The area now known as Fresno County was the traditional homeland ofYokuts andMono peoples, and was later settled by Spaniards during a search for suitable mission sites. In 1846, this area became part of the United States as a result of theMexican-American War.
Fresno County was formed in 1856 from parts ofMariposa,Merced andTulare counties.Fresno isSpanish for "ash tree"[9] and it was in recognition of the abundance of the shrubby local ash,Fraxinus dipetala, growing along theSan Joaquin River that it received its name. Parts of Fresno County's territory were given toMono County in 1861 and toMadera County in 1893. The originalcounty seat was along the San Joaquin River inMillerton, but was moved to the rapidly growing town of Fresno on the newly built Southern Pacific Railroad line. A special election was held on March 23, 1874, to decide if Millerton should remain the County Seat or if the County Seat should be moved to another location. Fresno won the election that day and became the new Fresno County Seat.
The settling of Fresno County was not without its conflicts, land disputes, and other natural disasters. Floods caused immeasurable damage elsewhere and fires also plagued the settlers of Fresno County. In 1882, the greatest of the early day fires wiped out an entire block of the city of Fresno, and was followed by another devastating blaze in 1883.
At the same time residents broughtirrigation, electricity, and extensiveagriculture to the area. In 1865,William Helm brought his sheep to Fresno county, which was then a vast space of open land. Helm was the largest individual sheep grower in Fresno County. Moses Church developed the firstcanals, called "Church Ditches", forirrigation. Thesecanals allowed extensive cultivation ofwheat. Francis Eisen, leader of the wine industry in Fresno County, also began theraisin industry in 1875, when he accidentally let some of his grapes dry on the vine. Anthony Easterby and Clovis Cole developed extensive grain and cattle ranches. These and other citizens laid the groundwork for the cultivation of Fresno County – now one of the nation's leading agricultural regions. In more recent times cotton became a major crop in Fresno and the southern San Joaquin Valley, but recent drought and lower demand have lessened cotton's importance to the local economy.[citation needed]
The discovery of oil in the western part of the county, near the town ofCoalinga at the foot of theCoast Ranges, brought about an economic boom in the 1900s (decade), even though the field itself was known at least as early as the 1860s. By 1910,Coalinga Oil Field, the largest field in Fresno County, was the most richly productive oil field in California; a dramaticoil gusher in 1909, the biggest in California up until that time, was an event of sufficient excitement to cause theLos Angeles Stock Exchange to close for a day so that its members could come by train to view it. The Coalinga field continues to produce oil, and is currently the eighth-largest field in the state.[10][11]
More than thirty structures in Fresno County are on the National Register of Historic Places, including theFresno Water Tower, which once held over 250,000 US gallons (950 m3) of water for the city of Fresno, theMeux Home, andKearney Mansion Museum.[citation needed]
According to theU.S. Census Bureau, the county has a total area of 6,011 square miles (15,570 km2), of which 5,958 square miles (15,430 km2) is land and 53 square miles (140 km2) (0.9%) is water.[12]
Fresno County consists of about 38 smaller towns including Fresno, Selma, Parlier, Clovis, Reedley, Sanger, Kerman, Kingsburg, Coalinga, Firebaugh, Calwa, Friant, Mendota, Fowler, Shaver Lake, San Joaquin, Orange Cove, Del Ray, Yokuts Valley, Auberry, Huron, Caruthers, Riverdale, Laton, Big Creek, Tranquility, Biola, Raisin City, Easton, Three Rocks, Cantou Creek, Lanare, Minkler, Mayfair, Malaga, Bowles, Monmouth, and West Park.[13][14]
Fresno County is part of theMadera AVAwine region. However, Fresno was named after two particular ash trees that grew near the town of Minkler on the Kings River, one of which is still alive and standing.[citation needed]
In October2019, theBureau of Land Management ended a five-year moratorium on leasing federal land in California to fossil fuel companies, opening 725,000 acres (1100 sq. miles; 29,000 ha) to drilling inSan Benito,Monterey, and Fresno counties.[17]

From Fresno County's incorporation in 1856, it voted Democratic in every election until1904, when PresidentTheodore Roosevelt stood for re-election. Fresno County backed Roosevelt over his Democratic opponentAlton B. Parker. This did not immediately change the county's voting tendencies, however. It supported southern DemocratWoodrow Wilson in the elections of1912 and1916.
Fresno County was generally Republican from the onset of the "roaring 1920s" until the Great Depression, when PresidentFranklin D. Roosevelt forged the New Deal Coalition that benefitted the agrarian county. From1932 to1976, the county consistently votedDemocratic, barringRichard Nixon's landslide victory over former SenatorGeorge McGovern (D-SD) in1972.
With PresidentJimmy Carter's defeat byRonald Reagan, Fresno became a GOP-leaning swing county. It barely favored Reagan's successor (then) vice presidentGeorge H. W. Bush in1988.

Republicans won elections in Fresno County by increasing margins from1996 to2004, then again in2024.

In contrast, gubernatorial elections are considered safe for Republicans in the county. It voted "Yes" in the2021 gubernatorial recall election and has voted for the Republican gubernatorial candidate in every election since1978.
