The State of Arizona takes its name from a ranch started by Bernardo de Urrea sometime between 1734 and 1736. The general area around his ranch was also known as Arizona. He and a majority of the first explorers, settlers, and miners in the area were Basque and it is they who probably gave the Basque name Arizona (the good oak) to the region. Oak trees are abundant both at the original ranch and the entire area between present-day Nogales, Arizona and Saric, Sonora. Bernardo de Urrea's Arizona Ranch lies about 40 miles southwest of Tumacácori in what is today Sonora, Mexico.
Prospecters and miners rushed to the area of the great silver discovery of October,1736. It was given the name San Antonio de Padua by Justicia Mayor Juan Bautista de Anza when he arrived on the scene in November and ordered that all the silver that had been taken from the site be impounded and brought to Urrea's Arizona Ranch, some fifteen miles down the canyon. Because his escribano (scribe), Manuel José de Sosa, dated all the impounding documents at Arizona, people in faraway places like Guadalajara and Mexico City were soon referring to the silver as the "silver of Arizona." Thus, Arizona quickly became a household word associated with great and sudden wealth. Contrary to popular myth, however, the silver, or the area, were never referred to as Arizonac, even though both Arizona and Arizonac are viable Basque words. Arizona is simply singular (the good oak tree) and Arizonac is plural (the good oak trees).
