Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America and contained the highest Native American population density north of what is now Mexico. European exploration in the 16th and 17th centuries led to the colonization of California by the Spanish Empire. In 1804, it was included in

Etymology

The Spaniards gave the name to the peninsula of Baja California and to Alta California, the latter region becoming the present-day state of California. The name 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. This work was the fifth in a popular Spanish chivalric romance series that began with ''

History


First inhabitants

Settled by successive waves of arrivals during at least the last 13,000 years, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. Various estimates of the native population have ranged from 100,000 to 300,000. The indigenous peoples of California included more than 70 distinct ethnic groups, inhabiting environments from mountains and deserts to islands and redwood forests. These groups were also diverse in their political organization, with bands, tribes, villages, and on the resource-rich coasts, large

. After failing to obtain justice against squatters on his land from the Mexican courts, he determined that California should become part of the United States. Marsh conducted a letter-writing campaign espousing the California climate, the soil, and other reasons to settle there, as well as the best route to follow, which became known as "Marsh's route". His letters were read, reread, passed around, and printed in newspapers throughout the country, and started the first wagon trains rolling to California. He invited immigrants to stay on his ranch until they could get settled, and assisted in their obtaining passports. After ushering in the period of organized emigration to California, Marsh became involved in a military battle between the much-hated Mexican general,

Marsh had been forced against his will to join Micheltorena's army. Ignoring his superiors, during the battle, he signaled the other side for a parley. There were many settlers from the United States fighting on both sides. He convinced these men that they had no reason to be fighting each other. As a result of Marsh's actions, they abandoned the fight, Micheltorena was defeated, and California-born Pio Pico was returned to the governorship. This paved the way to California's ultimate acquisition by the United States.


U.S. Conquest and the California Republic

In 1846, a group of American settlers in and around Sonoma rebelled against Mexican rule during the

Ide, who played a pivotal role during the Bear Flag Revolt. This revolt by American settlers served as a prelude to the later American military invasion of California and was closely coordinated with nearby American military commanders. The California Republic was short-lived; the same year marked the outbreak of the Mexican–American War (1846–48). Commodore John D. Sloat of the

In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both 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 capital has been located in Sacramento since 1854 with only a short break in 1862 when legislative sessions were held in San Francisco due to flooding in Sacramento. Once the state's Constitutional Convention had finalized its state constitution, it applied to the U.S. Congress for admission to statehood.

(1861–1865), California sent gold shipments eastward to Washington in support of the Union. However, due to the existence of a large contingent of pro-South sympathizers within the state, the state was not able to muster any full military regiments to send eastwards to officially serve in the Union war effort. Still, several smaller military units within the Union army were unofficially associated with the state of California, such as the "California 100 Company", due to a majority of their members being from California. At 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

was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state was extremely well suited to fruit cultivation and agriculture in general. 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 the state as part of the

California Genocide

Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which the indigenous people of California had not yet developed a natural immunity. Under its new American administration, California's harsh governmental policies towards its own indigenous people did not improve. As in other American states, many of the native inhabitants were soon forcibly removed from their lands by incoming American settlers such as miners, ranchers, and farmers. Although California had entered the American union as a free state, the "loitering or orphaned Indians" were de facto enslaved by their new Anglo-American masters under the 1853 '' Act for the Government and Protection of Indians''. There were also massacres in which hundreds of indigenous people were killed. Between 1850 and 1860, the California state government paid around 1.5million dollars (some 250,000 of which was reimbursed by the federal government) to hire militias whose purpose was to protect settlers from the indigenous populations. In later decades, the native population was placed in reservations and rancherias, which were often small and isolated and without enough natural resources or funding from the government to sustain the populations living on them. As a result, the rise of California was a calamity for the native inhabitants. Several scholars and Native American activists, including Benjamin Madley and Ed Castillo, have described the actions of the California government as a genocide.


