The history of Arizona encompasses the Paleo-Indian, Archaic, Post-Archaic, Spanish, Mexican, and American periods. About 10,000 to 12,000 years ago, Paleo-Indians settled in what is now Arizona. A few thousand years ago, the Ancestral Puebloan, the Hohokam, the Mogollon and the Sinagua cultures inhabited the state. However, all of these civilizations mysteriously disappeared from the region in the 15th and 16th centuries. Today, countless ancient ruins can be found in Arizona. Arizona was part of the state of Sonora, Mexico from 1822, but the settled population was small. In 1848, under the terms of the Mexican Cession the United States took possession of Arizona north of the Gila River. It became part of the Territory of New Mexico. In 1854 the United States purchased the part of the Arizona south of the Gila River, which later allowed a rail connection from Yuma to El Paso.
In 1863, Arizona was split off from the Territory of New Mexico to form the Arizona Territory. The remoteness of the region ended with the arrival of railroads in 1880.Richard J. Orsi, Sunset limited: the Southern Pacific Railroad and the development of the American West, 1850-1930 (Univ of California Press, 2005) pp.20-22. Arizona became a state in 1912. It was primarily rural with an economy based on cattle, cotton, citrus, and copper. Dramatic growth came after 1945, as retirees and young families who appreciated the warm weather and low costs emigrated from the Northeast and Midwest. By the 1990s many new arrivals came, increasing the population dramatically, particularly in the metropolitan Phoenix area.
Paleo-Indian period
Paleo-Indians settled what is now Arizona around 10,000 to 12,000 years ago. According to most archaeologists, the Paleo-Indians initially followed herds of big game—megafauna such as mammoths, mastodons, and bison—into North America. The traveling groups also collected and utilized a wide variety of smaller game animals, fish, and a wide variety of plants. These people were likely characterized by highly mobile bands of approximately 20 or 50 members of an extended family, moving from place to place as resources were depleted and additional supplies needed. Paleoindian groups were efficient hunters and created and carried a variety of tools, some highly specialized, for hunting, butchering and hide processing. These paleolithic people utilized the environment that they lived in near water sources, including rivers, swamps and marshes, which had an abundance of fish, and drew birds and game animals. Big game, including bison, mammoths and ground sloths, also were attracted to these water sources. At the latest by 9500 BCE, bands of hunters wandered as far south as Arizona, where they found a desert grassland and hunted mule deer, antelope and other small mammals.
As populations of larger game began to diminish, possibly as a result of intense hunting and rapid environmental changes, Late Paleoindian groups would come to rely more on other facets of their subsistence pattern, including increased hunting of bison, mule deer and antelope. Nets and the atlatl to hunt water fowl, ducks, small animals and antelope. Hunting was especially important in winter and spring months when plant foods were scarce.

Archaic period
The Archaic time frame is defined culturally as a transition from a hunting/gathering lifestyle to one involving agriculture and permanent, if only seasonally occupied, settlements. In the Southwest, the Archaic is generally dated from 8000 years ago to approximately 1800 to 2000 years ago.Cordell, Linda S. (1994). Ancient Pueblo Peoples. St. Remy Press and Smithsonian Institution. p. 34. . During this time the people of the southwest developed a variety of subsistence strategies, all using their own specific techniques. The nutritive value of weed and grass seeds was discovered and flat rocks were used to grind flour to produce gruels and breads. This use of grinding slabs in about 7500 BCE marks the beginning of the Archaic tradition. Small bands of people traveled throughout the area, gathering plants such as cactus fruits, mesquite beans, acorns, and pine nuts and annually establishing camps at collection points.
Late in the Archaic Period, corn, probably introduced into the region from central Mexico, was planted near camps with permanent water access. Distinct types of corn have been identified in the more well-watered highlands and the desert areas, which may imply local mutation or successive introduction of differing species. Emerging domesticated crops also included beans and squash.
About 3,500 years ago, climate change led to changing patterns in water sources, leading to a dramatically decreased population. However, family-based groups took shelter in south facing caves and rock overhangs within canyon walls. Occasionally, these people lived in small semisedentary hamlets in open areas. Evidence of significant occupation has been found in the northern part of Arizona.
Archaic cultural traditions include: Archaic–Early Basketmaker (7000–1500 BCE) San Dieguito–Pinto (6500 BCE – 200 CE) Oshara (5500 BCE – 600 CE) Cochise (before 5000 BCE – 200 CE) Chihuahua (6000 BCE –250 CE)
Post-Archaic period
In the Post-Archaic period, the Ancestral Puebloan, the Hohokam, the Mogollon and Sinagua cultures inhabited what is now Arizona. These cultures built structures made out of stone. Some of the structures that these cultures built are called pueblos. Pueblos are monumental structures that housed dozens to thousands of people. In some Ancestral Puebloan towns and villages, Hohokam towns and villages, Mogollon towns and villages, and Sinagua towns and villages, the pueblo housed the entire town. Surrounding the pueblos were often farms where farmers would plant and harvest crops to feed the community. Sometimes, pueblos and other buildings were built in caves in cliffs.
