Between the 1810s and 1850s, a sizable segment of the Klikatat Tribe of present-day south-central Washington occupied parts of the Willamette, Umpqua, and Rogue Valleys. Their expansion into Oregon Territory is a strong regional example of how, all along the western frontier, exposure to EuroAmericans changed the cultures and territories of Native people. Even though Klikatats were not native to Oregon, their influence was so strong during their brief presence there that their name became identified with the Territory. Their 1855 repatriation to Washington by Superintendent of Indian Affairs Joel Palmer is one of the first examples in Oregon of forced governmental removal of an entire ethnic group from lands they considered their homes.
