History of San Francisco facts for kids
The history of the city of San Francisco, California, and its development as a center of maritime trade, were shaped by its location at the entrance to a large natural harbor. San Francisco is the name of both the city and the county, which share the same boundaries. Starting overnight as the base for the gold rush of 1849, the city quickly became the largest and most important population, commercial, naval, and financial center in the West. It was devastated by a great earthquake and fire in 1906 but was quickly rebuilt. The San Francisco Federal Reserve Branch opened in 1914, and San Francisco is ranked sixth on the Global Financial Centres Index (GFCI) and has grown wealthier by its proximity to Silicon Valley.

The earliest evidence of human habitation in what is now the city of San Francisco dates to 3000 BC. Native Americans who settled in this region found the bay to be a resource for hunting and gathering, leading to the establishment of many small villages. Collectively, these early Native Americans are now known as the Ohlone, and the language they spoke belonged to the Miwok family. Their trade patterns included places as far away as Baja California, the Mojave Desert and Yosemite.
The earliest Europeans to reach the site of San Francisco were a Spanish exploratory party in 1769, led overland from Mexico by Don Gaspar de Portolà and Fra. Juan Crespi. The Spanish recognized the location, with its large natural harbor, to be of great strategic significance. A subsequent expedition, led by Juan Bautista de Anza, selected sites for military and religious settlements in 1774. The Presidio of San Francisco was established for the military, while Mission San Francisco de Asís began the cultural and religious conversion of some 10,000 Ohlone who lived in the area. The mission became known as Mission Dolores, because of its nearness to a creek named after Our Lady of Sorrows.
The first anchorage was established at a small inlet on the north-east end of the peninsula (later filled: now lower Market Street), and the small settlement that grew up nearby was named Yerba Buena, after the herb of the same name that grew in abundance there. The original plaza of the Spanish settlement remains as Portsmouth Square. Today's city took its name from the mission, and Yerba Buena became the name of a San Francisco neighborhood now known as South of Market. The Moscone Center and Yerba Buena Gardens are in the Yerba Buena area. In addition, the name Yerba Buena was applied to the former Goat Island in the middle of San Francisco Bay, adjacent to Treasure Island.
European visitors to the San Francisco Bay Area were preceded at least 8,000 years earlier by Native Americans. According to one anthropologist, the indigenous name for San Francisco was "awaste", meaning, "place at the bay". Linguistic and paleontological evidence is unclear as to whether the earliest inhabitants of the area now known as San Francisco were the ancestors of the Ohlone population encountered by the Spanish in the late 18th century. The cultural unit, Ohlone, to which the San Francisco natives belonged did not recognize the city or county boundaries imposed later by Americans, and were part of a contiguous set of bands that lived from south of the Golden Gate to San José.
There is no mention of Native Americans in Sir Francis Drake's accounts of his trip to the San Francisco Bay in 1579, which is consistent with the seasonal use pattern of the area described in the archaeological record.
When the Spanish arrived, they found the area inhabited by the Yelamu tribe, which belongs to a linguistic grouping later called the Ohlone. The Ohlone speakers are distinct from Pomo speakers north of the San Francisco Bay, and are part of the Miwok group of languages. Their traditional territory stretched from Big Sur to the San Francisco Bay, although their trading area was much larger. Miwok-speaking Indians also lived in Yosemite, and Ohlone-speakers intermarried with Chumash and Pomo speakers as well.
The Spanish conquest of the San Francisco Bay area came later than to Southern California. San Francisco's characteristic foggy weather and geography led early European explorers such as Juan Rodríguez Cabrillo to bypass the Golden Gate and miss entering San Francisco Bay, although it seems clear from historical accounts of navigation that they passed close to the coastline north and south of the Golden Gate.
Arrival of Europeans and early settlement
A Spanish exploration party, led by Portolà and arriving on November 2, 1769, was the first documented European sighting of San Francisco Bay. Portolà claimed the area for Spain as part of the Viceroyalty of New Spain. Seven years later a Spanish mission, Mission San Francisco de Asís (Mission Dolores), was established by Fra. Junipero Serra, and a military fort was built, the Presidio of San Francisco.
