Pinal County History

 


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 county.

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.