1900–present

In the twentieth century, thousands of Japanese people migrated to the US and California specifically to attempt to purchase and own land in the state. However, the state in 1913 passed the Alien Land Act, excluding Asian immigrants from owning land. During World War II, Japanese Americans in California were interned in concentration camps such as at Tule Lake and Manzanar. In 2020, California officially apologized for this internment. Migration to California accelerated during the early 20th century with the completion of major transcontinental highways like the

Ecology

California is one of the ecologically richest and most diverse parts of the world, and includes some of the most endangered ecological communities. California is part of the Nearctic realm and spans a number of terrestrial ecoregions. California's large number of endemic (ecology), endemic species includes Relict (biology), relict species, which have died out elsewhere, such as the Catalina ironwood (''Lyonothamnus floribundus''). Many other endemics originated through differentiation or adaptive radiation, whereby multiple species develop from a common ancestor to take advantage of diverse ecological conditions such as the California lilac (''Ceanothus''). Many California endemics have become endangered, as urbanization, logging, overgrazing, and the introduction of exotic species have encroached on their habitat.


Flora and fauna

California boasts several superlatives in its collection of flora: the giant sequoia, largest trees, the coast redwood, tallest trees, and the pinus longaeva, oldest trees. California's native grasses are perennial plants, and there are close to hundred succulent species native to the state. After European contact, these were generally replaced by invasive species of European annual grasses; and, in modern times, California's hills turn a characteristic golden-brown in summer. Because California has the greatest diversity of climate and terrain, the state has six life zones which are the lower Sonoran Desert; upper Sonoran (foothill regions and some coastal lands), transition (coastal areas and moist northeastern counties); and the Canadian, Hudsonian, and Arctic Zones, comprising the state's highest elevations. Plant life in the dry climate of the lower Sonoran zone contains a diversity of native cactus, mesquite, and paloverde. The Yucca brevifolia, Joshua tree is found in the Mojave Desert. Flowering plants include the dwarf desert poppy and a variety of aster (genus), asters. Fremont cottonwood and valley oak thrive in the Central Valley. The upper Sonoran zone includes the chaparral belt, characterized by forests of small shrubs, stunted trees, and herbaceous plants. ''Nemophila'', Lamiaceae, mint, ''Phacelia'', ''viola (plant), Viola'', and the California poppy (''Eschscholzia californica'', the state flower) also flourish in this zone, along with the lupine, more species of which occur here than anywhere else in the world. The transition zone includes most of California's forests with the redwood (''Sequoia sempervirens'') and the "big tree" or giant sequoia (''Sequoiadendron giganteum''), among the oldest living things on earth (some are said to have lived at least 4,000 years). Tanbark oak, California laurel, sugar pine, Arbutus, madrona, Acer macrophyllum, broad-leaved maple, and Douglas-fir also grow here. Forest floors are covered with Polystichum, swordfern, alumnroot, barrenwort, and trillium, and there are thickets of huckleberry, azalea, elder, and wild currant. Characteristic wild flowers include varieties of mariposa, tulip, and Lilium columbianum, tiger and Lilium pardalinum, leopard lilies. The high elevations of the Canadian zone allow the Jeffrey pine, red fir, and lodgepole pine to thrive. Brushy areas are abundant with dwarf manzanita and ceanothus; the unique Calvatia sculpta, Sierra puffball is also found here. Right below the timberline, in the Hudsonian zone, the whitebark, foxtail, and silver pines grow. At about , begins the Arctic zone, a treeless region whose flora include a number of wildflowers, including Primula suffrutescens, Sierra primrose, Aquilegia flavescens, yellow columbine, Ranunculus, alpine buttercup, and Dodecatheon alpinum, alpine shooting star. Common plants that have been introduced to the state include the eucalyptus, acacia, Schinus, pepper tree, geranium, and Scotch broom. The species that are federally classified as endangered are the Erysimum capitatum, Contra Costa wallflower, Oenothera deltoides subsp. howellii, Antioch Dunes evening primrose, Tuctoria mucronata, Solano grass, Delphinium variegatum, San Clemente Island larkspur, Cordylanthus maritimus, salt marsh bird's beak, Arabis blepharophylla, McDonald's rock-cress, and Dudleya traskiae, Santa Barbara Island liveforever. , 85 