In the nineteenth century, the Oregon Country was a disputed 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 maritime 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.

Adventure was built by the crew of Captain Robert Gray on his second voyage in the maritime fur trade to the Northwest Coast of North America. The 45-ton sloop was built to allow the trading venture to access smaller inlets the Columbia could not reach. At the end of his second voyage Gray sold the ship to the Spanish Navy. It was renamed Orcacitas and served the Naval Department of San Blas for some years.

Built at the entrance of the Columbia River in 1811, Fort Astoria was the first American-owned settlement on the Pacific coast of North America.

Fort Boise is either of two different locations in the western United States, both in southwestern Idaho. The first was a Hudson's Bay Company (HBC) trading post near the Snake River on what is now the Oregon border, dating from the era when Idaho was included in the British fur company's Columbia District. After several rebuilds, the fort was ultimately abandoned in 1854, after it had become part of United States territory following settlement in 1846 of the northern boundary dispute.

The trade center Fort Colvile was built by the Hudson's Bay Company (HBC) at Kettle Falls on the Columbia River in 1825 and operated in the Columbia fur district of the company. Named for Andrew Colvile, a London governor of the HBC, the fort was a few miles west of the present site of Colville, Washington. It was an important stop on the York Factory Express trade route to London via the Hudson Bay. The HBC for some time considered Fort Colvile second in importance only to Fort Vancouver, near the mouth of the Columbia, until the foundation of Fort Victoria.

Fort Hall was a fort that was built in 1834 as a fur trading post by Nathaniel Jarvis Wyeth.

The Fort Nisqually Granary, moved along with the Factor's House from the original site of the second fort to this park, is a U.S. National Historic Landmark. Built in 1843, the granary is the oldest building in Washington state and one of the only surviving examples of a Hudson's Bay Company "post on sill" structure. The Factor's House and the granary are the only surviving Hudson's Bay Company buildings in the United States.

Fort Vancouver was a 19th-century fur trading post that was the headquarters of the Hudson's Bay Company's Columbia Department, located in the Pacific Northwest. Named for Captain George Vancouver, the fort was located on the northern bank of the Columbia River in present-day Vancouver, Washington. The fort was a major center of the regional fur trading. Every year trade goods and supplies from London arrived either via ships sailing to the Pacific Ocean or overland from Hudson Bay via the York Factory Express. Supplies and trade goods were exchanged with a plethora of Indigenous cultures for fur pelts. Furs from Fort Vancouver were often shipped to the Chinese port of Guangzhou where they were traded for Chinese manufactured goods for sale in the United Kingdom. At its pinnacle, Fort Vancouver watched over 34 outposts, 24 ports, six ships, and 600 employees. Today, a full-scale replica of the fort, with internal buildings, has been constructed and is open to the public as Fort Vancouver National Historic Site.

He was noted for coming upon and naming the Columbia River in 1792, while on his second voyage.

Alexander Henry 'The Younger', was an early Canadian fur trader, explorer and diarist. From 1799 until his premature death in 1814 he kept an extensive diary which is the most complete record ever printed of the daily life of a fur trader in the north. His journals were an account of "personal doings", but cannot be considered a diary of inward thoughts. These journals cover everything that happened to him in a most matter-of-fact manner and have yielded much material for historians and other researchers of that time period in North American history. Henry married the daughter of Liard Ah-ne-him-ish Cottonwood Little Shell, the brother of the Great Pembina Chippewa Nation Grand Chief La Petite Coquille Little Shell I Corbeau and son of The Great Sioux Nation & The Great Pembina Chippewa Nation Wazhazha Mdewakanton Grand Chief Little Crow I Petit Corbeau Red Wing I.

The maritime fur trade was a ship-based fur trade system that focused on acquiring furs of sea otters and other animals from the indigenous peoples of the Pacific Northwest Coast and natives of Alaska. The furs were mostly sold in China in exchange for tea, silks, porcelain, and other Chinese goods, which were then sold in Europe and the United States. The maritime fur trade was pioneered by Russians, working east from Kamchatka along the Aleutian Islands to the southern coast of Alaska. British and Americans entered during the 1780s, focusing on what is now the coast of British Columbia. The trade boomed around the beginning of the 19th century. A long period of decline began in the 1810s. As the sea otter population was depleted, the maritime fur trade diversified and transformed, tapping new markets and commodities, while continuing to focus on the Northwest Coast and China. It lasted until the middle to late 19th century.

In May of that year, American merchant sea captain Robert Gray sailed into the Columbia River, becoming the first recorded European to navigate into it. The voyage, conducted on the privately owned Columbia Rediviva, was eventually used as a basis for the United States' claim on the Pacific Northwest, although its relevance to the claim was disputed by the British. As a result of the outcome the river was afterwards named after the ship. Gray spent nine days on the river trading fur pelts before sailing out of the river.

The Sager orphans were the children of Henry and Naomi Sager. In April 1844 the Sager family took part in the great westward migration and started their journey along the Oregon Trail. During it, both Henry and Naomi died and left their seven children orphaned. Later adopted by Marcus and Narcissa Whitman, missionaries in what is now Washington, they were orphaned a second time, when both their new parents, as well as brothers John and Francis Sager, were killed during the Whitman massacre in November 1847. About 1860 Catherine, the oldest daughter, wrote a first-hand account of their journey across the plains and their life with the Whitmans. Today it is regarded as one of the most authentic accounts of the American westward migration.

It took place in southeastern Washington state near the town of Walla Walla, Washington and was one of the most notorious episodes in the U.S. settlement of the Pacific Northwest. Whitman had helped lead the first wagon train to cross Oregon's Blue Mountains and reach the Columbia River via the Oregon Trail, and this incident was the climax of several years of complex interaction between him and the local Native Americans. The story of the massacre shocked the United States Congress into action concerning the future territorial status of the Oregon Country. The Oregon Territory was established on August 14, 1848.