In 1786 French explorer, the Comte de la Pérouse visited San Francisco and left a detailed account of it. Six years later, in 1792 British explorer George Vancouver also stopped in San Francisco, in part, according to his journal, to spy on the Spanish settlements in the area. In addition to Western Europeans, Russian fur-traders also visited the area. From 1770 until about 1841, Russian traders colonized an area that ranged from Alaska south to Fort Ross in Sonoma County, California. The naming of San Francisco's Russian Hill neighborhood is attributed to the remains of Russian fur-traders and sailors found there.
Upon independence from Spain in 1821, the area became part of Mexico. In 1835, Englishman William Richardson erected the first significant homestead outside the immediate vicinity of the Mission Dolores, near a boat anchorage around what is today Portsmouth Square. Together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena after the herb, which was named by the missionaries that found it abundant nearby, began to attract American settlers. In 1838, Richardson petitioned and received a large land grant in Marin County and, in 1841, he moved there to take up residence at Rancho Sauselito. Richardson Bay to the north bears his name.
The British Empire briefly entertained the idea of purchasing the bay from Mexico in 1841, claiming it would "Secure to Great Britain all the advantages of the finest port in the Pacific for her commercial speculations in time of peace, and in war for more easily securing her maritime ascendency". However little came of this, and San Francisco would become a prize of the United States rather than that of British naval power.
On July 31, 1846, Yerba Buena doubled in population when about 240 Mormon pioneers from the East coast arrived on the ship Brooklyn, led by Sam Brannan. Brannan, also a member of the Church of Jesus Christ of Latter Day Saints, would later become well known for being the first publicist of the California Gold Rush of 1849 and the first millionaire resulting from it.
US Navy Commodore John D. Sloat claimed California for the United States on July 7, 1846, during the Mexican–American War, and US Navy Captain John Berrien Montgomery and US Marine Second Lieutenant Henry Bulls Watson of the USS Portsmouth arrived to claim Yerba Buena two days later by raising the flag over the town plaza, which is now Portsmouth Square in honor of the ship. Henry Bulls Watson was placed in command of the garrison there. In August 1846, Lt. Washington A. Bartlett was named alcalde of Yerba Buena. On January 30, 1847, Lt. Bartlett's proclamation changing the name Yerba Buena to San Francisco took effect. The city and the rest of California officially became American in 1848 by the Treaty of Guadalupe Hidalgo, which ended the Mexican–American War. California was admitted to the U.S. as a state on September 9, 1850—the State of California soon chartered San Francisco and San Francisco County. At the time the county and city were not coterminous; the county contained modern-day northern San Mateo County.
Situated at the tip of a windswept peninsula without water or firewood, San Francisco lacked most of the basic facilities for a 19th-century settlement. These natural disadvantages forced the town's residents to bring water, fuel and food to the site. The first of many environmental transformations was the city's reliance on filled marshlands for real estate. Much of the present downtown is built over the former Yerba Buena Cove, granted to the city by military governor Stephen Watts Kearny in 1847.
1848 gold rush
The California gold rush starting in 1848 led to a large boom in population, including considerable immigration. Between January 1848 and December 1849, the population of San Francisco increased from 1,000 to 25,000. The rapid growth continued through the 1850s and under the influence of the 1859 Comstock Lode silver discovery. This rapid growth complicated city planning efforts, leaving a legacy of narrow streets that continues to characterize the city to this day. San Francisco became America's largest city west of the Mississippi River, until it lost that title to Los Angeles in 1920.
The population boom included many workers from China who came to work in the gold mines and later on the Transcontinental Railroad. The Chinatown district of the city became and is still one of the largest in the country; today as a result of that legacy, the city as a whole is roughly one-fifth Chinese, one of the largest concentrations outside of China. Many businesses founded to service the growing population exist today, notably Levi Strauss & Co. clothing, Ghirardelli chocolate, and Wells Fargo bank. Many famous railroad, banking, and mining tycoons or "robber barons" such as Charles Crocker, Mark Hopkins, Collis P. Huntington, and Leland Stanford settled in the city in its Nob Hill neighborhood. The sites of their mansions are now famous and expensive San Francisco hotels (Mark Hopkins Hotel and the Huntington Hotel).
