History


Early Inhabitants

The Huhugam people migrated to the Gila River Valley around 300 BCE. They constructed over 500 miles of canals and were able to farm and conduct trade along the river. It is estimated that around 50,000-60,000 Huhugam people populated the Gila River Valley at the height of their “Classic Period” (around 1150-1450 CE). The Huhugam are considered the ancestors of the Akimel O’odham or

led a handful of soldiers on this surveying expedition. During the expedition in Graham Country, General Carleton took note of a tactical location offering a wide open view of the Gila Valley where he would later establish Fort Goodwin. In addition, scouts from railroad companies explored the Gila River Valley looking for a potential railroad route across the newly bought land. It wasn't until early 1878 that the first group of Mormon scouts from Northern Arizona entered the Gila Valley with the intent to settle. The Mormon scouts returned to the Gila River Valley for a second time in 1879.


First Pioneers

Joseph K. Rodgers, alongside a small group of Mormon Pioneers, settled  Smithville in 1879 after receiving positive reports from Mormon scouts sent to the area earlier in the same year. The settlers quickly dug irrigation ditches along the banks of the Gila river and planted crops in the fertile soil. The news of fertile land quickly spread to other Mormon settlements throughout Arizona and Utah. Between 1881 and 1884, many settler families moved to the Gila River Valley. During this time, the settlements of Curtis,

, Layton, and McDonald were formed. The valley was transformed by a system of roads connecting churches, schools, and newsrooms throughout the valley. By 1885, the population of Pima (a settlement formerly known as Smithville) had grown to approximately 500 people.


Texan Ranchers

Texan ranchers also began emigrating to the Gila Valley. The 1880s brought drought, livestock diseases, overgrazing, and conflicts between ranchers in Texas. The sixth territorial governor of Arizona, Frederick A. Tritle, recognized a growing number of ranchers from Texas moving with their herds to Arizona in search of better grazing land. New railway lines made migration of families and cattle across the south easier. One notable migrant into the Gila River Valley from Texas was

, who moved over 1,800 cattle on railway cars and later became the sheriff of Gila County. The emigration of ranchers from Texas to Arizona increased settlement populations and changed the dynamics of early communities in the Gila Valley.


Mormon Settlers

The population of Graham Country increased sharply after various settlements spanning the Gila River Valley were founded. In 1883, many polygamist families fled to Southern Arizona and Mexico in order to escape federal prosecution and imprisonment under the new Edmunds Tucker Law, which banned the practice of polygamy in the United States and its territories. Many of these families settled in the Gila River Valley. This massive influx of people led General Authorities of the

. These farmers dug 40 miles of new irrigation canals and added between 15 to 20 miles to the pre-existing canals. A small number of farmers living in Smithville banded together to create a co-op called the “Smithville Irrigation and Manufacturing Company”, which established a mercantile headed by Hyrum Weech. In 1886, the construction of a railroad line to the mines in the Clifton and Morenci area brought an end to many freight lines as the railroad charged cheaper rates to transport goods. Because of this, many freighters began working for mines and businesses in the

Early Conflicts

Between the years of 1878-1883, there was confusion about where the border of the Gila Valley Indian Reservation was. A Mormon settlement called Forestdale was created in 1878, then vacated in 1880 when local Native Americans said the land was theirs. The Mormons returned in 1881 when rumors that the land wasn’t part of the Reservation had circulated, then abandoned it indefinitely when it was confirmed Forestdale was on the Reservation lands. This debate over borders and boundaries was a point of contention for early settlers in the Gila Valley who didn't have easy access to accurate maps. When rumors of gold in the Gila River spread in the 1870s, Americans and Mexicans began mining in the valley. Clashes between Americans, Mexicans, and Native Americans broke out constantly. One notable conflict began in 1872. The murder of Mexican settler Francisco Gandara and subsequent outrage of the local Mexicans resulted in several fatal clashes and strains in the diplomatic relations between the United States and Mexico. Gandara was shot by a vigilante gang of white Americans who blamed him for the disappearance of William McFarland, though no evidence was found to implicate Gandara. This event sparked what some call the “race wars” or the “war on the Gila.” Tensions between groups remained high for decades. A water crisis was declared in the 1870s due to Mexican and American settlements diverting the waters of the Gila River. The new towns of Adamsville and
