The HBC founded Cumberland House (built by Samuel Hearne) as a major inland trading post, signaling a strategic shift from coastal Hudson Bay posts toward direct interior competition with Montreal-based traders linked to the NWC.
A Montreal-based coalition of independent fur traders organized what became the North West Company (NWC), creating a well-capitalized inland competitor to the Hudson’s Bay Company (HBC) and setting the stage for intensified rivalry across the northwest interior.
The NWC consolidated by merging with a rival firm (often described as Gregory, McLeod and Co.), strengthening its partner network and logistics—an organizational step that helped it challenge the HBC more effectively in the interior.
The XY Company (New North West Company) was created as a Montreal-based competitor, escalating competitive pressure in the fur country and contributing to instability and violence among trading post networks.
Facing border and customs complications after the U.S. Revolution, NWC partners ended their last Grand Portage rendezvous (1802) and moved operations to a new Lake Superior depot, a logistical change that reinforced NWC control of its inland supply chain.
By 1803 the NWC rendezvous had shifted to the Kaministiquia River area (later Fort William), becoming the key inland hub where furs and trade goods were exchanged between Montreal brigades and western posts.
After several years of costly rivalry, the XY Company was absorbed by the NWC, temporarily reducing competition within the Montreal trade while leaving the broader HBC–NWC struggle unresolved.
The NWC’s inland headquarters was renamed Fort William in honor of William McGillivray, reflecting the site’s central role in coordinating NWC operations and annual gatherings that underpinned its competitive reach.
The NWC established Fort Gibraltar at the confluence of the Red and Assiniboine rivers, positioning itself to control regional provisioning and trade routes—an action that sharpened conflict with the HBC-backed Selkirk Settlement.
The HBC issued a large land grant (often called the Selkirk Concession/Grant) to Thomas Douglas, 5th Earl of Selkirk, to establish an agricultural settlement at Red River—intended in part to supply provisions and strengthen HBC presence in the interior.
Governor Miles Macdonell issued the Pemmican Proclamation limiting pemmican exports from the Red River district, directly threatening NWC provisioning and helping trigger the wider escalation known as the Pemmican War.
At Seven Oaks near Red River, a Métis party associated with NWC provisioning confronted HBC/settlers; Governor Robert Semple and many of his men were killed. The clash became the best-known flashpoint of the Pemmican War and intensified calls to end the companies’ violence.
Lord Selkirk, traveling with disbanded soldiers (including men from the De Meuron regiment), seized the NWC headquarters at Fort William and detained several NWC leaders, escalating the legal and political struggle over responsibility for Red River violence.
British policy intervened to end the destabilizing conflict: an 1821 Act regulated the fur trade and jurisdiction in parts of British North America, and the companies were merged into a reconstituted Hudson’s Bay Company—formally closing the HBC–NWC rivalry as an independent contest.
