Native American For over 8,000 years, the site of Arcadia was part of the homeland of the
Tongva people ("Gabrieleño" tribe), a
Californian Native American tribe whose territory spanned the greater
Los Angeles Basin, and the San Gabriel and
San Fernando Valleys. Their fluid borders stretched between the
Santa Susana Mountains,
San Bernardino Mountains, and
San Gabriel Mountains in the north; the
Santa Monica Mountains and
Simi Hills in the west; the
San Jacinto Mountains and
Santa Ana Mountains in the east; and the coast and
Catalina Island (
Pimu) in the south. A
Tongva settlement site within present-day Arcadia was known as
Alyeupkigna (or Aluupkenga).
Rancho period The town's site became part of the Spanish
Mission San Gabriel Arcángel lands in 1771. After
Indian Reductions to become
Mission Indians, the Tongva were known as the
Gabrieleños, after the name of the Mission under whose control they worked during the mission period in California. Currently there are 1,700 people self-identifying as members of the
Tongva or Gabrieleño tribe. The
Mexican land grant for
Rancho Santa Anita was issued to
Perfecto Hugo Reid and his Tongva wife, Victoria Bartolomea Comicrabit, in 1845. It was named after a family relation, Anita Cota, on his wife's side. Reid documented the Gabrieleño Native Americans in a series of letters written in 1852, and served as a delegate to the
1849 California Constitutional Convention. In 1847, Reid sold Rancho Santa Anita to his
Rancho Azusa neighbor, Henry Dalton.
Lucky Baldwin The rancho changed owners several times before being acquired by Gold Rush immigrant, businessman, and major regional land owner
Elias Jackson "Lucky" Baldwin in 1875. Baldwin purchased of Rancho Santa Anita for $200,000. Upon seeing the area, he gasped "By Gads! This is paradise!" Upon buying the land, Baldwin chose to make the area his home and immediately started erecting buildings and cultivating the land for farming, orchards, and ranches. The residence was in the Italian
Renaissance Revival style, with murals by
Maynard Dixon. The estate had a significant
Greek Revival-style colonnaded "Parthenon" bathhouse/gymnasium beside a large pool, an apiary and aviaries, kennels and stables, tennis courts and pergolas, and preserved the native
oak woodlands. The school owner's efforts to develop the property into a village of homes with the old mansion as its centerpiece were rejected by the city. The city was on historic
U.S. Route 66, present-day
Colorado Boulevard, with businesses serving travelers on it.
Thoroughbred horse racing had flourished briefly under Lucky Baldwin, who founded a racetrack adjacent to the present site, until it was outlawed by the state of California in 1909. It returned to Arcadia when racing was legalized again, with the opening of
Santa Anita Park in December 1934. Architect
Gordon Kaufmann designed its various buildings in a combination of
Colonial Revival and
Streamline Moderne styles.
Santa Anita Assembly Center citizens arrive in Arcadia, relocated to the Santa Anita Assembly Center. racetrack The Santa Anita Assembly Center site is
California Historical Landmark #934. In 1942 during
World War II, the racetrack grounds were used as a processing and holding site for
Japanese Americans who had been removed from their homes and communities for forced relocation and
internment under President Franklin Roosevelt's
Executive Order 9066. The Civilian Assembly Center at the racetrack became the largest and longest operating one of the eighteen, holding citizens until the
Relocation Center camps were completed in interior areas of California and other states. More than 18,000 persons resided at the racetrack in primitive conditions. Four hundred temporary tarpaper barracks were constructed on the racetrack grounds to house many of the detainees, where they lived three families per unit. 8,500 detainees lived in converted horse stalls. The Assembly Center held people from late March through the end of October 1942, when the internees were relocated inland to
permanent internment camps at
Manzanar and
Tule Lake in California, and eight others in Western states and Arkansas. In November 1942 the center was turned over to the
United States Army Ordnance Corps for training purposes and was officially renamed
Camp Santa Anita. By the 2020 census, Asians consisted of 64.56% of the population. ==Geography==
