Stanislaus County is a county located in the Central Valley of the state of California. Based on the 2010 census, the population was 514,453. The county seat is Modesto. The county was created April 1, 1854. Stanislaus is named for a version of Estanislao, the baptismal name of a mission-educated renegade Indian chief who led a band of Indians in a series of battles against Mexican troops.

Stanislaus County comprises the Modesto Metropolitan Statistical Area.

Etymology - Origin of Stanislaus County Name

The word Stanislaus is a version of Estanislao, the baptismal name of a mission-educated renegade Indian chief who led a band of Indians in a series of battles against Mexican troops. He was finally defeated by General Mariano G. Vallejo in 1826. The county is named for the Stanislaus River, first discovered by Gabriel Moraga in 1806, and later renamed Rio Estanislao for the Indian chief.

Stanislaus County History

Stanislaus County was formed from part of Tuolumne County in 1854. Stanislaus County is a county located in the Central Valley of the state of California, between Stockton and Fresno. The county seat is Modesto.


Pre-European. In the area to be known as Stanislaus County, lived two native cultures: Miwoks and Yokuts. The Miwoks lived along the eastern side, primarily in the foothills, while the Yokuts lived in the valley.

October 1776. Spanish military officer Jose Joaquin Moraga traveled east from San Francisco and entered the San Joaquin Valley exploring for three days and wrote this description: "a great treeless, level plain, where no water was in evidence, while overhead the rays of the sun made themselves uncomfortably felt." It is not known if he entered the Stanislaus County area or not.

October 1806. Spanish Military officer Gabriel Moraga (son of Jose Joaquin Moraga) explored the inland area and is considered the first European to explore the area to later be known as Stanislaus County. He saw the Stanislaus River and named it Rio de Nuestra Senora Guadalupe. He returned in 1808 and 1810, exploring the inland area.

May 1829.         Two battles took place between Mexican soldiers and native people, led by ex-San Jose Mission Indian, Estanislao, near the junction of the Stanislaus and San Joaquin rivers. Estanislao was given his name by the mission padres in honor of Polish saint, St. Stanislaw.

Winter 1826-1827. American trapper, Jedediah Smith, with 15-20 men, traveled through the area to be known as Stanislaus County.

1829-1830. American trapper, Ewing Young, along with 20-year old Kit Carson, traveled through the area to be known as Stanislaus County.

1833. American trapper, Joseph Walker, traveled through the area to be known as Stanislaus County, with an expedition of 60 men who were sent by US Captain Bonneville from the Great Salt Lake area.

1843. The first settlements, in an area later to be known as Stanislaus County, were in the form of Mexican land grants. In November 1843, Mexican Governor Micheltorena granted land to Valentin Higuera and Rafael Feliz, which became known as El Pescadero, with 34,446 acres, located west of the San Joaquin River, bordering San Joaquin County. In December 1843, the governor granted land to Francisco Rica and Jose Castro, which became known as Rancheria del Rio Estanislao, with 48,887 acres, located north of Stanislaus River, bordering Tuolumne County. 

1844. Two additional land grants were sanctioned by the Mexican governor. In January 1844, the governor granted land to Mariano Hernandez, which became known as Rancho del Puerto, with 13,340 acres, located west of the San Joaquin River and south of Rancho Pescadero. In February 1844, the Mexican governor granted land to Sebastian Nunez, which became known as Rancho Orestimba, with 26,666, located west of the San Joaquin River and south of Rancho El Pescadero. 

March 27-April 1, 1844. Captain John C. Fremont explored the region to be known as Stanislaus County, while on a mapping expedition for the US Government. He wrote, "We came suddenly upon the Stanislaus River and hoped to find a ford, but the river was flowing by dark, deep, and swift, swollen by the mountain snows."

1846. Mexican Governor Pio Pico granted land to John Rowland, with 48,887 acres, which sometimes was called the San Joaquin and Stanislaus Land Grant. It was the same land that had been granted to Rica and Castro in 1843. Rowland didn't occupy his land until the Mexican War ended and then his land claim was validated by US Land Commission.

John C. Fremont traveled through the region to be known as Stanislaus County on his second expedition.

Mormon Sam Brannan brought settlers to a spot 1 1/2 miles north of the junction of the Stanislaus and San Joaquin rivers River, near present day Salida. On the south bank had been Estanislao's camp, and on the north bank (in today's San Joaquin County), Brannan established the settlement of New Hope or Stanislaus City. But, settlers of New Hope lived on both sides of the river, which meant they lived in the future Stanislaus County. Mormon President Brigham Young could not agree with Brannan to settle the Mormon people at New Hope instead of in the Valley of the Great Salt Lake. Many of the Mormon settlers went to the gold mines or to Utah abandoning the settlement.

