Early history lands The
Hohokam people occupied the Phoenix area for 2,000 years. They created roughly of irrigation canals, making the desert land arable, and paths of these canals were used for the
Arizona Canal,
Central Arizona Project Canal, and the
Hayden-Rhodes Aqueduct. They also carried out extensive trade with the nearby
Ancestral Puebloans,
Mogollon, and
Sinagua, as well as with the more distant
Mesoamerican civilizations. It is believed periods of drought and severe floods between 1300 and 1450 led to the Hohokam civilization's abandonment of the area. After the departure of the Hohokam, groups of
Akimel O'odham (commonly known as Pima),
Tohono O'odham, and
Maricopa tribes began to use the area, as well as segments of the
Yavapai and Apache. The O'odham were offshoots of the
Sobaipuri tribe, who in turn were thought to be the descendants of the Hohokam. The Akimel O'odham were the major group in the area. They lived in small villages with well-defined irrigation systems that spread over the Gila River Valley, from Florence in the east to the Estrellas in the west. Their crops included corn, beans, and squash for food as well as cotton and tobacco. They banded with the Maricopa for protection against incursions by the Yuma and Apache tribes. The Maricopa are part of the larger Yuma people; however, they migrated east from the lower Colorado and Gila Rivers in the early 1800s, when they began to be enemies with other Yuma tribes, settling among the existing communities of the Akimel O'odham. The Tohono O'odham also lived in the region, but largely to the south and all the way to the Mexican border. The O'odham lived in small settlements as seasonal farmers who took advantage of the rains, rather than the large-scale irrigation of the Akimel. They grew crops such as sweet corn, tapary beans, squash, lentils, sugar cane, and melons, as well as taking advantage of native plants such as saguaro fruits, cholla buds, mesquite tree beans, and mesquite candy (sap from the mesquite tree). They also hunted local game such as deer, rabbit, and
javelina for meat. The
Mexican–American War ended in 1848, Mexico ceded its northern zone to the United States, and the region's residents became U.S. citizens. The Phoenix area became part of the
New Mexico Territory. In 1863, the mining town of
Wickenburg was the first to be established in Maricopa County, to the northwest of Phoenix. Maricopa County had not been incorporated; the land was within
Yavapai County, which included the major town of Prescott to the north of Wickenburg. The Army created
Fort McDowell on the
Verde River in 1865 to forestall Indian uprisings. The fort established a camp on the south side of the Salt River by 1866, which was the first settlement in the valley after the decline of the Hohokam. Other nearby settlements later merged to become the city of
Tempe.
Founding and incorporation The history of Phoenix begins with
Jack Swilling, a Confederate veteran of the Civil War who prospected in the nearby mining town of
Wickenburg in the newly formed
Arizona Territory. As he traveled through the
Salt River Valley in 1867, he saw a potential for farming to supply Wickenburg with food. He also noted the eroded mounds of dirt that indicated previous canals dug by native peoples who had long since left the area. He formed the Swilling Irrigation and Canal Company that year, dug a large canal that drew in river water, and erected several crop fields in a location that is now within the eastern portion of central Phoenix near its airport. Other settlers soon began to arrive, appreciating the area's fertile soil and lack of frost, and the farmhouse Swilling constructed became a frequently visited location in the valley.
Lord Darrell Duppa was one of the original settlers in Swilling's party, and he suggested the name "Phoenix", as it described a city born from the ruins of a former civilization. By 1881, Phoenix's continued growth made the board of trustees obsolete. The Territorial Legislature passed the Phoenix Charter Bill, incorporating Phoenix and providing a mayor-council government; Governor
John C. Fremont signed the bill on February 25, 1881, officially incorporating Phoenix as a city with a population of around 2,500. The city offices moved into the new City Hall at Washington and Central in 1888. The arrival of the
Santa Fe, Prescott and Phoenix Railway in 1895 connected Phoenix to Prescott, Flagstaff, and other communities in the northern part of the territory. The increased access to commerce expedited the city's economic rise. The
Phoenix Union High School was established in 1895 with an enrollment of 90. The
National Reclamation Act was signed by President
Theodore Roosevelt in 1902, which allowed dams to be built on waterways in the west for reclamation purposes. The first dam constructed under the act,
Salt River Dam#1, began in 1903. It supplied both water and electricity, becoming the first multi-purpose dam, and Roosevelt attended the official dedication on May 18, 1911. At the time, it was the largest masonry dam in the world, forming
a lake in the mountains east of Phoenix. The dam would be renamed after Teddy Roosevelt in 1917, and the lake would follow suit in 1959. On February 14, 1912, Phoenix became a state capital, as Arizona was admitted to the Union as the 48th state under President
William Howard Taft. This occurred just six months after Taft had vetoed a joint congressional resolution granting statehood to Arizona, due to his disapproval of the state constitution's position on the recall of judges. In 1913, Phoenix's move from a mayor-council system to
council-manager made it one of the first cities in the United States with this form of city government. After statehood, Phoenix's growth started to accelerate; eight years later, its population reached 29,053. In 1920, Phoenix would see its first skyscraper, the
Heard Building; it was the tallest building in the state until the completion of the
Luhrs Building in 1924. On March 4, 1930, former U.S. President
Calvin Coolidge dedicated a dam on the Gila River named in his honor. However, the state had just been through a long drought, and the reservoir which was supposed to be behind the dam was virtually dry. The humorist
Will Rogers, who was on hand as a guest speaker joked, "If that was my lake, I'd mow it." Phoenix's population had nearly doubled during the 1920s and by 1930 stood at 48,118. During World War II, Phoenix's economy shifted to that of a distribution center, transforming into an "embryonic industrial city" with the mass production of military supplies.
