California (English: California) is a State in the southwest of the United States, referred to as California, another name "Golden State" (Golden State). It borders the Pacific Ocean to the west, Oregon to the north, Nevada to the east, Arizona to the southeast, and Mexico to the south. California has 2,030 kilometers of coastline, with a total area of about 424,000 square kilometers. [3] As of 2024, the population is 38.88 million. California has 58 counties, with Sacramento as its capital. [2-4] California has a diverse population, including Hispanics, Asians and AfricAn-Americans. [3]
California's topography is diverse, with Mount Whitney and Death Valley representing the highest and lowest points in the lower 48 states. [2] The hydrological system of California is affected by terrain and climate. The southern desert area is dry and has little rain, while the northern coastal area has much rain and snow in winter. The overall climate is characterized by wet and rainy winter and dry summer. [3] European exploration in the 16th and 17th centuries began the Spanish colonization of California, and the area became part of the New Spanish Viceroyalty in 1804. After Mexican independence in 1821, California became a part of Mexico until it was ceded to the United States after the MexicAn-American War of 1848. California was admitted as the 31st state on September 9, 1850. [5-6]
As of 2022, California's gross state product reached $3.6 trillion, with a per capita GDP of $92,190. [7] California's characteristic industries include information technology industry, biotechnology industry, environmental protection industry, agriculture, aerospace industry, film and television entertainment industry. [3] It brings together many of the world's top companies, including Apple, Oracle, HP, Paramount, Fox, Warner Brothers, etc. And world-renowned universities, such as the University of California, California Conservatory of Music and so on.

Name evolution

broadcast
EDITOR
There are several versions of the origin of the name California, one of which is widely accepted that the name comes from a 16th-century Spanish chivalric novel, Esplendor de la California (meaning "California's glory"), "California" refers to a fictional island in the Indus River in Asia, a place filled with gold and precious stones. The name was first used geographically by Hernando de Alarcon, a Spanish explorer who explored the Gulf of California in 1542 and named it "California". [13]
In addition, there is also a suggestion that the name "California" may be derived from the Spanish words "caliente" (meaning "hot") and "fornalha" (meaning "stove" or "furnace"), which combined means "hot furnace", which may be related to the climatic characteristics of some parts of California. [13]

Historical evolution

EDITOR

Aboriginal period

About 20,000 years ago, the first humans in Asia migrated to California through the Bering Strait. In this land, the natural isolation of mountains and deserts has resulted in the formation of more than 500 Native American tribes, each of which has developed a distinct culture, including Pomo, Tolowa, Miwock, Maidu, Kato, Wentong, Kavila, Chemewewi, Chumash, Karoko, Mojave, Yokut, Paiute, and Modoc. These tribes usually exist as peaceful family clans and lack complex political structures. [5]
By the mid-18th century, when Spanish missionaries first arrived in California, there were an estimated 30,000 Native Americans, or 13 percent of the total Native population of North America at the time. In subsequent centuries, however, this population began to decline due to disease, forced labor by Spanish missions, and the activities of American settlers in the late 19th century. [5]

