Confederated Tribes of the Grand Ronde Community of Oregon

The Confederated Tribes of the Grand Ronde Community of Oregon (CTGR) is a federally recognized tribe of Indigenous peoples of the Northwest Plateau. They consist of at least 27 Native American tribes with long historical ties to present-day western Oregon between the western boundary of the Oregon Coast and the eastern boundary of the Cascade Range, and the northern boundary of southwestern Washington and the southern boundary of northern California.

The community has an Indian reservation, the Grand Ronde Indian Reservation. Established in 1856, the reservation occupies parts of Yamhill and Polk counties.

Because the tribes had lived near each other, and often spoke more than one language for use in trading, after they were grouped in the 19th century on the reservation, they refined a creole language that became known as Chinook Wawa. Although long forced to speak English, the people are working to conserve this Native language. They have taught Native speakers through immersion programs for young children. Provided by Wikipedia
