California is a state in the Western United States. It borders Oregon to the north, Nevada and Arizona to the east, the Mexican state of Baja California to the south; and has a coastline along the Pacific Ocean to the west. With over 39.5 million residents across a total area of approximately 163,696 square miles (423,970 km2), it is the most populous and the third-largest U.S. state by area.

Sacramento is the state's capital, while Los Angeles is the most populous city in the state and the second most populous city in the country (after New York City).

History

Tikhanov - Balthazar Inhabitant of Northern California (1818)
Balthazar, Inhabitant of Northern California, painting by Mikhail Tikhanov.

The Indigenous peoples of California included more than 70 distinct groups of Native Americans.

In the past, the area that was called "California" was not just today's California. This area covered the Mexican lands south of it, as well as Nevada, Utah, and parts of Arizona and Wyoming. The Spanish called the part of the land that later became part of the United States Alta California (Upper California) when it was split from what became Baja California (Lower California). In these early times, the borders of the Sea of Cortez and the Pacific coast were not well known, so the old maps wrongly showed California to be an island.

The first European who visited parts of the coast, Juan Rodriguez Cabrillo, came from Portugal in 1542. The first European who saw the entire coast was Sir Francis Drake, in 1579, and he decided that the British owned it. But starting in the late 1700s, Spanish religious leaders of the Roman Catholic Church ("missionaries") got large gifts of land in the area north of Baja California, from the Spanish king and queen. These religious people set up small towns and villages, the famous California Missions. When Mexico was no longer controlled by Spain, the Mexican government took over the villages, and they soon were depopulated.

In 1846, after the Mexican-American War broke out, some Americans in California hoped to create a California Republic. These men flew a "Bear flag" that had a golden bear with a star on it. This Republic ended suddenly, however, when Commodore John D. Sloat of the United States Navy sailed into San Francisco Bay. He said that California was now part of the United States. After the war with Mexico ended, California was split between the two countries. The Mexican portion became the Mexican states of Baja California Norte (north) and Baja California Sur (south). ("Baja" means "lower" in Spanish.) The western part of the part given to the United States became today's state of California.

In 1848, there were about 4,000 Spanish-speaking people in today's California on the American side. In 1849, gold was suddenly found and the population of the area went up very fast as the Gold Rush took hold. In 1850, California became a state in the Union (the United States).

During the American Civil War (1861-1865), many people in California, especially in the southern part of California, thought the South was right. Some people in Southern California even wanted Southern California to leave the rest of the state and join the Confederate States of America. However, this did not happen. California joined the war too and helped the North (the Union) and sent many troops east to fight the Confederacy.

At first, travel between the far west and the east coast of the United States was dangerous and took a lot of time. Going by land was very difficult, because there were no roads and no trains, and many Native Americans were attacking American people heading West in wagons. The only other way was to travel by boat around the Cape Horn, at the southern end of South America. This took months, since the trip was thousands of miles long and the Panama Canal had not yet been built either. But in 1869, the connection got better quickly, because the first railroad across the continent was finished. Meanwhile, more people in California were learning that the land there was very good to grow fruit and other crops. Oranges were grown in many parts of California. This was the beginning of the huge farming business that California has today.

Migration to California accelerated during the early 20th century with the completion of major transcontinental highways like the Lincoln Highway and Route 66. In the period from 1900 to 1965, the population grew from fewer than one million to become the most populous state in the Union. In 1940, the Census Bureau reported California's population as 6.0% Hispanic, 2.4% Asian, and 89.5% non-Hispanic white.

Attracted to the mild Mediterranean climate, cheap land, and the state's wide variety of geography, filmmakers established the studio system in Hollywood in the 1920s. California manufactured 8.7 percent of total United States military armaments produced during World War II, ranking third (behind New York and Michigan) among the 48 states.

After World War II, California's economy greatly expanded due to strong aerospace and defense industries, whose size decreased following the end of the Cold War. Stanford University and its Dean of Engineering Frederick Terman began encouraging faculty and graduates to stay in California instead of leaving the state, and develop a high-tech region in the area now known as Silicon Valley. As a result of these efforts, California is regarded as a world center of the entertainment and music industries, of technology, engineering, and the aerospace industry, and as the United States center of agricultural production.

During the 20th century, two great disasters happened in California. The 1906 San Francisco earthquake and 1928 St. Francis Dam flood remain the deadliest in U.S history.

California is often geographically divided into two regions, Southern California and Northern California.

In the middle of the state lies the California Central Valley, bounded by the Sierra Nevada in the east, the coastal mountain ranges in the west, the Cascade Range to the north and by the Tehachapi Mountains in the south. The Central Valley is California's productive agricultural heartland.