plant species were listed as threatened or endangered. In the deserts of the lower Sonoran zone, the mammals include the jackrabbit, kangaroo rat, squirrel, and opossum. Common birds include the owl, roadrunner, cactus wren, and various species of hawk. The area's reptilian life include the Crotalus cerastes, sidewinder viper, desert tortoise, and horned toad. The upper Sonoran zone boasts mammals such as the Pronghorn, antelope, Dusky-footed woodrat, brown-footed woodrat, and ring-tailed cat. Birds unique to this zone are the California thrasher, Psaltriparus minimus, bushtit, and California condor. In the transition zone, there are Colombian black-tailed deer, American black bear, black bears, gray foxes, cougars, bobcats, and Roosevelt elk. Reptiles such as the garter snakes and rattlesnakes inhabit the zone. In addition, amphibians such as the Proteidae, water puppy and Batrachoseps attenuatus, redwood salamander are common too. Birds such as the kingfisher, chickadee, towhee, and hummingbird thrive here as well. The Canadian zone mammals include the mountain weasel, snowshoe hare, and several species of chipmunks. Conspicuous birds include the Steller's jay, blue-fronted jay, mountain chickadee, hermit thrush, American dipper, and Townsend's solitaire. As one ascends into the Hudsonian zone, birds become scarcer. While the gray-crowned rosy finch is the only bird native to the high Arctic region, other bird species such as Anna's hummingbird and Clark's nutcracker. Principal mammals found in this region include the Sierra coney, white-tailed jackrabbit, and the bighorn sheep. , the bighorn sheep was listed as endangered by the U.S. Fish and Wildlife Service. The fauna found throughout several zones are the mule deer, coyote, mountain lion, northern flicker, and several species of hawk and sparrow. Aquatic life in California thrives, from the state's mountain lakes and streams to the rocky Pacific coastline. Numerous trout species are found, among them Rainbow trout, rainbow, Golden trout, golden, and Cutthroat trout, cutthroat. Migratory species of salmon are common as well. Deep-sea life forms include White seabass, sea bass, yellowfin tuna, barracuda, and several types of whale. Native to the cliffs of northern California are seals, sea lions, and many types of shorebirds, including migratory species. , 118 California animals were on the federal endangered list; 181 plants were listed as endangered or threatened. Endangered animals include the Vulpes macrotis, San Joaquin kitfox, Aplodontia rufa nigra, Point Arena mountain beaver, Pacific pocket mouse, salt marsh harvest mouse, Morro Bay kangaroo rat (and five other species of kangaroo rat), California vole#Subspecies, Amargosa vole, California least tern, California condor, loggerhead shrike, Bell's sparrow, San Clemente sage sparrow, San Francisco garter snake, five species of salamander, three species of chub, and two species of pupfish. Eleven butterflies are also endangered and two that are threatened are on the federal list. Among threatened animals are the coastal California gnatcatcher, Paiute cutthroat trout, Sea otter#Subspecies, southern sea otter, and northern spotted owl. California has a total of of National Wildlife Refuges. , 123 California animals were listed as either endangered or threatened on the US Fish & Wildlife Service, federal list. Also, , 178 species of California plants were listed either as endangered or threatened on this federal list.

The estimated population as of 2022 is 39.22 million. For over a century (1900–2020), California experienced an explosion in population growth, adding an average of more than 300,000 people per year. California's rate of growth began to slow by the 1990s, although it continued to experience population growth in the first two decades of the 21st century. The state experienced population declines in 2020 and 2021, attributable to declining birth rates, COVID-19 pandemic deaths, and less internal migration from other states to California. The Greater Los Angeles Area is the 2nd-largest metropolitan area in the United States, after the New York metropolitan area, while Los Angeles, with nearly half the population of New York City, is the second-largest city in the United States. Conversely, San Francisco, with nearly one-quarter the population density of Manhattan, is the most densely populated city in California and one of the most densely populated cities in the United States. Also, Los Angeles County has held the title of most populous United States county for decades, and it alone is more populous than 42 U.S. states. Including Los Angeles, four of the List of United States cities by population, top 20 most populous cities in the U.S. are in California: Los Angeles (2nd), San Diego (8th), San Jose (10th), and San Francisco (17th).

