How did settlers and government policies affect Northwest Coast Indian lands in Washington and Oregon?

Beginning in the 1840s, a massive influx of settlers encouraged by the U.S. government into present-day Washington and Oregon profoundly disrupted the lives of Northwest Coast Indians. This occupation was accompanied by the forced removal of tribes to small reservations under the terms of formal treaties.12

These government policies were part of a broader effort to assimilate indigenous peoples, which included the suppression of cultural practices and the imposition of agricultural lifestyles. In the late 19th century, the allotment process further reduced indigenous landholdings by replacing communal tribal titles with individual farm-sized plots, often leaving the remaining "surplus" land open to public sale and exploitation by speculators.345

Beyond land loss, the settlement movement and associated industrial activities—such as the commercial salmon cannery industry—severely damaged the natural resources upon which these tribes relied for subsistence. Despite these challenges, many tribes maintained economic independence through wage labor and later utilized legal strategies to assert their rights, most notably in the landmark United States v. Washington (1974) decision, which affirmed treaty-protected fishing rights.314
