Indigenous peoples of California referred to by the Spanish asGabrielenos, known as theTongva, lived in the area for thousands of years. One estimate wrote that the native population in what was to become northern Orange County was at least 1,000.[11] The large village ofHutuknga was closely situated to the area that is now Placentia.[12]
In 1837, the Mexican government granted the area that is now Placentia to Juan Pacifico Ontiveros as part of theRancho San Juan Cajón de Santa Ana land grant.[13]
In 1865, American pioneerDaniel Kraemer arrived and purchased 3,900 acres (1,600 ha). Many other American pioneers soon followed, and the community developed.[13]
The local school district was originally named the Cajon School District. In 1878, the school district's name was changed to Placentia School District by Sarah Jane McFadden, Placentia being derived from a Latin word meaning "pleasant place to live". She was the wife of William McFadden, who was the second White settler to arrive in Placentia.[14] The town eventually took its own name after the school district.[13]
The first commercial orange grove was established in 1880, worked by mostly Mexican and English laborers.[11]

From a handful of scattered ranches, the core of the town was developed around 1910. It functioned as a major railroad stop along theSanta Fe Railroad for processing oranges. Later, during theGreat Depression, a brief strike of citrus workers occurred in Placentia.[11]
Oil was found in 1919, which led to the development of numerous oil wells in eastern and northern Placentia. The town of Richfield, which later becameAtwood, was built to house oil workers. Mexican laborers formed the majority of the labor force in the oil industry. The neighboring town ofLa Jolla, Placentia was constructed for a similar reason as a segregatedcolonia.[11]
Several schools were constructed in Placentia from the 1910s to the 1930s that weresegregated between White and Mexican students.[11] Isabel Martínez was the first student of Mexican parentage to graduate fromFullerton High School in 1931, being celebrated in thePlacentia Courier as an "exceptional" Mexican. Within six years, the number of Placentia students graduating high school numbered only six.[15]
The predominately Mexican areas of Placentia were heavily hit by theSanta Ana Riverflood of 1938, which destroyed everything in the area but "the La Jolla School Building and three brick structures." The flood left 3,700 refugees and 1,500 homes uninhabitable, and "caused more than 50 deaths, most from the Atwood area."[16]
Mexican-Americanwar veterans fromWorld War II worked to end school segregation in Placentia in 1948.[11] This campaign was led by Alfred Aguirre, who noted that some white ranchers believed Mexicans were good fruit pickers, but that "the White kids are too advanced" for Mexican students to keep up in the classroom.[17]
The Mexican-American community in Placentia developed its own political power base in the 1950s. This resulted in the election of Aguirre to Placentia's city council from 1958 to 1962 and the registration of hundreds ofChicano voters in the city.[17]
In July 2020, Placentia organized and established its own fire department, Placentia Fire and Life Safety Department, leaving theOrange County Fire Authority as the first city to ever disband from the OCFA.[13]

Placentia has a $20 millionMetrolink project that started in the downtown area in 2013.[clarification needed] This project is in conjunction with theOrange County Transit Authority (OCTA), and will assist in the continued revitalization of the area, which is also scheduled for the building of more transit-oriented housing to complement the train station, mixed use, retail, and entertainment.[45] All are designed to enhance Placentia's unique presence in Orange County. Placentia is also working with the OCTA on the OC Bridges project. The project, combined with the city of Fullerton, provides around $580 million in funding to build underpasses and/or overpasses at the major north–south roadways in the two cities. The roadways are Lakeview Avenue, Rose Drive/Tustin Avenue, Orangethorpe Avenue, Kraemer Boulevard, Placentia Avenue, State College Boulevard, and Raymond Avenue. The underpasses and overpasses at Placentia, Kraemer, Rose/Tustin and Lakeview are complete.[46][47]

Aranda was invited by a professor at UCI. The following year, the chairman of Toltecas en Aztlan, and the board director of the Centro Cultural De La Raza, Guillermo Aranda, also invited these same Orange County artists referred to as the "Santa Ana muralists/Santa Ana artists", to come toChicano Park and paint on one of the first pillars (second painted pillar) of Chicano Park.

A tentative completion date was set for June 2022, but construction is now "on hold" pending further negotiations withBNSF.[67]
In 2007, the city becamethe first city to implement a quiet zone[68] for the cargo-carrying trains that pass through the city daily, using locomotive grade-crossing predictors and intercrossing ground-based radio communications to effect a corridor where crossing gate arms become actuated prior to the train's approach, enabling trains to not be required to announce their approach by sounding theMorse code letter "Q" on their whistles, which is otherwise mandated by theFederal Railroad Administration. The city'sQuiet-Zone-Update web pages offer information on the zone's scope and any temporary or long-term alterations to the quiet zone.