, California-born residents make up the majority of the state's population. Along with the rest of the United States, California's immigration pattern has also shifted over the course of the late 2000s to early 2010s. Immigration from Latin American countries has dropped significantly with most immigrants now coming from Asia. In total for 2011, there were 277,304 immigrants. Fifty-seven percent came from Asian countries versus 22% from Latin American countries. Net immigration from Mexico, previously the most common country of origin for new immigrants, has dropped to zero / less than zero since more Mexican nationals are departing for their home country than immigrating. The state's population of undocumented immigrants has been shrinking in recent years, due to increased enforcement and decreased job opportunities for lower-skilled workers. The number of migrants arrested attempting to cross the Mexican border in the Southwest decreased from a high of 1.1million in 2005 to 367,000 in 2011.California's Illegal Immigrant Shortage

Los Angeles will host the 2028 Summer Olympics, marking the fourth time that California will have hosted the Olympic Games. Multiple games during the 1994 FIFA World Cup took place in California, with the Rose Bowl Stadium, Rose Bowl hosting eight matches (including the 1994 FIFA World Cup Final, final), while Stanford Stadium hosted six matches.


Education

California has the most school students in the country, with over 6.2 million in the 2005–06 school year, giving California more students in school than 36 states have in total population and one of the highest projected enrollments in the country.Public Secondary education in the United States, secondary education consists of High school (North America), high schools that teach elective courses in trades, languages, and liberal arts with tracks for gifted, college-bound and industrial arts students. California's public educational system is supported by a California Proposition 98 (1988), unique constitutional amendment that requires a minimum annual funding level for grades K–12 and community colleges that grows with the economy and student enrollment figures. In 2016, California's K–12 public school per-pupil spending was ranked 22nd in the nation ($11,500 per student vs. $11,800 for the U.S. average). For 2012, California's K–12 public schools ranked 48th in the number of employees per student, at 0.102 (the U.S. average was 0.137), while paying the 7th most per employee, $49,000 (the U.S. average was $39,000). A 2007 study concluded that California's public school system was "broken" in that it suffered from overregulation.


Higher education

California public postsecondary education is organized into three separate systems: * The state's Public university, public research university State university system, system is the University of California (UC). As of fall 2011, the University of California had a combined student body of 234,464 students. There are ten UC campuses. Nine are general campuses offering both undergraduate and graduate programs which culminate in the award of bachelor's degrees, master's degrees, and doctorates. There is one specialized campus, UC San Francisco, which is entirely dedicated to graduate education in health care, and is home to the UCSF Medical Center, the highest ranked hospital in California. The system was originally intended to accept the top one-eighth of California high school students, but several of the campuses have become even more selective.Powell, Farran. "California Students Face Competition for College Options". ''U.S. News & World Report''. N.p., February 6, 2017. Web. May 7, 2017. The UC system historically held exclusive authority to award the doctorate, but this has since changed and CSU now has limited statutory authorization to award a handful of types of doctoral degrees independently of UC. * The California State University (CSU) system has almost 430,000 students. The CSU (which takes the definite article in its abbreviated form, while UC does not) was originally intended to accept the top one-third of California high school students, but several of the campuses have become much more selective. The CSU was originally authorized to award only bachelor's and master's degrees, and could award the doctorate only as part of joint programs with UC or private universities. Since then, CSU has been granted the authority to independently award several doctoral degrees (in specific academic fields that do not intrude upon UC's traditional jurisdiction). * The California Community Colleges system provides lower-division coursework culminating in the associate degree, as well as basic skills and workforce training culminating in various kinds of certificates. (Fifteen California community colleges now award four-year bachelor's degrees in disciplines which are in high demand in their geographical area.) It is the largest network of higher education in the U.S., composed of 112 colleges serving a student population of over 2.6million. California is also home to such notable private universities as Stanford University, the California Institute of Technology (Caltech), the University of Southern California, the Claremont Colleges, Santa Clara University, Loyola Marymount University, the University of San Diego, the University of San Francisco, Chapman University, Pepperdine University, Occidental College, and University of the Pacific (United States), University of the Pacific, among numerous other private colleges and universities, including many religious and special-purpose institutions. California has a particularly high density of arts colleges, including the California College of the Arts, California Institute of the Arts, San Francisco Art Institute, Art Center College of Design, and Academy of Art University, among others.


