The Fort Walla Walla–Fort Colville Military Road was built in June 1859 to connect the Walla Walla area with its fairly easy access to the Columbia River to the mountainous area of the Huckleberry and Selkirk Mountains of current Northeast Washington and the Inland Northwest.
 Brigadier General William S. Harney, commander of the Department of Oregon, opened up the district north of the Snake River to settlers in 1858 and ordered Brevet Major Pinkney Lugenbeel, 9th Infantry Regiment (United States) to establish a U.S. Army post to restrain the Indians lately hostile to the U.S. Army's Northwest Division and to protect miners who flooded into the area after first reports of gold in the area appeared in Western Washington newspapers in July 1855.
 It was common practice to use existing Indian trails to develop military roads, and only make necessary improvements for the movement of artillery or supply trains.
 Brevet Major Lugenbeel followed the long established Indian trail, then Hudson Bay Company brigade trail from the U.S. Fort Walla Walla area to Hudson Bay Company Fort Colvile, but had to leave the trail at current Orin-Rice Road, two miles south of Colville, where the southernmost land claims of the Hudson Bay Company fort began.
 Washington Territorial Governor Isaac Stevens and the U.S. Army were ordered by the United States Department of State to honor land ownership claims by the Hudson Bay Company.
 Lugenbeel's command arrived from Fort Walla Walla on June 20, 1859; Pinkney Lugenbeel was later credited with improving and building up the Military Road.
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.
 Russians controlled most of the coast of what is now Alaska during the entire era.
 The coast south of Alaska endured fierce competition between, and among, British and American trading vessels.
 The British were the first to operate in the southern sector, but were unable to compete against the Americans, who dominated from the 1790s to the 1830s.
 The British Hudson's Bay Company entered the coast trade in the 1820s with the intention of driving the Americans away.
 This was accomplished by about 1840.
 In its late period, the maritime fur trade was largely conducted by the British Hudson's Bay Company and the Russian-American Company.
The Hudson's Bay Company (HBC; French: "Compagnie de la Baie d'Hudson" ), commonly referred to as The Bay (La Baie in French), is a Canadian retail business group.
 A fur trading business for much of its existence, Hudson's Bay Company owns and operates retail stores throughout Canada, Belgium, Germany, the Netherlands, and the United States with Galeria Kaufhof, Gilt, Hudson's Bay, Home Outfitters, Lord & Taylor, and Saks Fifth Avenue.
 HBC's head office is in the Simpson Tower in Toronto, Ontario.
 The company is listed on the Toronto Stock Exchange under the symbol "HBC".
Fort Nisqually was an important fur trading and farming post of the Hudson's Bay Company in the Puget Sound area, part of the Hudson's Bay Company's Columbia Department.
 It was located in what is now DuPont, Washington.
 Today it is a living history museum located in Tacoma, Washington, USA, within the boundaries of Point Defiance Park.
 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.
The Columbia District was a fur trading district in the Pacific Northwest region of British North America in the 19th century.
 Much of its territory overlapped with the disputed Oregon Country.
 It was explored by the North West Company between 1793 and 1811, and established as an operating fur district around 1810.
 The North West Company was absorbed into the Hudson's Bay Company in 1821, under which the Columbia District became known as the Columbia Department.
 The Oregon Treaty of 1846 marked the effective end of the Hudson's Bay Company's Columbia Department.
Fur brigades were convoys of canoes and boats used to transport supplies, trading goods and furs in the North American fur trade industry.
 Much of it consisted of native fur trappers and fur traders who travelled between their home trading posts and a larger Hudson's Bay Company or Northwest Company post in order to supply the inland post with goods and supply the coastal post with furs.
John Work (c. 1792 – 22 December 1861) was a chief factor of the Hudson's Bay Company and head of one of the original founding families in Victoria, British Columbia.
 Work joined the Hudson’s Bay Company in 1814 and served in many capacities until his death in 1861, ultimately becoming a member of the company’s Board of Management for its Western Department.
 He also served on Vancouver Island’s Legislative Council.
 At the time of his death, Work was the largest private land owner of Vancouver Island.
 Work left an important legacy in the form of sixteen journals which chronicle his trading expeditions from 1823 to 1851.
 His journals provide a detailed record of Pacific Northwest land features, native peoples, and the Hudson’s Bay Company’s fur trading business in the early 19th century.
The Romance of the Far Fur Country is a historical documentary film portraying Arctic fur trappers in 1919 to commemorate the 250th anniversary of the Hudson's Bay Company in 1920.
 It is one of the earliest documentaries depicting the lives of the Arctic fur trappers.
The Northern Traders Company was an enterprise engaged in the fur trading business in the Canadian North, with outposts in the Athabasca-Mackenzie River district in Alberta and the Northwest Territories during the early 20th century.
 They were in direct competition with the Hudson's Bay Company and controlled an estimated 8% of the fur trading market in the north by 1922.
 Its principal was Colonel J.K. "Peace River Jim" Cornwall who got a start in the Peace River and Lesser Slave Lake district in the early 1900s and expanded north after the 1911 takeover of Hislop & Nagle and their fur trading posts in the Northwest Territories.
 Northern Traders were engaged in river transportation, primarily to service its own fur trading posts, but they also provided commercial passenger and freight service on their steam-driven vessels.
 The company went into receivership in 1926 and struggled to remain in business for the next seven years while under the management of creditors.
 In 1931, the company was liquidated, with all stock being sold to the Hudson's Bay Company, and its transportation arm being sold and reorganized as Northern Waterways Limited.
Fort Garry, also known as Upper Fort Garry, was a Hudson's Bay Company trading post at the confluence of the Red and Assiniboine rivers in what is now downtown Winnipeg.
 It was established in 1822 on or near the site of the North West Company's Fort Gibraltar.
 Fort Garry was named after Nicholas Garry, deputy governor of the Hudson's Bay Company.
 It served as the centre of fur trade within the Red River Colony.
 In 1826, a severe flood destroyed the fort.
 It was rebuilt in 1835 by the HBC and named Upper Fort Garry to differentiate it from "the Lower Fort," or Lower Fort Garry, 32 km downriver, which was established in 1831.
 Throughout the mid-to-late 19th century, Upper Fort Garry played a minor role in the actual trading of furs, but was central to the administration of the HBC and the surrounding settlement.
 The Council of Assiniboia, the administrative and judicial body of the Red River Colony mainly run by Hudson's Bay Company officials, met at Upper Fort Garry.
