Fort Ross is a former Russian establishment on the west coast of North America in what is now Sonoma County, California, United States. It was the first multi-ethnic community north of the Spanish missions in what is now the U.S. state of California. Owned and operated by the Russian-American Company, it was the hub of the southernmost Russian settlements in North America from 1812 to 1841. Notably cosmopolitan, different ethnic groups settled in and around the fort: Native Californians, Native Alaskans, Russians, Finns, Swedes. It has been the subject of archaeological investigation and is a California Historical Landmark, a National Historic Landmark, and on the National Register of Historic Places. It is part of California's Fort Ross State Historic Park.

Etymology The present name, Fort Ross, appears first on a French chart published in 1842 by Eugène Duflot de Mofras, who visited California in 1840. The name of the fort is said to derive from the Russian word rus or ros, the same root as the word "Russia" (, Rossiya) (Fort Ross (Russian: Форт-Росс, Kashaya mé·ṭiʔni), originally Fortress Ross (pre-reformed Russian: Крѣпость Россъ, tr. Kriepostʹ Ross). According to William Bright, "Ross" is a poetic name for a Russian in the Russian language. The Spanish sometimes called it Presidio Ruso or Presidio de Bodega.

History Beginning with Columbus in 1492, the Spanish presence in the Western Hemisphere traveled west across the Atlantic Ocean, then around or across the Americas to reach the Pacific Ocean; Misión San Diego was settled in 1769 and in 1777 the Presidio de Monterey was made the capital of Provincía de Las Californias. The Russian expansion moved east across Siberia and the northern Pacific. In 1799 the Russians established a colony in Alaska. In the early nineteenth century, Spanish and Russian expansion met along the coast of Spanish Alta California, with Russia pushing south and Spain pushing north. By that time, British and American fur trade companies had also established a coastal presence, in the Pacific Northwest, and Mexico was soon to gain independence. Mexico ceded Alta California to the United States following the Mexican–American War (1848). The history of the Russian Fort Ross settlement began during Spanish rule and ended under Mexican rule.

Earliest people The earliest people known to have lived at the site were there during the Upper Archaic period (1000 B.C. – A.D. 500) and the Lower Emergent period (A.D. 1000–1500), but the main occupation began at A.D. 1500 and continued through 1812. Archaeological and ethnographic evidence suggest that the Native Californians lived in large and mostly permanent villages. In summer months, they had "special purpose camps" they would go to in order to get certain resources. This area was one of such camps, used for its access to tidal and marine resources.

Ethnographic evidence suggests that the area where Fort Ross would be located was a large part of Kashaya Pomo territory. Their name for the site was "Metini". Their exact arrival date is unknown, but according to linguistic and archaeological data, they moved to Metini sometime between 1,000 and 500 B.C. Archaeological data shows that the Kashaya Pomo increased their subsistence activities upon arrival at this site and gained greater diversity in their tool kits.

Russian-American Company Russian personnel from the Alaskan colonies initially arrived in California aboard American ships. In 1803, American ship captains already involved in the sea otter maritime fur trade in California proposed several joint venture hunting expeditions to Alexander Andreyevich Baranov, on half shares using Russian supervisors and native Alaskan hunters to hunt fur seals and otters along the Alta and Baja Californian coast. Subsequent reports by the Russian hunting parties of uncolonized stretches of coast encouraged Baranov, the Chief Administrator of the Russian-American Company (RAC), to consider a settlement in California north of the limit of Spanish occupation in San Francisco. In 1806 the Russian Ambassador to Japan, and RAC director Nikolay Rezanov, undertook an exploratory trade mission to California to establish a formal means of procuring food supplies for his Alaskan colony in exchange for Russian goods in San Francisco. While guests of the Spanish, Rezanov's captain, Lt. Khvostov, explored and charted the coast north of San Francisco Bay and found it completely unoccupied by other European powers. Upon his return to Novoarkhangelsk (New Archangel), Rezanov recommended to Baranov, and the Emperor Alexander, that a settlement be established in California.

Fort Ross was established by Commerce Counselor Ivan Kuskov of the Russian-American Company.The Destiny of Russian AmericaKhlebnikov, K. T., 1973, Baranov, Chief Manager of the Russian Colonies in America, Kingston: The Limestone Press, . In 1808 Baranov sent two ships, the Kad'yak and the Sv. Nikolai, on an expedition south to establish settlements for the RAC with instructions to bury "secret signs" (possession plaques). Kuskov, on the Kad'yak, was instructed to bury the plaques, with an appropriate possession ceremony, at Trinidad, Bodega Bay, and on the shore north of San Francisco, indicating Russian claims to the land. After sailing into Bodega Bay in 1809 on the Kad'yak and returning to Novoarkhangelsk with beaver skins and 1,160 otter pelts, Baranov ordered Kuskov to return and establish an agricultural settlement in the area. After a failed attempt in 1811, Kuskov sailed the brig Chirikov back to Bodega Bay in March 1812, naming it the Gulf of Rumyantsev or Rumyantsev Bay (, Zaliv Rumyantseva) in honor of the Russian Minister of Commerce Count Nikolai Petrovich Rumyantzev. He also named the Russian River the Slavic River (, Slavyanka). On his return, Kuskov found American otter hunting ships and otter now scarce in Bodega Bay. After exploring the area they ended up selecting a place north that the native Kashaya Pomo people called Mad shui nui or Metini. Metini, the seasonal home of the Kashaya Pomo, had a modest anchorage and abundant natural resources and would become the Russian settlement of Fortress Ross.