June 13, 1846. Mexican Governor Pio Pico granted land to Alfias Basil Thompson, which would become known as Thompson's Ranch with 35,533 acres and located west of Rancheria del Rio Estanislao. A legal problem arose since the Pico granted the land to Thompson a month after the United States declared war on Mexico, but prominent Americans in California testified that Thompson had accepted the land in good faith and hence retained title. The Land Commission fixed the date of July 7, 1846 as the end of Mexican authority in California, which meant Thompson's claim was legal having been granted the land nearly a month before Mexican authority had ceased.

1849. Grayson or Graysonville was founded by a company of seven men, which included John Westley Van Benscroten and Andrew Jackson Grayson. It was located on the west bank of the San Joaquin River near the mouth of the Stanislaus River. The town was named for Grayson because he was the oldest member of the company. Grayson was a native of Louisiana, active in the Mexican War of 1846 and an authority of Pacific Coast birds. Van Benscroten was a native of New York City and came to California with Captain Fremont in 1846.

Paxton McDowell and Major R.D. Hammond founded Tuolumne City, which was located five miles upstream on the north bank of the Tuolumne River.

Dr. Adams founded the town of Adamsville, on the south bank of the Tuolumne River, three miles above Tuolumne City.

Either Benson & Byers or a Mr. Townsend founded the town of Crescent City, near the site of present day Modesto.

The town of Knights Ferry was founded by trapper and hunter William Knight. Knight had been with Fremont's expedition and felt the site perfect for a ferry crossing. The first county bridge was located at Knights Ferry, which washed away during 1862 flood, but later rebuilt.

Early 1850s. There were many settlements and river ferries located along the three rivers in the Stanislaus County area. Hillgard and Burman Ferry was located west of Salida on the Stanislaus River. Murphy's Ferry was further upstream. Major Burney's Burneyville Ferry was at present day Riverbank where the current bridge stands. Further up the river at Lover's Leap stood Keeler's Ferry and further up was Knights Ferry. On the Tuolumne River, beginning near the junction with the San Joaquin River were the following ferries and settlements: Tuolumne City, Paradise City, Adamsville, Westport Landing, Whitmore Ferry (where Southern Pacific RR bridge is located, Empire City, Baker's Ferry (Waterford), Dickinson's Ferry (Robert's Ferry), and La Grange. On the San Joaquin River, beginning at the Merced County line were the ferries: Hill's Ferry, Blair's Ferry, Russell's Ferry, Ward's Ferry, and Turner's Ferry.

1850. John S. Marvin, a lawyer from Boston, founded the town of Empire City, on the south bank of the Tuolumne River, just above Crescent City.

Jesse Hill established Hill's Ferry, just north of the junction of the Merced and San Joaquin rivers, on the Orestimba Rancho.

1852. French Bar or La Grange was founded. Elam Dye located his rancho along the Tuolumne River, which would be the site of booming town of La Grange. About the same time, French miners struck gold on a bar in the river (French Bar), which drew a more miners, and by 1854 there were over hundred buildings in the new town of La Grange.

1854. The county's first public school opened at Newsom's Bridge near Orestimba Creek.

June 10, 1854. The first county election was held and Adamsville was selected as the county seat by thirty votes over Empire City. Adamsville was founded in 1849 by the county's first practicing physician, Dr. David Adams, and had a hotel, ferry and a few scattered residences. H.W. Wallis was elected County Judge; William D. Kirk as County Sheriff; Robert McGarvey as Clerk and Recorder; and S.P. Scaniker as District Attorney.

November 8, 1870. The construction of the Central Pacific Railroad reached a station to be named after railroad director and financier William C. Ralston, but Ralston turned down the honor, and the station instead was named Modesto, which is Spanish for modest.

April 2, 1875. William Dona was executed on the county courthouse grounds in Modesto for the saloon shooting of James Connolly. The scaffolding was borrowed from San Joaquin County and was surrounded by a high board fence to screen out the public, except for certain witnesses prescribed by law.

October 6, 1875. A jackrabbit drive was organized near Turlock in which 413 rabbits were killed. The rodent had become a real nuisance to farming because of its eating grain sprouts and seed.

1877. Lack of winter rain destroyed the county's grain crop. One writer described the condition, "In forty-two miles there is not a spear of green grass nor a blade of wheat to be seen. The isolated farmhouses presented an aspect of poverty. Many of them are deserted and the farmers and their families have gone to other places to find employment. Some of the farmers, more fortunate, have wells of water and their farms are quite thrifty around their dwellings."