As in many mining towns, the social climate in early San Francisco was chaotic. Committees of Vigilance were formed in 1851, and again in 1856, in response to crime and government corruption. This popular militia movement lynched 12 people, kidnapped hundreds of Irishmen and government militia members, and forced several elected officials to resign. The Committee of Vigilance relinquished power both times after it decided the city had been "cleaned up." This mob activity later focused on Chinese immigrants, creating many race riots. These riots culminated in the creation of the Chinese Exclusion Act in 1882 that aimed to reduce Chinese immigration to the United States by limiting immigration to males and reducing numbers of immigrants allowed in the city. The law was not repealed until 1943 with the Magnuson Act.
San Francisco was the county seat of San Francisco County, one of state's 18 original counties since California's statehood in 1850. Until 1856, the city limits extended west to Divisadero Street and Castro Street, and south to 20th Street. In response to the lawlessness and vigilantism that escalated rapidly between 1855 and 1856, the California government decided to divide the county. A straight line was then drawn across the tip of the San Francisco Peninsula just north of San Bruno Mountain. Everything south of the line became San Mateo County while everything north of the line became the new consolidated City and County of San Francisco, to date the only consolidated city-county in California.
In autumn of 1855, a ship bearing refugees from an ongoing cholera epidemic in the Far East (authorities disagree as to whether this was the S.S. Sam or the S.S. Carolina but primary documents indicate that the Caroline was involved in the epidemic of 1850 and the SS Uncle Sam in the epidemic of 1855) docked in San Francisco. As the city's rapid Gold Rush area population growth had significantly outstripped the development of infrastructure, including sanitation, a serious cholera epidemic quickly broke out. The responsibility for caring for the indigent sick had previously rested on the state, but faced with the San Francisco cholera epidemic, the state legislature devolved this responsibility to the counties, setting the precedent for California's system of county hospitals for the poor still in effect today. The Sisters of Mercy were contracted to run San Francisco's first county hospital, the State Marine and County Hospital, due to their efficiency in handling the cholera epidemic of 1855. By 1857, the order opened St. Mary's Hospital on Stockton Street, the first Catholic hospital west of the Rocky Mountains. In 1905, The Sisters of Mercy purchased a lot at Fulton and Stanyan Streets, the current location of St. Mary's Medical Center, the oldest continually operating hospital in San Francisco.
Paris of the West
It was during the 1860s to the 1880s when San Francisco began to transform into a major city, starting with massive expansion in all directions, creating new neighborhoods such as the Western Addition, the Haight-Ashbury, Eureka Valley, the Mission District, culminating in the construction of Golden Gate Park in 1887. The City's famous Cable Cars were built around this time, a unique invention devised by Andrew Smith Hallidie in order to traverse the City's steep hills while connecting the new residential developments. San Francisco grew in cultural prominence at this time as famous writers Mark Twain, Bret Harte, Ambrose Bierce, Rudyard Kipling, Robert Louis Stevenson, and Oscar Wilde spent time in the city, while local characters developed such as Emperor Norton.
By the 1890s, much like across the United States, San Francisco was suffering from machine politics and corruption, and was ripe for political reform. Adolph Sutro ran for mayor in 1894 under the auspices of the Populist Party and won handily without campaigning. Unfortunately, except for the Sutro Baths, Mayor Sutro substantially failed in his efforts to improve the city.
The next mayor, James D. Phelan elected in 1896, was more successful, pushing through a new city charter that allowed for the ability to raise funds through bond issues. He was able to get bonds passed to construct a new sewer system, seventeen new schools, two parks, a hospital, and a main library. After leaving office in 1901, Phelan became interested in remaking San Francisco into a grand and modern Paris of the West.
In 1900, a ship brought with it rats infected with bubonic plague to initiate the San Francisco plague of 1900–1904; the first plague epidemic in the continental US. Mistakenly believing that interred corpses contributed to the transmission of plague, and possibly also motivated by the opportunity for profitable land speculation, city leaders banned all burials within the city. Cemeteries moved to the undeveloped area just south of the city limit, now the town of Colma, California. A fifteen-block section of Chinatown was quarantined while city leaders squabbled over the proper course to take, but the outbreak was finally eradicated by 1905. However, the problem of existing cemeteries and the shortage of land in the city remained. In 1912 (with fights extending until 1942), all remaining cemeteries in the city were evicted to Colma, where the dead now outnumber the living by more than a thousand to one. The above-ground Columbarium of San Francisco was allowed to remain, as well as the historic cemetery at Mission Dolores, the grave of Thomas Starr King at the Unitarian Church, and the San Francisco National Cemetery at the Presidio of San Francisco.
