Prior to the arrival of the Spanish in Alta California, the area that now comprises Downey was inhabited by the Tongva ethnic group, which came to be called the Gabrielino by the Spanish.
Spanish colonial history of the area today known as Downey dates back to 1771 with the founding of the Mission San Gabriel Arcangel, a California State historical landmark. The founding of the mission and mission lands establishes the birthplace of the modern Los Angeles region.
In 1784, Governor Pedro Fages granted to former solider Manuel Nieto (1734-1804) the largest of the land concessions made during the Spanish control of California. Its 300,000 acres (1,200 km²) stretched from the Santa Ana River on the east to the Old San Gabriel River (now the Rio Hondo and Los Angeles River) on the west, and from the mission highway (approximately Whittier Boulevard) on the north to the ocean on the south. Its acreage was slightly reduced later at the insistence of Mission San Gabriel on whose lands it infringed. The Spanish concessions, of which 25 were made in California, were unlike the later Mexican land grants in that title was not transferred, but were similar to grazing permits, with the title remaining with the Spanish crown. [1]
The Rancho Los Nietos passed to Manuel Nieto's four children upon his death and remained intact until, in 1833, his heirs petitioned Mexican Governor José Figueroa to partition the property. The northwestern portion of the original rancho, comprising the Downey-Norwalk area, was granted as Rancho Santa Gertrudes to Josefa Cota, the widow of Manuel's son, Antonio Nieto. At approximately 21,000 acres (85 km²), Santa Gertrudes was itself a sizable rancho and conatined the old Nietos homestead, which was a center of social life east of the pueblo of Los Angeles.[2]
After the Mexican-American war concluded in 1848, many of the Californio ranchos were obtained by affluent Anglo-Americans who were immigrating west under the United States manifest destiny doctrine, and marrying into established Californio Spanish families.
Downey was founded by and named for the former Civil War governor of California, John Gately Downey, when he subdivided land he procured between the Rio Hondo and the San Gabriel River. The Southern Pacific Railroad arrived in 1873, and farmers in the area grew grain, corn, castor beans and fruit until around 1940.
Downey was incorporated in 1956, and instituted a charter form of government in 1964. Suburban homes and factories replaced the farms after World War II. The largest employer was originally Vultee Aircraft, then North American Aviation, (later North American Rockwell, then Rockwell International which was then bought by the Boeing company) whose facilities produced some of the systems for the Apollo Project as well as the space shuttle. The seventy year history of airplane and space vehicle manufacturing in Downey came to an end when the Rockwell plant closed in 1999. The former Rockwell plant has been converted to the Downey Landing shopping complex, a Kaiser Permanente hospital, a park, a space museum and [Downey Studios].

Near the center of the city lies what was once one of the busiest intersections in the world, the intersection of Lakewood Boulevard (State Route 19) and Firestone Boulevard (former State Route 42). Route 19 was a major thoroughfare between Pasadena and the port at Long Beach, and Route 42 was part of the old Spanish Trail system that connected Los Angeles to San Diego.
In the 1960s the town's Downey Records achieved a small notoriety with recordings like The Chantays' surfing instrumental "Pipeline." Downey's two main public high schools are named for Governor Downey and Governor (and later, Chief Justice) Earl Warren.
Downey is home to Rancho Los Amigos National Rehabilitation Center, which is the main public rehabilitation hospital for Los Angeles County. Rancho Los Amigos is renowned worldwide for its innovative contributions to the care of spinal cord injuries and post-polio syndrome.
