Klickitat people
In the early 1850s, the Klickitat Tribe raided present-day Jackson County, Oregon from the north and settled the area. Modoc, Shasta, Takelma, Latgawas, and Umpqua Indian tribes had already lived within the present boundaries of that county.
Indian Territory
The Wichita and Caddo both spoke Caddoan languages, as did the Kichai people, who were also indigenous to what is now Oklahoma and ultimately became part of the Wichita and Affiliated Tribes. The Wichita (and other tribes) signed a treaty of friendship with the US in 1835. The tribe's headquarters are in Anadarko, Oklahoma.
