Map of Oregon Country
Oregon Country or
Oregon (to be distinguished from the
American State also called
Oregon)
was a predominantly
American term referring to a region of the
Pacific Northwest of
North America. The region was occupied by
British and
French Canadian fur traders from before 1810, and American settlers from the mid-1830s, with its coastal areas north from the Columbia River frequented by ships from all nations engaged in the fur trade, most of these from the 1790s through 1810s being Boston-based. The
Oregon Treaty of 1846 ended disputed joint occupancy pursuant to the
Treaty of 1818 and established the British-American boundary at the
49th parallel.
Oregon was a distinctly American term for the region. The British used the term
Columbia instead. The Oregon Country consisted of the land north of
42°N latitude, south of
54°40′N latitude, and west of the
Rocky Mountains to the
Pacific Ocean. The area now forms part of the present day
Canadian province of
British Columbia, all of the
US states of
Oregon,
Washington, and
Idaho, and parts of
Montana and
Wyoming. The British presence in the region was generally administered by the
Hudson's Bay Company, whose
Columbia Department comprised most of the Oregon Country and extended considerably north into
New Caledonia and beyond 54°40′N, with operations reaching to tributaries of the
Yukon River.
Early exploration
George Vancouver explored Puget Sound in 1792. Vancouver claimed it for
Great Britain on
4 June 1792, naming it for one of his officers,
Lieutenant Peter Puget.
Alexander Mackenzie was the first European to cross North America by land north of
Mexico since
Cabeza de Vaca of the
Narváez expedition., arriving at
Bella Coola on the what is now the
Central Coast of British Columbia in 1793. From 1804 to 1806
Meriwether Lewis and
William Clark scouted the territory for the United States on the
Lewis and Clark Expedition.
David Thompson, working for the
Montreal-based
North West Company, explored much of the region beginning in 1807, with his friend and colleague
Simon Fraser following the
Fraser River to its mouth in 1808, attempting to ascertain whether or not it was the Columbia, as had been theorized about it in its northern reaches through
New Caledonia, where it was known by its
Dakleh name as the "Tacoutche Tesse". Thompson was the first European to voyage down the entire length of
Columbia River. Along the way, his party camped at the junction with the
Snake River on July 9, 1811. He erected a pole and a notice claiming the country for Great Britain and stating the intention of the North West Company to build a trading post at the site. Later in 1811, on the same expedition, he finished his survey of the entire Columbia, arriving at a partially constructed
Fort Astoria just two months after the departure of
John Jacob Astor's ill-fated
Tonquin.
Name origin

The origin of the word
Oregon is not known for certain. One theory is that French Canadian fur company employees called the Columbia River "hurricane river"
le fleuve d'ouragan, because of the strong winds of the
Columbia Gorge.
George R. Stewart argued in a 1944 article in
American Speech that the name came from an engraver's error in a French map published in the early 1700s, on which the
Ouisiconsink (
Wisconsin River) was spelled "Ouaricon-sint", broken on two lines with the -sint below, so that there appeared to be a river flowing to the west named "Ouaricon". This theory was endorsed in
Oregon Geographic Names as "the most plausible explanation".
Territorial evolution
The Oregon Country was originally claimed by
Great Britain,
France,
Russia, and
Spain; the Spanish claim was later taken up by the
United States. The extent of the region being claimed was vague at first, evolving over decades into the specific borders specified in the US-British treaty of 1818. The U.S. based its claim in part on
Robert Gray's entry of the Columbia River in 1792 and the Lewis and Clark Expedition. Great Britain based its claim in part on British overland explorations of the Columbia River by
David Thompson and on prior discovery and exploration along the Coast. Spain's claim was based on the
Inter caetera and
Treaty of Tordesillas of 1493-94, as well as explorations the Pacific coast in the late 1700s. Russia based its claim off its explorations and trading activities in the region and asserted its ownership of the region by the
Ukase of 1821, which was quickly challenged by the other powers and withdrawn first to
51 degrees north, then to
54°40′N by separate treaties with the US and Britain in 1824 and 1825 respectively. Spain gave up its claims of exclusivity via the
Nootka Conventions of the 1790s. In the
Nootka Conventions , which followed the
Nootka Crisis Spain granted Britain rights to the Pacific Northwest, although it did not establish a northern boundary for Spanish California, nor did it extinguish Spanish rights to the Pacific Northwest. Spain later relinquished any remaining claims to territory north of the
42nd parallel to the United States as part of the
Adams-Onís Treaty of 1819. In the 1820s Russia gave up its claims south of 54°40′ and east of the
141st meridian in separate treaties with the United States and Britain.
Meanwhile, the United States and Britain negotiated the
Anglo-American Convention of 1818 that extended the boundary between their territories west along the
49th parallel to the Rocky Mountains. The two countries agreed to "joint occupancy" of the land west of the Rockies to the Pacific Ocean.
In 1821, as part of the forced merger between the
North West Company and the
Hudson's Bay Company the British Parliament imposed the laws of
Upper Canada on British subjects in
Rupert's Land and
Columbia District , and gave the authority to enforce those laws to the Hudson's Bay Company.
John McLoughlin, as chief factor of Fort Vancouver, applied the law to British subjects and sought to maintain law and order over American settlers as well.
In 1843 American settlers established their own government, called the
Provisional Government of Oregon. A legislative committee drafted a code of laws known as the
Organic Law. It included the creation of an executive committee of three, a judiciary, militia, land laws, and four counties. There was vagueness and confusion over the nature of the 1843 Organic Law, in particular whether it was a
constitutional or
statutory. In 1844 a new legislative committee decided to consider it statutory. The 1845 Organic Law made additional changes, including allowing the participation of British subjects in the government. Although the Oregon Treaty of 1846 settled the boundaries of US jurisdiction, the Provisional Government continued to function until 1849, when the first governor of Oregon Territory arrived.
A faction of Oregon politicians hoped to continue Oregon's political evolution into an independent nation, but pressure to join the
United States would prevail by 1848.

