History

File:Santa Cruz River - Kino Springs AZ.jpg

Santa Cruz County, formed on March 15, 1899, out of what was then Pima County, is named after the Santa Cruz River. The river originates in the Canelo Hills in the eastern portion of the county, crosses south into Mexico near the community of Santa Cruz, Sonora, and then bends northwards returning into the United States (and Santa Cruz County) east of Nogales.

Father Eusebio Kino, an Italian explorer and missionary in the service of the Spanish Empire, named the Santa Cruz River–"holy cross" in Spanish–in the 1690s. In addition, Kino founded several missions to evangelize the different O'odham peoples living along the banks of the Santa Cruz River, including Missions San Cayetano del Tumacácori (1691) and San Gabriel de Guevavi (1691), as well as Los Reyes de Sonoita (1692) near Sonoita Creek. Along the river, but outside the boundaries of Santa Cruz County, Kino also founded Mission San Xavier del Bac (1692) near Tucson, Arizona, and Mission Santa Maria del Pilar (1693) in what is now Santa Cruz, Mexico. Kino's San Cayetano and San Gabriel missions were destroyed in the O'odham peoples' 1751 Pima Revolt and rebuilt as Missions Los Santos Ángeles de Guevavi (1751), San José de Tumacácori (1753), and San Cayetano de Calabazas (1756). The ruins of all three of these later missions are now protected by Tumacácori National Historical Park. Disease, warfare, overwork, and changes in land ownership during Spanish colonization led to the demographic decline of the O'odham peoples of Santa Cruz County.{{cite web|url=http://jp.pima.gov/Pages/history/county.htm|title=History: Pima County|publisher=Pima County Justice Court|date=September 27, 2000|access-date=September 30, 2009|url-status=dead|archive-url=https://web.archive.org/web/20100527140505/http://jp.pima.gov/Pages/history/county.htm|archive-date=May 27, 2010}}{{cite web|url=http://www.lib.az.us/archives/county_santa_cruz.cfm|title=Santa Cruz County|publisher=Arizona State Library Archives and Public Records: Arizona History and Archives Division|date=August 4, 2009|access-date=September 30, 2009|url-status=dead|archive-url=https://web.archive.org/web/20090915204127/http://www.lib.az.us/archives/county_santa_cruz.cfm|archive-date=September 15, 2009}}

Owing to its border location and Hispanic majority population, Santa Cruz is a strongly Democratic county, but it has been shifting Republican by considerable numbers. The last Republican to win the county was George H. W. Bush in 1988, and although the Republicans won the county in six consecutive elections from 1968 to 1988, three of these wins were by very narrow margins. Following the trends seen in majority Hispanic counties across the United States, Joe Biden defeated Donald Trump with 67.1% of the popular vote in the county, a slightly lower margin than Hillary Clinton's 71.1% vote share in 2016. Trump's gains were far higher than Biden's losses (at nearly 8%), due to a combination of third parties losing votes and higher turnout. Despite this rightward shift in the vote share, Santa Cruz County remained as the most Democratic-leaning county in Arizona until 2024, when Apache and Coconino counties voted slightly more Democratic than Santa Cruz County, as Trump had the best performance for a Republican in the county since their last win in 1988, cracking 40% in the county for the first time since then.

Notable People

Elizabeth Gutfahr, former elected county treasurer who confessed to embezzling more than $38 million between 2012 and 2024.{{Cite web |date=2024-11-24 |title=Arizona county treasurer pleads guilty to embezzling more than $38 million for personal expenses |url=https://www.yahoo.com/news/arizona-county-treasurer-pleads-guilty-213845800.html |access-date=2024-11-24 |website=Yahoo News |language=en-US}}

Economy

Because it is the state's smallest county, Santa Cruz County's economic activity is also smaller. Its agriculture consists primarily of forage/hay, and the cattle products raised on that pasture and hay are almost 100% of farm products annually.{{cite web | access-date=July 29, 2022 | date=2017 | title=Census of Agriculture - State and County Profiles - Arizona | website=USDA, National Agricultural Statistics Service | url=https://www.nass.usda.gov/Publications/AgCensus/2017/Online_Resources/County_Profiles/Arizona/}}