Economy

California's economy ranks among the largest in the world. , the gross state product (GSP) was $3.31000000000000 (number), trillion ($85,500 per capita), the largest in the United States. California is responsible for one seventh of the nation's gross domestic product (GDP). , California's nominal GDP is larger than all but four countries (the Economy of the United States, United States, Economy of China, China, Economy of Japan, Japan, and Economy of Germany, Germany). In terms of purchasing power parity (PPP), it is larger than all but eight countries (the United States, China, Economy of India, India, Japan, Germany, Economy of Russia, Russia, Economy of Brazil, Brazil, and Economy of Indonesia, Indonesia). California's economy is larger than Economy of Africa, Africa and Economy of Australia, Australia and is almost as large as Economy of South America, South America. The state recorded total, non-farm employment of 16,677,800 among 966,224 employer establishments (). The five largest sectors of employment in California are trade, transportation, and utilities; government; professional and business services; education and health services; and leisure and hospitality. In output, the five largest sectors are financial services, followed by trade, transportation, and utilities; education and health services; government; and manufacturing. California has an California unemployment statistics, unemployment rate of 3.9% . California's economy is dependent on trade and international related commerce accounts for about one-quarter of the state's economy. In 2008, California exported $144billion worth of goods, up from $134billion in 2007 and $127billion in 2006. Computers and electronic products are California's top export, accounting for 42 percent of all the state's exports in 2008. Agriculture is an important sector in California's economy. Farming-related sales more than quadrupled over the past three decades, from $7.3billion in 1974 to nearly $31billion in 2004. This increase has occurred despite a 15 percent decline in acreage devoted to farming during the period, and water supply suffering from chronic instability. Factors contributing to the growth in sales-per-acre include more intensive use of active farmlands and technological improvements in crop production. In 2008, California's 81,500 farms and ranches generated $36.2billion products revenue. In 2011, that number grew to $43.5billion products revenue. The Agriculture sector accounts for two percent of the state's GDP and employs around three percent of its total workforce. According to the United States Department of Agriculture, USDA in 2011, the three largest California agricultural products by value were milk and cream, shelled almonds, and grapes.

State finances

State spending increased from $56billion in 1998 to $127billion in 2011. California has the third highest per capita spending on welfare among the states, as well as the highest spending on welfare at $6.67billion. In January 2011, California's total debt was at least $265billion. On June 27, 2013, Governor Jerry Brown signed a balanced budget (no deficit) for the state, its first in decades; however the state's debt remains at $132billion. With the passage of California Proposition 30 (2012), Proposition 30 in 2012 and 2016 California Proposition 55, Proposition 55 in 2016, California now levies a 13.3% maximum marginal income tax rate with ten tax brackets, ranging from 1% at the bottom tax bracket of $0 annual individual income to 13.3% for annual individual income over $1,000,000 (though the top brackets are only temporary until Proposition 55 expires at the end of 2030). While Proposition 30 also enacted a minimum sales taxes in the United States#California, state sales tax of 7.5%, this sales tax increase was not extended by Proposition 55 and reverted to a previous minimum state sales tax rate of 7.25% in 2017. Local governments can and do levy additional sales taxes in addition to this minimum rate. All real property is taxable annually; the ad valorem tax is based on the property's fair market value at the time of purchase or the value of new construction. Property tax increases are capped at 2% annually or the rate of inflation (whichever is lower), per California Proposition 13 (1978), Proposition 13.


