Santa Ana (Spanish for ‘Saint Anne’) is the county seat of Orange County, California. Located in the Greater Los Angeles region of Southern California, the city’s population was 310,227 at the 2020 census, making Santa Ana the second most populous city in Orange County (after Anaheim), the 13th-most populous city in California, and the 64th densest large city in the United States. Santa Ana is a major regional economic and cultural hub for the Orange Coast.

Santa Ana’s origins began in 1810, when the Spanish governor of California granted Rancho Santiago de Santa Ana to José Antonio Yorba. Following the Mexican War of Independence, the Yorba family rancho was enlarged, becoming one of the largest and most valuable in the region and home to a diverse Californio community. Following the American Conquest of California, the rancho was sold to the Sepúlveda family, who subsequently lost their land claim. In 1869, William H. Spurgeon then purchased the rancho and formally founded the modern city of Santa Ana.

Approximately four-fifths Latino, Santa Ana has been characterized by The New York Times as the “face of a new California, a state where Latinos have more influence in everyday life—electorally, culturally and demographically—than almost anywhere else in the country.”

Members of the Tongva and Juaneño/Luiseño are indigenous to the area. The Tongva called the Santa Ana area “Hotuuk.” The village of Pajbenga was located at modern day Santa Ana along the Santa Ana River.

After the 1769 expedition of Gaspar de Portolá out of Mexico City, then capital of New Spain, Friar Junípero Serra named the area Vallejo de Santa Ana (Valley of Saint Anne, or Santa Ana Valley). On November 1, 1776, Mission San Juan Capistrano was established within this valley.

In 1810, the first year of the Mexican War of Independence, Jose Antonio Yorba, a sergeant of the Spanish army, was granted land that he called Rancho Santiago de Santa Ana. Yorba’s rancho included the lands where the cities of Olive, Orange, Irvine, Yorba Linda, Villa Park, Santa Ana, Tustin, Costa Mesa and unincorporated El Modena, and Santa Ana Heights, are today. This rancho was the only land grant in Orange County granted under Spanish Rule. Surrounding land grants in Orange County were granted after Mexican Independence by the new government.

After the Mexican-American war ended in 1848, Alta California became part of the United States and American settlers arrived in this area.

Santa Ana was listed as a township of Los Angeles County in the 1860 and 1870 census, with an area encompassing most of what is now northern and central Orange County. It had a population of 756 in 1860 and 880 in 1870. The Anaheim district was enumerated separately from Santa Ana in 1870.

Claimed in 1869 by Kentuckian William H. Spurgeon on land obtained from the descendants of Jose Antonio Yorba, Santa Ana was incorporated as a city in 1886 with a population of 2000 and in 1889 became the seat of the newly formed Orange County.

In 1877, the Southern Pacific Railroad built a branch line from Los Angeles to Santa Ana, which offered free right of way, land for a depot, and $10,000 in cash to the railroad in exchange for terminating the line in Santa Ana and not neighboring Tustin. In 1887, the California Central Railway (which became a subsidiary of the Atchison, Topeka and Santa Fe Railway the following year) broke the Southern Pacific’s local monopoly on rail travel, offering service between Los Angeles and San Diego by way of Santa Ana as a major intermediate station.

In 1890, whites made up 71 percent of the city’s population, most of whom migrated to Santa Ana from confederate states following the American Civil War in search of real estate ventures and other economic opportunities.

By 1905, the Los Angeles Interurban Railway, a predecessor to the Pacific Electric Railway, extended from Los Angeles to Santa Ana, running along Fourth Street downtown. Firestone Boulevard, the first direct automobile route between Los Angeles and Santa Ana, opened in 1935; it was enlarged into the Santa Ana Freeway in 1953. The Pacific Electric Santa Ana Line ran from 1905 to 1958.

Santa Ana was the home of the original Glenn L. Martin aviation company, founded in 1912 before merging with the Wright Company in 1916. Later, Glenn Luther Martin created a second company of the same name in Cleveland, Ohio which eventually merged with the Lockheed Corporation to form the largest defense contractor in the world, Lockheed Martin.

Although there was a significant wave of Mexican migration to the city following the 1910 Mexican Revolution, the city remained majority white in 1939.

During World War II, the Santa Ana Army Air Base was built as a training center for the United States Army Air Forces. The base was responsible for continued population growth in Santa Ana and the rest of Orange County as many veterans moved to the area to raise families after the end of the war.

Santa Ana was at the center of Orange County’s economic boom in the 1950s with its agricultural and defense industries. However, most of this prosperity was only experienced by the city’s white residents, while Latinos did not similarly benefit. Instead, economic inequality between the two groups rapidly increased during this time.