Divided in two by the Sacramento-San Joaquin River Delta, the northern portion, the Sacramento Valley serves as the watershed of the Sacramento River, while the southern portion, the San Joaquin Valley is the watershed for the San Joaquin River. Both valleys derive their names from the rivers that flow through them. With dredging, the Sacramento and the San Joaquin Rivers have remained deep enough for several inland cities to be seaports.

The Sacramento-San Joaquin River Delta is a critical water supply hub for the state. Water is diverted from the delta and through an extensive network of pumps and canals that traverse nearly the length of the state, to the Central Valley and the State Water Projects and other needs. Water from the Delta provides drinking water for nearly 23 million people, almost two-thirds of the state's population as well as water for farmers on the west side of the San Joaquin Valley.

The Channel Islands are located off the Southern coast.

The Sierra Nevada (Spanish for "snowy range") includes the highest peak in the contiguous 48 states, Mount Whitney, at 14,505 feet (4,421 m). The range embraces Yosemite Valley, famous for its glacially carved domes, and Sequoia National Park, home to the giant sequoia trees, the largest living organisms on Earth, and the deep freshwater lake, Lake Tahoe, the largest lake in the state by volume.

To the east of the Sierra Nevada are Owens Valley and Mono Lake, an essential migratory bird habitat. In the western part of the state is Clear Lake, the largest freshwater lake by area entirely in California. Though Lake Tahoe is larger, it is divided by the California/Nevada border. The Sierra Nevada falls to Arctic temperatures in winter and has several dozen small glaciers, including Palisade Glacier, the southernmost glacier in the United States.

About 45 percent of the state's total surface area is covered by forests, and California's diversity of pine species is unmatched by any other state. Many of the trees in the California White Mountains are the oldest in the world; an individual bristlecone pine is over 5,000 years old.

In the south is a large inland salt lake, the Salton Sea. The south-central desert is called the Mojave; to the northeast of the Mojave lies Death Valley, which contains the lowest and hottest place in North America, the Badwater Basin at −279 feet (−85 m). The horizontal distance from the bottom of Death Valley to the top of Mount Whitney is less than 90 miles (140 km). Indeed, almost all of southeastern California is arid, hot desert, with routine extreme high temperatures during the summer. The southeastern border of California with Arizona is entirely formed by the Colorado River, from which the southern part of the state gets about half of its water.

California contains both the highest point (Mount Whitney) and the lowest point (Death Valley) in the contiguous United States.

A majority of California's cities are located in either the San Francisco Bay Area or the Sacramento metropolitan area in Northern California; or the Los Angeles area, the Riverside-San Bernardino-Inland Empire, or the San Diego metropolitan area in Southern California. The Los Angeles Area, the Bay Area, and the San Diego metropolitan area are among several major metropolitan areas along the California coast.

As part of the Ring of Fire, California is subject to tsunamis, floods, droughts, Santa Ana winds, wildfires, landslides on steep terrain, and has several volcanoes. It has many earthquakes due to several faults running through the state, in particular the San Andreas Fault. About 37,000 earthquakes are recorded each year, but most are too small to be felt.

Climate

Although most of the state has a Mediterranean climate, due to the state's large size, the climate ranges from subarctic to subtropical.

The cool California Current offshore often creates summer fog near the coast. Farther inland, there are colder winters and hotter summers.

Northern parts of the state have more rain than the south.

California's mountains produce rain shadows on the eastern side, creating extensive deserts.

Ecology

California is one of the richest and most diverse parts of the world, and includes some of the most endangered ecological communities. California is part of the Nearctic ecozone and spans a number of terrestrial ecoregions.

California's large number of endemic species includes 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 largest trees, the tallest trees, and the oldest trees. California's native grasses are perennial plants. 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.

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, madrona, broad-leaved maple, and Douglas-fir also grow here.

Forest floors are covered with 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 tiger and leopard lilies.

The high elevations of the Canadian zone allow the Jeffrey pine, red fir, and lodgepole pine to thrive.

Common plants that have been introduced to the state include the eucalyptus, acacia, pepper tree, geranium, and Scotch broom.

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 sidewinder viper, desert tortoise, and horned toad. The upper Sonoran zone boasts mammals such as the antelope, brown-footed woodrat, and ring-tailed cat. Birds unique to this zone are the California thrasher, bushtit, and California condor.

In the transition zone, there are Colombian black-tailed deer, 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 water puppy and 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 blue-fronted jay, Sierra chickadee. Sierra hermit thrush, water ouzel, and Townsend's solitaire. Principal mammals found in this region include the Sierra coney, white-tailed jackrabbit, and the bighorn sheep. 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, golden, and cutthroat. Migratory species of salmon are common as well. Deep-sea life forms include 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.