Ancestral Puebloans The Ancestral Puebloans were an ancient Pre-Columbian Native American civilization that spanned the present-day Four Corners region of the United States, comprising southeastern Utah, northeastern Arizona, northwestern New Mexico, and southwestern Colorado."Ancestral Pueblo culture." Encyclopædia Britannica. Retrieved 4 June 2012. The Ancestral Puebloans are believed to have developed, at least in part, from the Oshara tradition, who developed from the Picosa culture.
They lived in a range of structures that included small family pit houses, larger structures to house clans, grand pueblos, and cliff-sited dwellings for defense. The Ancestral Puebloans possessed a complex network that stretched across the Colorado Plateau linking hundreds of communities and population centers. They held a distinct knowledge of celestial sciences that found form in their architecture. The kiva, a congregational space that was used chiefly for ceremonial purposes, was an integral part of this ancient people's community structure. Some of their most impressive structures were built in what is now Arizona.
Hohokam
Hohokam () was a Pre-Columbian culture in the North American Southwest in what is now part of Arizona, United States, and Sonora, Mexico. Hohokam practiced a specific culture, sometimes referred to as Hohokam culture, which has been distinguished by archeologists. People who practiced the culture can be called Hohokam as well, but more often, they are distinguished as Hohokam people to avoid confusion.
Most archaeologists agree that the Hohokam culture existed between c. 300 and c. 1450 CE, but cultural precursors may have been in the area as early as 300 BC. Whether Hohokam culture was unified politically remains under controversy. Hohokam culture may have just given unrelated neighboring communities common ground to help them to work together to survive their harsh desert environment.
Mogollon The Mogollon culture () was an ancient Pre-Columbian culture of Native American peoples from Southern New Mexico and Arizona, Northern Sonora and Chihuahua, and Western Texas. The northern part of this region is Oasisamerica, while the southern span of the Mogollon culture is known as Aridoamerica.
The Mogollon culture was one of the major prehistoric Southwestern cultural divisions of the Southwestern United States and Northern Mexico. The culture flourished from , to c. 1450 CE or 1540 CE, when the Spanish arrived.
Sinagua
The Sinagua culture was a Pre-Columbian culture that occupied a large area in central Arizona from the Little Colorado River, near Flagstaff, to the Verde River, near Sedona, including the Verde Valley, area around San Francisco Mountain, and significant portions of the Mogollon Rim country, between approximately 500 CE and 1425 CE. Besides ceremonial kivas, their pueblos had large "community rooms" and some featured ballcourts and walled courtyards, similar to those of the Hohokam culture. Since fully developed Sinagua sites emerged in central Arizona around 500 CE, it is believed they migrated from east-central Arizona, possibly emerging from the Mogollon culture.
Spanish and Mexican Arizona
The history of Arizona as recorded by Europeans began in 1539 with the first documented exploration of the area by Marcos de Niza, early work expanded the following year when Francisco Vásquez de Coronado entered the area as well.
The Spanish established a few missions in southern Arizona in the 1680s by Father Eusebio Francisco Kino along the Santa Cruz River, in what was then the Pimería Alta region of Sonora. The Spanish also established presidios in Tubac and Tucson in 1752 and 1775. The area north of the Gila River was governed by the Province of Las California under the Spanish until 1804, when the Californian portion of Arizona became part of Alta California under the Spanish and Mexican governments.
American Arizona
In the Mexican–American War, the garrison commander avoided conflict with Lieutenant Colonel Cooke and the Mormon Battalion, withdrawing while the Americans marched through the town on their way to California. In the Treaty of Guadalupe Hidalgo (1848), Mexico ceded to the U.S. the northern 70% of modern-day Arizona above the Sonora border along the Gila River.
During the California Gold Rush, upwards of 50,000 people traveled through on the Southern Emigrant Trail pioneered by Cooke, to reach the gold fields in 1849.C. L. Sonnichsen, Tucson: The Life and Times of an American City (1987) pp. 30–38 The Pima Villages often sold fresh food and provided relief to distressed travelers among this throng and to others in subsequent years.
In 1853, President Franklin Pierce sent James Gadsden to Mexico City to negotiate with Santa Anna, and the United States bought the remaining southern strip area of Arizona and New Mexico in the Gadsden Purchase. A treaty was signed in Mexico in December 1853, and then, with modifications, approved by the US Senate in June 1854, setting the southern boundary of Arizona and of New Mexico.
Before 1846 the Apache Indians expelled most Mexican ranchers. One result was that large herds of wild cattle roamed southeastern Arizona. By 1850, the herds were gone, killed by Apaches, American sportsmen, contract hunting for the towns of Fronteras and Santa Cruz, and roundups to sell to hungry Mexican War soldiers, and forty-niners en route to California.Larry D. Christiansen, "The Extinction of Wild Cattle in Southern Arizona," Journal of Arizona History (1988) 29#1 pp. 89–100.
Civil War
During the Civil War, on March 16, 1861, some residents in southern New Mexico Territory around Mesilla (now in New Mexico) and Tucson invited take-over by the Confederacy. These secessionists hoped that a Confederate Territory of Arizona (CSA) would take control, but in March 1862, Union troops from California recaptured the so-called "Confederate Territory of Arizona" and returned it to the New Mexico Territory.
