Klickitat people
The Klickitat (also spelled Klikitat) are a Native American tribe of the Pacific Northwest. Today most Klickitat are enrolled in the federally recognized Confederated Tribes and Bands of the Yakama Nation, some are also part of the Confederated Tribes of the Grand Ronde Community of Oregon.
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.
