Pinal County History

Pinal County, Arizona


Pinal County experienced slight modifications in 1877 to correct a boundary error, and it also lost the Globe District of southern Gila in 1881. Its present area is 3,441,920 acres. Included in it are the Gila River (forming part of its boundary) and part of the San Carlos Indian Reservation. Pinal County varies in its characteristics from the agricultural land around its county seat at Florence to the mountains where many rich mining discoveries have been made.

In 1871, the Territorial Legislature designated 5,324 miles of some of Arizona's prime land as Pinal County. Pinal County was formed out of portions of Maricopa and Pima Counties on February 1, 1875. Florence, Arizona was established in 1866, was designated as, and has remained, the County seat. Arizona became a state in 1912. It has flown the flags of Spain, Mexico, the Confederacy and the Union. It derives its name from the Pinal Apaches or "pine groves in the mountains." There are four Indian Nations - the Maricopa-Pima (Ak-Chin), Gila River, Tohono O'Odham and San Carlos Apache in Pinal County. They occupy twenty-three percent of the counties.

This area which housed America's first civilization, the capitol of the Toltecs, the Walled Cities of the Aztecs, the father of American irrigation, and the friendly Pima Indians now has vast farming areas and grows such things as cotton, vegetables, and fruit. A lot of migrant workers made their homes in Pinal County. Also, Pinal County had a lot of copper mining but most of the mines have closed now. These mines brought in a lot of workers in the early 1920's.