David Thompson of the British-owned
North West Company and later
Hudson's Bay Company penetrated the Oregon Country from the north, via
Athabasca Pass, arriving in 1807. In 1810,
John Jacob Astor founded the
Pacific Fur Company, which established a fur-trading post at
Astoria, Oregon in 1811. Thompson traveling down the
Columbia River reached the partially constructed Fort Astoria just two months after the departure of the ill-fated
Tonquin. Along the way he had camped and claimed the land at the future
Fort Nez Perces site at the confluence with the
Snake River. This initiated a very brief era of competition between American and British
fur traders. The Pacific Fur operation broke down during the
War of 1812 and was sold to the North West Company. Under British control, Astoria was renamed
Fort George.
In 1821 when the North West Company was merged with the Hudson's Bay Company, the British Parliament imposed the laws of
Upper Canada on British subjects in
Columbia District and
Rupert's Land, and gave the Hudson's Bay Company authority to enforce those laws.
John McLoughlin was appointed head or
Chief Factor of the Columbia Department in 1824. He moved its regional headquarters to
Fort Vancouver, which became the de facto political center of the Pacific Northwest. McLoughlin applied the laws to British subjects, kept peace with the natives and sought to maintain law and order over American settlers as well.
Astor continued to compete for Oregon Country furs through his
American Fur Company operations in the Rockies. In the 1820s, a few American explorers and traders visited this land beyond the
Rocky Mountains. Long after the
Lewis & Clark Expedition and also after the consolidation of the
fur trade in the region by the Canadian fur companies, American "
Mountain Men" such as
Jedediah Smith and
Jim Beckwourth came roaming into and across the Rocky Mountains, following Indian trails through the Rockies to California and Oregon. They were looking for
beaver pelts and other furs, which were had by
trapping but difficult to obtain in the Oregon Country due to the policy of the Hudson's Bay Company of creating a "fur desert", via deliberate over-hunting in order to make the country's frontiers with the US unprofitable for American ventures. The Mountain Men, like the
Metis employees of the Canadian fur companies, adopted
Indian ways and many of them married Indian women.
Reports of Oregon Country eventually circulated in the eastern United States. Some churches decided to send missionaries to convert the Indians.
Jason Lee, a
Methodist minister from
New York, was the first
Oregon missionary. He built a mission school for Indians in the
Willamette Valley in 1834. Others followed within a few years.
American settlers began to arrive from the east by the
Oregon Trail starting in the late 1830s, and came in increasing numbers each subsequent year. Increased tension led to the
Oregon boundary dispute. Both sides realized that settlers would ultimately decide who controlled the region. Belatedly, the Hudson's Bay Company, which had previously discouraged settlement as it conflicted with the lucrative fur trade, reversed their position. In 1841
James Sinclair guided more than 100 settlers from the
Red River Colony to settle on HBC farms near
Fort Vancouver, on orders from
Sir George Simpson. The Sinclair expedition crossed the Rockies into the
Columbia Valley, near present-day
Radium Hot Springs,
British Columbia, then traveled south-west down the
Kootenai River and Columbia River following the southern portion of the well established
York Factory Express trade route.

The Canadian effort proved to be too little, too late. For, in what was dubbed "
The Great Migration of 1843" or the "Wagon Train of 1843", an estimated 700 to 1000 emigrants left for Oregon. Britain ceded Columbia District south of the
49 parallel to the United States by the
Oregon Treaty in 1846.

