts several college football bowl games. The Fiesta Bowl, originally held at Sun Devil Stadium, is now held at State Farm Stadium in Glendale. The Fiesta Bowl is part of the new College Football Playoff (CFP). University of Phoenix Stadium was also home to the 2007 and 2011 BCS National Championship Games.