Spanish period

The first Europeans to explore the California coast were members of a Spanish maritime expedition led by Portuguese captain Juan Rodriguez Cabrillo in 1542. Commissioned by the Governor of New Spain, Antonio de Mendoza, to explore and look for trade opportunities, Cabrillo entered the Bay of Santiago on September 28, 1542, and went north at least as far as the island of SAN Miguel. Privateer and explorer Francis Drake explored and claimed an undefined portion of the California coast in 1579, landing north of San Francisco. In 1587, the first Asians, Filipino sailors, arrived in Moro Bay on Spanish ships. Sebastian Vizcaino explored and mapped the California coast for the New Spain party in 1602 and came ashore at Monterey. Despite field exploration of California in the 16th century, many European maps continued to label California as an island until the 18th century. [5-6]
The Portola Expedition of 1769-1770 was a key event in the Spanish colonization of California, leading to the establishment of several mission areas, forts, and villages. The military and civil elements of the expedition were led by Gaspar de Portola, while the religious elements were led by Junipero Serra. In 1769, they established the Mission and Fort at San Diego, the first religious and military settlement of the Spanish in California. In 1770, they established a fort and mission in Monterey Bay. After the Portola expedition, Spanish missionaries led by Serra began to establish 21 missions along El Camino Real, 16 of which were selected during the expedition. Many of California's major cities, including San Francisco, San Diego, Ventura, and Santa Barbara, grew out of these mission areas. [5-6]
Juan Bautista de Anza led an expedition deep into the interior and northern California in 1775-1776, selecting many sites for the establishment of missions, forts, and villages. Expedition member Gabriel Moraga named many of California's famous rivers, such as the Sacramento and SAN Joaquin Rivers. After the expedition, Jose Joaquin Moraga discovered the village of SAN Jose in 1777, becoming the first city in California founded by commoners. [5-6]
In 1776, Spain established the SAN Juan Capistrano Mission, the third mission in California. At the same time, Russian sailors also explored the northern coast of California and established the Roseburg Trading Post in 1812, primarily to supply grain to the Russian colony of Alaska, but the settlement was unsuccessful and abandoned in 1841. [5-6]

Mexican period

After the Mexican War of Independence in 1821, Mexico gained its independence from Spain. In 1822, California became a province of Mexico. Under Mexican rule, a ranching culture developed in the area, and Mexico's free trade policies facilitated trade between California and the United States and Great Britain. [5-6]
In 1826, hunter Jedediah Smith led the first American citizens into the region by land. By 1841, John Bidwell and John Bartleson led the first organized American settlers to settle in California. The influx of immigrants from the United States continued, and by the mid-1840s they outnumbered the native Mexican citizens. [5-6]

Seek independence

In 1846, American immigrants rebelled against Mexican rule and declared California an independent nation, an event known in history as the Bear Flag Rebellion. [5-6]
Unbeknownst to the leaders of what came to be known as the Bear Flag Rebellion, however, the United States had declared war on Mexico, and the rebels gave up their rule when U.S. Brigadier General John D. Slott captured Monterey and raised the American flag over the city. Within weeks of the beginning of the concept of independence, they declared their allegiance to the United States. [14]

Join the United States

In the mid-19th century, as relations between the United States and Mexico strained, American explorers and troops began to enter the California area. The expeditions of John Charles Fremont, as well as the actions of the United States Navy, increased the suspicion of the Mexican government and the local population about American intentions. During this period, the United States government showed an interest in territorial expansion, and war broke out with Mexico. [15]
A month after the Bear Flag Rebellion, American forces took control of California. In January 1847, California effectively surrendered to the United States. With the signing of the Treaty of Guadalupe Hidalgo on February 2, 1848, California was formally ceded to the United States. In the end, California was admitted to the Union as the 31st state on September 9, 1850, without an interim period of statehood. [5-6]

Gold rush and immigration

On January 24, 1848, James Marshall discovered gold in a sawmill built at Sutter's Mill in Coloma, California, a discovery that sparked the famous California Gold Rush. Most of the original gold miners were immigrants from outside the United States, including Mexico, Chile and China. After President James Polk had recognized the discovery the previous year, gold prospectors known as the "Forty-Nine" began pouring into California in 1849. [5]
In 1849 alone, more than 100,000 people moved to California from the United States and around the world, including Europe, Australia, New Zealand, and China. Some of them came in search of gold, while others opened bars and other businesses. Between 1847 and 1860, the state's population tripled to 308,000. The gold Rush dramatically changed the lives of Native Americans in California, who were nearly wiped out within a few years due to massive waves of immigration. Although most gold miners did not strike it rich, miners did mine a whopping 28,280,711 ounces of pure gold between 1850 and 1859. [5]
By the 1870s, nearly all of the 63,000 Chinese immigrants in the United States were living in California, and anti-Chinese sentiment was on the rise. The Chinese were involved in the construction of the transcontinental railroad in the 1860s, then turned to agricultural work in the early 1870s. This, combined with the economic downturn of the 1870s, prompted the passage of the Chinese Exclusion Act in 1882, which banned Chinese immigration until China became an ally of the United States in World War II. [5]
The passage of the Immigration and Naturalization Act of 1965 opened up the immigration policy of the United States, and people from all over the world began to flood into California, especially from Mexico, China, the Philippines, Central America, and India. The passage of this bill marked a major shift in U.S. immigration policy, bringing new demographics and cultural diversity to California. [5]