The Oregon Treaty
In 1843, settlers in the
Willamette Valley established a provisional
government at
Champoeg, which was personally (but not officially) recognized by John McLoughlin of the Hudson's Bay Company in 1845.
Political pressure in the United States urged the occupation of all the Oregon Country. Expansionists in the American South wanted to annex Texas, while their counterparts in the Northeast wanted to annex the Oregon Country whole. It was seen as significant that the expansions be parallel, as the relative proximity to other states and territories made it appear likely that Texas would be pro-slavery and Oregon against slavery.

In the
1844 U.S. Presidential election, the Democrats called for expansion into both areas. After being elected, however, President
James K. Polk supported the
49th parallel as a northern limit for U.S. annexation in Oregon Country. It was Polk's uncompromising support for the expansion into Texas and relative silence on the
Oregon boundary dispute that led to the phrase "Fifty-Four Forty or Fight!", referring to the northern border of the region and often erroneously attributed to Polk's campaign. The goal of the slogan was to rally Southern expansionists (some of whom wanted to annex only Texas in an effort to tip the balance of slave/free states and territories in favor of slavery) to support the effort to annex Oregon Country, appealing to the popular belief in
Manifest Destiny. The British government, meanwhile, sought control of all territory north of the
Columbia River.
Despite the posturing, neither country really wanted to fight what would have been the third war in 70 years against the other. The two countries eventually came to a peaceful agreement in the 1846
Oregon Treaty that divided the territory west of the
Continental Divide along the
49th parallel to
Georgia Strait; with all of
Vancouver Island remaining under British control. This border still divides British Columbia from neighboring Washington, Idaho, and Montana.
During the 1840s the HBC shifted its
Columbia Department headquarters from
Fort Vancouver to
Fort Victoria on
Vancouver Island. The plan to move to a more northerly location dated back to the 1820s.
George Simpson was the main force behind the move north;
John McLoughlin became the main hindrance. McLoughlin had devoted his life's work to the Columbia business and his personal interests were increasingly linked to the growing settlements in the Willamette Valley. He fought Simpson's proposals to move north, but in vain. By the time Simpson made the final decision, in 1842, to move the headquarters to Vancouver Island, he had many reasons for doing so. There was a dramatic decline in the fur trade across North America. In contrast the HBC was seeing increasing profits with coastal exports of salmon and lumber to Pacific markets such as
Hawaii. Coal deposits on Vancouver Island had been discovered and steamships such as the
Beaver had shown the growing value of coal, economically and strategically. A general HBC shift toward Pacific shipping and away from the interior of the continent made
Victoria Harbour much more suitable than Fort Vancouver's location on the Columbia River. The
Columbia Bar at the river's mouth was dangerous and routinely meant weeks or months of waiting for ships to cross. The largest ships could not enter the river at all. Finally, the growing numbers of American settlers along the lower Columbia gave Simpson reason to question the long term security of Fort Vancouver. He worried, rightfully so, that the final border resolution would not follow the Columbia River. By 1842 he thought it more likely that the US would at least demand
Puget Sound, and the British government would accept a border as far north as the 49th parallel, excluding Vancouver Island. Despite McLoughlin's stalling, the HBC had begun the process of shifting away from Fort Vancouver and toward Vancouver Island and the northern coast in the 1830s. The increasing number of American settlers arriving in the Willamette Valley after 1840 served to make the need more pressing.
In 1848, the U.S. portion of the Oregon Country was formally organized as the
Oregon Territory. In 1849, Vancouver Island became a British
Crown colony, with the mainland being organized into the colony of British Columbia in 1858. Shortly after the establishment of Oregon Territory there was an effort to split off the region north of the Columbia River, which resulted in the creation of
Washington Territory in 1853.
Descriptions of the land
Alexander Ross, an early Scottish Canadian fur trader, describes the lower
Columbia River area of the Oregon Country (known to him as the
Columbia District):
"The banks of the river throughout are low and skirted in the distance by a chain of moderately high lands on each side, interspersed here and there with clumps of wide spreading oaks, groves of pine, and a variety of other kinds of woods. Between these high lands lie what is called the valley of the Wallamitte [sic], the frequented haunts of innumerable herds of elk and deer.... . In ascending the river the surrounding country is most delightful, and the first barrier to be meet with is about forty miles up from its mouth. Here the navigation is interrupted by a ledge of rocks, running across the river from side to side in the form of an irregular horseshoe, over which the whole body of water falls at one leap down a precipice of about forty feet, called
the Falls."
