9855-535: The deadliest in U.S. history. Although air pollution has been reduced, health problems associated with pollution continue. Brown haze known as " smog " has been substantially abated after federal and state restrictions on automobile exhaust. An energy crisis in 2001 led to rolling blackouts , soaring power rates, and the importation of electricity from neighboring states. Southern California Edison and Pacific Gas and Electric Company came under heavy criticism. Housing prices in urban areas continued to increase;

9990-556: The early 1960s modern residential development began to take place. When Simí was an agricultural community, there were ranch houses that dotted the Valley. Four distinct communities also were located in the Valley (see 'Four Communities of Simi Valley' section below) prior to modern residential development. Though 1957 and 1958 brought the first 'tract' housing developments when the Dennis and Ayhens, Wright Ranch and Valley Vista tracts were built,

Several scholars and Native American activists, including Benjamin Madley and Ed Castillo , have described the actions of the California government as a genocide , as well as the 40th governor of California Gavin Newsom . Benjamin Madley estimates that from 1846 to 1873, between 9,492 and 16,092 indigenous people were killed, including between 1,680 and 3,741 killed by

José de la Guerra y Noriega , a Captain of the Santa Barbara Presidio , who had begun to acquire large amounts of land in California to raise cattle, purchased Rancho Simí from the Pico family in 1842. After Jose de la Guerra death in 1858, the sons of Jose de la Guerra continued to operate the ranchos. The end of their prosperity came when several years of drought in

10935-410: The indigenous peoples developed complex forms of ecosystem management, including forest gardening to ensure the regular availability of food and medicinal plants . This was a form of sustainable agriculture . To mitigate destructive large wildfires from ravaging the natural environment, indigenous peoples developed a practice of controlled burning .

11475-468: The mainland in the early 19th century. John Peabody Harrington conducted fieldwork on all the above Chumashan languages, but obtained the least data on Island Chumash, Purisimeño, and Obispeño. There is no linguistic data on Cuyama, though ethnographic data suggests that it was likely Chumash (Interior Chumash). The languages are named after the local Franciscan Spanish missions in California where Chumashan speakers were relocated and aggregated between

Droughts and wildfires are an ongoing issue. California's economy

12690-642: The older names based on the local missions. Obispeño was the most divergent Chumashan language. The Central Chumash languages include Purisimeño, Ineseño, Barbareño and Ventureño. There was a dialect continuum across this area, but the form of the language spoken in the vicinity of each mission was distinct enough to qualify as a different language. There is very little documentation of Purisimeño. Ineseño, Barbareño and Ventureño each had several dialects, although documentation usually focused on just one. Island Chumash had different dialects on Santa Cruz Island and Santa Rosa Island , but all speakers were relocated to

12825-409: The oldest language families established in California, before the arrival of speakers of Penutian , Uto-Aztecan , and perhaps even Hokan languages . Chumashan, Yukian, and southern Baja languages are spoken in areas with long-established populations of a distinct physical type. The population in the core Chumashan area has been stable for the past 10,000 years. However, the attested range of Chumashan

12960-401: The origin and meaning of the word 'California, ' " and that all anyone knows is the name was added to a map by 1541 "presumably by a Spanish navigator." The name most likely derived from the mythical island of California in the fictional story of Queen Calafia , as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo . Queen Calafia's kingdom was said to be

The median cost of homes in Simi Valley was $ 704,200 with mortgages at a median of $ 3,047. Simi Valley's government uses the " council-manager " form of government. This means that

13230-474: The population increased significantly. Shortly after this sharp increase a precious stone money system arose, increasing the viability of the region by offsetting fluctuations in available resources relating to climate changes. The native people who inhabited Simi Valley spoke an interior dialect of the Chumash language, called Ventureño . Simi Valley's name is derived from the Chumash word Shimiyi, which refers to

13365-414: The population of San Francisco increased from 500 to 150,000. The seat of government for California under Spanish and later Mexican rule had been located in Monterey from 1777 until 1845.

While the mean temperature is at its lowest at 53.6 degrees (12.0 °C) in December, the mean temperature in July and August exceeds 76 degrees (24 °C). Simi Valley has been the victim of several natural disasters, including the flood of 1967, the storm of 1983, the 1988 lightning strike, as well as the 1994 Northridge earthquake and numerous wildfires. Simi Valley has

13770-585: The prominent Pico family of California . Rancho Simí was the earliest Spanish colonial land grant within Ventura and Santa Barbara Counties. The name derives from Shimiji, the name of the Chumash Native American village here before the Spanish. It was the largest Spanish or Mexican land grant given in Ventura County, and one of the largest given in California. The Simi Adobe-Strathearn House , later

13905-710: The pueblo of San Jose in 1777, making it the first civilian-established city in California. During this same period, sailors from the Russian Empire explored along the northern coast of California. In 1812, the Russian-American Company established a trading post and small fortification at Fort Ross on the North Coast . Fort Ross was primarily used to supply Russia's Alaskan colonies with food supplies. The settlement did not meet much success, failing to attract settlers or establish long term trade viability, and