Secession crisis

In the mid-19th century, secessionist tendencies emerged within California, particularly among Spanish-speaking residents and pro-slavery Southern Californians who were unhappy with state tax and land laws and advocated for southern California's independence from California. In 1855, the California House of Representatives passed a partition plan that proposed dividing California into two new states: Colorado and Shasta. The reason behind this proposal was that California's large size was disproportionate to its representation in the United States Congress, and that the distance between the state capital and the southern region made governing difficult. [16]
Although the House of Representatives passed the split, the California Senate did not, as they considered it a lower priority than other more pressing political issues. In 1859, in recognition of the vast cultural and topographical differences, the California legislature approved the Biko Act, which planned to divide California into two parts along the 36th parallel, with the southern part forming the Colorado Territory and the northern part remaining California. The measure was supported by more than 75 percent of local voters. [16]
However, with the election of Abraham Lincoln in 1860 and the emergence of a secession crisis in the United States, Congress did not vote on California's secession proposal. Soon after, the Civil War broke out, a historic event that eventually led to the shelving of the California breakup proposal, and California maintained its status as a unified state and supported the Union during the war. [16]

20th century to present

On April 18, 1906, a large earthquake occurred off the coast of Northern California, with an estimated magnitude of 7.9 and a maximum Magali intensity of VII to IX. High-intensity tremors were felt from Eureka on the north coast to the Salinas Valley, an agricultural region in the southern San Francisco Bay Area. A devastating fire soon broke out in San Francisco and lasted for several days. More than 3,000 people died and more than 80% of the city was destroyed. [17]
Beginning in 1908, California's mild climate attracted many film studios from the East Coast to relocate there, and because Thomas Edison held numerous film patents and frequently forced film makers to shut down through legal action, California did not enforce these patent rules, which provided a more relaxed creative environment for film makers. As a result, Hollywood quickly rose to become the center of the American film industry, bringing huge economic profits and attracting a lot of talent and capital. [18]
In 1913, the California State government enacted the Alien Land Act, which prohibited Asian immigrants, including Japanese, from owning land. [19]
In 1939, Stanford University students William Hewllet and David Packard invented the audio oscillator. Their success led Stanford University to establish the Stanford Research Institute, which gave birth to other successful companies such as General Electric, Kodak and Lockheed. Silicon Valley was born. Apple, Microsoft, PlayStation and many other companies got their start here, propelling California's economic take-off. [18]
In 1960, the state of California adopted the California Higher Education Master Plan to develop an efficient public education system. [20]
In 1962, California surpassed New York as the most populous state. [21]
On January 7, 2019, in Sacramento, California, the United States, the new governor of California Gavin Newsom was sworn in as the 40th governor of California. [22]
On September 30, 2020, California Governor Gavin Newsom signed into law a bill making Chinese New Year a legal holiday in California. [23]

