Northern California, often called NorCal, is the northern part of the U.S. state of California. It includes 48 of the state’s 58 counties and is home to many important places. Some of the biggest cities are in the San Francisco Bay Area, like San Jose, San Francisco, and Oakland. Other key areas include the Greater Sacramento region around the state capital, Sacramento, and places like Redding and Fresno.

Northern California has amazing natural beauty. It contains most of the Sierra Nevada mountains, including famous spots like Yosemite Valley and part of Lake Tahoe. The area also has the Cascade Range with Mount Shasta, one of the tallest peaks in the region. Many of the world’s largest companies, such as Alphabet Inc. (Google), Apple, Meta, and Nvidia, have their headquarters in Silicon Valley, which is located here.

People have lived in Northern California for thousands of years. Evidence shows that Native American groups were here at least 19,000 years ago. The first European settlement was a Spanish mission at Monterey in 1770, and more missions were built along the coast after that.

Description

North–south divisions of California

Map of northern California counties

During the gold rush in California from 1848 to 1855, many new people moved to the state, but most did not settle in the south. At that time, the northern two-thirds of California was considered the main part, simply called "California," while the southern part was known as "Southern California." A big mountain range called the Tehachapi Mountains made travel difficult before highways were built. These mountains stretch from the Pacific Ocean through several areas and separate the north from the south.

There have been ideas to split California into different parts. In 1859, a plan was made to create a new southern territory called the Territory of Colorado, but it was never approved. Some people still talk about dividing California in different ways. The exact middle of California is near the town of Morgan Hill, and some people in the far north have wanted to create a new state called Jefferson or split California into more states.

The Pico Act of 1859 proposed to divide California to create the Territory of Colorado in the south, with the northern area retaining the name of California.

Popular usage

The area along the coast north of the San Francisco Bay Area is called the North Coast, including places like Mendocino and Humboldt. The area north of Sacramento is sometimes called the Northstate and includes about 20 counties.

"Northern California" was once the name suggested for a new state if California were split into three parts, but this idea did not succeed.

Significance

Since the California Gold Rush, Northern California has been very important around the world in business, science, and culture. In the 1800s, people there developed new ways to mine gold and cut trees that others copied. Later, big companies like Apple, Hewlett-Packard, Google, Yahoo!, and eBay started there, changing how people do business.

Scientists in Northern California made big discoveries, like finding new elements and creating better computer chips. Famous artists and filmmakers such as Ansel Adams, George Lucas, and Clint Eastwood also came from this area. Northern California helped start movements like the beatniks, the Summer of Love, and winemaking. It was also where people first tried new, relaxed ways of working that are now used everywhere. Innovations include important medical advances and new fitness ideas. The area is also home to Travis Air Force Base, one of the largest Air Force bases on the West Coast.

Cities

Northern California’s largest area is the San Francisco Bay Area, which includes nine counties. Major cities in the Bay Area are San Jose, San Francisco, and Oakland, along with many smaller towns around them.

Other important cities in Northern California include Eureka, Redding, Chico, Yuba City, Fresno, and Visalia. San Jose is the biggest city in Northern California, while San Francisco is a key cultural and financial hub. Fresno is the largest city in the San Joaquin Valley, and Sacramento is the state’s capital. Oakland is an important port and home to many people.

History

Northern California has been home to many people for thousands of years. The area was first inhabited by Native American tribes, such as the Shasta, Miwoks, and Yokuts.

In the 1500s and 1600s, European explorers began to arrive. Spanish explorers sailed along the coast, and later, Spanish missionaries built settlements called missions along the coastline. In the early 1800s, Russia established a small trading post called Fort Ross.

After Mexico gained independence from Spain, it controlled the region. In the 1840s, American settlers began to move into the area. When the Mexican-American War began in 1846, some American settlers in northern California declared a small republic called the California Republic, which lasted only a short time before American forces took control.

The discovery of gold in 1848 brought a huge influx of people to the region, known as the Gold Rush. San Francisco grew quickly from a small village into a busy city. The Gold Rush also brought challenges, as new settlers often took land from the Native American tribes who had lived there for generations.