Fort Ross was established as an agricultural base from which the northern settlements could be supplied with food, while also continuing trade with Alta California. Yet during its initial ten years of operations the post "provided the company with nothing but heavy expenses for its maintenance."Tikhmenev, P. A. A History of the Russia-American Company. ed. Richard A. Pierce and Alton S. Donnelly. Seattle: University of Washington Press. 1978, p. 141. Fort Ross itself was the hub of a number of smaller Russian settlements comprising what was called "Fortress Ross" on official documents and charts produced by the Company itself.Fort Ross and the Sonoma Coast Colony Ross referred to the entire area where Russians had settled. These settlements constituted the southernmost Russian colony in North America and were spread over an area stretching from Point Arena to Tomales Bay.Historical Atlas of California The colony included a port at Bodega Bay called Port Rumyantsev (), a sealing station on the Farallon Islands out to sea from San Francisco, and by 1830 three small farming communities called "ranchos" (): Chernykh (, Rancho Egora Chernykh) near present-day Graton, Khlebnikov (, Rancho Vasiliya Khlebnikova) a mile north of the present day town of Bodega in the Salmon Creek valley, and Kostromitinov (, Rancho Petra Kostromitinova) on the Russian River.

Local enterprise In addition to farming and manufacturing, the Company carried on its fur-trading business at Fort Ross, but by 1817, after 20 years of intense hunting by Spanish, American and British ships—followed by Russian efforts—sea otters had been practically eliminated from the area.

Fort Ross was the site of California's first windmills and shipbuilding. Russian scientists associated with the colony were among the first to record California's cultural and natural history.Fort Ross Interpretive Association The Russian managers introduced many European innovations such as glass windows, stoves, and all-wood housing into Alta California. Together with the surrounding settlement, Fort Ross was home to Russian subjects, who included various ethnicities native to Eastern Europe and Asia,Pierce as well as North Pacific Natives, Aleuts, Kashaya (Pomo), and Alaskan Creoles. The native populations of the Sonoma and Napa County regions were affected by smallpox, measles and other infectious diseases that were common across Asia, Europe, and Africa. One instance can be traced to the settlement of Fort Ross.Silliman 2004. The first vaccination in California history was carried out by the crew of the Kutuzov, a Russian-American Company vessel arriving from Callao, Peru which brought vaccine to Monterey in August 1821. The Kutuzov's surgeon vaccinated 54 people. Another instance of disease prevention was when a visiting Hudson's Bay Company hunting party was refused entry to the Colony in 1833, when it was feared that a malaria epidemic which had devastated the Central Valley was carried by its members. In 1837 a very deadly epidemic of smallpox that came from this settlement via New Archangel wiped out most native people in the Sonoma and Napa County regions.

Mexican response Between 1824 and 1836 the Mexicans found during every exploratory effort north of present-day San Rafael and west of Sonoma increasing evidence of Russian presence. They discovered at least three Russian farms that had been established inland from Fort Ross. Governor José Figueroa wanted to counter the Russians' gradual encroachment in Northern California. In 1834, he granted Rancho Petaluma to Mariano Guadalupe Vallejo. In 1835 he appointed Vallejo as Comandante of the Fourth Military District and Director of Colonization of the Northern Frontier, the highest military command in Northern California, and encouraged him to build the Presidio of Sonoma. To extend the settlements in the direction of Fort Ross, Vallejo granted his brother-in-law, Captain John B. R. Cooper, who had married his sister Encarnacion, Rancho El Molino (about ). The grant was confirmed by Governor Nicolás Gutiérrez in 1836.Ogden Hoffman, 1862, Reports of Land Cases Determined in the United States District Court for the Northern District of California, Numa Hubert, San Francisco.

Upon his arrival in Alta California in 1839, John Sutter was attracted to the land near the Sacramento River. To obtain the land and permission to settle in the territory, he went to the capital at Monterey and requested a grant from Governor Juan Bautista Alvarado. Alvarado saw Sutter's plan of establishing a colony in the Central Valley as useful in "buttressing the frontier which he was trying to maintain against Indians, Russians, Americans and British."Dillion (1967), pp. 76–77. Sutter persuaded Governor Alvarado to grant him of land for the sake of curtailing American encroachment on the Mexican territory of California. Sutter was given the right to "represent in the Establishment of New Helvetia all the laws of the country, to function as political authority and dispenser of justice, in order to prevent the robberies committed by adventurers from the United States, to stop the invasion of savage Indians, and the hunting and trading by companies from the Columbia (river)." He named the settlement New Helvetia. In an 1841 inventory for John Sutter that described the settlement surrounding the fort: "twenty-four planked dwellings with glazed windows, a floor and a ceiling; each had a garden. There were eight sheds, eight bathhouses and ten kitchens."
