"Oregon Fever": Why Settlers Flocked to the Oregon Territory

Mid-19th century migrants were drawn by a potent mix of opportunity and ideology:

• Abundant Resources – Fertile Willamette Valley soil, vast timber, rich fisheries.
• Free Land – The Donation Land Claim Act (1850) granted 320–640 acres to settlers who cultivated it.
• Economic Prospects – Farming, logging, and the 1850s gold rush spurred boomtowns and commerce.
• Religious Freedom – Methodists, Presbyterians, and others sought autonomy to worship and build communities.
• Manifest Destiny – The belief that U.S. expansion to the Pacific was divinely ordained fueled national policy and personal ambition.

Together, these forces triggered one of America's largest voluntary overland migrations.
