Why did the Hudson’s Bay Company and North West Company merge in 1821?

The Hudson’s Bay Company and the North West Company merged in 1821 primarily to end nearly 40 years of bitter and often violent rivalry over the North American fur trade.12

This competition intensified significantly after 1811–12, when the Hudson’s Bay Company established the Red River Settlement in present-day Manitoba. The settlement was located across the North West Company’s primary supply and communication lines, leading to open conflict between the two organizations. Tensions culminated in the Seven Oaks Massacre in 1816, where a group of North West Company men—largely Métis—killed 20 members of a Hudson’s Bay Company-led group.3214

Following these armed clashes and ongoing legal disputes, the British government intervened and insisted that the two companies merge. The resulting union operated under the name and charter of the Hudson’s Bay Company, effectively ending the competition and terminating the long-standing canoe trade routes from Montreal to the west.1342