14040-416: The races until the Indian race becomes extinct must be expected. While we cannot anticipate the result with but painful regret, the inevitable destiny of the race is beyond the power and wisdom of man to avert." As in other American states, indigenous peoples were forcibly removed from their lands by American settlers , like miners, ranchers, and farmers. Although California had entered the American union as

14175-644: The state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882 Chinese Exclusion Act . Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which

14310-460: The state on March 4, 2020, and remained in effect until Governor Gavin Newsom ended it in February 2023. A mandatory statewide stay-at-home order was issued on March 19, 2020, which was ended in January 2021. Cultural and language revitalization efforts among indigenous Californians have progressed among tribes as of 2022. Some land returns to indigenous stewardship have occurred. In 2022,

14445-515: The state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Middle Easterns, Chinese and other immigrants during the great California gold rush . By the time of California's application for statehood in 1850, the settler population of California had multiplied to 100,000. By 1854, more than 300,000 settlers had come. Between 1847 and 1870,

As a result of this, California is a world center of the entertainment and music industries, of technology, engineering, and the aerospace industry, and as the US center of agricultural production. Just before the Dot Com Bust , California had the fifth-largest economy in the world. In the mid and late twentieth century, race-related incidents occurred. Tensions between police and African Americans, combined with unemployment and poverty in inner cities, led to riots, such as

14715-557: The stringy, thread-like clouds that typify the region . The name could have originated from the strands of mist from coastal fog that move into the Oxnard Plain and wind their way up the Calleguas Creek and the Arroyo Las Posas into Simi Valley. The origin of the name was preserved because of the work of the anthropologist John P. Harrington , whose brother, Robert E. Harrington lived in Simi Valley. Robert Harrington later explained

14850-504: The ten southernmost counties, and Northern California , comprising the 48 northernmost counties. It is bordered by Oregon to the north, Nevada to the east and northeast, Arizona to the southeast, the Pacific Ocean to the west and shares an international border with the Mexican state of Baja California to the south (with which it makes up part of The Californias region of North America , alongside Baja California Sur ). In

14985-407: The time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the first transcontinental railroad was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state

15120-412: The town of Santa Susana was born. The Depot was moved in 1975 by Rancho Simi Recreation and Park District to its current location off of Kuehner. Community Center – In 1922 L.F.

By 1970 the population in Simi is reported by the census as 59,832. The pioneers arrived in the late 1860s – 1870s and ever since, this has been 'The Valley of Simi.' But, not all the communities in the valley were known as 'Simi.' There was the township of Simi (known as 'Simiopolis' for about

15525-489: The unpublished fieldnotes of linguist John Peabody Harrington . Especially well documented are Barbareño , Ineseño , and Ventureño . The last native speaker of a Chumashan language was Barbareño speaker Mary Yee , who died in 1965. Six Chumashan languages are attested , all now extinct. However, most of them are in the process of revitalization, with language programs and classes. Contemporary Chumash people now prefer to refer to their languages by native names rather than

Governor Pablo Vicente de Solá presided over

16605-486: Was ceded to the United States in 1848 after the Mexican–American War . The California gold rush started in 1848 and led to social and demographic changes, including depopulation of Indigenous tribes.

Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere. In the nineteenth century, a large number of migrants from China traveled to

16875-607: Was highly unstable, and in a reflection of this, from 1831 onwards, California also experienced a series of armed disputes, both internal and with the central Mexican government. During this tumultuous political period Juan Bautista Alvarado was able to secure the governorship during 1836–1842. The military action which first brought Alvarado to power had momentarily declared California to be an independent state, and had been aided by Anglo-American residents of California, including Isaac Graham . In 1840, one hundred of those residents who did not have passports were arrested, leading to

Before the 1960s, Simi Valley once boasted a strong community of Latino families, many of whom worked for white ranchers. However, the housing boom in the 1960s and 1970s attracted many white Americans leaving urban areas in Los Angeles and the San Fernando Valley . This turned Simi Valley into

Women were often responsible for weaving, harvesting, processing, and preparing food, while men for hunting and other forms of physical labor. Most societies also had roles for people whom the Spanish referred to as joyas , who they saw as "men who dressed as women". Joyas were responsible for death , burial , and mourning rituals , and they performed women's social roles. Indigenous societies had terms such as two-spirit to refer to them. The Chumash referred to them as 'aqi. The early Spanish settlers detested and sought to eliminate them. The first Europeans to explore

Technical analysis of the incident intended to support a lawsuit against the current landowner ( The Boeing Company ) asserts the incident caused the much greater release of radioactivity than the accident at Three Mile Island . Boeing's technical response concludes

Sloat of the United States Navy sailed into Monterey Bay in 1846 and began the U.S. military invasion of California , with Northern California capitulating in less than a month to the United States forces. In Southern California, Californios continued to resist American forces. Notable military engagements of