Physical geography

Location boundary

California is located in the southwest of the United States, between 32 degrees and 42 degrees north latitude, a total coastline of 2030 kilometers, the Pacific Ocean to the west, Oregon to the north, Nevada to the east, Arizona to the southeast, and Mexico to the south. It is 1,600 kilometers long from north to south and 413 kilometers wide from east to west. As of 2022, the entire state covers an area of 403,500 square kilometers [1] It is the third largest state in the United States (after Alaska and Texas). [3]

climate

California as a whole has a temperate climate, rainy and humid winter, the average temperature of 7℃-17℃; Summer is dry, sunny, average temperature 15℃-26℃; The average annual precipitation is only 357 mm. [26] The climatic conditions of the state are diverse, the southern desert area is more arid, and the northern coastal area has more rain and snow in winter. [2] The highest temperature ever recorded in California was 134°F(57°C) on July 10, 1913, which was also the highest temperature ever recorded on Earth. The lowest temperature was -45°F(-43°C) on January 20, 1937. [24]

geology

California's geological history spans a long period, with its oldest rocks dating back 1.8 billion years to the Proterozoic era, mostly in the SAN Gabriel Mountains, SAN Bernardino Mountains and the Mojave Desert. During the Paleozoic period, a shallow continental shelf was formed in eastern California, where a large amount of limestone was deposited, which is widely distributed in the Sierra Nevada, Klamath Mountains, and Eastern Transverse Mountains. During the Mesozoic Triassic, active subduction contributed to the beginning of the Nevada orogenesis, with the formation of large granite intrusions, increased dry land conditions, and the ocean retreated to the west. During the Jurassic period, this orogeny accelerated further, as deep sea basins were continuously filled with sediment, such as the great valley beds in the Coastal Mountains. During the Cenozoic, volcanic activity occurred in the California periphery, and Marine sedimentary rocks were widely deposited in the Central Valley, Transversal Mountains, and Coastal Mountains, forming deep sedimentary sequences in places such as the Los Angeles Basin, Eel River Basin, and Ventura Basin. The SAN Andreas fault became very active after the Miocene and had a profound effect on California's geology, possibly causing a crustal shift of up to 560 km. Together, these geological activities have shaped the topography of California, affected the distribution of its natural resources, and continue to have an impact on the geological stability and geomorphological evolution of California. [25]

landform

California is known for its extreme geographic diversity, with diverse landscapes ranging from vast coasts to mountains and deserts. Mt.Whitney and Death Valley are the highest and lowest points in the lower 48 states, respectively, highlighting the varied topography of the state. California has an average elevation of about 885 meters, and its major geographic areas include the Sierra Nevada Mountains to the east, the Coast Range to the west, the Central Valley, and the Mojave and Colorado Deserts to the southeast. The Central Valley is an agricultural powerhouse irrigated by the Sacramento and SAN Joaquin rivers, while the Coast Range is a mountain system that stretches for more than 1,900 kilometers and provides an important source of water for California. In addition, California has a number of peaks over 3,000 meters above sea level, such as Mount Williamson and Mount Shasta. The Yosemite Valley is a narrow canyon in the middle of the high mountains, while the Coast Range consists of forested ridges and ridges. As the earth's crust rose, forming the Sierra Nevada and the Coast Range, the earth's crust sank, forming the Central Valley and the Great Basin. [3] [26]