Post-World War II explosive growth A town that had just over 65,000 residents in 1940 became America's fifth most populous city by 2020, with a population of nearly 1.6 million, and millions more in nearby suburbs. After the war, many of the men who had undergone their training in Arizona returned with their new families. Learning of this large untapped labor pool enticed many large industries to move their operations to the area. By 1950, over 105,000 people resided in the city and thousands more in surrounding communities. Like many emerging American cities at the time, Phoenix's spectacular growth did not occur evenly. It largely took place on the city's north side, a region that was nearly all Caucasian. In 1962, one local activist testified at a
US Commission on Civil Rights of hearing that of 31,000 homes that had recently sprung up in this neighborhood, not a single one had been sold to an African-American. Phoenix's African-American and Mexican-American communities remained largely sequestered on the south side of town. The color lines were so rigid that no one north of
Van Buren Street would rent to the African-American baseball star
Willie Mays, in town for spring training in the 1960s. In 1964, a reporter from
The New Republic wrote of segregation in these terms: "Apartheid is complete. The two cities look at each other across a golf course."
1960s to present in the background The continued rapid population growth led more businesses to the valley to take advantage of the labor pool, and manufacturing, particularly in the electronics sector, continued to grow. The convention and tourism industries saw rapid expansion during the 1960s, with tourism becoming the third largest industry by the end of the decade. In 1965, the
Phoenix Corporate Center opened; at the time it was the tallest building in Arizona, topping off at 341 feet. The 1960s saw many other buildings constructed as the city expanded rapidly, including the Rosenzweig Center (1964), today called
Phoenix City Square, the landmark
Phoenix Financial Center (1964), as well as many of Phoenix's residential high-rises. In 1965 the
Arizona Veterans Memorial Coliseum opened at the
Arizona State Fairgrounds, west of downtown. When Phoenix was awarded an
NBA franchise in 1968, which would be called the
Phoenix Suns, they played their home games at the Coliseum until 1992, after which they moved to
America West Arena. In 1968, President
Lyndon B. Johnson approved the
Central Arizona Project, assuring future water supplies for Phoenix, Tucson, and the agricultural corridor between them. The following year,
Pope Paul VI created the
Diocese of Phoenix on December 2, by splitting the Archdiocese of Tucson, with
Edward A. McCarthy as the first Bishop. In the 1970s, the downtown area experienced a resurgence, with a level of construction activity not seen again until the urban real estate boom of the 2000s. By the end of the decade, Phoenix adopted the Phoenix Concept 2000 plan which split the city into urban villages, each with its own village core where greater height and density was permitted, further shaping the free-market development culture. The nine original villages have expanded to 15 over the years (see
Cityscape below). This officially turned Phoenix into a city of many nodes, which would later be connected by freeways. The
Phoenix Symphony Hall opened in 1972; other major structures which saw construction downtown during this decade were the
First National Bank Plaza, the
Valley Center (the tallest building in Arizona), and the
Arizona Bank building. On September 25, 1981, Phoenix resident
Sandra Day O'Connor broke the gender barrier on the
U.S. Supreme Court, when she was sworn in as the first female justice. In 1985, the
Palo Verde Nuclear Generating Station, the nation's largest nuclear power plant, began electrical production.
Pope John Paul II and
Mother Teresa both visited the Valley in 1987. There was an influx of refugees due to low-cost housing in the
Sunnyslope area in the 1990s, resulting in 43 different languages being spoken in local schools by 2000. The new 20-story
City Hall opened in 1992. Phoenix maintained a growth streak in the early 2000s, growing by 24.2% before 2007. In 2008, Squaw Peak, the city's second tallest mountain, was renamed
Piestewa Peak after Army Specialist
Lori Ann Piestewa, an Arizonan and the first
Native American woman to die in combat while serving in the U.S. military, as well as being the first American female casualty of the
2003 Iraq War. 2008 also saw Phoenix as one of the cities hardest hit by the
subprime mortgage crisis, and by early 2009 the median home price was $150,000, down from its $262,000 peak in 2007. Violent rates in Phoenix have been falling since 2023, and once troubled, decaying neighborhoods such as
South Mountain,
Alhambra, and
Maryvale have recovered and stabilized. On June 1, 2023, the State of Arizona announced the decision to halt new housing development in the Phoenix metropolitan area that relies solely on
groundwater due to a predicted water shortfall. ==Geography==