1906 earthquake and fire
On April 18, 1906, a devastating earthquake resulted from the rupture of over 270 miles of the San Andreas Fault, from San Juan Bautista to Eureka, centered immediately offshore of San Francisco. The quake is estimated by the USGS to have had a magnitude of 7.8 on the Richter scale. Water mains ruptured throughout San Francisco, and the fires that followed burned out of control for days, destroying approximately 80% of the city, including almost all of the downtown core. Many residents were trapped between the water on three sides and the approaching fire, and a mass evacuation across the Bay saved thousands. Refugee camps were also set up in Golden Gate Park, Ocean Beach, and other undeveloped sections of the city. The official death toll at the time was 478, although it was officially revised in 2005 to 3,000+. The initial low death toll was concocted by civic, state, and federal officials who felt that reporting the actual numbers would hurt rebuilding and redevelopment efforts, as well as city and national morale. The death toll from this event had the highest number of deaths from a natural disaster in California history.
Almost immediately after the quake re-planning and reconstruction plans were hatched to quickly rebuild the city. One of the more famous and ambitious plans, proposed before the fire, came from famed urban planner, Daniel Burnham. His bold plan called for Haussmann style avenues, boulevards, and arterial thoroughfares that radiated across the city, a massive civic center complex with classical structures, what would have been the largest urban park in the world, stretching from Twin Peaks to Lake Merced with a large athenaeum at its peak, and various other proposals. This plan was dismissed at the time and by critics now, as impractical and unrealistic to municipal supply and demand. Property owners and the Real Estate industry were against the idea as well due to the amounts of their land the city would have to purchase to realize such proposals. While the original street grid was restored, many of Burnham's proposals eventually saw the light of day such as a neo-classical civic center complex, wider streets, a preference of arterial thoroughfares, a subway under Market Street, a more people friendly Fisherman's Wharf, and a monument to the city on Telegraph Hill, Coit Tower.
"Greater San Francisco" movement of 1912
In 1912, there was a movement to create a Greater San Francisco in which southern Marin County, the part of Alameda County which includes Oakland, Piedmont and Berkeley, and northern San Mateo County from San Bruno northwards would have become outer Boroughs of San Francisco, with the City and County of San Francisco functioning as Manhattan, based on the New York City model. East Bay opposition defeated the San Francisco expansion plan in the California legislature, and later attempts at San Francisco Bay Area metropolitan area consolidation in 1917, 1923, and 1928 also failed to be implemented.
Panama–Pacific Exposition of 1915
In 1915, the city hosted the Panama–Pacific International Exposition, officially to celebrate the opening of the Panama Canal, but also as a showcase of the vibrant completely rebuilt city less than a decade after the Earthquake. After the exposition ended, all of its grand buildings were demolished except for the rebuilt Palace of Fine Arts which survives today in an abbreviated form, while the remainder of the fairgrounds were re-developed into the Marina District.
1930s – World War II
1934 saw San Francisco become the center of the West Coast waterfront strike. The strike lasted eighty-three days and saw the deaths of two workers, but the result led to the unionization of all of the West Coast ports of the United States.
The San Francisco–Oakland Bay Bridge was opened in 1936 and the Golden Gate Bridge in 1937. The 1939 Golden Gate International Exposition was held on Treasure Island. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, The Birdman of Alcatraz.
During World War II, San Francisco was the major mainland supply point and port of embarkation for the war in the Pacific. It also saw the largest and oldest enclave of Japanese outside of Japan, Japantown, completely empty out many of its residents as a result of Executive Order 9066 that forced all Japanese of birth or descent in the United States to be interned. By 1943 many large sections of the neighborhood remained vacant due to the forced internment. The void was quickly filled by thousands of African Americans who had left the South to find wartime industrial jobs in California as part of the Great Migration. Many African Americans also settled in the Fillmore District and most notably near the Bayview-Hunters Point shipyards, working in the dry-docks there. The same docks at Hunters Point would be used for loading the key fissile components of the first atomic bomb onto the USS Indianapolis in July 1945 for transfer to Tinian.
