Archeologists in the 1930s uncovered evidence that people have lived in what is now Oregon for over 9,000 years. The region has been continuously inhabited since then, supported by the bounty of a temperate climate and a varied ecosystem. While colonists from Europe were negotiating and warring their way into settlement along the East Coast, and Spain and Russia were planting flags and establishing missions on the upper and lower West Coast, Native peoples in the Pacific Northwest were building communities, developing trade networks, and forming political alliances. The region was bounded by mountain ranges and an unforgiving coastline, frequently obscured by fog. Native traders often left the Pacific Northwest to barter at foreign posts, but there is no evidence that foreigners penetrated the interior of the Oregon Country before 1792, when American Robert Gray sailed his ship, the Columbia Rediviva, over nautical terrors to enter a massive river he named Columbia.
It was as if a giant seal had been broken over the region. Among the many foreigners who traveled to the Columbia Basin in the early nineteenth century, the Americans and British were able to take the strongest foothold. Within a few years, the Americans had sent a military expedition to the region (Lewis and Clark in 1805–1806), closely followed by American and British fur traders. Missionaries, mountain men, settlers, and merchants came in the 1820s and 1830s.
The Oregon Trail became a highway for overland travel during the 1840s, bringing thousands to the Willamette Valley and securing American dominance in the region, a reality the United States reified through the Oregon Treaty with Great Britain in 1846. The trail was so heavily used that parts of it still scar the ground. In 1850, Congress passed the Oregon Donation Land Act, which gave free land to white men and women and sent negotiators to the Oregon Country to persuade Native tribes through treaties to cede their homelands to U.S. ownership. The treaty system was flawed for many reasons, not least among them because the process favored white settlers and forced Natives to negotiate under duress. The terms of the treaties led in part to a series of Indian wars that further devastated Native communities and solidified the white colonization of Oregon. The effort to remake Oregon into a white man’s region was explicitly outlined in the state constitution in 1857, which included restrictions on suffrage, land rights, and basic citizenship.
White Americans believed they had "discovered" and "civilized" the Oregon Country, but there is no corner of the land that had not been observed, lived on, named, or managed by Native people long before Gray navigated his ship to the interior. The landscape was an intimate part of Native economies, culture, and theology, and it remains so. The white settlement of Oregon imposed on that world view, but it did not diminish or destroy it.
