History

The original inhabitants of the area now known as Humboldt County include the Algic Wiyot, Yurok; the Hokan Karuk; and the Athapaskan Hupa, Chilula, Whilkut, Tsnungwe as well as the Eel River Athapaskan peoples, including the Wailaki, Mattole and Nongatl.
Spanish traders made unintended visits to California with the Manila Galleons on their return trips from the Philippines beginning in 1565. The first recorded entry by people of European origin was a landing by the Spanish in 1775 in Trinidad.
The first recorded entry of Humboldt Bay by non-natives was an 1806 visit from a sea otter hunting party from Sitka employed by the Russian-American Company. The party included New England captain Jonathan Winship, Russian supervisors, and Aleut hunters. The bay was not visited again by people of European origin until 1849 when Josiah Gregg's party arrived. The following year Douglas Ottinger and Hans Buhne sailed the schooner Laura Virginia into the bay. One of the pioneering passengers, Steven W. Shaw, proposed that the Laura Virginia Association name the bay Humboldt in honor of the naturalist and explorer Alexander von Humboldt. The name was later applied to the county as a whole.
The area around Humboldt Bay was once solely inhabited by the Wiyot Indian tribe. One of the largest Wiyot villages, Tolowot, was located on Indian Island in Humboldt Bay. Founded around 900 BC, it contains a shell midden in size and deep. It was the site of the February 26, 1860, massacre of the Wiyot people that was recorded by Bret Harte, then living in Union, now called Arcata. Between 60 and 200 Wiyot men, women, and children were murdered that night in the midst of a religious ceremony. Tolowot is now a restricted site and a National Historic Landmark. In 2019, the island was restored to the Wiyot tribe, and is now known as Tuluwat or Duluwat island.
Humboldt County was formed in 1853 from parts of Trinity County.
State historic landmarks in Humboldt County include Mad River Railroad, California's First Drilled Oil Wells in Petrolia, Camp Curtis, Centerville Beach Cross, the city of Eureka, the Victorian town of Ferndale, Fort Humboldt, Humboldt Harbor Historical District, the Jacoby Building, The Old Arrow Tree, [Tsurau, California|Old Native Americans in the United States|Indian Village of Tsurai], the Town of Trinidad, and Trinidad Head.
On February 5 and 6, 1885, Eureka's entire Chinese population of 300 men and 20 women were expelled after a gunfight between rival Chinese gangs resulted in the wounding of a 12-year-old boy and the death of 56-year-old David Kendall, a Eureka City Councilman. After the shooting, an angry mob of 600 Eureka residents met and informed the Chinese that they were no longer wanted in Eureka and would be hanged if they were to stay in town past 3 p.m. the next day. They were put on two steamships and shipped to San Francisco. No one was killed in the expulsion. Another Chinese expulsion occurred during 1906 in a cannery on the Eel River, in which 23 Chinese cannery workers were expelled after objections to their presence. However, some Chinese remained in the Orleans area, where some white landowners sheltered and purchased food for the Chinese mineworkers until after racial tension passed. Chinese did not return to the coastal cities until the 1950s.

Economy

The lush river bottoms adjacent to the ocean produce rich, high-quality dairy products. Somewhat further inland, the warmer valleys have historically produced abundant apples and other fruit. More recently vineyards have been planted in the Trinity, Klamath, Mattole and upper Eel river areas.
Notable local companies include:

Dairy

Humboldt County is known for its family-operated dairy farms. The Humboldt Creamery, a significant producer of high-grade ice cream and other dairy products, operates from the original headquarters located at Fernbridge adjacent to the Eel River.

Cannabis

As part of the Emerald Triangle, Humboldt County is known for its cultivation of cannabis, estimated to be worth billions of dollars. Proposition 215 allows patients and caregivers who are given a doctor's recommendation to legally grow up to 99 plants in Humboldt County. However, in the years before Prop 215, Humboldt County saw a large migration of the Bay Area counter-culture to the region. Many came looking to purchase cheap land, and ended up growing marijuana to pay for their land. Especially around Garberville and Redway, the rural culture and hippie scene eventually collaborated to create a rural hippie community in which marijuana became the center of the economy and the culture. Many people prospered by producing marijuana for California and other states because of its reputation for quality. A Redway radio station, KMUD, in the past has issued warnings and alerts to the region with information on whereabouts of law enforcement on their way to raid marijuana gardens.
The Campaign Against Marijuana Planting is the multi-agency law enforcement task force managed by the California Department of Justice, formed with the prime purpose of eradicating illegal cannabis production in California. The operations began in the late 1970s, named the Northern California Sinsemilla Strike Force in 1979, but the name CAMP became used after its official establishment in 1983. While the influence of CAMP in Humboldt County has waned with decriminalization of marijuana, there is a renewed interest at the state level regarding valid growing permits and environmental concerns. As a result, CAMP is today still used as a policing body, in accordance with the DEA. Yearly CAMP reports, published by the California Department of Justice, Bureau of Narcotic Enforcement are available online through Cal Poly Humboldt's Special Collections. Starting in 1983, the annual reports detail the organizational structure and names of individual participants, a summary of the season's activities, tactics, and mention of special successes, trends and hazards.
County officials and the industry have encountered challenges in the transition from an illegal, underground economy to legal recreational cannabis sales that began in California in 2018.
As of 2023, the county has the largest cannabis farming industry in the Emerald Triangle. While the largest legal pot farm in the county was, a 2021 survey found the median pot farm sito be as.

Lead poisoning (2017–2018)

Humboldt County children are at greater risk of dangerously elevated blood lead levels than Flint, Michigan's – and almost double that of any other California county measured. The cases are concentrated in Eureka's Old Town and downtown areas.

Books

In the book Lolita by Vladimir Nabokov there is a possible pun using the county's name in connection to the main character's name. This appears on page 108: "With the help of a guidebook I located in the secluded town of Briceland." This 'secluded town' could very well be a reference to the unincorporated Briceland of Humboldt County, making The Enchanted Hunters in 'Humboldt Land', continuing the novel's grotesque fairy-tale veneer.

Indian reservations

Humboldt County has eight Indian reservations lying within its borders. Only four other counties in the United States have more: San Diego County, California; Sandoval County, New Mexico; Riverside County, California; and Mendocino County, California. The Hoopa Valley Indian Reservation is the largest in the state of California, a state that generally has small reservations relative to those in other states.