The years after the Gold Rush saw growth in population and farming. The building of railroads helped connect northern California to the rest of the country, bringing more people and goods. This time also brought new challenges, such as tensions over immigration and labor rights.

Prehistory to 1847

Inhabited for millennia by Native Americans, from the Shasta tribe in the north, to the Miwoks in the central coast and Sierra Nevada, to the Yokuts of the southern Central Valley, northern California was among the most densely populated areas of pre-Columbian North America.

European explorers

The first European to explore the coast was Juan Rodríguez Cabrillo, sailing for the Spanish Crown; in 1542, Cabrillo's expedition sailed perhaps as far north as the Rogue River in today's Oregon. Beginning in 1565, the Spanish Manila galleons crossed the Pacific Ocean from Mexico to the Spanish Philippines, with silver and gemstones from Mexico. The Manila galleons returned across the northern Pacific, and reached North America usually off the coast of northern California, and then continued south with their Asian trade goods to Mexico.

In 1579, northern California was visited by the English explorer Sir Francis Drake who landed north of today's San Francisco and claimed the area for England. In 1602, the Spaniard Sebastián Vizcaíno explored California's coast as far north as Monterey Bay, where he went ashore. Other Spanish explorers sailed along the coast of northern California for the next 150 years, but no settlements were established.

Spanish era

The first European inhabitants were Spanish missionaries, who built missions along the California coast. The mission at Monterey was first established in 1770, and at San Francisco in 1776. In all, ten missions stretched along the coast from Sonoma to Monterey (and still more missions to the southern tip of Baja California). In 1786, the French signaled their interest in the northern California area by sending a voyage of exploration to Monterey.

The first twenty years of the 19th century continued the colonization of the northern California coast by Spain. By 1820, Spanish influence extended inland approximately 25 to 50 miles (80 km) from the missions. Outside of this zone, perhaps 200,000 to 250,000 Native Americans continued to lead traditional lives. The Adams-Onís Treaty, signed in 1819 between Spain and the young United States, set the northern boundary of the Spanish claims at the 42nd parallel, effectively creating today's northern boundary of northern California.

Russian presence

In 1812, the Russian state-sponsored Russian-American Company established Fort Ross, a fur trading outpost on the coast of today's Sonoma County. Fort Ross was the southernmost Russian settlement, located some 60 miles (97 km) north of Spanish colonies in San Francisco. In 1839, the settlement was abandoned due to its inability to meet resource demands, and the increasing Mexican and American presence in the region.

Mexican era

After Mexico gained independence from Spain in 1821, Mexico continued Spain's missions and settlements in northern California as well as Spain's territorial claims. The Mexican Californios (Spanish-speaking Californians) in these settlements primarily traded cattle hides and tallow with American and European merchant vessels.

In 1825, the Hudson's Bay Company established a major trading post just north of today's Portland, Oregon. British fur trappers and hunters then used the Siskiyou Trail to travel throughout northern California. The leader of a further French scientific expedition to northern California, Eugene Duflot de Mofras, wrote in 1840 "...it is evident that California will belong to whatever nation chooses to send there a man-of-war and two hundred men.": 260   By the 1830s, a significant number of non-Californios had immigrated to northern California. Chief among these was John Sutter, a European immigrant from Switzerland, who was granted 48,827 acres (197.60 km2) centered on the area of today's Sacramento.

American interest

American trappers began entering northern California in the 1830s.: 263–4   In 1834, American visionary Ewing Young led a herd of horses and mules over the Siskiyou Trail from missions in northern California to British and American settlements in Oregon. Although a small number of American traders and trappers had lived in northern California since the early 1830s, the first organized overland party of American immigrants to arrive in northern California was the Bartleson-Bidwell Party of 1841 via the new California Trail.: 263–273   Also in 1841, an overland exploratory party of the United States Exploring Expedition came down the Siskiyou Trail from the Pacific Northwest. In 1846, the Donner Party earned notoriety as they struggled to enter northern California.