Infrastructure


Energy

Because it is the most populous state in the United States, California is one of the country's largest users of energy. However, because of its high energy rates, conservation mandates, mild weather in the largest population centers and strong environmental movement, its ''per capita'' energy use is one of the smallest of any state in the United States. Due to the high electricity demand, California imports more electricity than any other state, primarily hydroelectric power from states in the Pacific Northwest (via Path 15 and Path 66) and coal- and natural gas-fired production from the desert Southwest via Path 46. The state's crude oil and natural gas deposits are located in the Central Valley and along the coast, including the large Midway-Sunset Oil Field. Natural gas-fired power plants typically account for more than one-half of state electricity generation. As a result of the state's strong environmental movement, California has some of the most aggressive renewable energy goals in the United States, with a target for California to obtain a third of its electricity from renewables by 2020. Currently, several solar power plants such as the Solar Energy Generating Systems facility are located in the Mojave Desert. Wind power in California, California's wind farms include Altamont Pass Wind Farm, Altamont Pass, San Gorgonio Pass Wind Farm, San Gorgonio Pass, and Tehachapi Pass Wind Farm, Tehachapi Pass. The Tehachapi area is also where the Tehachapi Energy Storage Project is located. Several dams across the state provide Hydroelectricity, hydro-electric power. It would be possible to convert the total supply to 100% renewable energy, including heating, cooling and mobility, by 2050. California is also home to two major nuclear power plants: Diablo Canyon Power Plant, Diablo Canyon and San Onofre Nuclear Generating Station, San Onofre, the latter having been shut down in 2013. More than 1,700tons of radioactive waste are stored at San Onofre, which sits in an area where there is a record of past

s. Voters banned the approval of new nuclear power plants since the late 1970s because of concerns over High-level radioactive waste management, radioactive waste disposal. In addition, several cities such as Oakland, Berkeley, California, Berkeley and Davis, California, Davis have declared themselves as nuclear-free zones.


Transportation

California's vast terrain is connected by an extensive system of controlled-access highways ('freeways'), limited-access roads ('expressways'), and highways. California is known for its car culture, giving California's cities a reputation for severe traffic congestion. Construction and maintenance of state roads and statewide transportation planning are primarily the responsibility of the California Department of Transportation, nicknamed "Caltrans". The rapidly growing population of the state is straining all of its transportation networks, and California has some of the worst roads in the United States. The Reason Foundation's 19th Annual Report on the Performance of State Highway Systems ranked California's highways the third-worst of any state, with Alaska second, and Rhode Island first. The state has been a pioneer in road construction. One of the state's more visible landmarks, the Golden Gate Bridge, was the List of longest suspension bridge spans, longest suspension bridge main span in the world at between 1937 (when it opened) and 1964. With its orange paint and panoramic views of the bay, this highway bridge is a popular tourist attraction and also accommodates pedestrians and bicyclists. The San Francisco–Oakland Bay Bridge (often abbreviated the "Bay Bridge"), completed in 1936, transports about 280,000 vehicles per day on two-decks. Its two sections meet at Yerba Buena Island through the world's largest diameter transportation bore tunnel, at wide by high. The Arroyo Seco Parkway, connecting Los Angeles and Pasadena, California, Pasadena, opened in 1940 as the first freeway in the Western United States. It was later extended south to the Four Level Interchange in downtown Los Angeles, regarded as the first stack interchange ever built. Los Angeles International Airport (LAX), World's busiest airports by passenger traffic, the 4th busiest airport in the world in 2018, and San Francisco International Airport (SFO), World's busiest airports by passenger traffic, the 25th busiest airport in the world in 2018, are major hubs for trans-Pacific and transcontinental traffic.