The War Memorial Opera House which opened in 1932, was the site of some significant post World War II history. In 1945, the conference that formed the United Nations was held there, with the UN Charter being signed nearby in the Herbst Theatre on June 26. Additionally the Treaty of San Francisco which formally ended war with Japan and established peaceful relations, was drafted and signed here six years later in 1951.
Post-World War II
After World War II, many American military personnel, who fell in love with the city while leaving for or returning from the Pacific, settled in the city, prompting the creation of the Sunset District, Visitacion Valley, and the total build out of San Francisco. During this period, Caltrans commenced an aggressive freeway construction program in the Bay Area. However, Caltrans soon encountered strong resistance in San Francisco, for the city's high population density meant that virtually any right-of-way would displace a large number of people. Caltrans tried to minimize displacement (and its land acquisition costs) by building double-decker freeways, but the crude state of civil engineering at that time resulted in construction of some embarrassingly ugly freeways which ultimately turned out to be seismically unsafe. In 1959, the Board of Supervisors voted to halt construction of any more freeways in the city, an event known as the Freeway Revolt. Although some minor modifications have been allowed to the ends of existing freeways, the city's anti-freeway policy has remained in place ever since.
The San Francisco Mental Hygiene Society was formed in 1947. In 1958 the New York Giants moved to San Francisco and became the San Francisco Giants. Their first stadium, Candlestick Park, was constructed in 1959.
In the 1950s San Francisco mayor George Christopher hired M. Justin Herman to head the redevelopment agency for the city and county. Justin Herman began an aggressive campaign to tear down blighted areas of the city that were really working class, non-white neighborhoods. Enacting eminent domain whenever necessary, he set upon a plan to tear down huge areas of the city and replace them with modern construction. Critics accused Herman of racism for what was perceived as attempts to create segregation and displacement of blacks. Many black residents were forced to move from their homes near the Fillmore jazz district to newly constructed projects such as near the naval base at Hunter's Point or even to other cities such as Oakland. He began leveling entire areas in San Francisco's Western Addition and Japantown neighborhoods. Herman also completed the final removal of the produce district below Telegraph Hill, moving the produce merchants to the Alemany Boulevard site. His planning led to the creation of Embarcadero Center, the Embarcadero Freeway, Japantown, the Geary Street superblocks, and eventually Yerba Buena Gardens.
1960 – 1970s
"Summer of Love" and counterculture movement
- See also: History of the hippie movement
Following World War II, San Francisco became a magnet for America's counterculture. During the 1950s, City Lights Bookstore in the North Beach neighborhood was an important publisher of Beat Generation literature. Some of the story of the evolving arts scene of the 1950s is told in the article San Francisco Renaissance. During the latter half of the following decade, the 1960s, San Francisco was the center of hippie and other alternative culture.
In 1967, thousands of young people entered the Haight-Ashbury district during what became known as the Summer of Love. The San Francisco Sound emerged as an influential force in rock music, with such acts as Jefferson Airplane and the Grateful Dead achieving international prominence. These groups blurred the boundaries between folk, rock and jazz traditions and further developed rock's lyrical content.
During the administration of Mayor Dianne Feinstein (1978 – 1988), San Francisco saw a development boom referred to as "Manhattanization." Many large skyscrapers were built—primarily in the Financial District—but the boom also included high-rise condominiums in some residential neighborhoods. An opposition movement gained traction among those who felt the skyscrapers ruined views and destroyed San Francisco's unique character. Similar to the freeway revolt in the city decades earlier, a "skyscraper revolt" forced the city to embed height restrictions in the planning code. For many years, the limits slowed construction of new skyscrapers. She had also spearheaded the development and construction of the city's convention center, the Moscone Center, preserved and renovated the city's Cable Cars, and attracted the 1984 Democratic National Convention.
During the early 1980s, homeless people began appearing in large numbers in the city, the result of multiple factors including the closing of state institutions for the mentally ill, the Reagan administration drastically cutting Section 8 housing benefits, and social changes which increased the availability of addictive drugs. Combined with San Francisco's attractive environment and generous welfare policies the problem soon became endemic. Mayor Art Agnos (1988 – 92) was the first to attack the problem, and not the last; it is a top issue for San Franciscans even today. His program, Beyond Shelter, became the basis for federal programs and was recognized by Harvard for Innovations in Local Government.
