Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians of Oregon

Lands ceded to the United States by treaty, law or executive order, 1854–1855, as Charles C. Royce recorded them in 1899 — 22,962 km² in 3 cessions across Oregon.

A cession records when the United States took title — not the full extent of a homeland, and much land was taken without any treaty. The link between each cession and present-day nations is the one the U.S. Forest Service and the National NAGPRA Program’s dataset records; the nation’s own account comes first.

Named in the treaties as: Calapooia · Umpqua · Coast tribes of Oregon · Indians on coast of Oregon
