North America 1843: Oregon Dispute

Political map of North America & the Caribbean on 02 Oct 1843 (Manifest Destiny: Oregon Dispute), showing the following events: Jones’s War; Webster-Ashburton Treaty; Mier Expedition; Construction of Fort Victoria; Santo Tomás Colony; Naval Battle of Campeche; Creation of Provisional Government of Oregon; Great Migration of 1843.

By the early 1840s, American settlers, arriving overland in increasing numbers along what became known as the Oregon Trail, were beginning to challenge the dominance of Britain's Hudson's Bay Company in the jointly-occupied Oregon Country. In 1843, these settlers had enough influence to push through a pro-US provisional government, encouraging their supporters in the east to clamor for the US seizure of the entire region.