Rivers

The vast majority of rivers in California are dammed as part of two massive water projects: the Central Valley Project, providing water to the agricultural central valley, the California State Water Project diverting water from northern to southern California.

The two most prominent rivers within California are the Sacramento River and the San Joaquin River.

According to the United States Census Bureau in 2022 the population self-identified as (alone or in combination): 56.5% White (including Hispanic Whites), 33.7% non-Hispanic white, 18.1% Asian, 7.3% Black or African American, 3.2% Native American and Alaska Native, 0.9% Native Hawaiian or Pacific Islander, and 34.3% some other race. These numbers add up to more than 100% because respondents can select multiple racial identities. 19% of Californians identified as two or more races in 2022, although excluding respondents who selected "some other race", only 5% identified as two or more races.

Hispanics are the largest single ethnic group in California. Non-Hispanic whites constituted 36.8% of the state's population. Californios are the Hispanic residents native to California, who make up the Spanish-speaking community that has existed in California since 1542, of varying Mexican American/Chicano, Criollo Spaniard, and Mestizo origin. However, they make up only a small part of California's Hispanic population today, estimated at 500,000. California has the largest Mexican, Salvadoran, and Guatemalan population, together making up over 90% of the state's Latino population.

English serves as California's de jure and de facto official language. Spanish is the most commonly spoken language in California, behind English, spoken by 28.18% (10,434,308) of the population (in 2021).

California has historically been one of the most linguistically diverse areas in the world, with more than 70 indigenous languages derived from 64 root languages in six language families. A survey conducted between 2007 and 2009 identified 23 different indigenous languages among California farmworkers. All of California's indigenous languages are endangered, although there are now efforts toward language revitalization. California has the highest concentration nationwide of Chinese, Vietnamese and Punjabi speakers.

The largest religious denominations by number of adherents as a percentage of California's population in 2014 were the Catholic Church with 28 percent, Evangelical Protestants with 20 percent, and Mainline Protestants with 10 percent. Together, all kinds of Protestants accounted for 32 percent. Those unaffiliated with any religion represented 27 percent of the population. The breakdown of other religions is 1% Muslim, 2% Hindu and 2% Buddhist.

Economy

The combined Port of Los Angeles-Port of Long Beach is the largest port in the U.S. by import volume and one of the busiest ports in the world.

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.

California's biggest trade partner is Mexico. In 2008, California exported $144 billion worth of goods, up from $134 billion in 2007 and $127 billion in 2006. Vehicles, computers and electronic products are California's top export, accounting for 42 percent of all the state's exports in 2008; over 50 car companies operate in California, such as Tesla and Mazda.

Agriculture

Agriculture is an important sector in California's economy. In 2011, the three largest California agricultural products by value were milk and cream, shelled almonds, and grapes. The agriculture sector accounts for two percent of the state's GDP and employs around three percent of its total workforce.

Government

The state's capital is Sacramento.

California is organized into three branches of government – the executive branch consisting of the Governor and the other independently elected constitutional officers; the legislative branch consisting of the Assembly and Senate; and the judicial branch consisting of the Supreme Court of California and lower courts.

Infrastructure

Energy

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.

As a result of the state's strong environmental movement, California has some of the most aggressive renewable energy goals in the United States. Currently, several solar power plants such as the Solar Energy Generating Systems facility are located in the Mojave Desert. California's wind farms include Altamont Pass, San Gorgonio Pass, and Tehachapi Pass. The Tehachapi area is also where the Tehachapi Energy Storage Project is located. Several dams across the state provide hydro-electric power. It would be possible to convert the total supply to 100% renewable energy, including heating, cooling and mobility, by 2050.

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.

California is also home to two major nuclear power plants: Diablo Canyon and San Onofre, the latter having been shut down in 2013. More than 1,700 tons of radioactive waste are stored at San Onofre, which sits in an area where there is a record of past tsunamis. Voters banned the approval of new nuclear power plants since the late 1970s because of concerns over radioactive waste disposal. In addition, several cities such as Oakland, Berkeley and Davis have declared themselves as nuclear-free zones.

Transportation

California's vast terrain is connected by an extensive system of [[Controlled-access highway|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. 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 state has been a pioneer in road construction. One of the state's more visible landmarks, the Golden Gate Bridge, was the longest suspension bridge main span in the world at 4,200 feet (1,300 m) 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 76 feet (23 m) wide by 58 feet (18 m) high. The Arroyo Seco Parkway, connecting Los Angeles and 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), the 4th busiest airport in the world in 2018, and San Francisco International Airport (SFO), the 25th busiest airport in the world in 2018, are major hubs for trans-Pacific and transcontinental traffic. There are about a dozen important commercial airports and many more general aviation airports throughout the state.

California also has several important seaports.