In August 1989, San Francisco was surpassed for the first time in population by San Jose (located in Silicon Valley), the world center of the computer industry. San Jose has continued since then to grow in population since it is surrounded by large tracts of developable land. Thus, San Francisco is now the second largest city in population in the San Francisco Bay Area after San Jose.
1989 Loma Prieta earthquake
On October 17, 1989, an earthquake measuring 6.9 on the moment magnitude scale struck on the San Andreas Fault near Loma Prieta Peak in the Santa Cruz mountains, approximately 70 miles (113 km) south of San Francisco, a few minutes before Game 3 of the 1989 World Series was scheduled to begin at Candlestick Park. The quake severely damaged many of the city's freeways including the Embarcadero Freeway and the Central Freeway. Mayor Agnos made the controversial decision to tear down the Embarcadero Freeway, opening the waterfront but eventually shifting Chinatown voters away from him and costing him re-election in 1991. The quake also caused extensive damage in the Marina District and the South of Market neighborhoods.
The 1990s saw the demolition of the quake damaged Embarcadero and Central Freeway, restoring the once blighted Hayes Valley as well as the city's waterfront promenade, The Embarcadero. In 1994 as part of the Base Realignment and Closure plan, the former military base of San Francisco Naval Shipyard in Bayview-Hunters Point was closed and returned to the city while the Presidio was turned over to the National Park Service and since converted into a national park.
In 1996, the city elected its first and to date only African American mayor, former Speaker of the California State Assembly, Willie Brown. Brown called for expansions to the San Francisco budget to provide for new employees and programs. During Brown's tenure, San Francisco's budget increased to US$5.2 billion and the city added 4,000 new employees. His tenure saw the development and construction of the new Mission Bay neighborhood, and a baseball stadium for the Giants, AT&T Park which was 100% privately financed.
During the dot-com boom of the late 1990s, large numbers of entrepreneurs and computer software professionals moved into the city, followed by marketing and sales professionals, and changed the social landscape as once poorer neighborhoods became gentrified. The rising rents forced many people, families, and businesses to leave. San Francisco has the smallest share of children of any major U.S. city, with the city's 18 and under population at just 13.4 percent.
In 2001, the markets crashed, the boom ended, and many left San Francisco. South of Market, where many dot-com companies were located, had been bustling of empty offices and for-rent signs. Much of the boom was blamed for the city's "fastest shrinking population", reducing the city's population by 30,000 in just a few years. While the bust has helped put an ease on the city's apartment rents, the city remains expensive. By 2003, the city's economy had recovered from the dot-com crash thanks to a resurgent international tourist industry and the Web 2.0 boom that saw the creation of many new internet and software start-up companies in the city, attracting white-collar workers, recent University graduates, and young adults from all over the world. Residential demand as well as rents rose again, and as a result city officials relaxed building height restrictions and zoning codes to construct residential condominiums in SOMA such as One Rincon Hill, 300 Spear Street, and Millennium Tower, although the late 2000s recession has indefinitely halted many construction projects such as Rincon Hill. Part of this development is the reconstruction of the Transbay Terminal Replacement Project.
2010 saw the San Francisco Giants win their first World Series title since moving from New York City. The estimated 1 million people who attended their victory parade is considered one of the largest in city history. 2012 saw the Giants win their second title in San Francisco. Celebrations citywide were marred by rioting which caused millions of dollars in property damage.
In 2011, city manager Edwin Lee was elected the first Chinese American mayor in any American major city. Mayor Lee has been a strong proponent of tenant's rights, but also a business-friendly mayor to the city's burgeoning tech community.
By 2013, San Francisco, with thanks from the Web 2.0 boom, had fully recovered from the late 2000s recession and is experiencing a real estate and population boom. The computer industry is moving north from Silicon Valley. Availability of vacant rental units is scarce and the prices for vacant units has increased dramatically, and as of 2015 is reported to be the highest in the nation.
In April 2016, the city passed a law requiring all new buildings below 10 stories to have rooftop solar panels, making it the first major US city to do so.