In 1958, the Honer Plaza and Bullock’s Fashion Square malls opened and would supplant Downtown Santa Ana, with its department stores such as Rankin’s, Ward’s, Penney’s and Buffums. Fashion Square was completely renovated and became MainPlace Mall in 1987.

By the 1970s, Santa Ana was becoming an increasingly Latino city, with white flight to surrounding suburbs coinciding with the city’s downtown becoming increasingly frequented by Latinos. This changed perceptions of the city and its economic value, with property values dropping significantly by 1974, while surrounding cities of Laguna Beach, Newport Beach, and Villa Park increased in value.

Santa Ana entered the 1980s as a city of equal numbers of whites and Latinos. What had been the white commercial center of the city, Fourth Street, was now a street of Latino businesses and character. Latino immigrant and working-class families could now be found in every neighborhood of the city, rather than in just a few ethnic enclaves, as they were previously. Santa Ana became more often referred to as Santana and Fourth Street as La Cuatro.

Having been a charter city since November 11, 1952, the citizens of Santa Ana amended the charter in November 1988 to provide for the direct election of the Mayor who until that point had been appointed from the council membership. Miguel A. Pulido was the first mayor of Latino descent in the city’s history and the first Mayor directly elected by the voters.

Since the 1980s, Santa Ana has been characterized by an effort to revitalize the downtown area which had declined in influence, even as it had become a dynamic commercial and entertainment center for working-class Latinos. The Santa Ana Artist’s Village was created around Cal State Fullerton’s Grand Central Art Center to attract artists and young professionals to live-work lofts and new businesses. The process continued into 2009 with the reopening of the historic Yost Theater.

In the 2010s, gentrification became a larger concern of Santa Ana residents, with its roots starting in the 1990s. Despite strong Latino political representation, gentrification efforts have increasingly displaced the Mexican immigrant presence in the downtown area of the city in favor of outsiders. Primarily Spanish-speaking businesses that served immigrant populations have been demolished in favor of arts projects to draw in outside investment, which bring clientele who further question why Spanish-speaking businesses are present, leading to a cycle of displacement.

Residents formed a social movement to address lead concentrations in lower-income areas of the city. A 2020 study found that areas of Santa Ana with a median income below $50,000 had five times higher lead concentrations than higher-income areas of the city, which is particularly a concern for children. Residents continue to advocate for environmental justice in the city.

Santa Ana is located at 33°44′27″N 117°52′53″W / 33.74083°N 117.88139°W / 33.74083; -117.88139 (33.740717, -117.881408).

According to the United States Census Bureau, the city has a total area of 27.5 square miles (71 km). 27.3 square miles (71 km²) of it is land and 0.2 square miles (0.52 km) of it (0.90%) is water. With 12,471.5 people per sq. mile, it is the fourth-most densely populated city in the United States with a population of 300,000 or more.

Santa Ana is nested on flat, low-lying plains with little land elevation change. Running through the west end of the city is the mostly channelized Santa Ana River, which is also largely seasonal due to the construction of the Prado Dam and Seven Oaks Dam. The river has caused several severe floods in the 20th century, and is a continued threat despite the existence of the dams.

Now fully developed, Santa Ana has several distinct districts. The core of the city is the downtown area, which contains both retail and housing, as well as the Santa Ana Civic Center, which is a dense campus of administrative buildings for both the city and the county of Orange. The civic center is also home to the Ronald Reagan Federal Building and Courthouse. Several historic homes dating from the late 1800s can be found as well, and their preservation is a key issue as development of the downtown area continues.

North of downtown is the “Midtown” district along Main St., home to entertainment destinations such as the Bowers Museum, MainPlace Mall, and the Discovery Science Center.

Near the intersection of the Santa Ana Freeway and the Costa Mesa Freeway is the newly designated “Metro East” area, which the city council has envisioned as a secondary mixed-use development district. Currently the area is occupied by several office towers, but little retail or housing. Also on the east side of the city is the Santa Ana Zoo, notable for its collection of monkeys and species from South and Central America.

The southeast end of the city is part of the South Coast Metro area, which is shared with the city of Costa Mesa. South Coast Plaza, a major shopping center, is the primary destination of this area, which also contains several high-rise office and apartment buildings. Yokohama Tire Corporation’s United States headquarters are located at 1 MacArthur Place in the South Coast Metro area of Santa Ana, and Banc of California’s headquarters relocated from the neighboring city of Irvine.
