Why the U.S. Wanted Oregon Country (1840s)
The U.S. pursued Oregon Country (modern WA, OR, ID, MT, WY, BC) for seven strategic reasons:
- Pacific Ports: Access to Asia trade (Puget Sound, Columbia River).
- Manifest Destiny: Ideological drive for continental expansion.
- Boundary Dispute: Joint occupation with Britain (1818) was unstable; 49th parallel unresolved west of Rockies.
- Economic Resources: Timber, furs, fisheries, fertile Willamette Valley.
- Columbia River Control: Vital inland transport artery.
- Settler Pressure: Oregon Trail migrants demanded U.S. sovereignty.
- Geopolitics: Preempt Russian (Alaska) and British claims.
Resolved by 1846 Oregon Treaty (49th parallel to Strait of Juan de Fuca).