Hydrology and water conservancy

hydrology
California is home to numerous rivers and lakes, including the Sacramento River, Smith River, Klamath River, Lake Shasta, Lake New Melones and Lake Berissa. [27]
The Sacramento River
The Sacramento River [28]
The Sacramento River is the longest river in California, rising near Shasta Lake in the Cascade Mountains and flowing about 400 miles south through the Sacramento Valley before emptying into San Francisco Bay. The river is an important source of water for California, primarily used for agricultural irrigation, urban water supply, and hydroelectric power, as well as an important habitat for biodiversity, with wetlands and marsh areas along the river supporting rich wildlife. The Sacramento River Basin is one of California's major agricultural regions, producing a wide variety of crops and contributing significantly to the state economy. In addition, the Sacramento River is connected to the state's vast water infrastructure, including reservoirs, canals, and hydroelectric plants, and is a key component of California's water management. [28]
Water conservancy
The southern part of California is water-scarce, and an adequate water supply is essential for both agriculture and industry, so the state has built more than 1,000 DAMS and reservoirs. [26] its Among them are the Shasta Dam, Oroville Dam, Hoover Dam, Whiskeytown Dam and others. [28]
Shasta dam
Shasta dam [29]
The Shasta Dam is a concrete arch gravity dam across the Sacramento River in Mendocino County, northern California, United States. At about 183 meters high, the dam is the eighth tallest in the United States and supports Shasta Lake, one of the largest reservoirs in California, providing a variety of functions including flood control, irrigation, hydroelectric power and recreational activities. Shasta Dam is an important water facility in California, particularly critical to regional water management and agricultural irrigation. [29]

Natural disaster

Because of its special geographical location and changeable climate conditions, California often faces the threat of a variety of natural disasters, among which flood, fire and earthquake are the most important types of disasters in the state. Flooding caused by excessive rainfall and fires associated with strong winds and dry conditions are the most common disasters. For example, between 1950 and 2017, the Governor-General issued 309 emergency declarations, of which about 40 percent were flood-related and about 30 percent were fire-related. Although major earthquakes occur infrequently, accounting for only 7 percent of emergency declarations, they are potentially extremely destructive, having been responsible for two of the three deadliest disasters in history. [30]
flood
Certain areas of California are at higher risk of flooding due to geographic location and topographic features. Since 1992, every county in the state has been declared a federal disaster area at least once due to a flood event. Areas such as the Sacramento Valley, in particular, are more vulnerable to flooding due to their proximity to major rivers. Historically, California has experienced major flooding events, such as severe flooding in the central and northern regions in 1997, which affected 48 counties and caused $1.8 billion in economic damage. In recent years, unusually high rainfall in 2017 caused localized flooding, mudslides and road damage across much of the state, with the governor declaring a state of emergency in 52 counties. In particular, the erosion failure of the Oroville Dam spillway once threatened to cause catastrophic flooding, leading to the evacuation of nearly 200,000 residents, highlighting the severity of the flood disaster in the state and the urgency of disaster response. [30]
Fire hazard
Parts of California are at high to extreme risk of wildfires due to topography, climate and forest conditions, especially in most forested areas of the state. The frequency of severe fires has increased in recent years, with many of the largest and most destructive fires in history occurring in the last 20 years. Forest health problems, such as drought and bark beetle infestations, have killed large numbers of trees and increased fire risk. In addition, previous forest management practices, such as excessive suppression of naturally occurring moderate intensity fires, have resulted in increased vegetation density, providing more fuel for fires. The expansion of urbanization into high-risk areas has also contributed to the increase in fire losses. In 2018, California experienced some of the most destructive fires in its history, including the Mendocino Complex Fire, which burned more than 400,000 acres, and the Camp Fire, which destroyed more than 18,000 structures and caused insured losses estimated at $7 billion. [30]
earthquake
Parts of California, especially the San Francisco Bay Area and Los Angeles areas near important fault lines such as the SAN Andreas Fault, face a high risk of earthquake damage. The potential damage of an earthquake is not only determined by its magnitude, but is also affected by factors such as the depth of the earthquake, the distance from the epicenter, the intensity of the earthquake, the type of soil, and the density and type of local construction. California has experienced many devastating earthquakes in its history, such as the 1989 Loma Prieta earthquake, which killed 63 people and injured more than 3,700, and the 1994 Northridge earthquake, which killed 57 people and injured nearly 12,000, causing more than $15 billion in economic damage in then-dollar terms and $26 billion in 2018 dollars. [30]

