Members of the Tongva, Juaneño, and Luiseño Native American groups long inhabited the area. After the 1769 expedition of Gaspar de Portolà, a Spanish expedition led by Junipero Serra named the area Valle de Santa Ana (Valley of Saint Anne). On November 1, 1776, Mission San Juan Capistrano became the area’s first permanent European settlement. Among those who came with Portolá were José Manuel Nieto and José Antonio Yorba. Both these men were given land grants—Rancho Los Nietos and Rancho Santiago de Santa Ana, respectively. The Nieto heirs were granted land in 1834. The Nieto ranches were known as Rancho Los Alamitos, Rancho Las Bolsas, and Rancho Los Coyotes. Yorba heirs Bernardo Yorba and Teodosio Yorba were also granted Rancho Cañón de Santa Ana (Santa Ana Canyon Ranch) and Rancho Lomas de Santiago, respectively. Other ranchos in Orange County were granted by the Mexican government during the Mexican period in Alta California.
A severe drought in the 1860s devastated the prevailing industry, cattle ranching, and much land came into the possession of Richard O’Neill, Sr., James Irvine and other land barons. In 1887, silver was discovered in the Santa Ana Mountains, attracting settlers via the Santa Fe and Southern Pacific Railroads.
Los Angeles County before the secession of Orange County in 1889
After several failed attempts in previous sessions, the California legislature passed a bill authorizing the portion of Los Angeles County south of Coyote Creek to hold a referendum on whether to remain part of Los Angeles County or to secede and form a new county to be named “Orange” as directed by the legislature. Such referendum required a 2/3 vote for secession to take place, and subsequently on June 4, 1889, the residents south of Coyote Creek voted 2,509 to 500 in favor of secession. After such referendum, Los Angeles County filed three lawsuits in the courts to stall and stop the secession from occurring, but such attempts were futile. On July 17, 1889, a second referendum was held south of the Coyote Creek to determine if the county seat of the to-be county to be in either Anaheim or Santa Ana, along with an election for every county officer. In the end, Santa Ana defeated Anaheim in such referendum. With the referendum taken place, the County of Orange was officially incorporated on August 1, 1889, as prescribed by state law. Since the date of the incorporation of the county, the only geographical changes to have occurred which affected Orange County was when the County and Los Angeles County agreed to trade land around Coyote Creek to adjust the border of the two counties to conform with city blocks.
The county is said to have been named for the citrus fruit in an attempt to promote immigration by suggesting a semi-tropical paradise – a place where anything could grow.

Other citrus crops, avocados, and oil extraction were also important to the early economy. Orange County benefited from the July 4, 1904, completion of the Pacific Electric Railway, a trolley connecting Los Angeles with Santa Ana and Newport Beach. The link made Orange County an accessible weekend retreat for celebrities of early Hollywood. It was deemed so significant that Pacific City changed its name to Huntington Beach in honor of Henry E. Huntington, president of the Pacific Electric and nephew of Collis Huntington. Transportation further improved with the completion of the State Route and U.S. Route 101 (now mostly Interstate 5) in the 1920s.
Agriculture, such as that involving the boysenberries made famous by Buena Park native Walter Knott, began to decline after World War II. However, the county’s prosperity soared during this time. The completion of Interstate 5 in 1954 helped make Orange County a bedroom community for many who moved to Southern California to work in aerospace and manufacturing. Orange County received a further boost in 1955 with the opening of Disneyland.
In 1969, Yorba Linda-born Orange County native Richard Nixon became the 37th President of the United States.
In the 1980s, Orange County had become the second most populous county in California as the population topped two million for the first time.
In 1994, an investment fund meltdown led to the criminal prosecution of treasurer Robert Citron. The county lost at least $1.5 billion through high-risk investments in bonds. The loss was blamed on derivatives by some media reports. On December 6, 1994, the County of Orange declared Chapter 9 bankruptcy, from which it emerged on June 12, 1996. The Orange County bankruptcy was at the time the largest municipal bankruptcy in U.S. history.
In recent years, land use conflicts have arisen between established areas in the north and less developed areas in the south. These conflicts have regarded issues such as construction of new toll roads and the repurposing of a decommissioned air base. El Toro Marine Corps Air Station was designated by a voter measure in 1994 to be developed into an international airport to complement the existing John Wayne Airport. But subsequent voter initiatives and court actions have caused the airport plan to be permanently shelved. Instead, it became the Orange County Great Park.