Californian independence and beginning of the United States era

When the Mexican–American War was declared on May 13, 1846, it took almost two months (mid-July 1846) for word to get to California. On June 14, 1846, some 30 non-Mexican settlers, mostly Americans, staged a revolt and seized the small Mexican garrison in Sonoma. They raised the "Bear Flag" of the California Republic over Sonoma. The "Bear Flag Republic" lasted only 26 days, until the U.S. Army, led by John Frémont, took over on July 9. The California state flag today is based on this original Bear Flag, and continues to contain the words "California Republic."

Commodore John Drake Sloat ordered his naval forces to occupy Yerba Buena (present San Francisco) on July 7 and within days American forces controlled San Francisco, Sonoma, and Sutter's Fort in Sacramento. The treaty ending the Mexican–American War was signed on February 2, 1848, and Mexico formally ceded Alta California (including all of present-day northern California) to the United States.

Gold Rush and California statehood

The California Gold Rush took place almost exclusively in northern California from 1848 to 1855. It began on January 24, 1848, when gold was discovered at Sutter's Mill in Coloma. News of the discovery soon spread, resulting in some 300,000 people coming to California from the rest of the United States and abroad. San Francisco grew from a tiny hamlet, home to about 1,000 Californios into a boomtown of over 50,000 people in the 12 years between 1848 and 1860. New roads, churches, and schools were built, and new towns sprung up, aided in part by the development of new methods of transportation such as steamships which came into regular service and railroads which now connected the coasts. The Gold Rush also had negative effects: American colonists chose to use genocide as a tool to remove the Indigenous people so that they could look for gold on their land.

The Gold Rush also increased pressure to make California a U.S. state. Pro-slavery politicians initially attempted to permanently divide northern and southern California at 36 degrees, 30 minutes, the line of the Missouri Compromise. But instead, the passing of the Compromise of 1850 enabled California to be admitted to the Union as a free state.

Population and agricultural expansion (1855–1899)

The decades following the Gold Rush brought dramatic expansion to northern California, both in population and economically – particularly in agriculture. The completion of the First transcontinental railroad in 1869, with its terminus in Sacramento (and then later, Oakland), meant that northern California's agricultural produce (and some manufactured goods) could now be shipped economically to the rest of the United States. In return, immigrants from the rest of the United States (and Europe) could comfortably come to northern California. A network of railroads spread throughout northern California, and in 1887, a rail link was completed to the Pacific Northwest. Almost all of these railways came under the control of the Southern Pacific Railroad, headquartered in San Francisco, and San Francisco continued as a financial and cultural center.

Substantial tensions during this era included nativist sentiments (primarily against Chinese immigrants), tensions between the increasing power of the Southern Pacific Railroad and small farmers, and the beginnings of the labor union movement.

Economy

Northern California is very important for many kinds of work, especially in making new technology like computer programs, tiny parts for electronics, medicines, and medical tools. The area is also good at making clean energy, and it has jobs in government, finance, travel, shipping, making things, and growing food. Many big companies and important offices, like the Federal Reserve and the 9th Circuit Court, have their places in San Francisco.

Climate

Northern California has a warm or mild to cool climate. The Sierra mountains get snow from late fall through winter and sometimes into spring. Summers are mild along the coast and usually warm and dry, while winters are cool and often wet.

High temperatures in winter range from the 50s °F (10–15 °C) to the 30s °F (−1 – +4 °C), and in summer from the 60s °F (15–20 °C) to the 90s °F (32–37 °C), with some areas, like the Sacramento region, reaching into the 100s °F (37–42 °C). Snow covers the mountains above 3,000 feet (910 m) from mid-January through February. Fog sometimes appears on the coast, especially in summer, making those areas some of the coolest places in North America. Since the early 2000s, droughts and wildfires have happened more often because of climate change.

Population

The population in the northern part of California has been growing steadily over the years.

The biggest growth happened in the 1940s when many veterans and their families moved there after World War II. They were drawn by new jobs in factories. The largest number of new people moved in during the 1980s, with over 2.1 million people coming because of job opportunities, especially in Silicon Valley and the defense industry during the Cold War. Since the year 2000, Northern California has grown faster than Southern California because of the strong economies in the Bay Area and Sacramento.