Water resources

California's groundwater resources are extremely important, with total storage capacity estimated to be between 8.5 million and 13 million acre-feet, making available groundwater storage approximately eight to 12 times greater than the combined storage capacity of all major reservoirs in California. California has 515 defined groundwater basins, providing approximately 94 percent of the groundwater used statewide, with the remaining 6 percent coming from areas outside the basin. These groundwater basins provide critical water resources for agricultural, urban and environmental uses, especially during dry years when groundwater utilization increases significantly. However, groundwater levels have been declining in some areas due to over-pumping, particularly in the Central Valley, where aquifers have lost more than 100 million acre-feet of groundwater over the past 100 years. In addition, the depth of groundwater varies widely within the state, with a median depth of 57 feet underground in spring 2018, ranging from about 25 feet in the North Coast, San Francisco Bay, Sacramento River and North Lahontan Hydrology Area to 195 feet in the Tuleri Lake Hydrology Area. [31]
California manages its water resources by dividing them into ten major river basins, including the North Coast, Sacramento River, North Lahontan, San Francisco Bay, SAN Joaquin River, Central Coast, Tuleri Lake, South Lahontan, South Coast, and Colorado River areas. Each basin contains several river basins with similar climatic conditions, and the upper reaches of many basins have been used for hydroelectric power generation. California's surface water storage strategies are diverse, involving snow water, soil moisture, and surface reservoirs. As an important water source, snow water releases water during peak water use in spring and summer, while soil water supports plant growth and storm runoff regulation. There are approximately 1,500 reservoirs throughout the state with a total capacity of 43 million acre-feet, providing water necessary for agricultural, urban, and environmental needs. [32]

Land resources

California's land resources are extremely rich and diverse, including mountains, deserts, beaches, waters, and fertile valleys. The Central Valley, in particular, is a highly fertile agricultural region with the San Joaquin Series, California's official state soil, known for its characteristic duripan. The SAN Joaquin soil covers the ancient, vast, nearly flat surface of California's eastern Greater Central Valley, covering an area of approximately 438,000 acres. These soils are essential to California's agriculture, although they have certain limitations for irrigating crops and septic absorption fields. [33]

Forest and grass resources

As of 2016, California had approximately 33 million acres of forest, of which 57 percent (19 million acres) were controlled and managed by federal agencies, including the USDA Forest Service, USDA Land Management, and the National Park Service. State and local agencies, such as CAL Fire, local open space, parks, waters and land trusts, hold an additional 3 percent of the forest. The remaining 40 percent is owned by families, Native American tribes, or corporations. Industrial timber companies own 14 percent of the forest land, or 5 million acres. Another 9 million acres of forest are owned by individuals, with nearly 90 percent of individual woodland owners owning 50 acres or less. [34] There are about 52 conifer species in California, 14 of which are endemic and occur naturally only in the state. About 58% of the state's forests are dominated by conifers. [35] Mixed conifer types (primarily Douglas fir, ponderosa pine, sugar pine, Jeffrey pine, fragrant cedar, and white fir) cover approximately 7.8 million acres. Ponderosa pine type covers 2.2 million acres; Subalpine types (especially bristlecone pine and mountain hemlock) cover approximately 390,300 acres. Other western conifers cover about 1.5 million acres. Oak (hardwood) woodlands cover 13 million acres. [36]

Plant resources

California has six distinct life zones, including the Lower Sonoran (desert), the Upper Sonoran (foothills and parts of the coast), the Transition Zone (coastal and wet Northeast counties), and the Canada, Hudson, and Arctic Zones, the latter of which includes the highest elevations in California. These areas are rich in plant species, ranging from the native cacti and leguminous shrubs of the Sonoran Desert region to the Fremont poplar and Valley oak of the Central Valley to the endemic shrublands and herbs of the upper Sonoran region, as well as old-growth forests such as sequoias and giant sequoias of the transition region. The higher elevations of the Canadian region are dominated by Jeffery pine and red fir, while the Hudson Region is home to whitebark pine and bristlecone pine. The Arctic is a treeless region with a wide variety of wildflower species. In addition, California has introduced some exotic plants such as eucalyptus and acacia trees. The state is also home to many endangered species, including several federally protected plants, with 85 plants listed as threatened or endangered as of December 1997. [26]

