Confederated Tribes of the Siletz Indians of Oregon — lands ceded, 1855–1857

Lands ceded to the United States by treaty, law or executive order, 1855–1857, as Charles C. Royce recorded them in 1899 — 48,358 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: Confederated Bands of Willamette valley · Calapooia · Coast tribes of Oregon