Animal resources

California is extremely rich in biodiversity. In the deserts of the Lower Sonoran region, mammals such as jackrabbits, kangaroos, squirrels, and possums can be found, as well as birds such as Texas late sleepers, roadrunners, cactus wren, and many types of eagles, and reptile-representative animals in the region include rattlesnakes, desert turtles, and horned toads. The upper Sonoran region is home to mammals such as antelopes, brown-footed woodrats, and ring-tailed cats, and endemic bird species include the California Thrush, jungle tit, and California condors. The Transition Zone forests are rich in animal resources such as Columbia mule deer, black bears, gray foxes, cougars, bobcats, and Roosevelt elk, garter snakes and rattlesnakes are common reptiles, and amphibians such as polyps and redwood salamanders thrive here. California's aquatic ecosystem is equally rich, with a wide variety of trout from alpine lakes to the Pacific coastline, and deep-sea life including perch, yellowfin tuna, barracuda, and many species of whales. Seals, sea lions and many species of shorebirds along the Northern California coast, as well as migratory species, are also part of the state's natural landscape. However, California also faces conservation challenges, with 118 animal and 181 plant species on the federal endangered list as of April 2003, including multiple species of kangaroos, terns, bald eagles, salamanders, and killifish, as well as 11 species of butterflies. [26]

Mineral resources

California is known for its rich mineral resources and is one of the most mineral-rich states in the United States. Mineral resources in California include, but are not limited to, oil, natural gas, and metallic and nonmetallic minerals. Oil and natural gas are important energy minerals in California, which is the third largest oil producing state in the United States and has rich oil fields such as the Wilmington field near Los Angeles and the fields around Bakersfield. In the metal mining industry, California is particularly famous for gold mines, the historical gold rush occurred in the state, although gold production has declined, but California is still one of the main gold producing states in the United States. In addition, California also produces copper, tungsten, lead, zinc and other metal minerals. Non-metallic minerals such as sand, gravel and limestone are also abundant in building materials. [3] 37 - [38]

Nature reserve

California has a total of 290,821 acres (117,679 hectares) of land designated as a national wildlife refuge. [26] Including Antelope Valley California Poppy Reserve National Nature Reserve, Armstrong Redwood State Nature Reserve, Rhododendron National Nature Reserve and so on. [39]

summarize

The capital of California is Sacramento, and the state's political system is divided into three branches of government: the executive branch consists of the governor and other independently elected constitutional officers; The legislative branch consists of the Parliament and the Senate; The judicial branch consists of the California Supreme Court and its lower courts. In addition, California's electoral system allows voters to participate directly in the decision-making process through mechanisms such as initiatives, referendums, recall, and ratification. [52] Prior to the passage of Proposition 14 in 2010, parties were free to decide whether to adopt closed primaries or primaries that were limited to party members and independents. With the passage of the bill, all primary candidates, except for the office of President of the United States and the county Central Committee, would have their preferred party indicated next to their names, but the candidate was not the official party nominee. In the primary, the top two candidates with the most votes will advance to the general election regardless of party, and if a candidate receives more than 50% of the vote in the special primary, that candidate is directly elected without the need for a special election.

In the mid-twentieth century, Helen Evans Brown had a profound impact on modern California cuisine through her 1952 book, The Helen Brown West Coast Cookbook, in which she emphasized the use of the freshest local ingredients and produce, an idea that was adopted and developed by later chefs. [96]

Cioppino today preserves the tradition of using fresh seafood caught that day, which may include coarse crabs, clams, shrimp, scallops, squid, mussels, or a variety of fish. The seafood is mixed with fresh tomatoes and herbs and braised in a wine sauce to create a delicious dish.
